2016 AUDI S7 air condition

Checking and Filling
Do not fill coolant above the "MAX" mark. Excess
coolant will be forced out through the pressure relief valve in the cap when the engine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise direction while applying light, downward pressure on the top of
the cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire .
-Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children .
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
- Do not add coolant if the expansion tank is empty. Air could enter the cooling system
and damage the engine. If this is the case,
do not continue driving. Seek professional
assistance .
- Coolant pollutes the environment and could cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
in the cap when the engine becomes hot.
- If, in an emergency, only water can be add­
ed, the correct ratio between water and an­
tifreeze
¢ page 224 must be restored as
soon as possible.

-
® For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulations.
Radiator fan
The radiator fan switches on automatically by it­
self
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
with the ignition off. It can even switch on again later by itself ¢& . if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal injury never
touch the radiator fan.
- The auxiliary electric fan is temperature con­
trolled and can switch on suddenly even
when the engine is not running.
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops. -

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

~ Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
~ Note the maximum permitted speed when driv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Snow chains not only improve the driving in win­
ter road conditions, but also the braking.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
i z ed repair facility to see if you may use snow
chains .
You must remove the chains when driving on roads that are free of snow. When roads are free
of snow, snow chains can impair handling and
damage the tires, and the chains will quickly be
destroyed.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con­
tact with them. Remove the wheel covers*
first. Use coated snow chains.
- Using snow chains that add more than 0 .4
inch (10.5 mm) of height can severely dam­
age the wheel housings and other vehicle
components.
- Do not install and use snow chains if there is
a malfunction in the adaptive air suspen­
sion*, because the vehicle height will be
very low. If you drive with snow chains any­
way, the wheel housings and other vehicle
components can be severely damaged.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra­
tio tires . These tires have been thoroughly tested
and been selected specifically for your model for
Wheels
their superb performance, road feel and handling
under a variety of driving conditions. Ask your au­
thorized Audi dealer for more details.
The low aspect ratio of these tires is indicated by
a numeral of
55 or less in the tire's size designa­
tion. The numeral represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Conventional tires have
a heigh t/width ratio of 60 or more.
The performance of low-aspect-ratio tires is par­
ticularly sensitive to improper inflation pres­
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should be checked at least once a month and always
before a long trip
~ page 2 43.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi­
ly by impact with potholes, curbs , gullies or
ridges on the road, particularly if the tire is un­
deri nflated.
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation pres­
sures. Check your tire pressure every 2,000
miles (3 ,000 km) and add air if necessary.
- Drive carefully on roads with potholes , deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause
damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest au­
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 miles (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of air and
underinflation, which could eventu ally cause
tire failure . If you believe that a tire may have
been damaged, replace the tire as soon as pos -
sible . .,.
