06 Starting and driving
Towing a trailer
WARNING
•
Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•
Trailer hitches attaching to the vehicle
rear axle must not be used.
•
Never connect a trailer's hydraulic
brake system directly to the vehicle
brake system, nor a trailer's lighting
system directly to the vehicle lighting
system. Consult a trained and qualified
Volvo service technician for correct
installation.
•
When towing a trailer, the trailer's
safety wire must be correctly fastened
to the hole or hook provided in the
trailer hitch on the vehicle. The safety
wire should never be fastened to or
06
wound around the drawbar ball.
Leveling
If your vehicle is equipped with automatic lev-
eling, the rear suspension always retains the
correct ride height regardless of the load.
•
The system adjusts the rear suspension
to the correct level after the vehicle has
been driven a short distance.
•
When the vehicle is stationary, the rear
suspension lowers, which is normal.
