“(START-STOP)” Fig. 105 Dash panel: START-STOP Sys-
tem button
The “START-STOP” system helps you to save fuel while at the same time reducing
harmful exhaust emissions and CO 2 emissions.
The function is automatically activated each time the ignition is switched on. In the start-stop mode, the engine automatically switches to the vehicle's idle
phase, e.g. when stopped at traffic lights.
Information regarding the current state of the
“START-STOP” system is indicated
in the display of the instrument cluster.
Automatic engine shut down (stop phase)
– Stop the vehicle (where necessary, apply the handbrake).
– Take the vehicle out of gear.
– Take your foot off the clutch.
Automatic engine restart (start phase).
– Push down on the clutch.
Switching the
“START-STOP” system on and off
You can switch the “START STOP” system on/off by pressing the button ⇒ fig. 105 .
When start-stop mode is deactivated, the warning light in the button lights up.
If the vehicle is in the stop phase when manually switching off the system, the en-
gine starts immediately.
The “START-STOP” system is very complex. Some of the procedures are hard to
check without servicing. The general conditions for the proper functioning of the
“START-STOP” system are listed in the following overview.
Conditions for the automatic engine shut down (stop phase) The gearshift lever is in Neutral.

START MANUALLY
Start the engine manually WARNING
● The brake servo unit and power steering only operate if the engine is run-
ning.
● Never let the vehicle roll with the engine switched off. CAUTION
If the “START-STOP” system is used at very high outside temperatures over a very
long period of time, the vehicle battery can be damaged. Note
● Changes to the outdoor temperature can have an effect on the internal tem-
perature of the vehicle battery even after several hours. If the vehicle remains
outdoors for a long time in minus temperatures or in direct sunlight, it can take
several hours until the internal temperature of the vehicle battery reaches a suita-
ble temperature for proper operation of the
“START STOP” system.
● In some instances it may be necessary to start the engine manually with the
ignition key (e.g. when the seat belt is not inserted or the driver's door is opened
for more than 30 seconds). Follow the messages in the instrument cluster display.
● If the Climatronic is running in automatic mode, under certain conditions, the
engine may not switch off automatically. 111

Automatic gearbox DSG
Automatic gearbox DSG
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. 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 115.
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 113, and then release
the Shiftlock button.
– 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. 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 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!
● If you are stopping at a hill (downhill section), never try to hold the car sta-
tionary with the gear engaged by means of the
“accelerator”, this means by
letting the clutch slip. This can lead to overheating of the clutch. If there is a
risk of overheating of the clutch due to overload, the clutch is opened auto-
matically and the vehicle rolls backward - risk of accident!
● If you must stop at a slope, depress and hold the brake pedal, so that you
can prevent the vehicle from rolling back. £112
Automatic gearbox DSG

CAUTION
● The double clutch on the automatic gearbox DSG is equipped with an overload
protection. If you make use of the uphill function on a vehicle which is stationary
or driving slowly uphill, it will result in an increase of thermal stress of the clutch-
es.
● In the event that they overheat, the warning light and a warning text ap-
pears in the information display ⇒ page 30. In such a case bring the vehicle to a
stop, switch off the engine and wait until the warning light and the warning go
out - risk of gearbox damage! You can continue the trip as soon as the warning
light and the warning go out.
Selector lever positions Fig. 106 Selector lever/information display: Selector lever positions
The current selector lever position is indicated in the information display of the in-
strument cluster
⇒ fig. 106 - right. In the positions D and S the gear you have al-
ready engaged 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.
If the battery is used, the selector lever cannot be moved out of the position P.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 or R, 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 into position D from N
when the vehicle is travelling at less than 5
km/hour or is stationary ⇒ .
Under certain circumstances (e.g. when driving in mountainous regions or when
towing a trailer) it may be beneficial to select the manual shift programme
⇒ page 115 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 Shiftlock on the selector lever grip must be pressed when moving the selec-
tor lever out of the position D into the position S. £ 113

WARNING
● The front seats and the head restraints must always be adjusted to match
the body size of the seat occupant as well as the seat belts must always be
correctly fastened in order to provide an optimal protection for you and your
occupants.
● The driver must maintain a distance of at least 25 cm between the steering
wheel, and a distance of at least 10 cm between the legs and the gear lever at
the height of the knee airbag ⇒ fig. 115 - left. Not maintaining this minimum
distance will mean that the airbag system will not be able to properly protect
you - hazard!
● When driving, hold the steering wheel with both hands firmly on the outer
edge in the 9 o'clock and 3 o'clock position. Never hold the steering wheel
firmly in the 12 o'clock position or in another way (e.g. in the middle of the
steering wheel or at the inner steering wheel edge). In such cases, injuries to
the arms, the hands and the head can occur when the driver airbag is de-
ployed.
● The seat backrests must not be angled too far back when driving other-
wise this will affect proper operation of the seat belts and of the airbag sys-
tem - risk of injury!
● Ensure that there are no objects in the footwell as any objects may get be-
hind the pedals during a driving or braking manoeuvre. You would then no
longer be able to operate the clutch, to brake or accelerate.
Correct seated position for the front passenger The front passenger must maintain a distance of at least 25 cm
from the dash panel so that the airbag offers him the greatest pos-
sible safety it is deployed.
For the safety of the front passenger and to reduce the risk of injury in the event
of an accident, we recommend the following setting.
● Adjust the front passenger seat as far as possible to the rear.
● Adjust the head restraint so that the top edge of the head restraint is at the
same level as the upper part of your head ⇒
fig. 115 - right.
● Fasten the seat belt correctly ⇒
page 134, How are seat belts correctly fas-
tened?.
In exceptional cases the front passenger airbag can be deactivated ⇒ page 144,
Deactivating an airbag. Manual front passenger adjustment
⇒
page 61.
Electrical front passenger seat adjustment ⇒ page 63, Adjusting front seats elec-
trically. WARNING
● The front seats and the head restraints must always be adjusted to match
the body size of the seat occupant as well as the seat belts must always be
correctly fastened in order to provide an optimal protection for you and your
occupants.
● The front passenger must maintain a distance of at least 25 cm to the dash
panel. Not maintaining this minimum distance will mean that the airbag sys-
tem will not be able to properly protect you - hazard!
● Always keep your feet in the footwell when the car is being driven - never
place your feet on the instrument panel, out of the window or on the surfaces
of the seats. You will be exposed to increased risk of injury if it becomes nec-
essary to apply the brake or in the event of an accident. If an airbag is de-
ployed, you may suffer fatal injuries when adopting an incorrect seated posi-
tion!
● The seat backrests must not be angled too far back when driving other-
wise this will affect proper operation of the seat belts and of the airbag sys-
tem - risk of injury!
Correct seated position for the occupants on the rear seats Occupants on the rear seats must sit upright, keep the feet in the
footwell and must have their seat belts correctly fastened.
To reduce the risk of injury in the event of a sudden braking manoeuvre or an acci-
dent, the occupants on the rear seats must observe the following:
● Adjust the head restraints so that the top edge of the head restraints is at the
same level as the upper part of your head ⇒ fig. 115 - on the right.
● Fasten the seat belt correctly ⇒ page 134, How are seat belts correctly fas-
tened?.
● If you are transporting ⇒ page 146
, Transporting children safely children in the
vehicle, please use a suitable child restraint system. £130
Passive Safety

There also may be a certain delay before the full braking efficiency is available
when driving on roads which have been treated with road salt if you have not
used the brakes for some considerable time beforehand. The layer of salt on the
brake discs and brake pads must first be rubbed off when you apply the brakes.
Corrosion
Corrosion on the brake discs and dirt on the bake pads occur if the vehicle has
been parked for a long period and if you do not make much use of the braking sys-
tem.
We recommend cleaning the brake discs by firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-
sion is present ⇒ .
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 29, 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! 156
Intelligent technology

CAUTION
● Pay attention to the ground clearance of the vehicle! The vehicle can be se-
verely damaged and become disabled once it touches the ground.
● Never drive off-road with an almost empty fuel tank. The fuel supply to the en-
gine can be interrupted and therefore the catalytic converter can be severely
damaged.
● Do not leave your foot on the clutch pedal or let the clutch slip when driving
off-road. Overwise you may unintentionally depress the clutch pedal on uneven
ground leading to a loss of control over the vehicle. In addition, the force for con-
necting the engine and the gearbox is lost. Moreover, driving while letting the
clutch slip causes a fast wear of the clutch linings. Note
The fuel consumption is higher when driving off-road than when driving on con-
ventional roads, especially through difficult terrain. When you prepare for your
journey, be aware of an increase in fuel consumption; the nearest filling station
may be far away.
Shifting gears correctly The gear you must shift into depends on the terrain. Choosing the correct gear
contributes to safe driving. In particular if you do not have much experience driv-
ing off-road, it is always better, before negotiating a difficult stretch of the road,
to pause and reflect on which gear to engage. Your experience will tell you which
gear is the best for certain sections of the terrain.
Basically:
● When the gear or the driving stage has been properly selected, it is unneces-
sary to slow down the vehicle on a downhill section using the footbrake as in
most cases the engine braking power is sufficient.
● Depress the accelerator only as much as is necessary. A too great acceleration
may lead to the wheels spinning and thus results in the loss over the control of
the vehicle. Manual gearbox
● If you are driving through difficult terrain, on no account use the clutch or
change the gear. When the clutch is depressed, the vehicle may come to a stand-
still because of the increased grip of all the tyres of the vehicle (e.g. in the mud, in
deep sand or on a slope). Once the vehicle has come to a standstill, it may be diffi-
cult or even impossible to start off under these conditions.
● When negotiating a steep downhill section or a steep uphill section, always
shift into the 1st or 2nd gear.
● On a soft or slippery ground, you must drive at the appropriate speed and you
must select the highest possible gear for this.
Automatic gearbox
● Select the selector lever position D for normal flat stretches of terrain
⇒ page 113.
● While in the Tiptronic mode, select the selector lever position 3 or
2 if you
are driving through mud, sand, water or hilly sections of terrain ⇒ page 115.
● When negotiating a steep downhill section or a steep uphill section, select the
selector lever position 1 while in the Tiptronic mode.
● On a soft or slippery ground, you must drive at the appropriate speed and you
must select the highest possible driving stage.
Driving over rough and smooth Fig. 148 Observe the ground clearance
– Switch on the Off-road mode ⇒ page 160 .
– Drive at walking speed over rocky passages.
– If it is not possible to drive around a stone, gently drive onto the stone with
one of the front wheels and then drive over it slowly. £172
Driving and the environment

WARNING
Observe the important guidelines ⇒ page 168. CAUTION
● On no account drive over large objects (such as pieces of rock or tree stumps),
neither in the middle nor on one side. When driving over objects which are larger
than the ground clearance, the chassis and its components can get damaged. Your
vehicle could break down far away from any assistance.
● Even objects that are smaller than the existing ground clearance can come in-
to contact with the underbody of the vehicle and can lead to damage or failure of
the vehicle. This applies especially when there is a hollow or soft ground in front
or behind the object or if you drive too fast over the object and thus the vehicle is
deflected. For the sake of the environment
Leaking engine oil and brake fluid pollute the environment and contaminate the
bodies of water. The disposal e.g. of engine oil soaked soil can be costly.
Crossing bodies of water Particular attention is required when driving through bodies of water
⇒
page 167.
Driving through snow-covered terrain –
Before you drive through snow-covered terrain, mount snow chains on the
front wheels or on the rear wheels ⇒ page 205, Snow chains in order to ach-
ieve the best possible traction.
– Switch on the Off-road mode ⇒ page 160
.
Even harmless looking sections of terrain can be dangerous. This applies in partic-
ular for sections where no ruts or other tracks are visible. WARNING
● Driving through snow-covered terrain poses special dangers. Never choose
a dangerous route and never take a risk which could jeopardize your safety
and that of your passengers. If you cannot go on or if you doubt the safety of
the route, turn back and choose another way.
● Potholes, troughs, trenches, precipices, sheets of ice or other obstructions
are often completely or partially obscured by snow.
● The hidden dangers of snow can cause an accident, serious injuries or your
vehicle to break down under extreme weather conditions.
Driving over steep terrain Driving uphill and downhill
–
Stop the vehicle before driving uphill or downhill, exit the vehicle and explore
the situation.
– Walk a stretch and check the firmness of the soil and look for obstructions or
other hidden dangers.
– Check how the route continues beyond the slope.
– Switch on the Off-road mode ⇒ page 160
.
– Drive slowly and steadily straight uphill or downhill.
– Do not stop the vehicle on a hillside or attempt to turn around.
– You must prevent the engine from cutting out.
Driving uphill
– Check before driving over a hilltop, how it continues on the other side. If you
drive up a steep hill, the vehicle faces the sky and you cannot see what is di-
rectly in front of the vehicle.
– Switch on the Off-road mode
⇒ page 160
.
– Do not shift gears or release the clutch during the climbing phase.
– Depress the accelerator only as much as is necessary in order to handle the
slope.
If you can go no further on a slope
– Never attempt to make a turn with the vehicle on a hillside.
– If the engine cuts out, press the foot brake and restart the engine. £ 173
