Auto Check ControlCar stateThe Auto Check Control carries out a check of certain functions and vehicle compo- nents. The check is performed constantly
when the ignition is switched on, both
when the vehicle is stationary, as well as when driving. Operational faults, urgent repairs, service
work or other information appear in the
display of the instrument cluster. The disp
lays are shown with a red or yellow light
symbol depending on the priority of the message. The red symbols indicate
danger
(priority 1) while the yellow symbols indicate a
warning
(priortity 2). Information for the driver
may also appear in addition to the
symbols
⇒page 27.
Investigate the displayed faults as soon as
possible. If several operational faults exist
at the same time, the symbols will appear
one after the other and are each visible
for about 2 seconds. The error messages are faded out after 10 seconds or by actuating the rocker switch ⇒page 24, fig. 26
and are stored under the information
CAR STATUS
.
There is at least one error message to be read when the term
CAR STATUS
is
flashing in the menu. The display will show
STATUS 1/2
(for example) if a number
of error messages are present. This display
indicates that the first of a total of two
error messages should be displayed. Actuate the rocker switch , to call up the individual error messages.If a fault occurs, a warning signal will also sound in addition to the symbol and text in the display:•
Priority 1 - three warning signals
•
Priority 2 - one warning signal
Red symbols A red symbol signals danger.Proceed as follows if a red symbol is displayed: – Stop the vehicle.– Switch the engine off. – Check the functions indicated. – Obtain professional assistance.Meaning of the red symbols: Three
successive warning signals will sound if a red symbol appears. The symbol
continues flashing until
the fault is rectified.

WARNING
•
If you do not pay attention to the wa
rning lights coming on and the corre-
sponding descriptions and warning notes, this may result in severe body injuries or major vehicle damage.•
The engine compartment of your car is
a hazardous area. There is a risk
of injuries, scalding, accidents and
fire when working in the engine
compartment, e.g. inspecting and replenis
hing oil and other fluids. It is also
essential to obse
rve all warnings
⇒page 160.
Note
•
Arrangement of the indicator lights depends on the model and model version.
The symbols shown in the following function
al description are to be found as indi-
cator lights in the instrument cluster.•
Operational faults are shown in the inst
rument cluster as red symbols (priority
1 - danger) or yellow symbols (priority 2 - warning).Turn signal system
Either the left
or right
indicator light flashes depending on the position of the
turn signal lever. The indicator light flashes at twice its normal rate if a turn signal light fails. This does not apply when towing a trailer. Switching off the hazard warning light system is switched on will cause all of the turn signal lights as well as both indicator lights to flash. Further information about the turn signal system
⇒page 52.
Turn signal system for vehicles towing a trailer

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 ig
nition, does not light up at all or lights
up while driving. The vehicle
will only be braked by th
e normal brake system. Visit
a specialist garage as quickly as possible and adjust your style of driving to take account of the fault in the meantime since
you will not know the extent of the fault
and in how far the effect of the antilock brakes is affected. Further information about ABS

Wet roads or road salt There may be a certain delay before the br
akes take full effect under certain condi-
tions such as when driving through water,
during heavy rain
showers or after the
vehicle has been washed in
an automatic vehicle wash, since the brake discs and
brake pads may be moist or even have a
coating of ice on them in winter. You
should dry the brakes as soon as possib
le by applying and releasing the brakes
several times. There also may be a certain delay before the
full braking efficiency is available when
driving on roads which have been treated wi
th road salt if yo
u have not used the
brakes for some considerable time beforeha
nd. The layer of salt on the brake discs
and brake pads must first be rubb
ed off when you apply the brakes.
Corrosion Corrosion on the brake discs and dirt on th
e bake pads occur if
the vehicle has been
parked for a long period and if you do
not make much use of the braking system.
We recommend cleaning the brake discs by
firmly applying the brakes at a fairly
high speed if you do not make much use of the braking system or if surface corro-sion is present
⇒
.
Faults in the brake surface If you notice that the braking distance has suddenly become longer and that the brake pedal can be depressed further, it is
possible that a brake circuit of the dual-
circuit brake system has failed. Drive, in such cases, to the nearest specialist garage without delay in order to have the problem rectified. Drive at a reduced speed while on your way to the dealer and adapt your style of driving to the higher brake pedal pressure required. Low brake fluid level An insufficient level of brake fluid may result in problems in the brake system. The level of the brake fluid is monitored electronically
⇒page 34, “Brake system
”.
WARNING
•
Only apply the brakes for the purpose of drying and cleaning the brake
discs if the traffic conditions permit this. Do not place any other road users in jeopardy.
•
When retrospectively mounting a front
spoiler, solid wheel hubs etc. one
must ensure that the air supply to the front wheel brakes is not reduced otherwise the braking sy
stem could run too hot.
•
Allow for the fact that new brake pads
do not achieve th
eir full braking
efficiency until approximately 200 kilo
metres. New brake pads must be first
“run in” before they develop their optimal friction force. You can, however, compensate for this slightly reduced
braking force by increasing the pres-
sure on the brake pedal. This guidelin
e also applies to any new brake pads
installed at a future date.
Caution
•
Never allow the brakes to ru
b by applying slig
ht pressure if you do not wish to
brake the vehicle. This causes the brakes to overheat and can also result in a longer braking distance and excessive wear.•
Before negotiating a steep downhill section, reduce your speed, shift down into
the next lower gear. This enables you to make full use of the braking power of the vehicle and reduces the strain on the brakes
. Any additional braking should be done
intermittently, not continuously.Brake boosterThe brake booster boosts the pressure which you generate with the brake pedal. The necessary pressure is only gene
rated when the engine is running.
WARNING
•
Never switch off the engine befo
re the vehicle is stationary.
•
The brake booster only operates when
the engine is running. Greater
physical effort for braking is required
when engine is swit
ched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.

Driving and the Environment
140
Avoiding full throttle Driving more slowly means saving fuel.Sensitive use of the accelera
tor will not only significantly reduce fuel consumption
but also positively influence environmen
tal pollution and wear of your vehicle.
You should avoid exploiting the top speed
of your vehicle wherever possible. Fuel
consumption, pollutant emissi
ons and vehicle noises increase disproportionally at
high speeds. The
⇒fig. 142
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 length
y red phase. Even after just 30 - 40 seconds
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 em
issions, 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 re
volutions at this time, however.
Regular servicing A poorly tuned engine consumes an unnecessarily high amount of fuel.Having your vehicle serviced regularly at a specialist garge enables you to satisfy one
of the requirements for economical moto
ring even before you set off on your
journey. Keeping your vehicle properly servic
ed not only has a positive effect on the
safety of your vehicle and maintaining its value, but also saves on
fuel
.
A poorly tuned engine can result in a fu
el consumption which is 10% higher than
normal. The foreseen maintenance work should be undertaken exactly according to the Service schedule by a specialist garage. Also check the
oil level
after refueling.
Oil consumption
is dependent to a consid-
erable extent on the load and speed of
the engine. Oil consum
ption could be as
high as 0.5 litres/1 000 km depending on your style of driving. It is quite normal that a new engine ha
s a higher oil consumption at first, and
reaches its lowest level only
after a certain running in
time. It is therefore not
possible to correctly assess the oil cons
umption of a new vehicle until after you
have driven about 5 000 km.
For the sake of the environment
•
You can achieve additional improvements
in your fuel economy by using high-
lubricity oils.•
Check the ground below your vehicle at re
gular intervals to detect any leakages
in good time. Please have yo
ur vehicle inspected by a specialist garge if you find any
stains caused by oil or
other fluids on the floor.
