6. Release the parking brake only after the vehicle
being towed is firmly attached to the towing
vehicle. You can use your vehicle’s front mounted
receiver with the proper accessories to tow it.
See “Front Mounted Receiver” under If Your Vehicle
is Stuck in Sand, Mud, Ice or Snow on page 4-50.
7. Turn the ignition to ACCESSORY.
8. Disconnect the battery if you are going to tow for
long distances or long periods of time.
When towing your vehicle for extended periods of time,
start your vehicle as often as possible to prevent
battery drain. This should only be done when the tow
vehicle is parked.
Dolly Towing
Your vehicle cannot be dolly towed. If you must tow
your vehicle behind another, use the dinghy towing
procedure listed previously.
Notice: Dolly towing your vehicle will damage
drivetrain components. Do not dolly tow your
vehicle.
Selectable Extended Rear
Ride Height
If your vehicle has this feature it comes as part of the
electronically controlled air suspension system.
The selectable rear ride height allows you to raise the
rear of the vehicle about 2 inches (5 cm) over the normal
ride height. This can be helpful when driving off-road
where you may need more ground clearance to clear an
obstacle.
The button that controls this
feature is located on the
instrument panel to the
right of the steering wheel.
To use this feature, ensure that the following conditions
are met:
• The engine must be running.
• All doors must be fully closed. The suspension will
not raise or lower if a door is open.
• The vehicle speed must be less than 40 mph
(64 km/h). The system will not activate otherwise.
