Cruise Control - BMW 3 SERIES SEDAN Owner's Manual

Controls
When approaching a curve, the system may
react briefly to the vehicles in the next lane due
to the bend of the curve. Any deceleration of
the vehicle by the system can be compensated
for by briefly accelerating. After the accelerator
pedal is released, the system becomes active
again and independently controls the speed.
Driving away
In some situations, the vehicle cannot drive
away automatically, e.g., on steep inclines or
behind bumps in the road.

Cruise control

The concept
The system is functional at speeds beginning
at approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.
Unfavorable conditions
Do not use the system if unfavorable
conditions make it impossible to drive at a con‐
stant speed, for instance:
▷ On curvy roads.
▷ In heavy traffic.
▷ On slippery roads, in fog, snow or rain, or
on a loose road surface.
Otherwise, you could lose control of the vehi‐
cle and cause an accident.◀
General information
When ECO PRO is activated, cruise control is
also set to a driving style that saves on fuel
consumption.
