to make certain it is f unct io ni ng proper ly a t all
times. Eac h time you switch on the ignition,
the airbag system indicator light wi ll come on
for a few seconds (se lf diagnost ics) .
The side curtain airbag is not activated:
-if the ign ition is swit ched off,
- i n s ide coll isions when the accelerat ion
measured by the sensor is too low,
- in rear-end collisions .
_& WARNING
-Sa fety belts and t he a irbag system w ill
only p rov ide p rotection whe n occu pan ts
are in the proper sea ting posit ion
¢ page 5 2, General recommendations.
- If the airbag indicator light ¢ page 19
comes when the vehicle is be ing used,
have the system inspected immediate ly
by you r aut ho rized Audi dea ler . It is pos ­
sible that the airbag will inflate when it
is not s upposed to, or w ill not inflate
when it sho uld.
How side curtain airbags work
Side curtain airbags can work together with
side airbags to help reduce the risk of head
and upper torso injuries for occupants who
are properly restrained .

The side c urtain airbags infla te between the
occupant and the windows on the side of the
vehicle that is struck in a side coll is ion
¢ fig . 169.
When the system is trigge red, t he side curta in
airbag is filled with propellant gas and breaks
th ro ugh a seam above the front and rear side
windows identified by the AIRBAG labe l. In or­
der to he lp provide this additional protection,
the side curta in a irbag must inflate withi n the
blink of an eye at ve ry hig h speed and with
great fo rce . T he side curta in a irbag could in­
j u re yo u if your sea ting posit io n is not proper
o r u pright or if items are loca ted in t he a rea
where the supplemental side curta in a irbag
in flates . This applies especially to chi ld ren
~ page 175 .
Although they are no t a soft pillow, side cur­
ta in a irbags can "cushion" the impact and in
this way they can help to reduce the risk of in­
j u ry to the head and the uppe r part of the
body .
A fine dust may deve lop when the airbag de­
ploys . This is qui te no rma l and does not mean
there is a fire in the vehicle .
Important safety instructions on the
side curtain airbag system
Airbags are only supplemental restraints . Al­
ways properly wear safe ty belts and ride in a
proper seating position.
There is a lot that you and your passengers
must know and do to help the safety belts and
airbags do t heir job to provide supplemental
protection .
_& WARNING ...__
Improperly wea ring safety belts and im­
p roper seating posit ions increase the risk
of ser ious perso nal inj ury and death when­
ever a vehicle is being used.
- Never let occupa nts pla ce any pa rts of

194 Audi pre sense
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.

sponges to prevent scratches. It is best
to use soapy water .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never clean the head­
lights w ith a dry cloth or sponge. Use a
wet cloth or sponge. It is best to use
soapy water .
@ For the sake of the environment
Only wash the vehicle in facilit ies specially
designed for that purpose. Th is w ill reduce
the risk of d irty water contaminated with
oil from entering the sewer system . In
some areas, washing veh icles outs ide of
t hese facilit ies is prohib ited.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you
observe a few simple rules .
.,. Befo re using the power washe r, make sure
you have read and understood the WARN­ INGS ¢
A. in General information on
page 213.
.,. Always fo llow the operating instructions for
the power washer .
.,. Make sure that the jet on the spray hose
produces a "fan shaped spray" .
.,. Do
not ho ld the spray no zzle too close to
soft mate ria ls .
Keep a d istance from soft materials such as
rubber hoses or insulat ing mater ial as we ll as
sensors and camera lenses .
When clean ing the vehicle w it h a power wash­
er
always follow the operating instructions.
This applies particularly to the operating pres­
sure and the spraying distance . Do not po int
the spray directly at t he sea ls around the side
windows, aro und the doors, o n the rea r lid or
on the sunroof *. L ikew ise, do not point it di­
rectly at tires, r ubber hoses, ins ulation mate­
rial or sensors ¢
page 216. Hold the spray
Cleaning and protec tion 215
nozzle at least 1.3 ft (0.4 m) away from the
vehicle.
Do no t use a high-p ressure power w asher to
remove snow and ice .
Do not use a jet which sprays wate r in a d irect
stream o r one that has a rotating jet.
Water temperature should not exceed 140 °F
(60 °() .
A WARNING
Neve r wash t ires with a jet that sprays wa­
ter in a direct stream . Thi s could cause in­
v isible damage to the t ires and we aken
them, even if the spray is from a re lative ly
l ong dis tance and for a short time. Dam ­
aged and wea kened tires can fail and cause
accidents and personal in jury.
(D Note
To avoid damaging yo ur vehicle, a lways
make sure tha t the re is sufficien t distance
between the s pray head and soft materia ls
lik e rubber hoses, plastic parts and sound­
deaden ing mater ia ls as well as sensors
and camera lenses. Never a im t he spray
head at the same point for a long time .
This also applies to cleaning headlights
and paint ed bumpers. Remembe r: the
closer the no zzle is to the surfa ce of the
m at eria l, the gre ater the s tress on the m a­
terial.

cou ld cause the lens to crack.
- Never clean the camera lens wi th abra­
sive products.

238 Checking and filling
the level may be slightly above the "max"
marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
¢ page 232.
To obtain an accurate reading, the engine
must be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System¢
page 16 will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor , we
still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized Audi dealer.
It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
_& WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps. -
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction while ap­
plying light, downward pressure on the
top of the cap .
- To avoid being burned, do not spill anti­ freeze or coolant on the exhaust system
or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire .
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢&. in Working in the engine compart ­
ment on page 230.
.. Turn off the engine .
.. Let the engine cool down.
.. Place a thick rag over the coolant expansion
tank ¢
fig. 192 and carefully twist the cap
counter-clockwise ¢,&. .
.,. Add coolant.
.. Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 23 7, Coolant. We
recommend using only coolant additive G12+
+, G13 or in an emergency G12+. Do
not use a
different additive. In an emergency use plain
water until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible .
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en­
gine becomes hot.
_& WARNING
-= -- The cooling system is under pressure and
can get very hot. Reduce the risk of ..,_

When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea ­
sons, including the installation of replace­ ment or alternate tires or wheels on the vehi ­
cle that prevent the TPMS from function ing
properly . Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.

Using the ABS sensors, the tire pressure moni ­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires . If the pressure decreases in one
or more tires , th is is indicated in the instru­
ment cluster with a warning symbol
RE and a
message¢
fig . 201.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad-
