Winter ope rati on
During the winter months, battery capacity tends
to decrease as temperatures drop. This is because
more power is also cons umed w hile starting, and
the headlights, rear window defogger, etc., are used more often.
Avoid unnecessary power consumption, particu­ l arly in city traffic or when traveling only short
distances. Let your authorized Audi dea ler check
the capacity of the vehicle battery before winter sets inc:>
page 198. A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer .
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it will not freeze. This will prevent it
from being damaged and having to be re­
placed.

Be especially careful when working on or near
the battery.
The battery is located in the luggage compart ­
ment under the floor. Before you check anything

tery ac id or any lead particles get on your
skin or clothing. Shield you r eyes . Explosive
gases can cause blindness or other injury.
- Battery acid conta ins sulfuric acid. Sulfuric
acid can cause blindness and severe burns .

tive cables .
- When working on the battery, be s ure not to
short-circuit the terminals wi th tools or oth­
er metal objects . This would cause the bat ­
tery to heat up very quickly, which could lead to damage or exp losion and personal
injury.
- When a battery is charged, it produces hy­
drogen gas which is explos ive and could
cause personal injury.

Starting with jumper
cables
If necessary, the engine con be started by con­
necting it to the battery of another vehicle .
If the engine should fail to start because of a d is­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, us ing a
p air of j umpe r cables to start the engine.
Jump er c abl es
Use only jumper cab les of sufficiently largec ross
sec tion
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use on ly jumper cables with
insulated term inal
clamps which are d istinctly mar ked:

Any of these can cause very ser ious or fatal in­
jury . Fo llow the inst ruct ions be low for safe
hand Ling of your veh icle's battery.
- Always shield your eyes and avoid leaning
over the battery whenever possible.
- A discharged battery can freeze at tempera­
tures just below 32 °F (0 °C). Before con­
nect ing a jumper cab le, you must thaw the
228
frozen battery completely, otherwise it
could explode.
- Do not allow battery acid to contact eyes or
skin. Flush any contacted area with water immed iately.
- Improper use of a booster battery to start a
veh icle may cause an explosion.
- Vehicle batteries generate explosive gases .
Keep sparks, flame and lighted cigarettes
away from batteries.
- Do not try to jump start any vehicle with a
low acid level in the battery.
- The voltage of the booster battery must al­
so have a 12-Volt rat ing . The capacity (Ah)
of the booster battery should not be lower
than that of the discharged battery. Use of batter ies of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury .
- Never charge a frozen battery . Gas trapped
in the ice may cause an explosion .
- Never charge or use a battery that has been
frozen . The battery case may have be weak­
ened .
- Use of batter ies of different voltage or sub­
stantially d ifferent capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery sho uld not be
lowe r than that of the discharged battery.
- Before you check anything in the engine
compartment, always read and heed a ll
