In order to maintain engine braking effi-
ciency when driving on a long steep
downgrade, do not use the transmis-
sion in "D". Select an appropriate shift
range in "S" mode (See "Automatic
transmission" on page 209 in Section
1−7).
D
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
30_C [85_F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to "If
your vehicle overheats" on page 497 in
Section 4.
D
Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in "P". Avoid park-
ing on a slope with a trailer, but if it
cannot be avoided, do so only after
performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release your brakes slowly until the
indicates
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into "P" and turn off the engine.
When restarting out after parking on a
slope:
1. With the transmission in "P" position,
start the engine. Be sure to keep the
brake pedal depressed.
2. Shift into gear.
3. Release the parking brake and brake
pedal, and slowly pull or back away
from the wheel blocks. Stop and apply
your brakes.
4. Have someone retrieve the blocks.
CAUTION
D
Do not use cruise control when you
are towing down long, steep grades
or with heavy loads.
D
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.
D
Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
