Battery
General information
Your vehicle is equipped with a specia l battery, an AGM battery. This
ba ttery is loca ted in the luggage compar tment and must be
replaced with an original equipment battery. Under normal oper
ating conditions, the battery is
ma inten anc e-free .
Have the battery checked when you take your vehicle in for service .
You a re well advised to replace a battery that is o lder than 5 years .
Disconn ecting th e batt ery te rmin als
Some vehicle functions (power w indow regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected again. To prevent this, the battery should only be disconnected from the
vehic le electrical sys tem when abso lutely necessary for repairs .
Vehi cles not dri ven for lo ng p eriods
If you are going to let your vehic le stand for a long time and n ot
drive it, you should remember there are e lectrica l components
whic h are still functioning and they will draw energy from the
battery and drain it, for example, the engine immobilizer. To prevent
t his, you can eithe r charge the batte ry occasionally to keep it in
good working condition or you can disconnect the negative cable
on the battery.
W int er op erati on
During the winter months, batte ry capacity tends to decrease as
temperatures drop . This is because more power is also consumed
whi le starting, and the headlights, rear window defogger, etc ., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when trave ling o nly short distances . Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
~ page 232. A we ll charged battery will not only preven t starting
problems when the weather is cold, but will also last longer.
Repla cing batter y
The new battery must hav e the same capacity, voltage ( 12 volts),
amperage, construction and p lug sea ling, as the orig inal battery .
Specifications are listed on the battery housing. Batteries specia lly
developed by Aud i fulfill the main tenance, output, and safe ty
requirements. ...,

& WARNING (continued)
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
on driver's side 8-pillar.
The recommended tire pressures are on the tire pressure label and
in the table=>
page 238, "Cold tire inflation pressure". This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inflation
pressure" recommendations =>
page 238. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures for the new, original equipment tires that were
on your vehicle at the time it was manufactured . For the location of
the label =>
page 238, fig. 148.
Most tires lose air naturally over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not
possible to see whether the radial tires used today are underinflated
just by looking at them. Therefore,
be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long." See=>
page 242, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire. If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with the edge of the tire
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 difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle.
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label
located on driver's side 8-pillar.
• Turn the valve stem cap counter -clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve.
• The tire pressures should only be checked and adjusted when
the tires are cold. The slightly raised pressures of warm tires must
not be reduced.
• Adjust the tire pressure to the load you are carrying.
• Reinstall the valve stem cap on the valve.

& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed . Always know the maximum speed
before driving off . Never drive faster than the speed permitted for
your specific winter tires . This will cause damage to the tires
leading to an accident and serious personal injury to you and your
passengers .
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , loss of control , crashes and serious

personal injuries . Have worn or damaged tires replaced immed i
ately.
• Winter tires have maximum speed rating that may be lower
than your vehicle' s maximum speed.
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated .
& WARNING
Always adjust your driving to the road and traffi c conditions .
Never let the good acceleration of the winter tires and all -wheel
drive tempt you into taking extra risks. Always remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions .
