Seats and storage
General recommen­
dations
Why is your seat adjustment so
important?
The safety belts and the airbag system can
only provide maximum protection if the front
seats are correctly adjusted.
There are various ways of adjust ing the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
you r seat prope rly so that :
- you can easily and quick ly reach all the
switches and controls in the instrument
panel
-your body is prope rly supported thus reduc­
ing physical stress and fatigue
- the safety be lts and airbag system can offe r
maximum protection
¢ page 145 .
In the following sec tions, you will see exactly
how you can best adjust you r seats .
There are special regulations and instructions
for insta lling a child seat on the front pas­
senger's seat. Always fo llow the information
regarding child safety provided in
q page 169, Child Safety .
A WARNING
Incorrect seating position of the driver and
all other passengers can result in serious
personal injury.
- Always keep your feet on the floor when
the vehicle is in motion -never p ut your
feet on top of the instrument panel, out
of the w indow or on top of the seat cush­
ion . Th is app lies especially to the passen­
gers .
If your seating position is incorrect,
you increase the r isk of injury in the case
of sudden braking or an acc ident.
If the
airbag infla tes and the seating position
is incorrect, this could resul t in personal
injury or even death.
- It is important for bo th the driver and
front passenger to keep a distance of at least 10 inches (25 cm) between them­
selves and the steering wheel and/or in­
strument panel. If you're s itting any
closer than th is, the a irbag system can­
not protect you properly . In addition, the
front seats and head restraints must be
adjusted to your body height so that they
can give you max imum protect ion.
- Always try to keep as much distance as
pos sible between yourself and the steer­
ing wheel o r instrument panel.
- Do not adjust the driver's o r front pas­
senger's seat whi le the vehicle is moving.
Your sea t may move unexpected ly, caus­
ing sudden loss of vehicle control and
personal injury . If you adjust yo ur seat
while the veh icle is moving, yo u are out
of posit ion.
Driver's seat '
The correct seat position is important for safe
and relaxed driving.
We recommend tha t you adjus t the dr iver's
seat in the fo llowing manner :
"' Adjust th e seat in fore and aft direction so
t ha t you can eas ily push the peda ls to the
floor wh ile keeping your knees sl igh tly bent
q A in Why is your seat adjustment so im­
portant? on page 54.
"' Adjust the backrest so that when you sit
w ith your back agains t th e backrest, you can
still g rasp the top of the steering wheel.
"' Adjust the head restraint so the upper edge
is as even as poss ible with the top of your
head . If that is not poss ible , try to adjust
the head restraint so that it is as close to
t his pos it ion as possib le
q page 61.
A WARNING
Neve r place any objects in the dr iver's foot ­
well. An object could get into the pedal
area and interfere with pedal function . In
case of sudden braking or an acc ident, you
would not be able to brake or accelerate .

62 Seats and storage
-Correctly adjusted head restraints and
safety be lts are an extreme ly effective
combination of safety features.

Adjusting steering wheel position
The steering wheel position can be adjusted
for height and reach .
Fig. 79 Switch for steer ing wheel adjustment
First , adjust the driver's seat correctly .
• To adjust the height, press the switch up/
down. The steering column will continue
moving as long as you are pressing the
switch.
• To move the steering wheel forward or back,
press the switch forward/back . The steering
column will continue moving as long as you
are pressing the switch.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steer­ ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detailed information on how to adjust the
driver's seat, see
Q page 55.
In vehicles with the memory function* , the
steering column settings are stored together
with the seat position.
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury. -
Adjust the steering wheel column only
when the vehicle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver's seat or steering wheel
so that there is a minimum of 10 inches
(25 cm) between your chest and the
steering wheel
Q page 128, fig . 136 . If
you cannot maintain this minimum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitt ing 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equipment is available.
- If the steering wheel is aligned with your
face, the supplemental driver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steering wheel is aligned with your
chest.
- Always hold the steering wheel with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal injury
if the driver's airbag deploys.
- Never hold the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub. Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

Audi braking guard
Description
Applies to vehicles: wit h adapt ive c ru ise control
Fig. 94 Instrument cluster: approach warn ing
Audi brak ing guard uses radar sensors and a
video camera . It is active at speeds above
about 6.2 mph (10 km/h) and also works
within system limits when adaptive cruise control is switched off.
On vehicles with aAdaptive cruise control and
Audi side assist (Audi pre sense plus), system
functions also engage when a co llision is im­
minent
¢page 188.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approaching a vehicle up
ahead that is moving more slowly. Audi brak­
ing guard does not react if it cannot detect
the situation.
The system advises you of various kinds situa­ tions :
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you will not be able to avoid a coll is ion. The ind icator
light
I i n the d isplay comes on. Take imme ­
diate action to avoid the coll is ion and in­
crease the distance to the vehicle up ahead. -
The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly that you are or if it
brakes sharp ly. When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharp ly . The indicator
light
I and the symbol in the disp lay will
warn you about the danger
c:> fig. 94 . You
w ill also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Aud i braking guard w ill
intervene by braking and the message
braking
guard intervention
w ill appear.
- If a coll is ion is imminent, the system will
first provide an
acute warning by brak ing
sharply .
- If you do not react to the acute warning, Au­
di braking guard will brake w ith increased
force in severa l stages to reduce the speed
in a possible collisio n. On ve hicles w ith
adaptive cruise contro l and Audi side assist
(Audi pre sense plus), the system can brake
with increasing force up to maximum decel­
eration shortly before a sensed collision
¢ page 188.
- If
the Audi braking g uard senses that you
are not braking hard enough when a colli­
sion is imminent, it can increase the braking
force.
Audi braking guard takes the driver's reaction
time into consideration in order to provide
timely warnings. The system reaction time de­ creases automatically in some situations, for
example when it detects accelerator pedal use
or steering input . The Audi braking guard in­
tervent ion stops in certa in situations, for ex­
amp le if you press the accelerato r pedal to
pass the vehicle moving ahead of you in your
lane.
Which functions can be controlled?
You can switch Audi braking guard and the
distance/approach warning on or off in the

Audi lane assist Lane assist
De scription
App lies to vehicles: with la ne ass ist
Lane assist helps you keep your vehicle in your
lane.
Lane assist uses a camera to detect lane boun ­
dary lines . If the system detects that your ve­
hicle is about to cross a detected lane boun­
dary line, the steering wheel
vibrates to alert
the driver . Lane assist is operable when the
line marking the lane is detected on at least
one side of the veh icle. This is ind icated by a
g reen indicator light. in the instrument
cluster.
If the system is in active standby mode and
the turn signal is activated before driving over
the bounda ry line, the warn ing does not occur
since the system allows for intentional lane
changes.
The system is designed for driv ing on free­
ways and expanded highways and thus works
only at speeds of 40 mph (65 km/h) or more.
A WARNING
- Lane assist will not keep your vehicle in
your lane . The system only warns the
driver when the vehicle is leaving the
lane . The driver is always responsible for
keeping the vehicle in the lane .
- The camera is not able to detect all lane
boundary lines and in some cases might
also detect lane structures or objects as
boundary lines . This can lead to incorrect
warnings or wa rnings tha t fail to go off
at all.
- The camera's visibility can be impaired by
vehicles ahead of you, for instance, or by
rain, snow, heavy spray o r light sh in ing
into the camera lens. Th is can cause lane
assist to fa il to detect boundary lines.
