wheel AUDI S4 2008 User Guide

Driver information system
40The tyre pressure monitoring system makes use of the ABS sensors
to compare the rolling circumfe rence and the vibration of the
wheels. The display in the instrument cluster alerts the driver if
changes are detected on one or more wheels. If only one tyre is
affected, the display will indicate its position ⇒fig. 27.
Each time you change a tyre or the tyre pressures on your vehicle,
you must store the new tyre pressures via the sound system or
MMI* ⇒page 41 .
The rolling circumference and vibration can change if:•
The tyre pressure is too low
•
The tyre has suffered structural damage
•
The air pressure in one or more tyres was changed and the new
tyre pressures were not stored ⇒page 41, “Storing the tyre pres-
sures”
•
The wheels were changed and the new tyre pressures were not
stored ⇒page 41, “Storing the tyre pressures”
•
There is a greater load on the wheels of one axle (e.g. if you are
carrying more passengers or luggage)
•
The road surface under the left wheels is different to the road
surface under the right wheels for a long period
Warning lamp
 / TPMS Tyre pressure ! System malfunction
If the warning lamp  flashes for about a minute and then remains
lit after you switch on the ignition, there is a fault in the system. TPMS
(Tyre Pressure Monitoring System) Tyre pressure ! System
malfunction ⇒ page 40, fig. 28 will also be displayed in the instru-
ment cluster. Please contact the ne arest qualified workshop as soon
as possible.
WARNING
•
If the tyre pressure warning lamp appears in the instrument
cluster display, slow down i mmediately and avoid any severe
braking or steering manoeuvres. As soon as you can do so safely,
stop and check the tyres and the tyre pressures.
•
It is the driver's responsibility to ensure that the tyre pressures
are correct. For this reason yo u must check the tyre pressures
regularly.
•
Under certain conditi ons (e.g. driving at high speeds, on ice and
snow or on poor road surfaces) the tyre pressure warning lamp
may not light up immediately or not at all.
•
Please ask your Audi dealer or qualified workshop whether run
flat tyres can be used on your vehicle. Unauthorised use of these
tyres can invalidate the vehicle's type approval for use on public
roads. Furthermore, this could cause damage to your vehicle and
possibly also result in an accident.

– Turn the button clockwise +” to increase the brightness of the instrument lighting in dark conditions.
– Turn the button anti-clockwise -” to reduce the bright- ness of the instrument lighting in dark conditions.
– Press the knob in again to prevent the setting from being changed unintentionally.The instrument lighting (dials and needles), the centre console illu-
mination and the illumination of the displays are regulated by a
light sensor incorporated in the instrument cluster. In bright condi-
tions any changes made to the brig htness of the instrument lighting
have no effect.
Note
The instrument lighting (illumination of dials and needles) is
switched on when the ignition is on and the vehicle's lights are off.
The instrument lighting is dimme d automatically as the daylight
starts to fade; it is switched off completely when the light condi-
tions become very poor. This function is intended to remind the
driver to switch on the dipped-beam headlights in good time when
light conditions become poor.
Applies to vehicles: with headlight range controlHeadlight range control

When the dipped beam headlights are switched on, the
range of the headlights can be adjusted to suit the load
being carried.– Turn the thumbwheel
 ⇒ fig. 58 to the appropriate
setting.
Adjustment settings
The settings correspond roughly to the following load conditions:
Two front occupants, luggage compartment empty
All seats occupied, luggage compartment empty
All seats occupied, luggage compartment loadedDriver only, luggage compartment loaded
Caution
Always adjust the headlights to avoid dazzling oncoming traffic.
Make sure you lower the headlights when the vehicle is carrying a
heavy load.

Technical data
Applies to vehicles: with xenon headlight bulbsDynamic headlight range controlHeadlights with xenon gas-discharge bulbs automatically adapt to
suit the load being carried when the engine is switched on. The
headlights are also automatically adjusted when the vehicle is in
motion (e.g. when accelerating and braking).Applies to vehicles: with adaptive lightadaptive light
This feature provides better illumination when you drive
through a corner.The adaptive light gives better illumination of the bend and the side
of the road when driving through a corner ⇒fig. 59. The adaptive
light is controlled automatically, depending on the speed of the
vehicle and the steering wheel angle.
The headlights are regulated automatically when you drive through
a corner, depending on how far you turn the steering wheel. To
avoid having a dark spot in front of the vehicle the two headlights
are directed at different angles.
Note
The system is active at speeds from approximately 10 km/h to
110 km/h.Hazard warning lights

The hazard warning lights ar e used to make other road
users aware of your vehicle in hazardous situations.– Press the switch
 to switch the hazard warning lights
on or off ⇒fig. 60.
All four turn signals flash simultaneously when the hazard warning
lights are switched on. The two turn signal indicator lamps
  and
the indicator lamp in the switch
 will flash at the same time. The
hazard warning lights also work when the ignition is switched off.
The hazard warning lights come on automatically in the event of an
accident in which an airbag is triggered or in the case of an emer-
gency stop (full br ake application).
Note
You should switch on the hazard warning lights to warn other road
users, for instance:

heating is switched on, this setting will remain activated for 15
minutes after switching off the ignition.
If the engine is started again during this period of 15 minutes, the
rear window heating will be switched on for about 10 to 20 minutes,
depending on the exterior temperature. This means you do not have
to manually switch on the rear window heating again if the vehicle
has only been parked for a short time.
For the sake of the environment
Switch off the heated rear window manually as soon as the rear
window is clear. By saving electrical power you can also save fuel.Applies to vehicles: with deluxe automatic air conditioner plusAC mode Deactivating the AC mode

Applies to vehicles: with deluxe automatic air conditioner plusEconomical operation of the air conditioner
Economical operation of the air conditioner will help to
save fuel.When the air conditioner is operating in the cooling mode it
reduces engine power and incr eases fuel consumption. To
ensure that the cooling mode is activated only when really
necessary, please note the following points:
– Switch off the cooling mode by pressing the AC button (LED off) if you wish to save fuel.
– You should also switch off the cooling mode by pressing the AC button (LED off) if you open the windows or the
tilting panorama roof* while driving.
– If the vehicle has heated up after standing in the sun, open the windows and doors for a short time to cool the
vehicle.
For the sake of the environmentBy saving fuel you also reduce the amount of pollutants emitted
from your vehicle.
