-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions inc:::> page 203,
Tires and vehicle load limits.
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in ­
creases tire wear and has a
negative effect on driving and

braking behavior, which in ­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a
normal load c:::>
table on
page 203
or for a full load
when the vehicle is partially
loaded.
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.
The following table lists recom­ mended tire pressures in cold
tires according to the load and
the size of the tires installed.

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuous ly
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be ab le to detect or signal
low tire pressure as intended . TPM S malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly . Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

If the Tire Pressure Monitoring System
indicator appears
Applies to vehicles : wi th tire pressure mo nito rin g sys te m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 160 Instrument cluster : indicator lig ht with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumfer­
ence and vibration characterist ics of the ind ividu ­
al tires. If the pressure changes in one or more
t ire s, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
ti re will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ~
page 210. The tire pressure moni­
toring system on ly monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
¢ page 201, fig . 159.
Tire tread c ircumference and vibration character­
istics can change and cause a tire pressure warn­
ing if :
- the tire pressure in one or more tires is too low.
- the tir e has str uctural damage.
- the tir e was replaced or the tire pressure was
changed and it was not stored¢

So ft gr ound under the jack can cause the ve hicle
to slip off the jack . Always p lace the jack on firm
ground. Use a flat, stab le support if necessary .
Use a non-slip surface such as a rubber mat on a
s lipp ery s urface such as tile.
A WARNING -
-You or your passengers could be injured
while changing a wheel if you do not follow
these safety precautions:
- Position the vehicle jack only at the des ig­
nated lifting points and align the jack .
Otherwise, the vehicle jack could slip and
cause an injury if it does not have suffi ­
cient hold on the vehicle.
- Use only the jack* supplied w ith your veh i­
cle to raise the vehicle . If you use a jack
from a different vehicle, your vehicle may
slip off the jack - risk of injury!
- Do not use the jack* supplied with your ve­
hicle to raise other vehicles, as these may
slip off the jack - risk of injury!
- A soft or unstab le surface under the jack
may cause the vehicle to slip off the jack.
Always provide a firm base for the jack on
the gro und .
If necessary, use a sturdy
board unde r the jack.
- On hard, slippery surface (such as t iles)
use a rubber mat or similar to prevent the
jac k from slipp ing .
- To help prevent injury to yourself and your
passengers:
- Do not raise the vehicle until you are sure
the jack is securely engaged.
- Passengers must not rema in in the vehicle
when it is jacked up.
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic . .,_

Emergency assistance
- The wheel bolts should be clean and easy to
turn. Check for di rt and cor ros ion on the
mating s urfaces o f both the whee l an d the
h ub. Remove all dirt from t hese surfaces be­
fo re remo unt ing t he wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car m ust first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend t hat you have
your authorized Aud i dea le r rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n light s):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
fied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
