using a screwdriver and remove the cover.
The coolant reservoir is located below
¢fig. 144.
Chec king the engine cool ant level
~ Place a rag or cloth on the cap of the cool­
ant expansion tank and turn the cap
careful­
ly
to the left (counter-clockwise) ¢ .&_.
~ Read the coolant level inside the coolant ex­
pans ion tank ¢
fig. 144 . With a co ld engine,
it must be above the "min" mark. With a hot
eng ine, it can be a little above the indicated
range.
T o obtain an accu rate reading, the engine
must be switched off.
The expansion ta nk in your vehicle is equ ipped
with an electric coo lant level sensor
¢page 15. We still recommend you check the
c oolant 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
i ng system shou ld be inspected immediately
by your aut horized Audi dea ler. It is not
eno ugh me rely to add coolant.
In a
s ea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a resu lt of overheating.

A WARNING ,~
- The cooling system is under pressure. Do
notopenthecapofthecoolantexpan­
sion tank when the engine is hot . You
risk being scalded .
- The coolant additive, and therefore the coolant itself, is hazardous to health.
Keep the coolant additive in the original
container out of the reach of children. It
is a poison hazard.
(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
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 169.
.. Add coolant .
.. Twist the cap on again
tightly .
.. Tighten the cap (D ¢ page 176, fig . 144
again.
Replacement engine coolan t must conform to
exact specifications ¢
page 175, Coolant . If
the coolant additive G12+ + is not available in
an emergency, you must not add any other ad­
ditive. In this case, use only water and restore
the correct mix ratio with the specified cool­
ant additive as soon as possible.
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 .
With a major loss of coolant, you should add
the coolant only when the engine has
cooled.
In this way you prevent engine damage .
Checking and filling 177
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 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
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire .
- Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
Q) Note
-Coolant pollutes the environment and
could cause an engine fire. Excess cool­
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 175 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.

Explosive gases can cause blindness or
other injury.
- Battery acid contains sulfuric acid. Sulfu­
ric acid can cause blindness and severe
burns.
- Always wear gloves and eye protection.
Do not tilt the battery because acid
could leak out of the ventilation open­
ings.
- If you get battery acid in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get medical attention.
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca­
ble.
- Before performing any work on the elec­ trical system, switch off the engine and ignition as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected. If you are just go­

When charging at low voltages (e.g . with a
trickle charger ), the battery cables do not
have to be disconnected first. Before charging
at
high voltages, i.e. "fast charging", you
must disconnect both cables. In either case,
follow the instructions from the manufacturer
of the charger .
Fastcharging a battery is
dangerous ¢ & in
Working on the battery on page 179 .
It re­
quires special charging equipment and the knowledge to go with it. We recommend hav ­
ing your battery fast charged only by a quali­
fied workshop.
A discharged battery can
freeze at tempera­
tures of only 32 °F (0 °C) . Allow a frozen bat ­
tery to thaw completely before attempting to
charge it¢ & . However, we recommend not
using a thawed battery again because the bat­
tery casing can be cracked due to ice forma ­
tion and can leak battery acid .
Do not open the battery caps when charging
the battery.
_& WARNING
-
Charging a battery can be dangerous.
- Never charge a frozen battery .
It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion , never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­ ment.
Checking and filling 181
- Battery acid that may spill during charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid .
@ Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc ., as well
as the battery charger .
(D Tips
-The vehicle battery must not be charged
with a standard small charger that plugs
into the cigarette lighter or outlet .
- Only charge the battery through the con­
nections in the luggage compartment.
Replacing the battery
The new battery mus t have the same specifi­
cations as the old one.
Your vehicle is equipped with an intelligent
energy management system for distributing
electricity¢
page 147 . The battery charges
better in vehicles with the energy manage ­
ment system than in vehicles without the sys­
tem . To ensure that the additional power is
available after replacing the battery , replacing
with the same type of battery from the same manufacturer (like the battery that was deliv­
ered with the vehicle) is recommended. An au­
thorized dealer must code the battery in the
energy management control module.
The new battery must have the same capacity,
voltage (12 volts), current and design and it
must be sealed with plugs. The battery must
conform to the standards TL 825 06 (from
April 2008) and VW 7 SO 73 (from April 2010).
Since the vehicle battery is difficu lt to reach,
we recommend having the battery replaced by
an authori zed Audi RB dealer or other quali-
fied workshop . ..,. •

182 Checking and filling
(D Note
- Your vehicle is equipped with a specia l
battery. Installing a different type of
battery can cause prob lems in the vehi­
cle electrical system. When replacing the
vehicle battery, always install one with
the same spec ificat ions as the original
battery .
- Make sure that the gas venting hose is
always connected to the o riginal open ing
on the battery side. Otherw ise gasses or
ba tte ry acid could leak out .
- Battery holder and term inals a lways
have to be secured cor rectly.
- Read and follow the warnings under
9 page 179, Working on the battery be­
fore performing any work on the batte ry.
@) 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 sulfur ic ac id and
lead and must always be disposed of prop­
erly in compliance with a ll environmenta l
reg ulations. D isposing of vehicle batteries
improperly is very dangerous to the envi­
ronment. Make sure that the removed bat­
tery ca nnot overbalance, otherwise sulfu­
r ic acid might escape!

Clean water should be used when filling up. If
possible, use soft water to prevent scaling on
the washer jets . Always add a glass cleaner
solution (with frost protection in the winter) .
(D Note
- Do not mix engine coolant antifreeze or
any other additives to fill up the wind­
shield washer reservoir.
- Do not use glass cleaners containing
pai nt so lvent; you risk damaging the

ways compare the tire size designation on the
tire pressure labe l on you r vehi cle w it h the
tires on your vehicle. Ma ke s ure that the ti re
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
load limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle . These load lim its are technically refer­
red to as the vehicle's G ross Vehicle We ight
Rati ng ("GVWR"). The G ross Ax le Weight Rat­
i ng ("GAWR") is the max imum load that can
be app lied at each o f the veh icle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance stic ker labe l located either
on the driver's side B-pillar. The tire pressure
labe l on your Audi lists the maximum com­
b ined weight of all of the occupants and lug­
gage or other cargo that the veh icle can carry.
