Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash . For example, using tire-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the s tiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absor bers et c. can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit. Some suspension changes
can, for example, 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 ki nds of
changes may reduce the fo rce levels meas ured by
the sensors and prevent the airbag from deploy­ in g when i t should .
Airbag sys tem
A WARNING ,-
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that
do not have the same pe rformance charac­
teristics as the components o rigina lly ins tal­
led on your vehicle.
- Never use tire-rim combinations t hat have
not been approved by Audi.

_& WARNING
- T urn the engine off.
- Switch the ign ition off .
- Set the parking brake .
- Select the P selector lever pos ition .
- let the engine cool down.
- Never open the hood when there is steam or coolant escaping from the engine compart­
ment, because there is a risk that you could
be burned . Wait until no steam or coolant is
escaping .
- Keep ch ildren away from the engine com­
partment .
- Never spill flu ids on a hot engine. These flu­
ids (such as the anti -freezing agent con ­
ta ined in the coolant) can ignite .
- Avoid short circu its in the electrical system .
- When working in the engine compartment,
remember that the rad iator fan can sw itch
on even if the ignition is switched off, which
increases the risk of in jury .
- Never open the cap on the coolant expan­
sion tank when the eng ine is warm . The
cooling system is under pressure.
- To protect your face, hands, and arms from hot steam or coolant, cove r the cap with a
large cloth when opening.
- Do not remove the engine cover under any circumstances . This increases the risk of
burns.
- If tests need to be performed w ith the en­
gine running, there is additional danger d ue
to moving components (such as the ribbed
322
be lt, alternator and radiator fan) and from
the high-voltage ignition system.
- Do not under any circumstances activate the
throttle inadvertently (for example, by hand
from the engine compartment) if the veh i­
cle is stat ionary but the eng ine is running
and a gear is engaged . Otherwise, the veh i­
cle will start to move immediately and this
could result in an acc ident .
- Pay attent ion to the following warnings
when work on the fue l system is required:
- Do not smoke .
- Never work near open flames .
- Always have a working fire extinguisher
nearby
- All work on the battery or elect rical system
in your vehicle can result in injuries, chemi­
cal b urns, acc idents or burns . Because of
this, all work must be performed
onl y by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk o f electric shock and in ­
jury, never touch the following components
when the engine is running or is being start•
ed:
- Ign ition cable
- Other components in the electronic high -
vo ltage ign ition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake firs t and then se lect
the P selector lever position.
- Always proceed w ith extreme caution so
that clothing, jewelry or long hair do not become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginn ing
work and do not wear clothing that can hang down into the engine .
- Lim it your exposure to exhaust and chemi­
cals to as short a time as possible
