Recreational Vehicle Towing
Recreational vehicle towing means towing the vehicle
behind another vehicle – such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as “dinghy towing” — towing the
vehicle with all four wheels on the ground, and “dolly
towing” — towing the vehicle with two wheels on the
ground and two wheels up on a device known as
a “dolly”.
The vehicle was not designed to be towed with any of
its wheels on the ground. If the vehicle must be
towed, see “Towing Your Vehicle” earlier in this section.
Notice: Towing an all-wheel-drive vehicle with all
four wheels on the ground, or even with only two of
its wheels on the ground, will damage drivetrain
components. Do not tow an all-wheel-drive vehicle
with any of its wheels on the ground.
Electronically Controlled Air
Suspension System
With this feature, an electronically controlled air
suspension system automatically keeps the vehicle level
as it is loaded and unloaded. The system includes a
compressor, two height sensors and two air springs
supporting the rear axle.
The system also has an internal clock to prevent
overheating if the inflator is used for prolonged periods.
If the system overheats, all leveling function stops
until the system cools down. During this time, the
indicator light on the air inflator switch will be flashing.
The ignition has to be on for the system to inflate,
in order to raise the vehicle to the standard ride height
after loading. The system can lower the vehicle to
the standard ride height after unloading with the ignition
on and also for up to 30 minutes after the ignition
has been turned off.
The compressor may be heard while it is operating
when the vehicle is being loaded, and periodically as the
system adjusts the vehicle to the standard ride height.
If the vehicle is parked for an extended period of
time, some bleed down of the suspension is normal.
Upon starting the vehicle, proper height will be achieved.
Overload Protection
The air suspension system is equipped with overload
protection. Overload protection is designed to protect the
air suspension system, and it is an indicator to the
driver that the vehicle is overloaded. When the overload
protection mode is on, it will not allow damage to the
air compressor. However, do not overload the vehicle.
See Loading the Vehicle on page 4-21.
