•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.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
•affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational (RV) towing.
An example of recreational towing would be towing your vehicle behind
a motorhome. These guidelines are designed to ensure that your
transmission is not damaged.

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
When the engine starts, the idle RPM runs faster 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 for the air induction inlet.
Before starting the vehicle:
1. Make sure all occupants buckle their safety belts. For more
information on safety belts and their proper usage, refer to theSeating
and Safety Restraintschapter.
2. Make sure the headlamps and electrical accessories are off.
•Make sure the parking brake is
set.

•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 toBrake system warning
lightin theInstrument Cluster
chapter for information on the brake
system warning light.

WARNING:If a failure has been detected within the
AdvanceTrac
with RSC
system, thesliding caricon
will
illuminate steadily. Verify that the AdvanceTrac
with RSC
system is
not manually disabled (push the AdvanceTrac
with RSC
“Off “
button located on the center of the instrument panel). If thesliding
caricon
still illuminates steadily, have the system serviced by an
authorized dealer immediately. Operating your vehicle with
AdvanceTrac
with RSC
disabled could lead to an increased risk of
loss of vehicle control, vehicle rollover, personal injury and death.
The AdvanceTrac
with RSC
system provides the following stability
enhancement features for certain driving situations:
•Traction Control (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
•Roll Stability Control™ (RSC
), which functions to help avoid a
vehicle roll-over.
The AdvanceTrac
with RSC
system automatically enables each time
the engine is started. All features of the AdvanceTrac
with RSC
system
(TCS, ESC, and RSC
) are active and monitor the vehicle from start-up.
However, the system will only intervene if the driving situation requires
it.
The AdvanceTrac
with RSC

system includes an AdvanceTrac

with RSC
Offbuttononthe
center of the instrument panel, and
a “sliding car” icon
in the
instrument cluster. The “sliding car”
icon
in the instrument cluster will illuminate temporarily during
start-up as part of a normal system self-check, or during driving if a
driving situation causes the AdvanceTrac
with RSC
system to operate.
If the “sliding car” icon
illuminates steadily, verify that the
AdvanceTrac
with RSC
system is not manually disabled by pressing
the AdvanceTrac
with RSC
Offbutton located on the center stack of
the instrument panel. If the “sliding car” icon
remains steadily
illuminated, or if the message center (if equipped) displays SERVICE
RSC NOW, have the system serviced by an authorized dealer
immediately.

When AdvanceTrac
with RSC
performs a normal system self-check,
some drivers may notice a slight movement of the brake, and/or a
rumble, grunting, or grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTrac
with RSC
you may
experience the following:
•A slight deceleration of the vehicle
•The “sliding car”
indicator light will flash.
•A vibration in the pedal when your foot is on the brake pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
Traction Control (TCS)
Traction Control is a driver aid feature that helps your vehicle maintain
traction of the wheels, typically when driving on slippery and/or hilly
road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled in two ways, which may work
separately or in tandem: Engine Traction Control and Brake Traction
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. Traction Control is most active at low speeds.
During Traction Control events the “sliding car” icon
in the
instrument cluster will flash.
If the Traction Control system 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, Traction
Control 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, RSC
, and ESC are not
affected by this condition and 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

with RSC
section following.
