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.
The Selec-Terrain switch will automatically change the
vehicle to the optimized height based on the Selec-Terrain
switch position. The vehicle height can be changed from
the default height for each Selec-Terrain mode by normal
use of the air suspension switches. Refer to “Four Wheel
Drive Operation” in “Starting And Operating” for further
information.
When To Use 4WD LOW Range 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
range.
WARNING!
Do not drive in 4WD-LOW Range on dry pavement;
driveline damage may result. 4WD-LOW Range locks
front and rear drivelines together and does not allow
for differential action between the front to rear drive-
shafts. Driving in 4WD-LOW on pavement will cause
driveline binding; use only on wet or slippery surfaces.
