During the winter months, battery capacity
tends to decrease as temperatures drop. This
i s because more power is also consumed while
start ing, and the headlights, rear window de
fogger, etc., are used more often .
Avoid unnecessary power consumption, par
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi

Replacing battery
The new battery must have the same capaci
ty, vo ltage ( 12 volts), amperage, cons truction
and p lug sealing, as the origina l ba tte ry. Spec
if ications are listed on the batte ry housing.
Batteries specially developed by A udi fulfill
the maintenance, output, and safety require
ments.
When insta lling the battery, make sure the ig

forget the spare tire. If the press ure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the t ire
gauge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do .
If the pressure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure you need and add the a ir
that you need to reach the correct pressure for
the veh icle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your ve hicle and in this manua l and the kind
of dr iving you p lan to do .
Never exce ed the ma ximum inflation pres

Remember that the vehicle manufacturer , not
the t ire manufacturer , determ ines the correct
tire pressure for the tires on your veh icle .
It is important to check the tire pressure when
the t ires a re cold .
- Read the req uired tire press ure from the tire
pressure label located on driver's s ide B-pil
l ar .
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressure ga uge on the valve.
- The tire pressures sho uld on ly be checked
and adjusted when the tires are cold . The
s light ly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the tire pressure?
The correct tire pressure is espec ially impo r
tant at high speeds . The pressure sho uld
therefore be checked at least once a month
and a lways befo re starting a journey.
When should I adjust the tire pressures?
Adj ust the tire pressu re to the load you are

Handling characteristics change when
driving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characteristics by pu lling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance .
A low pressure or flat
rear tire also affects
driving character istics by pulling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
A WARNING
Changed vehicle handling character istics
when driving in the run -f lat mode can
cause loss of vehicle contro l, a crash and
serious personal injury.
- Driving on special run-flat tires in the
run-f lat mode wi ll change vehicle han
dling characteristics during braking,
when cornering and under heavy acceler
ation.
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run -flat mode.
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf
fic laws.
Q) Note
We always recommend driving w ith even
more care when using these special t ires in
the run-flat mode . Always avo id sudden
