2008 AUDI S8 instrument cluster

The j warning light in the instrument cluster comes on when the
tire is significantly underinflated.
In addition, the tire symbo l
) appears in the display together with
the message
Please check tire pressure => page 42, fig. 25.
Af ter a few seconds, the message disappears again:::>

!CHECK] button.
[ i] Tips
• In the case of an intentional loss of air pressure, for example,
when re-adjusting tire pressure, this has to be stored again after­
wards =>
page 44.
• Current information about tire pressures and temperatures can
be scanned in MMI =>
page 43.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient a ir temperature .
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system=>
page 44.
• After changing a wheel you have to adjust the tire pressures on
all whee ls . In addition, you must then initialize the new tire pres­
sures in the tire pressure monitoring system =>
page 45.
• If your vehicle is equipped with a spare tire* with a wheel sensor,
the tire will be monitored and the display
symbols => page 42, fig. 25
or=>
page 42, fig. 26 will appear if the pressure is too low.•

If the ...., warning light in the instrument cluster flashes for approxi­
mately one minute and then remain continuously illuminated and
additional ly the
=> fig. 29 symbol appears in the display, the
tire pressure monitoring system is not available. This can have
various causes.
• If the message appears at the end of the learning process, the
system cannot recognize the wheels installed on the vehicle. This
can be because one or more wheels without a wheel sensor were
insta lled .
• A wheel sensor or other component may have failed.
• The system has detected more than 5 wheels with wheel sensors
in the vehicle, for example when carrying snow tires.
• A tire was changed but the
Initialize wheels function was not
activated
=> page 45.
• Audi replacement parts were not used.
• If snow chains are being used, system function can be compro­
mised due to the shielding properties of the chains.
• The tire pressure monitoring system may not be available
because of a radio malfunction.

Electronic immobilizer
The immobilizer helps to prevent unauth orized use of

vehic les with Advanced Key*, when the key is inside the vehicle .
When you remove the key from the ignition lock, or on vehicles with
Advanced Key, when you remove the key from the vehicle, the elec­
t ronic immobilizer is automatically activated once again.
If an unauthorized key was used,
S AFE is disp layed continuous ly in

Your vehicle is equ ipped w ith an electromechanical parking brake
which replaces the handbrake . The parking brake is designed to
prevent the vehicle from rolling unintentionally .
In addition to the norma l functions of a trad itiona l hand brake, the
e lectromechanical parking brake provides various convenience and
safety functions.
Em erg ency brake
An emergency brake ensures that the vehicle can be slowed even if
the
normal brakes fa il=> page 136, "Emergency braking".
Indi cat or light s
• If the pa rking brake is app lied with the ignition turned on , the
indicator light in the instrument cluster (U.S. models:
::i , Canadian
models: ©) and in the switch © will come on .
• If the parking brake is applied with the ignition
tu rn ed off , the
indicator light in the instrument cluster (U .S .
models :~~ . Canadian
models :(®) ) and in the
switch (®) will come on for about 30 seconds
and then go out.
& WARNING
I f the vehicle i s stati onary and the transmis sion i s engaged with
the eng ine runnin g, the engine should n ot b e speeded up (e .g .
manu ally from under the ho od). Otherw ise th e vehi cle w ill start to

0 Note
If the warning/indicator light (U .S . models: BRAKE , Canadian models:
«D>) flashes in the instrument cluster, there is a brake system
malfunction . By pressing the
I CH ECK] button , you can bring up a
driver message which explains the malfunction in more detail. If the
message
Parking brake! Plea se conta ct w ork shop appears, there is
a parking brake malfunction which you should have repaired imme ­
diate ly by an authorized dealership =>
page 30.
[ i] Tips
• You can app ly the parking brake at any time -even with the igni ­
tion turned off . T he ignition must be turned on in order to release
the parking brake.
• Occasional noises when the parking brake is applied and
released are norma l and are not a cause for concern .
• The parking brake goes through a se lf -test cycle at regular inter ­
va ls
-when the vehicle is parked. Any associated no ises are
normal. •

___ o_ n_ t_
h _e _ ro_ a_d __________________________________________________ _
Starting off with a trailer To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and prevents the vehicle
from rolling backward.
- You can release the switch once you are sure that you are
developing enough forward momentum at the wheels as
you depress the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch
pulled out and accelerating -just as you would when starting on a
hill with a conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- Pull the switch and continue to pull it to slow your vehicle
with the parking brake in an emergency.
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated . The vehicle is
braked at all four wheels by activating the hydraulic brake system.
Brake performance is similar to making an emergency
stop~ &.
So that emergency braking is not activated by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled . As soon as the switch is released
, or the accelerator pedal is depressed, emer­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle as if you had made a full brake application. The laws
of physics cannot be suspended even with ESP and its associated
components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away -risking an
accident. •
Driver messages in the instrument cluster
Caution: Vehicle parked too steep
This message appears when the parking brake is applied on an
incline that exceeds about 30%.
In this case the braking power of the parking brake may
not be
adequate
to prevent the vehicle from rolling unintentionally.
Please release parking brake
This message appears, when a gear is selected and the accel erator
pedal is depressed -release the parking brake.
Press brake pedal to release parking brake
This driver message appears when the switch to release the parking
brake was pressed. The parking brake can only be released if you
press the brake or accelerator pedal and press the switch at the
same time .
~ Parking brake malfunction !
This driver message appears together with the yellow 'Jlf symbol
when there is a parking brake malfunction.
