Transmission fluid temperature gauge:If the gauge is in the:
Normal area(normal) - the
transmission fluid is within the
normal operating temperature
(between “H” and “C”).
Yellow area(warning) — the
transmission fluid is higher than
normal operating temperature. This
can be caused by special operation
conditions (i.e. snowplowing, towing
or off road use). Refer toSpecial
Operating Conditionsin the
scheduled maintenance
informationfor instructions. Operating the transmission for extended
periods of time with the gauge in the yellow area may cause internal
transmission damage.
Altering the severity of the driving conditions is recommended to lower
the transmission temperature into the normal range.
Red area(over temperature) —
the transmission fluid is overheating.
Stop the vehicle to allow the
temperature to return to normal
range.
If the gauge is operating in the Yellow or Red area, stop the vehicle and
verify the airflow is not restricted such as snow or debris blocking airflow
through the grill. If the gauge continues to show high temperatures, see
your authorized dealer.

the transmission will automatically return to normal mode with Tow/Haul
feature deactivated, refer to theDrivingchapter for more information.
SPEED CONTROL (IF EQUIPPED)
With speed control set, you can maintain a set speed without keeping
your foot on the accelerator pedal.
WARNING:Do not use the speed control in heavy traffic or on
roads that are winding, slippery or unpaved.
Setting speed control
The controls for using your speed
control are located on the steering
wheel for your convenience.

GVWR (Gross Vehicle Weight
Rating)– is the maximum
allowable weight of the fully loaded
vehicle (including all options,
equipment, passengers and cargo).
The GVWR is shown on the
Safety Compliance Certification
Label located on the B-Pillar or
the edge of the driver’s door.
The GVW must never exceed the
GVWR.
WARNING:Exceeding the Safety Compliance Certification Label
vehicle weight rating limits could result in substandard vehicle
handling or performance, engine, transmission and/or structural
damage, serious damage to the vehicle, loss of control and personal
injury.
GCW (Gross Combined Weight)– is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating)– is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicles’ braking system is rated for operation at
GVWR, not at GCWR. Separate functional brakes should be used for safe
control of towed vehicles and for trailers where the GCW of the towing
vehicle plus the trailer exceed the GVWR of the towing vehicle.The
GCW must never exceed the GCWR.

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 towing vehicle braking system is rated for operation at the
GVWR, not the GCWR.
Separate functioning brake systems are required for safe control
of towed vehicles and trailers weighing more than 1500 lb.
(680 kg) when loaded.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. 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 (113 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.
•Anticipate stops and brake gradually.
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 GCWR, 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 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 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.

STARTING
Positions of the ignition
1. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
2. LOCK, locks the automatic
transmission gearshift lever and
allows key removal.
3. OFF, shuts off the engine and all
accessories without locking the
steering wheel.
4. ON, all electrical circuits operational. Warning lights illuminated. Key
position when driving.
5. 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, avoid pressing 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 toStarting 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.
