– Turn the light switch into position.
The dipped beam continues to shine while the ignition is switched on and the
light switch is in the position or . After switching off the ignition, the low
beam is switched off automatically and only the side lights come on. The parking
light also goes out after the ignition key is removed.
On models fitted with right-hand steering the position of certain switches differs
from that shown in ⇒
fig. 24. The symbols which mark the switch positions are
identical, however. WARNING
Never drive with only the side lights on - risk of accident! The side lights are
not bright enough to light up the road sufficiently in front of you or to be seen
by other oncoming traffic. In this case, always switch on the low beam when it
is dark or if visibility is poor. Note
● If the light switch is in the position , the ignition key is removed and the
driver's door is open, an acoustic warning signal will sound. The acoustic warning
signal is switched off over the door contact when the driver's door is closed (igni-
tion off). The vehicle can be parked with the side lights on.
● If the light switch is in the position and the ignition key is removed, the
lights will go out.
● If the car is parked for a lengthy period, we recommend switching off all lights,
or leaving only the parking lights switched on.
● The switching on of the described lights should only be undertaken in accord-
ance with the legal requirements.
● If a fault occurs in the light switch, the low beam comes on automatically
● In the event of cool or humid weather conditions, the headlights can be misted
up from inside.
–The temperature difference between interior and external area of the head-
light lenses is decisive.
– When the driving lights are switched on, the light outlet surfaces are free
from mist after a short period. The headlight lenses can possibly mist up at the
border areas.
– It also concerns reverse light and turn signal lights.
– This mist has no influence on the life of the lighting system.

Note
● Do not affix any stickers in front of the light sensor, so that you do not impair
its function or put it out of operation.
● The same principles as for using the automatic light control also apply to the
light which is switched on manually ⇒
page 45.
Cornering lights The cornering lights are used to illuminate the curves by means of the cone of
light swivelling together with the front headlight with Xenon lights. This function
is active when the speed of the car increases to more than 10km/h.
The swivelling function of the headlights can be switched off/on via the menu
point Assistants in the main menu of the information display ⇒ page 18
.WARNING
If the cornering lights are defective, the headlights are automatically lowered
to the emergency position, which prevents a possible dazzling of oncoming
traffic. Thus the illuminated length of the road is shortened. Drive carefully
and have the car inspected immediately by a specialist garage.
Parking light Parking light
– Switch off the ignition.
– Pull the turn signal light lever ⇒
fig. 30 upwards or downwards - the parking
light on the right and left side of the vehicle will be switched on respectively.

low beam illuminates.
– Switch off the ignition.
– After opening the driver's door, the function Coming Home is switched on.
– Close all the doors and the boot lid and lock the vehicle. After a short time,
switch all lights off.
Depending on equipment fitted the function Coming Home switches on the fol-
lowing lights:
● Parking lights,
● Low beam,
● Entry lighting in the exterior mirrors,
● Licence plate light.
Coming Home Function
The lights go out 10 seconds after closing all the doors and the boot lid.
If a door or the boot lid remains open, the lights go out 60 seconds after switching
off the ignition.
The function Coming Home is controlled with the light sensor in the mount of the
interior rear mirror. If the light intensity is higher than the set value of the light
sensor, the Coming Home Function is not switched on after switching off the igni-
tion. Note
● If the Coming Home Function is switched on constantly, the battery will be
heavily discharged particularly in short-haul traffic.
● The switching on of the described lights should only be undertaken in accord-
ance with the legal requirements.

Folding table on the middle seat backrest
Fig. 55 Rear seats: Armrest
– The middle seat backrest can be folded ⇒ page 67, Folding rear seats forwards
forwards and used as armrest or table with cup holder ⇒ fig. 55 .
– You can place two cups or beverage cans into the recesses. WARNING
● Do not place any hot beverages into the cup holder. If the vehicle moves,
they may spill - risk of scalding!
● Do not use any cups or beakers which are made of brittle material (e.g.
glass, porcelain). This could lead to injuries in the event of an accident. CAUTION
Do not open the beverages in the cup holder while driving. There is a risk of spill-
ing e.g. when braking and therefore the electrical components or the seat uphols-
tery can be damaged. Note
If the middle rear seat backrest should be folded forward for lengthy periods, then
make sure that the belt locks are not located below it - this can result in perma-
nent damage to the upholstery. Seat heating of the front seats Fig. 56 Dash panel: Regulator for front
seat heating
You can electrically heat the seat cushions and the seat backrests of the front
seats.
Front seats
– You can switch on and regulate the seat heating of the driver or front passen-
ger seat by pressing the surface of the regulator at the point at which the
symbol is located ⇒
fig. 56 .
– With one press, you can switch the heating to highest intensity - 3rd stage,
which is indicated by the lighting up of the three warning lights in the switch.
– With repeated pressing of the switch, the intensity of the heating is down-
regulated up to the switch-off. The intensity of the heating is indicated by the
number of illuminated warning lights in the switch. WARNING
If, as an occupant, you have a subdued pain and/or temperature sensitivity,
e.g. through medication, paralysis or because of chronic illness (e.g. diabetes),
we recommend not to use the seat heating. This can lead to burns on the
back, the posterior and the legs which are difficult to heal. If the seat heating
is used, we recommend to make regular breaks in your journey when driving
long distances, so that in specific cases as mentioned above the body can re-
cuperate from the stress of the journey. Please consult your doctor, who can
evaluate your specific condition. £ 69

Closing air inlet
– Push the lock A as far as the stop downwards.
On vehicles fitted with air conditioning, the storage compartment is equipped
with a lockable inlet for thermally treated (warmed-up) air.
At open air supply, air flows into the storage with a temperature which is as high
as the one out of the air outlet nozzles, depending on temperature setting.
The air inlet in the storage compartment is connected to position through ad-
justment of the control dial for air distribution. This position causes the maximum
amount of air to flow into the storage compartment (depending on the rotary reg-
ulator position for the fan).
You can use the storage compartment, for example, to temper drinks cans, etc.
If you do not use the air inlet in the storage compartment, the end cover should
always be kept closed. Note
Push the lid of the armrest up to stop to the rear before operating the handbrake. 83

conditions are met:
● engine running,
● outside temperature above approx. +2 °C and
● blower switch switched on (positions 1 to 4).
Air at a temperature of about 5 °C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of
the air flow out of the vents and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons. Note
● We recommend that you have the air conditioning system cleaned by a spe-
cialist garage once every year.

ing or heating capacity, respectively. The temperature is not controlled in this
case.
Lengthy and uneven distribution of the air flow out of the vents (in particular at
the leg area) and large differences in temperature, for example when getting out
of the vehicle, can result in chills in sensitive persons.
Recirculated air mode In recirculated air mode air is sucked out of the interior of the vehi-
cle and then fed back into the interior. When the automatic air dis-
tribution control is switched on, an air quality sensor measures the
concentration of pollutants in the drawn in air.
Recirculated air mode prevents polluted air outside the vehicle from getting into
the vehicle, for example when driving through a tunnel or when standing in a traf-
fic jam. If a considerable increase in concentration of pollutants is recognized by
the air quality sensor, when the automatic air distribution control is switched on,
the air distribution control will temporarily be switched off. If the concentration of
pollutants decreases to the normal level, the air distribution control is automati-
cally switched off so that fresh air can be guided into the vehicle interior.
Switching recirculated air mode on
– Press the button repeatedly until the warning light on the left side of the
button lights up.
Switch on automatic air distribution control
– Press the button repeatedly until the warning light on the right side of the
button lights up.
Switch off automatic air distribution control temporarily
– If the air quality sensor does not switch on the air distribution control auto-
matically when there is a nauseating smell, you can switch it on yourself by
pressing the button . The warning light lights up in the button on the left
side.
Switching recirculated air mode off
– Press the button AUTO or press the button
repetitively, until the warning
lights in the button go out. WARNING
You should not leave recirculated air mode on over a longer period of time, as
“stale ” air may result in fatigue in the driver and occupants, divert your atten-
tion and also cause the windows to mist up. The risk of having an accident in-
creases. Switch recirculated air mode off as soon as the windows begin mist-
ing up. Note
● If the windscreen mists up, press the button
1 ⇒
fig. 92 . After the wind-
screen has been demisted, press the button AUTO .
● The automatic air distribution control operates only if the outside temperature
is higher than approx. 2 °C.
Controlling blower There are a total of seven blower stages available.
The Climatronic system controls the blower stages automatically in line with the
interior temperature. You can also, however, adapt the blower stages manually to
suit your particular needs.
–
Press again the button on the left side (reduce blower speed) or on the
right side (increase blower speed).
If you switch off the blower, the Climatronic is switched off.
The set blower speed is displayed above the button when the respective num-
ber of warning lights come on. WARNING
● “Stale air
” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an acci-
dent increases.
● Do not switch the Climatronic system off for longer than necessary.
● Switch the Climatronic system on as soon as the windows mist up. 94
Heating and air conditioning system
CAUTION
● The starter may only be operated (ignition key position 3 ), if the engine is not
running. If the starter is immediately operated after switching off the engine, the
starter or the engine can be damaged.
● Avoid high engine revolutions, full throttle and high engine loads as long as
the engine has not yet reached its normal operating temperature - risk of damag-
ing the engine!
● Do not tow start the engine - danger of damaging the engine. On vehicles with
a catalytic converter, unburnt fuel may get into the catalytic converter where it
may ignite. This in turn may damage or destroy the catalytic converter. You can
use the battery of another vehicle as a jump-start aid ⇒ page 216, Jump-starting
.For the sake of the environment
Never warm up the engine when the vehicle is standing. Drive off right away.
Through this the engine reaches its operating temperature more rapidly and the
pollutant emissions are lower.
Petrol engines These engines are fitted with a starter system which selects the correct fuel-air
mixture for every external air temperature.
●
Do not operate accelerator before and when starting engine.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right awayand wait for about 30 seconds before repeating the attempt.
● It is possible that the fuse on the electrical fuel pump is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 220.
● Contact the nearest specialist garage to obtain professional assistance.
It may be necessary, if the engine is very hot, to slightly depress the accelerator
after the engine has started.
Diesel engines Glow plug system
Diesel engines are equipped with a glow plug system, the preglow period being
controlled automatically in line with the coolant temperature and outside temper-
ature.
The preglow indicator light comes on after the ignition has been switched on. You should not switch on any major electrical components during the heating
period otherwise the vehicle battery will be drained unnecessarily.
● You should start the engine immediately after the glow plug warning light
has gone out.
● The glow plug warning light will come on for about one second if the engine is
at a normal operating temperature or if the outside temperature is above +5 °C.
This means that you can start the engine right away.
● Interrupt the attempt at starting after 10 seconds if the engine does not start
right away and wait for about 30 seconds before repeating the attempt.
● It is possible that the fuse on the diesel preglow system is defect if the engine
still does not start. Check the fuse and replace it if necessary ⇒ page 220.
● Contact the nearest specialist garage to obtain professional assistance.
Starting the engine after the fuel tank has run dry
It may take longer than normal to start the engine after refuelling if the fuel tank
has run completely dry - up to one minute. This is because the fuel system must
first of all be filled while the attempting to start the engine.
Switching off the engine –
The engine can be switched off by turning the ignition key into position 1 ⇒
fig. 96 . WARNING
● Never switch off the engine before the vehicle is stationary - risk of acci-
dent!
● 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. CAUTION
you should not switch the engine off right away at the end of your journey after
the engine has been operated for a lengthy period at high loads but should be al-
lowed it to run at idling speed for about 2
minutes. This prevents any accumula-
tion of heat when the engine is switched off. £ 101

WARNING
● The parking aid is not a substitute for the driver paying proper attention
and it is always the driver's responsibility to take care when reversing the ve-
hicle or carrying out similar manoeuvres.
● You should therefore satisfy yourself, before reversing, that there is no
small obstacle, such as a rock, thin post, trailer drawbar etc., in front or behind
your vehicle. Such an obstacle might not be within the range detected by the
sensors.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the parking aid. Thus, these objects or
people who wear such clothing are not recognised by the sensors of the park-
ing aid. Note
● Only the front parking aid operates if you are towing a trailer (applies only to
models which feature a factory-fitted towing device).
● If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
confirmed additionally when the symbol flashes in the button
⇒ fig. 100 - left.
Have the fault rectified by a specialist workshop.
● The sensors must be kept clean and free of ice to enable the parking aid to
operate properly.
● If the parking aid is activated and the selector lever of the automatic gearbox
is in the position P , warning signal indicates interruption (vehicle can no longer
move).
Park Assist Description and important information The park assist assists you when parking in a suitable parallel parking space be-
tween two vehicles or behind a vehicle.
The park assist automatically searches for suitable parking spaces after switching
on the ignition and when driving up to 30 km/h.
During the parking procedure the park assist only takes over the steering move-
ments, the pedals continue to be operated by the driver. Function of the system is based on:
●
Length and depth measurement of the parking spaces when driving
● Evaluation of the size of the parking space
● Definition of the correct position of the vehicle for parking
● Calculating the line on which the vehicle drives backwards into the parking
space
● Actuation of the steering force assistance, automatic spinning of the wheels
of the front axle when parking. WARNING
The park assist does not take away the responsibility from the driver when
parking.
● Pay particular attention to small children and animals as they would not be
recognised by the sensors of the parking aid.
● Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the signal of the park assist or the parking aid. Thus,
these objects or people who wear such clothing are not recognised by the
sensors of the parking aid.
● The external sound source of the park assist and the parking aid can be
disruptively influenced and under unfavourable conditions, objects or people
cannot be recognised by the sensors of the parking aid. CAUTION
● If other vehicles are parked behind or on the kerb, the park assist guides your
vehicle beyond the kerb or onto it. Make sure that the wheels or the wheel rims of
your vehicle are not damaged and if necessary intervene in time.
● You should satisfy yourself before parking that there is no small obstacle, such
as a rock, thin post, trailer drawbar etc., in front or behind your vehicle. Such an
obstacle might not be within the range detected by the sensors.
● Under certain circumstances, surfaces or structures of certain objects such as
wire mesh fences, powder snow etc..., cannot be recognised by the system.
● The evaluation of the parking space and the parking procedure depends on
the circumference of the wheels. Under certain circumstances, the system may
not function correctly if your vehicle is mounted with wheels of non-permissible
size, snow chains or a temporary spare wheel (in order to reach the nearest work-
shop). If the tyres other than those excepted by the manufacturer are mounted,
the resulting position of the vehicle in the parking space can differ slightly. The
parking assistant system automatically performs the correction of the wheel cir-
cumference when driving. £ 105
