Air conditioning
Air directed to windows
This setting directs all the air to outlets 1 and 2. Unlike in setting , the
volume of air delivery remains the same.
Air to the driver/front passenger
All the air comes from outlets 3 and 4 in the dash panel and from the rear of
the centre console.
Air to the footwells
Most of the air emerges from outlets 5 and the outlets under the front seats.
Some of the air will also be issued from outlets 3 and 4.
Note
In all of the above air distribution settings, a small amount of air will still
come from the other outlets.
Economical use of the air conditioner
Economical use of the air conditioner will help save fuel.
Engine power is reduced and fuel consumption increases when the
air conditioner is in cooling mode. To ensure that the system is on-
ly switched on when it is really necessary, please note the follow-
ing points:
– Select ECON mode if you wish to save fuel.
– Select ECON mode if you decide to open the windows or sun-
roof* while driving.
– If the vehicle has heated up after standing in the sun, open the
windows and doors for a short time to cool the vehicle.
For the sake of the environment
By saving fuel you also reduce the amount of pollutants emitted from your
vehicle.
Key settings
When the ignition is switched on, the air conditioner set-
tings assigned to the key are selected automatically.
The air conditioner settings selected are automatically stored and assigned
to the key in use. When the vehicle is started, the air conditioner automati-
cally selects the settings assigned to the key. Hence, every driver automati-
cally obtains his/her preferred settings without having to select them man-
ually.
Note
Should another driver use the key and enter other settings, the previous
settings will be deleted.
Solar-powered blower/sunroof*
If the vehicle is parked in sufficiently strong sunlight, the
blower will operate in solar-powered mode when the igni-
tion is switched off.
After the ignition is switched off, the blower is supplied with electrical pow-
er from the sunroof. Please ensure that outlets 3 and 4 are open ⇒ fig. 132
to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear.

If the air recirculation mode is on when you switch off the engine, the air
conditioner will automatically switch to fresh air ventilation.
Auxiliary heater*
Diesel vehicles are fitted with an auxiliary heater 1)
to raise the temperature
of the interior as quickly as possible. At outdoor temperatures below +5 °C
and with the engine running, the auxiliary heater will switch on and off auto-
matically depending on the temperature of the coolant.
In order to save fuel, the auxiliary heater can be can be switched off by brief-
ly pressing the

light comes on while the glow plugs are preheating.
– When the indicator light
goes out, turn the ignition key to
position 3
. Do not press the accelerator.
– Having completed the previous action the key can be released
immediately, it will return to position 2
and the engine will
have started.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern. If the engine fails to start straight away, stop after 10 seconds and try again
after about half a minute.
Glow plug system*
To assist starting at low temperatures,
diesel engines are equipped with a
glow plug preheating system. The preheating time depends on the coolant
temperature and the outside temperature. Start the engine as soon as the
glow plug indicator light goes out.
When the engine is warm or at outside temperatures above +8 °C, the glow
plug indicator light will only come on for about one second. This means that
the engine can be started immediately.
If the engine will not start...

WARNING
Never run the engine in confined spaces, as the exhaust gases are poi-
sonous.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle station-
ary. Start immediately. This will help avoid unnecessary exhaust emissions.

Engaging the reverse gear
– The vehicle should be stationary with the engine idling. Press
the clutch down thoroughly.
– Place the gear lever into neutral and push the lever downwards.
– Slide the gear lever to the left, and then into the reverse posi-
tion shown on the gear lever.
The reverse gear can only be engaged when the vehicle is stationary. When
the engine is running and before engaging this gear, wait about 6 seconds
with the clutch pressed down thoroughly in order to protect the gearbox.
The reverse lights light up when the reverse gear is selected and the igni-
tion is on.
WARNING
● When the engine is running, the vehicle will start to move as soon as
a gear is engaged and the clutch released.
● Never select the reverse gear when the vehicle is in motion. Risk of
accident.
Note
● Do not rest your hand on the gear lever while driving. The pressure of
your hand could cause premature wear on the selector forks in the gearbox.
● When changing gear, you should always depress the clutch fully to
avoid unnecessary wear and damage.
● Do not hold the car “on the clutch” on hills. This causes premature wear
and damage to the clutch.
● Do not leave your foot on the clutch pedal; although the pressure may
seem insignificant, it can cause the premature wear of the clutch plate. Use
the foot rest when you do not need to change gear.
Automatic gearbox* Introduction
multitronic ®
, tiptronic (7-speed gearbox)
Vehicles with multitronic ®
gearbox
The vehicle is equipped with an electronically controlled continuously varia-
ble transmission (multitronic ®
). Unlike conventional automatics, the gear
ratios are not shifted in fixed steps but continuously variable. This gives
smoother transmission and makes for better fuel economy.
179
Driving
To 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 depend-
ing 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 ve-
hicle 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 182, 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 vehi-
cle 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
WARNING (Continued)
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 im-
mediately (in some cases even if the parking brake is engaged) and pos-
sibly 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 221, Work in the engine compartment.
Note
● Applies to vehicles with tiptronic gearbox:
● If the lever is moved accidentally to N when driving, release the accelera-
tor 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.

Driving
Vehicles with tiptronic gearbox
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.
Dynamic gear control programme (DCP)
The automatic gearbox is controlled electronically.
The vehicle is equipped with an electronically controlled gearbox. The gear
ratios are selected automatically according to preset gearshift programmes.
When you drive at moderate speeds the gearbox will select the most eco-
nomical shift programme. It will then change up early and delay the down-
shifts to give better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the throt-
tle quickly, or if you use the kick-down or the vehicle's maximum speed, the
gearbox will automatically select the sport programme.
The gearbox is self-adapting, and continuously selects the most suitable
shift programme. At the same time, the driver can also make the gearbox
switch to the sport programme by pressing the accelerator quickly. This
makes the gearbox shift down into a lower gear ratio, allowing a more rapid
acceleration (for instance to pass another vehicle), without having to press
the accelerator all the way down into the kick-down position. After the gear-
box has shifted back up it returns to the original programme, depending on
your style of driving. Vehicles with multitronic® gearbox: the gearbox continuously adapts the
gear ratios to gradients. If the brake pedal is pressed on a downhill gradient
the gearbox automatically shifts to a lower gear ratio. This increases the en-
gine braking effect.
Vehicles with tiptronic gearbox: in mountainous areas, the gearbox adapts
the gears for uphill and downhill gradients. This helps to avoid constant
gear changes on uphill gradients.

192Driving and the environment
WARNING (Continued)
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). 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, va-
pour 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 215, Technical modifi-
cations.
● If a brake circuit fails, the braking distance will be increased consider-
ably. Contact a specialised workshop immediately and avoid unnecessa-
ry journeys.
Exhaust gas purification system Catalytic 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 224.
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 280.
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 specialised 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 en-
vironment. 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 sys-
tem. 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
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel.
193
Driving and the environment
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 ex-
haust 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 temper-
atures; the vehicle should be parked so that the exhaust pipe does not
come into contact with flammable materials underneath the vehicle. Oth-
erwise there is a risk of fire.
CAUTION
● Your vehicle is not designed to use biodiesel fuel. Never, under any cir-
cumstances 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 Cen-
tre will be able to tell you which countries have diesel with a high sulphur
content. Economical and environmentally friendly
driving
Economical and environmentally friendly driving
Fuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends in large part on your driving style. By adopting an eco-
nomical 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 (dis-
connection 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 ap-
pears on the instrument panel ⇒ page 73.
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.
