Operation

Tires and wheels

With a spare wheel without wheel sensor

mounted, the system may still indicate the tire
inflation pressure of the removed wheel for some
minutes. If this happens, keep in mind that the
indicated value where the spare wheel is mount-
ed does not reflect the actual spare tire inflation
pressure.

Warning!

The TPMS does not indicate a warning for

wrongly selected inflation pressures. Always

adjust tire inflation pressure according to

the placard on the driver’s door B-pillar or, if

available, the supplemental tire pressure in-

formation on the inside of the fuel filler flap.

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 care-

fully applying the brakes and avoiding

abrupt steering maneuvers.

Warning!

Each tire, including the spare (if provided),

should be checked monthly when cold and

inflated to the inflation pressure recom-

mended by the vehicle manufacturer on the

vehicle placard or the tire inflation pressure

label. (If your vehicle has tires of a different

size than the size indicated on the vehicle

placard or the tire inflation pressure label,

you should determine the proper tire infla-

tion pressure for those tires).

As an added safety feature, your vehicle has

been equipped with a tire pressure monitor-

ing system (TPMS) that illuminates a low tire

pressure telltale when one or more of your

tires is significantly under-inflated. Accord-

ingly, when the low tire pressure telltale illu-

minates, you should stop and check your

tires as soon as possible, and inflate them to

the proper pressure. Driving on a significant-

ly under-inflated tire causes the tire to over-

heat and can lead to tire failure.

Under-inflation also reduces fuel efficiency

and tire tread life, and may affect the vehi-

cle’s handling and stopping ability. Please

note that the TPMS is not a substitute for

proper tire maintenance, and it is the driv-

er’s responsibility to maintain correct tire

pressure, even if under-inflation has not

reached the level to trigger illumination of

the TPMS low tire pressure telltale.
