ABS AUDI S7 2016 Owner's Manual

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,

different tire speeds. For this rea­
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular tires.
A 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 6 years old when abso-
Wheels
lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle . Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

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

_& WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­

Tire pressure monitoring
system
CD General notes
Each tire, includ ing the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your veh icle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you shou ld determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­ ly under -inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as poss ible, and inflate
them to the proper pressure. Driving on a signifi­ cantly under-inflated tire causes the tire to over­
heat and can lead to t ire failure. Under-inflation
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
sponsib ility to ma inta in correct tire pressure,
even if under-inflation has not reached the level
to trigger illuminat ion of the TPMS low t ire pres­
sure telltale.
Your vehicle has also been equ ipped 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
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated . This sequence will cont inue upon
Wheels
subsequent vehicle 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
i nsta llation 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 t ires or wheels on your veh icle to ensure
that the replacement or alternate t ires and
whee ls allow the TPMS to continue to function
properly.
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 .
Fig. 199 Instrument cluster: indicator 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
t ir es, this is indicated in the instrument cluster
display with an indicator light
HE and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he 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 rep lacing a tire on
your vehicle
¢ page 252. The ti re pressure moni­
toring system only monitors the tire pressure you have stored. Refer to the tire pressure label for ..,.
