2013 AUDI Q7 coolant temperature

-Apply the parking brake.
- Move selector lever to "P" (Park).
- 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. Wa it 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 265
- First, fully apply the parking brake,
move selector lever to "P" (Park) .
- 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 do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
Q) Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age 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 flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer. •

272 Che cking and filling
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31° F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.
_& WARNING
-
Before yo u check anything in the e ngine
compar tment, alw ays read and heed all
WARN INGS
¢.&. in Working in the engine
compartment on page 264 .
(D Note
- Befo re win ter se ts in, have the coolan t
che cked to see if t he coolant ad dit ive in
you r vehicle is s ufficien t to mee t the cli ­
mate conditions. T his is especially impor­
tant if yo u live in a region where the w in­
ter is extremely co ld. If necessary, in­
crease the proport io n of coolant additive
to 60%.
- When adding coolant addit ive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G1 2++ o r G13 fo r your vehicle.
Thi s coo lant add itive is available at au­
thorized A ud i dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The res ulting corro ­
sion can cause a loss of coo lant and se­
r ious eng ine damage.
- Do not add any type of radiator leak sea l­
ant to your ve hicle's engine coo lant.
Adding rad iator repair fluid may adve rse­
ly affec t the function and perfo rmance of
you r cooling system and could result in
damage not cove red by your New Vehicle
Limited Wa rranty.
Checking the engine coolant level
T he engine coolant level can be checked with
a quick glance .

Befo re you check anyth ing in the en gine com­
partment,
alway s read and h eed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 264.
.,. Park yo ur vehicle on a level surf ace .
.,. Tur n off the ignition.
.,. Let the engine cool down.
.,. Place a thick rag over the coolant expansion
tank ¢
fig. 24 7, ¢ page 266, fig . 243 and
carefull y twist the cap counter-clockwise
¢,&. .
.,. Read the engine coolant level in the open
coo lant expansion ta nk. W ith a cold eng ine,
the coolant level should be between the "min " and "max " mar kings. When t he en­
g ine is wa rm, the level may be slightly above
the "max" mark ing.
T he locat ion of the coo lant expansion tan k
c an be see n in the engine compartmen t illu s­
t ration
¢ page 266.
T o obtain an accu rate reading, the engine
must be switched off.
The expansion tank in your veh icle is equipped
with an electr ic coo lant level senso r.
When the coolant leve l is too low, the warning
light in the Auto-Check System¢
page 32 will
blink unti l you add coolant and the level has
been resto red to normal. Even though there is
an electric coo lant level senso r, we still rec­
ommend you check the coolant level from
time to t ime .

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.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

The brake fluid reservoir is located at the rear
part ition of the engine compartment on the
left side

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:
