WARNING (Continued)
● You must on no account unintentionally operate the throttle (e.g. by hand
from the engine compartment) if a drive position is engaged when the car is
stationary. The vehicle would otherwise immediately start off - also when the
handbrake is firmly applied - risk of an accident!
● You must move the selector lever into position P and firmly apply the
handbrake first before you or any other person opens the bonnet and starts
working on the engine when it is running - risk of accident! It is also essential
to observe all warnings ⇒ p age 150, Working in the engine compartment.
Selector lever lock
Automatic selector lever lock
With the ignition on, the selector lever is locked when it is in the positions P and
N. You must first of all depress the brake pedal in order to move the selector lever
out of this position. The warning light
cluster as a reminder for the driver when the selector lever is in the positions P
and N.
A time delay element ensures that the selector lever is not blocked when rapidly
switching over the position N (e.g. from R to D). This does, for example, allow one
to see-saw out a stuck vehicle. The selector lever lock will click into place if the
lever is in the N position for more than 2 seconds without the brake pedal being
pressed.
The selector lever lock is only active if the vehicle is stationary or moving at speed
of less than 5 km/hour. The lock is switched off automatically into position N
when the car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the handle of selector lever prevents certain selector lever
positions being engaged inadvertently. The selector lever lock is cancelled when
you press the Shiftlock button.
Keylock - Ignition key withdrawal lock
You can only withdraw the ignition key after switching off the ignition if the selec-
tor lever is in position P. If the ignition key is withdrawn, the selector lever is
blocked in position P.

Kickdown function
The kickdown function provides you with maximum acceleration
power.
Fully depressing the accelerator pedal allows the kickdown function to be activa-
ted in the desired driving program. This function has precedence over the driving
programme and serves for maximum acceleration of the vehicle when exploiting
the maximum power potential of the engine without taking into account the cur-
rent selector lever position (D, S or Tiptronic). The gearbox shifts down to one or
several gears in line with the driving state and the vehicle accelerates. The gear-
box does not shift up into the highest gear until the engine has reached its maxi-
mum revolutions for this gear range.
WARNING
Please note that using the kickdown function can result in the driven wheels
spinning on a smooth or slippery road surface - risk of skidding!
Dynamic shift programme
The automatic gearbox of your vehicle is controlled electronically. Shifting up and
down through the gears is performed automatically on the basis of pre-defined
driving programmes.
Adopting a moderate style of driving will cause the gearbox to select the most
economical driving programme. Shifting up into a higher gear as soon as possible
and shifting down as late as possible will have a favourable effect on your fuel
consumption.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and frequent changes in speed, exploiting the
top speed of the car or depressing the accelerator pedal (kickdown function), will
cause the gearbox to switch over to this style of driving and shift down earlier
with frequent changes in gears in comparison to the moderate style of driving.
Selecting the most appropriate driving programme for the particular style of driv-
ing is a continuous process. Irrespective of this it is, however, possible to switch or
shift down into a dynamic shift programme by depressing the accelerator rapidly.
The gearbox shifts down into a lower gear matching the speed of the car and this
allows you to accelerate rapidly (e.g. when overtaking) without having to depress
