Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.
Hitches
Do not use a hitch that clamps onto the vehicle’s bumper or attaches to
the axle. You must distribute the load in your trailer so that 10–15% of
the total weight of the trailer is on the tongue.

Using a step bumper (if equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a one inch (25.4 mm) shank diameter. The bumper has a
5,000 lb (2,270 kg) trailer weight and 500 lb (227 kg) tongue weight
capacity.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
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 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.
If your vehicle is equipped with AdvanceTracwith RSC, you may
experience AdvanceTracwith RSC activations during typical cornering
maneuvers with a heavily loaded trailer; this is normal. Cornering at a
slower speed while towing will reduce the tendency of the AdvanceTrac
stability enhancement system to activate.
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. Also, see the information on tow/haul mode operation
underAutomatic transmission operationin theDrivingchapter.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider

STARTING
Positions of the ignition
1. Off — locks the automatic
transmission gearshift lever and
allows key removal.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.
Note:The ignition key cannot be removed from the ignition unless the
gearshift lever is securely latched in P (Park).
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
A computer system controls the engine’s idle revolutions per minute
(RPM). When the engine starts, the idle RPM runs higher than normal in
order 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 from the air induction
inlet. Do not allow the vehicle to idle for more than 10 minutes at the
higher engine RPM.
Before starting the vehicle:
1. Make sure all vehicle occupants have buckled their safety belts. For
more information on safety belts and their proper usage, refer to the
Seating and Safety Restraintschapter.
2. Make sure the headlamps and vehicle accessories are off.

Starting the engine
1. Turn the key to 3 (on) without
turning the key to 4 (start).
2. Turn the key to 4 (start), then
release the key as soon as the
engine begins cranking. Your vehicle
has a computer assisted cranking
system that assists in starting the
engine. After releasing the key from
the 4 (start) position, the engine
may continue cranking for up to
10 seconds or until the vehicle
starts.
Note:Cranking may be stopped at any time by turning the key to the off
position.
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 key 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.
Cold weather starting (flexible fuel vehicles only)
The starting characteristics of all grades of E
85ethanol make it
unsuitable for use when ambient temperatures fall below 0°F (-18°C).
Consult your fuel distributor for the availability of winter grade ethanol.
As the outside temperature approaches freezing, ethanol fuel distributors
should supply winter grade ethanol (same as with unleaded gasoline). If
summer grade ethanol is used in cold weather conditions, 0°F to 32°F
(-18°C to 0°C), you may experience increased cranking times, rough idle
or hesitation until the engine has warmed up.
You may experience a decrease in peak performance when the engine is
cold when operating on E
85ethanol.
Do not crank the engine for more than 10 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to off and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system. Such
fluid could cause immediate explosive damage to the engine and possible
personal injury.

If you should experience cold weather starting problems on E85ethanol,
and neither an alternative brand of E
85ethanol nor an engine block
heater is available, the addition of unleaded gasoline to your tank will
improve cold starting performance. Your vehicle is designed to operate
on E
85ethanol alone, unleaded gasoline alone, or any mixture of the two.
SeeChoosing the right fuelin theMaintenance and Specifications
chapter for more information on ethanol.
If the engine fails to start using the preceding instructions
(flexible fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
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 ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 1 inch (2.5 cm) or adjust the heating or
air conditioning to bring in fresh air.
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).
For flexible fuel vehicles, if operating with E
85ethanol, an engine block
heater must be used if ambient temperature is below 0°F (-18°C).
SeeCold weather startingearlier in this chapter for more information
on starting with ethanol.

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.
•Be sure that areas where the vehicle is parked are clean and clear of
all combustibles such as petroleum products, dust, rags, paper and
similar items.
•Be sure that the engine block heater, heater cord and extension cord
are solidly connected. A poor connection can cause the cord to
become very hot and may result in an electrical shock or fire. Be sure
to check for heat anywhere in the electrical hookup once the system
has been operating for approximately a half hour.

•Finally, have the engine block heater system checked during your fall
tune-up to be sure it’s in good working order.
How to use the engine block heater
Ensure the receptacle terminals are clean and dry prior to use. To clean
them, use a dry cloth.
Depending on the type of factory installed equipment, your engine block
heater system may consume anywhere between 400 watts or 1000 watts
of power per hour. Your factory installed block heater system does not
have a thermostat; however, maximum temperature is attained after
approximately three hours of operation. Block heater operation longer
than three hours will not improve system performance and will
unnecessarily use additional electricity.
Make sure system is unplugged and properly stowed before driving the
vehicle. While not in use, make sure the protective cover seals the
prongs of the engine block heater cord plug.
BRAKES
Occasional brake noise is normal. If a metal-to-metal, continuous grinding
or continuous squeal sound is present, the brake linings may be worn-out
and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toWarning lights and
chimesin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an anti-lock braking system (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. Noise from the ABS pump motor and
brake pedal pulsation may be observed during ABS braking and the
brake pedal may suddenly travel a little farther as soon as ABS braking is
done and normal brake operation resumes. These are normal
characteristics of the ABS and should be no reason for concern.
