Driving tips
8-38
D If your vehicle has an automatic transmission,
avoid using the accelerator pedal to stay stationary
on an uphill slope instead of using the parking brake
or foot brake. That may cause the transmission fluid
to overheat. Also, if your vehicle is equipped with an
automatic transmission, avoid driving with the gear
selector lever in “D” when towing a heavy trailer to
prevent fluid overheating. A lower gear should be
used.
B Parking on a grade
Always block the wheels under both vehicle and
trailer when parking. Apply the parking brake firmly.
You should not park on a hill or slope. But if parking
on a hill or slope cannot be avoided, you should
take the following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks under both
the vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb the
load.
4. Apply the regular brakes and then apply the
parking brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmis-
sion) or “P” (automatic transmission) and shut off the
engine.
