2016 AUDI A7 ESP

Checking and F ill in g
Battery
General information
Under no rmal operating conditions, the battery
in your Audi does not need any ma intenance.
W ith
high outside temperatu res or long daily
d rives we recommend that you have the electro­
lyte level checked by a service facility . The elec­
trolyte level should a lso be checked each time
the battery is charged ¢
page 230.
Have the bat tery checked when you take yo ur ve­
hicle in for service . You are we ll advised to re­
p lace a battery that is o lder than 5 years .
W ith certa in types of airbag deploymen t, the bat­
tery is disconnected from the vehicle electrica l
system for safety reasons ¢
.&. in Repair, core
and disposal of the airbags on page 158.
Disconn ecting the battery t erminal s
Some veh icle funct ions (power window regula­
tors, for examp le) are lost if the battery termi ­
na ls are disconnected. These functions have to be
re learned after the battery terminals are con­
nected aga in. To prevent this, the battery shou ld
only be disconnected from the vehicle electrical
system when absolutely necessary for repairs.
Vehicl es not driven fo r long period s
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¢
page 194. Some
of the convenience funct ions may not operate,
such as the inter ior lights or power seat adjust­
ment. The convenience functions will be ava ilab le
again whe n you swit ch on the igni tion and sta rt
the engine.
Winte r operation
During the winter months, battery capacity tends
to decrease as temperatures drop . This is because
mo re power is also consumed w hile starting, and
the head lights, rear w indow defogger, etc ., are
used more often.
Avoid unnecessary power consumption, part icu­
larly in city traffic or when traveling only short
228
distances. Let your authorized Audi dealer check
the capacity of the vehicle battery before winter
sets in
¢ page 230 . 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 several
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.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor . Before you check anything
i n the luggage compartment,
re ad and he ed all

(D Note
Never use a fast charger as a booster to start
the engine . This w ill seriously damage sensi­
tive electron ic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery .
Intelligent energy management in your vehicle is
responsible for distributing the electrica l energy
throughout your vehicle
c:> page 194. The intell i­
gent energy management system will keep the
engine battery charged better than vehicles w ith­
out this system . To make sure the additional elec­
tr ical energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture only (the same as those installed at the
time your veh icle was delivered). Specif ications
are listed on the battery housing. Your author­
ized dealer must code the battery in the energy
management system to enable you to use the en­
e rgy management functions correctly after re­
p lacing the battery.
The new battery must have the same capacity ,
voltage (12-volts), amperage, construction and plug sealing .
When installing the battery, make sure the igni­
tion and all electrical consumers are switched off.
Make sure the ventilation hose on the s ide of
the battery is connected, otherwise fumes or
battery acid can leak out.
- Vehicles with the Start-Stop-System* are equipped with a special cycle-proof AGM battery. Installing a different type of bat­
tery can cause problems in the vehicle elec­
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery.
Checking and Filling
{® For the sake of the environment
Because of the prob lem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfur ic acid and lead and must
always be disposed of properly in compliance
with all environmental regulations. Disposing
of vehicle batteries improperly is very danger­
ous to the environment.

an authorized Audi dea ler or au­
thorized repair fac ility. These fa­
cilities have the proper knowledge
and are equipped with the re­
quired tools and replacement
parts.
.,. New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds fo r the first 350 miles
(500 km) with new tires .
.,. Use tires of t he same constr uc­
tion, size (rolling c ircumference)
and as close to the same tread pattern as possible on all four
wheels.

.,.Do not replace tires individ ually .
At least re place both t ires on the
same axle at the same time.
.,. A udi recommends that you use
Aud i O riginal equipment tires . If
you wo uld li ke to use different
tires, please note that the tires may perform d ifferently even if
they are the same s ize

.,. If you would like to equip you r
vehic le with a tire/rim combina­
tion that is different from what
was installed at the facto ry, con ­
sult w ith an authorized Aud i
dealer or authorized repair facili­
ty be fore making a purchase
¢ .&_ .
The spare tire* is d ifferent from
the regular t ires installed on the
vehicle -for example, if winter
tires or wi de tires are installed -
then only use the spare tire* tem­
porar ily in case of emergency and
drive carefully while it is in use . It
s h o u ld be replaced w ith a regular
tire as soon as poss ib le.
On
all wheel drive ve hic les, all
four wheels must be equipped
w ith tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by

Wheels
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.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1.6 mm) high
"wear indicators" ~fig.
196 run­
ning across the tread . Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear in­
dicators.
The t ires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones ¢&..
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice ver­
sa. This will allow the tires to

have approximately the same
length of service life.
For unidirectional tires, make sure
the tires are installed according to
the running direction indicated on
the tire sidewall¢
page 259.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hid­
den . Unusual vibrations in the ve ­
hicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately .
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized repair facility to have the vehicle inspected.
&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving
through water, when driving

Wheels
-These tires may wear more quickly than others .
- Please also remember that, wh ile these ti res
deliver responsive handling, they may ride less
comfortably and make more noise than other
choices.
Reduced performance in winter/cold season
conditions
All tires are designed for certain purposes. The
low aspect ratio, ultra high performance tires
originally installed on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for cold, snowy or
icy weather conditions. If you drive under those
circumstances, you should equip your vehicle
with all-season or winter tires, which offer better
traction under those conditions. We suggest you
use the recommended snow or all-season tires
specified for your vehicle, or their equivalent.
Refer to ¢
page 248 for more detailed i nforma·
tion regarding winter tires .
Uniform tire quality grading
-Tread wear
- Traction AA A BC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width¢
page 233, fig. 195 .
For example: Tread wear 200, Traction AA, Tern·
perature
A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov·
ernment test course.
For example, a tire graded 150 would wear one
and one half (11/2) times as well on the govern·
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however , and
may depart significantly from the norm due to
250
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der controlled conditions on specified govern ­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
¢ _& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire 's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate·
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure ¢& .
The grade C corresponds to a level of perform·
ance which all passenger car tires must meet un·
der the Federal Motor Vehicle Safety Standard
No. 109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
-
The traction grade assigned to th is tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor·
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla·
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
-
possible tire failure. ..,_
