Child safety
-When buying a child restraint, select one
that fits your child and the vehicle.
- Only use child restraint systems that fully
contact the flat portion of the seat cush­
ion. The child restraint must not tip or
lean to either side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames . They do not pro­
vide adequate contact with the seat.
- Always heed all legal requirements per­
taining to the installation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using.
- Never allow children under 57 inches
(1.45 meters) to wear a normal safety belt.
They must always be restrained by a proper
child restraint system. Otherwise, they
could sustain injuries to the abdomen and
neck areas during sudden braking maneu­
vers or accidents.
- Never let more than one child occupy a child
safety seat.
- Never let babies or older children ride in a
vehicle while sitting on the lap of another
passenger .
- Holding a child in your arms is never a sub­
stitute for a child restraint system.
- The strongest person could not hold the
child with the forces that exist in an acci­
dent. The child will strike the interior of
the vehicle and can also be struck by the
passenger.
- The child and the passenger can also in­
jure each other in an accident.
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat. A child will be seriously injured and
can be killed when the passenger airbag in­
flates -even with an Advanced Airbag Sys­
tem .
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof .
- Always install rear-facing child safety seats
or infant carriers on the rear seat .
172
-Forward-facing child safety seats installed
on the front passenger's seat can interfere
with the airbag when it inflates and cause
serious injury to the child . Always install for­
ward-facing child safety seats on the rear seat .
- If exceptional circumstances require the use
of a forward-facing child restraint on the
front passenger's seat, the child's safety
and well-being require that the following
special precautions be taken:
- Make sure the forward-facing seat has been designed and certified by its manu­
facturer for use on a front seat with a pas­
senger front and side airbag .
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
- Always move the front passenger seat into
the rearmost position of the passenger
seat's fore and aft adjustment range, and
as far away from the airbag as possible be­
fore installing the child restraint.
- Always make sure that nothing prevents
the front passenger's seat from being
moved to the rearmost position in its fore
and aft adjustment range.
- Always make sure that the backrest is in
the upright position.
- Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a collision.
- Always read and heed all WARNINGS when­
ever using a child restrained in a vehicle is
being used¢

Child safety
The airbag on the passenger side makes the front
seat a potentially dangerous p lace for a child to
ride. The front seat is not the safest place for a
child in a forward-facing child seat. It is a very
dangerous place for an infant or a larger child in
a rearward-fac ing seat.
A WARNING
Not using a ch ild safety seat, using the wrong
child safety seat or improperly installing a
child restra int increases the r isk of serious
personal inju ry and death in a crash.
- Never install rear-facing chi ld safety seats
or infant carriers on the front passenger
seat -even with an Advanced Airbag System.
A chi ld will be seriously injured and can be
killed when the inflating airbag hits the
child safety seat or infant carrier with great
force and smashes the child safety seat and
child against the backrest, center armrest,
door or roof
c::, page 147, Child restraints on
the front seat -some important things to
know.
- Always install rear-facing child safety seats
or infant carr iers on the rear seat.
- Never install a rear-facing child restra int in
the forward-facing direct ion. Such restraints
are designed for the spec ial needs of infants
and very sma ll children and cannot protect
them properly if the seat is forward-fa cing.
- If you must install a rearward fac ing ch ild
safe ty seat on the front passenger seat be­
ca use of exceptiona l circumsta nces and the
PASSENGER AIR BAG OFF light does not
come on and stay on, immed iate ly install
the rear-facing chi ld safety seat in a rear

Audi pre sense Preventative passenger
protection
A ppl ies to: ve hicles with Audi pre se nse
Audi pre sense can initiate steps to help protect
vehicle occupants in certain situations. The func­
tions described depend on equipment installed in
your veh icle:
Audi pre sense basic
The following functions can be triggered in cer­
tain driving situations:
- Tightening of the safety belts (for examp le,
during heavy braking): the front safety belts
have reversible belt pretensione rs. If a collision
does not occur, the safety belts loosen slightly
and are ready to be t ightened again.
- Closing the windows and the sunroof*: the win­
dows and the sunroof* close leaving a small
open gap .
Audi pre sense basic functions can be triggered at
speeds above 20 mph (30 km/h). The deploy­ ment time is adapted in the drive select mode dy­
namic.
Audi pre sense front (vehicles with adaptive
cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic . In addition, within the lim ­
its of the system, the likelihood of a collision
with the vehicle immediately ahead is also calcu­ lated.
If the system senses an imminent collision
the following functions can be triggered:
- Braking guard
~ page 96
- Tightening the safety belts
- Closing the windows and the sunroof* (leaving
a small open gap)
Audi pre sense rear (vehicles with Audi side
assist*}
Audi pre sense rear includes the functions in Audi
pre sense basic. In addition, the likelihood of a
rear-end collision with the vehicle coming from
behind is also calculated.
If the risk of a collision
is detected , the following functions can be trig­
gered:
Audi pre sense
-Tig htening the safety belts
- Closing the windows and the sunroof* ( leaving
a small open gap)
- Adjusting the seats: the settings for the power
head restrains, the upper sections of the backr­
ests and the pneumatic side bolsters* are opti­ mized for the front seats and the outboard rear
seats*. If a co llision does not occur, the previ­
ous seat settings are restored.

Error message
Audi pre sense: not available
Preventative passenger protection is not availa­
ble . See your authorized Audi dealer immediately
to have the malfunction corrected .
A WARNING
-
Audi pre sense cannot overcome the laws of
physics. It cannot prevent a collision. Do not
l et the increased safety provided tempt you to
take risks. This will increase the risk of a colli­
sion and serious personal injuries.
- The sensors cannot always detect all ob­
jects. This increases the risk of a collision.
-Audi pre sense does not detect people or an­
imals or objects that are crossing the vehi­
cle's path
~ page 90.
-The radar sensor's vision can be reduced by
heavy rain, ice, snow, heavy road sp ray and

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first ¢
.1:,.. The break-in pe­
riod can be considerably longe r fo r vehicles with
192
ceramic brake rotors*. You can compensate for
this slightly reduced braking power by push ing
harder on the brake pedal. Avoid heavy braking
lo ads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub ­
j ect to wear, depending large ly on operating con­
ditions and driving habits¢,& . On vehicles that
are either driven mostly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of ­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the brak ing ef­
fect of the engine. T his way, you prevent unnec­
essary wea r on the brake system. If you mus t use
your brakes, do not hold the brakes down contin-
u ously. Pump th e brakes at intervals. ..,.
