Driving Systems; Activation Conditions - Mercedes-Benz 2016 GL Operator's Manual

select a lower gear in good time on long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer. By doing
so, you will make use of the braking effect of
the engine. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
i
Cruise control should not be activated
when driving off-road.
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time and for staying in
your lane.
Do not use cruise control:
in road and traffic conditions which do not
R
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
on slippery road surfaces. Braking or accel-
R
erating could cause the drive wheels to lose
traction and the vehicle could then skid
when there is poor visibility, e.g. due to fog,
R
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.
