2013 AUDI Q5 coolant reservoir

234 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission 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. 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: -
First, fully apply the parking brake,
move selector lever of automatic trans­
mission 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

&_ 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.
(D 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.

A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢&. in Working in the engine
compartment on page 233.
Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil .
The engine in your Audi is a sophisticated
power plant that was bu ilt to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera-
tion. .,..

24 2 Ch ecking and filling
-If you drain the coolant, it must be
caught and safely stored in a p roper
conta iner clearly marked "poison".
(D Note
- Coolant pollutes the env ironment 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¢
page 240 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 radiator fan is driven by the engine via the
V-be lt . 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
a nd off depending on coolant temperature
and other ve hicle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢&. , 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 veh icle is parked in intense sunlight.
_&. WARNING
- To reduce the r isk of personal injury nev­
er to uch the radiator fa n. -
The a uxiliary electric fan is temperat ure
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on a u­
tomatically when the engine coolant reaches a certai n temperature and will
continue to ru n until the coolant temper­
ature drops.
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

The fluid level may drop slightly afte r some

install batteries of the same type and manu­
facture only (the same as those installed at
the t ime your vehicle was delivered) . Specifi ­
cations are listed on the battery housing. Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­ rectly after replacing the battery .
If it is not possible to use a battery of this
type, the new battery must have the same ca ­
pacity, voltage (12 volts), amperage, con­
struction and plug sea ling .
When installing the battery, make sure the ig­
nition and all electr ica l consumers are turned
off.
(D Note
- Make sure the ventilation hose on the
s ide of the batte ry is connected, other­
wise fumes or battery acid can leak out .
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery . Installing a different type of
battery can cause problems in the vehi­
cle elec trical system. When replacing the
vehicle battery, always insta ll one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author ­
ized Audi dealer change the battery for
you. Batteries contain su lfuric acid and
lead and must always be disposed of prop­
erly in compliance with all environmental
regu lations . D isposing of vehicle batteries
improperly is very dangerous to the envi­
ronment .
