WARNING!
Take into consideration that when towing a trail-
er, the handling characteristics are different and
less stable from those when operating the vehicle
without a trailer.
It is important to avoid sudden maneuvers.
Sudden maneuvers may lead to loss of control
over the vehicle-trailer combination. This could
cause an accident resulting in property damage or
injury to you or others.
CAUTION!
If the transmission hunts between gears on
inclines, manually shift to a lower gear (select
"4",
"3", "2" or
"1"). A lower gear and reduction of
speed reduces the chance of engine overloading
and / or overheating.
When going down a long hill, shift into a lower
gear and use the engine’s braking effect. Avoid
riding the brakes, thus overheating the vehicle
and trailer brakes.
If the engine coolant rises to an extremely high
temperature (coolant temperature needle
approaching the red zone) when the air
conditioner is on, turn off the air conditioner.
Engine coolant heat can be additionally vented by
opening the windows, switching the climate
control fan speed to high and setting the
temperature control to the maximum hot position.
