Safety tips
T he s ide ass is t de tect io n may be limited whe n drivi ng a round
narrow street corners, on hilly streets, and under poor weather
c o ndition s.
It is possibl e that the radar sensors may also detect other ob jects,
suc h as h igh or s tagge re d guar drails. S
ide assist does not measure actua l lane width . The sys tem
assumes a fixed la ne wid th. Dete cti on in th e le ft an d rig ht l anes is
based on this assumed lane width . When d riv ing on narrow roads or
w hen driving to t he left or right of the ce nte r of a travel la ne, it i s
possible that vehicles will be detected that are
not in th e lane next
to the lane yo u are us ing.
& WARNING
• Improper reliance on the side assist system can cause colli ­
sions 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 assist 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 ml.
• 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. .,,_

& WARNING
• The rear -view camera has blind spots, in which objects cannot
be detected . Be especially careful to check for small children and
animals before backing up. Small children and animals will not
always be detected by the sensors .
• The Audi parking system is not a substitute for being careful
and alert when backing up. Be especially careful during parking
and similar maneuvers . Always watch where you are driving and
make sure that nothing is in the way .
• Remember that low obstacles which have already been
signaled may pass below the system's sensing zone when the
vehicle is backing up . The fact that the signal stops does not mean
that you have cleared the obstacle. When the signal stops , impact
is imminent . Objects such as trailer hitches, chains , narrow posts
or fences covered by a thin layer of paint may not always be
detected by the system. They can still damage your vehicle
without warning .
• Always make sure that the volume and frequency of the chimes
is adjusted so that you can easily hear the acoustic distan ce signal
even if the radio is playing , the air-conditioner blower is on High or
there is a high level of outs ide noise .
- Check the settings whenever someone else has driven the
vehicle before you.
• Improper reliance on the Audi parking system can cause colli ­
sions and serious personal injury .
- Never rely only on parking assist when changing backing up.
- Always check rear view mirrors to make sure it is safe to back
up.

& WARNING (continued)
• Maintain plenty of distance from an obstacle, so that your
outside mirror or a corner of your vehicle does not collide with any
obstacles -danger of accident!
• The Audi parking system is not a substitute for being careful
and alert when backing up. Be especially careful during parking
and similar maneuvers. Always watch where you are driving and
make sure that nothing is in the way.
• When maneuvering or parking , do not only use the MMI Display
for orientation. Certain objects -depending on the screen resolu­
tion -may not, or not entirely, be displayed; for example trailer
hitches , chains, narrow posts, or fences . •

Use only floor mats that leave the pedal a rea unobstructed and that
are firmly secured so that they cannot slip out of position. You can
ob tain sui table floor mats from your au thorized Audi dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached to these fasteners .
Properly securing the floor mats will prevent them from sliding into
positions that could interfere with the pedals or impair safe opera­
tion of your vehicle in other ways .
& WARNING
Pedals that cannot move freely can result in a loss of vehicle
control and increase the risk of serious personal injury.
• Always make sure that floor mats are properly secured.
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to
control the vehicle .
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning.
• Always make sure that objects cannot fall into the driver foot·
well while the vehicle is moving. Objects can become trapped
under the brake pedal and accelerator pedal causing a loss of
vehicle control. •

& WARNING
• You should perform braking maneu vers for the purpose of
cleaning the brake system only if road conditions permit . Other
road u sers mu st not be put at r isk -you may cause an a ccident!
• Before des cending a steep grade, reduce speed and shift trans ­
mission into a lower gear or lower dr iving range . Do not ride the
brakes or hold the pedal down too long or too often. This could
cause the brake s to get hot and diminish braking effi ciency .
• Do not "ride the brakes " by resting your foot on the pedal when
you do not intend to b rake. This may cause the br ake s to ove rheat ,
premature wear and increased stopping distance.
• Under ce rtain climat ic and operating condit ions such as
passing through water , driving in heavy rain or after washing the
vehi cle , the effectiveness of the brakes can be reduced . In winter ,
ice can a ccumulate on the brake pads , linings , discs and drums .
Carefully apply bra kes fo r a test . Brakes will dry and ice coatings
will be cleaned off after a few careful brake appli cations .
• Driving for an extended period of time on salt -co vered roads
without using your brakes can also affect braking effic iency. Clean
off accumulated salt coating from brake dis cs and pads with a few
c areful brake applications .
• If you damage the front spoile r, or if you install a different
spoiler, be sure the air flow to the front brakes is not ob structed.
Otherw ise the brake sy stem could overheat reducing the effective­
ness of the entire brake system .
• Failure of one bra ke cir cuit will impair the braking capability
resulting in an increased stopping distance. Avoid driving the
vehicle and ha ve it towed to the nearest authorized Audi dealer or
qualified workshop . •
Brake booster
T he b rake boost er ad ds extra b ra kin g powe r.
The brake booster works with vacuum pressure which is created
o nly w he n t he e ngine is ru nnin g=> & .
& WARNING
• Never let the vehicle roll to a stop with the engine shut off.
• If the brake booster is not working, for example when towing
your vehicle, or because the brake boo ster has somehow been
damaged , the brake pedal must be pressed considerably harder to
make up for the lack of booster assistance . •
Functioning of A!"lt"-Lock Brake System (ABS)
ABS p revents the wheels from locking up unde r brakin g.
Th e ABS co ntribu tes effect ively to vehicle cont ro l since it preve nts
the whee ls from
locking when the brakes are app lied. This means
t h at the ve hicle rema ins steerable and is less l ikely to s kid.
With ABS you do not need to pump the brake . Just hold the brake
pedal down .
However, do not expec t the A BS to s hor ten bra king d istance u nder
all circumstances. When driving o n grave l or on newly fallen snow
o n t op o f icy sur faces, brak ing d istance may be ev en lon ger, the re­
fore, under these c ircumstances, it is especially important that you
driv e slow ly an d with gre at ca re.
How the ABS system works
An a utomatic c heck is m ade w hen a speed of about 1 2 mph (2 0
km/h) is reached. When this happens, a pumping noise can be
h ea rd.
