cruise control will resume speed regulation back
to the stored speed.
Cruise control is operated using the correspond‐
ing steering wheel buttons. You can store any
speed above 15 mph (20 km/h) up to the maxi‐
mum speed.
If you fail to adapt your driving style, cruise con‐
trol can neither reduce the risk of an accident
nor override the laws of physics. It cannot take
into account road, weather or traffic conditions.
Cruise control is only an aid. The driver is
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time
and for staying in lane.
Mercedes‑AMG vehicles: Cruise control is
available up to a maximum speed of 155 mph
(250 km/h).

System limits
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle. By
Driving and parking 183
doing so, you will make use of the engine's brak‐
ing effect. This relieves the load on the brake
system and prevents the brakes from overheat‐
ing and wearing too quickly.
Do not use cruise control in the following situa‐
tions:
In traffic situations which require frequent
R
changes of speed, e.g. in heavy traffic, on
winding roads.
On slippery roads. Accelerating can cause
R
the drive wheels to lose traction and the
vehicle could then skid.
If you are driving when visibility is poor.

& WARNING Risk of accident due to stored
speed
If you call up the stored speed and this is
lower than your current speed, the vehicle

before calling up the stored speed.
