The different symbols for the time intervals appear if you change the
settings ~ fig. 139 .
The text message ... (three white dots) appears if a setting cannot be implemented with the operating lever . The following are possible
reasons:
• If you pul l the control lever towards you to resume speed but no
requested speed was set .
• I f you push the lever up to increase (or down to reduce) speed
when no speed has been set previously.
• If you push the lever up to increase (or down to reduce) speed
and this speed is outside the range from 20 to 95 mph (Canada
models : 30 to 150 km/h) .
ACC fun cti ona lity limited
The text message AC C functionalit y limited appears when the ACC
System does not detect any objects over an extended time period.
For the time being, the distance to vehicles up ahead is not being
Con tro ls and eq uip­
ment
controlled. The ACC system is not switched off, so increased alert­
ness is required. The following may be reasons for the text message
ACC Functiona lly limited:
• The ACC sensor is dirty. The ACC system is not reacting, or is not
reacting correctly, to veh ic les travel ing ahead.
• I t is possible that you are driving on a road with very light traffic
without anything at the side of the road (e.g. guard rai ls, traffic
signs, trees). As soon as a vehicle is detected by the system again,
it returns to its control range and the text message disappears .
The ACC sensor is located in the area under the front license plate.
If there is a loss of operation due to heavy contamination, this area
should cleaned to restore proper operation .
ACC not available
The text message ACC n ot ava ila ble appears, for example, if the
t emperature of the brakes is excessive. Adap tive Cruise Control is
temporarily not available . A warning tone sounds as a reminder .
ACC not available!
The text message ACC not ava ilable ! appears in the event of a
malfunction . Adaptive Cruise Contro l is tur ned o ff. A warning to ne
sounds as a reminder. Have the system inspected by a qua lified
dea lership .
ACC se nsor bl ocked !
The text message AC C sensor blocked ! appears when the ACC
System can no longer guarantee safe detection of objects . Adaptive
cruise control is turned off. A chime sounds as a rem inder .
To decide whether it is necessary to switch off the ACC (ACC sensor
blocked
!) or if it is only a temporary condition (ACC functionality
limited), the system wi ll also takes into consideration the outside
temperature and/or the windshield wiper operation.
The ACC sensor is dirty o r blocked (e .g . leaves, sn ow).

In cer tain situati ons, the braking power of t he Adaptive cruise
control is not sufficient to maintain an adequate distance from the
object ahead. In this situation, the Adap tive cruise contro l ca lls on
you as the driver to take action.
The
driver intervent ion prompt a lerts you visual ly and audibly.

• An warning tone sounds .
[ i ] Tips
• I f the Adaptive cruise control initiates braking, the hydraul ic
brake system is under pressure. Therefore, the brake peda l distance
is shorter and the pedal "feels" harder.
• Adaptive Cruise C ontro l is switched off af ter pressing the foot -
brake. The speed
saved up this point can be resumed. _,,,

General information
Some driving situations which affect the function of the
radar sensor ore described below.
When driving, the Adaptive Cru ise Control is governed by physical
and system -specified limits. Also, under certain circumstances, the
ACC system may react unexpec tedly or late from the dr iver's point
of view. Therefore, always be attentive and intervene, if necessary :
• when driv ing around curves~
page 148
• when vehicles in front are not in line with your
vehic le ~
page 148
• when other vehicles are changing lanes~ page 149

Dynamic shift program (DSP)
The aut om atic tr a nsmission is ele ctr onically cont rolled.
T he transmission is self adapting and wi ll automati cally se lect the
b est shift program suited to the driving condi tions and drivi ng s tyle.
The transmission wil l se lect one of the
economy programs when
you drive at a steady speed or a gradually changing speed without heavy acceleration . This achieves optimum fuel efficiency, with ear ly
upshifting and delayed downshifting.
The trans missi on will au tomat ica lly select the
sporty shi ft prog rams
when you drive at higher speeds, or with heavy acce leration and
frequen tly cha nging speeds . Upshifts ar e delayed t o make full use
of engine power . Down shifting takes place at higher engine speeds

_______________________________________________ A_ u_t _o _m_ a_ t_ i_ c _ t_r _ a _n _s_ m_ i_ s _ s_ i_ o _ n _ ___._
The selection of the most suitable shift program is a continuous,
automatic process. The driver can also make the transmission
switch to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down to a lower gear to
achieve rapid acceleration, e.g. for quickly passing another vehicle.
You do not need to press the gas pedal into the kick -down range.
After the transmission has upshifted, the original program is
selected according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients .
This keeps the transmission from shifting up and down unneces ­
sarily on hills. The transmission will shift down to a lower gear when
the driver presses the brake pedal on a downhill gradient. This
makes use of the braking effect of the engine without the need to
shift down manually .•
