vehicle control, vehicle rollover, personal
injury and death. Additionally, the use of
non-recommended tires and wheels
could cause steering, suspension, axle,
transfer case or power transfer unit
failure.
Note: Do not use snow chains on vehicles
with 20 inch wheels and tires.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
Follow these guidelines when using snow
tires and chains:
If possible, avoid fully loading your
vehicle
Use only SAE Class S chains.
Install chains securely, verifying that
the chains do not touch any wiring,
brake lines or fuel lines.
Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure Monitoring
System
WARNING: The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury.
Check each tire, including the
spare, if provided, monthly when
cold and inflated 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 pressure 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 causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicles handling and stopping ability.
