WARNING LIGHTS AND CHIMES
Check engine
Your vehicle is equipped with a
computer that monitors the engine's
emission control system. This
system is commonly known as the
On Board Diagnostics System (OBD
II). This OBD II system protects the environment by ensuring that your
vehicle continues to meet government emission standards. The OBD II
system also assists the service technician in properly servicing your
vehicle.
TheCheck Engineindicator light illuminates when the ignition is first
turned to the ON position to check the bulb. If it comes on after the
engine is started, one of the engine's emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the check engine light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourCheck Enginelight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.

AIR SUSPENSION SYSTEM (IF EQUIPPED)
The load leveling feature of the air suspension automatically keeps the
vehicle at a constant level if a load is added or removed from the vehicle.
This system maintains the vehicle height at a constant level by
automatically adding air or releasing air from the springs to offset
changes in vehicle loads.
When ever a door is opened (including the liftgate) the system
memorizes and maintains the height of the vehicle until all doors are
closed.
It is normal to hear a buzz or clicking from the air compressor on the
vehicle when the ignition is turned off. The system stays energized for 40
minutes after the ignition is turned off to compensate for any load
changes made after the vehicle is parked.
The air suspension shut-off switch is
located in the cargo area behind the
left rear quarter trim panel.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior to
jacking, hoisting or towing your
vehicle.
Normal vehicle operation does not
require any action by the driver.
PREPARING TO DRIVE YOUR VEHICLE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.

²Payload:Combined maximum allowable weight of cargo, passengers
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
²GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
²GVWR (Gross Vehicle Weight Rating):Maximum total weight of
the base vehicle, passengers, optional equipment and cargo. The
GVWR is specific to each vehicle and is listed on the Safety
Compliance Label on the driver's door pillar.
²GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Safety Compliance Label on the driver's door pillar.
²GCW (Gross Combined Weight):The combined weight of the
towing vehicle (including passengers and cargo) and the trailer.
²GCWR (Gross Combined Weight Rating):Maximum combined
weight of towing vehicle (including passengers and cargo) and the
trailer. The GCWR indicates the maximum loaded weight that the
vehicle is designed to tow.
²Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
²Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle (including passengers and cargo) is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
²Trailer Weight Range:Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
Driving

Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum gross combined weight rating (GCWR)
chart to find the maximum GCWR for your type engine and rear axle
ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum trailer weight your vehicle can tow
and must fall below the maximum shown under maximum trailer weight
on the chart.
DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage.
TRAILER TOWING
Trailer towing with your vehicle may require the use of a trailer tow
option package.
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:
²Stay within your vehicle's load limits.
Driving
165

²Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
²Use extra caution when driving while trailer towing. Refer toDriving
while you towin this chapter.
²Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the Scheduled Maintenance Guide.
²Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
²Refer 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 vehicle when figuring the total weight.

Notes:For high altitude operation, reduce GCW by 2% per 300 meters
(1 000 ft) elevation. For definition of terms and instructions on calculating
your vehicle's load, refer toVehicle loadingin this chapter. Maximum
trailer weights shown. The combined weight of the completed towing
vehicle and the loaded trailer must not exceed the GCWR.
Towing a trailer over 1 588 kg (3 500 lbs.) requires a weight distributing
hitch.
Do not exceed the GVWR or the GAWR specified on the
certification label.
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 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. You must distribute the load in your trailer so that 10% of
the total weight of the trailer is on the tongue.
Use a frame-mounted weight distributing hitch for trailers over
1 588 kg (3 500 lb).
