WHAT IS THE PERSONAL SAFETY
SYSTEM
An advanced safety system that protects
occupants in frontal crashes.
HOW DOES THE PERSONAL
SAFETY SYSTEM WORK
This system provides an improved level of
frontal crash protection to front seat
occupants and is designed to reduce the risk
of airbag-related injuries. The system
analyzes occupant conditions and crash
severity before activating the appropriate
safety devices. During a crash, the restraints
control module may deploy the seatbelt
pretensioners, and one or both stages of the
dual-stage airbags based on crash severity
and occupant conditions.

ENGINE BLOCK HEATER (If Equipped)
Engine Block Heater Precautions
WARNING: Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING:
Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power cable
and may cause an electrical short resulting
in fire, injury and property damage. We recommend that you do the following for
a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by Underwriter’ s
Laboratory (UL) or Canadian Standards
Association (CSA). This extension cord
must be suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and engine block
heater cord plug connections are free
and clear of water. This could cause an
electric shock or fire.
• If the engine block heater cord is under
the hood, do not remove the wiring from
its original location. Do not close the
hood on the extension wiring. •
Park your vehicle in a clean area, clear
of combustible materials.
• Firmly connect the engine block heater
cord and the extension cord.
• Check the extension cord for heat
anywhere when the system has been
operating for approximately 30 minutes.
• Unplug and properly stow the system
before starting and driving your vehicle.
The protective cover seals the terminals
of the engine block heater cord plug
when not in use.
• Check the engine block heater system
for proper operation before winter.
How Does the Engine Block Heater
Work
The engine block heater warms the engine
coolant. This allows the climate control
system to quickly respond. The equipment
includes a heater element installed in the
engine block and a wire harness. You can
connect the system to a grounded 220-240
volt AC electrical source.

CONNECTING A TRAILER
PRECAUTIONS
WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper is
higher than 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.
Do not tow a trailer until you drive your
vehicle at least
1,000 mi (1,600 km).
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You must
distribute the load in your trailer so that
10-15% of the total weight of the trailer is on
the trailer coupler.
Consult your local motor vehicle laws for
towing a trailer.
See the instructions included with towing
accessories for the proper installation and
adjustment specifications. Service your vehicle more frequently if you
tow a trailer.
See Normal Scheduled
Maintenance (page 463).
If you use a rental trailer, follow the
instructions the rental agency gives you.
When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Account for the trailer coupler weight as part
of your vehicle load when calculating the
total vehicle weight.
Do not exceed the load limits.
See
Calculating the Load Limit (page 291). CONNECTING A TRAILER
Trailer Towing Connector
(If Equipped) When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Note:
Install the waterproof protection cap
back onto the trailer towing connector
whenever it is not in use. This helps to
prevent water damage and trailer towing
connector malfunction.

Note:
You cannot use a seven-pin trailer
wiring connector for your vehicle and the
trailer lighting equipment.
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.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Safety Chains
Note: Do not attach safety chains to the
bumper. Always connect the safety chains
to the frame or hook retainers of your trailer
hitch. Install trailer safety chains to the trailer hitch
as recommended by the manufacturer. Cross
the chains under the trailer coupler and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
If the trailer safety chain hook has a latch,
make sure the latch is fully closed.

•
Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly after
you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed control
may turn off when you are towing on
long, steep slopes.
• Shift to a lower gear when driving down
a long or steep hill. Do not continuously
apply the brakes, as they may overheat
and become less effective.
• If your transmission has Grade Assist or
Tow/Haul, use this feature when towing.
This provides engine braking and helps
eliminate excessive transmission shifting
for optimum fuel economy and
transmission cooling. •
If your vehicle has AdvanceTrac with roll
stability control, this system may turn on
during typical cornering maneuvers with
a heavily loaded trailer. This is normal.
Turning the corner at a slower speed
when towing may reduce this tendency.
• If you are frequently towing a trailer in
hot weather, hilly conditions, at the gross
combined weight rating or any
combination of these factors, consider
refilling your rear axle with synthetic gear
lubricant if the axle is not already filled
with it.
• Allow more distance for stopping with a
trailer attached. Anticipate stops and
gradually brake.
• Avoid parking on a slope. However, if
you must park on a slope, turn the
steering wheel to point your vehicle tires
away from traffic flow, set the parking
brake, place the transmission in park (P)
and place wheel chocks in front and back
of the trailer wheels.
Note: Chocks are not included with your
vehicle. LAUNCHING OR RETRIEVING A
BOAT OR PERSONAL
WATERCRAFT
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 in (15 cm)
above the bottom edge of
the rear bumper.
Exceeding
6 in (15 cm) could allow water to
enter vehicle components, causing internal
damage to the components and affecting
driveability, emissions and reliability.
Note: Replace the rear axle lubricant
anytime the rear axle has been submerged
in water.
Note: Disconnect the trailer wiring connector
before backing the trailer into the water.
Note: Reconnect the trailer wiring connector
after removing the trailer from the water.
