Child safety


ZA\ WARNING
Always take special precautions if you must
install a forward or rearward-facing child re-
straint on the front passenger's seat in excep-
tional situations:
— Whenever a forward or rearward-facing
child restraint is installed on the front pas-
senger seat, the PASSENGER AIR BAG OFF
#; light must come on and stay on whenever
the ignition is switched on.
— If the PASSENGER AIR BAG OFF %; light
does not come on and stay on, perform the
checks described > page 198, Monitoring
the Advanced Airbag System.
— If the PASSENGER AIR BAG OFF %; light
does not come on and stay on whenever the
ignition is switched on the inflating airbag
will hit the child safety seat or infant carrier
with great force and will smash the child
safety seat and child against the backrest,
center armrest, door or roof. Have the air-
bag system inspected immediately by your
Audi dealer.
— Improper installation of child restraints can
reduce their effectiveness or even prevent
them from providing any protection.
— An improperly installed child restraint can
interfere with the airbag as it deploys and
seriously
injure or even kill the child.
— Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.
— After checking to make sure that the child
restraint is properly installed, make certain
that the child restraint is correctly recog-
nized by the capacitive passenger detection
system in the front passenger seat and that
the PASSENGER AIR BAG OFF %; light sig-
nals the correct front passenger frontal air-
bag status.


ZA\ WARNING
Forward-facing child restraints:
— Always make sure the forward-facing seat
has been designed and certified by its manu-
facturer for use on a front seat with a pas-
senger front and side airbag.

— Never put the forward-facing child restraint
up, against or very near the instrument pan-
el
— Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air-
bag as possible before installing the for-
ward-facing child restraint. The backrest
must be adjusted to an upright position.
— Make sure that the PASSENGER AIR BAG
OFF 3%; light comes on and stays on all the
time whenever the ignition is switched on.

ZA WARNING
Rearward-facing child restraints:
—A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates - even with an Ad-
vanced Airbag System.
— The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest, door
or roof.
— Always be especially careful if you must in-
stall a rearward facing child safety seat on
the front passenger seat in exceptional cir-
cumstances.
— Make sure that the PASSENGER AIR BAG
OFF %; light comes on and stays on all the
time whenever the ignition is switched on.
— If the PASSENGER AIR BAG OFF #; light
does not come on and stay on, have the air-
bag system inspected by your Audi dealer.

> Depress the spring catch on the hook and re-
lease it from the anchorage.
©) Note
If you leave the child restraint with the tether
strap firmly installed for several days, this
could leave a mark on the upholstery on the
seat cushion and backrest in the area where
the tether strap was installed. The upholstery
would also be permanently stretched around
the tether strap. This applies especially to
leather seats.
Using tether straps on rearward-facing
Riera)
Applies to: vehicles with Tether anchors and tether straps
Currently, few rear-facing child restraint systems
come with a tether. Please read and heed the
child restraint system manufacturer's instruc-
tions carefully to determine how to properly in-
stall the tether.

Z\ WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be

seriously injured and can be killed if the front
airbag inflates - even with an Advanced Airbag
System.
— The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child
against the backrest, center armrest or
door.
— Never install a rearward facing child safety
seat on the front passenger seat unless the
PASSENGER AIR BAG OFF 3; light comes
on and stays on. If the PASSENGER AIR
BAG OFF ¥; light does not come on and stay

Checking and Filling

— Do not use any gasoline mixture whose
composition cannot be identified.
— Audi does not assume any responsibility for
damage to the fuel system or for perform-
ance problems caused by using gasoline
mixtures different from those specified.
This type of damage also does not fall under
the New Vehicle Limited Warranty or under
the emissions control system warranty.
— If you notice a higher fuel consumption or
poor handling or performance problems due
to such gasoline mixtures, we recommend
fueling with unblended gasoline.
Gasoline additives
An important issue for many automobile manu-
facturers is combustion residue in the engine
that results from the use of certain fuels.
Although types of gasoline differ depending on
the manufacturer, there are similarities. Certain
substances in the gasoline may cause deposits in
the engine. Additives in the gasoline that should
keep the engine and fuel system clean do not all
function equally.
Audi recommends using TOP TIER Detergent Gas-
oline. For additional information on TOP TIER De-
tergent Gasoline, visit www.toptiergas.com.
If you use incorrect fuels over a long period of
time, the maximum engine performance may be
impaired by combustion residue.
@) Note
— Damage or malfunctions caused by the use
of incorrect types of gasoline are not cov-
ered by the New Vehicle Limited Warranty.
— Only gasoline additives that have been ap-
proved by Audi may be used.

off the first time, the fuel tank is full. Do not
continue fueling, or else the expansion space in
the tank will be filled with fuel.
> After the fuel pump has switched off, wait five
seconds before removing the nozzle to allow
the rest of the fuel to finish dripping into the
fuel tank.

Coolant Freeze protec-
additive tion
Warm min. 40% min. -13 °F
regions max. 45% (-25 °C)
Cold min. 50% max. -40 °F
regions max. 55% (-40 °C)

@) Note
— Before the start of winter, have an author-
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
— If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en-
gine. If this happens, only use water and re-
store the correct mixture ratio with the
specified coolant additive as soon as possi-
ble.
— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.
@ Tips
In certain weather conditions, water can
evaporate on the radiator and exit the side
vents as steam after stopping the engine.
Adding coolant

Fig. 183 Engine compartment: markings on the coolant
expansion tank
Observe the safety precautions > page 229, Gen-
eral information.
Checking the engine coolant level
>» Park the vehicle on a level surface.
>» Switch the ignition off.
> Allow the engine to cool.
> Place a large, thick cloth over the coolant ex-
pansion tank cap and unscrew the cap counter-
clockwise > A\.
> Read the coolant level using the coolant level
float. The coolant level float may only stick out
over the edge of the coolant expansion tank a
maximum of 0.39 in (1 cm) when the engine is
cool.
Adding coolant
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Add coolant in the correct mixture ratio
=> page 236 until the dipstick is no more than
0.39 in (1 cm) above the edge of the coolant
expansion tank.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

ZA\ WARNING
— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-
low it to cool before working in the engine
compartment. Always follow the informa-
tion found in > page 229, General informa-
tion.
— Never open the engine compartment lid if
you can see or hear steam or coolant escap-
ing from the engine compartment. This in-
creases the risk of burns. The cooling system
is under pressure. When you no longer see
or hear steam or coolant escaping, you may
open the engine compartment with caution. |>

@) Note
— The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions and the climate. A concentration
that is too high can lead to vehicle damage.
— 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.
The service interval display works in two stages:
— Inspection or oil change reminder: after a cer-
tain distance driven, a message appears in the
Infotainment system display each time the ig-
nition is switched on or off. The remaining dis-
tance or time is displayed briefly.
— Inspection or oil change due: if your vehicle
has reached an inspection or oil change interval
or both intervals at the same time, the mes-
sage Inspection due! or Oil change due! or Oil
change and inspection due! appears briefly af-
ter switching the ignition on or off.
Checking service intervals
You can check the remaining distance or time un-
til the next oil change or next inspection. Select
in the Infotainment system: the [MENU] button >
Vehicle > left control button > Service & checks >
Service intervals.


Resetting the indicator
An authorized Audi dealer or authorized Audi
Service Facility will reset the service interval dis-
play after performing service.
If you have changed the oil yourself, you must re-
set the oil change interval.
To reset the display, select in the Infotainment
system: the [MENU] button > Vehicle > left con-
trol button > Service & checks > Service intervals
> Reset oil change interval.



CG) Note
— Only reset the oil change indicator if the oil

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au-
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace-
ment parts.
>New tires do not yet have the
optimal gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
> Only use tires with the same de-
sign and as close to the same
tread pattern as possible on all
four wheels.
>Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
> Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
differently even if they are the
same size 9 A.
>If you would like to equip your
vehicle with a tire and rim com-
bination that is different from
what was installed at the facto-

Wheels

Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 254.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 245, fig. 191.
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
260
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band C. Those grades represent the tire's
ability to stop on wet pavement as measured un-
der controlled conditions on specified govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
oA.
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate-
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure > A\.
The grade C corresponds to a level of perform-
ance which all passenger car tires must meet un-
der the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.

ZA\ WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning or peak traction charac-
teristics. >
