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.

Install the valve cap.

Repeat this procedure for each tire.
Run Flat Indicator (Canada only)
While the vehicle is being driven, the Run Flat
Indicator monitors the set tire inflation pres-
sures by evaluating each wheel’s rotational
speed. This allows the system to detect a sig-
nificant loss of pressure in a tire. If a wheel’s
rotational speed changes due to falling tire
inflation pressure, you will see a correspond-
ing warning message in the multifunction dis-
play.
The Run Flat Indicator may function in a
restricted manner or with a delay

Warning!
When the multifunction display shows the
message Tire Pressure Check Tires,
one or more of your tires is significantly
underinflated. You should stop and check
your tires as soon as possible, and inflate
them to the proper tire inflation pressure as
indicated on the vehicle’s Tire and Loading
Information placard or, if available, on the
tire inflation pressure label.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Each tire, including the spare, should be
checked every other week when cold and
set to the recommended tire inflation pres-
sure as specified on the Tire and Loading
Information placard on the driver’s door
B-pillar or, if available, on the tire inflation
pressure label located on the inside of the
fuel filler flap.
i
The recommended tire inflation pressures
for your vehicle can be found on the Tire
and Loading Information placard located
on the driver’s door B-pillar (Y page 206)
or, if available, on the tire inflation pressure
label on the on the inside of the fuel filler
flap (Y page 197). The tire inflation pres-
sures are not listed in the Operator's Man-
ual.

Warning!
The Run Flat Indicator does not provide a
warning for wrongly selected tire inflation
pressures. Always adjust tire inflation pres-
sure according to the Tire and Loading
Information placard on the driver’s door
B-pillar or, if available, on the tire inflation
pressure label located on the inside of the
fuel filler flap.
The Run Flat Indicator does not replace reg-
ular checks of the tire inflation pressures
since a gradual pressure loss in more than
one tire cannot be detected by the Run Flat
Indicator.
The Run Flat Indicator is not able to issue a
warning due to a sudden dramatic loss of
tire inflation pressure (e.g. tire blowout
caused by a foreign object). In this case
bring the vehicle to a halt by carefully apply-
