WARNING!
To avoid serious injury or death:
Only devices designed for use in this type of
outlet should be inserted into any 12 Volt
outlet.
Do not touch with wet hands.
Close the lid when not in use and while
driving the vehicle.
If this outlet is mishandled, it may cause an
electric shock and failure.
CAUTION!
Many accessories that can be plugged in
draw power from the vehicle's battery, even
when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the
vehicle's battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.
All accessories connected to the “battery”
powered outlets should be removed or
turned off when the vehicle is not in use.
Leaving devices connected overnight will
drain the vehicle’s battery.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.) will
degrade the battery even more quickly.
Only use these intermittently and with
greater caution.
WARNING! (Continued)
After the use of high power draw accesso -
ries, or long periods of the vehicle not being
started (with accessories still plugged in),
the vehicle must be driven a sufficient
length of time to allow the generator to
recharge the vehicle's battery.
CAUTION! (Continued)

STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts.
Automatic Transmission
The gear selector must be in the PARK (P) or
NEUTRAL (N) position before you can start the
engine. Press the brake pedal before shifting to
any driving gear.
NOTE:
You must press the brake pedal before shifting
out of PARK.
Normal Starting
Turn the ignition switch to the AVV (START)
position and release it when the engine starts.
If the engine fails to start within 10 seconds,
turn the ignition switch to the STOP (OFF/LOCK)
position, wait 10 to 15 seconds, then repeat
this procedure.
Cold Weather Operation
To ensure reliable starting at low temperatures,
use of an externally powered electric engine
block heater (available from an authorized
dealer) is recommended.To prevent possible engine damage while
starting at low temperatures, this vehicle will
inhibit engine cranking when the ambient
temperature is less than -31°F (-35° C) and the
oil temperature sensor reading indicates an
engine block heater has not been used. The
message “plug in engine heater” will be
displayed in the instrument cluster when the
ambient temperature is below -25°F (-32° C) at
the time the engine is shut off as a reminder.
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. Place the ignition in the AVV (START) position and release it when the engine
starts.
WARNING!
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren). A child could operate power
windows, other controls, or move the
vehicle.

STARTING AND OPERATING59
3. If the engine fails to start within ten
seconds, place the ignition in the STOP
(OFF/LOCK) position, wait five 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
procedure.
If Engine Fails To Start
If the engine fails to start after you have
followed the “Normal Starting” or “Extreme Cold
Weather” procedure, and has not experienced
an extended park condition as identified in
“Extended Park Starting” procedure, it may be
flooded. Push the accelerator pedal all the way
to the floor and hold it there. Crank the engine
for no more than 15 seconds. This should clear
any excess fuel in case the engine is flooded. Leave the ignition key in the MAR (ON/RUN)
position, release the accelerator pedal and
repeat the “Normal Starting” procedure.
After Starting
The idle speed is controlled automatically, and
it will decrease as the engine warms up.
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine and
permits quicker starts in cold weather.
Connect the cord to a 110-115 Volt AC electrical
outlet with a grounded, three-wire extension
cord.
For ambient temperatures below 0°F (-18°C),
the engine block heater is recommended. For
ambient temperatures below -20°F (-29°C),
the engine block heater is required.
The engine block heater cord is routed under
the hood, behind to the driver’s side headlamp.
Follow the steps below to properly use the
engine block heater:
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 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
Úpage 204.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than
25 seconds at a time. Wait 60 seconds
before trying again.
