capacity to carry you, 4 of your friends and all the golf bags? You and
four friends average 220 lb. (99 kg) each and the golf bags weigh
approximately 30 lb. (13.5 kg) each. The calculation would be: 1400 –
(5 x 220) – (5 x 30) = 1400 – 1100 – 150 = 150 lb. Yes, you have
enough load capacity in your vehicle to transport four friends and
your golf bags. In metric units, the calculation would be: 635 kg —
(5 x 99 kg) — (5 x 13.5 kg) = 635 — 495 — 67.5 = 72.5 kg.
•A final example for your vehicle with 1400 lb. (635 kg) of cargo and
luggage capacity. You and one of your friends decide to pick up
cement from the local home improvement store to finish that patio
you have been planning for the past 2 years. Measuring the inside of
the vehicle with the rear seat folded down, you have room for 12-100 lb.
(45 kg) bags of cement. Do you have enough load capacity to
transport the cement to your home? If you and your friend each weigh
220 lb. (99 kg), the calculation would be: 1400 – (2 x 220) – (12 x 100) =
1400 – 440 – 1200 = – 240 lb. No, you do not have enough cargo
capacity to carry that much weight. In metric units, the 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:
1400 – (2 x 220) – (9 x 100) = 1400 – 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
Your vehicle is capable either of towing Class I trailers or up to Class II
trailers when equipped with the optional trailer tow package.
If your vehicle does not have the optional trailer tow package your
vehicle is partially prepped for trailer tow lamp wiring but you will also
need to install electrical kit (15A416). This kit contains fuses and relays
to isolate the vehicle lighting circuitry from the trailer lighting and an
adapter wiring harness containing the standard 4-pin trailer plug. Refer
to theTrailer lampssection in this chapter for additional information.
Do not tow above 2,000 lb. (907 kg) without the
manufacturer-installed trailer tow package.

A new underbody wiring harness (14406) will be a component to this kit
and will need to be installed, if applicable, per instructions located in the
service kit.
If your vehicle has the optional trailer tow package it comes with heavy
duty cooling fans, auxiliary transmission fluid cooler, an auxiliary engine
oil cooler, heavy duty battery, trailer tow wiring (including fuses and
relays to isolate the vehicle lighting circuitry from the trailer lighting)
and a kit (in a cardboard box) that includes an adapter wiring harness
that contains the standard 4-pin trailer plug.
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 procedure:
•Stay within your vehicle’s load limits. If exceeded, cargo should be
removed from the trailer and/or the vehicle until all weights are within
specified limits.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•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 the scheduled maintenance
information.
•Do not tow a trailer until your vehicle has been driven at least
500 miles (800 km).
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.

Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter. Remember to figure in the tongue
load of your loaded trailer when figuring the total weight.
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 control
and personal injury.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized dealer or a
reliable trailer dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch that does not exceed your vehicle’s capability. See the
Tongue Loadsection in the trailer towing chart earlier in this section for
range details on a specific trailer load.
Safety chains
Always connect the trailer’s safety chains to the hook retainers on the
hitch. To connect the trailer’s safety chains, cross the chains under the
trailer tongue and allow slack for turning corners.

207
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
Be sure your trailer conforms to all applicable local and Federal
Regulations regarding trailer braking. If your trailer is equipped with
electronically controlled brakes you will need to have an electronic brake
controller with associated wiring installed to your vehicle by an
authorized dealer.
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.
Do not splice into the vehicle lamp wiring for trailer lamps. Your
vehicle uses an advanced electronic module to control and
monitor your vehicle lamps. Splicing into the wiring or attaching
wiring to the vehicle bulb. may DISABLE the rear vehicle lamps
or cause them not to function properly. Your lamp outage feature
may also be disabled or provide incorrect information.
See your authorized dealer or trailer rental agency for proper
instructions and equipment for hooking up trailer lamps.
Driving while you tow
When towing a trailer:
•Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, 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.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to

Understanding the gearshift positions of the 4–speed automatic
transmissionin theDriving chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourScheduled Maintenance
Informationfor more information.
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.
•Allow more distance for stopping with a trailer attached.
•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.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCW, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 500 miles (800 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (112 km/h) with no full throttle starts.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
•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 with all four wheels on the ground (such as behind a
recreational vehicle).
These guidelines are designed to ensure that your transmission is not
damaged due to insufficient lubrication.
All Front Wheel Drive (FWD) vehicles:
It is not recommended to tow front wheel drive vehicles with the front
drive wheels on the ground. It is recommended to tow your vehicle with
the drive wheels on a dolly or two wheel car hauling trailer.
In case of a roadside emergency with a disabled vehicle (without access
to wheel dollies, car hauling trailer or flatbed transport vehicle) your
vehicle can be flat towed (all wheels on the ground) under the following
conditions:
•Place the transmission in N (Neutral).
•Maximum speed is 35 mph (56 km/h).
•Maximum distance is 50 miles (80 km).

•A slight deceleration of the vehicle
•The TRAC ACTIVE indicator light will illuminate
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
•If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during AdvanceTracoperation.
If the AdvaceTrac system is activated for an extended period of time, the
brake portion of the system will shut down to allow the brakes to cool
down. A limited AdvanceTracfunction using only engine power
reduction will still help control the wheels from over-spinning. When the
brakes have cooled down, the system will again function normally.
Anti-lock braking is not affected by this condition and will function
normally during the cool-down period.
Do not alter or modify your vehicle’s suspension or steering; the
resulting changes to the vehicle’s handling can adversely affect
the AdvanceTracsystem. Also, do not install a stereo
loudspeaker near the front center console or under either front
seat. The speaker vibrations can adversely affect the
AdvanceTracsensors located in this area.
Aggressive driving in any road conditions can cause you to lose
control of your vehicle increasing the risk of severe personal
injury or property damage. The occurrence of an AdvanceTracevent
is an indication that at least some of the tires have exceeded their
ability to grip the road; this may lead to an increased risk of loss of
vehicle control, vehicle rollover, personal injury and death. If you
experience a severe road event, SLOW DOWN.
STEERING
To prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump reservoir
fluid level (below the MIN mark on the reservoir).
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.

When parking, do not use the gearshift in place of the parking
brake. Always set the parking brake fully and make sure that the
gearshift is securely latched in Park (P). Turn off the ignition
whenever you leave your vehicle. Never leave your vehicle unattended
while it is running. If you do not take these precautions, your vehicle
may move unexpectedly and injure someone.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
If necessary, try turning the Traction Controlor AdvanceTracsystem
off. This will allow the wheels to spin, which may help to free your stuck
vehicle. For more information, refer toTraction Control(if equipped)
orAdvanceTracstability enhancement system (if equipped)in this
chapter.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
