2013 AUDI A4 light

(D Note
Never use a fast charger as a booster to
start the engine . This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc ., as well
as the battery charger .
Battery replacement
The new battery mu st have the same specifi­
cations and dimensions as the original equip­
ment battery .
Intelligent energy management in your vehi­
cle is responsible for d istributing the electr i­
cal energy throughout your vehicle
c::>
page 192. The intelligent energy manage­
ment system w ill keep the engine battery
charged bette r then vehicles w ithout t his sys­
tem. To make sure the additional electr ica l en­
ergy is available once again after you have
changed the battery, we recommend that you
install batteries of the same type and manu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the bat tery hous ing. Your
author ized Audi dealer must code the battery
in the energy management system to enable
you to use the energy management functions
correctly after replac ing the battery .
If it is not possible to use a battery of this
type, the new battery must have the same ca­
pac ity, voltage (12-volts), amperage, con­
struction and plug sea ling.
When insta lling the battery, make sure the ig ­
nition and all electr ical consumers are turned
off.
(D Note
Make sure the venti lation hose on the s ide
of the battery is connected , othe rwise
fumes or battery ac id can leak out .
@ For the sake of the environment
Because of the problem of proper d isposal
of a battery, we recommend your author­
ized Aud i dealer change the battery for
Checkin g and fillin g 233
you. Batteries contain sul fur ic acid and
l ead and must always be disposed of prop­
erly in comp liance with a ll environmental
regulations. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ronment .

-Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­ lar .
The recommended t ire pressures are on the
tire pressure label and in the table
c:> page 238, Cold tire inflation pressure .Th is
means that the pressure must be checked and
adjusted when the tire has not been driven for
mo re tha n a couple of m iles (k ilome ters) at
l ow speeds during t he p revious three hours.
A ir in the tires expands when the ti re heats up
as a result of inte rna l friction as it flexes in
use. The tire press ure is higher when the tire
has warmed up than when it is "cold."
It is the i nflat ion p ressu re in a "cold" tire that
counts . Therefore, you shou ld never let air ou t
of a warm tire to match "Cold tire inflation pressure" recommendations
c:> page 238. The
tires would then be under inflated and could
fa il suddenly.
The tire press ure labe l on yo ur Audi lists the
recommended cold t ire inflat ion pressures at
maximum capacity for the new, origina l
equ ipment tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the label
<=> page 238, fig . 191 .
Most tires lose a ir naturally over time. They
can also lose some a ir if you drive
over a pot­
hole or hit a curb while parking. It is usually
not possible to see whether the radial t ires
used today are underi nflated just by looking
at them.
Therefore, be sure to check tire pressures at
least o nce a month and always before going
on a long tr ip . Make sure to take the number
of people and the amoun t of luggage into ac­
coun t when adjusting tire pressure for a t rip -
even one that you would not consider to be
Tire s an d wheel s 241
"long." See c:> page 24 2, Tires and vehicle
load limits
for more important information.
A lways use an acc urat e tire pressu re ga uge
when checking and ad justing infla tion pres ­
s ur es . Check a ll of the tires and be sure not to
forget the spare tire. If the pressure in any t ire
is too h igh when the tire is "cold", let a ir o ut
of the t ire s low ly w ith 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 k ind of
driv ing you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the co ld
t ire a nd the pressure you need and add the air
that you need to reach the correct pressure for
t h e ve hicl e load (passenge rs and luggage) for
the tires on you r veh icle as l isted on the o n
yo ur vehicle and in this ma nual and the kind
of driving you plan to do.
Never exc eed the maximum inflation pr es­
sure li ste d on the tire sidewall for any re a­
s o n.
Remember that the vehicl e manufacture r, not
t h e tire manu fact urer, de termines t he cor re ct
t ir e p ress ure fo r th e tires on your ve hicl e.
It is important to check the t ire p ressu re whe n
the tires are co ld.
- Read the required tire pressure from the t ire
pressure labe l. The t ire pressure label is lo­
cated o n the dr iver's side 8-pillar. The tire
pressure labe l lists the recommended co ld
tire inflation pressures for t he vehi cle at its
maxim um capacity weigh t and t he tires that
were on your ve hicle a t the time i t was man­
ufactured . For recommended tire pressures
for normal load conditions, p lease see chap­
ter
<=> page 238.
-Tu rn the va lve stem cap counter -clockwise
to remove it from the tire
va lve .
-Place t he ai r pressure gauge on the va lve.
- The tire pressu res should o nly be checked
and ad justed when the tires are co ld . The
slightly raised pressures of warm tires must
not be red uced.

A WARNING
- If the tire pressure indicator appears in
the instrument cl uster display, one or
more of your tires is significantly under­
inflated. Reduce your speed immediately
and avoid any hard stee ring or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pres sure to the proper p res­
s u re as in dic ated on the vehicle 's t ire
pressure label ¢
page 238. Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cato r may be delayed .
-Ask your authorized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with

• Install the rod on the vehicle jack: Insert
the rod into the opening on the handwheel.
Turn the rod left or right to secure it .
• Continue ra is ing the jack with the rod until
the wheel lifts off the ground slightly.
Position the vehicle jack
onl y under the desig­
nated lifting points on the sill
c:> fig . 205 .
There is exactly one location for each wheel.
The jack must not be positioned at any other locat ion
c:> ,&. c:>(D .
Soft ground under the jack can cause the ve­
h icle to slip off the jack. Always place the jack
on firm ground. Use a flat, stable support if necessary . Use a non-slip surface such as a
rubber mat on a
slipp ery surfac e such as tile .
A WARNING
-You or your passengers could be injured
wh ile chang ing a wheel if you do not fol­
low these safety precautions :
- Position the vehicle jack only at the
des ignated lifting points and align the
jack. Otherwise, the vehicle jack could slip and cause an inj ury if it does not
have sufficient hold on t he veh icle .
- A soft or u nstab le surface under the
jack may cause the veh icle to slip off
the jack . A lways provide a firm base for
the jack on the ground.
If necessary,
use a sturdy boa rd un der the jac k.
- On hard, slippery surfac e (such as til es)
use a rubbe r mat o r similar to preven t
the jack from s lipping.
- T o help p revent injury to yourself and
yo ur p assenge rs: -
Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve­
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the veh icle and
well away from the road and traffic .
- Make sure jack pos ition is cor rect, ad­
j ust as necessary and then cont inue to
raise the jack.
(D Note
Do not lift the vehicle by the sill. Position
the veh icle jack only at the designated lift­
i ng po ints on the sill. Otherwise, your vehi­
cle will be damaged.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction.
Us ing a spa re tire with a tread pattern
intended for use in a specific di rection
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection, please
note the following :
- The d irect ion of rotation is marked by an
ar­
row on the side of the t ire .
-If the spare tire has to be insta lled in the in­
correct d irect ion, use the spare tire only
temporarily s ince the tire will not be able to
achieve its optimum performance cha racte r­
istics w it h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu lar at ­
t en tion to th is fact during we t weather and
that you adjust your speed to match road
condi tions.
- Replace the flat t ire wi th a new one a nd
