Note:A clear gel-like substance in the hydraulic brake master cylinder
reservoir may appear on some vehicles. This substance is a silicone base
lubricant used during assembly of the master cylinder. It will float on top
of the brake hydraulic fluid in the master cylinder. This condition is
normal and in no way affects the operation of the brake system. It does
not require any service.
Brake system fluid should be replaced on a regular basis to maintain
optimum braking performance, especially under heavy-duty driving
conditions such as frequent steep grades or heavy towing loads. Refer to
scheduled maintenance informationfor the service interval schedules.

•Avoid potholes and objects on the road
•Do not run over curbs or hit the tire against a curb when parking
Highway Hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
If you feel a sudden vibration or ride disturbance while driving, or you
suspect your tire or vehicle has been damaged, immediately reduce your
speed. Drive with caution until you can safely pull off the road. Stop and
inspect the tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you’re driving, the wheels may be
out of alignment. Have an authorized dealer check the wheel alignment
periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by an authorized dealer.
Front-wheel drive vehicles and those with an independent rear
suspension (if equipped) may require alignment of all four wheels.
The tires should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
Tire Rotation
Note:If your tires show uneven wear ask an authorized dealer to check
for and correct any wheel misalignment, tire imbalance or mechanical
problem involved before tire rotation.
Note:Your vehicle may be equipped with a dissimilar spare tire and
wheel assembly. A dissimilar spare tire and wheel assembly is defined as
a spare tire or wheel that is different in brand, size or appearance from
the road tires and wheels. If you have a dissimilar spare tire and wheel
assembly, it is intended for temporary use only and should not be used
in a tire rotation.
Rotating your tires at the recommended interval (as indicated in your
scheduled maintenance) will help your tires wear more evenly, providing
better tire performance and longer tire life.

When driving with the full-size dissimilar spare tire and wheel assembly,
additional caution should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire and wheel,
and seek service as soon as possible.
Tire Change Procedure
WARNING:When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission selector lever is in
positionP.
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure to place the transmission selector lever in
positionP, set the parking brake and block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
WARNING:Never get underneath a vehicle that is supported
only by a jack. If the vehicle slips off the jack, you or someone
else could be seriously injured.
WARNING:Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack or changing the
wheel.
WARNING:Always use the jack provided as original equipment
with your vehicle. If using a jack other than the one provided as
original equipment with your vehicle, make sure the jack capacity is
adequate for the vehicle weight, including any vehicle cargo or
modifications.
