●
Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway. Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the steering or brakes, your vehicle and
trailer will stabilize.
●
Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you have plenty of room before changing
lanes.
●
To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not use the transmission in
D (vehicles with an automatic transmission) or 5 (vehicles with a
manual transmission).
●
Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the high engine coolant temper-
ature warning light flashes or comes on overheating, immediately
turn off the air conditioning (if in use), pull your vehicle off the road
and stop in a safe place. (
