© Signal on outside mirror does not light up
A vehicle approach ing s low ly- in the left-hand lane for example -was
detected by the sensors. Because of the small difference in speed and
the considerable distance from your vehicle, the signal on the outside
mirror will not light up=>
& in "Safety tips" on page 145 .
@ Informational stage signal lights up
The distance between your vehicle and that of the slowly approaching
vehicle has narrowed . The informational stage signal on the outside
m irror lights up.
As soon as the difference in speed and distance is registered as
notable if you were to change lanes, a signal on the mirror lights up.
Side assist will signal at the latest when a detected vehicle enters
your "blind spot" .
@ Alert stage signal flashes
If you activate your turn signal in dr iving s ituation @, the signal light
briefly flashes repeatedly. Side assist is alerting you of a vehicle that
you may not have noticed.
[ i ] Tips
• T he faste r a vehicle approaches from the rear, the sooner the
signal on the outs ide mirror lights up. S ide assist will signal, at the
latest, when a detected vehicle enters your "blind spot".
• When vehicles approach very quickly, changing lanes can be
dangerous even if the signal on the outside mirror does not light up.•

Safety tips
T he side assist detect io n may be limited when driving a ro u nd na rrow
s tr ee t co rner s, on hilly stree ts, and und er poor we ather cond itio n s.
Controls and equip ­
ment Safety first
It
is possible that the rada r senso rs may a lso detect o ther objects,
such a s high or stag gere d guar drails.
S ide assis t does not measure actua l lane w idth. The system assum es
a fi xed la ne w idt h. Detection in the left and right lanes is based on
t hi s a ssumed lane w id th. Wh en driving o n narrow ro ads or w he n
dr iv ing to the left or rig ht of the center of a travel lane, it is poss ible
t h at vehicles will be de tected tha t a re

& WARNING
• Improper reliance on the side assist system can cause collisions
and serious personal injury:
-Never rely only on side assist when changing lanes .
- Always check rear view mirrors to make sure that it is safe to
change lanes.
• Side assist cannot detect all vehicles under all conditions­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly .
• The radar sensor's
vision can be reduced or entirely blocked by
rain, snow, and heavy spray. This can result in side assist not
adequately detecting vehicles or, in some cases , not detecting
them at all. Always keep an eye on the direction you are traveling and the relevant area around the vehicle .
• Please note that side ass ist indicates there are approaching
vehicles, or vehicles in your blind spot, only after your vehicle has reached a driving speed of at least 19 mph (30 km/h).
• Side assist signal does not work around tight corners (turning
radius less than 328 feet, or 100 m ).
• Side assist is no replacement for the driver's full attention . The
driver alone is responsible for lane changes and similar driving
maneuvers. Always keep an eye on the direction you are traveling
and the relevant area around the vehicle. .,,

Parking system
Different park assist systems may be used for parking or
maneuvering , depending on the vehicle's features .
Parking system (rear)*:
For the parking system (rear), th e acoust ic park assist system is
installed in the rear of the vehicle~
page 158.
The rear pa rk ing assist system uses ultrasonic sensors to determine
the distance of the vehicle from a detected obstacle. There are a tota l
o f f our sensors located on the rear bumper (two in the m iddle and
two on the sides) .
Parking system (rear, with rear view camera)*:
For the parking system (rear , with rear view camera), the rear
aco ust ic park assist sys tem is integra ted in the rear of the vehicle and
the rear view camera is integrated in the rear lid~
page 162.
The parking system (rear, with rear view camera) uses ultrasonic
sensors to determine the d istance of the vehicle from a detected
obstacle. There are a total of four sensors located on the rear bumper
(two in the m iddle a nd two on the sides). •

Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car .
Description
The rear acoust ic par king assist sys tem determines the d ista nce of
the vehicle from an obstacle using ultrason ic sensors . There are 4
sensors in the rear bumper .
T he range at which the sensors start to measure is
about :
To the side
Center rear
Act ivation 2
ft (0.60 m)
5
.2 ft (1.60 m)
Aco ust ic parking assist is act ivated automatically when
re ver se gear
is engaged . A b rief tone confirms that the system is activated .
Warning tones
Distance warning is given by warning tones which are generated by
t he rear signa l generator. The volume and the p itch o f the warning
tones can be adjusted in the MMI*
~ page 159 .
Reversing
Distance warning when reversing starts when an obstacle is detected
in the range o f the pa rking assist system. As the d istance decreases,
the time interval between the audible tones becomes shorter .
When the distance is less than 1ft (0.30 m), the tone becomes
c ont inuous. At this point you should stop back ing up.

___________________________________________________ P_a _r _k _ a_s _s_ i_s _t __ _
Please note that low objects a lready s ignalled by a war ning can disap­
pe ar from the sys te m 's d etection r ange and will not co nti nue to be
signa lled .
If the distance to an obstacle remains t he same, the vo lume of the
dis tan ce warn ing is gradu ally redu ced af ter abou t 4 seco nds.
Approaching another obstacle will result in the distance warning
s ou nding a t th e normal vo lume aga in.
Malfunctions in the system
If a wa rning tone is aud ible fo r about five seconds when you turn o n
the ignition , there is a ma lfunction in the system. Have the prob lem
c o rrected by yo ur auth orized Aud i de aler.
Keep the sensors in the rear bumper clean and free from ice so t hat
t he acous tic par k ass ist system can func tion prope rly.
& WARNING
• Sens ors have dead space s in whi ch objects cannot be dete cted.
Be especi ally alert for small children and animals , since they are
not alway s detected by the sen sors.
• The acou stic parking system is not a substitute for the dr iver 's
own caution and alertne ss. Ultimate respon sibility alway s
remains w ith the driver during parking and similar maneuvers.
Alway s w atch wh ere you are driving .
• You should always adjust the volume and frequency of the
warning tone s so that you can e asily hear the acoustic di stan ce
wa rning e ven if the radio is pl aying, the air -conditioner blowe r is
on High or there i s a high level of out side noi se .

Switching on/off
The rear view camera switches on automatically together
with the acoustic park assist when you put the vehicle in
reverse.
Switching on
- Put the vehicle in reverse gear, the acoustic parking
system with rear view camera is activa ted automatically .
Activation of the acoustic parking system is confirmed by
a brief acknowledgement sound.
Switching off
-Drive faster than 6 mph (10 km/h), or
- take the vehicle out of reverse gear. The acoustic parking
system is immediately deactivated, and the rear view
camera picture is deact ivated automatically after a period
of about 15 seconds, or
- switch off the ignition.
T he delay in deactivating the camera provides an uninterrupted view
behind the vehicle espec ially when maneuver ing in tight parking
spaces and prevents the picture from tu rning off the every time you
shift out of reverse .
If the warning message appears in the display but not the rear view
came ra pict ure, read and confi rm the warning message . T he acoustic
distance s ignal is always active. If
you press a function button on the MMI control console, the rear
view came ra pictu re disappears. The rear view camera pict ure reap­
pears the next time you park .

Unfastening safety belts
Unbuckle the safety belt with the red release button only
after the vehicle has stopped.
Fig . 176 Releasing
the tongue from the
buckle
- Push the red release button on the buckle=> fig. 176. The
belt tongue will spring out of the buckle=>& .
- Let the belt wind up on the retractor as you guide the belt tongue to its stowed position.
& WARNING
Never unfasten safety belt while the vehicle is moving. Doing so
will increase your risk of being injured or killed. •
Improperly worn safety belts
Incorrectly positioned safety belts can cause severe inju­
ries.
Wearing safety belts improperly can cause serious injury or
death. Safety belts can only work when they are correctly
positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and will even increase the
risk of injury and death by moving the safety belt to critical areas of the
body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys
and strikes an occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all vehicle occu­ pants and especially for children. Therefore:
- Never permit anyone to assume an incorrect sitting posi­
tion in the vehicle while traveling=>&.
& WARNING
Improperly worn safety belts increase the risk of serious personal
injury and death whenever a vehicle is being used.
• Always make sure that all vehicle occupants are correctly
restrained and stay in a correct seating position whenever the
vehicle is being used.
• Always read and heed all WARNINGS and other important
information ~
page 184. •
Safety belt pretensioners
How safety belt pretensioners work
In front, side and rear-end collisions above a particular
severity, safety belts are tensioned automatically .
The safety belts are equipped with safety belt pretensioners. The
system is ac tivated by sensors in fron t, side and rear-end collisions of
great severity. This tightens the belt and takes up belt slack~
& in
"Service and disposal of safety belt pretensioner" on
page 189 .
Taking up the slack helps to reduce forward occupant movement
during a collision. .,
