Starting and operating
and stop the vehicle at the nearest safe place. Refer to Engine Over-
heat section (chapter 8), and Warning and Indicator Lights section
(chapter 3) in the owner's manual.
D If your vehicle has a automatic transmission, avoid using the accel-
erator pedal to stay stationary on an uphill slope instead of using the
parking brake or foot brake. This may cause the transmission fluid to
overheat. Also, if your vehicle is equipped with an automatic transmis-
sion, avoid driving with the gear selector lever in "D" when towing a
heavy trailer to prevent fluid overheating.
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 transmission) or "P" (auto-
matic transmission) and shut off the engine.
