STARTING AND OPERATING
Once the "Exhaust Brake Indicator" is illuminated and
the vehicle is moving faster than 5 mph (8 km/h); the
exhaust brake will automatically operate when the
driver removes pressure from the accelerator pedal.
Exhaust braking is most effective when the engine RPM
is higher. The automatic transmission will downshift
more aggressively in TOW/HAUL mode when the
exhaust brake is enabled to increase brake
performance.
WARNING!
Do not use the exhaust brake feature when driving in
icy or slippery conditions as the increased engine
braking can cause the rear wheels to slide and the
vehicle to swing around with the possible loss of
vehicle control, which may cause an accident possibly
resulting in personal injury or death.
CAUTION!
Use of aftermarket exhaust brakes is not recom-
mended and could lead to engine damage
NOTE:
For optimum braking power it is recommended to use
the exhaust brake while in TOW/HAUL mode.
The exhaust brake feature can also be used to reduce
the engine warm up time. To use the exhaust brake as
a warm-up device, the vehicle must be stopped or mov-
ing less than 5 mph (8 km/h), the "Exhaust Brake Indi-
cator" must be on, and the coolant temperature must
be below 180°F (82°C) and ambient temperature
below 60°F (16°C).
Automatic "Smart" Exhaust Brake
Automatic "Smart" Exhaust Brake technology delivers
smoother, less aggressive exhaust braking characteris-
tics during downhill descents. Although it can apply full
exhaust braking force if needed, Automatic "Smart"
Exhaust Brake may not apply obvious braking if the
vehicle speed is not increasing. Automatic "Smart"
Exhaust Brake is intended to maintain vehicle speed,
while Full Exhaust Brake is intended to reduce vehicle
speed.
Automatic "Smart" Exhaust Brake can be enabled by
pushing the exhaust brake button (on the center stack)
again anytime after the normal Full Exhaust Brake has
been turned on. The "Exhaust Brake Indicator" in the
instrument cluster display will change from Yellow to
Green when Automatic "Smart" Exhaust Brake is
enabled. Pushing the exhaust brake button again will
toggle the exhaust brake mode to off.
AUTOMATIC TRANSMISSION
WARNING!
•
Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
•
Your vehicle could move and injure you and others
if it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission
is in PARK before exiting the vehicle.
•
The transmission may not engage PARK if the
vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator sol-
idly indicates PARK (P) without blinking. Ensure
that the vehicle is completely stopped, and the
PARK position is properly indicated, before exiting
the vehicle.
•
It is dangerous to shift out of PARK or NEUTRAL if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and
hit someone or something. Only shift into gear
when the engine is idling normally and your foot is
firmly pressing the brake pedal.
•
Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles,
you should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF mode, the
transmission is locked in PARK, securing the
vehicle against unwanted movement.
•
When exiting the vehicle, always make sure the
ignition is in the OFF mode, remove the key fob
from the vehicle, and lock the vehicle.
•
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a num-
ber of reasons. A child or others could be seriously
or fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the trans-
mission gear selector.
