2012 AUDI A5 COUPE check oil

When the engine is warm, the level may be
slightly above the
"MAX" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢ page 239.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System ¢page
31 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized Audi dealer.
It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
& WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction while ap­
plying light, downward pressure on the
top of the cap.
- To avoid being burned, do not spill 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.
Checking and filling 245
@ Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage not covered by your New Vehicle limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢ & in Working in the engine compart ­
ment on page 23

.,. Turn off the engine .
.,. let the engine cool down.
.,. Place a thick rag over the coolant expansion
tank ¢ page
244, fig . 206 and carefully turn
the cap counter-clockwise ¢
&_.
.,. Add coolant.
.. Twist the cap on again tightly.
Replacement engine coolant must conform to
exact specifications ¢ page
244, Coolant.
Even in an emergency, if coolant addi-
tive G12++, G12+ or G12 is
not available, do
not use a different additive. Use plain water
instead until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible.
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot.

can get very hot. Reduce the risk of ...,

Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 295.
_&. WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the threads in the wheel hubs clean so the
whee l bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs.(± 10 Nm). Torque wheel bo lts

torque m ust be checked as soon as possi­
ble with a torque wrench -preferably by an
a uthori zed Audi dea ler or qualified work­
shop.
Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 258, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma inta in recommended inflation
pressu res. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces-
sary . .., •

fall f rom a lift if the re is a change in ve­
h icle we ight d istr ibut ion and balance.
This might happen, for examp le, when
heavy components such as the engi ne
b lock or transmiss io n are removed .
- Whe n removing heavy components like
these, ancho r vehicle to ho ist o r add cor­
r e spond ing w eig hts to ma intai n the cen ­
te r of g ravity . Othe rwise, the vehicl e

(D Note
- Be awa re of th e f ollowing po in ts b efore
li fting t he vehi cle:
- The vehicle should never be lifted or
jacked up from underneath the engine oil pan, the transmission housing, the
front or rear axle or the body side
members. This could lead to serious
damage .
- To avoid damage to the underbody or
chassis frame, a rubber pad must be
inserted between the floor jack and
the lift points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity
of the hoist.
- Before driving over a workshop hoist,
ensure that there is sufficient clear­ ance between the hoist and low parts
of the vehicle .
Emergency situations 289

•

-Always make sure the transm ission se­
lector lever (automatic transmiss ion) is
in "P" (Park position) or Neutral (manual
transmission) and the park brake is firm­
ly appl ied .
® For the sake of the environment
-Changing the eng ine settings w ill ad­
versely affect em ission levels. This is det­
rimental to the environment and increas­
es fuel consumption .
- Always observe env ironmental regula­
tions when d ispos ing of old engine oil,
used brake fluid, dirty engine coolant,
spent batter ies or worn out t ires.
- Undeployed airbag modules and p reten­
s ioners might be classified as Perchlo­
rate Material -special handling may ap ­
ply, see www.dtsc.ca .gov/hazardous­
waste/perch lorate . When the veh icle or
parts of the restraint system including
airbag modules safety belts with preten­
s ioners are scrapped, all applicable laws
and regulations must be observed. Your
authorized Audi dealer is familiar w ith
these requirements and we recommend
that you have your dealer perform this
serv ice for you .
