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.
Your vehicle is capable of towing a trailer up to 1,000 lb (454 kg) gross
trailer weight with a maximum tongue load of 100 lb (45 kg).
Follow these guidelines to ensure safe towing:
•Do not tow a trailer until your vehicle has been driven at least
500 miles (800 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 chapter.
•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 and instructions on
calculating your vehicle’s load, 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.

WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
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.
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.
WARNING:Do not operate Adaptive Cruise Control (ACC)
when towing a trailer equipped with brakes. Aftermarket trailer
brakes will not function properly when ACC is activated, which may
lead to loss of vehicle control, increasing the risk of serious injury.

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. 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 the “M” position,
then use the paddle shifters to manually shift to a lower gear. Do not
apply the brakes continuously, as they may overheat and become less
effective. For more information on transmission operation and gear
positions, seeAutomatic transmission operationin theDriving
chapter.
•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 below.
All-wheel drive (AWD) 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 AWD 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 AWD 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 below.

ADVANCETRACSTABILITY ENHANCEMENT SYSTEM
Your vehicle is equipped with the AdvanceTracsystem. The
AdvanceTracsystem provides the following stability enhancement
features for certain driving situations:
•Traction control system (TCS), which functions to help avoid
drive-wheel spin and loss of traction.
•Electronic stability control (ESC), which functions to help avoid skids
or lateral slides
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracsystem. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac
system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTracsensors.
Reducing the effectiveness of the AdvanceTracsystem could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this
could reduce the operator’s ability to control the vehicle potentially
resulting in a loss of vehicle control, vehicle rollover, personal injury
and death. If your AdvanceTracsystem activates, SLOW DOWN.
WARNING:If a failure has been detected within the
AdvanceTracsystem, the stability control light will illuminate
steadily, and you may hear a chime. If equipped with a message center,
the vehicle will also indicate a failure with the brake system. Have the
system serviced by an authorized dealer immediately.

control. Engine traction control works to limit drive-wheel spin by
momentarily reducing engine power. Brake traction control works to limit
wheel spin by momentarily applying the brakes to the wheel that is
slipping. The TCS is most active at low speeds.
During TCS events, the stability control light in the instrument cluster
will flash.
If the TCS is activated excessively in a short period of time, the braking
portion of the system may become temporarily disabled to allow the
brakes to cool down. In this situation, the TCS will use only engine
power reduction or transfer to help control the wheels from
over-spinning. When the brakes have cooled down, the system will regain
all features. Anti-lock braking and ESC will continue to function during
the cool-down period.
The engine traction control and brake traction control system may be
deactivated in certain situations. See theSwitching off AdvanceTrac
section below.
Electronic stability control (ESC)
Electronic stability control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During ESC events, the stability control light in the instrument cluster
will flash.
Certain adverse driving maneuvers may activate the ESC system, which
include but are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).

Troubleshooting
Why isn’t APA searching for a parking space?
•You may have deactivated the AdvanceTracsystem.
•One of the doors (except the driver’s door) may not be securely
closed.
Why doesn’t APA offer a particular parking space?
•Something may be contacting the front bumper or side sensors. Clear
any material stuck to the sensors.
•There may not be enough room to maneuver the vehicle into the
space. Remember, there needs to be enough space on the opposite
side of the vehicle to allow the front of the vehicle to swing out as you
back into the space.
•The vehicle is not driven close enough to the parking space, less than
60 inches (1.5 m) from neighboring parked vehicles.
•The vehicle is driven too close to the side objects (e.g. less than
16 inches [41 cm] from neighboring parked vehicles).
•You may be driving in R (Reverse). APA can only look for a parking
space while moving forward.
Why doesn’t APA position the vehicle where I want in the space?
•The driver allows the vehicle to roll in the opposite direction of the
transmission (such as rolling forward when R (Reverse) gear is
selected.
•You may be driving in R (Reverse). APA can only look for a parking
space while moving forward.
•There may be an irregular curb along the parking space. APA might
not be able to align the vehicle to curbs that are damaged, very
shallow or covered with material such as debris, leaves, snow, or tarps.
•The vehicles or objects bordering the space may not be positioned
appropriately.
•The vehicle was pulled further up from the parking space than usual
while driving by the space. APA performs best when you drive the
same distance past the entire length of the parking space whenever
parking your vehicle.
•The tires may not be installed and maintained correctly. For example,
one or more tires may not be inflated correctly, may not be of the
same size, or may not be authorized for use on this vehicle.
•The vehicle had a repair or alteration that is not authorized by the
manufacturer.
