WARNING
In the event that an automatic anti-dazzle rear vision mirror breaks, an
electrolyte fluid may leak. This could cause irritation to the skin, eyes
and respiratory organs. If you come into contact with this liquid, it must
be rinsed with large quantities of water. If necessary, get medial help.
CAUTION
In the event that an automatic anti-dazzle rear vision mirror breaks, an elec-
trolyte fluid may leak. This liquid attacks plastic surfaces. Clean the liquid
with a wet sponge as soon as possible.
Note
● If the light incident in the interior rear vision mirror is obstructed (e.g.
with the sun blind*), the anti-dazzle rear vision mirror with automatic set-
ting will not operate perfectly.
● When the interior lights are on or reverse gear engaged, the rear vision
mirrors do not darken with automatic adjustment for anti-dazzle position. 

Air conditioning
There are other additional, non-adjustable air vents in the dash panel 2
, in
the footwell and in the rear area of the interior.
Note
Never place food, medicines or other heat-sensitive objects close to the air
vents. Food, medicine and other heat or cold sensitive objects may be dam-
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:
● The cooling system is switched on (the * button lamp is on) and the am-
bient temperature is below +3 ° C (+38 ° F).
● The cooling system and the windscreen wipers are switched off and the
outside temperature is below +10 °C (+50 °F).
● The cooling system is switched on, the outside temperature is below
+15 °C (+59 °F) and the windscreen wipers are switched on.
Activation/deactivation of automatic air recirculation is done in the air con-
ditioner menu, under Configuration.
WARNING
Stuffy or used air will increase fatigue and reduce driver concentration
possibly resulting in a serious accident.
● Never use recirculation mode for long periods as it does not refresh
the air inside the vehicle.
● If the cooling system is switched off and air recirculation mode
switched on, the windows can mist over very quickly, considerably limit-
ing visibility.
● Switch air recirculation mode off when it is not required. 

Handbrake Using the handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.
Fig. 87 Handbrake be-
tween the front seats
Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒ Fig. 87.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ Fig. 87 and guide the handbrake lever
down fully ⇒ 
. 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. 

Speed warning function
Introduction
The speed warning function can help prevent you exceeding
a particular pre-set maximum speed. The speed warning function will warn the driver if a pre-set maximum speed
is exceeded. The system gives a warning buzzer signal if the set speed is
exceeded by about 3 km/h (2 mph). The warning lamp  and the driver
message Speed limit exceeded! will be displayed simultaneously on the in-
strument panel display. The warning lamp  switches off when reducing
speed below the stored maximum limit.
You are recommended to store this speed limit warning if you always wish
to be reminded of a particular speed limit. This could be when driving in
countries with general speed limits, or if a particular speed should not be
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.
Vehicles with radio
– 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. 

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 159, 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).
Sport mode (S) must 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 noticeable.
The brake pedal must be pressed when moving the selector lever from D/S
to N if the vehicle is stationary or at speeds below 5 km/h (3 mph) ⇒ 
.
Under certain circumstances (e.g. when driving in mountains) it can be ad-
vantageous to switch temporarily to tiptronic mode ⇒ page 159, in order to
manually select gear ratios to suit the driving conditions.
WARNING
● 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.
● Never move the selector lever to R or P when driving. Failure to do so
could result in an accident. 

158Driving
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 automatic 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 162.
● In certain driving situations or traffic conditions, such as frequently
starting, prolonged creeping of the vehicle, or traffic jams with continuous
stoppages, the automatic 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 162. 
Downhill speed control*
The downhill speed control function helps the driver when
driving down steep gradients.
Downhill speed control is activated when the selector lever is in D/S and
the driver applies the foot brake. The automatic gearbox automatically en-
gages a lower gear that is suitable for the slope. The downhill speed control
function attempts to maintain the speed at which the vehicle was travelling
when the foot brake was applied (subject to the laws of physics and techni-
cal drive limitations). It may be necessary to adjust the speed again using
the foot brake in certain situations. Given that the downhill speed control
can only change down to 3rd gear, on very steep descents the tiptronic mode may be required. In this case, manually reduce the tiptronic to 2nd or
1st gear to use the engine brake and reduce the charge on the brakes.
Downhill speed control is deactivated as soon as the road levels out again
or you press the accelerator pedal.
On vehicles with cruise control system* ⇒ 
page 164, downhill speed con-
trol is activated when you set a cruising speed.
WARNING
The downhill speed control cannot defy the laws of physics. Therefore,
speed cannot be maintained constant in all situations. Always be pre-
pared to use the brakes!


160Driving
Kick-down feature
The kick-down feature allows maximum acceleration to be
reached.
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will shift down to a lower gear, depending
on road speed and engine speed. The upshift to the next higher gear is de-
layed until the engine reaches maximum rpm.
WARNING
Please note that if the road surface is slippery or wet, the kick-down fea-
ture could cause the driving wheels to spin, which could result in skid-
ding.

Launch Control Programme 1)
The Launch control programme enables maximum accelera-
tion.
Important: the engine must have reached operating temperature
and the steering wheel must not be turned.
The engine speed for Launch control is different on petrol and die-
sel engines. Before you can use the Launch control, you must first switch off the traction control system (ASR), either using the Easy
Connect system
⇒ page 79, or with the switch 
