Press the çbutton.Checking tire pressure electronically
with the Advanced Tire Pressure Moni-
toring System (Advanced TPMS)*,
(Canada only)
The TPMS only functions on wheels that
are equipped with the proper electronic
sensors. It monitors the tire inflation pres-
sure, as selected by the driver, in all four
tires. A warning is issued to alert you to a
decrease in pressure in one or more of the
tires.
Tire pressure inquiries are made using the
multifunction display. The present inflation
pressures are displayed only after a few
minutes’ travel time.
i
Reactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire pressure should only be adjusted on cold
tires. Observe the recommended tire inflation
pressure on the placard on the driver’s door
B-pillar (
page 369). Some vehicles may have
supplemental tire pressure information for driv-
ing at high speeds (
page 375) or for vehicle
loads less than the maximum loaded vehicle con-
dition (
page 375). If such information is pro-
vided, it can be found on the inside of the fuel
filler flap.
i
Possible differences between the readings
of a tire pressure gauge of an air hose, e.g. gas
station equipment, and the vehicle’s control
system can occur. Usually the readings issued by
the control system are more precise.

underinflated and overinflated tires
Underinflated tires
Underinflated tires can:
cause excessive and uneven tire wear
adversely affect fuel economy
lead to tire failure from being
overheated
adversely affect handling
characteristicsOverinflated tires
Overinflated tires can:
adversely affect handling
characteristics
cause uneven tire wear
be more prone to damage from road
hazards
adversely affect ride comfort
increase stopping distance
Warning!
G
Follow recommended tire inflation
pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly,
adversely affect handling and fuel economy,
and are more likely to fail from being
overheated.
Warning!
G
Follow recommended tire inflation
pressures.
Do not overinflate tires. Overinflated tires
can adversely affect handling and ride
comfort, wear unevenly, increase stopping
distance, and result in sudden deflation
(blowout) because they are more likely to
become punctured or damaged by road
debris, potholes etc.
402 OperationMaintenanceClearing the maintenance service
indicator message
The maintenance service indicator mes-
sage is automatically cleared

Vehicles equipped with FSS PLUS (
Flexible
Service
System PLUS) only (Canada vehicles):
FSS PLUS evaluates engine temperature, oil
level, vehicle speed, engine speed, distance
driven and the time elapsed since your last
service and calculates other maintenance
service work required.
The interval between maintenance services
depends on your driving habits. A gentle driv-
ing style, moderate engine speeds and the
avoidance of short-distance trips will length-
en the interval between services.
