Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increasingly more and more diffi
cu lt to replace vehicle light bulbs since in many
cases, other parts of the car must first be re
moved before you are able to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must be
correctly taken apa rt and then properly put back
together to help prevent breakage of parts and

10. With the engines running, remove the cables
i n
reverse order of the way they were instal
l ed. Make sure the cables do not get caught
in mov ing engine components.
11. Sw itch the heater fan and rear w indow de-
froster off.
12. C lose the battery cover .
The battery is vented to the outside so that gases
do not enter the passenger compartment. Make
sure that the connected positive termina l clamps
on the jump start cab le have sufficient contact
with metal.
A WARNING
Follow the warnings and instructions from
the jump start cab le manufacturer to reduce
the risk of ser ious injuries and vehicle dam
age. If you are unsure about anything, call
roads ide ass istance.
- The jump start cables must be long enough
so that the veh icles do not touch.

ment
~page 316.
(D Note
Connecting jump start cables incorrectly can
damage the alternator .
- Always connect the positive terminal(+) to
the positive term inal(+) and the negative
term inal(-) to the negat ive terminal(-) on
the body ground po int, but not the negative
terminal on the battery.
- Make su re the screw plugs on the battery
cells are installed securely. If not, tighten
the plugs before connecting the clamps to
