coolant temperature AUDI Q7 2013 Owner´s Manual

274 Che cking and filling
-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 coo l-
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
c:;, page 271 must be re­
stored as soon as possible .
@ For the sake of the environment
Dra ined 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 radiator fan is driven by the engine via the
V-belt . The viscous clutch regulates the speed
of the fan accord ing to t he temperature of the
coolant.
An auxiliary electric radiator fan* switches on
and off depending on coolant temperature
and other vehicle operating 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
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
_&. 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.

The brake fluid level m ust be be­
tween the "MIN" and "MAX" markings.
The brake fluid reservoir is located at the rear
part ition of the engine compartment on the
left side
c:;, page 266.
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads. This is not cause for alarm .
If the brake flu id level falls
considerably be­
low the
"MIN" mark, the brake warn ing/indi­
cator light ( U.S. models:
