stopping distance, and result in sudden
deflation (blowout) because they are more
likely to become punctured or damaged by
road debris, potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the
Tire and Loading Information placard on
the driver's door B‑pillar. Overloading the
tires can overheat them, possibly causing
a blowout. Overloading the tires can also
result in handling or steering problems, or
brake failure.
Check the tire inflation pressure at least
once a month.
Check and adjust the tire inflation
pressure when the tires are cold
Y
( page 127).
Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
X
Remove the cap from the valve on one tire.
X
Firmly press a tire gauge onto the valve.
X
Read the tire inflation pressure on tire
gauge and check against the
recommended tire inflation pressure on
the Tire and Loading Information
placard on the driver's door B‑pillar
Y
( page 132). If necessary, add air to
achieve the recommended tire inflation
pressure.
X
If you have overfilled the tire, release
tire inflation pressure by pushing the
metal stem of the valve with e.g. a tip of
a pen. Then recheck the tire inflation
pressure with the tire gauge.
X
Install the valve cap.
X
Repeat this procedure for each tire.

Tire Pressure Monitoring System (TPMS)*

Your vehicle may be equipped with a Tire
Pressure Monitoring System (TPMS).
* optional
Tires and wheels
It monitors the tire inflation pressure in
all four tires. A warning is issued to alert
you to a decrease in pressure in one or more
of the tires.
The Tire Pressure Monitoring System
(TPMS) is equipped with a combination low
tire pressure/TPMS malfunction telltale in
the instrument cluster. Depending on how
the telltale illuminates, it indicates a low
tire pressure condition or a malfunction in
the TPMS system itself:
If the telltale illuminates continuously,
R
one or more of your tires is significantly
underinflated. There is no malfunction
in the TPMS.
If the telltale flashes for 60 seconds and
R
then stays illuminated, the TPMS system
itself is not operating properly.
The TPMS only functions on wheels that are
equipped with the proper electronic
sensors.
G
Warning!
The TPMS does not indicate a warning for
wrongly selected inflation pressures.
Always adjust tire inflation pressure
according to the Tire and Loading
Information placard on the driver's door
B‑pillar.
The TPMS is not able to issue a warning due
to a sudden dramatic loss of pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by
carefully applying the brakes and avoiding
abrupt steering maneuvers.
G
Warning!
Each tire should be checked monthly when
cold and inflated to the inflation pressure
recommended by the vehicle manufacturer
on the Tire and Loading Information
placard. If your vehicle has tires of a
different size than the size indicated on
the Tire and Loading Information placard,
you should determine the proper tire
inflation pressure for those tires.
