damage.
• Whenever stalled or stopped for repair, move the vehicle a safe
distance off the road, stop the engine, and turn on the emergency

Adaptive Air Suspension c.::i
The c.::i symbol illuminates for a few seconds after you have
switched on the ignition to indicate
redu ced ground clea ranc e when
the dynamic mode is activated and when the ignition is switched on
with a vehicle which was parked in dynamic
mode ~ page 186,
"Chassis Controls" . On vehicles which are equipped with the s port
s u spen sio n
Adapt ive Air Suspension -Spor t*, the check light does
not come on in this instance since ground clearance is general ly
reduced.
This warning/indicator light has the following functions:
• It illuminates for a few seconds after the ignition is turned on as
function check and then goes out .
• If the warning/indicator light flashes in conjunction with the
<::'.p
warning/ indicator l ight, you should not drive the veh icle immedi­
ate ly in order to prevent damage to the underbody . The two
warning/indicator lights flash ing toget her po ints to an extreme Low
level. A very
pronounced lowering of the vehicle (extreme Low level)
can resu lt, for example, from a heavy load. As soon as t he level has
returned to normal, the warning/ind icator lights stop flashing, and
you can drive away .
0 Note
If the warning/indicator light flashes in conjunction with the~
warning/ indicator l ight, you should not drive the veh icle because
low -lying vehicle parts can bottom out as you drive over uneven
ground and be damaged as a resu lt .•

Memories
The trip computer is equipped with two fully automatic
memories.
Fig . 22 Trip computer
display: memory level 1
You can switch between the trip computer 1 and 2 by pressing the
Reset button
@ =>fig. 23.
You can tell which memory level is currently active by the number in
the
display => fig. 22. The data from the single -trip memory
(memory level 1) is being displayed if a
1 appears. If a 2 is shown,
then the data from the total -trip memory is being displayed
(memory level 2).
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 .•

ment

turned the ignition off will be displayed.
In addition to the trip computer information (memory level 1 or 2) ,
navigation information and Adaptive Cruise Control * information
can be displayed . To switch the display between the different
systems, tap the Reset button

switched on. You are always responsible for your speed and the
distance between your vehicle and other vehicles.
• For safety reasons, the cruise control should not be used in the
city, in stop-and-go traffic, on twisting roads and when road condi­
tions are poor (such as ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident.
• Turn off the cruise control temporarily when entering turn
lanes, highway exit lanes or in construction zones.

&, WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake . This is because
the cruise control is overridden by the driver's acceleration.
[ i] Tips
The brake lights illumin ate as soon as the brakes decelerate
automatically. •
Changing speed
-Press lever@in the 0 or Q direction=> page 137,
fig. 149 to increase or decrease your speed.

Change speed in increments of 1 mph (1 km/h) by lightly pressing
the lever . If you keep the lever pressed down, you will alter your
speed in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your
speed, e.g. if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.
The green symbol in the
display=> page 137, fig . 150 is replaced
with a white symbol. The saved speed remains the same. •
Presetting your speed
You can preset your desired speed while the vehicle is not
moving.
-Turn on the ignition .
-Pull lever@ into position G) => page 137, fig. 149 .
-Press the lever in the 0 or Q direction to increase or
decrease your speed.
-Release the lever to save that speed.
This function makes it possible, for example, to save the speed you
want before driving on the highway. Once on the highway, activate
the cruise contro l by pulling the lever toward

-Switch the ignition off.
The system retains the saved speed if you deactivate the cruise
control temporarily . To resume the saved speed , release the brake
