check engine light AUDI RS5 CABRIOLET 2013 Owner's Manual

-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
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery , switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables - this could start a fire!
Checking and filling 219
- Never charge a frozen or a thawed-out
battery . It could explode! If a battery has
frozen, then it must be replaced. A dis­
charged battery can freeze over at 32°F
(ooc).
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion! Al ­
ways replace a damaged battery .
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems . Wash hands after han­
dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is switched on or when
the engine is running, otherwise, you will
damage electronic components in the
electrical system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
Battery charging
Start ing the engine requires a well charged
battery.

Battery replacement
The new battery must have th e sam e specifi­
cations and dim ensions as the original equip­
ment battery.
Intell igent energy management in your vehi­
cle is respons ible for d istr ibuting the e lectr i­
cal energy throughout your vehicle
c::>
pag e 182. The intel ligent e nergy ma nage­

install batteries of the same type and man u­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations a re listed on the battery hous ing. Your
author ized Audi d ealer must code the battery
in the energy management system to enable
you to u se the ene rgy man agement func tions
correctly a fter rep lac ing the b att ery.
If it is not poss ible to use a battery of this
type, the new battery must have the same ca­
paci ty, voltage ( 12-volts), ampe rage, con­
s truc tion and pl ug sea ling.
W hen insta lli ng the battery, make sure the ig­
ni tion and all e lectr ical c ons umers a re turned
off.

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who have the necessary tools and equipment to
perform these operations.
Starting by pushing or
towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing.
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
gine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to carry the starter current
safely. Refer to the manufacturer's specifica­
tions.
Use only jumper cables with
insulated termi­
nal clamps which are distinctly marked:
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black .
A WARNING
Batteries contain electricity, acid, and gas.
Any of these can cause very serious or fatal
injury. Follow the instructions below for
safe handling of your vehicle's battery.
- Always shield your eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 255
-A discharged battery can freeze at tem­
peratures just below 32 °F (0 °C). Before
connecting a jumper cable, you must
thaw the frozen battery completely, oth­
erwise it could explode.
- Do not allow battery acid to contact eyes
or skin . Flush any contacted area with
water immediately .
- Improper use of a booster battery to
start a vehicle may cause an explosion.
- Vehicle batteries generate explosive gas­
es. Keep sparks, flame and lighted ciga­
rettes away from batteries.
- Do not try to jump start any vehicle with
a low acid level in the battery.
- The voltage of the booster battery must
also have a 12-Volt rating. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged bat­
tery. Use of batteries of different voltage
or substantially different "Ah" rating
may cause an explosion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped in the ice may cause an explosion.
- Never charge or use a battery that has
been frozen. The battery case may have
be weakened.
- Use of batteries of different voltage or
substantially different capacity (Ah) rat­
ing may cause an explosion and injury.
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
page 200, Engine com­
partment.
(D Note
- Applying a higher voltage booster bat­
tery will cause expensive damage to sen­
sitive electronic components, such as
control units, relays, radio, etc .
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
positive(+) terminals are connected. ..,. •
