I have searched through the threads on TPMS and the like and am more confused than ever. I got my GX4H in July 14 and wasn't aware of any TPMS until a day ago when I got a bong and a warning symbol on the main dash at start up. I can found no reference to the system in the handbook. No tyre looked particularly flat so I drove to a service station and the warning disappeared. I checked but found all tyres were not far off the 35psi I usually have them at. It did lead me to check wear though and the outer edges of the fronts look worn so I'll be off to a tyre dealer to get them checked and rotated. I'm puzzled and a little paranoid now as to what caused the warning. If my car has a TPMS, I assumed it was the ABS type and I thought that would only operate when in motion? Could anyone tell me what system I've got and what may have caused it to briefly indicate please?

Why didn't you check the pressures with the supplied pump before driving off? We've had some quite cold nights recently, so by the time you drove to the service station the heat in the tyres could have brought the pressure back up over the trigger limit which seems to be about 30psi. BTW - a July'14 car probably has non-ABS TPMS.
 
Thanks for responses. 7.72 in my manual - OGGE14E3- is about towing. I suppose I could have got a car with a form of TPMS fitted but an old manual...I honestly didn't think of using the supplied pump but there is a garage less than a mile from home and I doubt that I warmed the tyres enough in that distance to make much difference. Having never had the warning before in 20 months I am inclined to think it was spurious but it looks like rotating the wheels is necessary anyway and I'll pay for a complete inspection and tracking if needs be, for peace of mind. The absence of a spare and the need to make an urgent journey concentrated my mind.
 
Here's a cut and paste from the manual I have in PDF form. May be of some use although the separate notes etc have not carried over in their numerous boxes.

Tyre pressure monitoring
system (TPMS)

The tyre pressure monitoring system (TPMS)
uses tyre inflation pressure sensors (A) on the
wheels to monitor the tyre inflation pressures.
The system only indicates when a tyre is significantly
under-inflated.
The base tyre pressure can be set at desired
value by the driver with the reset function execution.
(The low pressure warning threshold
is set based on the reset.)
The tyre inflation pressure sensor IDs for two
sets of tyres can be registered by a
MITSUBISHI MOTORS Authorized Service
Point, and the valid ID set can be switched by
the multi-information display switch. (It’s
beneficial in case of seasonal tyre change between
summer tyre and winter tyre.)

NOTE
The tyre pressure monitoring system
(TPMS) is not a substitute for regularly
checking tyre inflation pressures.
Be sure to check the tyre inflation pressures
as described in “Tyres” on page 11-10.
The tyre inflation pressure sensor (B) is installed
in the illustrated location.
Replace grommet and washer (C) with a
new one when the tyre is replaced.
For details, please contact your
MITSUBISHI MOTORS Authorized Service
Point.

When the operation mode is put in ON, the
tyre pressure monitoring system warning
lamp normally illuminates and goes off a few
seconds later.
If one or more of the vehicle tyres is significantly
under-inflated, the warning lamp will
remain illuminated while the operation mode
is in ON.
Refer to “If the warning lamp/display illuminates
while driving” on page 7-74 and take
the necessary measures.

NOTE
In addition, the warning display will be displayed
on the information screen in the multi-
information display.

CAUTION
If the warning lamp does not illuminate
when the operation mode is put in ON, it
means that the tyre pressure monitoring system
(TPMS) is not working properly. Have
the system inspected by a MITSUBISHI
MOTORS Authorized Service Point.
In such situations, a malfunctioning of the
system may be preventing the monitoring of
the tyre pressure. Avoid sudden braking,
sharp turning and high-speed driving.

If a malfunction is detected in the tyre pressure
monitoring system (TPMS), the warning
lamp will blink for approximately 1 minute
and then remain continuously illuminated.
The warning lamp will issue further
warnings each time the Plug-in Hybrid EV
System is restarted as long as the malfunction
exists.
Check to see whether the warning lamp goes
off after few minutes driving.
If it then goes off during driving, there is no
problem.
However, if the warning lamp does not go
off, or if it blinks again when the Plug-in
Hybrid EV System is restarted, have the vehicle
inspected by a MITSUBISHI
MOTORS Authorized Service Point.
In such situations, a malfunctioning of the
system may be preventing the monitoring of
the tyre pressure. For safety reasons, when
the warning lamp appears while driving,
avoid sudden braking, sharp turning and
high-speed driving.

NOTE
In addition, the warning display will be displayed
on the information screen in the multi-
information display.

Each tyre, including the spare (if so equipped),
should be checked monthly when cold
and inflated to the inflation pressure recommended
by the vehicle manufacturer on the
tyre inflation pressure label. (If your vehicle
has tyres of a different size than the size indicated
on the tyre inflation pressure label, you
should determine the proper tyre inflation
pressure for those tyres.)
As an added safety feature, your vehicle has
been equipped with the tyre pressure monitoring
system (TPMS) that illuminates a low
tyre pressure telltale when one or more of
your tyres is significantly under-inflated.
Accordingly, when the low tyre pressure telltale
illuminates, you should stop and check
your tyres as soon as possible, and inflate
them to the proper pressure. Driving on a significantly
under-inflated tyre causes the tyre
to overheat and can lead to tyre failure.

Under-inflation also reduces fuel efficiency
and tyre tread life, and may affect the vehicle’s
handling and stopping ability.
Please note that the tyre pressure monitoring
system (TPMS) is not a substitute for proper
tyre maintenance, and it is the driver’s responsibility
to maintain correct tyre pressure,
even if under-inflation has not reached the
level to trigger illumination of the tyre pressure
monitoring system (TPMS) low tyre
pressure telltale.
Your vehicle has also been equipped with a
warning lamp to indicate when the system is
not operating properly.
The warning lamp is combined with the low
tyre pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one minute
and then remain continuously illuminated.
This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the warning lamp is illuminated, the
system may not be able to detect or signal
low tyre pressure as intended.
The tyre pressure monitoring system (TPMS)
malfunctions may occur for a variety of reasons,
including the installation of replacement
or alternate tyres or wheels on the vehicle
that prevent the tyre pressure monitoring
system (TPMS) from functioning properly.
Always check the tyre pressure monitoring
system (TPMS) malfunction telltale after replacing
one or more tyres or wheels on your
vehicle to ensure that the replacement or alternate
tyres and wheels allow the tyre pressure
monitoring system (TPMS) to continue
to function properly.

If the warning lamp/display illuminates
while driving

If the warning lamp illuminates, avoid
hard braking, sharp steering manoeuvres
and high speeds. You should stop and
adjust the tyres to the proper inflation
pressure as soon as possible. Adjust the
spare tyre at the same time. Refer to
“Tyres” on page 11-10.

NOTE
In addition, the warning display will be displayed
on the information screen in the multi-
information display.
When inspecting or adjusting the tyre pressure,
do not apply excessive force to the
valve stem to avoid breakage.

NOTE
After inspecting or adjusting the tyre pressure,
always reinstall the valve cap on the
valve stem.
Without the valve cap, dirt or moisture could
get into the valve, resulting in damage to the
tyre inflation pressure sensor.
Do not use metal valve caps, which may
cause a metal reaction, resulting in corrosion
and damage of the tyre inflation pressure
sensors.
1. Once adjustments have been made, the
warning lamp will go off after a few minutes
of driving.
2. If the warning lamp remains illuminated
after you have been driving for about 10
minutes after you adjust the tyre inflation
pressure, one or more of the tyres
may have a puncture. Inspect the tyre
and if it has a puncture, have it repaired
by a MITSUBISHI MOTORS Authorized
Service Point as soon as possible.

WARNING
If the warning lamp/display illuminates
while you are driving, avoid hard braking,
sharp steering manoeuvres and high
speeds.
Driving with an under-inflated tyre adversely
affects vehicle performance and
can result in an accident.

CAUTION
The warning lamp/display may not illuminate
immediately in the event of a tyre blowout
or rapid leak.

NOTE
To avoid the risk of damage to the tyre inflation
pressure sensors, have any punctured
tyre repaired by a MITSUBISHI MOTORS
Authorized Service Point. If the tyre repair is
not done by a MITSUBISHI MOTORS Authorized
Service Point, damage to the tyre
inflation pressure sensor is not covered by
your warranty.
Do not use an aerosol puncture-repair spray
on any tyre.
Such a spray could damage the tyre inflation
pressure sensors.
Have any puncture repaired by a
MITSUBISHI MOTORS Authorized Service
Point.
Using the tyre repair kit may damage the
tyre inflation pressure sensor. The vehicle
must promptly be inspected and repaired by
a MITSUBISHI MOTORS Authorized Service
Point after using the tyre repair kit.

The tyre pressure monitoring system (TPMS)
may not work normally in the following circumstances:
A wireless facility or device using the
same frequency is near the vehicle.
Snow or ice is stuck inside the fenders
and/or on the wheels.
The tyre inflation pressure sensor’s battery
is dead.
Wheels other than MITSUBISHI
MOTORS GENUINE wheels are being
used.
Wheels that are not fitted with tyre inflation
pressure sensors are being used.
Wheels whose ID codes are not memorized
by the vehicle are used.
A window tint that affects the radio
wave signals is installed.

NOTE
Tyre inflation pressures vary with the ambient
temperature. If the vehicle is subjected to
large variations in ambient temperature, the
tyre inflation pressures may be underinflated
(causing the warning lamp/display come on)
when the ambient temperature is relatively
low. If the warning lamp/display comes on,
adjust the tyre inflation pressure.
Whenever the tyres and wheels
are replaced with new ones

If new wheels with new tyre inflation pressure
sensors are installed, their ID codes must
be programmed into the tyre pressure monitoring
system. Have tyre and wheel replacement
performed by a MITSUBISHI
MOTORS Authorized Service Point to avoid
the risk of damaging the tyre inflation pressure
sensors. If the wheel replacement is not
done by a MITSUBISHI MOTORS Authorized
Service Point, it is not covered by your
warranty.

CAUTION
The use of non-genuine wheels will prevent
the proper fit of the tyre inflation pressure
sensors, resulting air leakage or damage of
the sensors.

Reset of low tyre pressure
warning threshold

The threshold is set based on the tyre pressure
which the reset function is executed by
following procedure.
1. Operate the multi-information display
switch to switch the information screen
to the menu screen.
Refer to “Multi information display
switch” on page 6-05.
Refer to “Changing the function settings”
on page 6-16.
2. Lightly press the multi-information display
switch to select “ ” (reset
of low tyre pressure warning threshold).
3. Hold down the multi-information display
switch for about 3 seconds or more,
the buzzer sounds.
4. The warning lamp start flashing slowly.
5. Drive for a while. The reset is completed
if the warning lamp goes out.

NOTE
The reset function should be executed every
time when the tyre pressure or tyre rotation
is adjusted.
The reset function should be executed when
the tyre is cold. If it is executed when the
tyre is warm (e.g. after driving), there may
be a low tyre pressure warning earlier than
usual.

Tyre ID set change

In case that 2 sets of tyre inflation pressure
sensor ID are registered in the receiver, the
valid tyre ID set can be changed by following
procedure.
1. Operate the multi-information display
switch to switch the information screen
to the menu screen.
Refer to “Multi information display
switch” on page 6-05.
Refer to “Changing the function settings”
on page 6-16.
2. Lightly press the multi-information display
switch to select “ ” (tyre
ID set change).
3. Hold down the multi-information display
switch for about 3 seconds or more.
The setting changes the selected tyre ID
set.
4. The valid tyre ID set is changed, and the
number of the tyre pressure monitoring
system (TPMS) SET indicator is
changed.

NOTE
Each time this procedure is done, the tyre ID
set is changed. (1 - 2 - 1 - 2 …)
The tyre ID set is NOT changed, in case that
only 1 set of ID is registered.

When changing the tyre ID set, the reset
function of low tyre pressure warning
threshold is automatically started. (The
warning lamp start flashing slowly.) If the
tyre is warm at this time. the reset function
should be executed again when the tyre is
cold.

Here we go again - Low Tire (don't you just hate the American spelling in a car not sold there yet :twisted: !) Pressure Warning message this morning - and, yes, when I checked all the tyres ( :ugeek: ) they were down to 2.1 except for one at 2.0, which presumably triggered the alarm due to it being the 1st September :D

I assume this means summer is now officially over and I'm going to start wishing I didn't have only a Gx3h :lol:
 
Just a word of warning....

The air pressure machines in the majority of garages are installed, and then never calibrated again. They sit there in all weathers, and it's possible that when you use them it isn't air they are pumping in, but water vapour, and maybe even water. So

This from a friend of mine who works for the service department of a large prestige vehicle dealership where they have theirs calibrated annually.

I've found the supplied cigar light pump works a treat - so never need the garages ones :D
 
Thank you Claymore for your April 2016 posting regarding the TPMS. We get the TPMS messages mainly during the winter until the tyres warm up. I couldn't locate the info anywhere so thank you for posting it.
