DRIVING TIPS
On-Road Driving Tips
Utility vehicles have higher ground clearance and a nar-
rower track to make them capable of performing in a wide
variety of off-road applications. Specific design character-
istics give them a higher center of gravity than conven-
tional 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 conven-
tional passenger cars any more than low-slung 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
NOTE:Prior to off-road driving with non-Summit models
that are also equipped with an Off Road Package, remove the
lower fascia to prevent damage. The lower fascia is attached
to the lower part of the front fascia with seven quarter turn
fasteners and can be removed by hand. The front license
plate bracket must be removed first if equipped.
NOTE: On Summit models the lower front fascia is not
removable.
Lower Front Fascia Removal:
1. Remove the seven quarter turn fasteners.
2. Starting on one side of the vehicle, disengage lower fascia from the upper fascia. Grasp the portion inside
the wheel well. Pulling it downwards and toward you,
separate the tabs from the slots in the upper fascia.

3. Continue working your way across the vehicle, separat-ing the remaining tabs from the slots in the upper fascia.
NOTE: Do not allow the lower fascia to freely hang from
the tabs in the opposite corner as damage to lower and
upper fascia may result.
4. Store the lower fascia in a safe location.
NOTE: It is recommend to also remove the radar sensor on
vehicle equipped to Adaptive Cruise Control (ACC). This
radar sensor is specifically calibrated to your vehicle and is
not interchangeable with other radar sensors.
Radar Sensor Removal Procedure (If Equipped With
Adaptive Cruise Control [ACC]):
1. With the lower fascia removed, which provides access to the sensor and bracket, disconnect the wiring harness
from the sensor.

NOTE: If you receive a fault, see your authorized dealer
they may need to perform a sensor alignment. Lower Front Fascia Installation
NOTE:
This will only work if you have a helper.
1. Starting at the center of the vehicle, engage a sufficient number of tabs to support the weight of the lower fascia
(typically one or two tabs) into the upper fascia.
2. Working your way outward, engage the tabs into the slots on one side of the vehicle.
3. Return to the center of the vehicle and repeat Step 2 to the opposite side of the vehicle.
NOTE: •It may be necessary to apply additional force to
individual tabs to make sure they are fully engaged.
• Do not use any tools to apply additional force to the
tabs as damage to the upper and lower fascias may
result.
4. Reinstall the seven quarter turn fasteners.
Quadra-Lift — If Equipped
When off-roading, it is recommended that the lowest
useable vehicle height that will clear the current obstacle or
terrain be selected. The vehicle height should then be
raised as required by the changes in terrain.

WARNING!
•Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. Using the
wrong type of brake fluid can severely damage your
brake system and/or impair its performance. The
proper type of brake fluid for your vehicle is also
identified on the original factory installed hydraulic
master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der reservoir cap secured at all times. Brake fluid in
a open container absorbs moisture from the air
resulting in a lower boiling point. This may cause it
to boil unexpectedly during hard or prolonged brak-
ing, resulting in sudden brake failure. This could
result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
(Continued)
WARNING! (Continued)
•Do not allow petroleum based fluid to contaminate
the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.
Automatic Transmission
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. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE: No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
