Individual gears are engaged automatically depending on the position of the gear selector lever, the position of the program switch, the driving speed, and the position of the accelerator pedal.
Using the automatic transmission selector lever and program switch, the automatic shifting process can be adapted to the operating conditions.
Automatic transmission selector lever positions
Position "P"
Parking lot blocking.
Select only when the car is parked (before moving the selector lever to position P, the parking brake must be applied). The gearbox is automatically locked to prevent the vehicle from rolling away.
Attention! The automatic transmission selector lever can be moved to position P only when the key in the ignition switch is turned to position 2 and the service brake is applied. The key can only be removed from the ignition switch if the automatic transmission selector lever is in position P.
Position "R" Reverse gear
Select only when the vehicle is parked and the engine speed is idling.
Position "N" Neutral position
In this position, there is no transmission of torque from the engine to the drive axle. When the brakes are released, the car moves freely. Select only when the vehicle has come to a complete stop, unless the vehicle is sliding or is in danger of skidding.
Position "D"
Shifting to a higher gear - up to 4th gear. For all normal road conditions.
Position "3". This position is used to create additional power when driving downhill on a moderate incline and for engine braking when driving downhill on a moderate incline.
Position "2".For driving on medium ascents and descents. The engine braking effect can be used up to the maximum permissible engine speed in 2nd gear.

Position "1".This position is used when driving downhill on a steep incline or for engine braking at low speeds while descending a mountain.
Note: This position can be used for maximum engine braking. Avoid sudden gear shift 1. Sudden engine braking may cause skidding. Turn on this position based on road conditions and vehicle speed.
