2018 AUDI Q7 wheel

Airbag syste m
airbag inflates -even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof .
- Always install rear-facing child safety seats
on the rear seat .
- If you must install a rearward-fac ing child
safety seat on the front passenger seat be­
cause of exceptional circumstances and the
PASSENGER AIR BAG OFF~; light does not
come on and stay on, immed iate ly install
the rear-fac ing ch ild safety seat in a rear
seat ing pos ition and have the airbag system
inspected by your a uthorized Audi dea ler.
A WARNING
Objects between you and the a irbag w ill in ­
crease the risk of inj ury in a crash by interfer­
ing with the way the airbag unfo lds or by be­
ing pushed into you as the a irbag inflates.
- Never hold things in your hands or on your
lap when the vehicle is in use.
- Never transport items on or in the area of
the front passenger seat . Objects could
move into the area of the front airbags dur­
ing brak ing or other sudden maneuvers and
become dangerous projectiles that can
cause serious personal injury if the a irbags
inflate .
- Never place or attach accessor ies or other
objects (such as cupholders, telephone
brackets, large, heavy o r bulky objects) on
the doors, over or nea r the area marked
"AIRBAG" on the steering wheel, instru­
ment pane l, sea t backrests or between
those areas and yoursel f. These objects
could cause injury in a crash, especially
when the airbags inflate.
- Never recline the front passenger's seat to
transport objects . Items can also move into
the area of the side airbag o r the front a ir­
bag dur ing braking or in a sudden maneu­
ver. Objects near the airbags can become
280
-
pro jecti les and cause injury, part icularly
when the seat is reclined.
- Never p lace or transport objects on the
front passenger seat. Objects on the front passenger seat could cause the capacitive
sensor in the seat to signal to airbag system
that the seat is occupied by a person when it
in fact is not, or that the pe rson on the seat
is heavie r than he or she act ually is . The
change in elec tric capa citan ce beca use of
such o bje cts can c ause the p assenge r front
airbag to be turned on when it should be
off, or can cause the airbag to work in a way
that is different from the way it would have
wo rked without objects on the seat.
- Always make sure that there is nothing on
the front passenge r seat that will cause the
capacitive passenge r detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not , or to signal that it is occupied by some­
one who is heavier than the person act ually
sitt ing on the seat. The presence of an ob­
ject could ca use the passenger front air bag
to be turned on when it should be off, or
could cause the airbag to work in a way that
is different from the way it would have
worked without the object on the seat.
A WARNING
The fine dust created when airbags deploy can
cause breathing prob lems for people with a
h istory of asthma or other breath ing cond i­
tions .
- To reduce the r isk of breathing p roblems,
those with asthma or other respiratory con­
ditions should get fresh a ir right away by
getting out of the vehicle or opening win­
dows or doors .
- If you are in a collision in which airbags de­
ploy, wash your hands and face with m ild
soap and water before eating.
- Be ca refu l not to get the dust into your eyes,
or into any cuts or scratches.
- If the residue should get into your eyes,
flush them w ith wate r.

Airbag syste m
Make sure that the PASSENGER AIR B AG
OFF ,;;
light comes on and stays on all the
t ime whenever the ignition is switched on.
A WARNING
- If the PASS ENGER AIR B AG O FF 1'i; light
does not go out when an adult is sitting on
the front passenger seat after tak ing the
steps described above, make sure the adult
is p roperly seated and restrained at one of
the rear seating positions.
- Have the airbag system inspected by your
authorized Aud i dealer before transporting
anyone on the front passenger seat.
(D Tips
If the capacitive passenger detection system
determines that the front passenger seat is
empty, the frontal airbag on the passenge r
side w ill be tu rned off, and the
PA SSENGER
AIR BAG OFF
1'i ; light will stay on.

Repair, care and disposal of the airbags
Parts of the airbag system are installed at many
different places on your Audi. Installing, remov ­
ing, servic ing or repa iring a part in an area of the
veh icle can damage a part of an airbag system
and prevent that system from working properly
in a collision .
There are some important things you have to
know to make sure that the effectiveness of the
system w ill not be impaired and that discarded
components do not cause injury or pollute the
env ironment.
A WARNING
Improper care, serv icing and repai r proce­
dures can increase the r is k of personal injury
and death by preventing an airbag from de­
ploying when needed or dep loying an airbag
unexpectedly:
-
- Never cover, obstruct, or change the steer ­
ing wheel horn pad or airbag cover or the in­
strument pane l or modify them in any way.
284
- Never attach any objects such as cupholders
or telephone mountings to the surfaces cov­
ering the a irbag un its.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one mois­
tened w ith plain water. Solvents or cleaners
could damage the airbag cover or change
the st iffness or strength of the material so
that the airbag cannot deploy and protect
properly.
- Never repair, adjust, or change any parts of
the airbag system.
- All work on the steering wheel, instrument
panel, front seats or e lectr ica l system ( in­
cluding the installation of a udio eq uipment,
cellular telephones and CB radios, etc.) m ust be performed by a qualified techn ician
who has the training and specia l equipment
necessary.
- For any work on the airbag system, we strong ly recommend that you see your au­
thorized Audi dealer or qualified workshop.
- Never modify the front b umper or parts of
the vehicle body.
- Always make sure that the side a irbag can
inflate without interference:
- Never install seat covers or replacement
upholstery over the front seatbacks that
have not been specifically approved by
A udi.
- Never use additional seat c ushions that
cover the areas where the side airbags in­
flate.
- Damage to the orig inal seat cove rs or to
the seam in the area of the s ide airbag
module mus t always be repaired immedi­
ate ly by an autho rized Aud i dealer .
- The a irbag sys tem can deploy on ly once. Af­
ter an airbag has been deployed, it m ust be
replaced with new replacement parts de­
signed and approved especia lly for your
Audi model version . Replacement of com­
plete airbag systems or airbag components
must be performed by qua lified workshops
only . Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Ma intenance booklet under AIRBAG RE-
PLAC EMENT RECORD.

General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob ­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
~Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
~Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom­
mends using winter tires dur­
ing the winter months . Low
temperatures significantly de­
crease the elasticity of summ­
er tires, which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
t ions. The surface of the r ims
does not have sufficient corro­
sion protection for this and
could be permanently dam ­
aged by road salt or similar
substances.
