When the kick-down switch (S16/6) is operated via the accelerator pedal a signal is passed on to the ETC 
control module (N15/3). Based on this information the ETC control module (N15/3) actuates the solenoid 
valves so that the upshifts and downshifts take place at higher engine speed.  

Shift-Lock Function 

Operation 

The term shift lock combines the functions which, in addition to the parking brake, offer an additional safeguard 
for the vehicle to prevent it moving off unintentionally. 

These include the functions of locking the selector lever position "P" and locking the ignition lock as well as the 
parking lock in the transmission. 

The shift lock function only allows shifting out of selector lever position "P" if the transmitter key (A8/1) has 
been turned into the position "Ignition: ON" and the brake pedal is depressed. 

In order to ensure that after parking the vehicle the selector lever is shifted into selector lever position "P", the 
transmitter key (A8/1) can only be turned towards "0" in this position and removed from the EZS control 
module (N73) (ignition lock locking, function). 

The vehicle is secured mechanically by blocking the park pawl gear. 

In the event of mechanical or electrical/electronic faults it is possible to unlock selector lever position "P" 
manually (shift lock override function).

One of the functions of the shift lock is to lock the selector lever in position "P". The selector lever is locked 
electronically. See Fig. 162

The selector lever remains disabled in position "P", if the brake is not operated or there is no power supply to 
the electronic selector lever module control module (N15/5) (circuit 87). 

The electronic selector lever module control module (N15/5) actuates the R/P lock solenoid valve (89) from the
