brakes AUDI A4 2016 Owner's Manual

Check ing and F illing
The brake fluid rese rvoir is located at the rear
partition of the engine compartment on the l eft
side ¢
page 205 .
The fl uid level may drop slightly after some time
due to the automatic adjustment of the brake
pads . This is not cause for alarm.
If th e b rake fl uid level fa lls considerably be low
the "M IN" mark, the b rake warning/ind icator
lig ht ( U.S. mode ls :
1111 , Canadian models:. )
will come on ¢
page 15. Do not contin ue to oper ­
ate the vehicle . T he comp lete brake system
should be thoroughly checked by an authori zed
Aud i dealer or qualified workshop and the cause
corrected . If the brake flu id level is too low, the
b rake warning/indicator light will i llum inate.
Contact a n author ized Audi dealer
immediately .
{D) Tips
The brake fluid reservoir is located under­
neath the cover .
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs mo isture from the air. If the
water content in the b rake fluid is too high, cor­
rosion in the brake system may resu lt afte r ape ­
riod of t ime. The boiling poi nt of the brake flu id
will also decrease cons iderably and decrease
b raking perfo rman ce.
Therefore, the brake fluid must be changed
every
two year s.
Always use new brake fluid wh ic h con­
forms to Fede ral Motor Veh icle Standard "FMVSS
1 16 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that yo u have the
brake fl uid changed by yo ur autho rized
Audi
dealer .
Your dealer has t he corre ct tools, t he
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!
212
- Bra ke fa ilure ca n result from old or inapp ro­
priate brake fluid . Observe these precau­
tions:
- Use only brake fluid t hat meets SA E speci­
fi ca ti on
J 170 3 and con forms to Federa l
Motor Ve hicle Standard 116 . Always check
wi th yo ur autho rized Audi dea le r to make
s ur e yo u are using the correct brake fluid .
The correct type of brake flu id is also ind i­
cated on the b rake fluid reservo ir .
- The brake fluid m ust be new . Heavy use of
the brakes can cause a vapo r lock if the
brake fluid is left in the system too long .
This can se riously affect the efficiency of
the b rakes as well as your safety . This
could resu lt in an accident .
(D Note
Brake fluid will damage the paint of your veh i­
cle.
@ For the sake of the environment
Because of the problem o f proper d isposa l o f
brake fluid as well as the spec ial too ls re­
q ui red a nd the necessary expertise, we rec­
omme nd that you have the bra ke f luid
changed by yo ur autho rized Aud i dea le r.
Battery
, General information
U nder normal operating condit ions, the battery
i n your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the elect ro ­
lyte level c hecked by an au thorized Aud i dealer o r
qualified workshop. The electro lyte level shou ld
a lso be che cked each time the battery is c ha rged
~ page 214.
Have the batte ry chec ked when you take yo ur ve­
hicle in for service. You are we ll adv ised to re­
pla ce a battery tha t is older than 5 yea rs.
With certain types of airbag deployment, t he
batte ry is d iscon nected from the ve hicle electri­
ca l system for safety reasons ¢.&.

"M/5 " or "M+S" indicates the tire
has character istics that make it
suitable for driving on mud and
snow .

@Composition of the tire cord
and materials
The number of plies indicates the
number of rubberized fabric lay­
ers in the tire. In general: the
more layers , the more weight a
tire can carry . Tire manufacturers
must also specify the materials
used in the tire. These inc lude
steel, nylon, polyester and other
materials.
@ Maximum permitted load
This number indicates the max i­
mum load in kilograms and
pounds that the tire can carry.

Glossary of tire and loading
terminology
Accessory weight
means the comb ined weigh t (in
excess of those standard items
which may be replaced) of auto­
matic transm ission, power steer­
ing , power brakes, power win­
dows, power seats, radio, and
heater, to the extent that these
items are available as facto ry-in­
stalled equipment (whether in ­
stalled or not) .
Aspect ratio
means the ratio of the heigh t to
the width of the tire in percent .
Numbers of 55 or lowe r indicate a
low sidewa ll for improved steer­
ing response and better overall
handling on dry pavement. .,.

Ma ximum (permissible)
inflation pressure
means the maximum cold infla­
tion pressure to which a t ire may
be inflated. Also called "maxi ­
mum inflation pressure."
Normal occupant weight
means 150 lbs. (68 kilograms)
times the number of occupants
seated in the veh icle up to the to­
tal seating capacity of your vehi­ c le.
Occupant distribution
means distribution of occupants

increase the risk of the loss of
vehicle control.
- The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­
tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas ­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload­
ed.
Wheels
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard
(tire inflation pressure label)
~ page 227, fig. 190.
2.
Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers
from
" XXX " kilograms or "XXX "
pounds shown on the sticker
¢page 227, fig. 190.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex­
ample, if the
" XXX " amount
equals
1400 lbs. and there will
be five
150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage load capacity is
650 lbs.
(1400-750 (5 X 150) = 650
lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.
