The ignition can be turned off in an emergency even when travelling at a
speed of more than 2 km / hr.

twice within 1 second.
After emergency stop of the ignition, the steering is unlocked.
Brakes
Introduction
This chapter contains information on the following subjects:
Information on braking
143
Handbrake
144WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
The clutch pedal must be depressed when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the function of the brake booster may be impaired – risk of accident!
■
When leaving the vehicle, never leave persons who might, for example,
release the handbrake or take the vehicle out of gear unattended in the ve-
hicle. The vehicle could then start to move – risk of accident!
WARNINGIn the case of damage to the standard fitted front spoiler or if retrofitting
another front spoiler, hub caps etc. » page 173, Services, modifications and
technical alterations , make sure that the air supply to the front brakes is
not affected. The front brakes may overheat, which can have a negative im-
pact on the functioning of the braking system – there is a risk of an acci-
dent!CAUTION■ Observe the recommendations on the new brake pads » page 149.■Never let the brakes slip with light pressure on the pedal if braking is not
necessary. This causes the brakes to overheat and can also result in a longer
braking distance and excessive wear.
Information on braking
Read and observe
and on page 143 first.
If the brakes are applied in full and the control unit for the braking system con-siders the situation to be dangerous for the following traffic, the brake light
flashes automatically.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af- ter accelerating or driving off again.
Before travelling a long distance down a steep gradient, reduce speed and
shift into the next lowest gear. As a result, the braking effect of the engine will
be used, reducing the load on the brakes. Any additional braking should be
completed intermittently, not continuously.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv- ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
Under these severe conditions , the thickness of the brake pads must also be
checked by a specialist garage between services.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times.
Corrosion
Corrosion on the brake discs and dirt on the brake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking
system. The brakes are cleaned by applying the brakes several times.

Manual gear shifting is deactivated if more than 1 minute passes after either of
the -
/+ paddles was pulled. The temporary switch to manual gear shifting can
also be deactivated by pulling the right-hand + paddle towards the steering
wheel for more than 1 second.
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached.
If a lower gear is selected, the gearbox does not shift down until there is no risk of the engine over revving.
Note
It may be beneficial, for example, when travelling downhill, to use manual
shifting of gears. Shifting to a lower gear reduces the load on the brakes and
hence brake wear » page 143.

reached.
Kickdown
The kickdown function allows you to achieve maximum acceleration by your
vehicle while driving.
When the accelerator pedal is fully depressed, the kickdown function is activa-
ted in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed
and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has
reached its maximum revolutions for this gear range.

This function is only valid for some engines.
147Starting off and Driving
The display shows the following » Fig. 149 - .
The search area for the parking space on the driver's side is automatically indi- cated on the display.
Activate the turn signal on the driver's side if you wish to park on this side of
the road. In the display the search area for the parking space is indicated on
the driver's side.
If suitable parking space is found, its parameters are stored until another suit-
able parking space has been found or until a distance of 10 m had been driven
after finding the parking space.
If the driver changes the parking mode while searching for a parking space, the
symbol button must be pressed again.
Note
If the symbol
(km / h) is shown in the display , the vehicle speed should be
reduced below 40 km / hr (parallel parking) or below 20 km / hr (Transverse
parking) .

Automatic brake assist when speeding
If a velocity of 7 km / h is exceeded during the parking manoeuvre for the first time, the speed will be automatically reduced by the system to less than 7 km /
h. This prevents the parking manoeuvre from aborting.
Automatic termination
The system terminates the parking procedure if one of the following cases ari-
ses.
› A speed of 7 km / h is exceeded for the second time.
› The time limit of 6 minutes is exceeded.

The START STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.
WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.162Driving
Automatic engine shutdown takes place, segment display shows START STOP
ACTIVE or a check mark appears in the MAXI DOT display » Fig. 152 on
page 163 .
Automatic engine start›
Release the brake pedal.
The automatic start procedure takes place again.
Further information on automatic transmission
The automatic engine shut down takes place when the selector lever is in po-
sitions P, D , S and N and in Tiptronic mode.
When the selector lever is in position P, the engine remains shut down even
after you release the brake pedal. The engine starts automatically by pressing
the gas pedal or by moving the selector lever into a different mode and releas-
ing the brake pedal.
If the engine is off due to the automatic and the selector lever is put to the R
position, then the automatic start-up of the engine.
If the gear selector is moved from position R to the position D, S or N, the vehi-
cle must reach a speed of more than 10 km / h before the automatic engine
shutdown starts.
There is no automatic engine shutdown when the system detects a vehicle
moving due to a large steering angle.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when turning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
System related automatic start-up
Read and observe
on page 162 first.
When the engine is off, the system can automatically start the engine beforethe desired journey continues. Some possible reasons for this are:
› The vehicle has begun to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.

When start stop mode is deactivated, the warning light in the button illumi-
nates.
Note
If the system is deactivated when the engine is turned off automatically, then
the automatic start process takes place.

START MANUALLY
One of the conditions for automatic engine start is not satisfied or the driver's
seat belt is not fastened. The engine must be started manually.
On vehicles with the system KESSY the ignition is turned off by the first press
of the start button, only after pressing for the second time is the start process
initiated.
