130Lights and visibility
–In vehicles equipped with a rain sensor*, you can move the
switch A
up and down to set the sensitivity of the rain sensor.
Slow wipe
– Move the lever up to position 3
.
Continuous wipe
– Move the lever up to position 4
.
Automatic wash and wipe
– Pull the lever towards the steering wheel, 5
, to activate the
windscreen washer.
– Release the lever. The washer will stop and the wipers will keep
running for approximately 4 seconds.
Deactivating the windscreen wiper
– Pull the lever to basic position 0
.
General notes
The washers and wipers will work only when the ignition is switched on.
If you stop briefly, e.g. at traffic lights, the wiper speed will automatically be
reduced. The rain sensor* will automatically be set to the intermittent wipe
function.
The windscreen washer jets are heated when the ignition is switched on.
The wiper intervals in the intermittent wipe setting are also varied automati-
cally according to the road speed (in addition to the manual delay setting).
When the lights are switched on you should only pull the lever briefly to
wash the windscreen, otherwise the headlight washers* will also be ena-
bled. This will use an unnecessary amount of fluid from the reservoir. Rain sensor
The rain sensor* will only function in the intermittent wipe position. The in-
termittent wipe function is enabled automatically when it starts to rain.
If the windscreen wiper lever was in the intermittent wipe position when the
ignition was off, the rain sensor will not activate until you reach a speed of
6 km/h.
Use switch
A
to set the sensitivity of the rain sensor*.
If you have selected a high sensitivity level for the rain sensor the wind-
screen wipers will react sooner to any moisture on the windscreen.
The wiper intervals in the intermittent wipe setting are also varied automati-
cally according to the road speed (in addition to the sensitivity setting).
WARNING
● For correct visibility and safe driving, the wiper must be in perfect
condition ⇒ page 220. Failure to do so could result in an accident.
● The rain sensor* is only intended to assist the driver. The driver is
still obliged to manually operate the windscreen wipers as required de-
pending on visibility.
● Do not use water-repellent coatings on the windscreen. In bad visibili-
ty conditions such as light rain, low sun or when driving at night, these
coatings can cause increased dazzle, which is a serious safety hazard.
Such coatings can also cause the wiper blades to make noise.
CAUTION
● In the event of frost, check that the wiper blade has not frozen before
activating the windscreen wipers. Should the windscreen wiper system be
enabled when the blade is frozen, this could damage it or even the wind-
screen wiper system motor.
● Make sure you switch off the windscreen wiper system (lever in position
0) before you use an automatic car wash. This will avoid inadvertent trigger-
ing of the wipers and possible damage to the wiper system. 

tomatically according to the amount of light it receives. The anti-dazzle
function is disabled if:
● the interior lighting is switched on
● reverse gear is engaged
Sensors for automatic headlights*
When the light switch is set to the AUTO position, the dipped beam head-
lights are switched on and off automatically according to the ambient light
level with the aid of the sensors located in the interior mirror ⇒ page 118.
WARNING
Electrolyte fluid can leak from a broken mirror. This fluid can cause irrita-
tion to the skin, eyes and respiratory organs. Wash thoroughly with clean
water should you come into contact with this fluid. Seek medical assis-
tance if needed!
CAUTION
Electrolyte fluid leaking from a broken mirror can cause damage to plastic
surfaces. Use a sponge or similar to remove the fluid as soon as possible.
Note
● The interior mirror automatic anti-dazzle function* will only work proper-
ly if the sun blind* for the rear window is retracted and if there are no other
objects preventing light from reaching the mirror.
● If you have to stick any type of sticker on the windscreen, do not do so in
front of the sensors. Doing so could prevent the automatic headlight or anti-
dazzle function from working correctly or even from working at all. 

Air conditioning
Note
If the diode on the ECON button continues to light up when the ECON mode
has been switched off (i.e. the air conditioner has been switched on) this is
due to a defect in one of the air conditioner components. If a malfunction
should occur, please contact a specialised workshop. 
Air recirculation: automatic activation* 
If the outside air is polluted by diesel and petrol emissions,
an air quality sensor in the vehicle will automatically switch
on the air recirculation.
Fig. 140 Button for auto-
matic air recirculation
Activating air recirculation mode
– Press the button 

⇒ 
Fig. 140.
Deactivating air recirculation mode
– Press the 
button again or –
Press the AUTO
button or
– Press button 
.
The automatic air recirculation mode should normally be left switched on at
all times.
The system is ready to operate approx. 30 seconds after the engine ignition
key has been turned. During this initial period, fresh air is fed into the vehi-
cle.
If the air purity sensor in the air conditioner detects a certain concentration
of fumes in the outside air, the control unit will either pass the incoming air
through the pollution filter or automatically switch on the air recirculation. If
there is a high concentration of pollution in the outside air, the air condi-
tioner automatically switches to air recirculation and the supply of air from
the outside is cut off. As soon as the level of pollution decreases, air is fed
into the vehicle from the outside again.
The automatic air recirculation operates for a maximum period of 12 mi-
nutes. If the windows mist up when the automatic air recirculation is on,
press the 
button immediately.
The automatic air recirculation switches itself off under certain circumstan-
ces (for instance if 
or  is selected). In “ECON” and at temperatures
lower than approx. 8°C below zero, the automatic air recirculation mode is
limited to 12 seconds. 

170Air 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. 141
to ensure the best possible ventilation.
The blower only works when the sunroof is closed or tilted open at the rear. 

173
Driving
The Electronic Stability Control (ESC) contains the electronic differential lock
(EDL) and the traction control system (ASR). The ESC works together with
the ABS. If a fault in the ABS occurs, both warning lamps light up, but if the
ESC fails, only the ESC warning lamp lights up.
The ESC system is started automatically when the engine is started.
The ESC system is always active and cannot be switched off. The ESC switch
only switches the ASR off.
The ASR can be deactivated when wheel spin is desirable.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose surfaces.
● When the vehicle is stuck, to rock it backwards and forwards.
Press the button to switch the ASR back on when you no longer need wheel
spin.
Situations in which the warning lamp lights 
●
On switching the ignition on, it lights up for about two seconds to carry
out a function control.
● The warning lamp will start flashing when the vehicle is moving if the
ESC or the ASR is activated.
● It will light up continuously if there is a fault in the ESC.
WARNING
● Do not forget that the electronic stability control ESC cannot defy the
laws of physics. This should be kept in mind, particularly on slippery and
wet roads and when towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
● Please refer to the corresponding warning notes on ESC in
⇒ page 195, Intelligent technology.

Safety FirstOperating InstructionsPractical TipsTechnical Specifications

174Driving
Position 1
The ignition key is inserted in this position. To
engage the steering wheel
lock, take out the key and turn the wheel until you hear the pin engage. You
should always engage the steering lock when you leave the vehicle. This
will help to deter thefts ⇒ 
.
Switching on the ignition/pre-heating glow plugs 2
If the key is difficult to turn in the lock, move the steering wheel (to take the
load off the steering lock mechanism) until the key turns freely. In the case
of vehicles with a diesel engine, the key is turned to this position to preheat
the glow plugs.
Starting the engine 3
The engine is started in this position. Electrical components with a high
power consumption are switched off temporarily.
After the engine has started, the ignition key returns to position 2
by itself.
The ignition key has to be turned back to position 1
before re-starting the
engine. The starter inhibitor in the ignition lock prevents the starter motor
from engaging when the engine is running, as this could cause damage.
Switching off the ignition 1
Turn the ignition key to this position.
WARNING
● Never remove the ignition key until the vehicle is stationary! Other-
wise the steering lock could engage suddenly, which could cause an acci-
dent.
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
Note
● If the battery has been disconnected and then reconnected, it will be
necessary to leave the key in position 2
for about 5 seconds before start-
ing the engine.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). The selector lever is locked after the ignition key has been re-
moved. 

– Manual gearbox: Push the clutch pedal all the way down.
– Move the gear lever into neutral (automatic gearbox: selector
lever to P or N) ⇒ 
.
– Turn the ignition key to position 3
without pressing the accel-
erator.
– Release the ignition key as soon as the engine starts (the start-
er motor must not be allowed to run on with the engine).
Vehicles with a diesel engine:
– Use the foot brake.
– Manual gearbox: Push the clutch pedal all the way down. Other-
wise, the engine will not start.
– Move the gear lever into neutral (automatic gearbox: selector
lever to P or N) ⇒ 
.
– Turn the ignition key to position 2
. The pre-heating indicator
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 lamp will only light up 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. 
