calculation would be: 635 kg - (2 x 99 kg) - (12 x 45 kg) = 635 - 198 -
540 = -103 kg. You will need to reduce the load weight by at least
240 lb. (104 kg). If you remove 3-100 lb. (45 kg) cement bags, then
the load calculation would be:
1,400 - (2 x 220) - (9 x 100) = 1,400 - 440 - 900 = 60 lb. Now you
have the load capacity to transport the cement and your friend home.
In metric units, the calculation would be: 635 kg - (2 x 99 kg) - (9 x
45 kg) = 635 - 198 - 405 = 32 kg.
The above calculations also assume that the loads are positioned in your
vehicle in a manner that does not overload the Front or the Rear Gross
Axle Weight Rating specified for your vehicle on the Safety Compliance
Certification Label found on the edge of the driver’s door.
TRAILER TOWING
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing:
•Do not tow a trailer until your vehicle has been driven at least
1,000 miles (1,600 km).
•Consult your local motor vehicle laws for towing a trailer.
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•Stay within your vehicle’s load limits.
•Use extra caution when driving while trailer towing. Refer toDriving
while you towin this section.
•Service your vehicle more frequently if you tow a trailer. Refer to
Special operating conditionsin your scheduled maintenance.
For load specification terms found on the label, refer toVehicle loading
- with and without a trailerin this chapter. Remember to figure in the
tongue load of your loaded vehicle when figuring the total weight.
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.

For towing trailers up to 3500 lb (1588 kg), use a weight-carrying
hitch and ball which uniformly spreads the trailer tongue loads through
the vehicle’s underbody structure. For towing trailers over 3500 lb
(1588 kg), up to 4500 lb (2042 kg), it is recommended to use a
weight-distributing hitch to increase front axle load while towing.
2For towing trailers up to 4500 lb (2042 kg), use a weight-carrying
hitch and ball which uniformly spreads the trailer tongue loads through
the vehicle’s underbody structure.
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; use a
load-carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
Weight-distributing hitch
When hooking-up a trailer using a weight-distributing hitch, always use
the following procedure:
1. Park the vehicle (without the trailer) on a level surface.
2. Measure the height of the top of the front wheel opening on the
fender, this is H1.
Tires, Wheels and Loading

USA(fus)

3. Attach the trailer to the vehicle without the weight distributing bars
connected.
4. Measure the height of the top of the front wheel opening on the
fender a second time, this is H2.
5. Install and adjust the tension in the weight distributing bars so that
the height of the front fender is approximately halfway between H1 and
H2.
6. Check that the trailer is level. If not level, adjust the ball height
accordingly and repeat Steps 3–6.
WARNING:Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was before attaching the trailer. Doing so will defeat the function of
the weight-distributing hitch, which may cause unpredictable handling,
and could result in serious personal injury.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
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 brake controller connector (if equipped)
The trailer brake controller
connector is located under the
instrument panel above the brake
pedal.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Do not
connect trailer lamps directly to your vehicle’s tail lamps. This can cause
damage to your vehicle’s electrical system. Contact your authorized
dealer or trailer rental agency for proper instructions and equipment for
hooking-up trailer lamps.
WARNING:Never connect any trailer lamp wiring to the
vehicle’s tail lamp wiring; this 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:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•It is recommended to select the “M” gear position when additional
engine braking is needed. In situations such as prolonged downhill
driving on steep grades (i.e., driving in mountainous areas), additional
engine braking is needed to reduce the load on the vehicle’s regular
brake system to prevent them from overheating. For more information
on transmission operation and gear positions, seeAutomatic
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.

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 sun visor and
the roof, or in the overhead console area), or in the third row seat cup
holder and armrest 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 in the rear of the center console utility
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 in the center console utility compartment. 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, 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.

•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 will use .4 to 1.0 kilowatt-hours of energy per hour of use. 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

and bring your vehicle to a safe stop. Turn the engine off, shift to P
(Park) and apply the parking brake, and then inspect the accelerator
pedal for any interferences. If none are found and the condition persists,
have your vehicle towed to the nearest authorized dealer.
Parking brake
Apply the parking brake whenever
the vehicle is parked. To set the
parking brake, press the parking
brake pedal down until the pedal
stops.
The BRAKE warning lamp in the
instrument cluster illuminates and
remains illuminated (when the
ignition is turned on) until the
parking brake is released.
WARNING:Always set the parking brake fully and make sure
that the gearshift is securely latched in P (Park).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Press the parking brake pedal
downward again to release the
parking brake. Driving with the
parking brake on will cause the
brakes to wear out quickly and
reduce fuel economy.
Note:If the vehicle is driven with
the parking brake applied, a chime
will sound.

Roll Stability Control™ (RSC)
Roll Stability Control™ (RSC) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSCoperates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
During an event that activates the RSCsystem, the stability control
light in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the RSCsystem, which
include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
Switching off traction control
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off the traction control feature of the AdvanceTrac
with RSCsystem may be beneficial because the wheels are allowed to
spin. This will restore full engine power and will enhance momentum
through the obstacle.
To turn off traction control, press
the AdvanceTracbutton. The
button could look like either of the
two graphics shown. Full features of
the TCS can be restored by pressing
the traction control button again or
by turning off and restarting the
engine.
If you switch off the traction
control, the stability control off light
will illuminate steadily. Pressing the
traction control button again will
turn off the stability control light.
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function; however, ESC and RSCare
disabled.
