RangeThe estimated range in kilometres is shown on the display. It indicates the distance you
can still drive with your vehicle based on th e present level of fuel in the tank for the
same style of driving.
The readout is shown in steps of 10 km. After lighting up of the indicator light for the
fuel reserve the display is shown in steps of 5 km.
The fuel consumption for the last 50 km is taken as a basis for calculating the range. If
you drive in a more economical manner fr om this moment on, the range will be
increased accordingly.
If the memory is set to zero (after disconnecting the battery), th e fuel consumption of
10 ltr./100 km is calculated for the range; afterwards the value is adapted accordingly
to the style of driving.Distance drivenThe distance driven since the memory was last erased appears in the display
page 20. If you wish to measure the distance driven of a particular time, you must
set the memory to zero at this moment in time by pressing the button page 21,
fig. 19 on the windshield wiper leve r or the handwheel on the page 21, fig. 19
multifunction steering wheel*.
The maximum distance indicated in both memo ries is 1 999 km or on vehicles with
information display*, it is 9 999 km. The indicator is set back to null if this period is
exceeded.Average speedThe average speed since the memory was last erased is shown in the display in
km/hour page 20. If you wish to determine the average vehicle speed over a certain
period of time, you must set the memory to zero at the start of the measurement using
the button page 21, fig. 19 on the windshield wiper lever or with the handwheel
page 21, fig. 19 on the multifunction steering wheel*.
A zero appears in the display for the first 100 m you drive after erasing the memory.
The indicated value will be updated every 5 seconds while you are driving.
Current speed*The current speed which is identical to the display of the speedometer page 16,
fig. 15 is indicated on the display.Oil temperature*The oil temperature appears in the display when the ignition is switched on. If the oil
temperature is lower than 50°C or if a fault in the system for checking the oil tempera-
ture is present, three lines are displayed instead of the oil temperature.Warning against excessive speeds*This function enables you to set a speed limit, e.g. if you drive in town. A text in the
display is intended to draw your attention to the fact that you have exceeded the set
speed limit.Warning against excessive speedsYou can set the desired speed limit as follows:
– Select the menu point Speed warning --- km/h (warning at --- km/h). .
– Drive e.°g at a speed of 50 km/h.
– Press the button page 21, fig. 19 on the windshield wiper lever or the hand-
wheel page 21, fig. 19 on the multifunction steering wheel*. Speed warning
50 km/h (warning at 50 km/h) is displayed in the information display*. You can
increase or reduce this value with the button on the windshield wiper lever or
by turning the handwheel on the multifunction steering wheel*.
– The value is stored by repeated pressing of the button on the windshield wiper lever or the handwheel on the multifunction steering wheel*.
If you now exceed the set speed limit, Speed 50 km/h exceeded will be shown in the
display. This message is indicated for as long as the speed is reduced below the set
limit or switch off the message by pressing the button page 21, fig. 19 on the
windshield wiper lever or the handwheel page 21, fig. 19 on the multifunction

WARNING
If you do not pay attention to the warning lights coming on and the corre-
sponding descriptions and warning notes, this may result in severe body inju-
ries or major vehicle damage.
The engine compartment of your car is a hazardous area. There is a risk of
injuries, scalding, accidents and fire wh en working in the engine compartment,
e.g. inspecting and replenishing oil and other fluids. It is also essential to
observe all warnings page 204, “Working in the engine compartment”.Note
The arrangement of the indicator lights depends on the model version. The
symbols shown in the following functional description are to be found as indicator
lights in the instrument cluster.
Operational faults are shown in the instrument 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.

Stop the vehicle and switch the engine off if the warning light does not go off after
the engine has started or flashes while driving. Check the oil level and top up with oil
as necessary page 205.
3 peeps sound as an additional warning signal.
Do not continue your journey if for some reason it is not possible under the condi-
tions prevailing to top up with oil. Keep the engine switched off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe engine
damage.
Do not drive any further if the warning light flashes even if the oil is at the correct
level. Do not run the engine not at idling speed either. Contact the nearest specialist
garage to obtain professional assistance.
The following text will be displayed in the information display*:
Oil Pressure: Engine off! Owner's manual!
The warning light

Active driver-steering recommendation (DSR)*Vehicles with ESP and ABS are equipped with active driver-steering recommendation
(DSR).
This function indicates to the driver in critical situations a steering recommendation in
order to stabilise the vehicle. The active driver-steering recommendation is activated,
for example, on the right and left vehicle si de when braking sharply on different road
surfaces.
WARNING
Even with this function the vehicle canno t steer itself! The driver is furthermore
responsible for the steering of the vehicle!BrakesWhat has a negative effect on braking efficiency?Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions of
the vehicle and your style of driving. Particul arly if you drive a great deal in towns and
over short distances or if you adopt a sporty style of driving, it may be necessary to
have the thickness of the brake pads inspected at a specialist garage between the
service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain conditions
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 coatin g of ice on them in winter. Yo u s h o u l d d r y t h e b r a k e s a s
soon as possible 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 with road salt if you have not used the brakes
for some considerable time beforehand. The layer of salt on the brake discs and brake
pads must first be rubbed off when you apply the brakes. Corrosion
Corrosion on the brake discs and dirt on the 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 firm ly applying the brakes at a fairly high
speed if you do not make much use of the braking system or if surface corrosion 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 possib le 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 rectifie d. 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 36, “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 jeop-
ardy.
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 other-
wise the braking system could run too hot.
Allow for the fact that new brake pads do not achieve their full braking effi-
ciency until approximately 200 kilometres. New brake pads must be first “run
in” before they develop their optimal fric tion force. You can, however, compen-
sate for this slightly reduced braking fo rce by increasing the pressure on the
brake pedal. This guideline also applie s to any new brake pads installed at a
future date.

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 seconds you
will have saved more fuel th an 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 emis sions, 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 revolu tions 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 motoring even before you set off on your journey.
Keeping your vehicle properly serviced not on ly 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 consider-
able extent on the load and speed of the en gine. Oil consumption 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 has 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 consumption 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 regular intervals to detect any leakages in
good time. Please have your vehicle inspec ted by a specialist garge if you find any
stains caused by oil or other fluids on the floor.
Avoid driving short distances
Short distances result in an above-average high fuel consumption.– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter mu st first have reached their optimal operating
temperature in order to effectively reduce fuel consumption and pollutant emissions.
The cold engine vehicle cons umes approx. 15 - 20 litres/100 km of fuel immediately
after starting. Fuel co nsumption drops to 10 litres/100 km after just 1 kilometre. The
engine reaches its operating temperat ure (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then stabi-
lizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature fig. 153 . It
shows the fuel consumption af ter driving a certain distance, on the one hand at a
temperature of +20°C and on the other hand at a temperature of -10°C. Your vehicle
has a higher fuel consumptio n in winter than in summer.

Technical Data
Avoiding damage to your vehicleWhen driving on poor roads and lanes or when driving over kerbstones, steep ramps
etc., you must pay particular attention to ensuring that any low-slung parts of the
vehicle, such as spoiler and exhaust, do not touch the ground and get damaged.
This particularly applies to models with a lowered suspen sion (sport suspension) and
also when your vehicle is fully laden.Driving through bodies of water on roadsIn order to avoid damage to the vehicle wh en driving through bodies of water (e.g.
flooded roads), observe the following:
Determine the depth of the water when driv ing through bodies of water. The water
can reach at the maximum the web on the lower sill of the vehicle fig. 154 .
Drive no more than at walking speed. At a higher speed, a water wave can form in
front of the vehicle which can cause water to penetrate into the air induction system of
the engine or into other parts of the vehicle.
Never let the vehicle stand in the water, never drive backwards and do not switch
off the engine.
WARNING
Driving through water, mud, sludge etc. can reduce the braking power and
extend the braking distance - risk of accident!
Avoid sudden and severe braking manoeuvres immediately after driving
through bodies of water.
After driving through bodies of water, the brakes must be cleaned and dried
as soon as possible by intermittent braking. 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.Caution
When driving through bodies of water, pa rts of the vehicle such as the engine,
gearbox, catalytic converter, chassis or electrics can be severely damaged.
Oncoming vehicles can generate water waves which ca n exceed the permissible
water level for your vehicle.
Potholes, mud or rocks can be hidden under the water making it difficult or impos-
sible to drive through the body of water.
Do not drive through salt water. The salt can lead to corrosion. Immediately rinse
all the parts of the vehicle, which came into contact with the salt water, with fresh
water.Note
After driving through a body of water, we recommend that the vehicle is checked by a
specialist garage.Off-road drivingImportant information
WARNING
Never drive too fast, particularly not around curves, and never undertake
extreme driving manoeuvres.
Always adjust your speed and adapt your style of driving to suit road, off-
road, traffic and weather conditions.
