2015 AUDI A5 CABRIOLET ABS

Checking and F ill in g
The brake fluid reservoir is located at the rear
partition of the engine compartment on t he left
side ¢
page 197.
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 the b ra ke fluid level fal ls considerably below
the "MIN" mark, the brake warn ing/indi cator
light (U.S. models:
1111 , Canadian models: . )
will come on ¢
page 15. Do not contin ue to oper­
ate the vehicle . The complete brake system
should be thoroughly checked by an author iz ed
Aud i dealer or qualified workshop and the cause
corrected . If the brake fluid level is too low, the
brake warning/ind icator light w ill illuminate .
Contact an authorized Audi dealer
i mmed iately .
{D) Tips
The brake fluid reservoir is located under­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moist ure from the a ir. If the
water content in the brake fluid is too high, cor­ rosion in the brake system may result after a peri­
od of time . The boiling point of the brake flu id
w ill also decrease conside rably and dec rease
b rak ing perfo rmance.
Therefore, the brake flu id must be changed
e ve ry
two year s.
Always use new brake fluid w hich con­
forms to Fede ral Motor Vehicle Standard "FMVSS
1 16 DOT 4".
The brake fluid rese rvoir can be difficult to reach,
therefo re , we recommend that you have the
b rake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct too ls , the
right brake fluid and the know-how to do t his for
you.
A WARNING
- B rake fluid is poisonous. It must be stored
on ly in the closed original container out of
the reach of children!
204
- Brake fail ure can resu lt from o ld or inappro­
priate brake fluid. Observe these precau ­
tions:
- Use only b rake fluid that meets SAE spec i­
f ica tion
J 170 3 and conform s to Federa l
Motor Vehicle Standard 116. Always check
with yo ur autho rized Audi dea le r to make
su re you are using the correct brake fl uid.
The correct type of brake flu id is also ind i­
cated on the brake fluid reservoir.
- The brake fl uid must be new. Heavy use of
the brakes can cause a vapor lock if the
brake f luid is left in the system too long.
This can seriously affect the efficiency of
the brakes as well as your safety. This
could result in an acc ident.
(D Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the env ironment
Because of the prob lem of prope r disposal of
brake fluid as well as the special tools re­
qu ired and the necessary expert ise, we rec­
omme nd that you have the brake flu id
changed by you r autho rized Aud i dea le r.
Battery
, General information
U nder normal operating conditions, the battery
i n your Audi does not need any maintenance.
Wi th
high outside temperatures or long daily
drives we recommend that you have the e lectro ­
lyte level checked by an a uth orized Aud i deale r o r
qualified workshop . The electrolyte leve l should
a lso be checked each time the batte ry is c ha rged
~ page 206.
Have the battery checked when yo u take your ve­
hicle in for service . You a re well adv ised to re­
pla ce a battery that is older tha n 5 years.
With certain types of airbag deployment, the bat ­
te ry is disconnected from the veh icle elect rical
system for safety reasons
¢ & in Repair, care
and disposal of the airbags on page 1 45.

Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors , for example) are lost if the battery termi­
nals are disconnected. These functions have to be
re learned after th e battery terminals are con­
nected again. To prevent this, the batte ry should
only be disconnected from the ve hicle electrical
system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­ pability over a longer period
c:> page 175 .
Some of the conven ience functions may not oper­
ate, such as the interior lights or the power seat
adjustment. The convenience functions will be
available aga in when you turn on the ignition and
start the engine.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop. This is because
more power is also consumed while s tart ing, and
the headlights, rear window defogger, etc ., are
used more often .
Avoid unnecessary power consumption, part icu­
larly in city traffic or when traveling only short
d istances . Let your authorized Aud i dealer check
the capacity of the vehicle battery before w inter
sets in ¢
page 206 . A well charged battery will
not only prevent starting problems when the
weather is cold, but will also last longer.
(D Tips
If your vehicle is left standing for severa l
weeks at extremely low temperatures, the ve­
hicle battery should be removed and stored
where it will not freeze. This will prevent it
from being damaged and having to be re­ placed.
Checking and Filling
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
men t under the floor. Before you check anything
in the luggage compartment ,
read and heed all
WARNINGS
c:> .&_ .
Always heed the safety warnings, when working
on the vehicle battery or the vehicle electr ical
system to prevent injury .
The following WARNINGS are very important
when working on the battery :
Always heed the following WARNING SYM-
BOLS and safety precautions when working on
the battery.
®
Always wear eye protection.
A
Battery acid contains sulfuric acid. Al-
ways wear gloves and eye protection.
@
No
- sparks
- flames
- smoking.
~
When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
®
Always keep the battery well out of reach
of children.
A WARNING
= -
Whenever working on the battery or on the
e lectr ical system, there is the risk of injury,
accident and even f ire. Read and heed the fol ­
lowing WARNINGS:
- Always wear eye protection . Do not let bat­
tery ac id or any lead particles get on your
skin or clothing. Shield your eyes. Exp losive
gases can cause blindness or other in jury.
- Battery acid conta ins sulfuric acid . Sulfuric
acid can cause blindness and severe burns.

_& WARNING -
-Only use tire/rim combina­tions 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 6 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

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 repair facility
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.

also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low tire pressure telltale . When the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent veh icle start-ups as long as the mal­
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.

If the Tire Pressure Monitoring System
indicator appears
Appl ies to vehicles : wi th t ir e p ress ure mo nito rin g system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 183 Instrument cluster: i ndicator light with message
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires .
If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message .
If only one tire is affected, the location of that
tire will be indicated .
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ¢
page 228. The tire pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
r=> page 219, fig . 182.
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low .
- the tire has structural damage.
- the tir e was replaced or the tire pressure was
changed and it was not stored ¢
page 228.
