2015 AUDI Q5 radiator

Warning light in th e instrument clus ter
di splay
If the . warning light in the instrument cluster
display flashes , this can mean one of two th ings:
either the coolant
t emperature is too high, or the
coolan t
level is too low 9 page 29.
If the needle is well in the upper area of the
gauge, the coo lant temperature is too high.
S top
the veh icle , switc h the engin e off, and allo w i t
to coo l.
If the warning light comes on again after
driving a short distance , contact an authorized
Aud i dealer or other q ualified workshop .
..&, WARNING
-Always observe the warni ng i n 9 page 221,
before opening the hood and chec king the
engine coolan t level.
- Never open the engine hood if you see o r
hear steam, or if you see engine coolant
dr ipping from the engine compartmen t. You
cou ld burn yourself . Let the engine cool off
first so that you cannot hear o r see any
steam or engine coo lant.
CD Note
- M ount ing additional lights or accesso ries in
front of the air inlets red uces the cooling ef ­
fect of the radiator . At high outside temper ­
atures or high engine load, the eng ine could
overheat .
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving . If the spoiler is damaged, this
could reduce the cooling effect and the en­
gine could then overheat. Ask your author ­
i zed Audi dealer for assistance .
Tachometer (engine rev counter )
The tachometer indicates the engine RPM (revo ­
lutions per minutes) .
If engine RPM drops below 1,500 , you should
downshift to the next lower gear. The red area at
~ the end of the scale indicates max imum perm is -co
~ sible eng ine RPM after the break- in period . Be-

Steering lock
The steering locks when you remove the ignition
key. The locked steering helps prevent vehicle
theft.
Emergency off
If it is necessary in unusual circumstances, the
engine can be switched off while the vehicle is
moving. The engine will be switched off if you
press on the key for an extended period.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if necessary . Be­
cause you cannot steer and brake as you
usually would, this could lead to crashes
and serious injuries.
- For safety reasons, you should always park
your vehicle with the selector lever in P. Oth­ erwise, the vehicle could inadvertently roll
away.
- The radiator fan can continue to run for up
to 10 minutes even after you have turned off the engine and removed the ignition key .
The radiator fan can also turn on again if the
engine coolant heats up because of intense
sunlight or heat build-up in the engine com­
partment .
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- Never leave children or persons requiring as­
sistance unattended in the vehicle. The
doors can be locked using the remote trans­
mitter, preventing people from escaping
from the vehicle on their own in the event of
an emergency. Depending on the time of
year, people inside the vehicle can be ex­
posed to very high or very low tempera­
tures.

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

('.!) Note
When adding fluids, always make sure that
they are poured into the proper container or
filler opening, otherwise serious damage to
vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If you
see spots from oil or other vehicle fluids, have
your vehicle inspected by an authorized Audi dealer.

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,
always read and heed all WARNINGS
228
c::> A in Working in the engine compartment on
page
221.
Requirement: There must be a residual amount
of coolant in the expansion tank
<=>(i) .
"'Turn off the engine.
"' Let the engine cool down.
"' Place a thick rag over the coolant expansion
tank
c::> page 22 7, fig. 200 and carefully turn
the cap counter-clockwise
c::> .&, .
"'Add coolant mixed in the correct ratio
c::> page 22 7, 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 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.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a quick
glance .
