The driver and front passenger Belt-Minderfeatures can be
deactivated/activated by performing the following procedure:
Before following the procedure, make sure that:
• The parking brake is set
• the gearshift is in P (Park) (automatic transmission) or the neutral
position (manual transmission)
• The ignition switch is in the off position
• The driver and front passenger seat belts are unbuckled
WARNING: While the design allows you to deactivate your
Belt-Minder, this system is designed to improve your chances of
being safely belted and surviving an accident. We recommend you
leave the Belt-Minder system activated for yourself and others who
may use the vehicle. To reduce the risk of injury, do not
deactivate/activate the Belt-Minder feature while driving the vehicle.
1. Turn the ignition switch to the on position. DO NOT START THE ENGINE.
2. Wait until the seat belt warning light turns off (Approximately one minute).
• Step 3 must be completed within 50 seconds after the seat belt
warning light turns off.
3. For the seating position being disabled, at a moderate speed, buckle then unbuckle the seat belt nine times, ending in the unbuckled
state. Step 3 must be completed within 50 seconds after the seat
belt warning light turns off.
• After Step 3, the seat belt warning light will be turned on for three
seconds.
4. Within approximately seven seconds of the light turning off, buckle then unbuckle the seat belt.
• This will disable the Belt-Minder feature for that seating position if it
is currently enabled. As confirmation, the seat belt warning light will
flash four times per second for three seconds.
• This will enable the Belt-Minder feature for that seating position if it
is currently disabled. As confirmation, the seat belt warning light will
flash four times per second for three seconds, followed by three
seconds with the light off, then followed by the seat belt warning light
flashing four times per second for three seconds again.

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 vehicle’s 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.

Special loading instructions for owners of pickup trucks and
utility-type vehicles
WARNING:For important information regarding safe operation
of this type of vehicle, see the Preparing to drive your
vehicle section in the Drivingchapter of this Owner’s Manual.
WARNING:Loaded vehicles may handle differently than
unloaded vehicles. Extra precautions, such as slower speeds and
increased stopping distance, should be taken when driving a heavily
loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.

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
For towing trailers up to 2,000 lb. (907 kg), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue loads through the
