Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

20. Cargo LightThe cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
21. Brake Warning Light This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS). In this case, the light will remain on until
the condition has been corrected. If the problem is related to the brake booster, the ABS pump will run when
applying the brake and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.

262 STARTING AND OPERATING

CAUTION! (Continued)
•Driving through standing water may cause dam-
age to your vehicle’s drivetrain components. Al-
ways inspect your vehicle’s fluids (i.e., engine oil,
transmission/transaxle, axle, etc.) for signs of con-
tamination (i.e., fluid that is milky or foamy in
appearance) after driving through standing water.
Do not continue to operate the vehicle if any fluid
appears contaminated, as this may result in further
damage. Such damage is not covered by the New
Vehicle Limited Warranty.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
•Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stop-
ping distances. Therefore, after driving through
standing water, drive slowly and lightly press on
the brake pedal several times to dry the brakes.
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
•Failure to follow these warnings may result in
injuries that are serious or fatal to you, your
passengers, and others around you.
290 STARTING AND OPERATING

Power Steering Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer.
CAUTION!
Do not use chemical flushes in your power steering
system as the chemicals can damage your power
steering components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!
Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to ensure accurate fluid level reading. Do
not overfill. Use only manufacturer’s recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in “Maintaining Your Vehicle” for further
information.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied, the engine is off and the key fob is
removed from the ignition switch. Also, be certain to
leave an automatic transmission in PARK, or manual
transmission in REVERSE or first gear.
292 STARTING AND OPERATING

BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off), the
brakes will still function. However, you will experience a
substantial increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses normal
braking capability, the remaining system will still func-
tion with some loss of overall braking effectiveness. This
will be evident by increased pedal travel during applica-
tion, greater pedal force required to slow or stop, and
activation of the “Brake Warning Light” and the “ABS
Warning Light” (if equipped) during brake use.
Dual Rear Wheel Models Only
The brake system power assist is provided by a hydro-
boost unit which shares fluid with the power steering
system. You may experience some clicking or hissing
noises from the hydro-boost system during hard braking
conditions.NOTE:
Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid reaches
operating temperature.
Four-Wheel Anti-Lock Brake System
WARNING!
The Four-Wheel Anti-Lock Brake System contains
sophisticated electronic equipment. It may be sus-
ceptible to interference caused by improperly in-
stalled or high output radio transmitting equipment.
This interference can cause possible loss of anti-lock
braking capability. Installation of such equipment
should be performed by qualified professionals.
The Four-Wheel Anti-Lock Brake System (ABS) is de-
signed to aid the driver in maintaining vehicle control
under adverse braking conditions. The system operates

STARTING AND OPERATING 295

4. Press the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Shift the transfer case lever into desired position.
7. Shift the transmission into PARK.
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
CAUTION!
•Do not use a bumper-mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
•Do not disconnect the rear driveshaft because
fluid will leak from the transfer case and damage
the internal parts.
