2-5. Driving information
l To maintain engine braking efficiency when driving on a long steep
downgrade, do not use the transmission in D.
Transmission shift range position must be in 5 in the S mode (6-
speed models) or in 4 in the S mode (5-speed models).
l Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
l Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and
result in reduced braking efficiency.
l 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 engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
(→P. 637)
l Always place wheel blocks under both the vehicle's and the
trailer's wheels when parking. Apply the parking brake firmly, and
put the transmission in P. Avoid parking on a slope, but if unavoid-
able, do so only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle's
and trailer's 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.
