trailer brake controller to check that
the trailer brakes work. During the
trip, occasionally check that the load
and trailer are secure and that the
lamps and any trailer brakes are
working.
Towing with a Stability Control
System
When towing, the stability control
system might be heard. The system
reacts to vehicle movement caused by
the trailer, which mainly occurs
during cornering. This is normal when
towing heavier trailers.
Following Distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving without a trailer. This can help
to avoid heavy braking and sudden
turns.
Overtaking
More overtaking distance is needed
when towing a trailer. The
combination of the vehicle and trailer
will not accelerate as quickly and is
much longer than the vehicle alone.
You need to drive much farther
beyond the overtaken vehicle before
turning back into the lane. Overtaking
on level roadways. Avoid overtaking
on hills if possible.
Reversing
Hold the bottom of the steering wheel
with one hand. To move the trailer to
the left, move that hand to the left. To
move the trailer to the right, move
that hand to the right. Always reverse
slowly and, if possible, have someone
guide you.
Making Turns
Caution
Turn more slowly and make wider
arcs when towing a trailer to
prevent damage to your vehicle.
Making very sharp turns could
cause the trailer to make contact
with the vehicle.
Make wider turns than normal when
towing, so the trailer does not go over
soft shoulders, over kerbs, or collide
with road signs, trees, or other objects.
Always indicate turns well in advance.
Do not steer or brake suddenly.
Driving on Grades
Reduce speed and change to a lower
gear before starting down a long or
steep downhill grade. If the
transmission is not shifted down, the
brakes may overheat and result in
reduced braking efficiency.
The vehicle can tow in D (Drive). Shift
the transmission to a lower gear if the
transmission shifts too often under
heavy loads and/or hilly conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off immediately
after towing at high altitude on steep
uphill grades, the vehicle could show
signs similar to engine overheating. To
avoid this, let the engine run,
preferably on level ground, with the
transmission in P (Park) for a few
minutes before turning the engine off.
If the overheat warning comes on, see
Engine Overheating 0 299.
