A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and re lated acces­
sories contain lead and lead compounds,
chemica ls known to the State of California
to cause cancer and reproductive problems.
Wash hands after handling .
@ Note
-If the vehicle will be parked for long periods
of time, protect it against the cold so that it
will not be destroyed by "freezing"
<=>page 323.
-There are electrical components under the
cargo floor behind a trim pane l that warm
up during operation. To reduce the risk of
the components overheat ing, do not store
objects such as blankets under the cargo
floor . If they overheat, the components wi ll
switc h off temporarily. This will be ind icat ed
by a message in the instrument cluster, un­

@ For the sake of the environment
i Batteries contain polluting substances such
as sulfur ic acid and lead. Contact an author­
i zed Audi dealer or authorized Audi Service
Fac ility for more informat ion.
Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually sca led
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of
time<=> page 145 . Some convenience
funct ions, such as interior lighting or power seat
adjustment, may not be available under certain
circumstances . These convenience functions will
be available again once you switch t he ignition on
and start the engine .
Even when electrical equipment is switched off,
the equipm ent can still drain the vehicle battery
if the vehicl e is not driven for long periods of
time. Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery.
The vehicle battery must be charged every month
to reduce the risk of this happening
<=> page 323.
Contact an authorized Aud i dealer or authorized
Audi Service Fac il ity for more information.
Winter operation
Cold weather places higher demands on the vehi­
cle battery. This results in reduced starting abili­
ty. Have the vehicle battery checked by an au­
thorized Audi dealer or authorized Audi Service
Fac il ity before the cold time of year .

Checking and Filling
-Never add radiator anti-freeze or other addi­
tives to the washer fluid.
-Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint .
Service interval display
The service interval display detects when your ve­
hicle is due for service.
Checking service intervals
You can check the remaining distance or time un­
til the next oil c hange or next inspection in the
Infotainment system .
.,. Select in the Infot ainment system: the I MENU I
button > Vehicle > left contro l button > Service
& checks > Service intervals.
Resetting the indicator
An author ized Audi dealer or authorized Audi
Service Facility will reset the service interval dis­
p la y after performing serv ice.
If you have changed the oil yourself, you must re­
set the oil c hange interva l.
.,. Select in the Infotainment system: the lMENUI
button
> Vehicle > left control button > Service
& checks > Service intervals > Reset oil change
interval.
If an oil change or inspection is due, you can ac­
cess it in the Infotainment system . The display
works in two stages:
-Service reminder: after a certain distance is
driven, a message appears in the instrument
cluster display every time the ign ition is switch­
ed on. The remaining distance and t ime is dis­
played br iefly.
-Service due : if your vehicle has reached a serv­
ice interval, a message appears briefly after
switching the ignition on.
0 Note
-Only reset the oil change indicator if the oil
was c hanged.
-Following the service inter vals is critical to
maintain ing the service life and value of
324
your vehicle, especially the engine . Even if
the mileage on the ve hicle is low, do not ex ­
ceed t he time for the next service .

Emergency situations
General
This chapter is intended for trained emergency
crews and working personnel who have the nec­
essary tools and equipment to perform these
operations.
Starting by pushing or
towing
~ 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 con­
necting it to the battery of another vehicle.
If the engine should fail to start because of a dis­
charged or weak battery, the battery can be con­
nected to the battery of
another vehicle, using a
pair of jumper cables to start the engine.
Jumper cables
Use only jumper cables of sufficiently large cross
section
to carry the starter current safely. Refer
to the manufacturer's specifications.
Use only jumper cables with
insulated terminal
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 in­
jury. Follow the instructions below for safe
handling of your vehicle's battery.
-Always shield your eyes and avoid leaning
over the battery whenever possible.
- A dead battery can freeze at temperatures
around 32 °F (0 °C). If the vehicle battery is
frozen, you must thaw it before connecting
the jump start cables. If you do not, this in-
Emergency situations
creases the risk of an explosion and chemi­
cal burns. After jump starting the vehicle,
drive to an authorized Audi dealer or author­
ized Audi Service Facility immediately to
have the vehicle battery checked.
- 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 gases.
Keep sparks, flame and lighted cigarettes
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 battery. Use of
batteries of different voltage or substantial­
ly different "Ah" rating may cause an explo­
sion and personal injury.
- Never charge a frozen battery. Gas trapped
in the ice may cause an explosion.
- Never charge or use a battery that has been
frozen. The battery case may have be weak­
ened.
- Use of batteries of different voltage or sub­
stantially different capacity (Ah) rating may
cause an explosion and injury. The capacity
(Ah) of the booster battery should not be
lower than that of the discharged battery.

Consum er Info rmation
today's automobi les, have steadi ly red uced the
scope of maintenance and repairs which can be
carried out by veh icle owners.
Al so , sa fet y and
en vironmental
concerns place very strict limits
on the nature of repairs and adjustments to en­
g ine and transmission parts w hich an owner can
perform .
Maintenance, adjustments and repairs usually re­
qu ire special tools, testing devices and other
equ ipment available to specially trained work ­
shop personnel in order to assure proper per­
forma nce, re liab ility and safety of the ve hicle and
its many systems .
Improper maintenance, adjustments and repairs
can impair the operation and reliab il ity of your
ve hicle and eve n void your vehicle warra nty .
Therefo re, proof of se rvicing in accordance w ith
the m aintenance schedule may be a condition fo r
up hold ing a possible wa rranty claim made wi thin
the warranty pe riod.
Above all, ope rational safety can be adversely af­
fected, c re ating unnecessa ry risks fo r you and
your passengers.
I f in doubt about any servicing, have it done by
your author ized Audi dealer or any other prope rly
eq uipped and qualified workshop . We strongly
urge yo u to g ive your author ized Audi dealer the
opportunity to perform a ll scheduled mainte ­
nance and necessary repairs. Your dealer has the
