CAUTION!
•Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
•Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing wa-
ter.
•Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.(Continued)
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.
290 STARTING AND OPERATING

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.
ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance and a
narrower track to make them capable of performing in a
wide variety of off-road applications. Specific design
characteristics give them a higher center of gravity than
ordinary cars.
An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems.
They are not designed for cornering at the same speeds as
conventional two-wheel drive vehicles any more than
low-slung sports cars are designed to perform satisfacto-
rily in off-road conditions. If at all possible, avoid sharp
turns or abrupt maneuvers. As with other vehicles of this
type, failure to operate this vehicle correctly may result in
loss of control or vehicle rollover.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability

STARTING AND OPERATING 291

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. Also, be certain to leave an
automatic transaxle in PARK, or manual transaxle in
REVERSE or first gear.
5
STARTING AND OPERATING 293

BRAKE SYSTEM
Your vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (for example, repeated brake applications
with the engine off), the brakes will still function. How-
ever, the effort required to brake the vehicle will be much
greater than that required with the power system oper-
ating.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.If either of the two hydraulic systems lose normal capa-
bility, the remaining system will still function with some
loss of overall braking effectiveness. This will be evident
by increased pedal travel during application and greater
pedal force required to slow or stop. In addition, if the
malfunction is caused by an internal leak, as the brake
fluid in the master cylinder drops, the “Brake Warning
Light” will light.
WARNING!
Driving a vehicle with the “Brake Warning Light” on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have an accident. Have the vehicle checked immedi-
ately.
296 STARTING AND OPERATING

WARNING!
The Anti-Lock Brake System (ABS) contains sophis-
ticated electronic equipment that may be susceptible
to interference caused by improperly installed or
high output radio transmitting equipment. This in-
terference can cause possible loss of Anti-Lock brak-
ing capability. Installation of such equipment should
be performed by qualified professionals.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle may be equipped with an optional ad-
vanced electronic brake control system that includes
Anti-Lock Brake System (ABS), Traction Control System (TCS), Brake Assist System (BAS), Electronic Roll Mitiga-
tion (ERM), Hill Start Assist (HSA), and Electronic Sta-
bility Control (ESC). All systems work together to en-
hance vehicle stability and control in various driving
conditions and are commonly referred to as ESC.
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lockup and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in “Starting and
Operating” for further information.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake pres-
sure is applied to the slipping wheel(s) and engine power
is reduced to provide enhanced acceleration and stability.
A feature of the TCS system functions similar to a limited
5
STARTING AND OPERATING 299

slip differential and controls the wheel spin across a
driven axle. If one wheel on a driven axle is spinning
faster than the other, the system will apply the brake of
the spinning wheel. This will allow more engine torque to
be applied to the wheel that is not spinning. This feature
remains active even if TCS and ESC are in either the
“Partial Off” or “Full Off” modes. Refer to “Electronic
Stability Control (ESC)” in this section of this manual.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not “pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
•The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevail-
ing road conditions.
•The BAS cannot prevent accidents, including
those resulting from excessive speed in turns,
driving on very slippery surfaces, or hydroplan-
ing. Only a safe, attentive, and skillful driver can
prevent accidents.
•The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user ’s safety
or the safety of others.
300 STARTING AND OPERATING

Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicles speed
are sufficient to potentially cause wheel lift, it applies the
brake of the appropriate wheel and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It can not
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.NOTE:
Anytime the ESC system is in the “Full Off”
mode, ERM is disabled. Refer to “Electronic Stability
Control (ESC)” in this section for a complete explanation
of the available ESC modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or roll overs, especially those
that involve leaving the roadway or striking objects
or other vehicles. Only a safe, attentive, and skillful
driver can prevent accidents. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopar-
dize the user’s safety or the safety of others.
5
STARTING AND OPERATING 301

For vehicles not equipped with the EVIC, perform the
following steps:
NOTE:You must complete Steps 1 through 8 within
90 seconds.
1. Center the steering wheel (front wheels pointing
straight forward).
2. Shift the transaxle into NEUTRAL.
3. Apply the parking brake.
4. Start the engine.
5. Release the clutch pedal.
6. Rotate the steering wheel one-half turn to the left.
7. Press the “ESC Off” switch (located in the lower
switch bank below the climate controls) four times within
20 seconds. The “ESC Off Indicator Light” should turn on
and turn off two times. 8. Rotate the steering wheel back to center and then an
additional half-turn to the right.
9. Turn the ignition switch to the OFF position and then
back to the ON position. If the sequence was completed
properly, the “ESC Off Indicator Light” will blink several
times to confirm HSA is disabled.
10. Repeat these steps if you want to return this feature
to it’s previous setting.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering or under-steering of the vehicle by
applying the brake of the appropriate wheel to assist in
counteracting the over-steering or under-steering condi-
tion. Engine power may also be reduced to help the
vehicle maintain the desired path. ESC uses sensors in
the vehicle to determine the vehicle path intended by the
5
STARTING AND OPERATING 303

ESC Malfunction Indicator Light
The “ESC Malfunction Indicator Light” in the
instrument cluster will come on when the
ignition switch is turned to the ON position. It
should go out with the engine running. If the
“ESC Malfunction Indicator Light” comes on continu-
ously with the engine running, a malfunction has been
detected in the ESC system. 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), see your authorized dealer as soon as possible
to have the problem diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the “ESC Malfunc-
tion Indicator Light” come on momentarily each time
the ignition switch is turned ON.
•Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
•The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
ESC Operating Modes
The ESC system has three available operating modes for
four–wheel drive equipped vehicles and two available
operating modes for two–wheel drive equipped vehicles.
Full On (Four-Wheel Drive Models) or On (Two-Wheel
Drive Models)
This is the normal operating mode for ESC. Whenever
the vehicle is started the ESC system will be in this “On”
mode. This mode should be used for most driving
situations. ESC should only be turned to “Partial Off” or
“ESC Off” for specific reasons as noted below.
5
STARTING AND OPERATING 305

Partial Off (Four-Wheel Drive Models) or On
(Two-Wheel Drive Models)
This mode is entered by momentarily pressing the “ESC
Off” switch. When in “Partial Off” mode, the TCS portion
of ESC, except for the “limited slip” feature described in
the TCS section, has been disabled and the “ESP/TCS
Indicator Light” will be illuminated. All other stability
features of ESC function normally. This mode is intended
to be used if the vehicle is in deep snow, sand or gravel
conditions and more wheel spin than ESC would nor-
mally allow is required to gain traction.
To turn ESC on again, momentarily press the “ESC Off”
switch. This will restore the normal “ESC On” mode of
operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off” mode by pressing the “ESC Off” switch. Once the situa-
tion requiring ESC to be switched to the “Partial Off”
mode is overcome, turn ESC back on by momentarily
pressing the “ESC Off” switch. This may be done while
the vehicle is in motion.
Full Off (Four-Wheel Drive Models Only)
This mode is intended for off-highway or off-road use
when ESC stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
pressing and holding the “ESC Off” switch for five
seconds when the vehicle is stopped and the engine is
running. After five seconds, the “ESP/TCS Indicator
Light” will illuminate and the “ESC OFF” message will
appear in the odometer. Press and release the Trip
Odometer button located on the instrument cluster to
clear this message.
In this mode, ESC and TCS, except for the “limited slip”
feature described in the TCS section, are turned off until
