2010 AUDI Q7 coolant

_____________________________________________ C_h _ e_ c_ k_in --= g:-. a_n _d_ f_i _ll _i_n -=g =-- ____.•
- We recommend using only coolant additive Gl2 ++ (check the
l a bel) for yo ur vehicle. This coolant ad dit ive is available at au tho·
r ized Audi dealers . Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
eng ine coo lant . Adding radiator repa ir fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant Level
The engine coolant level can be checked with a quick
glance .

Before you c heck anything in the eng ine compartment,
always read and heed all WARNINGS~ & in "Working in
the e ngine compartment" on
page 297.
- Turn off the ignit ion .
- Let t he eng ine cool down .
- Place a thick rag over the coolant expans ion tank
~ fig . 235 and carefully twist the cap counter ·clockwise
~ & -
Vehicle OP-eration
-Read the engine coolant level in th e open coo lant expan ·
sion tank ~ fig . 235 . With a cold engine, the coolant level
should be between the "min" and "max" ma rkings . Whe n
the engine is warm , the level may be slight ly above the
"max" marking .
The location o f the coo lant expansion tank can be seen in the engine
compartment illustration=>
page 298 .
To obt ain an accurate reading , the engine must be sw itched off.
Th e expans ion t an k in your vehicle is equippe d with an electric coolant
level sensor.
When the coolant lev el is too low, the warning light in the Auto·Check
System=>
page 30 will blink until you add coolant and t he level has
been resto red to normal. Even though there is an electric coolant
level sensor, we st ill recommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling system . In the event of
coo lant loss , the cooling system sho uld be inspected immed iate ly by
your authorized Aud i dea ler . It is not enough mere ly to add coolant.
In a
s ealed system, losses can occu r only if the boiling point of the
coolant is exceeded as a result of ove rheating .
& WARNING
The cooling system is under pressure and can get ve ry hot. Reduce
the ri sk of scalding from hot coolant by following the se steps.
• Turn off the engine and allow it to cool down .
• Protect your face, hand s and arms from e scaping fluid and
s team b y co ve ring the cap with a large, thi ck r ag.
• Turn the cap slowly and ver y carefully in a counter-clo ckwise
direction whil e applying light , downward pre ssure on the top of
thecap .

& WARNING (conti nu ed )
• To avoid being burned, do not spill antifreeze or coolant on the
exhaust system or hot engine part s. Under certain condit ion s, the
ethylene glycol in engine coolant can catch fire.

Do not add any type of radiator leak sealant to yo ur vehicle's engine
c oo lant. Addi ng radia tor repa ir fluid m ay adverse ly affe ct the func­
tion and performance of your cooling system and could result in

Adding coolant
Be very careful when adding engine coolant.
Before you check anyt hing in th e eng ine co mpart ment ,
always read and heed all WARNINGS => & in "Wor king i n
t h e e ngine compa rtment" on
page 297.
- Tur n off the eng ine.
- Let t he engi ne c ool d ow n.
- Place a thic k rag over th e coolan t expans ion tank
=> pag e 305, fig. 235 and carefully twist t he cap cou nter ­
cl ockwi se
=> &.
- Add coo lant.
- Tw ist the ca p on aga in
tightly .
Replacement eng ine coolant must conform to exact specifications
=>
page 304, "Coolant". Even in a n emergency, if coolant addi tive
Gl2 ++, Gl2 + or Gl2 is not available, do not use a different addit ive.
Use plain wate r in st ead until you can get the cor rec t additive an d can
restore the correct ratio. This shou ld be done as soon as possible. If
you have lost a considerable amount of coolant, then you sho uld
a d d c old an tifr ee ze and cold wa ter only when the e ngine is cold.
Always use
new engine coo la nt when refilling.
Do not fill coolant above the "MAX" mark. Excess coolant will be
fo rced o ut thr ough the p re ssur e relief v alve in the c ap w hen the
eng ine becomes hot.
& 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
s team by covering the cap with a large, thi ck rag .
- Turn the cap slowly and very carefully in a counter-clockwise
direction while applying light, downward pre ssure on the top
of the cap.
- To avoid being burned, do not spill antifreeze or coolant on
the exh aust system or hot engine parts . Under certain condi­
tions , the ethylene glycol in engine coolant can catch fire.
• Antifreeze is poisonous. Always store antifreeze in its original
container and well out of the reach of children.
• If you drain the coolant , it mu st be caught and safely stored in
a proper container clearly marked "poison ".
0 Note
• Coolant poll utes the environment and could cause an engine fire.
Excess coolant w ill be forced o ut thro ugh the pressure relief va lve in
t he c ap when t he e ngine becomes hot.
• If, i n an emergency, only water can be added, the co rrect ratio
between wate r and an tifreeze=>

After you switch the engine off, the auxiliary fan can continue r unning
for up to 10 minutes -eve n w it h t he igni tion o ff.
It can even swit ch on
again later by itse lf => & , if
• t he tem pera ture of the e ngi ne coola nt rises due to the hea t build­
up from the eng ine in the engine compa rtment, o r
• th e engine compar tmen t heats up because the ve hicl e is parked in
intense s unlight.
& WARNING
• To reduce the risk of personal injury never touch the radiator
fan .
• The auxiliary electric fan is temperature cont rolled and can
switch on suddenly even when the engine i s not running.
• The auxiliary radiator fan switche s on automatically when the
engine coolant reaches a certain temperatu re and will continue to
run until the coolant temperature drops. •

- Lift the filler cap tongue to add washer fluid . You can fill
the container to the top .
- Press the cap back onto the filler neck after filling the container.
You can find the reservoir capacit y in the table in=:> page 363.
To prevent lime residue from bu ilding up on the spray jets, use
distilled water when refilling. Always add a g lass cleaner so lution
(with frost protection in the w inter) .

& WARNING (conti nu ed )
• The engine compartment of any motor veh icle is a potentially
hazardous area . Never reach into th e area around or touch the
radiator fa n. It is temperature controlled and can switch on
s uddenly -even when the engine is off and the ignition key has
been remo ved. The radiator fan switches on autom atically when
the coolant rea ches a certain temperature and will continue to run
until the coolant tempe rature drops.
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it i s neces sary
to work unde rne ath the vehicle. The jac k supplied with the vehicle
is not adequate for thi s purpose and could collap se cau sing
serious personal injury.
• If you must work underneath the vehicle w ith the wheels on
the ground , always ma ke sure the vehicle is on level ground , th at
the whe els are alway s securely blocked and that the engine cannot
be started .
• Always make sure the transmi ssion selector l ever (automatic
tran smission) is in "P" (Park position ) and the par k brake is firmly
applied.
W For the sake of the environment
• Changing the engine settings will adversely affect e miss io n levels.
Th is is detrimenta l to the environment and increases fuel consump­
ti on.
• Always observe enviro nmental regulations when disposing of old
eng ine o il, use d brake fl uid, dirt y engine coo lant, s pent ba tt er ies or
worn out t ires.
• Undep loyed a irbag modules and pretens ioners migh t be classified
as Perchlorate Mater ia l -spec ial handling may apply, see
