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 doing so, you
will make use of the engine's braking effect. This
relieves the load on the brake system and pre-
vents the brakes from overheating 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 the
R
drive wheels to lose traction and the vehicle
could then skid.

▌Function of the limiter
The limiter restricts the speed of the vehicle. To
reduce the speed to the set speed, the limiter
applies the brakes automatically.
You can limit the speed as follows:
Variable: for a short-term speed restriction,
R
e.g. in built-up areas
Permanent: for a longer-term speed restric-
R
tion, e.g. in winter tyre mode
You can store any speed above 20 km/h up to the
maximum design speed or up to the set winter
tyre limit. You can also perform settings while the
vehicle is stationary if the vehicle has been star-
ted.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognise
dangers ( page 182).

Mercedes‑AMG vehicles: the limiter is available
up to a maximum speed of 250 km/h.

A stored speed appears along with the È dis-
play. The segments in the speedometer light up,
up to the currently stored speed.
If you depress the accelerator pedal beyond the
pressure point (kickdown), the variable limiter
switches to passive mode. The Limiter passive
message appears in the Instrument Display and
the È display flashes.
The variable limiter is reactivated in the following
situations:
If the vehicle speed drops below the stored
R
speed.
If the stored speed is called up.
R
If you store a new speed.
