water pump AUDI S3 2012 Owners Manual

As soon as the test is completed, the system
is in normal operating mode.
Switching off
E SP should normally be activated at all times
because this ensures optimum vehicle stabil i­
ty. In certa in situations, it might make sense
to a llow some slip . For example:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow cha ins
Press the
[!I button . The ESP indicator light I)
turns on and S tabil isat ion prog ram off ap­
pears in the d isp lay. ASR deact ivates com­
pletely and the stab ilizat ion effects from the
ESP system are lim ited.
S wi tc hing on
Press the [!I button again. The message S tab i·
li sa tion p rogram on
appears briefly in the dis­
play.
A WARNING
You should only sw itch the ESP off if your
driving ability and the traffic s ituation per­
m it. Please note that when ESP/ASR is de­
act ivated, the drive whee ls can sp in on icy
and slippe ry roads and the vehi cle can
break away - danger of skidding!
(j) Tips
If A udi magnetic ride* is malfunctioning,
the ESP may not switch off or it may
sw itch off automatically.
Braking
General information
What affects braking efficiency?
Operating condit ions and d riving habit s
The brakes on today's automobi les are st ill
subject to wear, depending largely on operat­
ing cond itions and dr iving habits
q .&. . On ve ­
hicles that are either driven mostly in stop­
and -go city traffic or are driven hard, the
brake pads should be checked by your author-
Int ellig ent technolog y 163
ized Audi dea ler more often than specified in
the
W arra nty & M aintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you sho uld use the b raking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont inuously. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
speed, braking force and outs ide cond it ions
such as temperature and humidity.
Mo isture o r road sal t
If you are driving faster than SO mph (80 km/
h) and the windshield wipers are on, the brake
pads will briefly touch the brake discs in regu­
lar intervals so as to improve react ion time
when brak ing on wet surfaces. You, the driver,
will not not ice anything.
Under certain conditions, for example, when
driv ing through water or very heavy ra in, or
even after washing your veh icle, the braking
effect can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads. A
few cautious brake applications should dry off
the b ra ke pads or remove any ice coatings.
The effectiveness of the brakes ca n be reduced
when the vehicle is driven on a salt-cove red
road and the brakes are not used. l ikewise,
you clean off accumulated salt coating from brake d iscs and pads w ith a few cautio us ap­
plications o f the b ra ke
¢ .&, .
Corrosion
T here may be a tendency for di rt to b uild up
o n the brake pads and corros ion to fo rm on
the d iscs if the car is not d riven regu larly or
o nly for short tr ips w ith litt le use of the
brakes.
If the brakes a re not used frequently, o r if cor­
ros ion has formed on the discs, it is adv isable
to clean off t he pads and d iscs by braking
firmly a few times from a moderately high
speed ~.&. . .,.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb. This applies especially to the light bulbs
in the front of your ca r which you can only
reach through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, and parts
must be cor rectly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa ­
ter that can enter housings that have not been
properly re sea led.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified techn ic ian.
Head lights with Xenon light can be identified
by the high voltage sticker.
_& WARNING ~
Contact with high-vo ltage 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 pressur ized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial tra ining, instructions and equip­
ment.
- On ly an authorized Audi dealer or other
qualified workshop should change the bulbs in gas discharge lamps .
