Using the Tire and Loading Information
placard on the driver’s door B-pillar
(Y page 206) or, if available, the supple-

Restart the TPMS after adjusting the tire
inflation pressure to the inflation pressure
recommended for the vehicle operating
condition. Tire pressure should only be
adjusted on cold tires. Observe the recom-
mended tire inflation pressure on the Tire
and Loading Information placard on the
driver’s door B-pillar. Some vehicles may
have supplemental tire pressure informa-
tion for driving at high speeds or for vehicle
loads less than the maximum loaded vehi-
cle condition. If such information is pro-
vided, it can be found on the inside of the
fuel filler flap.
