Checking and Filling
-If you get batt ery acid in your eyes or on
your skin, immediately rinse with cold wa
ter for several minutes and get medical at
tention .
- If you should ingest any battery acid, seek
medical attention immediately.
- Do not expose the battery to an open flame, electric sparks or an open light .
- Do not smoke.
- Do not interchange the positive and nega-
tive cables.
- When working on the battery, be sure not to short-circuit the terminals with tools or oth
er metal objects. This would cause the bat
tery to heat up very quickly, which could lead to damage or explosion and personal
injury.
- When a battery is charged, it produces hy
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys
tem, disconnect the nega tive ground cable .
- Before performing any work on the electri cal system, switch off the engine and igni
tion as well as any electrical equipment. The negative cable on the battery must be dis
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights.
- Before disconnecting the battery, sw itch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off.
Reconnect the positive cable first and then
the negative cable. Never interchange the
cabl es - this could start a fire!
- Never charge a frozen or a thawed-out bat
tery . It could explode! If a battery has fro
zen, then it must be replaced. A discharged
battery can freeze over at 32°F (0°C).
- Make sure the vent hose is always attached
to the opening on the side of the battery.
202
- Never use batteries which are damaged .
There is the danger of an explosion! Always
replace a damaged battery.
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related acces
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive problems.
Wash hands after handling .
(D Note
- Do not disconnect the vehicle battery when
the ignition is switched on or when the en
gine is running, otherwise, you will damage
electronic components in the electrical sys
tem .
-If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing" , otherwise it
will be damaged and will then have to be re
placed.
Battery charging
Starting the engine requires a well charged bat tery .

Wheels and Tires
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.
.,.M ark 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.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom
mends using winter tires dur
ing the winter months. Low
temperatures significantly de crease the elasticity of summ
er tires, which affects traction
Wheels
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
tions. The surface of the rims
does not have sufficient corro
sion protection for this and
could be permanently dam aged by road salt or similar
substances.

A WARNING
-
-You o r your passengers could be in jured
while changing a wheel if you do not follow
these safety precautions :
- Position the vehicle jack only at the des ig
na ted lift ing po ints and alig n the jack.
Otherwise, the veh icle jack could slip and
cause an injury if it does not have suffi
cient hold on the vehicle.
- A soft or unstab le surface under the jac k
may cause the vehicle to slip off the jack.
Always provide a firm base for the jack on
the ground. If necessary, use a sturdy board under the jack .
- On hard, slippery surface (s uch as tiles)
use a rubber mat or similar to prevent the
j ack from slipping.
- To help prevent in jury to yourse lf and your
passengers:
- Do not raise the ve hicle until you are sure
the jack is securely engaged.
- Passengers must not remai n in the vehicle

Emergency assistance
-Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traff ic.
- Make sure jack position is correct, adjust
as necessary and then cont inue to raise

(D Note
Do not lift the vehicle by the sill. Position the
vehicle jack only at the designated lifting points on the sill. Otherwise, your vehicle will
be damaged.
Taking the wheel off /installing the spare
tire
Follow these instructions step-by-step for chang
ing the wheel .
Fig. 179 Changing a wheel: using the screwdriver handl e
(with the blade removed) to turn the bolts
Fig. 180 Changing a wheel: alignment pin insid e the top
hole
After you have loosened all wheel bolts and raised the vehicle off the ground, remove and re
place the whee l as follows:
Removing the wheel
• Remove the topmost wheel bolt comp letely
with the
hexagonal socket in the screwdriver
230
handle (vehicle tool kit) ¢ fig. 179 and set it
aside on a
clean surface.
• Screw the threaded end of the
alignment pin
from the tool kit hand-tight into the empty bolt
hole ¢
fig. 180.
• Then remove the other wheel bolts as described
above.
• Takeoff the whee l leaving the alignment pin in
the bolt hole¢ (!).
Putting on the spare tire
• Push the spare tire over the alignment pin.
• Screw on the wheel bolts and tighten them
slightly using the hexagonal socket.
• Remove the alignment pin and insert and t ight
en the remaining wheel bolt slightly like the
rest.
• Tur n the jack hand le counter-clockw ise to lower
the vehicle until the jack is fully released.
• Use the wheel bolt wrench to tighten a ll wheel
bolts firmly ¢
page 228. Tighten them in a
crisscross pattern,
from one bolt to the (ap
proximately) opposite one, to keep the wheel
centered.
• Perform the steps required after chang ing the
wheel¢
page 227, A~er changing a wheel.
The hexagonal socket makes it easier to remove
the wheel bo lts from the rim . Care should be tak
en when removing the reversible blade.
(D Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor . Work carefully and have a second per
son to help you.
(D Tips
-When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 231.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be
fore remounting the wheel.
