The instrument cluster gives the driver basic information such as the current
speed, engine speed, the state of some vehicle systems and the like.
Fault display
If there is a fault in the instrument cluster, the Error message will appear in
the display.
Seek help from a specialist garage.
WARNINGConcentrate fully at all times on your driving! As the driver you are fully re-
sponsible for road safety.
Note
When the ignition is on, the instrument cluster is illuminated 1)
. The brightness
level is automatically adjusted depending on the ambient lighting.OverviewFig. 20

The tachometer
1
» Fig. 20 on page 30 or » Fig. 21 on page 30 shows the ac-
tual engine speed per minute.
The beginning of the red scale range of the tachometer indicates the maxi-
mum permitted engine speed of a driven-in and operating warm engine.
You should shift into the next highest gear before the red scale of the revolu- tion counter is reached, or select mode D on the automatic gearbox.
The gear recommendation is important to note in order to maintain the opti-
mum engine speed » page 43.
CAUTION
The pointer of the tachometer must reach the red area for only a short time -
there is a risk of engine damage!34567DisplayFig. 22

Warning at excessive speeds
An audible warning signal will sound when the vehicle speed exceeds 120 km/
h 1)
. The audible warning signal is switched off when the vehicle speed falls be-
low 120 km/h.
Coolant temperature gauge
Fig. 23
Coolant temperature gauge
Read and observe on page 30 first.
Applies to cars with the instrument cluster - Version 1 » Fig. 20 on page 30 .
The display » Fig. 23 provides information on the engine coolant temperature.
The display only works if the ignition is switched on.
In vehicles with the instrument cluster - version 2, » Fig. 21 on page 30 the
coolant temperature is indicated only by one of the warning lights » page 36,
Coolant
coming on or going off.
Cold range
If the pointer is still in the left area of the scale, this indicates that the engine
has not yet reached its operating temperature. Avoid high speeds, full throttle
and high engine loads. This prevents possible damage to the engine.
The operating range
The engine has reached its operating temperature as soon as the pointer
moves into the middle of the scale
A
» Fig. 23 . At very high ambient tempera-
tures or heavy engine loads, the pointer may move even further to the right.
High temperature range
If the pointer reaches the red area of the scale, the coolant temperature is too
high. Further information » page 36,
Coolant
.
CAUTION■
Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
Never cover the radiator - there is a risk of the engine overheating.
Fuel gauge

Display in the instrument cluster - Version 1
In the display of the instrument cluster - Version 2
The display only works if the ignition is switched on.
The fuel tank has a capacity of about 55 litres.
The warning light lights up when the amount of fuel reaches the reserve
zone
» page 39 .
The reserve zone is indicated by the red area of the scale » Fig. 24 -
or by
displaying only the last two segments of the scale » Fig. 24 -
in the magnify-
ing glass.

This function only applies to certain countries.
32Using the system
Some error messages and other information are displayed in the MAXI DOT
display. The messages are displayed simultaneously with the icons in the MAXI
DOT display or with the warning lights in the instrument cluster » page 34,
Indicator lights .
The menu item Vehicle status is shown in the main menu of the MAXI DOT
display whenever at least one fault message exists. After selecting this menu,
the first of the error messages is displayed.
If there are several error messages, the display will show 1/3, for example, be-
low the message. This indicates that the first of a total of three error messag-
es is being displayed.

engine oil sensor defective» page 36Problem with the engine oil pressure» page 34Clutches of the automatic DSG gearbox are
too hot» page 34
Problem with the engine oil pressure
If the symbol is shown in the MAXI DOT display, you must have your vehicle
checked immediately by a specialist garage. The information about the maxi-
mum permissible engine speed is displayed together with this symbol.
Clutches of the automatic DSG gearbox are too hot
A symbol in the MAXI DOT display indicates that the temperature of the au-
tomatic gearbox DSG clutches is too high.
The following message is shown in the MAXI DOT display. Gearbox overheated. Stop! Owner's manual!
do not continue to drive! Stop the vehicle, switch off the engine, and wait
until the icon goes out – risk of gearbox damage! You can continue your
journey as soon as the symbol disappears.
WARNINGIf you have to stop for technical reasons, then park the vehicle at a safe
distance from the traffic, switch off the engine and switch on the hazard
warning lights » page 62. The warning triangle must be set up at the pre-
scribed distance - observe the national legal provisions when doing so.
Note
■ If the MAXI DOT display shows warning messages, these messages must be
confirmed in order to access the main menu » page 42, Using the information
system .■
As long as the operational faults are not rectified, the symbols are always in-
dicated again. After they are displayed for the first time, the symbols continue
to be indicated without any extra messages for the driver.

36Using the system
WARNING■Carefully open the coolant expansion bottle. If the engine is hot, the cool-
ing system is pressurized – risk of scalding! It is therefore best to allow the
engine to cool down before removing the cap.■
Do not touch the radiator fan. The radiator fan may switch itself on auto-
matically even if the ignition is off - a danger of injury is present!
CAUTION
■ Additional headlights and other attached components in front of the air inlet
impair the cooling efficiency of the coolant.■
