(depending on equipment and not available in
all countries).
Overtaking
If you indicate left (left-hand traffic: indicate
right) to overtake, ACC will accelerate the ve-
hicle and reduce the distance from the vehi-
cle in front. Your set speed will not be excee-
ded.
If ACC does not detect any vehicle in front af-
ter you have changed lane, ACC will acceler-
ate the vehicle up to the set speed.
Overtaking assistance is not available in all
countries.
Stop-and-go traffic
ACC can brake the vehicle to a standstill and
keep it stationary. ACC remains active and
the instrument cluster display shows
ACC ready
to start
for a few seconds.
On vehicles with Travel Assist, you can extend
this time by continuing to hold the steering
wheel.
As long as ACC remains active, the vehicle
will move off again automatically as soon as
the vehicle in front moves off (depending on
the vehicle equipment level and not available
in all countries).
Extending or reactivating readiness to drive:
— Press the
button.
Vehicles with Travel Assist:
alternatively
grasp the steering wheel again.
Moving off when readiness to drive has
ended and the vehicle in front has already
moved away:
— Press the
button or briefly depress the
accelerator.
ACC remains inactive in the following cases:
— The vehicle is stationary for several mi-
nutes.
— A vehicle door is opened.
— The ignition is switched off.
WARNING
If the message
ACC ready to start
is shown on
the instrument cluster display and the vehi-
cle in front moves off, your vehicle will
move off automatically. In some cases, ob-
stacles in the vehicle's path may not be de-
tected. This can result in serious injury and
accidents.
·
Always check the road ahead before
moving off and brake the vehicle if nec-
essary.
Inside Overtaking Prevention System
Fig. 103 On the instrument cluster display:
slower vehicle detected in the left-hand lane (il-
lustration).
If ACC detects a slower vehicle in the left-
hand lane (left-hand traffic: in the right-hand
lane), ACC will brake the vehicle gently within
the system limits and can therefore prevent
a prohibited overtaking manoeuvre. The
function is active from speeds of around
80 km/h (around 50 mph), but is not available
in all countries.
