Do NOT Grab The Door Handle When Locking
NOTE:
• After pushing the door handle lock button, you must wait two seconds before you can lock or unlock the doors, using
either Passive Entry door handle. This is done to allow you
to check if the vehicle is locked by pulling the door handle,
without the vehicle reacting and unlocking.
• The Passive Entry system depends on a key fob that is not fully discharged of its coin battery capacity.
• The LED light on the key fob will not blink if the key fob battery is low or fully depleted, but a low key fob battery
condition will still support the Passive Entry system func -tionality. When the key fob battery is low, the instrument
cluster will display a message indicating that the key fob
battery is low. Refer to “Keys” in “Getting To Know Your
Vehicle” for further information.
The vehicle doors can also be locked by using the key fob
lock button or the lock button located on the vehicle’s inte -
rior door panel.

Some vehicles may be equipped with a rear cupholder that
consists of two cup wells for rear passenger convenience.Rear Cup WellsElectrical Power Outlets
The auxiliary 12 Volt (13 Amp) power outlet can provide
power for in-cab accessories designed for use with the stan -
dard “cigar lighter” plug. The 12 Volt power outlets and 5
Volt (2.5 Amp) USB Port (Charge Only) have a cap attached
to the outlet indicating “12V DC,” together with either a key
symbol, battery symbol, or USB symbol.
A key symbol indicates that the key must be in the ON/RUN
or ACC positions for the outlet to provide power. The battery
symbol indicates that the outlet is connected to the battery,
and can provide power at all times.
CAUTION!

• Do not exceed the maximum power of 160 Watts (13 Amps) at 12 Volts. If the 160 Watts (13 Amps) power rating is
exceeded, the fuse protecting the system will need to be
replaced.

• Power outlets are designed for accessory plugs only. Do not insert any other object in the power outlets as this
will damage the outlet and blow the fuse. Improper use
of the power outlet can cause damage not covered by
your New Vehicle Limited Warranty.

256 SAFETY
(Continued)
• Cut off battery power to the:•Engine
•Electric Motor (if equipped)
•Electric power steering
•Brake booster
•Electric park brake
•Automatic transmission gear selector
•Horn
•Front wiper
•Headlamp washer pump
NOTE:
After an accident, remember to cycle the ignition to the STOP
(OFF/LOCK) position and remove the key from the ignition
switch to avoid draining the battery. Carefully check the
vehicle for fuel leaks in the engine compartment and on the
ground near the engine compartment and fuel tank before
resetting the system and starting the engine. If there are no
fuel leaks or damage to the vehicle electrical devices (e.g.
headlights) after an accident, reset the system by following
the procedure described below. If you have any doubt,
contact an authorized dealer. Enhanced Accident Response System Reset Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be changed
from ignition START or ON/RUN to ignition OFF. Carefully
check the vehicle for fuel leaks in the engine compartment
and on the ground near the engine compartment and fuel
tank before resetting the system and starting the engine.
Maintaining Your Air Bag System
WARNING!
• Modifications to any part of the air bag system could cause it to fail when you need it. You could be injured
if the air bag system is not there to protect you. Do not
modify the components or wiring, including adding
any kind of badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the instru -
ment panel. Do not modify the front bumper, vehicle
body structure, or add aftermarket side steps or
running boards.
• It is dangerous to try to repair any part of the air bag system yourself. Be sure to tell anyone who works on
your vehicle that it has an air bag system.

296 STARTING AND OPERATING
accelerator pedal and the brake pedal, wait 10 to 15 seconds,
then repeat the “Normal Starting” procedure.If the engine has been flooded, it may start to run, but not
have enough power to continue running when the ignition
button/key is released. If this occurs, continue cranking with
the accelerator pedal pushed all the way to the floor. Release
the accelerator pedal and the ignition button/key once the
engine is running smoothly.
If the engine shows no sign of starting after a 10 second
period of engine cranking with the accelerator pedal held to
the floor, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
Cold Weather Operation (Below –22°F Or −30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
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 transmis -
sion 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
Procedure” in “In Case Of Emergency” for further
information.
CAUTION!
To prevent damage to the starter, do not crank the engine
for more than 10 seconds at a time. Wait 10 to 15 seconds
before trying again.

496 IN CASE OF EMERGENCY
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip-
ment designed for this purpose, following equipment manu-
facturer’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
brackets. State and local laws regarding vehicles under tow
must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode. If the key fob is unavailable or the vehicle's battery is
discharged, refer to ”Manual Park Release” in this section for
instructions on shifting the transmission out of PARK for
towing.
