Steering lock
The steering locks when you turn the engine
off using the
I STAR T ENGINE ST OP I button
and open the driver 's door. The locked steer­
ing helps prevent vehicle theft.
A WARNING
-
- Never allow the engine to run in conf ined
spaces -danger of asphyxiat ion .
- Never turn off the engine until the vehi­
cle has come to a complete stop .
- The brake booster and power steering
only work when the engine is running.
If
the engine is off, you have to use more
force when steering or brak ing. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serio us injuries.

220 Check ing and filling
- 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 persona l 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 repa ir
with the engine running:
- First, fully apply the parking brake,
move selector lever to "P" (Park) .
- Always use extreme caution to prevent
clot hing, jewe lry, 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
start ing, and do not wear cloth ing that
will hang or d roop into the eng ine.
- Min imize exposure to emission and
chem ica l hazards c:> &. .

- If you notice while driv ing that the hood
is not secured properly, stop at once and
close it.

224 Check ing and filling
With all these variab les coming in to p lay, no
standard rate of oil consumption can b e es­
tablished or specif ied. There is no alternative
to regular and frequent checking of the oi l lev­
el, see
Note .
If the ye llow engin e oi l level warning symbol
in the instrument cluster
1\1 li ghts up, you
should check the o il level as soon as possible
¢
page 224 or ¢ page 225. Top off the oil at
your earliest convenience¢
page 225.
A WARNING
Before yo u check anything in the engine
compartment, always read and heed all
WARN INGS
¢ .&. in Working in the engine
compartment on page
219.
(D Note
Dr iving with an insuffic ient oi l level is like­
ly to ca use seve re damage to the eng ine .
{D) Tips
-The oil pressure warning display. is
not an indicator of the oil lev el. Do not
r ely on it . Instead, check the oil level in
your engine at regular intervals, pref ­
erably ea ch time you refuel , and always
befor e going on a long trip .
-If yo u have the impres sion you r engine
consumes excessive amo unts o f oi l, we
r ecommend that yo u consult your Audi
dealer to have the ca use of yo ur concern
properly diagnosed . Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time . Your Audi dealer has in­
str uctions about how to measure oil con­
sumption accurate ly .
Checking the engine oil level

Depend ing on the way the vehicle is dr iven
and t he ope ra ti ng cond it ions, oi l consu mption
can be up to 1/ 2 quart pe r 600 miles (0 .S liter
per 1,000 km) . Consumption may be hig her
within the first 3,000 miles (S ,000 km) .
(D Tips
The oil leve l indic ato r in t he MMI Disp lay is
on ly an information display.
If the oi l level
i s low, a minimum oil war ning appea rs in
the instr ument cluster. Add oil
¢
page 225. If the hood has been opened,
the cur rent oil level is shown in t he instru­
ment cluster the next t ime the ignition is
swi tched on.

228 Checking and filling
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 221.
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 15 will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor , we
still recommend 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 .
(D 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 219.
.. Turn off the engine .
.. Let the engine cool down.
.. Place a thick rag over the coolant expansion
tank
¢ page 227, fig . 179 and carefully
twist the cap counter-clockwise ¢,&. .
.,. Add coolant.
.. Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications
¢ page 22 7, Coolant. We
recommend using only coolant additive G12+
+, G3 or in an emergency G12+ . Do
not use a
different additive. In an emergency use plain
water 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.
