.... Avoid
driving at high speed
Avoid travelling at top speed. Fuel consumption,
exhaust emissions and noise Levels all increase
very rapidly at higher speeds. Driving at moder­
ate speeds will help to save fuel.
Do not let the engine idle for longer than
necessary
Engine idling periods are automatically reduced
on vehicles with start/stop system*. On vehicles
without start/stop system*, it is worthwhile
switching off the engine at Level crossings, for in­
stance, or at traffic lights with a Long red phase.
The fuel saved after only 30 -40 seconds is great­
er than the amount of fuel needed to restart the
engine.
The engine takes a very Long time to warm up
when it is running at idling speed. Mechanical
wear and pollutant emissions are also especially
high during this initial warm-up phase. It is
therefore best to drive off immediately after
starting the engine. Avoid running the engine at
high speed.
Regular ser vicing
Regular servicing can establish a basis for good
fuel economy before you start driving. A well­
serviced engine gives you the benefit of im­
proved fuel efficiency as well as maximum relia­
bility and an enhanced resale value.
A poorly maintained engine can consume up to
ten percent more fuel than necessary.
Check the oil level when filling the tank. Oil con­
su mption depends to a great extent on the en­
gine load and engine speed. It is quite normal
that the oil consumption of a new engine only
reaches its lowest level after a certain mileage.
This means that the oil consumption can only be
properly assessed after about 5,000 km. Depend­
ing on your personal driving style, oil consump­
tion can be up to 0.5 Ltr./1,000 km.
Avoid short trips
The engine and emission control system need to
reach their proper working temperature in order
to minimise fuel consumption and emissions . Driving
A cold engine uses disproportionately more fuel.
The engine only reaches its working temperature
after about four kilometres, when fuel consump­
tion will return to a normal level.
Check tyre pressures
Always make sure the tyres are inflated to the
correct tyre pressures to save fuel. If the tyre
pressures are just 0.5 bar too Low, this can in­
crease the fuel consumption by as much as 5 %.
Due to the greater rolling resistance, under-infla­
tion also increases tyre wear and impairs han­
dling.
The tyre pressures should always be checked
when the tyres are cold.
Do not use winter tyres all through the year; they
will increase fuel consumption by up to 10 %.
Avoid carrying unnecessary loads
Every kilo of extra weight will increase the fuel
consumption, so it is worth checking the Luggage
compartment occasionally to make sure that no
unnecessary Loads are being transported.
Save electrical energy
The engine drives the alternator to generate elec­
tricity. This means that fuel consumption rises
when more power is required for electrical equip­
ment. Switch off electrical equipment when it is
not needed. Electrical equipment which uses a
Lot of electricity includes the blower (at a high
setting), the rear window heating and the seat
heating*.

sure that children do not lean out of the
child seat towards the door trim. If the side air­
bag were to inflate in an accident, it could strike
the child on the head and cause serious injury.
A WARNING
- To avoid injury, the child's head must always
be well away from the opening for the side
airbag.
- Do not leave or place any objects in the area
of inflation for the side airbag -risk of in­
jury!
Child seat categories
Only use child restraint systems that are official­
ly approved and suitable for the child.

Fig. 174 Child seat categories
Child restraint systems are covered by the Euro­
pean standard ECE-R 44. An orange label is usu­
ally attached to child seats which have been tes­
ted in accordance with this standard. Informa­
tion on weight categories, ISOFIX size class and
the approval category of the child seat can be
found on this label.
Child seats are divided into five weight catego­
ries:
Child seats: categories O and O+
Rearward-facing carry cots are most appropriate
for these categories (up to 13 kg). Our recom­
mendation: Audi carry cot with optional ISOFIX
base.
Child seats: category 1
In this category (9 to 18 kg), rearward or for­
ward-facing child seats with an integrated seat Safe
driving
belt system are most appropriate. Rearward-fac­
ing child seats should be used for as long as safe­
ly possible. Our recommendation: Audi child seat
with ISOFIX base.
Child seats: categories 2 and 3
Child seats with backrests used in conjunction
with seat belts are most appropriate for these
categories (15 to 36 kg). Our recommendation:
Audi child seat "youngster plus".
A WARNING
- Categories 0, O+ and 1 (rearward-facing):
Never install a rearward-facing child seat on
the front passenger's seat unless the front
passenger's airbag has been deactivated -
this can result in potentially fatal injuries to
the child. If you have no alternative but to
let a child travel on the front passenger's
seat, the front passenger's airbag must be
deactivated* beforehand c:> page 211.
- Categories 1 (forward-facing), 2 and 3: The
back of the child seat should be flush with
the backrest of the vehicle seat.
- Categories 2 and 3: The shoulder section of
the belt must be fitted across the centre of
the child's collar bone close to the torso. It
must never run against or across the neck.
The lap belt must be worn tightly across the
hips, and not over the stomach or abdomen.
Pull the belt tight if necessary to take up
any slack.
1 Note
We recommend child seats from the range of

& WARNING
- Use only tyre/rim combinations and match­
ing wheel bolts approved by Audi. Otherwise
damage to the vehicle and an accident could
result.
- For technical reasons, it is not possible to
use wheels from other vehicles. In certain
cases, it is not even possible to use wheels
from another vehicle of the same model.
- It is very important to ensure that the tyres
you have chosen have adequate clearance.
When selecting replacement tyres, do not
rely entirely on the nominal tyre size marked
on the tyre; with some makes of tyre the ef­
fective tyre size can differ significantly from
the nominal dimensions, even though the
tyres have the same size designation. Inade­
quate tyre clearance can result in damage to
the tyres or the vehicle, causing a serious
safety risk.
- Avoid running the car on tyres that are more
than 6 years old. If you have no alternative,
you should drive slowly and with extra care
at all times.
- The use of run-flat tyres on your vehicle is
NOT authorised! Unauthorised use can cause
an accident or damage your vehicle.
- If wheel trims are fitted after the car is pur­
chased, ensure that there is an adequate
flow of air for cooling the brakes -risk of ac­
cident!
Tyre wear / damage
Fig. 219 Tyre tread: Tread wear indicators

Please observe the applicable regulations in the country in
which you are travelling.
232 Tyre
wear
Inspect the tyres regularly for damage.
- The wear on under or over-inflated tyres is sig­
nificantly higher.
- Fast cornering, heavy acceleration and hard
braking all increase tyre wear.
- If you notice excessive tyre wear, have the
wheel alignment checked by a qualified work­
shop.
- Have your tyres rebalanced if steering wheel vi­
brations indicate an imbalance. Otherwise, the
tyres and other parts of the vehicle may wear
faster.
Tread wear indicators
The original tyres on your vehicle have 1.6 mm
high tread wear indicators ¢ Fig. 219 running
across the tread at regular intervals. The letters
"TWI" or triangles on the sidewall indicate the
positions of the tread wear indicators.
The minimum tread depth 1
) is reached at the lat­
est when the tread is worn down to the tread
wear indicators. Replace the tyres with new ones
¢ ,&..
Changing wheels round
Wheels should be changed round regularly to en­
sure that the wear is equal on all tyres. Fit the
wheels from the rear axle on the front axle and
vice-versa. All the tyres will then last for about
the same time.
On tyres with a directional tread pattern, note
the direction of rotation indicated on the sidewall
¢page 247.
Concealed damage
Damage to tyres and rims is often not readily visi­
ble. If you notice unusual vibrations or the car
pulling to one side, this may indicate that one of
the tyres is damaged. Reduce your speed imme­
diately. Inspect the tyres for damage. If no exter­
nal damage is visible, drive slowly and carefully
to the nearest qualified workshop and have the
car inspected.

play. If only one tyre is affected, the display will
indicate its position.
Each time you change a tyre, change the wheels
round or change the tyre pressures on your vehi­
cle (e.g. when switching from partial load to full
load and vice-versa), you must store the new tyre
pressures on the infotainment system
¢ page 235. Monitoring of the tyre pressures is
based on the tyre pressures you have stored. The
inflation pressures recommended for your vehicle
are given on the tyre pressure sticker
¢ page 233, Fig. 220.
The rolling circumference and vibration can
change and cause a tyre pressure warning if:
- The inflation pressure in one or more tyres is
too low.
- The tyre has suffered structural damage.
- The wheels were changed or the tyre pressures
were changed and the new tyre pressures were
not stored ¢ page 235.
- You are driving with the temporary spare
wheel*.

stop and check the tyres and the tyre pres­
sures.
- It is the driver's responsibility to ensure that
the tyre pressures are correct. For this rea­
son you must check the tyre pressures regu­
larly.
- Under certain conditions (e.g. driving at
high speeds, on ice and snow or on poor
road surfaces) the tyre pressure loss indica­
tor may not appear immediately.
- Run-flat tyres* may only be used on vehicles
which were originally equipped with this
type of tyre.
- If a malfunction occurs in the ESC system,
the tyre pressure loss indicator may also be
out of action.
- When driving with snow chains, a system
malfunction can occur.
- The tyre pressure loss indicator on your Audi
is specially matched to tyres with the mark­
ing "AO" or "RO" ¢ page 231. We recom­
mend that you use these tyres.
Storing tyre pressure settings
Applies to vehicles: with tyre pressure loss indicator
When you change a tyre or the tyre pressure on
your vehicle, you must confirm the change on the
infotainment system.
� Before storing the new tyre pressures, check
that the current pressures on all four wheels
correspond to the specified values and adapt
the pressures to the current load ¢ page 232.
� Switch on the ignition.
� Select the
following on the infotainment sys­
tem: I MENU I button >Car> left control button
