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, rad io, etc., as we ll
as the battery charger.
Battery replacement
The new battery must have the same specif/·
cations and dimensions as the original equip­
ment battery.
In tell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughout you r vehicle
~ page 186. The intell igen t energy m anage­
men t system w ill keep the engine ba tte ry
charged better then vehicles w ithout this sys­
tem . To make sure the additional e lectrica l en­
ergy is available once again after you have
changed the battery, we recommend that you install batteries o f the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. You r
author ized Audi dealer must code the battery
in the ene rgy managemen t system to enable
you to use the ene rgy management functions
correctly after replac ing the battery.
I f it is not poss ible to use a battery of this
type, the new bat tery m ust h ave the s ame ca­
pac ity, voltage ( 12-volts), amperage, con ­
struction and plug sea ling. When installing the battery, make su
re the ig ­
nition and a ll electrical consumers are turned
off.
(D Note
Make sure the ventilat ion hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out .
@ For the sake of the environment
Because o f the p rob lem of p roper disposal
of a battery, we recommend your author ­
i zed Audi dealer change the battery fo r
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop­
erly in comp liance with all environmental
regula tions. Dispos ing of veh icle batter ies
i mprope rly is very dange rous to the envi­
r o nment .

24 4 What do I do no w?
There are some restrictions on the use of the
compact spare tire. The compact spare tire
has been des igned specifically for your type of
vehicle.
It must not be swapped with a com­
pact spare tire from another type of vehicle.
Sno w cha in s
For technical reasons, the use of snow chains
on the compact spare tire is
n ot permitted .
If you do have to dr ive with snow cha ins and a
front tire fails, mount the spare wheel w ith
tire instead of a rear tire. Install the snow
chains on the rear tire and use it to rep lace
the defective front tire.
A WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex­
t reme caution and careful driving.
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and t ire.
- After mounting the compact spare tire, the tire pressu re must be checked as
soon as poss ible. The tire pressure of the
c ompac t spare tire must be 4.2 bar; oth­
erwise, you risk hav ing an accident.
- Do not drive faster than 50 mph (80 km/
h). You r isk having an acc ident.
- Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . Yo u risk hav­
ing an acc iden t.
- Never dr ive us ing more than one spare
wheel and tire. You risk having an acci­
dent.
- No rma l summer o r winte r ti res m ust not
be mounted on the compact spare whee l
rim.
- F or te chnical reasons, the use o f ti re
chains on the spare tire is not permi tted .
If it is necessary to drive with tire chains,
the spare whee l must be mounted o n the
front axle in the event of a f lat in a rear tire. The new
ly available front wheel
must then be installed in place of the
rear whee l with the flat tire. Installing
the t ire cha in before mounting the whee l
and tire is recommended .
- Loose items in the passenger compart­
ment can cause serious personal injury
during hard brak ing or in an accident.
Never store the spa re tire or jack and
too ls in the passenger compa rtment.

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to carry the starter current
safely. Refer to the manufacturer's specifica­
tions.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 255
-A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes 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
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery. Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 206.
(D Note
- Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc.
- There must be no electrical contact be­ tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,. •
•

-Jumper cables must be long enough so
that the vehicles do not t ouch.
- W hen connecting jumper ca bles, make
sure that they cannot get caught in any
moving parts in the eng ine compart­
ment.
- Do not bend over the batteries - danger
of chemical burns!
- The battery ce ll locking screws must be
t ightened securely .
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
page 206.
Improper hook-up of jumper cables can ru­
in the generator.
- Always connect POSITIVE( +) to POSI ­
TIVE(+), and NEGATIVE( -) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that all screw plugs on the battery
ce lls are screwed in firmly . If not, tighten
plugs p rior to connecting clamp on nega­
tive battery terminal.
- Please note that the procedure for con­
necting a jumper cable as described
above applies spec ifically to the case of
your vehicle be ing jump started. When
you are givi ng a jump start to another ve­
hicle, do
not connect the negat ive( -) ca­
ble to the negat ive( -) term inal on the
discharged battery @¢
fig. 188. In­
stead, securely connect the negative(- )
cable to e ither a solid metal component
that is firmly bolted to the engine block
or to the engine block itse lf. If the bat­
tery that is being charged does not vent
to the outside, escaping battery gas
could ignite and explode!

of your vehicle and even void your vehicle war­ ranty. The refo re, p roof of servic ing in accord­
ance w ith the maintenance sched ule may be a
condition for upholding a poss ible war ranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, crea ting unnecessary risks for you
and your passengers.
If in doubt about any servicing, have it done
by your authorized Audi dealer or any properly
