WARNINGThe sensor may not be able to distinguish all objects correctly under certain
circumstances. You should therefore not use ACC in the following cases -
risk of accidents!■
When driving through places where metal objects (such as metal build-
ings, railroad tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
CAUTION
Remove the snow with a brush and the ice with a solvent-free de-icer.

ACC status indications » Fig. 150
Control is inactive (the numbers of the speed indications are small and of a
grey color).
Control activated - no vehicle detected.
Control deactivated - no speed stored.
Control active - vehicle is detected (the figures of the speed indications
are displayed larger or are highlighted).
The ACC can consistently maintain the set speed of 30-160 km/h, as well as
the proximity to the vehicle ahead ranging from a very small to a very long
time interval.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
If the delay of the ACC is insufficient in relation to the vehicle in front, in the
instrument cluster, the warning light lights up and the display shows the
following message.
Apply the brake!
The ACC can detect a vehicle that is up to approx. 120 m ahead using the radar
sensor.
Note
Some ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.1234ABCD151Assist systems
Automatic stop-startRead and observe
and on page 150 first.
Vehicles with an automatic transmission can decelerate to a standstill and
start moving again using the ACC.
Decelerate to a standstill
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a standstill.
Starting to drive again after a holding period
As soon as the vehicle ahead starts moving again after a holding period, your
vehicle will also move and the speed will continue to be regulated. Control is
automatically disconnected in case of longer holding periods.
Depress the brake pedal.

The maximum trailer drawbar load is 75 kg.
For vehicles with all-wheel drive, the maximum trailer nose weight is 80 kg.
With G-TEC-vehicles, the maximum trailer drawbar load is 56 kg .
WARNING■
Before each time you make a journey when using the ball rod, check that
it is seated correctly and is secured in the mounting recess.■
Do not use the ball rod if it is not correctly inserted into the mounting re-
cess and secured.
■
Do not use the towing hitch if it is damaged or if there are parts missing.
■
Do not perform any modifications or changes to the towing device.
■
Never release the ball rod while the trailer is still coupled.
■
Keep the mounting recess of the towing device clean at all times. Such
dirt prevents the ball rod from being attached securely!
CAUTION
■ Take care when using the ball rod - there is a risk of paint damage to the
bumper.■
When the ball rod is removed always place the cover onto the mounting re-
cess - there is a danger of soiling the mounting recess.

Release ball bar
Read and observe and on page 169 first.
Firstly, carry out the 1st step of ball rod removal » page 172.
Release ball head - applies to both key versions
›
Grasp the ball rod from below » Fig. 176 .
›
Push release pin
A
in the direction of arrow
1
to the stop, and simultane-
ously push operating lever
B
in the direction of arrow
2
to the stop .
The ball rod is released in this position and falls freely into the hand. If it does not fall freely into the hand, use your other hand to push it upwards.
At the same time, the ball rod latches into the ready position and is therefore
ready to be re-fitted »
.
›
Place the cap
4
» Fig. 166 on page 169 onto the mounting recess.
WARNINGNever allow the ball rod to remain unsecured in the boot. This could cause
damage to the boot upon sudden braking, and could put the safety of the
occupants at risk.
CAUTION
■ If lever B is held firmly and not pushed downwards to the stop, it will move
back up after the ball rod is removed and will not latch into the ready position.
The ball rod will then need to be brought into this position before the next
time it is fitted » page 170, Adjusting the ready position .■
Store the ball rod in the box in the ready position and with the key facing up-
wards - otherwise there is a risk of damage to the key!
■
Do not use excessive force when handling the operating lever (e.g. do not
climb on it)!
Note
Remove any dirt from the ball rod before stowing it away in the box with the
vehicle tool kit.
