Receptions of operation and auxiliary systems
Starting up and switching automatic transmission general information  | In the driver's pit footswitch should not be any objects that can restrict the freedom of movement of the pedals! When using non-standard rugs or mats need to ensure adequate progress of the pedals. |
The total load on the engine should be given only after the pre-heating it up to normal operating temperature, which occurs during movement fast enough. When starting off on slippery surfaces avoid prolonged any rotation of the wheels, as this may damage the power unit. Engine starting Description of the procedures run gasoline and diesel engines are given in section Engine cranks but will not start. Accelerates In order to unlock the selector lever AT depress the foot brake. Move the lever to position ?�D?� or ?�R?�.  | Do not rush, wait until the final inclusion of transfer, - said is especially true for the cold season. |
Release the parking brake - indicator lamp  the instrument cluster (see. graphic design of the instrument cluster). Release the brake pedal and gently depress the gas. Remember that petrol models with a cold engine automatic gear change occurs at slightly higher than normal engine speeds, thereby accelerating the process of warming up to normal operating temperature of the catalytic converter. When you activate the corresponding function on-board computer shortly after pulling the car from a place should occur automatic door lock. Switching control mode 5-speed automatic transmission Gear shifting while the vehicle automatically according to the selected gear position of AT mode transfer box ("H" or "L"), the degree of squeezing of the accelerator pedal and the current speed. Switching automatic transmission automatically adapt to individual driving style, due to gear shift points. The adaptation process is continuously taking into account the current values of the operating parameters of the power unit, the characteristics of movement, as well as action by the driver. Information about selected AT gear is displayed in the appropriate field of the homepage multifunction display (see. Illustration Arrangement base page fields display multifunction display on-board computer). The description of procedures and start the engine of the car pulling away from the place given in the previous sections (see. Above). When traveling, keep in mind that moderate squeezing gas pedal provides earlier switching the transmission to a higher gear, while under strong pressure switch occur later. Squeezing the throttle pedal to the floor (to the point of overcoming resistance) automatically switches to a lower gear AT mode (kickdown), providing enhanced dynamic qualities of the car. When the pedal is returned to the original transmission higher gear that meets the characteristics of this high-speed mode. When a temporary halt not output from the selector lever to position ?�D?�, keeping the car stationary using the foot or handbrake. When maneuvering in tight spaces, adjust the speed of the gradual releasing the foot brake. Try lightly squeeze the gas pedal and do not "play" with it. When towing a trailer in hilly terrain select mode restrictions AT (2 or 3, depending on the steepness of the slopes), on particularly dangerous stretches activate lowering (?�L?�) mode of the transfer case. AT selector lever with an electronic selector module equipped with sequential shift function operating ranges mode ?�D?� | When driving on a slippery road surface should not produce inhibition of transmission due to the activation mode restrictions ("3", "2" or "1"), as this may lead to loss of traction! Remember that the engine brake is always associated with a sharp increase in its turns, is fraught with serious internal injuries of the power unit. |
 | Provisions range selector lever AT (Indication of the switching output in the corresponding field of the homepage multifunction display, see. Section Brake Assist (BAS)) |
The transmission range selector lever can be in one of four fixed positions. Starting is only possible in the positions ?�P?� or ?�N?� of the lever. If the stop is made when the AT is in the range of motion ?�D?�, in either ?�N?�, it is necessary to fully release the accelerator pedal and the brake pedal to squeeze reliable braking of the vehicle. When switching to the AT arm move along the guide groove. When removing the key from the ignition switch the selector lever locked in position "P". In this case, the output of the lever from the "P" is not possible even when squeezing the brake pedal. Procedure emergency stop lever lock below. To avoid breakage AT translate the lever in position "P" only after the vehicle is stopped. | Removing the key from the ignition becomes possible only after the transfer of the selector lever to position "P" and the foot brake pedal is released. |
The standard range The position "P". In this position, the selector lever is blocked transmission that provides additional protection of the car parked. Always translate the selector lever to position "P" when you turn off or the engine is started. To display range selector lever from position "P", it is necessary to squeeze the brake pedal, pre-releasing the gas pedal. Reject the selector lever to the right and remove it from position "P". The position ?�R?�. Methods of control range selector lever when transferring it from the position "P" position ?�R?� (Reverse) as described above. Turning the lever to position ?�R?� of the position ?�N?� (neutral) is made only after a full stop of the car - in case of failure, depress the brake pedal and slowly move the lever, first back to position ?�N?�, then to ?�R?�. The position ?�N?�. Use the position ?�N?� (Neutral) when starting the engine stalled on the go and at short stops the car with the engine running. If you for some reason need to move away from the vehicle, pre-set the range selector lever to position "P". In the derivation of the lever out of position ?�N?� foot brake pedal is depressed. | Translation transmission in position ?�N?� of the movement associated with the risk of serious internal damage to the gearbox! Use this position only when the threat of drift of the car when driving on a slippery road surface with disabled protivozanosnoy system (ESP), as well as the need to connect the transfer case. |
Position ?�D?�. In this position the range selector lever must be constantly at car movement in normal driving conditions, - it provides automatic switching between AT five forward gears in accordance with changes in speed limits and the degree of squeezing gas pedal. For sharp dispersal of the car when the transmission in the range of ?�D?� depress the pedal to the metal. This transmission will automatically switch to an adjacent lower transmission mode (kickdown). | If the drive speed is low, switching may occur by two notches down. |
The ranges for the movement under special conditions When the position "D" is provided for manual transmission shift within a range for movement in particular conditions ("4", "3", "2" and "1").  | Emergency unlock the selector lever in position "P" |
Easy push-lever to the left (?�D-?�) leads to a transition to an adjacent down-AT range. If you hold the lever in position ?�D-?� switches the transmission into the range that provides optimum dynamic performance of the car in accordance with the current active transmission. Information on changes in the ranges displayed in the display field on the face of the tachometer to the left of the clock display. | When push-ups lever to ?�D-?� while driving with an excessively high speed switching mode of transmission is blocked in order to prevent an unacceptable increase in engine speed. |
Squeezing the lever to position ?�D +?� leads to a shift in the transmission adjacent to the current higher range. Holding the lever in position ?�D +?� allows a return to the standard mode ?�D?�. | When the step-down mode (?�L?�) transfer box motor protection is performed by locking switch into higher gear. |
Position "4". If the range selector lever is switched to "4", automatic transmission functions similarly to the case enable the range of ?�D?�. The difference is that the shift is eliminated the fifth speed gear. The position "3". In this position, move shift transmission limited to third gear. The mode can be used for engine braking. Comprising a range of "3" is also useful to eliminate unnecessary cycle through the automatic transmission between the third and fourth gears - like cyclic shift gearbox can be observed, for example, when driving in heavy traffic with frequent stops and slowdowns. Position "2". When the range of "2" automatic transmission will constantly work on the second transfer. We recommend using this limit when towing a trailer in hilly terrain or for engine braking on downhill slope significantly. When you stop the car the gearbox does not go into first gear. The constant switch second gear provides good traction dynamics of the car on the climbs and the possibility of intensive engine braking on steep descents. The range of "2" can also be used when starting off on a slippery road surface or when driving in deep snow, helping to prevent severe slippage of the drive wheels of the vehicle. It is recommended to use a range of "2" when driving on steep mountain passes, driving with a trailer in hilly terrain, as well as for engine braking on steep descents especially. "1". When the range of "1" automatic transmission will constantly work on the first transfer. If the inclusion of a range of "1" is produced at a speed of over 50 km / h, the first mission will switch to second gear. Turning the intermediate stage eliminates the sharp and unexpected engine braking. The mode can be used when driving with a trailer on particularly steep descents and long passes. Emergency unlock the selector lever in position "P" The need to unlock the AT selector lever in position "P" appears in the case of failure of the locking mechanism, as well as when you want to tow a faulty car. The trip can be done using a conventional ball-point pen or any other object suitable shape. Depressing the cap, enter the pen into the hole under the dashboard selector switches and pressing it down, output lever from the parking position. Remove the pen. | To return to the place of the plug gently push the lever in the direction of the position ?�D?�. |
Emergency mode On the transition of transmission in emergency mode operation indicate deterioration of the dynamic characteristics of the car and the transmission failure by switching. There is a possibility to switch to 2nd gear or reverse gear. In such a situation, you should stop moving, park in a safe location, move the selector lever to position "P" and turn off the engine. Wait at least 10 seconds, re-start the engine and move the selector lever in position ?�D?�, - turn 2nd gear. Translation of the lever to position ?�R?� leads to a reverse gear. The car should immediately drive off to the nearest service station Mercedes-Benz for detailed diagnosis of AT and perform necessary regenerative repair.
