Service engine soon
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). The 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.
TheService Engine Soonindicator 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 Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourService Engine Soonlight 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.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the gas cap. After three driving cycles
without these or any other temporary malfunctions present, theService
Engine Soonlight should turn off. (A driving cycle consists of a cold
engine startup followed by mixed city/highway driving.) No additional
vehicle service is required.
If theService Engine Soonlight remains on, have your vehicle serviced
at the first available opportunity.

(Overdrive)
The normal driving position for the
best fuel economy. Transmission
operates in gears one through four.
(Overdrive) can be deactivated
by pressing the transmission control
switch (TCS) on the end of the
gearshift lever.
The transmission control indicator
light (TCIL) (the word OFF) on the
end of the gearshift lever will
illuminate.
Drive± Not shown on the display. Activate by pressing the transmission
control switch (TCS) on the end of the gearshift lever with the gearshift
in the
position. The TCIL (the word OFF) will illuminate on the
gearshift lever. Transmission operates in gears one through three.
(Drive) provides more engine braking than(Overdrive) and is useful
when:
²driving with a heavy load.
²towing a trailer up or down steep hills.
²additional engine downhill braking is desired. If towing a trailer, refer
toDriving while you towin theTrailer towingsection.
To return to
(Overdrive) mode, press the transmission control switch
(TCS). The TCIL (the word OFF) will no longer be illuminated.
Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if driving in
overdrive is not desired.
2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.

Using the N (Neutral) position
The transfer case neutral position overrides the transmission and
puts the vehicle in neutral regardless of transmission gearshift
lever position. The vehicle can move forward or backwards.
This position should only be used
when towing the vehicle.
Do not leave the vehicle unattended with the transfer case in the
N (Neutral) position. Always set the parking brake fully and turn
off the ignition when leaving the vehicle.
Using the electronic shift 4WD system (if equipped)
Positions of the electronic shift system
2H (2WD High)± Power to rear axle only.
4H (4WD High)± Power delivered to front and rear axles for increased
traction.
4L (4WD Low)± Power to front and rear axles at low speeds.
Shifting from 2H (2WD high) to 4H (4WD high)
Move the 4WD control to the 4H at
a stop or up to 88 km/h (55 mph).
²At temperatures below 0ÉC
(32ÉF), shifts from 2H to 4H
should not be performed above
72 km/h (45 mph).
Do not shift into 4H with the
rear wheels slipping.

VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
²Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include passengers or
aftermarket equipment.
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
Certification 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 Certification 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.

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.
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.
Exceeding the maximum GCWR could result in extensive damage
to your vehicle and personal injury.

Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight could result in engine damage, transmission/axle damage,
structural damage, loss of control, and personal injury.
