3. If the gear selector is not in PARK, the ENGINE START/STOP button must be held for two seconds or three short
pushes in a row with the vehicle speed above 5 mph
(8 km/h) before the engine will shut off. The ignition
switch position will remain in the ACC position until the
gear selector is in PARK and the button is pushed twice
to the OFF position. If the gear selector is not in PARK
and the ENGINE START/STOP button is pushed once,
the instrument cluster display will display a “Vehicle
Not In Park” message and the engine will remain
running. Never leave a vehicle out of the PARK position,
or it could roll.
4. If the gear selector is in NEUTRAL, push and release the ENGINE START/STOP button with the vehicle speed
below 5 mph (8 km/h) before the engine will shut off.
The ignition will remain in the ACC position. NOTE:
If the ignition is left in the ACC or RUN (engine not
running) position and the transmission is in PARK, the
system will automatically time out after 30 minutes of
inactivity and the ignition will switch to the OFF position.
ENGINE START/STOP Button Functions — With
Driver ’s Foot OFF The Brake Pedal (In PARK Or
NEUTRAL Position)
The ENGINE START/STOP button operates similar to an
ignition switch. It has three positions, OFF, ACC, RUN. To
change the ignition switch positions without starting the
vehicle and use the accessories follow these steps:
1. Starting with the ignition in the OFF position:
2. Push the ENGINE START/STOP button once to change the ignition to the ACC position.
3. Push the ENGINE START/STOP button a second time to change the ignition to the RUN position.
4. Push the ENGINE START/STOP button a third time to return the ignition to the OFF position.

Keyless Enter-N-Go Starting Procedure — Engine
Manifold Air Temperature 0° F To 66° F (–18° C to
19° C)
NOTE:The temperature displayed in the instrument clus-
ter does not necessarily reflect the engine manifold air
temperature. Refer to “Instrument Cluster Display” in
“Understanding Your Instrument Panel” for further infor-
mation. When engine temperatures fall below 66°F (19°C)
the “Wait To Start Light” will remain on indicating the
intake manifold heater system is active.
Follow the steps in the “Normal Starting” procedure
except:
1. Pushing the engine start button with the driver ’s foot on the brake will move the ignition from OFF or ACC to
RUN, and will illuminate the Wait To Starttelltale. The
engine will not immediately crank, this is normal op-
eration.
2. The “Wait To Start telltale will remain on for a period of
time that varies depending on the engine temperature. 3. While the
Wait to Start telltale is on, the instrument
cluster will additionally display a gauge or bar whose
initial length represents the full Wait to Starttime
period. Its length will decrease until it disappears when
the Wait to Start time has elapsed.
CAUTION!
If the “Water in Fuel Indicator Light” remains on, DO
NOT START engine before you drain the water from
the fuel filters to avoid engine damage. Refer to
“Maintenance Procedures/Draining Fuel/Water Sepa-
rator Filter” in “Maintaining Your Vehicle” for further
information.
4. After the engine “Wait To Start” telltale goes off, the engine will automatically crank.
CAUTION!
The engine may automatically crank when the “Wait
To Start” time has elapsed. To abort the automatic
starting process, ensure the driver ’s foot is fully re-
moved from the brake pedal prior to pushing the
START/STOP button to cycle the ignition off.

pressure from the accelerator pedal. Exhaust braking is
most effective when the engine RPM is higher. The auto-
matic transmission will downshift more aggressively in
TOW/HAUL mode when the exhaust brake is enabled to
increase brake performance.
CAUTION!
Use of aftermarket exhaust brakes is not recommended
and could lead to engine damage
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.
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 (Auto)
Automatic Exhaust Brake technology delivers smoother,
less aggressive exhaust braking characteristics during
downhill descents. Although it can apply full exhaust
braking force if needed, Automatic Exhaust Brake may not
apply obvious braking if the vehicle speed is not increas-
ing. Automatic Exhaust Brake is intended to maintain
vehicle speed, while Full Exhaust Brake is intended to
reduce vehicle speed.
Automatic Exhaust Brake can be enabled by pushing the
exhaust brake button 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 Exhaust Brake is
enabled. Pushing the exhaust brake button again will
toggle the exhaust brake mode to off.
