Child safety
-Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a
passenger front and side airbag.
- Never put the forward-facing child restraint
up, aga inst or very near the instrument pan­
el.
- Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possible before installing the for­
ward-fac ing child restraint. The backrest
must be adjusted to an upright posit ion.

PASSENGER AIR BAG
OFF
light comes on and stays on all the time
whenever the ignition is switched on.
_&. WARNING
Rearward-fac ing ch ild restra ints:
- A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates -even with an Ad ­
vanced Airbag System .
- T he inflating airbag wil l hit the child safety
seat or infant carrier with great force and
will smash the chi ld safety seat and child
against the backrest, center armrest, door
or roof.
- Always be especially carefu l if you must in­
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir­
cumstances.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the t ime
whenever the ignition is switched on .

belt pat h
c::> ,&..
.. Push the ch ild safety seat down with your full
weight to get the safety belt really tight.
.. Insert the belt tongue into the buckle for that
seating position.
.. Guide the safety be lt back into the retractor un­
til the belt lies flat and snug on the ch ild safety
seat.
.. You should hear a "clicking" noise as the belt
w inds back into the inertia reel. Test the con­
vert ible lock ing retractor by pulling on the belt .
You should no longer be able to pull the belt
out of the ret ractor. The convertible locking re­
tractor is now activated .

properly tight and fastened so that the seat
cannot move forward or s ideways more than
one inch (2 .5 cm).
_&. WARNING
Using the wrong child restraint or an improp­
erly installed child restraint can cause serious
personal injury or death in a crash.
- Always make sure that the safety belt re­
tractor is loc ked when insta lling a child safe­
ty seat. An unlocked safety belt retractor
cannot hold the child safety seat in place
during normal driving or in a crash.
- Always buckle the child safety seat firmly in
place even if a chi ld is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or in a crash.

LATCH system (Lower
anchorages and tethers
for children)
Child Restraint System anchors and how
are they related to child safety
T o provide a simpler and more practicable way to
attach the ch ild restra int on the veh icle seat, Fed ­
eral regulations require special lower anchorages
in vehicles a nd devices on new child restraints to
attach to the vehicle anchorages .
The combination of the tether anchorages and
the lower anchorages is now generally ca lled the
LATCH system f or " Lower Anchorages and
T ethers for Child ren ."
Forward -facing chi ld restraints manufactured af ­
ter September 1, 1999, are requ ired by U.S. fed­
eral regulations to comp ly w ith new ch ild head
movement performance requ irements . These
new pe rformance requ irements make a te ther
necessary on most new ch ild seats .
Installing a ch ild restra int that requires a top
tethe r without one can seriously impair the per­
fo rmance of the child restra int and its ability to
protect the ch ild in a co llision . Installing a ch ild
r est rain t that requ ires a top te ther w it h out t he
top tether m ay be a vio lation o f st ate l aw .
Child rest raint manufacturers offer LA T CH lower
anchorages on the ir chil d seats with hook-o n or
push-on connec tors attached to adjustab le
str aps.
In add ition to the LATCH lower anchorages, these
c hi ld restra int systems usually requ ire the use of
te the r straps to he lp keep the c hild restra int
firmly in pla ce. .,..

A WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
w ith the engine hot. There is a risk of burns .
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coo lant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the e x­
haust system or hot engine components.
The ethy lene glycol in engine coola nt can
catch fire under certa in circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the o riginal container
away from ch ildren . The re is a risk of poison­
ing .
- W hen working in the engine compartment,
remember that the rad iator fa n can switch
on ev en if the ignition is switched off, wh ich
increases the risk of pe rsonal injury.
@ Note
Do not add coolant if the expans ion tank is
empty . Air cou ld enter the cooling system and
damage the eng ine. If this is the case, do not
continue driving. See an author ized Audi deal ­
er or a uth ori zed Audi Service Facility for a ssis­
ta nce .

Battery
General information
The battery in yo ur Audi does not need any ma in­
tenance under normal operating conditions. Aud i
recommends having the electro lyte level check by
an author ized Audi dealer or author ized Audi
Service Fac ility when the re a re
high outside tem­
pe ratu res or when dr iv ing a ll day. The electroly te
leve l sho uld also be checked ea ch t ime the bat ­
t ery is charged
9 page 210 .
Have the battery checked when you br ing you r ve­
hicle in fo r an inspec tio n. It is a good idea to re­
p la ce the batte ry if i t is more than 5 ye ars old .
During certai n types of a irbag dep loyments, the
battery is disconnect ed from the vehicle electr i­
cal system fo r safety reasons
9 .&. in Repair, care
and disposal of the airbags on page 163.
Disconnecting the battery terminals
Some veh icle functions (such as power windows)
are not ava ilable when the batte ry is disco nnect­
ed. These functions must be programmed after
the ba ttery is reconnec ted. To avoid havi ng to do
t his , on ly disconnect the b attery from the veh icle

Winter operation Du ring the winter months , it is common for the
batte ry capaci ty to dec rease as the tempe rat ur es
become lower . This is because more powe r is
needed to start the vehicle and componen ts such
as the he ad lights and the rear window defogger
are used more frequent ly.
Avoid using powe r unnecessar ily, especially in

Tires and wheel s
-Always adapt your driving to the road and
traff ic conditions. Dr ive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose tract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow a nd ice. Summer
tires cause less road noise, tire wear and fuel
consumptio n.
(D Tips
You can also use all season tires instead of
w inte r tires. Please note that in some coun­
t ries w here winter tires are requ ired, on ly win­
t er tire s wi th the .& symbol may be pe rm it­
t ed.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
Th is applies also to veh icles with all wheel
drive* .
.,. Ch eck and correct the seating of th e snow
c h ains if necessa ry afte r dri ving a few feet. Fo l­
l ow the ins tructions from the manuf acturer.
.,. Note t he max imum permit ted speed w hen driv ­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
Snow chains not only improve the
driving in win ­
ter road conditions, but a lso t he
braking .
Use of s now chai ns is o nly pe rm itted with certa in
r im/t ire comb ina tion s due to techn ica l reason s.
Chec k w ith an au thori zed A udi d ealer or au tho r­
ized A udi Service Facility to see if yo u may use
snow cha ins.
Use
fine -mesh snow chain s. They mus t not add
mo re th an 0 .5 3 inch ( 13.S mm) in height, in clu d­
ing the chain lock.
You must remove the chai ns when dr iv ing on
roads tha t are
free of snow. W hen r oads are free
of snow, snow chains can imp air handling an d

damage the tires, and the chains wi ll quick ly be
dest royed.
A WARNING
Using incorrect snow chains o r insta lling snow
cha ins incor rectly can res ult in loss of veh icle
c o ntrol, which increases the risk of an acc i­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the c hains come into direct c on­
tact with them. Remove the wheel covers*
first . Use coa ted snow cha ins.
