Speed control cruise control
Function of cruise control
Cruise control regulates the speed to the value
selected by the driver.
If you accelerate to overtake, forexample, the
stored speed is not deleted. If you remove your
foot from the accelerator pedal after overtaking,
cruise control will resume speed regulation back
to the stored speed.
You can store any speed above 15 mph
(20 km/h) up to the maximum design speed.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers (
/
page 211).
Mercedes‑AMG vehicles: cruise control is availa-
ble 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 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 overheating and wearing
too quickly.
Do not use cruise control in the following situa-
tions:
R
in traffic situations which require frequent
changes of speed, e.g. in heavy traffic, on
winding roads
R
on slippery roads. Accelerating can cause the
drive wheels to lose traction and the vehicle
could then skid.
R
when visibility is poor
