Moving up a steep grade from a standing start
To move up a steep grade from a standing start, depress the brake pedal, shift the shift lever to D (Drive). Select the appropriate gear depending on load weight and steepness of the grade, and release the parking brake. Depress the accelerator gradually whilst releasing the service brakes.
When accelerating from a stop on a steep hill, the vehicle may have a tendency to roll backwards.

When you start driving after the car was stopped on a hill, even though the shift lever is in D (Driving) position, if you do not step on the accelerator pedal or brake pedal, the car may roll backward, resulting in a fatal accident.
Always come to a complete stop before shifting into D (Drive).
