The dual brake system provides a reserve braking
capacity 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
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake
Force Distribution (EBD). In the event of an EBD failure, the Brake Warning Light will turn on along
with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the OFF
position to the ON/RUN position. The light should
illuminate for approximately two seconds. The light
should then turn off unless the parking brake is

112STARTING AND OPERATING
GUIDELINES FOR TRACK USE
NOTE:The standard Black Brembo Brake Pads are not
recommended for track use. Only the Red Brembo
Performance SRT brake pads are appropriate for
track use.
If your vehicle is equipped with Drive Modes,
they will alter the vehicle’s performance in
various driving situations. It is recommended
that your vehicle operates in SPORT or TRACK
modes during the track event.
Prior to each track event, verify all fluids are at
the correct levels.
Prior to each track event, verify the front and
rear brake pads have more than half pad thick -
ness remaining. If the brake pads require
changing, complete a brake burnish procedure
prior to track outing at full pace.
NOTE:Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
At the conclusion of each track event, it is
recommended that a brake bleed procedure is
performed to maintain the pedal feel and stop -
ping capability of your Brembo High Perfor -
mance brake system.
It is recommended that each track outing
should end with a minimum of one cooldown lap
using minimal braking.
It is recommended to check oil temperature
after each track session. If the oil is still above
225°F (107°C), do another cooldown lap if
possible, or keep the engine running and let idle
until below 225°F (107°C), in order to prevent
heat soaking of the engine. Ensure temperature
is reducing and do not leave vehicle gauges
unattended while idling just after a track
session.
It is recommended that the suspension system,
brake system, prop shaft, and half shaft boots
be checked for wear or damage after every track
event.
Track usage results in increased operating
temperatures of the engine, transmission, drive -
line and brake system. This may affect Noise
Vibration Harshness (NVH) countermeasures
designed into your vehicle. New components
may need to be installed to return the system to
the original NVH performance.
Tire pressure:
Recommended tire pressure of 33 psi
(230 kPa) when tires are cold, or below
42 psi (290 kPa) when hot.
NOTE:It is recommended that you target below 42 psi
(290 kPa) when tires are hot at the conclusion of
each track session. Starting at 33 psi (230 kPa)
cold and adjusting based on ambient and track
conditions is recommended. Tire pressure can be
monitored via the instrument cluster display and
can assist with adjustments.
Track burnishing your brakes
To avoid “green lining fade” during track use, the
brake pads and rotors must have a thermal
burnish for factory-installed components or when
new brake friction components are installed:

1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately
0.60 - 0.80g max without Anti-Lock Brake
System (ABS) intervention.

2. Complete one lap in this manner until you start smelling the brakes. Continue for another half
lap at speed, then complete a two lap
cooldown with minimal brake applications.
Ensure the brakes are not smoking. If they are,
complete another cooldown lap.
3. Getting the brakes to smoke is an indication that the brakes have overheated and may
negatively affect future track usage.

23_WD_OM_EN_USC_t.book Page 112

150STARTING AND OPERATING
7. When the N (Neutral) indicator light turns off, release the N (Neutral) button.
8. After the N (Neutral) button has been released, the transfer case will shift to the position
indicated by the selector switch.
9. Shift the transmission into PARK and turn the
engine off.
10. Release the brake pedal.
11. Disconnect vehicle from the tow vehicle.
12. Start the engine.
13. Press and hold the brake pedal.
14. Release the parking brake.
15. Shift the transmission into REVERSE or DRIVE, release the brake pedal, and check that the
vehicle operates normally.
DRIVING TIPS
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 conventional
passenger 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 passenger cars
any more than sports cars are designed to perform
satisfactorily in off-road conditions. 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.
OFF-ROAD DRIVING TIPS
When To Use 4WD Low — If Equipped
When off-road driving, shift to 4WD Low for
additional traction. This range should be limited to
extreme situations such as deep snow, mud, or
sand where additional low speed pulling power is
needed. Vehicle speeds in excess of 25 mph
(40 km/h) should be avoided when in 4WD Low.
Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that
must be considered before entering the water.
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your vehicle.
If you must drive through water, try to determine
the depth and the bottom condition (and location
of any obstacles) prior to entering. Proceed with
caution and maintain a steady controlled speed
less than 5 mph (8 km/h) in deep water to
minimize wave effects.
WARNING!
Do not drive in 4WD Low on dry pavement;
driveline damage may result. 4WD Low locks
front and rear drivelines together and does not
allow for differential action between the front to
rear driveshafts. Driving in 4WD Low on
pavement will cause driveline binding; use only
on wet or slippery surfaces.
CAUTION!
When driving through water, do not exceed
5 mph (8 km/h). Always check water depth
before entering as a precaution, and check all
fluids afterward. Driving through water may
cause damage not covered by the New Vehicle
Limited Warranty.

SERVICING AND MAINTENANCE269
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
Automatic Transmission Fluid (ATF) is an
engineered product and its performance may be
impaired by supplemental additives. Therefore, do
not add any fluid additives to the transmission.
Avoid using transmission sealers as they may
adversely affect seals.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating
conditions. Routine fluid level checks are not
required; therefore the transmission has no
dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Under normal operating conditions, the fluid
installed at the factory will provide satisfactory
lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer's specified
transmission fluid Úpage 307. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
FRONT/REAR AXLE FLUID
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected inspect the fluid level.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage your
transmission components. Such damage is not
covered by the New Vehicle Limited Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An authorized
dealer has the proper tools to adjust the fluid
level accurately.
CAUTION!
Using a transmission fluid other than the
manufacturer recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 307.
CAUTION!
Do not overtighten the plugs as it could damage
them and cause them to leak.
