Parking Brake Release
When the parking brake is applied with the ignition
switch ON, the "Brake Warning Light" in the instrument
cluster will illuminate.
NOTE:
When the parking brake is applied and the transmis-
sion is placed in gear, the "Brake Warning Light" will
flash. If vehicle speed is detected, a chime will
sound to alert the driver. Fully release the parking
brake before attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking
brake before placing the gear selector in PARK, other-
wise the load on the transmission locking mechanism
may make it difficult to move the gear selector out of
PARK. The parking brake should always be applied
whenever the driver is not in the vehicle.
WARNING!
Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement
and possible injury or damage.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving unattended
children in a vehicle is dangerous for a number of
reasons. A child or others could be seriously or
fatally injured.
Do not leave the key fob in or near the vehicle, or
in a location accessible to children, and do not
leave a vehicle equipped with Keyless Enter-N-Go
in the ACC or ON/RUN mode. A child could operate
power windows, other controls, or move the
vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to brake
failure and a collision.
Always fully apply the parking brake when leaving
your vehicle or it may roll and cause damage or
injury. Also, be certain to leave the transmission in
PARK. Failure to do so may cause the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with
the parking brake released, a brake system malfunc-
tion is indicated. Have the brake system serviced by
an authorized dealer immediately.
STARTING AND OPERATING
DIESEL EXHAUST BRAKE — ENGINE
BRAKING (IF EQUIPPED)
The purpose of the exhaust brake (engine braking) fea-
ture is to supply negative (braking) torque from the
engine. Typically, the engine braking is used for, but not
limited to, vehicle towing applications where vehicle
braking can be achieved by the internal engine power,
thereby sparing the mechanical brakes of the vehicle.
Benefits of the exhaust brake are:
Vehicle driving control.
Reduced brake fade.
Longer brake life.
Faster cab warm-up.
The exhaust brake feature will only function when the
driver toggles it on by pushing the exhaust brake button
until the "Exhaust Brake Indicator" is illuminated. Nor-
mal (Full Strength) exhaust brake mode is indicated by
a yellow "Exhaust Brake Indicator".
