Special Functions

SHIFT COMFORT CONTROL (Change of ignition timing)
With this type of control, the transmission control unit is connected to the Digital Motor Electronics (DME) control unit. At the shift point, the engine control unit reacts by retarding the ignition timing. This reduces engine torque during the shift process, thus increasing shift comfort and ensuring a long service life of the shift actuators.

If the signal is faulty, "emergency mode" is selected.

CREEP FUNCTION (MOVING OFF IN 2ND GEAR)
With this function, the vehicle moves off in shift position "D" and at a throttle angle < 35% in the automatic program and in 2nd gear in the manual program.

If the driver wants to move off in 1st gear, the throttle angle must be > 35% in the "D" shift position or position "3", "2" or "1" has to be preselected. In the manual program, 1st gear has to be selected to be activated.

NOTE: When moving off for the first time and while the engine is cold, the vehicle moves off in 1st gear.

EMERGENCY MODE
The electronic transmission control unit switches off the solenoid valves when specific signals or circuits become faulty and thus prevents gearshifts. If this occurs while the vehicle is in motion, 4th gear is selected regardless of the selector lever position and remains activated until the vehicle comes to a stop. When restarting the vehicle or after selecting reverse gear once, only third gear remains active.

A warning lamp in the clock displays this system fault and indicates that the electronic-hydraulic reverse interlock is inoperative. Take care never to move the shift lever to the "R" position while the vehicle is in motion.

ADAPTIVE PRESSURE CONTROL
Adaptive pressure control monitors the hydraulic shift pressures (modulating pressure) and adapts them to the transmission and driving status. This ensures good shift comfort throughout and increased service life of the shift actuators.

UPHILL AND DOWNHILL DETECTION
In addition to using driving mode data when selecting the shift mode map, the intelligent shift program also takes the driving resistance into account as resistance changes make themselves felt especially on gradients and downhill slopes.

This detection feature causes the system to shift into the map that provides the optimum gear for that particular gradient. This reduces gearshift frequency, allowing the engine braking effect to be used to better effect when driving downhill in a lower gear and therefore requiring less frequent braking.
