STARTING AND OPERATING121
4WD LOW — If Equipped
AutoPark will be disabled when operating the vehicle in
4WD LOW.
The message “AutoPark Disabled ” will be displayed in the
instrument cluster.
Additional customer warnings will be given when both of
these conditions are met:
 Vehicle is not in PARK
 Driver’s door is ajar
The message “ AutoPark Not Engaged ” will be displayed in
the instrument cluster. A warning chime will continue until
you shift the vehicle into PARK or the driver’s door is
closed.
ALWAYS DO A VISUAL CHECK
that your vehicle is in PARK
by looking for the "P" in the instrument cluster display and
on the gear selector. As an added precaution, always apply
the parking brake when exiting the vehicle.
EXTENDED PARK STARTING
NOTE:Extended Park condition occurs when the vehicle has not
been started or driven for at least 30 days.

1. Install a battery charger or jumper cables to the battery to ensure a full battery charge during the
crank cycle.

2. Press and hold the brake pedal while pushing the ENGINE START/STOP button once.
3. If the engine fails to start within 10 seconds, wait 10 to 15 seconds to allow the starter to cool, then
repeat the Extended Park Starting procedure.
4. If the engine fails to start after eight attempts, allow the starter to cool for at least 10 minutes, then repeat
the Extended Park Starting procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed the
“Normal Starting” procedure and has not experienced an
extended park condition as defined previously, it may be
flooded. Push the accelerator pedal all the way to the floor
and hold it there while the engine is cranking. This should
clear any excess fuel in case the engine is flooded.
The starter motor will engage automatically, run for
10 seconds, 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.
WARNING!
If vehicle speed is above 1.2 mph (1.9 km/h), the
transmission will default to NEUTRAL until the vehicle
speed drops below 1.2 mph (1.9 km/h). A vehicle left in
the NEUTRAL position can roll. As an added precaution,
always apply the parking brake when exiting the vehicle.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
WARNING!
 Never pour fuel or other flammable liquid into the
throttle body air inlet opening 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 trans -
mission 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
Úpage 301.
CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.

JUMP STARTING
If your vehicle has a discharged battery, it can be jump
started using a set of jumper cables and a battery in
another vehicle, or by using a portable battery booster
pack. Jump starting can be dangerous if done improperly,
so please follow the procedures in this section carefully.
NOTE:When using a portable battery booster pack, follow the
manufacturer's operating instructions and precautions.
PREPARATIONS FOR JUMP START
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.

Positive (+) Jump Starting Post

NOTE:The positive (+) battery post may be covered with a
protective cap. Lift up on the cap to gain access to the
positive battery post. Do not jump off fuses. Only jump
directly off positive post which has a positive (+) symbol on
or around the post.
See the following steps to prepare for jump starting:

1. Apply the parking brake, shift the automatic transmission into PARK (P) and turn the ignition OFF.

2. Turn off the heater, radio, and all electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the jumper cables’ reach, apply the
parking brake and make sure the ignition is OFF.
NOTE:Be sure that the disconnected cable ends do not touch
each other, or either vehicle, until properly connected for
jump starting.
WARNING!
Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than
12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
WARNING!
Do not allow vehicles to touch each other as this could
establish a ground connection and personal injury
could result.

JUMP STARTING PROCEDURE
NOTE:Make sure at all times that unused ends of jumper cables
are not contacting each other or either vehicle while
making connections.
Connecting The Jumper Cables

1. Connect the positive
(+) end of the jumper cable to
the positive (+)
post of the discharged vehicle.

2. Connect the opposite end of the positive (+) jumper
cable to the positive (+) post of the booster battery.
3. Connect the negative (-) end of the jumper cable to
the negative (-) post of the booster battery.
4. Connect the opposite end of the negative (-) jumper
cable to a good engine ground. A “ground” is an
exposed metallic/unpainted part of the engine, frame
or chassis, such as an accessory bracket or large bolt.
The ground must be away from the battery and the
fuel injection system.

Jump Starting Label

5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then
start the engine in the vehicle with the discharged
battery.
6. Once the engine is started, see the following discon- necting procedure.
Disconnecting The Jumper Cables

1. Disconnect the negative
(-)
end of the jumper cable
from the engine ground of the vehicle with the
discharged battery.

2. Disconnect the opposite end of the negative (-)
jumper cable from the negative (-) post of the booster
battery.
WARNING!
 Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
 Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
 Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
WARNING!
Failure to follow this jump starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury.
CAUTION!
Do not run the booster vehicle engine above
2,000 RPM since it provides no charging benefit,
wastes fuel, and can damage booster vehicle engine.

3. Disconnect the positive (+) end of the jumper cable
from the positive (+) post of the booster battery.
4. Disconnect the opposite end of the positive (+)
jumper cable from the positive (+) post of the
discharged vehicle.
5. Reinstall the protective cover over the positive (+)
post of the discharged vehicle.
If frequent jump starting is required to start your vehicle
have the battery and charging system tested at an
authorized dealer.
REFUELING IN EMERGENCY
The vehicle is equipped with a refueling funnel for a
Cap-Less Fuel System, which is located with the jack and
tools
Úpage 294. If refueling is necessary, while using an
approved gas can, please insert the refueling funnel into
the filler neck opening.
NOTE:In certain cold conditions, ice may prevent the fuel door
from opening. If this occurs, lightly push around the
perimeter of the fuel door to break the ice buildup and
re-release the fuel door by pushing on the rear outer edge
near the center to unlatch. Do not pry on the door.

Refueling Funnel Location

Emergency Gas Can Refueling
Most gas cans will not open the flapper doors. A funnel is
provided to allow emergency refueling with a gas can.
See the following steps for refueling:

1. Retrieve funnel from the rear cargo storage area.

2. Insert funnel into same filler pipe opening as the fuel nozzle.

Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.
CAUTION!
Accessories plugged into the vehicle power outlets draw
power from the vehicle’s battery, even when not in use
(i.e., cellular devices, etc.). Eventually, if plugged in long
enough without engine operation, the vehicle’s battery
will discharge sufficiently to degrade battery life and/or
prevent the engine from starting.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off” the
fuel tank after filling.
