Cruise control
Import ants afety notes Cruise control maintain
saconstant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
shift to alower gear in good tim eorselect
shift range 1,2or 3on vehicles with auto-
matic transmission. By doing so, you will
mak euse of the brakin geffect of th eengine,
which relieves the load on the brake system and prevents the brakes from overheating
and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan
store any road spee dabove 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay atten tion to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for brakin gingood time. G
Risk of accident
Do not use cruise control:
R in road and traffic condition swhich do not
allow you to maintain aconstant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Brakin goraccelerating
coul dcause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
Cruise control lever You can operate cruise control and variable
