2013 AUDI TT coolant reservoir

-Apply the parking brake.
- Move selector lever of automatic trans-
mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine cool down . Hot
components 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
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully 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 auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­ ant 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 electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury 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:
Checking and filling 181
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V -belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and wear no clothing that will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~,& .

-To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­ tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
- Coolant pollutes the environment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze¢
page 187 must be re­
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
The electric radiator fan is controlled by ther­
moswitches that switch on and off depending
on coolant and engine compartment tempera­
tures.
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operation conditions.
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off.
It can even switch
on again later by itself
c::> &., , if
- the temperature of the engine coolant rises due to the heat build-up from the engine in
the engine compartment, or
Checking and filling 189
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

INGS c::> .&. in Working in the engine compart­
ment on page 180.
~ Read the brake fluid level from the brake
fluid reservoir
c::> page 182, fig. 134 . The
brake fluid level must be between the "MIN"
and "MAX" markings.
The brake fluid reservoir is located behind the
rear partition of the engine compartment on
the left side
c::> page 182.
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads. This is not cause for alarm.
