Automatic gearboxAutomatic gearbox*Information for driving with the 6-speed automatic gearbox*
Your car is equipped with a conv entional 6-speed automatic gearbox.The maximum speed is reached in the 5th gear. The 6th gear serves as an economic
driving programme, which is intended to redu ce the fuel consumption. Shifting up and
down through the gears is performed automa tically. 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 120.Starting-off and Driving– Depress the brake pedal fully and keep it depressed.
– Press the Shiftlock button (button in ha ndle of the selector lever), move the
selector lever into the desired position, e.g. D page 118, and then release the
Shiftlock button.
– Wait a moment until the gearbox has shif ted (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 absolutely sufficient to hold the stopped
vehicle stationary by depressing 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
page 108.
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 position N is selected by accident while driving it is first necessary
to release pressure on the accelerator pedal and wait for idling speed of the engine to
be reached before engaging a driv e 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 vehi cle is stationary, it is necessary to
hold the car with the brake pedal in all the positions of the selector lever (except
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 gearbox). 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 inter-
rupted. 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 120.

The engine can only be started when the selector le ver is in position P or N
page 108. At temperatures below -10 °C the engine can only be started in the
selector lever position P .
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 position N is selected by accident while driving it is first necessary
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!
If you are stopping at a hill (downhill section), never try to hold the car
stationary with the gear engaged by mean s of the “accelerator”, this means by
letting the clutch slip. This can lead to ov erheating of the clutch. If there is a risk
of overheating of the clutch due to overlo ad, the clutch is opened automatically
and the vehicle rolls backward - risk of accident!
If yo u m us t s to p a t a sl ope , d e pre s s a nd ho ld t he b ra ke pe d a l , s o t ha t y ou c a n
prevent the vehicle from rolling back.Caution
The double clutch on the automatic gear box DSG is equipped with an overload
protection. If you make use of the uphill func tion on a vehicle which is stationary or
driving slowly uphill, it will result in an increase of thermal stress of the clutches.
An overheating of the clutches can be detect ed by the flashing of the selector level
indicator and the “jerk” of the clutches, finally the clutches are opened. The power
transmission from the engine to the front whee ls is interrupted and as a result of this
the vehicle can no longer be driven. If th e clutch opens automatically, depress the
brake pedal, wait a few seconds and only then continue driving.

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 hand-
brake 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 page 197, “Working in the engine compartment”.
Selector lever lockAutomatic 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 or der to move the selector lever out of this
position. The warning light
page 33 lights up in the instrument 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
seesaw out a stuck vehicle. The selector lever lo ck 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 swit ched off automatically into position N when the
car is travelling at a higher speed.
Shiftlock button
The Shiftlock button in the hand le of selector lever prevents certain selector lever posi-
tions 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 selector
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 a ccelerator pedal allows the kickdown function to be activated in
the desired driving program. This function has precedence over the driving
programme and serves for maximum accelerati on of the vehicle when exploiting the
maximum power potential of the engine wi thout taking into account the current
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 gearbox does not
shift up into the highest gear until the en gine has reached its maximum 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 programmeThe 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 po ssible will have a favourable effect on your fuel consump-
tion.
Adopting a sporty style of driving with rapid movements of the accelerator pedal
combined with sharp acceleration and freque nt changes in speed, exploiting the top
speed of the car or depressing the accele rator 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 driving is
a continuous process. Irrespective of this it is, however, possible to switch or shift down
into a dynamic shift programme by depressi ng the accelerator rapidly. The gearbox
shifts down into a lower gear matching the speed of the car and this allows you to

– If the rocker switches or are not pressed for some time, the manual shifting
switches off. You can also switch off the temporary switch over to manual shifting
by pressing the right rocker switch for more than 1 second.
Emergency programme
An emergency programme exists in th e event of a fault in the system.The gearbox operates in a corresponding emergency programme if there are func-
tional faults in the gearbox electronics. This is indicated by all of the segments in the
display lighting up or going out.
A functional fault can have the following effect:
The gearbox only shifts into certain gears.
The reverse gear R cannot be used.
The manual shift programme (Tiptronic) is switched off in the emergency mode.
If the gearbox has switch ed over to emergency mode, drive to the nearest
specialist garage in order to have the fault rectified.
Selector lever-emergency unlockingIn case of interruption of the power supply (e .g. flat vehicle battery, defective fuse) or
defect of the selector lever lock, the selector lever can no longer be shifted from the
position P in the normal way and the vehicle ca n no longer be moved. The selector
lever must be unlocked in case of emergency.
– Apply the handbrake firmly. – Open the storage compartment in front centre console* or the front ashtray.
– Carefully pull up the front left and right cover.
– Pull up rear cover.
– Use a finger to press the yellow pl
astic part in direction of arrow fig. 120 .
– Simultaneously press the shiftlock button in the handle of the selector lever and
shift the lever into the position N (if the selector lever is shifted again into the posi-
tion P, it is once again blocked).

Intelligent Technology
172
The Brake Assist is able to help you achieve a shorter braking distance in emergency
situations by rapidly producing the pressure required in the brake system. It fully
exploits the attributes of the ABS. After you release the brake pedal, the function of the
Brake Assist is automatically switched off and the brakes operate in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake Assist
function is also not available. Further information on the ESP page 167.
WARNING
The Brake Assist is also not able to overcome the physical limits of your
vehicle in terms of the braking distance required.
Adapt your speed to the conditions of the road surface and to the traffic situ-
ation.
The increased safety offered by the Brake Assist must not tempt you to take
a greater safety risk than otherwise.
Uphill Start Assist*The uphill start assist makes it easier to start off on steep hills. The system assists a start
off by holding the brake pressure produced by the brake pedal actuation for approx. 2
seconds after releasing the brake pedal. The driver can therefore move his foot from
the brake pedal to the accelerator pedal and start off on the slope, without having to
actuate the handbrake. The brake pressure drops gradually the more you operate the
accelerator pedal. If the vehicle does not start off within 2 seconds, it starts to roll back.
The uphill start assist is active as of a 5 % slope, if the driver door is closed. It is always
active on slopes when in forward or reverse start off. When driving downhill, it is
inactive.Electromechanical power steeringThe power steering enables you to steer the vehicle with le ss physical force.
With the electromechanical power steering , the steering assist is automatically
adapted to the speed and to the steering angle. It is still possible to fully steer the vehicle if the power steering fails or if the engine is
not running (vehicle being towed in). The only difference is that greater physical effort
is required.
If there is a fault in the power steering, the warning light
or lights up in the instru-
ment cluster page 30.
WARNING
Contact your specialist garage if the power steering is defective.Tyre pressure monitoring system*The tyre pressure monitoring system compares with the aid of the ABS sensors the
speed and also the rolling circumference of the individual wheels. If the rolling circum-
ference of a wheel is changed, the warning light
lights up in the instrument cluster
page 33 and an audible signal sounds. The rolling circumference of the tyre can
change if:
the tyre inflation pressure is too low,
the structure of the tyre is damaged,
the vehicle is loaded on one side,
the wheels of an axle are loaded heavily (e.g. when towing a trailer or when driving
uphill or downhill),
snow chains are mounted,
the temporary spare wheel is mounted,

Before starting off with a hitched trailer, also check the setting of the headlights. Alter
the setting as necessary with the ai

Detachable ball head
The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is
stowed together with separate fitting instru ctions in the spare wheel well in the luggage
compartment of the vehicle.
Further information on the towing device page 184.
Note
We recommend that you also have your vehicle inspected between service inter-
vals if you tow a trailer frequently.
The handbrake on the towing vehicle must be put on when coupling and decou-
pling the trailer.
Driving Tips
Particular caution is required when towing a trailer.– Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer is
laden. Maintain a particularly low speed if you cannot avoid driving with this combina-
tion.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for countries
in which higher speeds are allowed. The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when there
are unfavourable road, weather or wind cond
itions, particularly near accident black
spots.
You must always reduce your speed immediat ely as soon as you detect even just the
slightest swaying of the trailer. On no account attempt to stop the trailer from
“swaying” by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting from the
trailer wheels locking. Shift down gears in good time before negotiating a downhill
section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engi ne speed when the outside temperature is
very high page 16, “Coolant temperature gauge”.
If the needle of the coolant temperature gauge moves into the right-hand area or even
the red area of the scale, reduce your speed immediately. Stop and switch off the
engine if the warning light
in the instrument cluster begins flashing. Wait a few
minutes and check the level of coolant in the coolant expansion bottle page 201,
“Inspecting the coolant level”.
Please refer to the following guidelines page 31, “Coolant temperature/coolant
level ”.
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear and
increasing the engine speed is not possible since the fan speed is independent of the
engine speed. One should also not drop a gear for this reason when towing a trailer as
long as the engine can manage th e slope without any drop in speed.

Working in the engine compartment
Particular care is required when carrying out any work in the engine
compartment!There is a risk of injuries, scalding, acci dents and fire when working in the engine
compartment, e.g. inspecting and replenishing oil and other fluids. For this
reason, it is essential to comply with the warning instructions stated below and
with the general applicable rules of safe ty. The engine compartment of your car
is a hazardous area .
WARNING
Never open the bonnet if you see that steam or coolant is flowing out of the
engine compartment - risk of scalding! Wait long enough until the steam or
coolant has stopped escaping.
Switch off the engine and pull out the ignition key.
Apply the handbrake firmly.
If your vehicle is fitted with a manual gearbox, move the gearshift lever into
Neutral, or if it is fitted with automatic gearbox, move the selector lever into
position P.
Allow the engine to cool down.
Keep children clear of the engine compartment.
Never spill oil and other fluids over the hot engine. Such fluids (e.g. the anti-
freeze contained in the coolant) may ignite!
Avoid short circuits in the electrical system - particularly on the battery.
Never place your hand into the radiator fan as long as the engine is still
warm. The fan might su ddenly start running!
Never open the cap of the coolant expans ion bottle as long as the engine is
still warm. The cooling system is pressurized!
Cover over the cap of the coolant expansion reservoir with a large cloth
when opening it as protection for your face, hands and arms from hot steam or
hot coolant.
Do not let objects, such as e.g cleaning cloth or tools lie in the engine
compartment.
If you wish to work under the vehicl e, you must secure the vehicle from
rolling away and support it with suitable supporting blocks; the lifting jack* is
not sufficient for this - risk of injury!
In cases where it be necessary to carry out inspection work when the engine
is running there is an additional risk fr om rotating parts (e.g. the V-ribbed belt,
alternator, radiator fan) and from the high-voltage ignition system. Please
observe in addition the following:
Never touch the electrical cabl es of the ignition system.
Absolutely avoid any jewellery, loose it ems of clothing or long hair from
getting into the rotating parts of the engine - Hazard! Therefore remove any
jewellery beforehand, tie up your hair and wear tight fitting clothing.
Please also comply with the warnin g instructions stated below when
carrying out any essential work on the fu el system or on the electrical system:
Always separate the car battery from the electrical system.
Do not smoke.
Never carry out any work close to naked flames.
Always keep a working fire extinguisher at hand.Caution
When replenishing fluids in the engine, always ensure that the fluids are on no account
mixed up. This may result in major oper ating problems and also vehicle damage!

Spare wheel*The spare wheel lies in a well under the floor covering of the luggage compartment and
is fixed in place using special screws fig. 175 .
Before removing the spare wheel, you must take out the box with the vehicle tool kit
box page 216, fig. 174.
One should check the inflation pressure in the spare wheel (at best when generally
checking the tyre air pressures - see sign on the fuel filler flap page 208) to ensure
that the spare wheel is always ready to use.
Temporary spare wheel
A warning label displayed on the rim of the temporary spare wheel indicates that your
vehicle is equippe d with a temporary spare wheel.
Please observe the following notes when driving with a temporary spare wheel:
The warning label must not be covered after installing the wheel.
Do not drive faster than 80 km/h with this spare wheel and pay particular attention
while driving. Avoid accelerating at full throttle, sharp braking and fast cornering.
The inflation pressure for this spare wheel is identical to the inflation pressure of
the standard tyres. The temporary spare wheel R 18 must have an inflation pressure of
420 kPa (4.2 bar)!
Use this spare wheel only to reach the nearest specialist garage as it is not intended
for continuous use.
No other summer or winter tyres must be mounted on the rim of the spare wheel
R 18.
Changing a wheelPreliminary workThe following steps should be carried ou t before actually changing the wheel.
– If it is necessary to change a wheel, park the vehicle as far away as possible from
the traffic flow. The place you choose should be level.
–Have all the occupants get out. While changing a wheel, the occupants of the
vehicle should not stand on the ro ad (e.g. behind a crash barrier).
– Apply the handbrake firmly.
–Engage 1st gear or if your vehicle is fitted with an automatic gearbox, position the
selector lever into position P .
– If a trailer is coupled, uncouple it.
–Take the vehicle tool kit page 216 and the spare wheel* page 217 out of the
