sensors), the system wiring, the airbag system readiness light, the airbag
back-up power and the airbag ignitors.
Front passenger sensing system
The front passenger sensing system is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS) 208
and is designed to disable (will not inflate) the front passenger’s frontal
airbag under certain conditions.
The front passenger sensing system works with sensors that are part of
the front passenger’s seat and safety belt. The sensors are designed to
detect the presence of a properly seated occupant and determine if the
front passenger’s frontal airbag should be enabled (may inflate) or
disabled (will not inflate).
The front passenger sensing system will disable (will not inflate) the
front passenger’s frontal airbag if:
•the front passenger seat is unoccupied, or has small/medium objects in
the front seat.
•the system determines that an infant is present in a rear-facing infant
seat that is installed according to the manufacturer’s instructions.
•the system determines that a small child is present in a forward-facing
child restraint that is installed according to the manufacturer’s
instructions.
•the system determines that a small child is present in a booster seat.
•a front passenger takes his/her weight off of the seat for a period of
time.

The side airbag system consists of
the following:
•An inflatable bag (airbag) with a
gas generator concealed behind
the outboard bolster of the driver
and front passenger seatbacks.
•A special seat cover designed to
allow airbag deployment.
•The same warning light,
electronic control and diagnostic
unit as used for the front airbags.
•Two crash sensors mounted in the front doors (one on each side of
the vehicle).
•Crash sensors located on the C pillars (one sensor on each pillar on
each side of the vehicle).
Side airbags, in combination with safety belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side airbags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the airbag on the side affected by
the collision will be inflated. The airbag was designed to inflate between
the door panel and occupant to further enhance the protection provided
occupants in side impact collisions.
The airbag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates airbag inflation.
The fact that the airbags did not inflate in a collision does not mean that
something is wrong with the system. Rather, it means the forces were
not of the type sufficient to cause activation. Side airbags are designed
to inflate in side-impact collisions, not roll-over, rear-impact, frontal or
near-frontal collisions, unless the collision causes sufficient lateral
deceleration.
WARNING:Several air bag system components get hot after
inflation. Do not touch them after inflation.

How does the Safety CanopySystem work?
The design and development of the
Safety Canopy system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy).
The Safety Canopy system consists
of the following:
•An inflatable curtain with a gas
generator concealed behind the
headliner and above the doors
(one on each side of vehicle).
•A headliner designed to flex open above the side doors to allow Safety
Canopy deployment.
•The same readiness airbag light, electronic control and diagnostic unit
as used for the front airbags.
•Two crash sensors mounted in the front doors (one on each side of
the vehicle).
•Two crash sensors located at the C pillar behind the rear doors (one
on each side of the vehicle).
•Rollover sensor in the restraints control module (RCM).
The Safety Canopy system, in combination with safety belts, can help
reduce the risk of severe injuries in the event of a significant side impact
collision or rollover event.
Children 12 years old and under should always be properly restrained in
the second or third row seats. The Safety Canopy will not interfere with
children restrained using a properly installed child or booster seat
because it is designed to inflate downward from the headliner above the
doors along the side window opening.
The Safety Canopy system is designed to activate when the vehicle
sustains lateral deceleration sufficient to cause the side crash sensor to
close an electrical circuit that initiates Safety Canopy inflation or when a
certain likelihood of a rollover event is detected by the rollover sensor.

Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
WARNING:Do not connect a trailer’s hydraulic brake system
directly to your vehicle’s brake system. Your vehicle may not
have enough braking power and your chances of having a collision
greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking-up trailer lamps.
WARNING:Never connect any trailer lighting to the vehicle’s
tail lamp circuits, because it may damage the electrical system
resulting in fire. Contact your authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Driving while you tow
When towing a trailer:
•Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing and don’t make full-throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Activate the tow/haul feature or the grade assist feature on your
transmission to eliminate excessive transmission shifting and assist in
transmission cooling. For additional information, refer toAutomatic
transmission operationin theDrivingchapter.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.

Trailer towing tips
•Practice turning, stopping and backing-up before starting on a trip to
get the feel of the vehicle-trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
RECREATIONAL TOWING
Follow these guidelines for your specific powertrain combination to tow
your vehicle for personal travel (such as behind a motor home or a
truck).
Note:Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to theClimate
Controlschapter for more information.
In case of a roadside emergency with a disabled vehicle, please refer to
Wrecker towingin theRoadside Emergencieschapter.
These guidelines are designed to prevent damage to your vehicle after it
is hooked-up to the RV or tow dolly.
Front-wheel drive (FWD) vehiclescan be towed with all four wheels
on the ground or with the front wheels off the ground by using a tow
dolly. If you are using a tow dolly follow the instructions specified by the
equipment provider. If you are towing with all four wheels on the ground,
refer to the towing instructions found at the end of this section.
Four-wheel drive (4WD) vehiclescan be towed with all four wheels
on the ground or with all four wheels off the ground using a vehicle
transport trailer.Do not tow your 4WD vehicle with the front
wheels off the ground (by using a tow dolly) and the rear wheels
on the ground; this will cause damage to your 4WD system.If you
are using a vehicle transport trailer, follow the instruction specified by
the equipment provider. If you are towing with all four wheels on the
ground, refer to the towing instructions found at the end of this section.

STARTING
Positions of the ignition (if equipped)
If your vehicle is equipped with a push button start system, refer to
Push button start systemin this section for ignition modes.
1. Off— locks the gearshift lever
and allows key removal. This
position also shuts the engine and
all electrical accessories off.
Note:In order to switch off the
engine while the vehicle is in
motion, shift to neutral and use the
brakes to bring the vehicle to a safe
stop. After the vehicle has stopped, turn the engine off and shift into
park. Then turn the key to the accessory or off position.
2. Accessory— allows the electrical accessories such as the radio to
operate while the engine is not running.
3. On— all electrical circuits operational. Warning lights illuminated. Key
position when driving.
4. Start— cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system.
This system meets all Canadian interference-causing equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, don’t press the accelerator before
or during starting. Only use the accelerator when you have difficulty
starting the engine. For more information on starting the vehicle, refer to
Starting the enginein this chapter.
WARNING:Extended idling at high engine speeds can produce
very high temperatures in the engine and exhaust system,
creating the risk of fire or other damage.
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.

WARNING:Do not start your vehicle in a closed garage or in
other enclosed areas. Exhaust fumes can be toxic. Always open
the garage door before you start the engine. SeeGuarding against
exhaust fumesin this chapter for more instructions.
WARNING:If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Important safety precautions
When the engine starts, the idle RPM runs faster to warm the engine. If
the engine idle speed does not slow down automatically, have the vehicle
checked.
If the vehicle is operated in a heavy snow storm or blowing snow
conditions, the engine air induction may become partially clogged with
snow and/or ice. If this occurs the engine may experience a significant
reduction in power output. At the earliest opportunity, clear all snow
and/or ice away for the air induction inlet.
Before starting the vehicle:
1. Make sure all occupants buckle their safety belts. For more
information on safety belts and their proper usage, refer to theSeating
and Safety Restraintschapter.
2. Make sure the headlamps and electrical accessories are off.

3. After idling for a few seconds, release the parking brake, apply the
brake, shift into gear and drive.
Note:If the engine does not start on the first try, turn the vehicle to the
off position, wait 10 seconds and try Step 2 again. If the engine still fails
to start, press the accelerator to the floor and try Step 2 again, keeping
the accelerator on the floor until the engine begins to accelerate above
cranking speeds; this will allow the engine to crank with the fuel shut off
in case the engine is flooded with fuel.
Push button start system (if equipped)
If your vehicle is equipped with the
push button start system, you can
start your vehicle by pressing the
start button in combination with the
brake pedal rather than using a key.
The start button is located on the
instrument panel to the right of the
steering wheel.
In order to operate the push button
start system and start the vehicle,
your intelligent access key (IA key)
must be present inside the vehicle.
Ignition modes
1. Off — press and release the START/STOP button without applying the

applying the brake pedal.Note:The indicator light on the start button
will illuminate when the vehicle is in on mode and when the engine is
started.
There may be areas inside your vehicle where the IA key is not detected.
If the message NO KEY DETECTED appears on your message center
when you press the START/STOP button, it may be necessary to move
your IA key to another area within the vehicle. The IA key may not be
detected near the roof (between the driver or passenger sunvisor and
the roof, or in the overhead console area) or in the extreme corners of
the rear package tray, near your audio speakers. It is not recommended
that you stow the IA key in these locations. If you move the IA key to a
location where it has been detected before and you still see the NO KEY
DETECTED message, your IA key’s battery may be low or you may be in
an area with excessive radio frequency interference. If this occurs, you
can use the back-up method to start your vehicle (see below).
Back-up method of starting:Your IA key uses a radio frequency signal
to communicate with your vehicle and authorize your vehicle to start
when you press the START/STOP button and apply the brake pedal. If
excessive radio frequency interference is present in the area, or if the
battery in your IA key is low, it may be necessary to start your car by
inserting the IA key in the back-up slot, located at the front of the center
console storage compartment. Insert the IA key into the slot with
buttons facing out and with key ring up. After inserting the IA key into
the back-up slot, use the START/STOP button and brake pedal to start
your vehicle as usual. The vehicle should respond normally as long as the
IA key is in the back-up slot. Once the vehicle is started, the IA key can
be removed from the back-up slot, if desired.
Fast restart feature:The fast restart feature allows you to re-start
your vehicle within 20 seconds of switching the vehicle off, if a valid IA
key is not present when the vehicle is switched off. When you switch
your vehicle off without an IA key in the passenger compartment or
trunk, the message RESTART NOW OR KEY IS NEEDED will be
displayed in the message center. You can re-start the vehicle (by
applying the brake pedal and pressing the START/STOP button) for up
to 20 seconds, even though the IA key is not present. After 20 seconds
have expired, you can no longer start your vehicle without the IA key
present inside the vehicle.

ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
WARNING:Failure to follow engine block heater instructions
could result in property damage or physical injury.
WARNING:To reduce the risk of electrical shock, do not use
your heater with ungrounded electrical systems or two-pronged
(cheater) adapters.
Prior to using the engine block heater, follow these recommendations for
proper and safe operation:
•For your safety, use an outdoor extension cord that is product
certified by Underwriter’s Laboratory (UL) or Canadian Standards
Association (CSA). Use only an extension cord that can be used
outdoors, in cold temperatures, and is clearly marked “Suitable for Use
with Outdoor Appliances.” Never use an indoor extension cord
outdoors; it could result in an electric shock or fire hazard.
•Use a 16-gauge outdoor extension cord, minimum.
•Use as short an extension cord as possible.
•Do not use multiple extension cords. Instead, use one extension cord
which is long enough to reach from the engine block heater cord to
the outlet without stretching.
•Make certain that the extension cord is in excellent condition (not
patched or spliced). Store your extension cord indoors at
temperatures above 32°F (0°C). Outdoor conditions can deteriorate
extension cords over a period of time.
•To reduce the risk of electrical shock, do not use your heater with
ungrounded electrical systems or two pronged (cheater) adapters.
Also ensure that the block heater, especially the cord, is in good
condition before use.
•Make sure that when in operation, the extension cord plug/engine
block heater cord plug connection is free and clear of water in order
to prevent possible shock or fire.
