aged or made unsuitable for use by the air coming from the air vents. Air recirculation
Basic points
Air recirculation:
Manual air recirculation (heating and fresh air system, manual
air conditioning).
Air recirculation mode prevents the ambient air from entering the interior.
When the outside temperature is very high, selecting manual air recircula-
tion mode for a short period refreshes the vehicle interior more quickly.
For safety reasons, air recirculation mode is switched off when the button
 is pressed or the air distributor turned to
.
Switching on and switching off manual air recirculation with air conditioner
(manual) or with the heating and fresh air systems 
Activate: press the button  until the warning lamp lights up.
Deactivate: press the button  until all warning lamps switch off.
Switching on and off manual air recirculation with Climatronic 
Activate: press the * button until the warning lamp lights up.
Deactivate: press the * button until all warning lamps switch off.
Functioning mode of manual air recirculation (air conditioning menu)
With the automatic air recirculation mode activated, the entry of fresh air in-
to the cabin interior is enabled. If the system detects a high concentration
of hazardous substances in the ambient air, air recirculation mode is
switched on automatically. When the level of impurities drops to within a
normal range, recirculation mode is switched off.
The system is unable to detect unpleasant smells.
Air recirculation mode is not automatically switched on in the following ca-
ses of outside temperatures and conditions: 

Driving
Always apply the handbrake as far as it will go in order to prevent yourself
from driving with the handbrake applied by mistake ⇒ 
.
The handbrake warning lamp  lights up when the handbrake is applied
and the ignition switched on. The warning lamp turns off when the hand-
brake is released.
If you drive faster than 6 km/h (4 mph) with the handbrake on, the following
message* will appear on the instrument panel display: HANDBRAKE ON. You
will also hear an audible warning.
WARNING
● Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied
to the rear wheels. Risk of accident!
● If the handbrake is only partially released, this will cause the rear
brakes to overheat, which can impair the function of the brake system
and could lead to an accident. This also causes premature wear on the
rear brake pads.
CAUTION
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected. 
Parking
The handbrake should always be firmly applied when the
vehicle is parked.
Always note the following points when parking the vehicle:
– Use the brake pedal to stop the vehicle. –
Apply the handbrake.
– Select first gear.
– Switch the engine off and remove the key from the ignition. Turn
the steering wheel slightly to engage the steering lock.
– Always take you keys with you when you leave the vehicle ⇒ 
.
Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle rolls against the kerb if it started
to roll.
● If the vehicle is parked facing downhill, turn the front wheels so that
they point towards the kerb .
● If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .
● Secure the vehicle as normal by applying the handbrake firmly and se-
lecting first gear.
WARNING
● Take measures to reduce the risk of injury when you leave your vehi-
cle unattended.
● Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.
● Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to vehicle occupants.
● Never leave children alone in the vehicle. They could set the vehicle
in motion, for example, by releasing the handbrake or the gearbox lever.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.

exceeded when winter tyres are fitted etc.
Note
● Please bear in mind that, even with the speed warning function, it is still
important to keep an eye on the vehicle speed with the speedometer and to
observe the legal speed limits.
● The speed limit warning function in the version for several countries
warns you at a speed of 120 km/h (80 mph). This is a factory-set speed lim-
it. 
Setting speed limit warning
You can use the radio or the Easy Connect* to set, alter or
cancel the speed limit warning.

– Select: SETUP
button > control button 
Driver assistant > Speed
warning.
Vehicles with Easy Connect
– Select: Systems control button or Vehicle systems > Driver assis-
tant > Speed warning.
The warning limit can be set from 30 to 240 km/h (20 to 150 mph). The ad-
justment is done in 10 km/h (mph) intervals. Start-Stop system*
Description and operation
The Start-Stop system helps save fuel and reduce CO 2 emissions.
In Start-Stop mode, the engine will automatically switch off when the vehi-
cle stops, when stopping at traffic lights for example. The ignition remains
switched on during the stopping phase. The engine automatically switches
back on when required.
As soon as the ignition is switched on, the Start-Stop function is automati-
cally activated.
Basic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fastened.
● The bonnet must be closed.
● The vehicle must have travelled at more than 4 km/h since the last stop.
● The vehicle cannot be towing a trailer.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered under
warranty. More force may also be needed to turn the steering wheel or to
brake. As you cannot steer and brake in the normal manner, there is a
greater risk of accidents and serious injury.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could lock making it impossible to steer the vehi-
cle. 

Driving
CAUTION
When travelling at high speeds or at high engine speeds, selecting a gear
that is too low can cause considerable damage to the clutch and the gear-
box. This can also occur if the clutch pedal is pressed and held and it does
not engage.
CAUTION
To prevent damage and avoid premature wear, please observe the follow-
ing:
● Do not rest your hand on the gear lever while driving. The pressure ap-
plied by your hand is transmitted to the gearbox selector forks.
● Always ensure that the vehicle is completely stopped before engaging
the reverse gear.
● Always press the clutch to the floor when changing gears.
● Never hold the vehicle “on the clutch” on hills with the engine on. 
Automatic gearbox/DSG automatic gearbox* Introduction
Your vehicle is equipped with an electronically controlled manual gearbox.
Torque between the engine and the gearbox is transmitted via two inde-
pendent clutches. They replace the torque converter found on conventional
automatic gearboxes and allow for smooth, uninterrupted acceleration of
the vehicle.
The tiptronic system allows the driver to change gears manually if desired
⇒  page 178, Changing gears in tiptronic mode*. Selector lever positions
The selector lever position engaged is highlighted on the display in the in-
strument cluster. With the selector lever in the manual gearbox positions G,
D, E and S, the engaged gear is also indicated on the display.
P – Parking lock
When the selector lever is in this position, the driven wheels are locked me-
chanically. The parking lock must be engaged only when the vehicle is
sta-
tionary ⇒ 
.
The interlock button (the button on the selector lever handle) must be
pressed in and simultaneously the brake pedal must be depressed before
moving the selector lever either in or out of position P.
R – Reverse gear
Reverse gear must be engaged only when the vehicle is stationary and the
engine is idling ⇒ 
.
To move the selector lever to position R, the interlock button must be press-
ed in and at the same time the brake pedal must be depressed. The reverse
lights come on when the selector lever is in the R position with the ignition
on.
N – Neutral (idling)
With the selector lever in this position, the gear is in neutral.
D/S – Permanent drive (forward) position
The selector lever in the D/S position enables the gears to be controlled in
normal mode (D) or Sport (S). To select Sport mode (S), move the selector
lever backwards. Moving the lever again will select normal mode (D). The
selected driving mode is shown on the instrument panel display.
In normal mode (D), the gearbox automatically selects the best gear ratio.
This depends on the engine load, the road speed and the dynamic gear
control programme (DCP). 
Safety FirstOperating instructionsPractical TipsTechnical specifications

176Driving
Note
● If the selector lever lock does not engage, there is a fault. The transmis-
sion is interrupted to prevent the vehicle from accidentally moving. Follow
the procedure below in order for the selector lever lock to engage again:
–With a 6-speed gearbox: press the brake pedal and release it again.
– With a 7-speed gearbox: press the brake pedal. Move the selector lev-
er to position P or N and subsequently engage a gear.
● Despite a gear being engaged, the vehicle does not move forwards or
back. Proceed to the next mode:
–When the vehicle does not move in the required direction, the system
may not have the gear range correctly engaged. Press the brake pedal
and engage the gear range again.
– If the vehicle still does not move in the required direction, there is a
system malfunction. Seek specialist assistance and have the system
checked. 
Driving tips
The gearbox changes gear ratios automatically as the vehi-
cle moves.
The engine can only start with the selector lever in the position P or
N. At low temperatures, below -10 °C (50 °F), the engine can only
start with the selector lever in the position P.
Starting the vehicle
– Press and hold the brake pedal.
– Press and hold the interlock button (the button in the selector
lever handle), move the selector lever to the desired position,
for instance D ⇒  page 173, and release the interlock button. –
Wait for the gearbox to engage the gear (a slight movement can
be felt).
– Release the brake and press the accelerator ⇒ 
.
Stopping briefly
– Apply the foot brake to hold the vehicle when stationary (for in-
stance at traffic lights). Do not press the accelerator.
Stopping/Parking
If the driver door is opened and the selector lever is not in position
P, the vehicle could move. Driver message:  Gear change: selector
lever in drive position! will be displayed. Additionally, a buzzer will sound.
– Press and hold the brake pedal ⇒ 
.
– Apply the handbrake.
– Move the selector lever to position P.
Holding the car on a hill
– Always apply the brake pedal firmly to prevent the vehicle from
“moving backwards; if necessary, apply the handbrake” ⇒ 
.
Do not try to stop the vehicle “rolling back” by increasing the
engine speed when a gear is engaged (pressing the accelera-
tor) ⇒ 
.
Moving off uphill in vehicles without Hill start assistant*
– Apply the handbrake.
– Once you have engaged a gear press the accelerator carefully
and disengage the handbrake. 

177
Driving
Moving off uphill in vehicles with Hill start assistant*
– Once you have engaged a gear, release the footbrake and press
the accelerator ⇒ page 168, Hill driving assistant*.
Driving down hills: In some situations (on mountain roads or when towing a
trailer or caravan) it can be advantageous to switch temporarily to the man-
ual gearbox programme so that the gear ratios can be selected manually to
suit the driving conditions ⇒ 
.
On level ground it is sufficient to move the selector lever to position P. On
slopes, first engage the parking brake and then put the selection lever into
the P position. This avoids overloading the locking mechanism and it will be
easier to move the selector lever from position P.
WARNING
● As a driver you should never leave your vehicle if the engine is run-
ning and a gear is engaged. If you have to leave your vehicle while the
engine is running, you must apply the handbrake and engage the parking
lock P.
● If the engine is running and a gear is engaged (D/S or R) or the vehi-
cle is in tiptronic mode, you will need to hold the car with the footbrake.
Otherwise, the car will creep forwards as the power transmission is not
fully interrupted even when the engine is idling.
● Take care not to accidentally press the accelerator pedal when the ve-
hicle is stopped. The vehicle could otherwise start moving immediately
(in some cases even if the parking brake is engaged) resulting in the risk
of an accident.
● While you are selecting a gear and the vehicle is stopped with the en-
gine running, do not accelerate. Failure to do so could result in an acci-
dent.
● Never move the selector lever to R or P when driving: this could result
in an accident!
WARNING (Continued)
● Before you drive down a steep gradient, reduce your speed and use
tiptronic to select a low gear.
● Never allow the brake to rub and do not use the brake pedal too often
or for long periods. Constant braking causes overheating in the brakes.
This could significantly reduce braking power, increase braking distance
or even result in the total failure of the brake system.
● To avoid rolling back on gradients always hold the vehicle with the
footbrake or handbrake if you have to stop.
CAUTION
● If you stop the vehicle on a gradient, do not attempt to stop it from roll-
ing by depressing the accelerator when a gear has been selected. This
could cause overheating and damage the automatic gearbox. Apply the
handbrake firmly or press the brake pedal in order to prevent the vehicle
from rolling back.
● If you allow the car to roll with the selector lever in position N with the
engine switched off, the automatic gearbox will be damaged as it will not be
lubricated.
● In certain driving situations or traffic conditions, such as frequently
starting, prolonged “creeping” of the vehicle or traffic jams with continuous
stoppages, the gearbox could overheat causing damage! If the warning
lamp  lights up, stop the vehicle as soon as possible and wait for the
gearbox to cool ⇒ page 181.

prox. 3200 rpm (petrol engine) or approx. 2000 rpm (diesel en-
gine).
– Take your left foot off the brake pedal.
WARNING
● Always adapt your driving style to the traffic conditions.
● Only use the “Launch control programme” when road and traffic con-
ditions permit, and make sure the way in which you drive and accelerate
the vehicle does not inconvenience or endanger other road users.
WARNING (Continued)
● Make sure that the ESC remains switched on. Please note that when
the ASR and ESC are deactivated, the wheels may start to spin, causing
the vehicle to lose grip. Risk of accident!
● After putting the vehicle into gear, the “sport” mode of the ESC
should be deactivated again by briefly pressing the 
OFF
button.
Note
● After using the “Launch control programme”, the gearbox temperature
may have increased considerably. In this case, the programme could be dis-
abled for several minutes. The programme can be used again after the cool-
ing phase.
● Accelerating with the “Launch control programme” places a heavy load
on all parts of the vehicle. This can result in increased wear and tear. 
Inertia mode
The inertia mode enables the kinetic energy of the vehicle to be
harnessed enabling certain stretches to be driven without using
the accelerator. This enables fuel to be saved. Use the inertia mode
to “let the vehicle roll” before, for example, arriving in a town.
Switching on inertia mode
Important: selector lever must be in position D, gradients below
12 %. 
