Parking on an Incline
A rolling vehicle can result in serious injury. Avoid parking on an
incline. If parking on an incline is unavoidable, follow these
precautions:
1. Place the transmission in PARK.
2. Turn the engine off.
3. Block the rear wheels on the downhill side, or park the vehicle in a
sidehill position instead.
