Traction Assist
Your vehicle may be equipped with the optional
TM
Traction Assist system. This system helps prevent
wheel spin in order to improve tire traction and is
an especially useful feature when you drive in hilly
areas or on slippery, icy or snowy roads.
TM
Traction Assist works automatically by rapidly
applying and releasing the brakes to prevent one or
both of the rear drive wheels from spinning during
acceleration.
During the Traction Assist
often occurs during low speed acceleration on
slippery surfaces, a noise may be heard coming from
the engine compartment. This is normal and may
last for a few seconds during the acceleration of the
vehicle.

If the Traction Assis; system is cycled excessively,
the system will shut down to prevent the rear
brakes from overheating. A cooling down period is
required to prevent damage to the brakes. This time
period varies and depends on brake usage during
the cooling down period. Anti-Lock braking is not
affected and will function normally during the cool
down period.
After the cool down period, the Traction Assist
function is restored.%
Rear Air Suspension System
Your vehicle is equipped with an automatic load
leveling rear air suspension system. This system
maintains the rear vehicle height at a constant level
by automatically adding air or releasing air from the
rear air springs to offset changes in vehicle loads.
