Checking tire inflation pressure
manually
Follow the steps below to achieve correct
tire inflation pressure:
̈ Remove the cap from the valve on one
tire.
̈ Firmly press a tire gauge onto the
valve.
̈ Read tire inflation pressure on tire
gauge and check against the recom-
mended tire inflation pressure on the
Tire and Loading Information placard
on the driver’s door B-pillar
(
page 269). If necessary, add air to
achieve the recommended tire inflation
pressure.
̈ Install the valve cap.
̈ Repeat this procedure for each tire.
Checking tire inflation pressure
electronically with the Advanced Tire
Pressure Monitoring System
(Advanced TPMS)
i
If you have overfilled the tire, release tire in-
flation pressure by pushing the metal stem of the
valve with e.g. a tip of a pen. Then recheck the
tire inflation pressure with the tire gauge.
i
USA only:
The T
ire Pressure Monitoring System (TPMS) is
equipped with a combination low tire pres-
sure/TPMS malfunction telltale in the instru-
ment cluster (
page 29). Depending on how the
telltale illuminates, it indicates a low tire pres-
sure condition or a malfunction in the TPMS sys-
tem itself:
ț If the telltale illuminates continuously,
one or more of your tires is significantly
under-inflated. There is no malfunction in
the TPMS.
ț If the telltale flashes for 60 seconds and
then stays illuminated, the TPMS system
itself is not operating properly.
