shown by red and yellow lighted symbols and reminders to the driver
in the display.
Th e d river is also shown information about radio and CD operat ion
and directions for the navigation system. You can find additional

Memories
The trip computer is equipped with two fully automatic
memories as well as an efficiency program*.
Fig. 16 Trip computer
display: memory level
1
You can switch between the trip computer 1 and 2 and the efficiency
program* by pressing the [
RESET] button®=> fig. 17.
You can tell which memory level is currently active by the number or
the sign in the display=> fig. 16. The data from the single-trip
memory (memory level 1) is being displayed if a 1 appears in the
display . If a
2 is shown, then the data from the total-trip memory is
being displayed (memory level 2). The fuel pump nozzle
ii indicates
the efficiency program*=>
page 28.
Single-trip memory (Trip computer 1)
The single-trip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the trip is continued
within 2 hours from the time the ignition was turned off, the new
data will be included in the calculation of the current trip informa
tion. If the trip is interrupted for
more than 2 hours the memory is
reset automatically.
Total-trip memory (Trip computer 2)
Unlike the single-trip memory, the total-trip memory is not reset
automatically. This permits you to evaluate your driving data for the
entire period between manual resets.

& WARNING
Following other v ehicles too clo sely increases the risk of a crash
and serious per sonal injury.
• Following other vehicles too closely, particularly at higher
speeds in crea ses the ri sk of collisions and seriou s personal injury.
• Setting short distances to the traffic ahe ad reduces the time
and distance avail able to bring your vehicl e to a safe stop and
makes it even more necessary to pay close attent io n to t raffic.
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the pre vailing traffic, road , weathe r and
lighting conditions.
• Never rely on the distance control feature of ACC alone to
prevent rear-end collisions . Always be pr epared to brake and take
evasive action to a void collisions and other accident situations.
• Never allow the closing sp eed b etween you and other vehicles
to be so high that the Adapti ve Cruise Control may not be able to
s low your vehicle safely . If closing speed is too high, you must
apply the brakes yourself to reduce the r isk of a rear -end crash.
• Always select a greater following di stance to the vehicle ahead
on wet roads than on dry roads.
• Always read and h eed the information and WARNINGS=>

"Description" on page 136.

The distance setting is reset to the factory de fault DIS TANCE 3 the

While the vehicle is being raised or lowered, the target level is indi
cated by an arrow © next to the corresponding segment. The arrow
disappears again when the vehicle is at the target level.
Limitations to MMI settings
Please note that not every driving mode can be selected in every
dr iving s ituation . For example , it is not poss ible to switch to "lift"
mode at speeds above 12 mph (20 km/h) . This mode is then shown
greyed out in the MMI Display .
The vehicle can on ly be lowered when
all of the veh icle's doors are
closed.
If one doo r is open, all driving modes whose level setting is
below the current vehicle level appear greyed out in the MMI Display.
If a door is opened whi le the vehicle is being lowered , the lowering
process is interrupted until all doo rs are closed again.
I f the system is temporarily unavailable due to, for instance, an
empty compressed air tank, the driving modes that cannot be set
appear
greyed out in the MMI Display . As soon as the system is avail
able aga in, the driv ing modes can once more be selected in the
display .
(I] Tips
• For additional information on the driving modes=> page 179,
"Chassis controls".
• When the compressed air tank is empty , the compressor can be
switched on by starting the engine. The Adaptive Air Suspension is
once again available, after waiting a few minutes.
• T o prevent overload, the system switches off temporarily if
severa l adjustments are made in a row. The Adaptive A ir Suspens ion
is once again available, afte r waiting a few minutes. •
