2015 AUDI Q5 engine coolant

Checking and Filling
-Always let the engine cool down. Hot com­
ponents will burn skin on contact .
- To reduce the risk of being burned, never
open the hood if you see or hear steam or
coolant escaping from the engine compart­
ment . Wait until no steam or coolant can be
seen or heard before carefully opening the
hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents . They can cause a fire .
- Never touch the radiator fan. The auxiliary
electric fan is temperature controlled and
can switch on suddenly.
- Never open the coolant reservoir cap when
the engine is still warm. The coolant system
is pressurized and hot coolant could spray
out .
- Protect your face, hands and arm from steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary :
- Always disconnect the battery.
- Never smoke or work near heaters or open
flames . Fluids in the engine compartment
could start a fire.
- Keep an approved fire extinguisher imme­
diately available.
- To avoid electrical shock and personal injury
while the engine is running or being started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake , move
selector lever of automatic transmission
to P (Park).
222
- Always use extreme caution to prevent
clothing, jewelry, or long hair from getting
caught in the radiator fan, V-belts or other
moving parts, or from contacting hot
parts . Tie back hair before starting, and do
not wear clothing that will hang or droop
into the engine.
- Minimize exposure to emission and chemi­
cal hazards

Cooling system
Coolant
T he engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
qu ires little attention .
T he cooling system has been filled at the factory
with a permanent coolant which doe s not need to
be changed . T he cool ant consists of a mixture of
specia lly condit io ned water and the ma nufactur ­
e r's g lycol-basedcoo lant additive G 13 antifreeze
w ith a nticorros ion add itives (50% for USA mod­
e ls; 60% for Canadian models) . Thi s m ixt ure bot h
a ssures the ne cessary frost protection and pro­
tec ts meta l components in the engine 's cooling
system from corrosion and sca ling. It a lso raises
the boiling point of the coolant.
D o not red uce the conce ntra tion o f th e coo lant i n
the summer by add ing p la in wa ter.
The propor­
tion of coolant additive must be at least 50% but not more than 60 %
to maintain antifreeze
protection and cooling efficiency . If the coolant
frost protection is too low, the coolan t could
freeze and damage t he vehicle heat ing and en­
g ine cooling system .
For yea r-round driving, antifree ze is added at the
factory for tempe ratu res down to:
- -31°F ( -35°C) USA
- - 4 0°F ( - 40°C) C anada .
I f yo u mu st add coo lant, use a m ixt ure of wate r
a nd coolant add it ive. Mixing the coolant additive
with d istilled water is recommende d.
_& WARNING
Be fore yo u check any thing i n the engine com ­
par tment, always read and hee d all WAR N-
Checking and Fillin g
IN GS ¢ .& in Working in the engine compart­
ment on page 221.
@ Note
- Be fore winte r sets in , have the coo lant
checke d to see if the coolant additive in you r
vehicle is sufficient to meet the climate con­ diti ons. This is espec ia lly important if you
live in a region where the winter is extreme­
ly cold . If necessary, increase the p ropo rtion
o f coolan t addi tive to 60%.
- Whe n adding coolant additive to your cool­
ing system, remember :
- We recommend using o nly coo lan t add i­
tive G12++ o r G13 fo r yo ur vehicle . This
coolant ad dit ive is available at author ized
A ud i dealers . Othe r types of antifreeze ca n
significantly reduce cor rosion protect ion .
The resulting cor rosion can ca use a loss of
coolant a nd serious e ngine damage .
- Do not add any type of rad iator leak sealant
to your vehicle's engine coolant. Adding ra­ diat or repa ir flu id may adverse ly affect the
function and perfo rmance of your cooling
system and cou ld result i n damage not cov­
ere d by your New Vehicle Lim ited W arra nty .

Checking and Filling
"'Park your vehicle on a level surface.
"'Turn off the ignition.
"'Read the engine coolant level from the coolant
expansion tank
c:> fig . 200, <=> page 223,
fig. 197. With a cold engine, the coolant level
should be between the "MIN" and "MAX" mark­
ings . When the engine is warm, the level may
be slightly above the "MAX" marking .
The location of the coolant expansion tank can be
seen in the engine compartment illustration
<=> page 223 .
To obtain an accurate reading, the engine must
be switched off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System
c::> page 29 will
blink until you add coolant and the level has been
restored to normal. Even though there is an elec­
tric coolant level sensor, we still recommend you
check the coolant level from time to time .
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 coolant is exceeded as a re­
sult of overheating.
0 Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding 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,

Replacement engine coolant must conform to ex­
act specifications
c::> page 22 7, 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 cool­
ant, then you should add cold antifree ze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
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 spi ll 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 conta iner and well out
of the reach of ch ildren .
-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 eng ine .
If this is the case,
do not continue driving. Seek profess ional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire . Excess coolant will be
fo rced out through the pressure relief valve
i n the cap when the eng ine becomes hot.
- If, i n an emergency , only water can be add­
ed, the correct ratio between wa ter and an­
tifreeze
~ page 22 7 must be restored as
soon as possib le .
@) For the sake of the environment
Drained coolant should not be reused. Always
dispose o f used coolant while observ ing all
environmental regulations .
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
be lt . The viscous clu tch regulates the speed of
the fan ac cording to the temperature of the cool ­
ant.
An auxiliary e lectr ic rad iator fan* switches on and
off depend ing on coolant temperat ure and othe r
veh icle operating conditions.
Afte r you switch the engine off, the auxiliary fan
can continue runn ing for up to 10 minutes -even
Ch eck in g and Fillin g
with the ignition off . It can even switch on again
later by itself¢& , if
- the temperatu re of the engine coo lant rises due
to the heat build- up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
veh icle is parked in intense sun light .
A WARNING
-To reduce the risk of persona l 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 a uxiliary radiator fan sw itches on auto­
matica lly when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
lo ss of vehicle control , but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
