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
following will assist in maintaining the set cruise
controlled speed:Vehicles with automatic transmission:
Downshift occurs (max. to 3rd gear) to maintain the set
cruise controlled 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.
Vehicles with manual transmission:
The set cruise controlled speed is switched off when
declutching exceeds four seconds during downshifting a
gear.
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.
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.
