Torque Lock (Automatic Transmission)
If you are parking on a hill and you do not shift your
transmission into P (Park) properly, the weight of
the vehicle may put too much force on the parking pawl
in the transmission. You may nd it difficult to pull the
shift lever out of P (Park). This is called “torque lock.”
To prevent torque lock, set the parking brake and
then shift into P (Park) properly before you leave the
driver seat. To nd out how, seeShifting Into Park
(Automatic Transmission) on page 2-29.
When you are ready to drive, move the shift lever out
of P (Park) before you release the parking brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to take
some of the pressure from the parking pawl in the
transmission, so you can pull the shift lever out
of P (Park).
Shifting Out of Park
Vehicles with an automatic transmission have a shift
interlock system. You have to apply the brake pedal
before you can shift from P (Park) when the ignition is
in the ON/RUN position. SeeAutomatic Transmission
Operation on page 2-22.
If you cannot shift out of P (Park) while holding the
brake pedal down, try this:
1. Set the parking brake.
2. Turn the ignition off and remove the key.
3. Remove the hole cover from the shift lock slot by
prying it off using a small, at object. The shift
lock release slot is located at the top of the
shift lever.

Brake Wear
This vehicle has front disc brakes and could have rear
drum brakes or rear disc brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are
worn and new pads are needed. The sound can come
and go or be heard all the time the vehicle is moving,
except when applying the brake pedal rmly.
{CAUTION:
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 rst 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 specications inCapacities
and Specifications on page 5-93.If the vehicle has rear drum brakes, they do not have
wear indicators, but if a rear brake rubbing noise is
heard, have the rear brake linings inspected
immediately. Rear brake drums should be removed and
inspected each time the tires are removed for rotation
or changing. When the front brake pads are replaced,
have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See 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 Adjustment
Every moderate brake stop, the disc brakes adjust for
wear. If rarely making moderate or heavier brake stops,
the brakes might not adjust correctly. Very carefully
making a few moderate brake stops about every
1,000 miles (1 600 km) will adjust the brakes properly.
If the vehicle has rear drum brakes and the brake pedal
goes down farther than normal, the rear drum brakes
might need adjustment. Adjust them by backing up and
rmly applying the brakes a few times.

After the tires have been rotated, adjust the front
and rear ination pressures as shown on the
tire and loading information label. SeeLoading the
Vehicle on page 4-16for an example of the tire
and loading information label and where it is
located on your vehicle. Make certain that all wheel
nuts are properly tightened. See “Wheel Nut
Torque” underCapacities and Specifications on
page 5-93.
{CAUTION:
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. See
Changing a Flat Tire on page 5-70.
When It Is Time for New Tires
Various factors, such as maintenance, temperatures,
driving speeds, vehicle loading, and road conditions
inuence when you need new tires.
One way to tell when it is
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of tread
remaining.
You need new tires if any of the following statements
are true:
You can see the indicators at three or more places
around the tire.
You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut, or snagged
deep enough to show cord or fabric.

{CAUTION:
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 specication
after replacing. Follow the torque specication
supplied by the aftermarket manufacturer when
using accessory locking wheel nuts. SeeCapacities
and Specifications on page 5-93for original
equipment wheel nut torque specications.
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 specication. SeeCapacities and
Specifications on page 5-93for the wheel nut
torque specication.16. Tighten the wheel nuts
rmly in a crisscross
sequence, as shown.
Notice:Wheel covers will not t on your vehicle’s
compact spare. If you try to put a wheel cover
on the compact spare, the cover or the spare could
be damaged.
