Use temperature control rocker
switches4 and6 to separately adjust
the air temperature on each side of the
rear passenger compartment.
You should raise or lower the temperature
setting in small increments, preferably
starting at 72°F (22°C). The adjusted tem-
perature appears in the display5. The
rear climate control will adjust to the set
temperature as fast as possible.1Temperature, left

vent. The air temperature is about the
same as that of the dashboard air vents.
The lever is located in the front center
vent.

speed.

Briefly lift1 or depress2 the cruise
control lever.
The current speed is set.

pedal.
Cruise control is activated.
The selected speed appears in the multi-
function display for approximately
5 seconds, and the corresponding speed-
ometer segments from the selected speed
to the vehicle maximum speed are illumi-
nated.
Warning!
G
The cruise control brakes automatically so
that the set speed is not exceeded.
Keep in mind that the cruise control is a con-
venience system designed to assist the driv-
er during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
i
On uphill or downhill grades, the cruise con-
trol may not be able to maintain the set speed.
Once the grade eases, the set speed will be re-
sumed.
On downhill grades, the cruise control maintains
the set speed with active braking action. In addi-
tion, on longer downhill grades the automatic
transmission will automatically downshift.

Canceling cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.
The cruise control is canceled. The last
speed set is stored for later use.
or

Briefly push the cruise control lever in
direction of arrow3 (
page 216).
The cruise control is canceled. The last
speed set is stored for later use.Setting a higher speed

Lift the cruise control lever in direction
of arrow1 (
page 216) and hold it
up until the desired speed is reached.

Release the cruise control lever.
The new speed is set.
Setting a lower speed

Depress the cruise control lever in
direction of arrow2 (

!
Moving the gear selector lever to positionN
while driving also cancels the cruise control.
However, the gear selector lever should not be
moved to positionN while driving except to
coast when the vehicle is in danger of skidding
(e.g. on icy roads).
i
Depressing the accelerator pedal does not
deactivate the cruise control. After brief acceler-
ation (e.g. for passing), the cruise control will re-
sume the last speed set.
i
When you use the cruise control lever to de-
celerate, the brake system will automatically
brake the vehicle if the engine’s braking power
does not brake the vehicle sufficiently.

ometer segments from the selected speed

Distronic*
When activated, the Distronic adaptive
cruise control system increases driving
convenience afforded by the cruise control
during travel on expressways and other
major roads.

If the Distronic distance sensor detects
a slower moving vehicle directly ahead,
your vehicle speed will be reduced so
that you follow that vehicle at a preset
distance.


If there is no vehicle directly ahead of
you, Distronic will function in the same
way as cruise control (
page 216).
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.
Warning!
G
Distronic adaptive cruise control is no sub-
stitute for active driving involvement. It does
not react to stationary objects, nor recog-
nize or predict the curvature and lane layout
or the movement of vehicles ahead.
Distronic can only apply a maximum of 20%
of the vehicle’s braking power.

If Distronic detects a vehicle directly
ahead, the segments (representing the
difference) from the speed of the vehicle
ahead to the set speed come on.
If Distronic calculates that there is a dan-
ger of collision:

instrument cluster comes on red.


An intermittent warning sounds.
Distronic is designed and intended only to
maintain a set speed and keep a set dis-

The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.
i
The vehicle speed displayed on the speed-
ometer can briefly vary from the speed setting
on the Distronic system.
