-The vehicle can also roll when the engine
is stopped .
- Unintended vehicle movement can cause
serious injury.
- Never leave your vehicle with the engine running whi le in gear. If you must leave
your vehicle when the engine is running, act ivate the park ing brake and move the
selector lever to P.
- Power is st ill transmitted to the wheels
when the eng ine is running at idle . To
prevent the vehicle from "creeping", you
must keep your foot on the b rake when
the engine is runn ing and the se lector
lever is in D/S or R or "tiptronic" mode is
selected .
- Do no t press the accelera tor pedal when
changing the selector lever position
whi le the vehicle is stationary and the
engine is running.
- Never shift into
R or P whi le driving.
- Be fore driv ing down a steep slope, re -
duce you r speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
peda l too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substant ially re­
duces braking performance, increases
braking d istance or causes comp lete fail­
ure of the brake system.
- To prevent the veh icle from rolling back
when stopping on inclines, always hold it in place with the brake peda l or parking
brake.
- Never hold the veh icle on an incl ine with
a slipp ing clutch . The clutch opens auto­
matically when it becomes too hot from
the ove rload. An ind icator lamp
[O] illu­
minates and a dr iver message appears
¢ page 114 when the clutch is overload ­
ed.
- If the eng ine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and is locked in P w
it h the park ing brake set
¢ page 227. Otherw ise, any increase in
engine speed may set the vehicle in mo­
tion, even with the parking brake ap­ plied.
(D Note
- When stopping on an incl ine, do not try
to hold t he vehicle in place by pressing
the acce lerator pedal while a driving gear
is se lected. This ca n cause the transmis­
sion to ove rheat and can damage it . Acti­
vate the pa rking brake or press the bra ke
peda l to preven t the vehicle from roll ing.
- Allowing th e vehicle to ro ll when the en­
gine is stopped and the selecto r lever is
in N will d amage the tr ansmission be­
cause it is not l ubricated unde r those cir ­
cumstances .
(D Tips
Fo r saf ety reaso ns, the pa rking br ake is re­
l eased automatically on ly when the d riv­
er's safety belt is engaged in the buckle.
Hill descent control
Appl ies to vehicles: wit h S t ronic/tiptro nic
The hill descent control system assis ts the
driver when driving down declines.
Hill des cent con trol is activated when these­
lector lever is in D/S and yo u press the brake
peda l. The transmission automatica lly selects
a gear that is suitable for the incline . Hi ll de ­
scent contro l tries to maintain the speed ach ­
ieved at the time of braking, within phys ica l
and technical lim itations. If may st ill be nec­
essary to adjust the speed with the brakes .
Hill descent cont ro l switches off once the de­
cline leve ls out or you press the acce lerator
pedal.

Side curtain airbags
Description of side curtain airbags
The side curtain airbag system can provide
supplemental protection to properly restrain ­
ed occupants.
Fi g. 1 69 Side curtain a irbags, d river 's side: side curta in
a ir bag location
The s ide curtain airbags are located o n both
sides of the interior above the front and rea r
side windows
c:.> fig. 169. They are ident ified
by the word "AIRBAG" on the windshield
frame and the center roof p illar.
The s ide curtain airbag system supp lements
the safety belts and can help to reduce the risk of injury for occupants' heads and upper
torso o n the side of the vehicle tha t is struc k in a side collision
. The side curtain airbag in­
flates in side impacts and only when the vehi­
cle acceleration registered by the control un it
is h igh enough . If this rate is below the refer­
ence value programmed into the control unit,
the side airbags will not be triggered, even
t h ough the car may be bad ly damaged as a re­
su lt of the co llision .
It is not possib le to de­
fine an airbag triggering range that will cover every possib le ang le of impact, s ince the cir­
cumstances will vary cons iderably between
one collision and another. Important factors
include, for example, the nature (hard or soft)
of the impacting object, the angle of impact,
vehicle speed, etc .
c:,, page 173, How side cur­
tain airbags work .
Aside from their normal safety function, safe­
ty belts work to help keep the driver or front
passenger in position in the event of a colli­
sion so that the side curtain airbags can pro­
vide protection .
The airbag system is not a substit ute for your
safety belt . Rather, it is part of the overall oc­
cupant restraint system in your vehicle. Al­
ways remember that the a irbag system can
only help to protect you if you are wear ing
you r saf ety belt and wearing it properly . This
is anothe r reason why yo u should always wear
yo ur safe ty belts, no t just because the law re ­
quires yo u to do soc:.>
page 140, General
notes .
It is important to remember that w hile the
s ide cur tain airbag system is designed to help
reduce the likelihood of ser ious injur ies, other
injuries, for example, swelling, bruising, fric­
tion burns and minor abrasions can also be as­
sociated w ith these airbags upon dep loyment.
Remember too, these airbags will deploy only
once and only in certain kinds of accidents -
your safety belts are always there to offer pro ­
tection.
The side curtain airbag sy stem basic ally
cons ists of:
- The electronic control module and external
side impact sensors ..,..

Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic*
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the deploy­
ment time is adapted in
Dynamic mode.
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
limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered :
- Braking guard
c::> page 92
- Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing 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 likeli­
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
Audi pre sense plus*
Audi pre sense plus includes the functions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected.
_& WARNING
-=
Audi pre sense cannot overcome the laws
of physics. It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the r isk of a collis ion and serious personal
in juries .
- The sensors cannot always detect all ob­
jects. This increases the risk of a colli­
s10n.
-Aud i pre sense does not detect people or
an im als or objects that are crossing the
veh icle's path
c::> page 86.
-The radar sensor's vis ion can be reduced
by heavy rain, ice, snow, heavy road sp ray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from being ac ­
curately detected and in some cases they
may not be detected at all.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly.
