Automatic gearbox
Automatic gearbox Information for driving with the 6-speed automatic gearbox The maximum speed is reached in the 5th gear. The 6th gear serves as an eco-
nomic driving programme, which is intended to reduce the fuel consumption.
Shifting up and down through the gears is performed automatically. You can also,
however, switch the gearbox over into the
Tiptronic mode. This mode makes it
possible for you to also shift gears manually ⇒ page 95.
Starting-off and Driving
– Depress the brake pedal fully and keep it depressed.
– Press the Shiftlock button (button in handle of the selector lever), move the
selector lever into the desired position, e.g. D ⇒ page 93, and then release
the Shiftlock button.
– Wait a moment until the gearbox has shifted (a slight engagement nudge can
be felt).
– Release the brake pedal and depress the accelerator ⇒ .
Stop
– The selector lever position N does not have to be selected when stopping just
for a short time, such as at a cross roads. It is sufficient to hold the vehicle sta-
tionary using the foot brake. The engine can, however, be allowed just to idle.
Parking
– Depress the brake pedal and hold it depressed.
– Apply the handbrake firmly.
– Press and Shiftlock button in the selector lever, move the selector lever to P
and then release the Shiftlock button.
The engine can only be started when the selector lever is in position P or N . If the
selector lever is not in the P or N positions when locking the steering, switching
the ignition on or off or when leaving the engine on, the following message will
appear in the Information display Move selector lever to position P/N! or, in the
instrument cluster display: P/N. It is sufficient to engage selector lever position
P when parking on a flat surface.
When parking on a slope you should first apply the handbrake firmly and then
move the selector lever into position P. This is to ensure that there is no excessive
pressure acting on the lock mechanism and that it is easier to subsequently move
the selector lever out of position P. If the selector lever is not in the P positin
when the driver's door is open and the ignition is switched off, or if it is not in the
P position when the ignition is switched off and the driver's door is opened, the
following message will appear in the Information display: Move selector lever to
position P! or, in the instrument cluster display: P. The message disappears af-
ter a few seconds by switching on the ignition or by moving the selector lever into
the position P .
If the selector lever position N is selected by accident while driving it is first nec-
essary to release pressure on the accelerator pedal and wait for idling speed of
the engine to be reached before engaging a drive position in the selector lever. WARNING
● Do not depress the accelerator when changing the position of the selector
lever if the car is stationary and the engine is running - risk of accident!
● Never move the selector lever into position R or P when driving - risk of an
accident!
● When the engine is running and the vehicle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (ex-
cept P and N) since the power transmission is never completely interrupted,
also not when the engine is idling - the vehicle creeps.
Information for driving with the automatic gearbox DSG The abbreviation DSG means Direct shift gearbox (Direct shift gear-
box).
Two independent clutches are needed for the power transmission between the
engine and the gearbox. These replace the torque converter of the conventional
automatic gearbox. Their shifting is matched in such a way that there are no jerks
when shifting the gear and the power transmission of the engine to the front
wheels is not interrupted. Shifting up and down through the gears is performed £ 91

Selector lever positions
Fig. 88 Selector lever/information display: Selector lever positions
The selector lever position you have engaged is shown in the information display
of the instrument cluster with the corresponding gear symbol highlighted
⇒ fig. 88 - on the right. In the positions D and S the gear you have already engag-
ed will be additionally displayed on the display.
P - Parklock
The driven wheels are locked mechanically in this position.
The Parklock must only be engaged when the vehicle is stationary ⇒ .
If you wish to move the selector lever into or out of this position, you must press
the Shiftlock button in the handle of the selector lever and at the same time de-
press the brake pedal.
R - Reverse gear
Reverse gear must only be engaged when the vehicle is stationary and the engine
idling ⇒ .
The brake pedal must be depressed and at the same time the Shiftlock must be
pressed, if you wish to obtain the selector lever positions R, P or N.
When the ignition is switched on and the selector lever is in position R, the re-
verse lights will come on.
N - Neutral
The transmission is in Neutral in this position. The brake pedal must be depressed (if the lever is in its position for longer than 2
seconds) in order to move the selector lever out of the position
N into the position
D, with the ignition switched on, on a vehicle travelling at less than 5 km/hour or
on a stationary vehicle.
D - Position for driving forward
When the selector lever is in this position, the forward gears are shifted up and
down automatically in line with engine load, vehicle speed and the dynamic shift
programme.
You must depress the brake pedal ⇒ if you wish to move the selector lever into
position D from N when the vehicle is travelling at less than 5 km/hour or is sta-
tionary.
In certain circumstances (e.g. when driving in mountainous regions or when tow-
ing a trailer) it may be beneficial to select the manual shift programme
⇒ page 95 for a short time in order to adapt the gearbox ratios manually to the
driving situations.
S - Position for sporty style of driving
Shifting up later into a higher gear makes it possible to fully exploit the power po-
tential of the engine. The gearbox also then shifts down at higher engine speeds
as in the position D .
The gearbox does not shift into the 6th gear in the position S, because the maxi-
mum speed is reached with the 5th gear 1)
.
The Shiftlock on the selector lever grip must be pressed when moving the selec-
tor lever out of the position D into the position S. WARNING
● Never move the selector lever into position R or P when driving - risk of an
accident!
● When the engine is running and the vehicle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (ex-
cept P and N) since the power transmission is never completely interrupted,
also not when the engine is idling - the vehicle creeps. £1)

Faults in the brake surface
If you notice that the braking distance has suddenly become longer and that the
brake pedal can be depressed further, it is possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist ga-
rage without delay in order to have the problem rectified. Drive at a reduced
speed while on your way to the dealer and adapt your style of driving to the high-
er brake pedal pressure required.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system. The
level of the brake fluid is monitored electronically
⇒ page 26, Brake system .WARNING
● Only apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in
jeopardy.
● When retrospectively mounting a front spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced oth-
erwise the braking system could run too hot.
● Allow for the fact that new brake pads do not achieve their full braking ef-
ficiency until approximately 200 kilometres. New brake pads must be first
“run in ”
before they develop their optimal friction force. You can, however,
compensate for this slightly reduced braking force by increasing the pressure
on the brake pedal. This guideline also applies to any new brake pads installed
at a future date. CAUTION
● Never allow the brakes to rub by applying slight pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a lon-
ger braking distance and excessive wear.
● Before negotiating a steep downhill section, please reduce your speed, shift
down into the next lower gear (manual gearbox) or select a lower driving stage
(automatic gearbox). This enables you to make full use of the braking power of
the vehicle and reduces the strain on the brakes. Any additional braking should be
done intermittently, not continuously. Note
The brake light flashes automatically in case of an emergency braking at speeds
greater than 60 km/h or with the intervention of the ABS, which lasts longer than
1.5 seconds. After the speed was reduced below 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 after accelerat-
ing or driving off again.
Brake booster The brake booster boosts the pressure which you generate with the brake pedal.
The necessary pressure is only generated when the engine is running.
WARNING
● Never switch off the engine before the vehicle is stationary.
● The brake booster only operates when the engine is running. Greater
physical effort for braking is required when engine is switched off. Because if
you do not stop as normal, this can cause an accident and severe injuries.
● While stopping or braking with a vehicle with a petrol engine and manual
transmission in the low rev range, press down on the clutch pedal. If you fail
to do so, the result may be an impairment of the function of the power brake.
You will apply a greater force to the brake pedal which you are usde to - dan-
ger of accident!
Antilock brake system (ABS) ABS prevents the wheels locking when braking.
General
The ABS contributes significantly to enhancing the active safety of your vehicle.
Compared to a car not fitted with the ABS brake system, you are able to retain op-
timal steering ability even during a full brake application on a slippery road surface
because the wheels do not lock up.
You must not expect, however, that the braking distance will be shorter under all
circumstances as a result of the ABS. The braking distance for example on gravel
and fresh snow, when you should anyway be driving slowly and cautiously, will be
longer. £ 131

Connecting negative terminal and engine block
–
Attach one end 3 to the negative terminal of the battery supplying the power
B .
– Attach the other end 4 to a solid metal part which is connected firmly to the
engine block, or to the engine block itself ⇒ .
Starting engine
– Start the engine of the vehicle providing current and run the engine at idling
speed.
– Now start the engine of the vehicle with the discharged battery.
– Interrupt the attempt at starting an engine after 10 seconds if it does not start
right away and wait for about 30 seconds before repeating the attempt.
– Disconnect the cables in exactly the reverse order they were connected. WARNING
● The non-insulated parts of the terminal clamps must never make contact
with each other. In addition, the jump-start cable connected to the positive
terminal of the battery must not come into contact with electrically conduct-
ing parts of the vehicle - risk of short circuit!
● Do not affix the jump starting cables to the negative terminal of the dis-
charged battery. There is the risk of detonating gas seeping out the battery
being ignited by the strong spark which results from the engine being started.
● Do not affix the cable end 4 to parts of the fuel and brake system.
● Run the jump-start cables so that they cannot be caught by any rotating
parts in the engine compartment.
● Do not bend over the batteries - risk of caustic burns!
● The vent screws of the battery cells must be tightened firmly.
● Keep any sources of ignition (naked flame, smouldering cigarettes etc.)
away from the battery - risk of an explosion!
● Never jump-start the batteries which have a too low electrolyte level - risk
of explosion and caustic burns! Jump-starting on vehicles with the “START-STOP” system
Fig. 148 Jump-starting on vehicles with
the START-STOP system
One vehicles with the “START STOP” system, the negative cable of the charger
must never be connected directly to the negative pole of the vehicle battery, but
only to the engine earth ⇒ fig. 148.
The vehicle General Vehicles with manual transmission can be towed in with a tow bar or a tow rope
or with the front or rear wheels raised.
Vehicles with automatic transmission can be towed in with a tow bar or a tow
rope or with the front wheels raised. If the vehicle is raised at rear, the automatic gearbox is damaged!
A tow bar is safest way of towing a vehicle and also minimizes any shocks. You
can use a tow rope only if a suitable tow bar is not available.
Refer to the following guidelines when towing:
Driver of the towing vehicle
– Release the clutch particularly gently when starting off or depress the acceler-
ator particularly gently if your vehicle is fitted with an automatic gearbox.
– On vehicles with manual transmission, only push down on the accelerator ped-
al once the rope is taught.
The maximum towing speed is 50 km/h. £ 179
