WHAT TO DO IN AN EMERGENCY
!
TPMS (Tire pressure monitoring
system) malfunction indicator
The TPMS malfunction indicator comes
on and stays on when there is a problem
with the Tire Pressure Monitoring Sys-
tem. If Front Left sensor fails, the TPMS
malfunction indicator comes on, but if
Front Right, Rear Left, or Rear Right tire
is under-inflated, the low tire pressure
telltale may come on together with the
TPMS malfunction indicator.
Low tire pressure telltale
When the tire pressure monitoring sys-
tem warning telltale is illuminated, one
or more of your tires is significantly
under-inflated.
Immediately reduce your speed, avoid
hard cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pillar
outer panel. If you cannot reach a ser-
vice station or if the tire cannot hold the
newly added air, replace the low pres-
sure tire with the temporary spare tire.
Because the temporary spare tire is not
equipped with a tire pressure sensor,
the TPMS malfunction indicator will go
on and the Low Tire Pressure telltale
will go off after restarting and about 20
minutes of continuous driving before
you have the low-pressure tire repaired
and replaced on the vehicle.
WARNING:
Significantly low tire pressure makes
the vehicle unstable and can contrib-
ute to loss of vehicle control and
increased braking distances.
Continued driving on low pressure
tires will cause the tires to overheat
and fail.
CAUTION:
In winter or cold weather, the low tire
pressure telltale may be illuminated
if the tire pressure was adjusted to
the recommended tire inflation pres-
sure in warm weather. It does not
mean your TPMS is malfunctioning
because the decreased temperature
leads to a proportional lowering of
tire pressure.
When you drive your vehicle from a
warm area to a cold area or from a
cold area to a warm area, or the
outside temperature is greatly higher
or lower, you should check the tire
inflation pressure and adjust the tires
to the recommended tire inflation
pressure.
