Management of automatic transmission (AT)
On the considered cars 4-staged AT controlled by an electronic control unit is established. The lever of the selector of the AT modes is located in the lower part of the central console.
All transfers of advance switches automatically if the lever of the selector of the AT modes is in situation "D".
For movement of the lever of the selector from situation "P" ignition has to be included, the brake pedal is squeezed out, and also the fixing removal button is pressed.
For the smooth movement squeeze out a brake pedal when moving the lever of the selector of situation "N" in provisions of advance or back.
The description of the switch of the AT modes ("POWER"/" SNOW) is provided in the Section Governing bodies and the equipment of salon.
AT operating modes
"P" (Parking) — In this provision of AT is blocked, and forward wheels cannot rotate. Before transferring the selector lever to this situation, completely stop the car.
"R" (The movement by a backing) — This position of the lever of the AT selector is used for the movement back.
"N" (Neutral situation) — Wheels and transmission are not blocked, the car can be moved freely even if the transfer case is installed on transfer.
"D" (Movement) — Normal position of the lever of the selector at the movement of the car. AT switches between all four transfers of advance, proceeding from an optimum ratio of power and economy of fuel.
"2" (The second transfer) — AT switches only between the 1st and 2nd transfers of advance. It is used for obtaining bigger power at the movement on rise, and also for braking by the engine at the movement on descent. The choice of this situation also helps to reduce wheel slip on the slippery road. The top limit of speed of the movement at the chosen 2 mode makes 117 km/h.
— Install "L" (The lowering transfer) the selector lever in this situation at big loading, and also at the movement on the steep slope. The top limit of speed of the movement at the chosen L mode makes 65 km/h.
The movement on the steep slope from the place
To start the movement on the steep slope squeeze out a brake pedal, move the AT selector lever to situation "D", "2" or "L" (depending on loading of the car and the steepness of rise) and release the parking brake. Smoothly press the accelerator pedal, releasing a brake pedal.
Use the O/D mode to start the movement on slippery roads, at the movement on rise, and also for braking by the engine at the movement on descent.
When using the O/D mode the gear shifting algorithm at advance in the chosen D mode changes. For inclusion of the O/D mode press the switch located on the AT selector lever handle, - has to light up corresponding To/L in a combination of devices. For switching off of the O/D mode press the switch once again, - To/L has to go out.
At the switched-off O/D mode will hold the 3rd transfer in the D mode of AT and will never switch to the 1st and 4th transfers. When braking the 2nd transfer then AT comes back to the 3rd transfer for smooth acceleration joins. Respectively, at a start of motion (from the place) the 2nd transfer is used, and then AT switches to the 3rd transfer.
Blocking of switching and emergency movement of the lever of the selector from situation "P"
For safety of the driver and passengers of AT it is equipped with system of the blocking preventing movement of the lever of the selector from situation "P" if the brake pedal is not squeezed out.
For movement of the lever of the selector squeeze out of situation "P" and hold a brake pedal. Then start the engine or turn the ignition key in the provision of "ON", press the selector lever clamp located on its handle, and move the lever to required position. As well for extraction of a key from the ignition lock the lever of the selector has to be in situation "P".
If when performing of the actions described above it was not succeeded to move the selector lever from situation "P", without releasing a brake pedal, remove a cap from the button of emergency removal of blocking, press this button and move the lever from situation "P".
