2016 AUDI A6 ignition

• Park your vehicle on a level surface.
• Switch
off the ignition.
• Read the engine coolant level from the coolant
expansion tank¢
fig. 189, ¢ page 218,
fig. 186.
With a cold engine, the coolant level
should be between the "min" and "max" mark­
i ngs . When the engine is warm, the level may
be s light ly above the "max " marking.
The location of the coolant expans ion tank can be
seen in the engine compartment illustrat ion
¢pag e 218.
To obtain an accurate reading, the engine must
be sw itched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
c:> page 15 wi ll il­
luminate until you add coolant and the level has
been restored to normal. Even though there is an
e lectric coolant level sensor, we still recommend
you check the coolant level from t ime to t ime.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
In a
sealed system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing.
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 eng ine and allow it to cool
down.
- Protect your face, hands and arms from es­
caping 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.
Checking and Filling
-To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certain cond itions,
the ethylene glycol in engi ne coolant can
catch fire.
(D Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Add ing radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢.&. in Working in the engine compartment on
page 216.
• Requ irement: There must be a residual amount
of coolant in the expansion tank
c:> (D .
•Turnoff the engine .
• Let the engine cool down.
• Place a thick rag over the coolant expans ion
tank
c:>p age 222 , fig. 189 and carefully twist
the cap counter-clockwise
c:> _& .
• Add coo lant mixed in the correct ratio
c:> page 222, Coolant up to the MAX marking .
• Make sure that the fluid level remains stable.
Add more coolant if necessary.
• Twist the cap on again
tightly.
Replacement engine coolant must conform to ex ­
act specifications
c> page 222, Coolant.
We recommend using only coolant additive Gl2+
+ , Gl3
or in an emergency Gl2+. Do not use a
different additive. In an emergency use plain wa­
ter until you can get the correct additive and can
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of coo l­
ant, then you should add cold antifreeze and cold
water only when the engine is co ld.
Always use
new engine coolant when refi lling.

Check ing and F illing
@ For the sake of the environment
Because of the prob lem of proper disposal of
brake fluid as we ll as the special tools re­
quired and the necessary expertise, we rec ­
ommend that you have the b rake fluid
changed by your author ized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
W ith
high outside temperat ures or long da ily
drives we recommend that you have the electro­
lyte level checked by a service fac ility . The elec­
trolyte level should also be chec ked eac h time
the battery is charged ¢
page 228 .
Have the battery checked when you take your ve­
h icle in for service. You a re well advised to re­
p lace a battery t hat is o lder than S years .
W ith certain types of a irbag dep loyment, the
battery is disconnected from the vehicle electr i­
cal system for safety reasons
¢ &. in Repair, care
and disposal of the airbags on page 157 .
Disconnecting the battery terminal s
Some vehicle functions (power window reg ula­
tors, for example) are lost i f th e battery termi ­
na ls are disconnected. These functions have to be
relearned after the battery termina ls are con­
nected aga in. To prevent th is , the batte ry shou ld
only be disconnected from the vehicle e lectr ica l
sys te m when abso lutely ne cessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
seve ral days or weeks, electrical components a re
gradua lly cut back or sw itched off . T hi s reduces
e n ergy cons umption and ma inta ins starti ng ca­
pab il ity over a longer pe riod
¢ page 192. Some
of the conve nience f unct io ns may not o pera te,
such as the inter io r lig hts or powe r seat a dju st­
ment . The convenience funct ions wi ll be avai lab le
again when you switch on the ignition and start
the engine.

Winter operation
Dur ing the winte r mon ths, ba ttery c apacity tends
to decrease as tempe ra tu res drop . This is be ­
ca use mo re power is also consume d while start ­
i ng, and the headlights, rear window defogger,
etc., are used more often.
Avo id unne cessary powe r consum ption, pa rticu­
l arly in city traffic or when traveling on ly short
distances . Let your author ized Audi dealer check
t h e capacity of the vehicle battery before winter
sets in~
