AIR SUSPENSION SYSTEM (IF EQUIPPED)
The load leveling feature of the air suspension automatically keeps the
vehicle at a constant level if a load is added or removed from the vehicle.
This system maintains the vehicle height at a constant level by
automatically adding air or releasing air from the springs to offset
changes in vehicle loads.
When ever a door is opened (including the liftgate) the system
memorizes and maintains the height of the vehicle until all doors are
closed.
It is normal to hear a buzz or clicking from the air compressor on the
vehicle when the ignition is turned off. The system stays energized for 40
minutes after the ignition is turned off to compensate for any load
changes made after the vehicle is parked.
The air suspension shut-off switch is
located in the cargo area behind the
left rear quarter trim panel.
On vehicles equipped with
Air Suspension, turn OFF
the Air Suspension switch prior to
jacking, hoisting or towing your
vehicle.
Normal vehicle operation does not
require any action by the driver.

Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Drive at reasonable speeds (traveling at 105 km /h [65 mph] uses 15%
more fuel than traveling at 88 km/h [55 mph]).
²Revving the engine before turning it off may reduce fuel economy.
²Use of the air conditioner or defroster may reduce fuel economy.
²Use of speed control (if equipped) may improve fuel economy. Speed
control can help maintain a constant speed and reduce speed changes.
You may want to turn off the speed control in hilly terrain as
unnecessary shifting between third and fourth gears may occur and
could result in reduced fuel economy.
²Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
²Resting your foot on the brake pedal while driving may reduce fuel
economy.
²Combine errands and minimize stop-and-go driving.
Maintenance
²Keep tires properly inflated and use only recommended size.
²Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
²Use recommended engine oil. Refer toLubricant Specifications.
²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle Scheduled Maintenance Guide.
