A discharged battery can fre eze at temperatures
of only 32 F
0 (0 °C). A llow a frozen battery to
thaw comp lete ly before attempt ing to charge it
¢ ,&. However, we recommend not using a
thawed battery again because the battery casing
can be cracked due to ice formation and can leak
battery acid.
Battery chargin g (Ma ximum cha rging rate of
30 amp s/14 .8 Volt )
When charging at low voltages (e.g. with a trick
le cha rger ),
the battery cables do not have to be
d isconnected first. The battery caps should
not
be opened when charging a battery .
It is not necessary to remove the battery from
the luggage compartment, and it is also not nec
essary to disconnect the cables.
Check ing and Filling
Fast charging the batt ery (charging rate
ab ove 14.8 Volt )
For technical reasons do not use a battery charg
er that uses vo ltage greater than 14.8 Volt to
charge your vehicle's battery.
A WARNING
=
Charging a battery can be dangerous .
-Always follow the operating instructions
provided by the battery charger manufactur
er when charging your battery .
- Never charge a frozen battery. It may ex
plode because of gas trapped in the ice. Al
low a froze n battery to thaw out first .
- Do not reuse batter ies which were frozen.
The battery hous ing may have cracked and
weakened when the battery froze .
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark. Do not smoke . Hydrogen gas generat
ed by the battery is explos ive.
- To reduce the danger of explosion, never connect or d isconnect charge r cables while
the charger is ope rating .
- Fast charg ing a battery is dangerous and
should only be attempted by a competent
technicia n w ith the prope r equipment.
- Batte ry acid that may spill during charging
should be washed off w ith a so lution of
warm water and baking soda to neutra lize
t he acid .
{[) Note
Never use a fast charger as a booster to start
the e ngine. This will se riously damage sensi
tive electronic components, such as control
units, re lays, radio, etc., as well as the bat tery
charge r.

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
tio tires. These tires have been thoroughly tested
and been selected specifically for your model fo r
thei r supe rb perfo rmance, road feel and handling
unde r a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re de tails.
The low aspect ratio of these t ires is indicated by
a nume ra l of
55 or less in the tire's size desig na
tion . The nume ra l rep resents the rat io of t he
tire 's sidewall he igh t in relat io n t o it s tread w idth
e xpresse d in percen tage. Convention al ti res have
a height/w idth ratio o f 60 o r more .
The performance of low -aspect-ratio tires is par
ticularly sensitive to improper inflation pres
sure. It is therefore important that low a spect
ratio tires are inflated to the specified pre ssure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
be checked at le ast once a month and alwa ys
before a long trip¢
page 228.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, curbs, gullies or
ridges on the road, pa rt icu la rly if the t ire is un
de rinflated.
In order to minimize the occurrence of impact
damage to the t ires of your ve hicle, we recom
mend that you observe the fo llow ing precau
tions:
- Always maintain recommended inflation pres
su res . Check your tire pressure every 2,000
miles (3,000 km) and add air if necessary .
- Drive caref ully on roads with potho les, deep
gul lies or r idges . The impact from drivi ng
through or over s uch obstacles can damage
you r tires. Im pact with a cu rb may also cause
damage to you r tires .
234
-After any impact, immed iate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire as
soon as possible.
- Ins pect your tires every 2,000 mi les (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
underinfla tion, w hich could even tua lly cause
tire fa ilure . If yo u be lieve that a tire may have
been damaged, replace the tire as soon as pos
sible.
- These tires may wear mo re quickly than others .
- Please also remember that, while t hese tires
delive r responsive hand ling, they may ride less
comforta bly and make mo re noise than o ther
choi ces.
