Leaving the Vehicle With the Engine
Running
{CAUTION:
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 rmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch re. 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 rmly set before you leave it. SeeParking Brake
on page 2-32for more information.
Torque Lock
Torque 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 nd 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 Park
Automatic Transmission Shift Lock
This 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 or
ACC/ACCESSORY and the regular brake pedal
is applied.

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 5-103.
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 time the brakes are applied, with or without the
vehicle moving, the brakes adjust for wear.
Replacing Brake System Parts
The 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.

A ve-tire rotation pattern may be used for your
professional vehicle, if it has a full-size spare tire
and wheel assembly that matches the original
equipment tires and wheels in size, type and brand.
The correct ve-tire rotation pattern is shown.
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 4-19.Vehicles that have the Tire Pressure Monitor
System (TPMS) will need to have the sensors
reset after a tire rotation is performed. See
Tire Pressure Monitor System on page 5-60.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specifications on page 5-103.
{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 5-74.Five-Tire Rotation Pattern

13. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
{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 5-103for 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 5-103for the wheel nut torque specication.
