Start/stop
mode when adaptive cruise
control (ACC) is active
The engine will be switched off after the adaptive
cruise control (ACC) has brought the vehicle to a
standstill with an active braking intervention
~page 226.
In the following instances, the engine will restart
when the ACC is active:
• If the accelerator is depressed.
• When the ACC has resumed speed and dis
tance control.
• If the vehicle ahead has moved on.
The brake servo and the electromechanical
steering will not function if the engine is
switched off.
• Never allow the vehicle to roll if the engine
is switched off.
• The start/stop system must be deactivated
if work is to be carried out in the engine com
partment.

The downhill driving assistant in veh icles with an
~utomatic gearbox helps when braking and travel
ling downhill ~ £. The downhill driving assistant
uses the braking power of the engine .
The automatic gearbox selects the best gear for
t~e circums tances by taking the steepness of the
h1l.l and the current speed into consideration. To do
th1s the selector lever must be in position D or S.
The downhill driving assistant is not active in Tip
Ironic mode .
As the downhill driving assistant can only shift
down as far as the 3rd gear, it may be necessary
to activate the Tiptronic mode when driving down
If the start/stop system is used in very high

A parking manoeuvre will be interrupted if a speed
of approximately 7 km /h (4 mph) is exceeded .
Automatic brake intervention to avoid
excess speed
An automatic brake intervention may occur to pre

it, pull out of the parking space.
Automatic cancellation for getting out of a

The Park Assist system will cancel the procedure
of getting out of the parking space if one of the fo l

• The vehicle speed when getting out of the park
ing space is higher than approximately 7 km/h
(4 mph).
• The driver operates the steering wheel.

A WARNING
Do not let the extra convenience afforded bY
the P~rk Assist system tempt you into takin~
any nsks when driving -this can cause accl
dents. The system is not a substitute tor the

Always switch off the speed limiter after use
to avoid unintentional cruise control.
• The speed limiter does not relieve the
driver of their responsibility for the speed of
the vehicle. Do not drive at full throttle if it is
not required.
• Use of the speed limiter in adverse weath·
er conditions is dangerous and can cause se
rious injury, e.g. through aquaplaning, snow,
ice, or leaves. Only use the speed limiter
when the road and weather conditions allow
it to be used safely.
• The speed limiter cannot limit the vehicle
speed when travelling downhill. The vehicle
speed can increase under its own weight.
Shift down a gear or brake the vehicle using
the foot brake.

Setting the driving programme
In vehicles with Driving Mode Selection , the selec
t~d driving mode can affect the vehicle 's accelera

The following driving modes can be selected :
• Normal
• Sport

In v h' . e lcles Without Driving Mode Selection , the ac-
Celeration response can be affected by the driving
rnode s I IT.Dl ~a e ected by pressing the ~ butto.n and _ the
I . nd @nver assistance ) function buttons 1n the 1nfoa1nrne t n system ~page 31 .
The following conditions can prevent the
adaptive cruise control from reacting:
• If the the acce le rator is depressed.
• If no g ear is selected .
• If the ESC is taking corre ctive action .
• If the driv er h as no t f astened seat belt.
• If there is a fau lt in seve ral brake lights on the
v e hicle or on a traile r with an electrical
connection
to the vehic le .
• If the vehicle is reve rsing .
• If the vehicle is travelling faster than approxi
mately 160 km/h (100 mph).
A WARNING
If you close the gap to a vehicle in front and
the difference in speed between the two vehi
cles is so great that the braking action of the
ACC is insufficient, you are in danger of col
liding with the vehicle in front. You should re
duce the vehicle speed immediately with the
foot brake.
• The ACC may not be able to recognise all
driving situations correctly.
• Leaving your foot on the accelerator will
mean that the ACC will not brake automatical
ly. This is because manual acceleration over
rides the system.
• You should always be prepared to brake
the vehicle yourself.
• Observe country-specific regulations re
garding the minimum distance.
rn
The set speed will be deleted if the ig nition or
the ACC is switched off.
rn
The ACC is automatically deactivated when
the tract ion control system (T CS ) is deactiva-
ted .
rn
In vehicles with a start/stop system, the e n
g ine is switched off automatical ly during the
stat ionary phase of ACC and is then restarted for
moving off.
