2-5. Driving information

When driving
• As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increas ed. For each 10 mph (16 km/h) of
speed, allow at least one vehicle and trailer length.
• Avoid sudden braking as you may sk id, r
esulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
• Avoid jerky starts or sudden acceleration.
• Avoid jerky steering and sharp turn s, and slo
w down before making a
turn.
• Note that when making a turn, the tr ailer wheels will be closer than the
v
ehicle wheels to the inside of th e turn. Compensate by making a
larger than normal turning radius.
• Crosswinds and rough roads will ad v
ersely affect handling of your
vehicle and trailer, causing sway. Peri odically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If s
waying 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 vehi cle and trailer will stabilize.
• Take care when passing other vehicl es. P
assing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
• In order to maintain efficient engine br
aking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in “4”, in the “S” mode.
• Due to the added load of the traile r
, 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 engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. See “If your vehicle
overheats” ( P.359 ).
