Cruise control
Driving convenience system for auto-
matically maintaining the vehicle speed 
set by the driver.Distronic*
A driving convenience cruise control 
system which helps the driver maintain 
a pre-selected speed:
If there is no vehicle directly ahead, 
the system operates in the same 
way as conventional ->cruise con-

If a slower moving vehicle is ahead, 
Distronic will reduce your vehicle 
speed to the extent permitted by re-
duced throttle and up to 20% brak-
