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 vehicles with separate lights for daylight driving lights in the fog lights or in
the front bumper, the low beam does not light up when the light switch is in posi-
tion 0 even if the ignition is switched on.
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.

Rain lights
If you switch on the windscreen wipe in the operation rain sensor for longer than
10 seconds or in the operation permanent wipe (position
2 or 3) ⇒ page 53
switching on for longer than 15 seconds, the side lights and low beam are switch-
ed on automatically. The light switches off if the windscreen wipe is in operation
rain sensor for more than around 4 minutes or is not switched on in the operation
permanent wipe. WARNING
The automatic light control only operates as a support. The driver is not re-
leased from his responsibility to inspect the light and if necessary to switch on
the light depending on the light conditions. The light sensor cannot detect for
example rain or snow. For these conditions we recommend to switch on the
low beam ! 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 44.
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 10
km/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.
The parking light only operates if the ignition is switched off.
If you have switched on the right or left turn signal light and you switch off the
ignition, the parking light is not automatically switched on.

Adjusting in forward/back direction
– Push the lid into the desired position.
Opening air inlet
– Pull the lock A in upward direction.
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

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

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 206
, 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 211.
● 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 211.
● 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. 99 . 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. £100
Starting-off and Driving
Shifting gears and saving energy
Shifting up early saves on fuel.
Fig. 142 Fuel consumption in litres/100
km and speed in km/h.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear.
– Shift up into the next higher gear at approx. 2 000 to 2 500 revs.
An effective way of achieving good fuel economy is to shift up early . You will con-
sume more fuel if you drive at unnecessarily high revolutions in any given gear. To
shift in a fuel-efficient manner, follow ⇒
page 13, Shift recommendation for chang-
ing gears.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it beyond the kickdown
position, however.
Only depress the accelerator pedal slowly if your vehicle is fitted with an automat-
ic gearbox in order to automatically select an economic driving programme. You
will achieve good fuel economy by shifting up early and shifting down late.
General
The ⇒ fig. 142 shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st
gear is the highest, while that in 5th or
the 6th gear is the lowest. Note
Also use the information supplied by the multi-functional indicator ⇒ page 14.Avoiding full throttle Driving more slowly means saving fuel.
Fig. 143 Fuel consumption in litres/100
km. and speed in km/h.
Sensitive use of the accelerator will not only significantly reduce fuel consumption
but also positively influence environmental pollution and wear of your vehicle.
You should avoid exploiting the top speed of your vehicle wherever possible. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The ⇒ fig. 143 shows the ratio of fuel consumption to the speed of your vehicle.
You will cut your fuel consumption by half if you only make use three-quarters of
the possible top speed of your vehicle.
Reducing idling Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at a level
crossing or at traffic lights with a lengthy red phase. Even after just 30 - 40 sec-
onds you will have saved more fuel than that is needed when you start the engine
up again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly high
in the warming-up phase. This is why you should drive off right after starting the
engine. Do avoid high engine revolutions at this time, however. 163

Driving Tips
–
Do not, as far as possible, drive with your vehicle unladen and the trailer laden.
– Do not make full use of the legal maximum speeds. This applies in particular to
downhill sections.
– Apply the brakes in good time.
– Keep a check on the coolant temperature gauge if the outside temperature is
high.
Distribution of weight
The distribution of the weight is very poor if your vehicle is unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this
combination.
Driving speed
Do not drive faster than 80 km/hour for safety reasons. This also applies for coun-
tries in which higher speeds are allowed.
The fact that the driving stability of the vehicle + trailer combination reduces with
increasing speed means that the legally allowed speed should not be used when
there are unfavourable road, weather or wind conditions, particularly near acci-
dent black spots.
You must always reduce your speed immediately as soon as you detect even just
the slightest swaying of the trailer. On no account attempt to stop the trailer
from “swaying”
by accelerating.
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply the
brakes gently at first and then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking. Shift down gears in good time before negotiating
a downhill section to allow the engine to also act as a brake.
Engine overheating
Please keep a check on the coolant temperature gauge if you have to negotiate a
lengthy slope in a low gear at a high engine speed when the outside temperature
is very high ⇒ page 11, Coolant temperature gauge.
If the needle of the coolant temperature gauge moves into the right-hand area or
even the red area of the scale, reduce your speed immediately. Stop and switch
off the engine if the warning light in the instrument cluster begins flashing.
Wait a few minutes and check the level of coolant in the coolant expansion bottle
⇒ page 185, Inspecting the coolant level. Please refer to the following guidelines
⇒ page 25, Coolant temperature/ Coolant
quantity .
The coolant temperature can be reduced by switching on the heating.
Any increase in the cooling effect of the coolant fan through shifting down a gear
and increasing the engine speed is not possible since the fan speed is independ-
ent of the engine speed. One should also not drop a gear for this reason when
towing a trailer as long as the engine can manage the slope without any drop in
speed. 169
