@ Tips
The illumina tion for the instr ument cluster
lights up whenever you switch on the igni­
tion with the
vehicle headlights off. As
the daylight fades, the instrument cluster illumination likewise dims automatically
and will go out completely when the out­
side light is very low. This feature is meant
to remind you to switch on the headlights
when outside light condit ions become
poor.
Engine coolant temperature gauge
The engine coolant gauge q page 10, fig. 3 CD
only works when the ignition is on. To prevent
damage to your engine, please note the fol­
lowing important po ints:
Engine cold
As long as the needle remains at or close to
the bottom of the gauge, the engine still has
not reached its operating temperature. Avoid
high engine speeds, heavy engine loads and
heavy throttle applicat ions .
Normal temperature
When the engine has reached its operating
temperature, the needle will move into the
middle of the gauge and remain there. If the
engine is working hard at high outside tem­
peratures, the needle may rise up. This is no
need to worry as long as the. warning light
in the instrument cluster does not illuminate.
Warning light in the instrument cluster
When the. warn ing light in the instrument
cluster starts to flash, th is can mean one of
two things: either the coolant
temperature is .,..

Instrument s and warning /indicator lights 11
too high, or the coolant level is too low
¢ page 32.
If the needle is well in the upper area of the
ga uge , the coolant temperature is too high.
Stop the vehicle , switch the eng ine off and
allow the engine to cool.
If the warning light
comes on again after driving a short distance,
contact an authorized dealer.
A WARNING
-Always observe the warning in
¢ page 248, Engine compartment, be ­
fore opening the hood and checking the
engine coolant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yo urself. Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant.
(D Note
- Mounting additional lights or accessories
i n front of the air inlets reduces the cool­
in g effect of the rad iato r. At high outside
temperatures or high engine load, the
engine could overheat.
- The front spoi ler has been designed to
properly distribute the cooling air when
the vehicle is moving. If the spoiler is
damaged, this cou ld red uce the cooling
effect and the engine could then over­
heat. Ask your authorized Aud i dealer for
assistance .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes) .
The tachometer @¢ page 10, fig. 3 is the left
of the two large clock-type displays.
The engine turns at a speed
1,000 times the
single digit in the display, e.g . if the needle is
pointing at the "2" the engine is turning at
2,000 RPM. If
eng ine RPM drops below 1,500, you should
downshift to the next lower gear. The red area
at the end of the scale indicates maximum
permissible engine RPM after the break -in pe­
riod. Before reaching this area, move these­
lector lever to position "D (Drive)" or ease
your foot off the accelerator pedal.
Q) Note
The tachometer needle should not move
i nto the red range. If it does, then only for
a very short per iod of t i me. You could
damage your engine by driving at high
RPM .
@ For the sake of the environment
Upsh ifting early saves fuel and reduces en­
gine noise .
Digital clock with date display
Date and time of day can be set in the MMI.
Fig. 4 Instrument cluster w ith digita l clock
The date, time of day, and time and date for­
mat ca n be set in the MMI. You can find out

the driver's door is opened.
- When the ignition is turned off, the od­
ometer reading and the digital clock w ith
date display can be switched on for
about 30 seconds by pressing the
! CHECK I button c> page 12, fig . 6.

12 Instruments and warning/indicator lights
Speedometer with odometer

0 Adaptive Air Suspension
Applies to vehicles: with Adaptive Air Suspension
This II warning/indicator light has the fol­
l owing functions:
- It illuminates for a few seconds after the ig­
nition is turned on as function check and
then goes out .
- If the warning/ind icator light illuminates or
blinks continuously, there is a system fau lt
in the Adaptive A ir Suspension . A system
fault can result in limited ride comfort and
low ground clearance . Drive safely to the
nearest authorized Aud i dealer or qualified
workshop, and have the fault corrected .
- If the warning/ind icator light flashes, you
should not drive the vehicle. The flash ing
warning/ind icator light po ints to an extreme
High level. A very
pronounced lifting of the
vehicle (extreme High level) can resu lt, fo r
example, when a heavy load is removed
from the vehicle. As soon as the leve l has re­
turned to normal, the warning/indicator
light stops flashing, and you can drive away.
- If the warning/ind icator light flashes in con­
junction with the
II warning/indicator
light, you sho uld not drive off immediately
i n order to prevent damage to the under­
body. The two warning/ind icator lights flashing together points to an extreme Low
level. A very
pronounced lowering of the ve­
hicle (extreme Low leve l) can result, for ex­
ample, from a heavy load. As soon as the
level has retu rned to normal, the warning/
ind icator lights stop flashing, and you can
drive away.
(D Note
If the warning/indicator light flashes in
conjunction with the
II warni ng/indica­
tor light, you should not dr ive the veh icle
because low-lying vehicle parts can bot­
tom out as you drive over uneven ground
and be damaged as a result.
~ Adaptive Air Suspension
