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.

4WD CONTROL (IF EQUIPPED)
This control operates the 4WD.
Refer to theDrivingchapter for
more information.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the reverse gear is selected.
The RSS will assist the driver in detecting certain objects while the
vehicle slowly moves in reverse at speeds less than 8 km/h (3 mph). The
RSS is not effective at speeds greater than 8 km/h (3 mph) and may not
detect certain angular or moving objects. The weather may also affect
the function of RSS. RSS may have reduced performance in the rain or
snow.

Forced Downshifts
To gain acceleration in(Overdrive) or Drive (O/D OFF) when passing
another vehicle, push the accelerator to the floor. The transmission will
downshift to the appropriate gear: fourth, third, second or first gear.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
When Four±wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD power can be selected when
additional driving power is desired.
If equipped with the Electronic Shift 4WD System, and the
instrument panel control is moved to 4WD Low while the vehicle
is moving, the system will not engage and no damage will occur to
the 4WD system.
All utility-type vehicles and 4WD vehicles have special design and
equipment features to make them capable of performing in a wide
variety of off-road applications. Specific design characteristics give them
higher centers of gravity than ordinary passenger cars.
Utility and four-wheel drive vehicles arenotdesigned for
cornering at speeds as high as passenger cars any more than
low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or abrupt maneuvers in these
vehicles.
4WD operation is not recommended on dry pavement. Doing so could
result in difficult disengagement of the transfer case, increased tire wear
and decreased fuel economy.
CONTROL-TRAC AUTOMATIC FOUR-WHEEL DRIVE SYSTEM
(IF EQUIPPED)
The 4WD system uses all four wheels to power the vehicle. This
increases traction, enabling you to drive your 4x4 over terrain and road
conditions not normally traveled by two-wheel drive vehicles.
Power is supplied to all four wheels through a transfer case that allows
you to select a four-wheel drive mode best suited for your current
driving conditions.
