If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in a flash fire causing serious per-
sonal injury.
• Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle. If the vehicle has a discharged
battery, booster cables may be used to
obtain a start from a booster battery or the
battery in another vehicle. This type of start
can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emer-
gencies” for further information. Clearing a Flooded Engine
(Using ENGINE START/STOP Button)
If the engine fails to start after you have fol-
lowed the “Normal Starting” or “Extreme Cold

procedures, it may be flooded. To
clear any excess fuel, press and hold the brake
pedal, push the accelerator pedal all the way to
the floor and hold it, then press and release the
ENGINE START/STOP button once. The starter
motor will engage automatically, run for 10 sec-
onds, and then disengage. Once this occurs,
release the accelerator pedal and the brake
pedal, wait 10 to 15 seconds, then repeat the
“Normal Starting” procedure.

AUTOMATIC TRANSMISSION
CAUTION!
Damage to the transmission may occur if the
following precautions are not observed:
•Shift into PARK only after the vehicle has
come to a complete stop.
• Shift into or out of REVERSE only after the
vehicle has come to a complete stop and
the engine is at idle speed.
• Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
• Before shifting into any gear, make sure
your foot is firmly pressing the brake pedal.
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
WARNING!
• 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 apply the parking brake,
shift the transmission into PARK, and re-
move the key fob. Once the key fob is
removed, the shift lever is locked in the
PARK position, securing the vehicle
against unwanted movement.
• It is dangerous to move the shift lever 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 re-
verse. You could lose control of the vehicle
and hit someone or something. Only shift
into gear when the engine is idling normally
and when your foot is firmly pressing the
brake pedal.
(Continued)WARNING!(Continued)
• When leaving the vehicle, always remove
the key fob and lock your vehicle.
• Never leave children alone in a vehicle, or
with access to an unlocked vehicle. Allow-
ing children to be in a vehicle unattended is
dangerous for a number of reasons. A child
or others could be seriously or fatally in-
jured.
• Children should be warned not to touch the
parking brake, brake pedal or the shift
lever. Do not leave the key fob in or near
the vehicle, and do not leave Keyless
Enter-N-Go in the ACC or ON/RUN mode.
A child could operate power windows, other
controls, or move the vehicle.
Key Ignition Park InterlockThis vehicle is equipped with a Key Ignition
Park Interlock which requires the shift lever to
be placed in PARK before the ignition switch
can be turned to the LOCK/OFF position. The
key fob can only be removed from the ignition
221

When parking on a hill, apply the parking brake
before placing the shift lever in PARK, other-
wise the load on the transmission locking
mechanism may make it difficult to move the
shift lever out of PARK. As an added precau-
tion, turn the front wheels toward the curb on a
downhill grade and away from the curb on an
uphill grade.
WARNING!
•Never use the PARK position as a substi-
tute for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible
injury or damage.
• Your vehicle could move and injure you and
others if it is not completely in PARK.
Check by trying to move the shift lever
rearward (with the brake pedal released),
after you have placed it in PARK. Make
sure the transmission is in PARK before
leaving the vehicle.

ELECTRONIC BRAKE CONTROL
SYSTEM
Your vehicle is equipped with an advanced
electronic brake control system that includes
the Anti-Lock Brake System (ABS), Traction
Control System (TCS), Brake Assist System
(BAS), Electronic Roll Mitigation (ERM), and
Electronic Stability Control (ESC). All five of
these systems work together to enhance ve-
hicle stability and control in various driving
conditions.
Also, your vehicle is equipped with Trailer Sway
Control (TSC), Hill Start Assist (HSA), Brake
Lock Differential (BLD), Ready Alert Braking,
Rain Brake Support and, if it has four-wheel
drive with the MP 3023 two-speed transfer
case, Hill Descent Control (HDC).
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining ve-
hicle control under adverse braking conditions.
The system controls hydraulic brake pressure
to prevent wheel lock-up and help avoid skid-
ding on slippery surfaces during braking.

Towing Without The Ignition Key
Fob
Special care must be taken when the vehicle is
towed with the ignition in the LOCK/OFF posi-
tion. The only approved method of towing with-
out the ignition key is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Four-Wheel Drive VehiclesThe manufacturer recommends towing with all
wheelsOFFthe ground. Acceptable methods
are to tow the vehicle on a flatbed or with one
end of vehicle raised and the opposite end on
a towing dolly.
If flatbed equipment is not available, and the
transfer case is operable, the vehicle may be
towed (in the forward direction, with ALL
wheels on the ground), IFthe transfer case is in
NEUTRAL and the transmission is in PARK.
Refer to “Recreational Towing” in “Starting And
Operating” for detailed instructions.CAUTION!
• Front or rear wheel lifts should not be used.
Internal damage to the transmission or
transfer case will occur if a front or rear
wheel lift is used when towing.
• Failure to follow these towing methods can
cause severe damage to the transmission
and/or transfer case. Such damage is not
covered by the New Vehicle Limited War-
ranty.
