 – P

When the P button is pressed, the drive
wheels are locked. Only press P when the ve-
hicle is stationary ››› .
T o pr

ess the P button you must press the
brake pedal simultaneously.
 – Reverse gear
Reverse gear must be engaged only when
the vehicle is stationary and the engine is
idling ››› .
T o engage r

everse gear R, you must press the
brake pedal simultaneously. The reverse
lights switch on when the reverse gear R is
selected and the ignition is on.
 – Neutral
In this position, the gear is in neutral.
Press the brake pedal to move the lever from
N to D/S when the vehicle is stationary or at
speeds below 3 km/h (2 mph) ››› .

orward drive position
The D/S position enables the gears to be op-
erated in normal mode (D) or sport mode (S).
To select Sport mode S, move the lever back-
wards. Pushing the lever again will select nor-
mal mode D. The selected driving mode is
displayed on the instrument panel screen.
In normal mode (D), the gearbox selects the
best gear ratio. This depends on the engine load, the road speed and the dynamic gear
control pr

ogramme (DCP).
Sport mode (S) should be selected for a
sporty driving style. This setting makes use of
the engine's maximum power output. When
accelerating the gear shifts will be noticea-
ble.
Under certain circumstances (e.g. on moun-
tain roads) it can be advantageous to switch
tiptronic mode ››› page 231
, to adapt the
gears to suit the road conditions.
Selector lever lock
In N, the lever lock prevents a gear range
from being engaged, and prevents the vehi-
cle from moving off accidentally.
Press and hold the brake pedal with your left
foot with the engine running.
As a reminder to the driver, when the lever is
in position N the following indication will be
shown on the screen:
When stationary, apply footbrake
while selecting a gear.
The lever is not locked if it is moved quickly
through position N (e.g. when shifting from R
to D). This makes it possible, for instance, to
“rock the vehicle backwards and forwards” if
it is stuck in snow or mud. The lever lock en-
gages automatically if the brake pedal is not
pressed and the lever is in position N for more than about one second at a speed of less
than 5 km/h (3 mph). WARNING

If the Auto Hold function was not switched on,
it will automatically remain off next time the

The Auto Hold function connects automat-

(all points must be met at the same time
››› ):
The v ehicl

e is kept stationary with the
brake pedal on a flat surface or on a
slope.
The engine rotates “correctly”.
The Auto Hold function is automatically
turned off if the following conditions are
met: If any of the conditions mentioned on

the vehicle stationary with the Au-

If the engine is running irregularly or an

The smart technology incorporated into
the Aut o Hol

provided by the Auto Hold function should
never tempt you to take any risk that may
compromise safety.

Practical tips
Energy management Optimisation of the st ar
ting ca-
pacity The power management controls the distri-
bution of el
ectrical ener

gy and thus helps to
ensure that there is always enough power
available to start the engine.
If a vehicle with a conventional electrical sys-
tem is left parked for a long time, the battery
will gradually lose its charge because certain
electrical devices, such as the electronic
gearbox lock continues to draw current even
when the ignition is off. In some cases there
may not be enough power available to start
the engine.
Your vehicle is equipped with an intelligent
power management system to control the
distribution of electrical energy. This signifi-
cantly improves reliability when starting the
engine, and also prolongs the useful life of the
battery.
The main functions incorporated in the power
management system are battery diagnosis,
residual current management and dynam-
ic power management.
Battery diagnosis
The battery diagnosis function constantly
registers the condition of the battery. Sensors detect the battery voltage, battery current
and batt
ery t

emperature. This enables the
system to calculate the current power level
and charge condition of the battery.
Residual current management
The residual current management reduces
power consumption while the vehicle is
parked. It controls the supply of power to the
various electrical devices while the ignition is
switched off. The system takes the battery di-
agnosis data into consideration.
Depending on the power level of the battery,
switch off the individual electrical devices
one after the other to prevent the battery
from losing too much charge and to ensure
that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function dis-
tributes the available power to the various
electrical devices and systems according to
their requirements. The power management
ensures that on-board systems do not con-
sume more electrical power than the alterna-
tor can supply, and thus maintains the maxi-
mum possible battery power level. Note
