Never spill fluids on a hot engine. These flu­
ids can cause a fire (e.g. radiator anti­
freeze).
- Take care not to cause short circuits in the
electrical system, especially when working
on the battery.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off-risk of injury!
- Do not unscrew the cap on the expansion
tank when the engine is hot. The cooling
system is under pressure.
- Protect face, hands and arms by covering
the cap with a large, thick rag to protect
against escaping coolant and steam.
- Never remove the engine cover panel -risk
of burns!
- If any tests have to be performed with the
engine running, there is an extra safety risk
from the rotating parts, such as the drive
belts, alternator and radiator fan, etc., and
from the high-voltage ignition system.
- Vehicles with automatic gearbox: Never
open the throttle inadvertently (for instance
by hand from the engine compartment) if a
gear is engaged while the vehicle is station­
ary with the engine running. The vehicle
could otherwise start moving immediately
and possibly cause an accident.
- Observe the following additional warnings if
work on the fuel system or the electrical
system is necessary:
- Always disconnect the battery.
- Do not smoke.
- Never work near naked flames.
- Always keep an approved fire extinguisher
immediately available.
CD CAUTION
When topping up fluids make sure the correct
fluid is put into the correct filler opening. This
can otherwise cause serious malfunctions or
engine damage. Checking

Battery General notes
ALL work on batteries requires specialist knowl­
edge.
The battery is virtually maintenance-free. It is
checked as part of the Inspection Service.
When an airbag is triggered, the battery will, un­
der certain circumstances, be disconnected from
the on-board power supply for safety reasons
¢ .&.. in General notes on airbag system on
page 209.
Disconnecting the battery
The battery should always be Left connected. If
the battery is disconnected, some of the vehicle's
functions will become inoperative (e.g. electric
windows). These functions will require resetting
after the battery is reconnected. For this reason,
the battery should only be disconnected from the
vehicle's electrical system when absolutely nec­
essary.
If the vehi cle is not used for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power management
will gradually shut off the on-board systems one
by one, or reduce the amount of current they are
using. This Limits the amount of power consumed
and helps to ensure reliable starting even after a
Long period ¢ page 106. Certain convenience fea­
tures, such as interior Lighting or electric seat ad­
justment, may not be available. These functions
will be restored when you switch on the ignition
and start the engine. Even though some systems
are deactivated automatically, certain electrical
equipment continues to draw current even when
the ignition is off. If the vehicle is Left standing
for several months, this can result in total bat-
tery discharge. If the battery is allowed to dis­
charge completely, an internal chemical reaction

the battery. To avoid this, the battery
should be recharged at least once a month
¢ page 228. Do not disconnect the battery; oth­
erwise the anti-theft alarm system* will be out of
operation.
Winter conditions The battery is drained more in cold weather,
which means that the starting power is reduced.
For this reason, have the battery checked and
charged if necessary before the start of winter.
A WARNING
-
-All work on batteries requires specialist
knowledge. For queries regarding the vehi­
cle battery please seek the assistance of a
qualified workshop -risk of chemical
burns / risk of explosion!
- The battery must not be opened. Do not at­
tempt to make any changes to the electro­
lyte level of the battery. Otherwise, there is
a risk that a mixture of oxygen and hydrog en
gas can accumulate and cause an explosion.

battery, we recommend that the replacement
battery used is of the same make and type as the
original-equipment battery. After changing the
battery, the power management system must be
initialised by a qualified workshop to ensure that
the replacement battery is charged to an opti­
mum level.
A replacement battery must have the same ca­
pacity, voltage (12 V) and current rating. It must
also have the same dimensions as the original,
factory-fitted battery and have sealed caps. The
battery must comply with the standards
TL 825 06 (dated April 2008 or later) and
VW 7 50 73 (April 2010 or later).
Since the battery is difficult to access, we recom­
mend having it replaced by an Audi dealer or
qualified workshop.
CD CAUTION
- Your vehicle is equipped with a special deep
cycle battery (e.g. AGM type). The on-board
electronic systems may develop problems if
you fit a different type of battery. For this
reason, if you need to replace the vehicle
battery, make sure that the specifications of
the new battery match the original exactly.
- Make sure that the vent hose is always at­
tached to the original opening on the side of
the battery. Gases or battery acid can other­
wise escape and possibly cause damage.
- The battery holder and clamps must always
be correctly secured.
- Before starting any work on the battery, al­
ways observe the warnings listed under
¢ page 227, Important safety warnings for
handling a car battery.
@ For the sake of the environment
"S Batteries contain toxic substances including
sulphuric acid and lead. They must be dis­
posed of appropriately and must not be put
together with ordinary household waste.
