coolant reservoir AUDI Q5 2015 Owners Manual

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

-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 .
