FOUR-WHEEL DRIVE
OPERATION
Quadra-Trac I®Operating
Instructions/Precautions
• The Quadra-Trac I®is a single-speed
(HI range only) transfer case, which
provides convenient full-time
four–wheel drive. No driver interaction
is required. The Brake Traction Control
(BTC) System, which combines
standard ABS and Traction Control,
provides resistance to any wheel that is
slipping to allow additional torque
transfer to wheels with traction.
Quadra-Trac II®/Quadra-Drive
II®Operating Instructions/
Precautions
• The Quadra-Trac II®/Quadra-Drive II®
transfer case is fully automatic in the
normal driving 4WD HI mode. The
Quadra-Trac II
®/Quadra-Drive II®
transfer case provides three mode
positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
• This transfer case is fully automatic in the 4WD HI mode. • When additional traction is required,
the 4WD LOW position can be used to
lock the front and rear driveshafts
together and force the front and rear
wheels to rotate at the same speed.
The 4WD LOW position is intended for
loose, slippery road surfaces only.
Driving in the 4WD LOW position on dry,
hard-surfaced roads may cause
increased tire wear and damage to
driveline components.
• When operating your vehicle in 4WD LOW, the engine speed is
approximately three times that of the
4WD HI position at a given road speed.
Take care not to overspeed the engine
and do not exceed 25 mph (40 km/h).
NOTE:
• If shift conditions/interlocks are not met, or a transfer case motor
temperature protection condition
exists, a “CHECK SHIFT PROCEDURES”
message will flash from the Electronic
Vehicle Information Center (EVIC).
WARNING!
You or others could be injured if you
leave the vehicle unattended with the
transfer case in the N (Neutral)
position without first fully engaging
the parking brake. The transfer case
N (Neutral) position disengages both
the front and rear driveshafts from
the powertrain and will allow the
vehicle to move regardless of the
transmission position. The parking
brake should always be applied when
the driver is not in the vehicle.

OFF-ROAD CAPABILITIES

WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have an accident.
Have the vehicle checked immediately.
- Malfunction Indicator Light (MIL)
• Certain conditions, such as a loose or missing gas cap, poor fuel quality, etc., mayilluminate the MIL after engine start. The vehicle should be serviced if the light stays on
through several typical driving cycles. In most situations, the vehicle will drive normally
and not require towing.
• If the MIL flashes when the engine is running, serious conditions may exist that could lead to immediate loss of power or severe catalytic converter damage. We recommend
you do not operate the vehicle. Have the vehicle serviced as soon as possible if this
occurs.
- Electronic Stability Program (ESP) Indicator Light/Brake Assist
System (BAS) Warning Light
• If the ESP/BAS warning light comes on continuously with the engine running, a malfunction has been detected.
• If this light remains on after several ignition cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), we recommend you
drive to the nearest Service Center as soon as possible to have the problem diagnosed
and corrected.
- Charging System Light
• This light shows the status of the electrical charging system. If the charging system lightremains on, it means that the vehicle is experiencing a problem with the charging
system.
• We recommend you do not continue driving if the charging system light is on. Have the vehicle serviced immediately.
- Oil Pressure Warning Light
• This light indicates low engine oil pressure. If the light turns on while driving, stop thevehicle and shut off the engine as soon as possible. A chime will sound for four minutes
when this light turns on.
• We recommend you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
- Anti-Lock Brake (ABS) Light
• This light monitors the Anti-Lock Brake System (ABS).
• If the light is not on during starting, stays on, or turns on while driving, we recommendyou drive to the nearest Service Center and have the system serviced as soon as
possible.
WHAT TO DO IN EMERGENCIES
46

- Electronic Throttle Control (ETC) Light
• This light informs you of a problem with the Electronic Throttle Control (ETC) system.
• If a problem is detected, the light will come on while the engine is running. Cycle theignition key when the vehicle has completely stopped and the shift lever is placed in the
PARK position; the light should turn off.
• If the light remains lit with the engine running, your vehicle will usually be drivable; however, see an authorized dealer for service as soon as possible. If the light is flashing
when the engine is running, immediate service is required and you may experience
reduced performance, an elevated/rough idle or engine stall and your vehicle may
require towing.
- Airbag Warning Light
• If the light is not on during starting, stays on, or turns on while driving, we recommendyou drive to the nearest Service Center and have the system serviced as soon as
possible.
Fuel Cap/Loose Gas Cap Message
• If a “gas cap” message (shown as Check Gascap) appears, tighten the gas cap until a“clicking” sound is heard.
• If the message continues to appear for more than three days after tightening the gas cap, see your authorized dealer.
Oil Change Indicator
Message
• If an “oil change” message (shown as Oil Change Required) appears and a single chimesounds, it is time for your next required oil change.
Resetting The Light After Servicing
• Turn the ignition switch to the ON/RUN position (do not start engine).
• Fully depress the accelerator pedal three times within 10 seconds.
• Turn the ignition switch to the OFF/LOCK position.
IF YOUR ENGINE OVERHEATS
• In any of the following situations, you can reduce the potential for overheating by takingthe appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C system adds heat to the engine cooling system and turning the A/C off can help remove this heat.
• You can also turn the Temperature Control to maximum heat, the Mode Control to floor and the Fan Control to high. This allows the heater core to act as a supplement to the
radiator and aids in removing heat from the engine cooling system.
