06 Starting and driving
Towing a trailer
electrical socket mounted near the trailer
hitch.
•
The function is automatically deactivated
when the trailer's wiring is disconnected
from the socket. The vehicle will then
accelerate normally.
NOTE
Since this function is activated when a con-
nector is plugged into the electrical socket
near the trailer hitch, it will be activated by
any electrical equipment (e.g. bicycle racks
with lighting, etc) that is plugged in, and will
remain active until the equipment is unplug-
ged from the socket.
Leveling
If your vehicle is equipped with automatic lev-
eling, the rear suspension always retains the
correct ride height regardless of the load.
06
•
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.
