e rgy is available once again after you have
changed the battery, we recommend that you install batteries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery hous ing . Your
author ized dealer must code the battery in
the energy manageme nt system to enable yo u
to use the energy managemen t fu nctions co r­
rectly after rep lac ing the b attery .
If it is not poss ible to use a battery of this
type, the new battery must have the same ca­
paci ty, voltage ( 12 volts) , a mpe rage , con ­

The correct tire pressure for the spare wheel i s
l ocated on a label on the driver's side 8-pilla r.
Because technical changes may be made to
vehicle equ ipment dur ing the model year , al­
ways compare the tire size designation on the
tire pressure label on your vehicle w ith the
tires on you r vehicle. Ma ke su re that the tire
si ze information on the ve hicle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be­ l ongs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
ve hicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on making sure that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are technically refer­ red to as the vehicle's Gross Vehicle We ight
Rating ("GVWR") . The Gross Axle Weight Rat­
i ng ( "GAWR") is the maximum load that can
be appl ied at each of the veh icle's two axles.
The G ross Vehicle Weight Rating and the Gross Axle Weig
ht Rating are listed on the
safety comp liance sticker label located on the
drive r's side 8-pillar . The tire pressure labe l on
yo ur A udi lists t he maxim um combined
weight of all o f the occ upants and luggage or

A WARNING
Overloading a vehicle can cause loss of ve­
h icle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been overloaded may not be able to stop the
veh icle w ith in a safe distance.
- T ires on a vehicle that has been overload ­
ed can fail suddenly ca using loss of con-
trol and a crash . ..,.

bled correctly.
A WARNING
Improper use of the vehicle jack can cause
ser ious persona l injuries.
- Never use the jack supplied with your Au­
di on anothe r vehicle, pa rticularly on a
heavier one. The jack is only suitable for
use on the vehicle it came w ith.
- Us ing a bumper jack to raise the vehicle
will damage the bump er system. The
jack may slip, causing in jury.
- Never support your veh icle on cinder
blocks, b ricks or other objec ts. These
may no t be ab le to suppor t the load and
c ou ld cau se injury whe n they fail.
- Never start o r run the engine while the
vehicle is supported by the j ack.
- If you must wo rk under the vehicle, al­
ways use safety stands specifically de­
signed for this purpose.
- Always make su re the inf latable spare

Bulbs
Replacing light bulbs
For your safe ty, we recommend that you hove
your authorized Audi dealer replace burned
out bulbs for you.
It i s becom ing increasing ly more and mo re
diffic ult to replace vehicle ligh t bu lbs since in
many cases, other parts of the car must fir st
be removed befo re you are able to get to the
bulb. This applies especially to the light bulbs
in the front of your car which you can only
r each th rough the engine compartment .
Sheet meta l and bu lb holders can have sharp
edges that can cause serious cuts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break ­
age of pa rts and long term damage from wa­
te r that can enter housings that have not been
properly re sea led. ..,.

For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you, s ince your dealer has the proper tools,
the correct bu lbs and the expertise.
G as discharg e lamps (Xenon li ght s)*:
Due to the high elect rical voltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon light can be identified
by the high voltage sticker .
~ WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause serious personal in­
jury and death .
- Xenon bulbs are pressurized and can ex­
plode when be ing changed.
- Chang ing Xenon lamps requires the spe­
c ial train ing, instructions and equip­
ment.
- Only an authorized Aud i dea ler or other
qualified workshop should change the
bulbs in gas discharge lamps.
A WARNING
There are parts with sharp edges on the
openings and on the bulb holde rs that can
cause se rious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dea le r or other qua lified work­
shop. Serious persona l injury m ay result
from improperly performed work .
@ Tips
-If you must rep lace the light bu lbs your­
se lf, always remembe r that the engine
compartmen t of any vehicle is a hazard­
ous area to work in . Always read and
heed all WARNINGS

308 Emergency situations
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
Q;) Note
Your vehicle is equipped with an automatic
transmission. Consequently, the engine
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 large
cross section to carry the starter current safe­
ly. Refer to the manufacturer's specifications.
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. -
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 capacity (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 248, Engine com­
partment.
@ 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. ..,.

@ Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump start ing or charging the
battery, never connect the negative
ground cable to the battery negative
post because the battery manager sys­
tem must be able to detect the battery's
state of cha rge. A lways connect the neg­
ative g round cab le to the negative
gro und post o f the battery manage r con­
trol uni t.
Use of jumper cables
