Kickdown
Accelerator pedal pressed past the
pressure point: below certain speeds, the
transmission shifts down into a lower gear.
Full engine power is available for
acceleration.
Engine braking assistance from
motor
In order to utilize the engine braking
effect when driving downhill, select drive
range 3, 2 or, if necessary, 1 in good time.
The braking action is most effective in drive
range 1. If drive range 1 is selected at too
high a speed, the transmission remains in
second gear until the shift point for first
gear is reached, e.g. as a result of
deceleration.
Rocking the car
If it becomes necessary to rock the vehicle
to free it from sand, mud, snow or a hole,
move the selector lever from D to R in a
repeat pattern while simultaneously
applying light pressure to the accelerator
pedal. Do not race the engine and avoid
sudden acceleration.
This applies only to the exceptional
circumstances mentioned above.
Manoeuvring the vehicle
To manoeuvre the vehicle back and forth
during attempts to park or in garage
entrances, the vehicle's creeping
movement can be utilised by releasing
the brake pedal.
Never actuate accelerator and brake
pedals simultaneously.
