2017 AUDI S4 headlights

A WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.
@ Tips
-Depending on vehicle equipment, the in­
strument illumination (needles and gauges) may turn on when the lights are off and the
ignition is switched on. The illumination for
the gauges reduces automatically and even­
tually turns off as brightness outside in­
creases. This function reminds the driver to
turn the low beams on at the appropriate
time.
- You can select the units used for tempera­
ture, speed and other measurements in the
Infotainment system c::>
page 229.
-If your vehicle is stationary or if you are driv­
ing at very low speeds, the temperature dis­
played may be slightly higher than the ac­
tual temperature outside due to the heat ra­
diating from the engine.
- At temperatures below 41 °F (+5 °C), a
snowflake symbol appears in front of the
temperature display c::>
A.
Coolant temperature indicator
The coolant temperature display@c::> page 10,
fig . 3
or c::> page 10, fig. 4 only functions when
the ignition is switched on. To prevent engine
damage, please observe the following notes
about the temperature ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet . Avoid high engine speeds, full ac­
celeration and heavy engine loads.
Normal range
<( ~ The engine has reached its operating tempera-
~ ture once the LEDs up to the center of the gauge N
8 turn on under normal driving conditions. The 0
3 Cockpit overview
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
This is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on. If the LEDs in the upper area of the dis­
play and the. indicator light in the instrument
cluster display turn on, the coolant temperature
is too high
c::> page 31.
(D Note
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en­
gine load.
- The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa­
cility for assistance.
(D Tips
Diesel engines: due to the high efficiency of
these engines, the engine may not always reach operating temperature in cold outside
temperatures. This is normal and not a cause
for concern .
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
The beginning of the red zone in the tachometer
indicates the maximum permitted engine speed
for all gears once the engine has been broken in
and when it is warm . Before reaching this zone,
you should shift into the next highest gear, select
the D/S selector lever position, or remove your
foot from the accelerator pedal.
{Q) Note
The needle in the tachometer @c::> page 10,
fig. 3
or c::> page 10, fig. 4 may only be in the
red area of the gauge for a short time or there ..,.

A WARNING
- T he rain sensor is only intended to assist the
driver. The driver may still be responsible
for manually switching the w ipers on based
on v is ibility conditions.
- The w indshie ld may not be treated with wa­
ter -repelling windshield coating agents. Un­
favorable conditions, s uch as wetness, dark­
ness or low sun, can result in increased
glare, which increases the risk of an acc i­
dent . Wiper blade chatter is also poss ible.
- Properly functioning windsh ield wiper
blades are required for a clear view and safe
dr iv ing to red uce the risk of an accident
Light s and Vision
c::> page 58, Changing windshield wiper
blades.
@ Note
- If there is frost, make sure the windshield
wiper blades are not frozen to the wind­
shield. Switching on the windshield wipers
when the blades are frozen to the wind­
shield can damage the w iper blades.
- Prior to using a car wash, the windshield
wiper system must be sw itched off (lever in
position
0). This prevents the wipers from
switching on unintentionally and caus ing
damage to the windsh ield wiper system.
@ Tips
- The windshield wipers switch off when the
ign ition is switched off. You can activate the
w indshield wipers after the ignition is
switched back on by moving the w indshield
w iper lever to any position.
- Wor n or dirty w indshie ld w iper blades resu lt
in st reaking. T his can affect the rain senso r
function. Check your windshield wiper
blades reg ularly.
- The washer fluid nozz les for the windshield
washer system are heated a t low tempera­
tures when the ignition is on .
- Whe n stopping tempo rar ily, such as at a
t raffic lig ht, the speed of the windshield
wipers automatically reduces by one level.
Cleaning windshield wiper blades
Clean the wiper b lades when you see wiper
streaks. Use a soft cloth and a g lass cleaner.

right brake fluid and the know -how to do this for
you.
A WARNING
- Brake fluid is poisonous. It must be stored
only in the closed orig inal container out of
the reach of chi ldren!
- B rake failure can resu lt from old or inappro­
pr iate brake flu id. Observe these precau­
t ions:
- Use on ly brake fluid that mee ts SA E speci ­

wit h your authorized Audi dealer to make
sure you are using the correct brake fluid.
The cor rect type o f brake fluid is a lso indi­
cated on the brake fluid reservoir.
- The brake fluid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake flu id is left in the system too long.
This ca n ser iously affect t he efficiency of
the bra kes as well as your safety. This
could result in an acc ident.

@ For the sake of the environment
Because of the prob lem of proper disposal of
brake flu id as we ll as the special tools re­
quired and the necessary expertise, we rec­

Battery
General information
Unde r normal operating conditions, the battery
i n your Audi does not need any maintenance.
W ith
high outs ide temperat ures o r long da ily
d rives we recommend that you have the electro­
lyte leve l checked by an a uth orized Audi dea le r or
qua lified wor kshop. The e lectroly te leve l should
a lso be checked each time the batte ry is ch a rged
¢ page 314.

Have t he battery chec ke d when yo u take yo ur ve ­
hicle in for service . You are we ll advised to re­
place a battery that is o lder than 5 yea rs .
With ce rta in types o f airbag deployment, t he
b atte ry is disconnected from the veh icle elect ri­
ca l system for safety reasons ¢.&
in Repair, care
and disposal of the airbags on page 268.
Disconnecting the battery terminals
Some ve hicl e fu nctions (power window regula ­
tors, for examp le) are lost if the batte ry te rm i­
nals a re disconnected . These f unc tions have to be
relearned after the battery term inals are con­
nected again . To p revent this, the battery should
o nl y be disconnected from the vehicle electrical
system when absolute ly necessary for repairs.
Vehicles not driven for long periods
If you do not d rive yo ur vehicle ove r a period of
severa l days o r weeks, electr ica l components are
grad ua lly cut back or switched of f. T his reduces
energy consumpt ion and maintains start ing ca­
pability over a longer period ¢
page 138.
Some of the convenience functions may not oper­
ate, such as the inter ior lights or the power seat
adjustment . The convenience functions will be
available again w hen you turn on the ignit io n and
start the eng ine .
Winter operation
Dur ing the winte r months, battery capacity tends
to decrease as tempe ratures drop. This is be ­
ca use more power is also consumed while start­
i ng, and t he headlights, rear w indow defogger,
etc ., are used more often.
Avo id unnecessary powe r consumption, partic u­
l a rly in city traffic or when traveling o nly short
distances . Let your author ized Audi dealer check
the capacity of the vehicle battery before win ter
sets in ¢
page 314 . A well charged battery will
n ot only p reve nt sta rting prob lems when the
we ather is co ld , but will also last longer.
