ABS AUDI S4 2017 Owner's Manual

and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating and being pushed out of the cooling system.
A WARNING
- The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns .
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. There may be a ir in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance .

Before you check anything in the eng ine compart ­
ment,
always read and heed all WARNINGS
Checking and Filling
c::> .&. in Working in the engine compartment on
page 304.
" Read the brake fluid level from the brake fluid
reservoir
c::> fig. 250, c::> page 306, fig. 247. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The brake flu id reservoir is located at the rear
partition of the engine compartment on the left
side
~ page 306 .
The fluid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm.
If the brake fluid level falls considerably below
the "MIN" mark, the brake warning/indicato r
light (USA models:
11111 , Canada models : II>
will come on c::> page 29. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/indicator light will illuminate .
Contact an authorized Audi dealer
immediately .
@ Tips
The brake fluid reservoir is located under­
neath the cover.
Changing brake fluid
Hove the broke fluid changed by on experienced
technician.
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape­
riod of time. The boiling point of the brake fluid
will also decrease considerably and decrease braking performance .
Therefore, the brake fluid must be changed
every
two years .
Always use new brake fluid which con­
forms to Federal Motor Vehicle Standard "FMVSS
116 DOT 4" .
The brake fluid reservoir can be difficult to reach,
therefore, we recommend that you have the brake fluid changed by your authorized
Audi
dealer.
Your dealer has the correct tools, the

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 ­
fi cation) 17 0 3 and confo rms to Fede ral
Motor Ve hicle Standard 116. Always check
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
ommend tha t you have the brake fluid
changed by your author ized Audi d ealer.
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

&_ WARNING . -
-Only use tire/rim combina-tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than six years old when abso­
lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
Wheels
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 254 Tire profile: treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear more quickly. .,..

significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-infla­
tion also reduces fue l eff ic iency and tire tread
life, and may affect the vehicle's hand ling and
stopping ab ility.
Please note that the TPMS is not a substitute for
proper tire ma intenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the leve l
to tr igger illum inat io n of the TPMS low tire p res­
sure telltale .
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly. The TPMS mal­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approxi­
mate ly one m inute and then remain cont inuo usly
illum inated. This sequence will continue upon
subseq uent ve hicle start -ups as long as the ma l­
function exists.
When t he mal funct io n ind icator is ill umin ated,
the system may not be ab le to detec t or signal
l ow tire pressure as intended. TPMS ma lfunctions
may occur for a variety of reasons, incl uding the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your ve hicle to ensu re
that the replacement or alte rnate ti res and
wheels a llow the TPMS to con tinue to func tion
p roperly.
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system mo/function.
Using the ABS sensors, the tire pressure mo nitor ­
