310 OperationDriving tips
4
If possible, do not brake abruptly, but
rather engage the brake slightly at first
to permit the trailer to activate its brake.
Then increase the braking force.Warning
G
Take into consideration that when towing
a trailer, the handling characteristics are
different and less stable from those when
operating the vehicle without a trailer.
It is important to avoid sudden maneu-
vers. Sudden maneuvers may lead to loss
of control over the vehicle-trailer combi-
nation. This could cause an accident re-
sulting 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 the
engine overloading and / or over-
heating.
When going down a long hill, shift
into a lower gear and use the en-
gine’s braking effect. Avoid riding the
brakes, thus overheating the vehicle
and trailer brakes.
If the engine coolant rises to an ex-
tremely high temperature (coolant tem-
perature needle approaching the red
zone) when the air conditioner is on,
turn off the air conditioner. Engine cool-
ant heat can be additionally vented by
opening the windows, switching the cli-
mate control fan speed to high and set-
ting the temperature control to the
maximum hot position.
Extreme care must be exercised since
your vehicle with a trailer will require ad-
ditional passing distance ahead than
when driving without a trailer. Because
your vehicle and trailer is longer than
your vehicle alone, you will also need to
go much farther ahead of the passed ve-
hicle before you can return to your lane.
