Notes:
If the engine does not brake the vehicle sufficiently
while driving on a downgrade, the speed you set on the
cruise control may be exceeded. In this case the
automatic transmission shifts down (max. to 3rd gear)
to maintain the set cruise control speed by using the
engine’s braking power.
As soon as the grade eases, the automatic transmission
shifts up again dependent on the selector lever position.
Nevertheless, in some cases you may have to step on the
brake pedal to slow down. In this case the cruise control
is switched off.
Use the lever to resume the previously set speed.
The “CRUISE CONTROL - - -” message is displayed on
the multifunction display when any attempt is made to
store speeds below 25 mph (40 km/h) or when an
attempt is made to recall a speed when no speed has
been stored – the cruise control remains switched off.
See malfunction and warning messages on page 297 if
the cruise control has a malfunction.
Wa r n i n g !
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.
• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.

(optional)
When activated the Distronic system increases driving
convenience, for example over long distances, as it
automatically maintains a speed set by the driver by
actively regulating the throttle setting. It also maintains
within certain limitations a preset distance to a vehicle
ahead.
With Distronic switched off, the multifunction display
continues to show the distance to the vehicle ahead, if
so selected, see page 266.
The distance notification function can be activated
separately, see page 264.
In Distronic mode, if the distance sensor detects a
slower moving vehicle directly ahead, your vehicle
speed will be reduced to the extent permitted by
reduced throttle and up to 20% of vehicle braking power,
so that you follow that vehicle at a preset distance, see
page 265.
Maximum range of detection is approximately 500 ft.
(150 m).Any given speed between 25 mph (Canada: 30 km/h)
and 110 mph (Canada: 180 km/h) can be maintained
with the Distronic by operating the control lever on the
steering column.
Wa r n i n g !
Distronic is a convenience system, its speed
adjustment reduction capability is intended to
make cruise control more effective and usable
when traffic speeds vary. It is not, however,
intended to nor does it replace the need for extreme
care. The responsibility for the vehicle speed and
the distance to the vehicle ahead, including most
importantly brake operation to assure safe stopping
distance, rests always with the driver.Wa r n i n g !
Distronic requires familiarity with its operational
characteristics. We strongly recommend that you
review the following information carefully before
operating the system.
