If Engine Fails To Start
WARNING!
• Never pour fuel or other flammable liq-
uid into the throttle body air inlet open-
ing in an attempt to start the vehicle.
This could result in flash fire causing
serious personal injury.
• Do not attempt to push or tow your
vehicle to get it started. Vehicles
equipped with an automatic transmis-
sion cannot be started this way. Un-
burned 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 Procedure” in “In
Case Of Emergency” for further informa-
tion.Without Tip Start — Manual Transmission Only
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme
Cold Weather” procedures, it may be flooded.
Push the accelerator pedal all the way to the
floor and hold it there while cranking the
engine. This should clear any excess fuel in
case the engine is flooded.
CAUTION!
To prevent damage to the starter, do not
crank the engine for more than 15 seconds
at a time. Wait 10 to 15 seconds before
trying again.
If the engine has been flooded, it may start to
run, but not have enough power to continue
running when the key is released. If this
occurs, continue cranking with the accelera-
tor pedal pushed all the way to the floor.
Release the accelerator pedal and the key
once the engine is running smoothly.If the engine shows no sign of starting after
two 15-second periods of cranking with the
accelerator pedal held to the floor, repeat the
“Normal Starting” or “Extreme Cold
Weather” procedures.
With Tip Start — Automatic Transmission Only
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme
Cold Weather” procedures, it may be flooded.
To clear any excess fuel, push the accelerator
pedal all the way to the floor and hold it.
Then, turn the ignition switch to the START
position and release it as soon as the starter
engages. The starter motor will disengage
automatically in 10 seconds. Once this oc-
curs, release the accelerator pedal, turn the
ignition switch to the LOCK position, wait
10 to 15 seconds, then repeat the “Normal
Starting” procedure.
CAUTION!
To prevent damage to the starter, wait
10 to 15 seconds before trying again.
STARTING AND OPERATING

Possible Reasons The Engine Does Not
AUTO STOP
Prior to engine shut down, the system will
check many safety and comfort conditions to
see if they are fulfilled. In following situations
the engine will not stop:
• Driver’s seat belt is not buckled.
• Outside temperature is less than 1°F
(–17°C) or greater than 104°F (40°C).
• Actual cabin temperature is significantly
different than temperature set on Auto
HVAC.
• HVAC is set to full defrost mode.
• Engine has not reached normal operating
temperature.
• Battery discharged.
• When driving in REVERSE.
• Hood is open.
• Vehicle is in 4LO transfer case mode.It may be possible for the vehicle to be driven
several times without the STOP/START sys-
tem going into a STOP/START READY state
under more extreme conditions of the items
listed above.
To Start The Engine While In The STOP/
START AUTO STOP ACTIVE Mode
When the gear selector is in NEUTRAL, the
engine will start when the clutch pedal is
pressed. The vehicle will go into STOP/START
SYSTEM NOT READY mode until the vehicle
speed is greater than 3 mph (5 km/h).
Conditions that will cause the engine to start
automatically while in STOP/START AUTO STOP
ACTIVE mode
The Engine Will Start Automatically When:
• Actual cabin temperature is significantly
different than temperature set on Auto
HVAC.
• HVAC is set to full defrost mode.
• STOP/START AUTO STOP ACTIVE time ex-
ceeds 5 minutes.• Battery voltage drops too low.
• Low brake vacuum e.g. after several brake
pedal applications.
•
Vehicle is moving faster than 3 mph (5 km/h).
• STOP/START OFF switch is pressed.
• 4WD system is put into 4LO mode.
Conditions that force a manual key cycle
start while in STOP/START AUTO STOP AC-
TIVE mode:
The Engine Will Not Start Automatically If:
• The driver’s seatbelt was unbuckled
• The engine hood has been opened
• A STOP/START system error occurs
The engine may then only be restarted with
an ignition key cycle. The STOP/START KEY
START REQUIRED message will appear in
the instrument cluster under these condi-
tions. Refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”
for further information.

Wheel Lift Or Dolly TowFrontNOT ALLOWED
RearNOT ALLOWED
FlatbedALL BEST METHOD
Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
device to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN position, not the ACC
position.
If the vehicle's battery is discharged, refer to
“Gear Selector Override” in this section for
instructions on shifting the automatic trans-
mission out of PARK for towing.CAUTION!
• Do not use sling type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
• If the vehicle being towed requires steer-
ing, the ignition switch must be in the
ACC or ON/RUN mode, not in the LOCK/
OFF mode.
Without The Ignition Key
Special care must be taken when the vehicle
is towed with the ignition in the LOCK posi-
tion. The only approved method of towing
without the ignition key is with a flatbed
truck. Proper towing equipment is necessary
to prevent damage to the vehicle.
Four–Wheel Drive Models
The manufacturer recommends towing with
all wheelsOFFthe ground. Acceptable meth-
ods are to tow the vehicle on a flatbed or with
one end of the vehicle raised and the oppo-
site 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, withALL
wheels on the ground),IFthe transfer case is
inNEUTRAL(N) and the transmission is in
PARK(for automatic transmissions) or in gear
(NOTinNEUTRAL, for manual transmissions).
Refer to “Recreational Towing” in “Starting
And Operating” for detailed instructions.
CAUTION!
• Front or rear wheel lifts must not be used
(if the remaining wheels are on the
ground). Internal damage to the trans-
