Checking the tire pressures

Important safety notes

Observe the notes on tire pressure

(

Y

page 572).

Information on air pressure for the tires on

your vehicle can be found:

R

on the vehicle's Tire and Loading Informa-

tion placard on the B-pillar

R

on the tire pressure label on the fuel filler

flap

R

in the "Tire pressure" section

Checking tire pressures manually

To determine and set the correct tire pres-

sure, proceed as follows:

X

Remove the valve cap of the tire that is to

be checked.

X

Press the tire pressure gauge securely onto

the valve.

X

Read the tire pressure and compare it with

the recommended value on the Tire and

Loading Information placard (

Y

page 572).

X

If the tire pressure is too low, increase it to

the recommended value.

X

If the tire pressure is too high, release air by

pressing down the metal pin in the valve.

Use the tip of a pen, for example. Then,

check the tire pressure again using the tire

pressure gauge.

X

Screw the valve cap onto the valve.

X

Repeat these steps for the other tires.

Tire pressure monitor

General notes

If a tire pressure monitor is installed, the vehi-

cle's wheels have sensors that monitor the

tire pressures in all four tires. The tire pres-

sure monitor warns you if the pressure drops

in one or more of the tires. The tire pressure

monitor only functions if the correct sensors

are installed on all wheels.
Information on tire pressures is displayed in

the multifunction display. After a few minutes

of driving, the current tire pressure of each

tire is shown in the

Service

Service

menu of the mul-

tifunction display.

Example: current tire pressure display

For information on the message display, refer

to the "Checking the tire pressure electroni-

cally" section (

Y

page 577).

WARNING

Each tire, including the spare (if provided),

should be checked at least once a month

when cold and inflated to the pressure rec-

ommended by the vehicle manufacturer on

the Tire and Loading Information placard on

the driver's door B-pillar or the tire pressure

label on the inside of the fuel filler flap. If your

vehicle has tires of a different size than the

size indicated on the Tire and Loading Infor-

mation placard or the tire pressure label, you

should determine the proper tire 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 pres-

sure telltale when one or more of your tires

are significantly underinflated. 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 significantly underin-

flated tire causes the tire to overheat and can
