162 Airbag system
www .dtsc.ca.gov/hazardouswaste/per ­
chlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts wit h pretens ioners are
scrapped, all applicable laws and regula­
tions must be observed. Your authorized
Aud i dea ler is familiar wit h these requ ire­
ments and we recommend that you have
your dea le r perfo rm this se rv ice for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-r im combinations not approved by Aud i,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion st ruts, shock absorbers etc. can change
the forces that are measured by the a irbag
sensors and se nt to the electron ic control
un it. Some suspension changes can, for exam­
p le, increase the force levels meas ured by the
sensors and make the airbag system deploy in
crashes in which it would not deploy if the
changes had not been made. Other kinds of
changes may reduce the force levels meas­ ured by the sensors and prevent the a irbag
from deploying when it should.
A WARNING
Changing the vehicle's suspension includ­
ing use of unapproved tire -rim combina­
tions can change Advan ced A irbag per­
formance and increase the risk of serio us
personal in jury in a crash.
- Never install suspension components
that do not have the same performance character istics as the components origi­
nally installed on your vehicle.
- Never use tire-rim combinatio ns that
have not been approved by A udi.
Knee airbags
Description of knee airbags
Applies to vehicles: with knee airbags
The knee airbag system can provide supple­
mental protection to properly restrained
front seat occupants.
F ig . 1 61 Driver's knee airbag
The driver knee airbag is in the ins trumen t
pane l underneath t he steering wheel
¢ fig. 161, the airbag for the passenger is at
about the same height in the instrument pan­
el underneat h the glove compartment.
T he knee airbag offe rs additional p rotection
to the driver 's and passenger's knees and up­
per and lower th igh areas and supplements
the protection provided by the safety belts.
If t he front airbags dep loy , the knee ai rbags
also dep loy in frontal coll isions when the de­
ployment threshold stored in the contro l unit
is met
<=> page 155, More important things to
know about front airbags.
In addition to their norma l safety function,
safety belts help keep the dr iver or front pas­
senger in position in a fronta l collision so that
the a irbags can provide supplemental protec­
t ion .
The airbag system is not a substit ute for your
safety belt. Rather, it is part of the overa ll oc­
cupant restra int system in your vehicle. Al­
ways remember that the a irbag system can
o nly help to protect you if you are weari ng
your safety belt and wea ring i t properly. This
is why you should always wear your safety
belt, not just beca use the law requi res you to
do so

Avoid damaging the
vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that
low-lying parts such as spoilers and exhaust
system parts do not bottom out and get dam­
aged.
This is especially true for vehicles with low­
slung chassis (sports chassis) * and fully load­
ed veh icles.
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- T he water must not be any h igher than the
bottom of the veh icle body.
- Do not d rive faster than wa lking speed.
..&, WARNING
After driving through wate r, m ud, slush,
etc., the brakes may be slow to take effect
because o f wet brake rotors and pads . Dry
the brakes first by braking carefully to re­
store the full braking effect.
(D Note
- Vehicle components such as the eng ine,
transmission, suspension or e lectrical
system can be severely damaged by driv­
ing thro ugh water.
- Always switch
off the Start-Stop-System
when driving through water¢
page 79 .
@ Tips
-Check the depth o f the wate r before driv ­
ing through it.
- Do not s top the veh icle, dr ive i n reverse
or switc h the engine off when driving
through water.
- Keep in mind that oncom ing vehicles
may create waves that raise the water
l eve l and make it too deep for you r vehi­
cle to drive through safely .
-
Dri vin g and en vironm ent 201
- Avo id driving through salt wate r because
it can cause corrosion .
Catalytic converter
Applies to vehicles: w ith gasoline engine
It is very important that your emission con­
trol system (catalytic converter) is function­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
... Always use lead-free gasoline ¢ page 214,
Fuel supply.
... Never run the tank down all the way to emp­
ty.
.,. Never put too much motor o il in your engine
¢ page 226, Adding engine oil~-
... Never try to push- or tow-sta rt your vehicle.
The catalytic converter is an efficient "clean­
up" dev ice bui lt into the exhaust system of
the ve hicle. The cata lytic conve rter bu rns
many of the pollutants in the exha ust gas be­
fore they are re leased into the atmosphere .
The exclusive use of unleaded fuel is c ritically
important for the life of the ca talyt ic convert­
er and proper f unct ion ing of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after s topping
the engine.
- Never touch the exhaust tail pipes once
they have become hot . This cou ld result
in burns .
- Do not park or operate the vehicle in
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material which can
cause a fire.
- Do not apply additional undercoating or
rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driv ing, the
substance used fo r undercoating could
overheat and cause a fire.

Always apply brakes early. When driving
downhill, shift into a lower gear to use the en­
g ine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Air suspension*
When driving with a trai ler, activate the trailer
mode of the air suspension. Switch the air
suspension trailer mode on when you are tow­
ing a trailer. This will limit the regulation by
the air suspension while driving. Select in the
MMI:
! CARI function button> (C ar) * systems
control button > Vehicle settings > Air susp.:
towing > On .
Coolant temperature
The coolant temperature gauge¢ page 11
must be observed carefully. The coolant tem­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds . Re­
duce your speed immed iately if the LEDs in
the top pa rt of the display turn on.
For more information about indicator lights,
refer to. ¢
page 16 .
A WARNING
Anyone no t properly restrained in a mov­
ing veh icle is at a much greater ris k in an
accident . Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi .
Trailer towing tips
Important to know
Your vehicle handles differently when tow ing
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform­
ance and economy w ill greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
M N turning, stopping and backing up in an area 0
~ away from traffic. Keep practicing until you
~ have become comp lete ly fam iliar with the way 1.1'1 ,...., 1.1'1 ,....,
Trailer towing 207
your vehicle-trai ler combination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a trailer generally req uires
steering action opposite to that when backing
up your vehicle without a trai ler.
Maintain a greater distance between your ve­
hicle and the one in front of you. You will need
more room to stop. To compensate for the
trailer , you wi ll need a larger than normal
turning rad ius.
When passing, remember that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your trailer before chang­
ing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 292.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only after doing the fol­ lowing:
When parking:
.,. App ly the foot brake .
.,. Have someone p lace chocks under both the
vehicle and the trailer wheels.
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load .
.,. Turn the wheels towards the curb.
.,. Apply the parking brake .
.,. Select the P selector lever posit ion.
When re starting after parking:
.,. App ly the foot brake.
.,. Start the engine.

sonal injuries . Have worn or damaged tires
replaced immediate ly.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed.
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10,5 mm), including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
q(D _ For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
Tires and wheels 265
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes . Always make sure to follow the in­
structions provided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
([) Note
-Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered. Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the vehicle.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all-wheel drive.

Whenever you hov e your vehicle transported,
be sure to note the following :
(D Note
Mount the tie-down chains/cables over the
running surface (circumference) of the
tires. Never secure the vehicle by the axle,
the suspension struts or the front or rear
towline eye . For technical reasons, the
pressure in the suspension struts may
change du ring the transport and this will
