Selecting The Drive Program; Changing Lanes; Stopping With Distronic Plus; Setting A Speed With Distronic Plus - Mercedes-Benz GLA Operator's Manual

If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
The vehicle is only accelerated up to the
speed you have stored.

Selecting the drive program

DISTRONIC Plus supports a sporty driving
style when you have selected the S or M driv-
ing program ( page 152). Acceleration
Y
behind the vehicle in front or to the set speed
is then noticeably more dynamic. If you have
selected the E driving program, the vehicle
accelerates more gently. This setting is rec-
ommended in stop-and-start traffic.

Changing lanes

If you change to the passing lane, DISTRONIC
PLUS supports you when:
you are driving faster than 43.5 mph
R
(70 km/h)
DISTRONIC PLUS is maintaining the dis-
R
tance to a vehicle in front
you switch on the appropriate turn signal
R

If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
