180To move the selector lever to position R, press in the interlock button and at
the same time press the brake pedal. Depending on the model, one or two
reverse lights will come on in selector lever position R (when ignition is
switched on).
N - Neutral (idling)
In this position the gearbox is in neutral ⇒.
D - Drive (forward)
In this position, the gearbox selects the optimal transmission ratio
depending on the engine load, speed and the dynamic gear regulation
programme (DRP).
Press the brake pedal when moving the selector lever from N to D if the
vehicle is stationary or at speeds below 5 km/h ⇒.
Under certain circumstances (e.g. when driving in mountains or towing a
trailer or caravan) it can be advantageous to switch temporarily to tiptronic
mode ⇒page 183, so that the gear ratios can be selected manually to suit
the driving conditions.
S - Sport position
To drive in sports mode, select the position S. The engine power reserve is
used to its maximum. When accelerating the gear shifts will be noticeable.
Press the brake pedal when moving the selector lever from N to S if the
vehicle is stationary or at speeds below 5 km/h ⇒.
WARNING
•Never move the selector lever to R or P when driving. Failure to do so
could result in an accident.•In selector position D or S the vehicle must always be held with the foot
brake when the engine is running. This is because an automatic gearbox
still transmits power even at idling speed, and the vehicle tends to “creep”.
The throttle must on no account be opened inadvertently (for instance by hand from the engine compartment) when a gear is engaged with the
vehicle stationary. The vehicle could otherwise start moving immediately
(in some cases even if the parking brake is engaged) and possibly cause an
accident.
•To avoid accidents, apply the parking brake and put the selector lever
in position P before opening the bonnet and working on the vehicle with
the engine running. Please observe the important safety warnings
⇒ page 224, “Work in the engine compartment”.Note
•Applies to vehicles with tiptronic gearbox:•If the lever is moved accidentally to N when driving, release the acceler-
ator and let the engine speed drop to idling before selecting D or S again.•For the sake of fuel economy (and the environment), the gearbox ratios on
some models are designed so that maximum speed is only obtained when
the gear lever is in position S.WARNING (continued)

Selector lever lock
The selector lever lock prevents gears from being engaged
inadvertently, so that the vehicle is not set in motion uninten-
tionally.The selector lever lock is released as follows:
– Switch the ignition on.
–Press the brake pedal and at the same time press in the interlock
button.Automatic selector lever lock
With the ignition turned on, the selector lever is locked in the positions P and
N. To remove it from these positions, press on the brake. The following
message appears in the instrument panel as a reminder for the driver when
the selector lever is in position P or N:
WHEN STATIONARY APPLY FOOTBRAKE WHILE SELECTING GEAR The selector lever lock only works if the vehicle is stationary or driving at
speeds up to 5 km/h. At higher speeds the selector lever lock in the N posi-
tion is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved quickly
through position N (e.g. when shifting from R to D). This makes it possible, for
instance, to “rock” the vehicle backwards and forwards if it is stuck in snow
or mud. The selector lever lock engages automatically if the brake pedal is not
depressed and the lever is in position N for more than about a second.
Interlock button
The interlock button on the selector lever handle prevents the driver from
inadvertently engaging particular gears. Press the button in to disengage the
selector lever lock. The selector lever
positions in which the interlock button
has to be pressed are shown in the illustration, highlighted in colour
⇒ fig. 145 .
Safety interlock for ignition key
Once the ignition has been turned off, the key may be removed only if the gear
selector is in position P. While the key is not in the ignition, the selector lever
is locked in position P.
Kick-down feature
The kickdown feature is designed to give maximum accelera-
tion.Vehicles with multitronic
® gearbox
When the accelerator pedal is pressed right down past the point of resistance
at full throttle, the gearbox will select a lower gear ratio, depending on road
speed and engine speed. While you keep the accelerator depressed the
engine speed is automatically controlled to give your vehicle maximum accel-
eration.

184Back-up programme
A back-up system is in place if a fault should occur in the
control system.The automatic gearbox switches to the back-up programme if a fault should
occur in the control system. This is indicated by a gear pinion symbol which
lights up on the instrument panel display.
It is still possible to move the selector lever to all positions. The manual shift
programme (tiptronic) is not available when the back-up programme is
active.
Vehicles with tiptronic gearbox: when the selector lever is in position D or S
or in the manual shift programme, the gearbox will remain in 3rd gear if 1st,
2nd or 3rd gears were engaged when the fault occurred. The gearbox will
remain in 5th gear if 4th, 5th or 6th gears were engaged. The gearbox will
then engage 3rd gear when you drive away from a standstill or after the
engine is restarted.
It will still be possible to use reverse gear in the normal way. However, the
electronic lock for reverse gear will be switched off.
Caution
Should the gearbox ever switch into the back-up programme, you should take
the vehicle to a technical service or qualified workshop as soon as possible.
Steering wheel with paddle levers
The paddle levers on the steering wheel enable the driver to
manually select pre-programmed ratios or gears.– Briefly pull the left-hand paddle lever to change down to a
lower gear.
– Briefly pull the right-hand paddle lever to change up to a higher gear.The paddle levers are activated when the selector lever is in position D or S,
or the position for the manual shift programme (tiptronic).
The manual shift programme can, of course, still be operated using the
selector lever in the centre console.

186If required, the ESP can also be enabled and disabled manually by briefly
pressing the button ⇒ page 185, fig. 149. The ESP warning lamp lights
up when the system is switched off, see ⇒page 68.
In general, the ESP should be left switched on at all times. In particular
circumstances where a certain amount of wheel slip is desirable, it may be
advisable to switch off the ESP. Examples:•when driving with snow chains•when driving in deep snow or on loose surfaces•when rocking the vehicle backwards and forwards to free it.
The ESP should be switched on again afterwards as soon as possible.WARNING
The ESP is not able to overcome the physical limits of adhesion. Even with
ESP, you should always adjust your speed to suit the conditions. Please

extra safety features tempt you into taking any risks when driving. Failure
to do so could result in an accident.Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under braking.The anti-lock brake system (ABS) is an important part of the vehicle’s active
safety system. However, the ABS will not necessarily guarantee shorter stop-
ping distances in all conditions. For instance, on loose gravel or fresh snow
on top of an icy surface (conditions which anyway require extreme care and
reduced speed), the stopping distance with ABS may even be slightly longer. How the ABS works
The system runs an automatic self-check when the vehicle reaches a road
speed of about 6 km/h. This may be accompanied by a noise from the ABS
pump.
When one of the wheels is turning very slowly in relation to the road speed
and is close to locking up, the system will reduce the brake pressure on that
wheel. The driver is made aware of this adjustment process by a vibration of
the brake pedal
and an audible noise. This is a deliberate warning to the
driver that one or more of the wheels is tending to lock up and the ABS control
function has intervened. In this situation it is important to keep the brake
pedal fully depressed so the ABS can regulate the brake application, but do
not “pump” the brake pedal.
WARNING
The grip provided by ABS is still subjec t to the physical limits of adhesion.
Always bear this in mind, especially on wet or slippery roads. If you notice
that the ABS is working (to counteract locked wheels under braking), you
should reduce speed immediately to suit the road and traffic conditions. Do
not let the extra safety features tempt you into taking any risks when
driving. Failure to do so could result in an accident.
Note
If a malfunction should occur in the ABS, this is indicated by a warning lamp
⇒ page 67.

NoteIf the ABS warning lamp lights up, this can also mean there is a fault in the
EDL. Please take the vehicle to a qualified workshop as soon as possible.Traction control system (TCS)
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating.General notes
The traction control system (TCS) is one of the functions incorporated in the
Electronic Stability Programme (ESP).
The traction control system (TCS) helps the vehicle to start moving, accelerate
or climb a gradient in slippery conditions where this may otherwise be diffi-
cult or even impossible.
How it works
The TCS acts automatically, without the driver’s intervention. With the aid of
the ABS sensors ⇒page 186, the TCS monitors the speed of the drive
wheels. If the wheels start to spin, the engine speed is reduced automatically
to match the amount of grip available. The system is active across the entire
speed range.
The TCS works in conjunction with the ABS. If a malfunction occurs in the ABS,
the TCS will also be inoperative.
Note
To ensure that the TCS works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an undesired
reduction in engine power. Also see ⇒page 244.

change down into a lower gear or range (depending on the type of trans-
mission). This makes use of engine braking and relieves the brakes.
•Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.•Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.•If the brake fluid loses its viscosity and is subjected to heavy use,
vapour bubbles can form in the brake system. This reduces the efficiency of
the brakes.•Non-standard or damaged front spoilers could restrict the airflow to the
brakes and cause them to overheat. Before purchasing accessories please
observe the relevant instructions ⇒page 218, “Technical modifications”.•If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a qualified workshop immediately and avoid unnecessary
journeys.
Exhaust gas purification systemCatalytic converter*To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages the catalytic converter.
– Do not let the fuel get too low in the tank. – For engine oil changes, do not replenish with too much engine oil
⇒page 226.
– Never tow the vehicle to start it, use jump leads if necessary ⇒page 284.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest qualified workshop. In general, the exhaust gas warning lamp will
light up when any of the described symptoms occur ⇒page 66. If this
happens, unburnt fuel can enter the exhaust system and escape into the envi-
ronment. The catalytic converter can also be damaged by overheating.
WARNING
The catalytic converter reaches very high temperatures! There is a risk of
fire.•Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.•Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust
system. These materials could catch fire when the vehicle is being driven.Caution
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends

solved by changing to another brand of fuel.Diesel engine particulate filter*
The diesel engine particulate filter eliminates soot produced
by burning diesel.The diesel engine particulate filter eliminates most of the soot from the
exhaust gas system. Under normal driving conditions, the filter cleans itself.
If the driving conditions do not allow the filter to clean itself (for example,
multiple short trips) the filter will be obstructed by dust and pollen and the
indicator
for the diesel engine particulate filter indicator will light up. This
does not represent a fault, it is a warning that indicates that the filter has not
been able to regenerate automatically and that you must carry out a cleaning
cycle, as indicated in ⇒page 80.
WARNING
•The diesel engine particulate filter may reach extremely high tempera-
tures; the vehicle should be parked so that the exhaust pipe does not come
into contact with flammable materials underneath the vehicle. Otherwise
there is a risk of fire.Caution
•Your vehicle is not designed to use biodiesel fuel. Never, under any
circumstances refuel with biodiesel. The use of biodiesel fuel could damage
the engine and the fuel system. The addition of biodiesel to diesel by the
diesel producer in accordance with standard EN 590 is authorised and will
not cause damage to the engine or the fuel system.
•Using diesel fuel with a high sulphur content may significantly reduce the
working life of the diesel particulate filter. Your Authorised Service Centre will
be able to tell you which countries have diesel with a high sulphur content.Economical and environmentally friendly
drivingEconomical and environmentally friendly drivingFuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an econom-
ical driving style and anticipating the traffic situation ahead, you can easily
reduce fuel consumption by 10-15%. Some tips on how to help you reduce
pollution while saving money are listed below.
Drive anticipating the traffic situation
A vehicle uses most fuel when accelerating. When you anticipate the situa-
tion, you have to brake less often and, thus, accelerate less. If it is possible,
let the vehicle roll with a gear engaged, for example, if you see a red light
ahead. The braking effect achieved in this way helps to reduce the wear of
brakes and tyres; emissions and fuel consumption are reduced to zero
(disconnection due to inertia).
Change gear early to save energy
An effective way of saving fuel is to change up quickly through the gears.
Running the engine at high rpm in the lower gears uses an unnecessary
amount of fuel.
Manual gearbox: Change from first to second gear as quickly as possible. We
recommend that, whenever possible, you change to a higher gear upon
reaching 2000 rpm. Follow the recommended gear indication that appears on
the instrument panel ⇒page 73.

Operating Instructions
Practical Tips
Technical Specifications
Avoid driving at high speed
We advise you not to drive at the top speed permitted by the vehicle. Fuel
consumption, exhaust emissions and noise levels all increase very rapidly at
higher speeds. Driving at moderate speeds will help to save fuel.
Avoid idling
It is worthwhile switching off the engine when waiting in a traffic jam, at level
crossings or at traffic lights with a long red phase. The fuel saved after only
30 - 40seconds is greater than the amount of fuel needed to restart the
engine.
The engine takes a very long time to warm up when it is running at idling
speed. Mechanical wear and pollutant emissions are also especially high
during this initial warm-up phase. It is therefore best to drive off immediately
after starting the engine. Avoid running the engine at high speed.
Periodic maintenance
Periodic maintenance work guarantees that, before beginning a journey, you
will not consume more than the required amount of fuel. A well-serviced
engine gives you the benefit of improved fuel efficiency as well as maximum
reliability and an enhanced resale value.
A badly serviced engine can consume up to 10% more fuel than necessary.
Avoid short journeys
To reduce the consumption and emission of polluting gases, the engine and
the exhaust filtration systems should reach the optimum
service tempera-
ture .
With the engine cold, fuel consumption is proportionally higher. The engine
does not warm up and fuel consumption does not normalise until having
driven approximately four kilometres. This is why we recommend avoiding
short trips whenever possible. Maintain the correct tyre pressures
Bear in mind that keeping the tyres at an adequate pressure saves fuel. If the
tyre pressure is just 1 bar too low, fuel consumption can increase by as much
as 5%. Due to the greater rolling resistance, under-inflation also increases
tyre wear
and impairs handling.
The tyre pressures should always be checked when the tyres are cold.
Do not use winter tyres all year round as they increase fuel consumption by
up to 10%.
Avoid unnecessary weight
Every kilo of extra weight will put up the fuel consumption, so it is worth
checking the luggage compartment occasionally to make sure that no unnec-
essary loads are being transported.
A roof rack is often left in place for the sake of convenience, even when it is
no longer needed. At a speed of 100-120km/h your vehicle will use about
12% m ore fuel as a result of the extra wind resistance caused by the roof rack
even when it is not in use.
Save electricity
The engine activates the alternator, which produces electricity. With the need
for electricity, fuel consumption is also increased. Because of this, always
turn off electrical components when you do not need them. Examples of
components that use a lot of electricity are: the fan at high speeds, the rear
window heating or the seat heaters*.
Note
•If you vehicle has Start-Stop, it is not recommended to disconnect this
function.•It is recommended to close the windows when driving at more than 60
km/h
