Installing a wheel
It is important to install wheels properly.
1. Clean the contact surfaces on the wheel and
hub.
2. Lift the wheel and place it on the hub.
3. Install the wheel bolts and tighten hand-tight.
Using the lug wrench, tighten crosswise until
all bolts are snug.
4. Lower the vehicle to the ground and alter-
nately tighten the bolts crosswise to
103 ft. lbs. (140 Nm).
5. Press the plastic covers onto the wheel bolts.
CAUTION
•
After inflating the tires, always reinstall
the valve cap to help avoid damage to the
valve from dirt, gravel, etc.
•
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.

Tire Pressure Monitoring System
(TPMS)
TPMS provides a warning if inflation pressure in
one or more tires is too low. It also uses a sym-
bol (called a telltale) that will flash for
60 seconds and then glow steadily if there is a
system malfunction.
TPMS uses the rotational speed of the tires in
combination with signal analysis of the ABS sen-
sor signals to determine if they are properly infla-
ted. When a tire is under-inflated, its diameter
(and consequently also its rotational speed)
changes. By comparing the individual tires with
each other it is possible to determine if one or
more tires are under inflated. If inflation pressure
is too low, an indicator symbol will illuminate in
the instrument panel and a text message will be
displayed.
Symbol Explanation
The symbol illuminates to indicate
low tire inflation pressure.
If a malfunction occurs in the sys-
tem, the tire pressure warning sym-
bol will flash for approximately
1 minute and then remain illumi-
nated.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to
