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 moving less than 5 mph (8 km/h), the
Exhaust Brake Indicator 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 characteristics 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
You must press and hold the brake pedal while
shifting out of PARK.
CAUTION!
Use of aftermarket exhaust brakes is not recom
-
mended and could lead to engine damage.
WARNING!
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.
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 indi
-
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
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, turn the engine OFF, and remove the
key fob. When the ignition is in the LOCK/OFF
(key removal) position, (or, with Keyless Enter
‘n Go™, when the ignition is in the OFF posi
-
tion) the transmission is locked in PARK,
securing the vehicle against unwanted move
-
ment.
When leaving the vehicle, always make sure
the ignition is in the OFF position, remove the
key fob from the vehicle, and lock the vehicle.
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 gear selector out of PARK with the
brake pedal released. Make sure the trans
-
mission is in PARK before exiting the vehicle.
