Note
If the battery has been disconnected
and reconnected, the warning light
comes on
after switching on the ignition. The warning light must go out after driving a short distance.Antilock brake system (ABS)
The warning light
shows the functionality of the ABS.
The warning light comes on for a few seconds after the ignition has been switched on or when starting the engine. The warning light goes out after an automatic check sequence has been completed. A fault in the ABS The system is not functioning properly if the ABS warning light
does not go out
within a few seconds after switching on the ignition, does not light up at all or lights up while driving. The vehicle will only be br
aked by the normal brake system. Visit a
specialist garage immediately and adjust your
style of driving appropriately as you will
not know how grea
t the damage is.
Further information about ABS
page 140, “Antilock brake system (ABS)”.
A fault in the entire brake system If the ABS warning light
comes on together with the brake system warning light
(handbrake must be released), there is a fa
ult not only in the ABS but also in another
part of the brake system
.
WARNING
If the brake system warning light
comes on together with the ABS
warning light
stop the vehicle immediately and check the brake fluid level in
the reservoir
page 171, “Brake fluid”. If the fluid level has dropped below the
MIN marking, do not drive any further - risk of accident! Obtain professional assistance.
Pay attention to the following instruct
ions before checking the brake fluid
level and opening the bonnet
page 166, “Working in the engine compart-
ment”.
If the brake fluid is at the correct leve
l, the ABS control function has failed.
The rear wheels may then block very rapi
dly when braking. In certain circum-
stances, this can result in the rear end of the car breaking away - risk of skid-ding! Drive carefully to the nearest sp
ecialist garage and have the fault
rectified.Brake system
The warning light
flashes or comes on if the brake fluid level is too low, if there is a
fault in the ABS or if
the handbrake is applied.
If the warning light
flashes and an audible signal so
unds three times (handbrake is
not applied),
stop
and check the brake fluid level
.
The following text will be displayed in the information display*:
Brake fluid: Owner's manual
If there is a fault in the ABS which also infl
uences the function of the brake system (e.g.
distribution of brake pressure), the ABS warning light
comes on and at the same
time the brake system warning light starts flashing
. Be aware that not only the ABS
but also another part of th brake system is defective
.
An audible signal sounds three times as an additional warning signal.One should get used to high pedal forces, an extended free play of the brake pedal and long braking distances when carefully driving to the specialist garage. For further information on the brake system
page 139, “Brakes”.
Handbrake applied The warning light
also comes on if the handbrake is applied. An audible warning is
also given if you drive the vehicle for at least 3 seconds at a speed of more than 6 km/h. The following text will be displayed in the information display*:

while driving
. This also applies if the warning
light does not come on after the
ignition is switched on. The following text will be displayed in the information display*:
Airbag fault!
The functionality of the airbag system is also monitored electronically when one airbag has been switched off. The following situation applies if the fr
ont, side and head airbags or belt
tensioner have been switched off
using the vehicle system tester:
The warning light
lights up for 3 seconds after switching on the ignition and then
flashes for 12 seconds afterwards in 2 second intervals. The following text will be displayed in the information display*:

up of the yellow indicator light in display
page 129.
WARNING
Have the airbag system checked immediat
ely by a specialist
garage if a fault
exists. Otherwise, there is a
risk of the airbag not bein
g activated in the event of
an accident.
Note
Further information about switching off airbags
page 128, “Deactivating airbags”.
Diesel particle filter*
(diesel engine)
If the warning light
comes on, this means that soot
has accumulated in the diesel
particle filter because of the frequent short distances. In order to clean the diesel particle filter, the vehicle should be driven at an even speed of at least 60 km/h at engine speeds of 1
800 - 2 500 rpm for at least 15 minutes or until
the warning light goes out with the 4th or
5th gear engaged (automatic gearbox: posi-
tion S) when the traffic situation permits it. This increases the exhaust temperature and the soot deposited in the diesel particle filter is burnt. Always pay attention to the valid speed limits
.
The warning light
goes out after the successful cleaning of the diesel particle filter.
If the filter is not properly
cleaned, the warning light
does not go out and the
warning light
begins to flash. In the in
formation display* appears
Diesel-particle
filter! Owner's manual
. Afterwards the engine control unit shifts the engine into the
emergency mode, which only has a reduced po
wer output. After switching the ignition
off and on again the warning light
comes on.
Have the vehicle inspected without
delay by your specialist garage.

Unlocking and locking
42The safe securing system along with the anti-theft alarm system* are, however, deac- tivated during these 30 seconds. When the vehicle is unlocked or locked, the interior lights in the door contact are auto- matically switched on or off. Display of the locking The turn signal lights flash once to confir
m that the vehicle has been correctly locked.
If the vehicle is locked by pr
essing the button and some doors or the boot lid are
not closed, the turn signal lights flash only after closing.
WARNING
If the vehicle is locked from the outside and the safe securing system is acti-vated, there must not be any person in the vehicle as it is then not possible to open either a door or a window from the inside. The locked doors make it more difficult for rescuers to get into th
e vehicle in an emergency - hazard!
Note
Operate the radio remote control only when
the doors and boot lid are closed and
you have visual contact with the vehicle.
Once in the vehicle, you must not press the lock button
of the master key before
inserting the key into the ignition lock in
order to avoid the vehicle being inadvertently
locked and the anti-theft alarm system* being switched on. Should this happen, press the unlock button
of the master key.
Syncronisation of the remote controlIf the vehicle cannot be unlocked by actuatin
g the remote control system then it is
possible that the code in the key and the co
ntrol unit in the vehicle are no longer
synchronised. This can occur when the buttons on the radio-operated key are actuated a number of times outside of the operative
range of the equipment or the battery on
the remote control was replaced. This means it is necessary to
synchronise the code as follows:
press any button on the remote control;
pressing of the button means that the door will unlock with the key within 1
minute.Anti-theft alarm system*DescriptionThe anti-theft alarm system increases the level of protection against people seeking to break into the vehicle. The system triggers audible and visual warning signals if an attempt is made to break into the vehicle. How is the alarm
system activated?
The anti-theft alarm system is activated au
tomatically when the
unlocked vehicle is
locked with the key inserted in the driver's
door or with the remote control key. It is
activated 30 seconds after locking the door. How is the alarm system deactivated? The anti-theft alarm system is deactivated if
the vehicle is unlocked by only using the
radio remote control. The anti-theft alarm system is reactivated if the vehicle is not opened within 30 seconds after transmitting the radio signal. Once you unlock the vehicle by inserting the ke
y into the driver door you then have to
insert the key into the ignition lock and sw
itch the ignition on within 15 seconds after
opening the door in order to deactivate the anti-theft alarm system. The
alarm will be
triggered
if you do
not switch on
the ignition within 15 seconds.

Heating and air conditioning system
86Using the air conditioning system economicallyThe compressor on the Climatic uses powe
r from the engine when in cooling mode
which will effect the fuel consumption. It recommended to open the windows or the
doors of a vehicle for which the interior
has been strongly heated through the effect
of direct sunlight in order to allow the
heated air to escape. The cooling system should not be switched
on while travelling when the window is
open. The desired interior temperature can also be achieved without switching in the cooling system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.Operational malfunctionsIf the cooling system does not operate at outside temperatures higher than +5 °C, there is a problem in the system. The reasons for this may be:
The fuse of the Climatic is defective. Check the fuse, replace it if necessary
page 195.
The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot
page 16.
If you are not able to rectify the operational
problem yourself, or if the cooling capacity
decreases, switch the cooling system off. Contact a specialist garage. If there is a fault at the Climatronic, all symbols on the display flash after switching on the ignition for 15 seconds. Contact a specialist garage.
Climatronic* (automatic air conditioning)Description The Climatronic system is a combinat
ion of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu- pants of the car.The Climatronic maintains a constant temperat
ure fully automatically, once it has been
set. This is achieved by automatically varying the temperature of the outflowing air, the blower stages and the air distribution. The system also takes into account sunlight which eliminates the need to
alter the settings manually. The
automatic mode
page 88 ensures maximum wellbeing of the
occupants at all times of the year.
Description of Climatronic system The cooling operates only if the following conditions are met:
engine running,
outside temperature above approx. +2°C,
switched on.
If the cooling system is switched on, th
e temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-ularly at high outside temperatures and a high air humidity. The system prevents the windows misting up during the cold season of the year. The heating effect is dependent upon the coolant temperature, thus full heat output only occurs when the engine has reached its operating temperature. It is possible to briefly activate recirculat
ed air mode in order to enhance the cooling
effect
.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to ensure that the heating and cooling systems operate properly. The AC compressor is switched off at a high
coolant temperature in order to provide
cooling at a high load of the engine. After switching on the cooling
Condensation

tioning may drip down and form a puddle be

WARNING
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin
g. Please familiarize yourself about
how to correctly operate th
e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.
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 attention and also cause the windows to mist up. The risk of having an accident increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on at
least once a month for approximately 5 minut
es at the highest blower stage - also
during the cold se aso n of the y ear - i n o rde
r to avoid such odours. Also open a window
for a short time.
We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the interior of the vehicle forms deposits in the evapor
ator of the air conditioning system. This
produces a permanent odour when the air co
nditioning system is operating which can
only be eliminated through considerable
effort and expense (replacement of
compressor).
The used air streams out through the air
removal openings in the luggage compart-
ment.

You can set the interior temperature betw
een +18°C (64°F) and +29°C (86 °F). The
interior temperature is regulated automatica
lly within this range. If you select the
temperature below +18°C (64°F), “LO” appears in the display. If you select the temper-ature higher than +29°C (86°F), “HI” appears
in the display. In both limit positions the
Climatronic operates at ma
ximum cooling 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.Controlling blower There are a total of seven blower stages available.The Climatronic system controls the blower st
ages automatically in
line with the inte-
rior temperature. You can also, however, adap
t the blower stages manually to suit your
particular needs. – Turn the control dial
page 87, fig. 92
to the left (reduce blower speed) or right
(increase blower speed).
If you switch off the blower, th
e Climatronic is switched off.
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 accident increases.
Do not switch the Climatronic system off for longer than necessary.
Switch the Climatronic system on as soon as the windows mist up.
