Quadra-Lift™ – If Equipped
When off-roading, it is recommended that the lowest

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 “Quadra-Lift™ – If Equipped” in “Starting and Oper-
ating” for further information.
When To Use 4WD LOW Range – If Equipped

Do not use 4WD LOW range when operating the
vehicle on dry pavement. Driveline hardware dam-
