Reactivating the TPMS
The TPMS must be reactivated when you
have adjusted the tire inflation pressure to
a new level (e.g. because of different load
or driving conditions). The TPMS is then
recalibrated to the current tire inflation
pressures.
̈ Using the Tire and Loading Information
placard on the driver’s door B-pillar
(
୴ page 389) or, if available, the
supplemental tire inflation pressure
information on the inside of the fuel
filler flap (
୴ page 375), make sure the
tire inflation pressure of all four tires is
correct.
̈ Press button è or ÿ on the mul-
tifunction steering wheel repeatedly
until the standard display menu ap-
pears in the multifunction display
(
୴ page 157).
̈ Press the j or k button repeat-
edly until you see the following
message:
Tire pressure monitor

Menu: R-Button
TPMS malfunctions may occur for a variety
of reasons, including the installation of in-
compatible 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.
i
If a condition causing the TPMS to malfunc-
tion develops, it may take up to 10 minutes for
the system to signal a malfunction using the
TPMS telltale flashing and illumination se-
quence.
The telltale extinguishes after a few minutes driv-
ing if the malfunction has been corrected.
i
Operating radio transmission equipment
(e.g. wireless headsets, two-way radios) in or
near the vehicle could cause the TPMS to mal-
function.
Warning! G
It is the driver’s responsibility to calibrate
the TPMS on the recommended cold infla-
tion pressure. Underinflated tires affect the
ability to steer or brake the vehicle. You
might lose control over the vehicle.
i
Reactivate the TPMS after adjusting the tire
inflation pressure to the inflation pressure rec-
ommended for the vehicle operating condition.
Tire pressure should only be adjusted on cold
tires. Observe the recommended tire inflation
pressure on the Tire and Loading Information
placard on the driver’s door B-pillar
(
୴ page 389). Some vehicles may have supple-
mental tire inflation pressure information for
driving at high speeds (
୴ page 395) or for vehi-
cle loads less than the maximum loaded vehicle
condition (
୴ page 395). If such information is
provided, it can be found on the inside of the fuel
filler flap.
