Fig. 260 Tire pressure label
The correct tire pressure for tires
mounted at the factory and for
the spare tire* is indicated on a la-
bel. The label is located on the B-
pillar > fig. 259, > fig. 260. The
location may vary depending on
the model.
Use the tire pressure specified for
a normal vehicle load when the
vehicle is partially loaded > table
on page 331. If driving the vehi-
cle when fully loaded, you must
increase the tire pressure to the
maximum specified pressure > A.

Checking and correcting tire
pressure
>Check the tire pressure at least
once per month and also check it
before every long drive.
> Always check the tire pressure
when the tires are cold. Do not
reduce the pressure if it increas-
es when the tires are warm.
>Refer to the sticker > fig. 260
for the correct tire pressure.
>Correct the tire pressure if nec-
essary.
> Store the new tire pressure in
the Infotainment system
> page 338 or > page 341.
> Check the pressure in the emer-
gency tire*/spare tire*. Always
maintain the maximum temper-
ature that is specified for the
tire.
Z\ WARNING
Always adapt the tire pressure
to your driving style and the ve-
hicle load.
—Overloading can lead to loss of
vehicle control and increase
the risk of an accident. Read

ty precautions in > page 332,

tests, and does not include acceleration, cor-
nering, hydroplaning or peak traction charac-
teristics.
ZA WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
Z\ WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed.
Tire Pressure Monitoring
System indicator
(1) General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire
inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, 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 monitoring 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 tire 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 minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction 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.
If the Tire Pressure Monitoring System
indicator appears
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.
Using the ABS sensors, the tire pressure monitor-
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an @ indicator light 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 menu
display again each time the pressures change
(switching between partial and full load pres-
sure) or after changing or replacing a tire on your
vehicle > page 338. The tire pressure monitoring >

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 > A\.
> All passengers should leave the car and move

guardrail) > A\.

cle from rolling unintentionally > A\.

> If you are towing a trailer, unhitch the trailer
from your vehicle.
> Take the jack* > page 348 and the spare tire*

ZA\ 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.
—To help prevent the vehicle from moving
suddenly and possibly slipping off the jack*,
always fully set the parking brake and block
the front and back of the wheel diagonally
opposite the wheel being changed. When
one front wheel is lifted off the ground,
placing the Automatic Transmission in P
(Park) will not prevent the vehicle from mov-
ing.
— Before you change a wheel, be sure the
ground is level 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-
partment > page 60.
