have friction linings at the sides to prevent exces­
sive wear. Degrease and clean the ball joint be­
fore using a stabiLiser. The stabiliser can be pur­
chased and installed
at
a qualified workshop.
Electronic stabilisation control
The
ESC
-
in particular in conjunction with the
trailer stabilisation system
o^page
97 - makes
it

easier to stabilise a trailer
if it
starts to skid
or

sway. You should therefore keep the
ESC
switch­
ed on
at
all times.
Overheating
In hot weather, keep an eye on the coolant
tem­

perature gauge
^page
13. When climbing long
hills with the engine running fast in low gear, the
coolant temperature can increase. Reduce speed
immediately
if
the needle moves to the right end
of the scale. For information on the warning
lamp
||
refer to
opage
30.

Rear carrier systems
When using rear carrier systems (e.g. bicycle
racks) on the towing bracket,
it
is important not
to exceed the maximum load.
The total weight
of
the rear carrier system and
its

load must not exceed
75
kg for this vehicle. How­
ever,
it
is also important to observe the maxi­
mum permissible load for the rear carrier sys­

tem.

The greater the distance from the towing brack­
et, the smaller the maximum permissible Load
on

the rear carrier system. For this reason, you
should secure heavy objects as near as possible
to the towing bracket.
Note the instructions provided by the manufac­
turer of the rear carrier system.
Please make sure that the rear carrier system
is

approved for use on your vehicle.

l
Note
A WARNING
The use of an unsuitable rear carrier system
could cause severe damage
to
the towing
bracket. The towing bracket could then break
and cause an accident.
Degrease and clean the ball joint before using
a rear carrier system.

Removable towing
bracket

Introduction
Applies to: vehicles with removable towing bracket
Special care is required when fitting and remov­
ing the towing bracket.

Fig.
84 Luggage compartment:
Ball
joint for towing brack­
et (stowage example)
The removable ball joint attachment for the tow­
ing bracket is stored under the floor panel or in a
separate bag on the floor of the luggage com­
partment.
The ball joint can be fitted and removed by hand.
WARNING
Never use tools of any kind when fitting and
removing the ball joint. This could damage
the mechanism which locks the
ball
joint
in

place and impair its safety
-
risk of accident!
© Note
- Do not attempt to modify or repair the ball
joint or other towing bracket components.
- Should you have any difficulties when using
the towing bracket, or suspect that
it
is not
fitted properly, contact
a
qualified work­

shop.

- Before setting off, always check that the

ball
joint is secured properly
Opage

Towing a trailer
- Never disengage the ball joint with the cara­
van / trailer still hitched or with a bicycle
rack or similar accessory still attached.
- It is advisable to remove the ball joint when
you are not towing a trailer. Check whether
the plug is properly inserted in the mount­
ing fixture and that the bumper cover is fit­

ted.

-The
ball
joint must be removed if
you
intend
to clean the car with a steam cleaning at­
tachment. Check whether the plug is prop­
erly inserted in the mounting fixture and
that the bumper cover is fitted.
- For installation and removal of the ball joint
we recommend using the gloves provided

for
this purpose.

knob is inside the green zone on the
ball
joint.

•
Check that the locking ball
(Î)
is inside the hole
in the shaft section of the
ball
joint.

•
Check that the knob protrudes visibly from the
ball joint, so that there is a clear gap (?) be­
tween the knob and the
ball
joint.
The
ball
joint can only be installed if the internal
spring mechanism is in the ready position.

the mounting fixture for the towing bracket.
Otherwise the ball joint may fail to engage
securely the next time it is attached if dirt
has accumulated in the mounting fixture.
- On vehicles in which the
ball
joint is stowed
in a bag on the floor of the luggage com­
partment, the bag must always be secured
to the front right fastening
ring.

Driver assist systems
provided tempt you into taking any risks when
driving - this can cause accidents.
- Please note that pre sense front can give
warnings or apply the brakes unexpectedly.
Always secure your luggage to prevent dam­
age and possible injury.
- Due to inherent system limitations, false ac­
tivation of the system is possible.
- Please note that the sensor is not always
able to detect all objects which may repre­
sent a potential hazard - risk of accident!
- Pre sense front does not react to the follow­

ing:
oncoming traffic in the same lane, sta­
tionary or stopped persons, pedestrians
crossing the road at an angle, groups of
people, animals, or objects that are hard to

recognise •=>
A in General notes on
page 112.
A WARNING
The pre sense front functions may be restric­
ted or unavailable in situations such as the

following:

- If objects such as crash barriers or other
vehicles are reflecting additional light.
- At tunnel entrances.
- In heavy fog,
rain,
road spray or snow.
- If the radar sensor is dirty, frosted, dam­
aged or covered.
- When driving through a corner.
-Applies to: front-wheel drive vehicles: If the
ESC system has been partially or fully deac­

tivated.

© CAUTION
Impacts or damage to the bumper, wheel
arches or underbody can cause misalignment
of the sensor. This can impair the function of
the pre sense front system. Have the systems
checked by a
quaLified
workshop.
© Note
-The automatic brake application with in­
creasing brake force can be cancelled by ap­
plying the brakes yourself or by pressing the
accelerator firmly or by taking evasive ac­

tion.

Driver assist systems
Rear cross-traffic assist
Applies to: vehicles with rear cross-traffic assist

Fig.
121 Example diagram

Fig.
122 Infotainment: Rear cross-traffic assist display
While you are reversing, the rear cross-traffic as­
sist can warn against a potential collision with
traffic approaching perpendicular to the rear of
the vehicle. The system uses the radar sensors

^page
128, Fig. 120 to monitor the area behind
and to the side of the vehicle when you are leav­
ing a parking space. Where possible, it detects
objects, such as cars, as they approach the
vehi­

cle
of/g.
121.
If critical cross-traffic is detected when reversing
out of a parking space, the system reacts as
fol­

lows:

- Graphic display: A graphic with a red arrow
symbol appears on the infotainment display.
The arrow indicates the direction from which
the object is approaching
^>Fig.
122.
- Warning tone: A tone may sound continuously
as an additional signal when you are reversing.
-Automatic
brake
jolt: A short sharp application
of the brakes may also warn against a potential
collision with an approaching object.
Requirements for the use of the rear cross-
traffic assist:
-The parking aid must be switched on

^>page
134.
- Reverse gear must be engaged.
- The speed must not be higher than approxi­
mately 12 km/h.

A
WARNING
- The purpose of the rear cross-traffic assist is
to assist the driver; it cannot prevent a
colli­

sion on its own. The driver must always in­
tervene personally. As the driver you are al­
ways responsible for braking in good time.
- Please note that the rear cross-traffic assist
may apply the brakes unexpectedly. Always
secure your luggage to prevent damage and
possible injury.
-After an automatic brake jolt, no further
brake jolt will occur within 10 seconds.
- If the rear cross-traffic assist gives an
acoustic warning signal, the parking aid may
no Longer be able to warn you against obsta­
cles it has detected.
- The radar sensor vision can be impaired, e.g.
by leaves, snow, heavy road spray or dirt.
Clean the area in front of the sensors

*>page
128, Fig. 120.

A
WARNING
The rear cross-traffic assist has certain inher­
ent limitations and cannot warn against an
impending collision in every situation:
- It cannot give a warning if the vehicle is so
far into a parking space that it is hidden by
the vehicles in front and behind.
- People such as cyclists, joggers, inline skat­
ers and pedestrians may not be detected in
certain situations.
- It cannot give a warning when you are
parked at an angle or parallel to the
road­

side.
