Description
The indicator lights in the instrument cluster

you check anything in the engine compart­
ment, stop the engine and let it cool down.
Always exercise extreme caution when work­
ing under the hood ¢

9:::1: Engine oil pressure
The red engine oil pressure warning symbol re­
quires immediate service or repair . Driving with a
low-oil-pressure indication is likely to inflict se­
vere damage to the engine.
• Turn off engin e! Oil pressure too low
If the indicator light t urns on and the message
appears, the oil pressure is too low.
• Pull
off the road.
• Stop the vehicle .
• Turnoff the engine.
• Check the engine oil level ¢ page 195.
• If the engine oil level is too low, add engine oil
¢ page 195. Make sure that the o il pressure
warning symbol. appears no longe r in the
display before you start dr iving again.
• If the engi ne oil leve l is correct a nd the ind ica­
tor light st ill turns on, turn the eng ine
off and
do not continue driving . Seek p rofess ional as ­
s istance .
(D Tips
- The engine oil pressure symbol. is not
an indicator for a low engine oil level. Do
not rely on it. Instead , check the oil level in
your engine at regular intervals, prefe rably
each time you refuel, and always before
going on a long trip.
- The yellow oil level warning indication
Ill
requires oil refill or workshop service with ­
out delay. Do not wait until the red oil pressure warning. starts to flash before
you respond to the low oil leve l warning
Ill . By then , your engine may already have
suffered serious damage.

-L Engine cooling system
A malfunction in the engine cooling system must
be repaired as soon as possible .
• Turn off eng ine and check coolant level
If the indicator light turns on and the message
appears, the coolant temperature is too high o r
the coo lant leve l is too low.
• Pull
off th e roa d.
• Stop the vehicle.
• Tur noff the engine .
• Check coolant leve l
¢page 197.
• Add coo lant if necessary ¢ page 198.
• Continue dr iv ing o nly after the engine coolant
warning/ indicator light goes out .
• Contact your autho rized Aud i dealer for assis-
tance if necessa ry.
If the engi ne coo lant level is correct, t hen the ra ­
dia to r fan may be the cause o f th e malfunct io n.
• Coolant temperature! Let engine run with
v ehicle stationary
If the indicator ligh t turns on and the message
appears, let the eng ine run at id le for a few mi ­
nutes to coo l down.
A WARNING
-- If your vehicle should brea k down for me­
cha nica l o r other reasons, pa rk at a safe d is­
tanc e from moving traffic, turn

Checking and F ill in g
blink until you add coo lant and the level has been
restored to normal. Even though there is an e lec­
tr ic coo lant level sensor, we still recommend you
check the coo lant level from t ime to time.
Coolant los s
Coolant loss may indicate a leak in t he cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A WARNING
The cooling system is under pressure and can
get very hot. Reduce the risk of scalding from
hot coolant by following these steps .
- Turn off the engine and allow it to coo l
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag .
-Turn the cap slowly and very carefully in a
counter-clockw ise d irection while applying
light, downward pressure on the top of the
cap.
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system or hot eng ine parts . Under ce rtain conditions,
the ethy lene g lycol in engine coolant can
catch fire.
{il) Note
Do not add any type of rad iator leak sealant
to your veh icle's engine coolant . Adding radia­
to r repair f lu id may adverse ly affect the func­
tion and performance of your cooling system
and could resu lt 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 compart­
ment,

Replacement engine coo lant must conform to ex­
act specifications ¢
page 196, Coolan t.
We recommend using only coo lant additive Gl2 +
+ , Gl3
or in an emergency Gl2+. Do not use a
different additive. In an emergency use plain wa­
ter unt il 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 considerab le amount of cool­
ant, then you should add cold antifree ze and cold
water only when the engine is cold.
Always use
new engine coo lant when refilling.
Do not fil l coolant above the "MAX " mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
from hot coolant by following these steps.
- Turn off the eng ine and allow it to coo l

- Protect you r face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap s low ly and ve ry carefully in a

Please note the important safe­
ty precautions regarding tire pressure¢
page 215 and load
limits¢
page 217.
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden tire failure,
including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids ""
