Leaving the Vehicle With the Engine
Running
{
WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) with the parking
brake firmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch fire. You or others could be injured. Do not
leave the vehicle with the engine running.
If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is firmly set before you leave it. SeeParking Brake
on page 3-27for more information.
Torque LockTorque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then it
is difficult to shift out of P (Park). To prevent torque lock,
set the parking brake and then shift into P (Park). To find
out how, see “Shifting Into Park” in this section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).Shifting Out of ParkAutomatic Transmission Shift LockThe vehicle has an electronic shift lock release system.
The shift lock release is designed to:•
Prevent ignition key removal unless the shift lever is
in P (Park)
•
Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the regular
brake pedal is applied.

WARNING:
The brake wear warning sound means that soon
the brakes will not work well. That could lead to an
accident. When the brake wear warning sound is
heard, have the vehicle serviced.
Notice:Continuing to drive with worn-out brake
pads could result in costly brake repair.
Some driving conditions or climates can cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to torque specifications in
Capacities and Specifications on page 6-100.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal TravelSee your dealer/retailer if the brake pedal does not
return to normal height, or if there is a rapid increase in
pedal travel. This could be a sign that brake service
might be required.Brake AdjustmentEvery time the brakes are applied, with or without the
vehicle moving, the brakes adjust for wear.Replacing Brake System PartsThe braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. The vehicle
was designed and tested with top-quality brake parts.
When parts of the braking system are replaced — for
example, when the brake linings wear down and new
ones are installed — be sure to get new approved
replacement parts. If this is not done, the brakes might
not work properly. For example, if someone puts in
brake linings that are wrong for the vehicle, the balance
between the front and rear brakes can change — for the
worse. The braking performance expected can change in
many other ways if the wrong replacement brake parts
are installed.

When rotating the vehicle’s tires, always use the
correct rotation pattern shown here.
Do not include the compact spare tire in the tire
rotation.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the Tire
and Loading Information label. SeeInflation - Tire
Pressure on page 6-59andLoading the Vehicle on
page 5-20.Reset the Tire Pressure Monitor System. SeeTire
Pressure Monitor Operation on page 6-62.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 6-100.

WARNING:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the
vehicle. In an emergency, you can use a
cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if needed, to get all the rust or dirt off.
SeeChanging a Flat Tire on page 6-75.

10. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
{
WARNING:
Wheel nuts that are improperly or incorrectly
tightened can cause the wheels to become loose
or come off. The wheel nuts should be tightened
with a torque wrench to the proper torque
WARNING: (Continued)
WARNING: (Continued)specification after replacing. Follow the torque
specification supplied by the aftermarket
manufacturer when using accessory locking
wheel nuts. SeeCapacities and Specifications
on page 6-100for original equipment wheel nut
torque specifications.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque
specification. SeeCapacities and Specifications on
page 6-100for the wheel nut torque specification.
11. Tighten the wheel nuts
firmly in a crisscross
sequence as shown.
