Electro-mechanical parking brake

This warning lamp monitors the electro-mechanical
parking brake.The warning lamp
 lights up when the parking brake is applied
with the ignition on. After the ig nition has been switched off the
lamp will stay on for about 30 seconds. The warning lamp will light
up for about 30 seconds if the parking brake is applied with the igni-
tion switched off.
The warning lamp should go out wh en the parking brake is released.
If the warning lamp flashes continuously after the parking brake has
been applied , the brake may not be strong enough to hold the
vehicle on a slope. This may be due to the brakes overheating.
Please note the following points:
•
If the gradient is too steep to park the vehicle safely, the display
will show the message Caution: Vehicle parked too steep .
•
In the event of a fault in the parking brake system the symbol

will also appear in the instrument cluster display together with the
message Parki ng b rake! You should have the fault corrected by a
qualified workshop without delay.
Brake system

The warning lamp flashes if the brake fluid level is too low
or if there is a fault in the ABS system or the parking
brake.If the warning lamp
 flashes, there is a fault in the brake system.
The symbol
 in the instrument cluster display will flash at the
same time. You can press the button to obtain a message
explaining the fault ⇒page 31 .
If a failure should occur in the ABS, the ABS warning lamp
 will
light up together with the brake warning lamp
 ⇒ .
WARNING
•
Before opening the bonnet and ch ecking the brake fluid level,
observe the warning information on ⇒page 231, “Working on
components in the engine compartment”.
•
If the brake warning lamp does not go out, or if it lights up
when driving, the brake fluid level in the reservoir is too low – this
may cause an increased accident ri sk. Stop the vehicle and do not
drive on. You should obtain professional assistance.
•
If the brake warning lamp lights up together with the ABS
warning lamp, this can mean that the control function of the ABS
is out of action. As a result the rear wheels can lock relatively
easily when braking. This could caus e the tail of the vehicle to skid
sideways. Drive carefully to the nearest qualified workshop and
have the fault rectified.
Fuel gaugeThe gauge only works when the ignition is switched on.
When the needle reaches the reserve zone, the symbol
 lights up
in the instrument cluster display ⇒page 36 together with the
message Please refuel . At this point there are still about 8 litres of
fuel left in the tank. This is your reminder to fill up soon.
The tank capacity of your vehicle is given in the Technical data
section ⇒page 293 .
Caution
Never run the tank completely dry. If there is an irregular fuel supply,
misfiring can occur. This allows unburnt fuel to enter the exhaust
system, which could cause overheating and damage the catalytic
converter.

Technical data
CD and radio displayIf no priority 1 or 2 faults have been detected by the auto-check
control, the name or frequency of the current radio station and the
selected waveband will appear the upper part of the display.
When a CD is playing, the display will show the current title. If the
vehicle is equipped with a CD changer* the display will also show
the number of the CD being played (CD1 to CD6).Outside temperature display
The outside temperature is shown when the display is
activated.
At temperatures below +5°C a snow flake symbol appears next to the
temperature display. This is to warn the driver to take extra care
when there is a risk of ice on the road.
When the vehicle is stationary or travelling at very low speeds, the
temperature displayed may be slightly higher than the actual
outside temperature as a result of the heat radiated from the
engine.
The temperature units can be set to °F or °C on the MMI* or sound
system control console. The outside temperature is automatically
displayed in the units you have selected. Please refer to the Oper-
ating Manual for the MMI* or sound system.
WARNING
Do not rely on the outside temper ature display as an ice warning.
Please bear in mind that there may be patches of ice on the roads
even at outside temperatures around +5°C.Applies to vehicles: with manual gearbox and gear-change indicatorGear-change indicator
This additional indicator fu nction can help to save fuel.

Driver information system
24
– The remaining time and distance to the next service are indicated every time the ignition is switched on, until the
service becomes due.
Service due
–When a service is due, Service! will appear in the display as soon as you switch on the ignition. The display reverts
back to the standard display after about 5 seconds.
Displaying the service interval
– Select: Function selector button > Service interval
display ⇒ page 23, fig. 15.
Resetting the oil change interval display
– Select: Function selector button > Service interval
display > Reset oil change interval .Displaying distance to next service
You can have the distance to the next service displayed on the MMI
screen ⇒page 23, fig. 15. The remaining distance to the next
service is updated every time the ignition is switched on (starting at
500 km after a service has been performed).
On a new vehicle, the display wi ll always show the following
message for the first 500 km.
SERVICE IN ----- KM --- DAYS
Caution
The system cannot calculate the figures for the service indicator if
the battery is disconnected from the vehicle, so no service reminder
can be displayed during this time. Please remember that keeping to
the correct service intervals is most important for the service life
and residual value of the vehicle (and especially for the life of the
engine). The period between two services must never be longer than the time specified in the Service Schedule, even if you only
cover a low mileage during this time.
Note
•
Do not reset the display between oil changes - otherwise the
display will be incorrect.
•
The information in the service interval display remains intact if
the battery is disconnected.
•
The distance to the next service cannot be called up if the system
has detected a Priority 1 fault (red symbol).
•
If the service was not performed by a qualified workshop, the oil
change interval display can only be set to “fixed service intervals” of
15,000 km. If you wish to continue with the “LongLife” service, you
will need to have the oil change interval display reset by a qualified
workshop.

The message will disappear from the display after about 5 seconds.
If required, the message can be called up again by briefly pressing
the button ⇒fig. 24.
Driver messages and yellow symbols

 in the instrument cluster will start flashing as
well if there is a fault in the brake system.
Fault in the cooling system

Faults in the cooling system must be rectified immedi-
ately.If the
 symbol flashes in the display, this means that
either the coolant temperature is too high or the coolant
