Wheels
As an added safety feature, your vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illuminates a low tire pressure tell
tale when one or more of your tires is significant
ly under-inflated . Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi
cantly under-inflated tire causes the tire to over
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and ti re tread life,
and may affect the vehicle's handling and stop
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re
sponsibility to maintain correct tire pressure,
even if under- inflation has not reached the level
to trigger illumination of the TPMS low tire pres
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys
tem is not operating properly. The TPMS mal
function indicator is combined with the low tire
pressure telltale . When the system detects a
malfunction, the telltale will flash for approxi
mately one m inute and then remain cont inuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal
function exists .
When the malfunct ion indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

Tire pressure monitoring system
Applies to: vehicles with Tire Pressure Monitoring System in
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 194 Instrumen t cl uster : indicator l ig ht with me ssage
Using the ABS sensors, the tire pressure monitor
ing system compares the tire tread circumfer
ence and vibration characteristics of the individu
al tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
Rt] and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
¢ page 231. The tire pressure mon i
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢page 221, fig. 193.
Tire tread circumference and vibrat ion character
istics can change and cause a tire pressure warn
ing if :
- the tire pressure in one or more tires is too low.
- the tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored¢

Replacing wheels
Before changing a wheel
Observe the following precautions for your own
and your passenger's safety when changing a
wheel.
.. After you experience a tire failure, pull the car
well away from moving traffic and try to reach
level ground before you stop c::> &.,.
.. All passengers should leave the car and move
to a safe location (for instance, beh ind the
guardrai l) ¢ ,&. .
.. Engage the
parking brake to prevent your vehi
cle from rolling unintentionally ¢,&. .
.. Move
selector lever to position P ¢ ,&. .
.. If you are towing a trailer, unhitch the trailer
from your vehicle .
.. Take the
jack and the spare tire* out of the lug
gage compartment ¢
page 240.
.8, WARNING
You or your passengers could be injured while
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the
emergency flashers on and use other warn
ing devices to alert other motorists.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
Emergency assistance
- To help prevent the vehicle from moving
suddenly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be
ing changed . When one front wheel is lifted
off the ground, placing the Automatic
Transmission in P (Park) wi ll
not prevent the
veh icle from moving.
- Before you change a wheel, be sure the
ground is leve l and firm. If necessary, use a
sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com
pa rtment

(D Tips
Before changing the wheel, you must activate
the jacking mode, so that the automatic con
trols for the Adaptive Air Suspension* do not
make it more difficult to lift the vehicle with
the jack ¢
