SUSPENSION CONTROL SYSTEM
Outline
• The self-leveling suspension is a system that adjusts the vehicle height according the amount of vehicle load.
This system will raise the rear of a vehicle, lowered due to a load placed on it, to the designated load level
the vehicle has been driven a certain distance.
• The vehicle height adjustment is performed using a gas-pressurized pump function built into the rear shock
absorber.
• For the vehicle height to return to the designated load level, the vehicle must be driven approx. 5—6 km {3.1—
3.7 miles} in city driving conditions. (Distance will vary due to load and road conditions.)
• A load amount of approx. 140—300 kg {308—660 lb} at the rear axle will cause the vehicle height to be raised,
and any weight over that will prevent the vehicle from returning to the designated load level.
*
: Designated load level is defined as the level at which the vehicle is with: a full fuel tank; engine coolant and oil at
specified levels; spare tire, jack and tools in designated positions; and four people, weighing 55 kg {121 lb} each,
riding in the vehicle.
