Recommended tire pressure
The tire pressure placard on the driver's side B
pillar (between the front and the rear door) indi-
cates tire pressure for different loads and speed
conditions.
The decal specifies the designation for the fac-
tory-mounted tires on the vehicle, as well as load
limits and inflation pressures.

Tire pressure monitoring system*
The tire pressure monitoring system
6
provides a
warning symbol in the instrument panel if pres-
sure is too low in one or more tires.
Symbol Explanation
This symbol illuminates to indicate
low inflation pressure.
If there is a system malfunction, the
inflation pressure warning symbol
will flash for approximately one
minute and then glow steadily.
System description
The tire pressure monitoring system measures
differences in rotational speed between the
wheels through the ABS system to determine if
the tires are properly inflated. If inflation pressure
in a tire is too low, its diameter (and consequently
its rotational speed) changes. By comparing the
tires with each other, the system can determine if
the pressure in one or more tires is too low.
General information about the tire pressure
monitoring system
In the following description, the tire monitoring
system is generally referred to as TPMS.
Each tire, including the spare (if provided)
7
should be checked monthly when cold and infla-
ted to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
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 is
significantly under-inflated. 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 under-inflated tire cau-
ses the tire to overheat and can lead to tire fail-
ure. Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire main-
tenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-infla-
tion has not reached the level to trigger illumina-
tion of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
