2-5. Driving information

When driving
lCrosswinds 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 vehi-
cle 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.
lTake care when passing other vehicles. Passing 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.
lIn order to maintain engine braking efficiency when driving on a long
steep downgrade, do not use overdrive. Transmission shift range posi-
tion must be in 4 in S mode.
lDue to the added load of the trailer, your vehicle's engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when driving up
a long or steep grade. If the engine coolant temperature gauge indi-
cates overheating, immediately turn off the air conditioning (if in use),
pull your vehicle off the road and stop in a safe spot. (→P. 587)
lAlways place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into P and turn off the engine.
