WARNING
You should switch on the off-road mode or
switch off the ESC/traction control system
(ASR) only if your driving ability and the traf­
fic conditions allow you to do so safely -
dan­

ger of skidding!
- The stabilising function is restricted when
off-road mode is switched on. The driven
wheels may start to
spin,
causing the
vehi­

cle to lose grip, in particular on slippery or
wet roads.
- When the ESC/traction control system
(ASR) is switched off, the vehicle will not be

stabilised.

Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly re­
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear
The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicLe is operated. Negative factors

are,
for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises
Brake noise may develop in certain situations, de­
pending on the speed, braking force and ambient
conditions (such as temperature and relative hu­
midity).
Effect of moisture and salt
In certain conditions, such as in heavy
rain,
early
morning dew, or after washing the car or driving
through water, the full braking effect can be de­
layed by moisture (or in winter by ice) on the
discs and brake pads. The brakes should be
< "dried" by pressing the pedal to restore full brak-

R
ing effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet
con­

ditions.
The effectiveness of the brakes can also be
tem­

porarily reduced if the car is driven for some dis­
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be
removed with a few cautious brake applications.
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corrosion to form on the discs
if the car is used infrequently, or if
you
only drive
low mileages without using the brakes very

much.

If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed
•=> A-

Faults in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to the
nearest qualified workshop and have the fault

rectified.
On the way to the dealer, be prepared
to use more pressure on the brake pedal and al­
low for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid level
is monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal. It only works when the engine
is running. •

the standard tyres. Nevertheless, we still recom­
mend that winter tyres or all-season tyres should
be fitted on all four wheels when winter road
conditions are expected, mainly because this will
give a better braking response.
Snow chains
On roads where snow chains are mandatory, this
also applies to cars with four-wheel drive

Opcrge
309, Snow chains.
Replacing tyres
On vehicles with four-wheel drive, all four tyres
must have the same rolling circumference. Also
avoid using tyres with varying tread depths

tapage
305,
New wheels or tyres.
Off-roader?
Some models do not have enough ground clear­
ance to be used on rough tracks and uneven ter­

rain,
so it is best to avoid off-road driving.
A WARNING
- Even with four-wheel drive, you should al­
ways adjust your speed to suit the condi­

tions.
Do not let the extra safety provided
tempt you into taking any risks when driving
- this can cause accidents.
- The braking ability of your car is limited by
the grip of the tyres. In this respect, your
car is no different from a car without four-
wheel drive. So do not be tempted to drive
too fast on icy or slippery roads just because
the car still has good acceleration in these
conditions - risk of accident!
- On wet roads bear in mind that the front
wheels may start to "aquaplane" and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as with a front-wheel drive car. So do
not drive too fast in the wet: adjust your
speed to suit the conditions (accident risk).

Power management
This system helps to ensure reliable
starting

The
power management controls the distribu­
tion of electrical energy and thus helps to ensure
that there is always enough power available to
start the engine.
If
a
vehicle with a conventional electrical system
is left parked for
a
long time, the vehicle battery
will gradually lose its charge because certain
electrical equipment (such as the immobiliser)
continues to draw current even when the ignition
is off. In some cases there may not be enough
power available to start the engine.
Your vehicLe is equipped with an intelligent pow­
er management system to control the distribu­
tion of electrical energy. This significantly im­
proves reliability when starting the engine, and
also prolongs the life of the vehicle battery.
The main functions incorporated in the power
management system are battery diagnosis, re­
sidual current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the vehicle battery. Sensors
detect the battery voltage, battery current and
battery temperature. This enables the system to
calculate the current power level and charge
con­

dition of the vehicle battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It
con­

trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power Level of the vehicle bat­
tery, the individual electrical components are
switched off one after the other to prevent the
vehicle battery from losing too much charge and
to ensure that the engine can be started reliably. •
149

Intelligent technology
Dynamic power management
While the vehicle is moving, this function distrib­
utes the available power to the various electrical
components and systems according to their re­
quirements. It ensures that on-board systems do
not consume more electrical power than is being

generated,
and thus maintains the maximum
possible vehicle battery power level.
® Note
- The power management system is not able
to overcome the given physical limits.
Please remember that the power and life of
the vehicle battery are limited.
- If the indicator lamp
|3 ^page
31 appears,
the starting ability may be impaired.
Starting ability has first priority.
Short trips, city traffic and low temperatures all
place a heavy load on the vehicLe battery. In
these conditions a large amount of power is
con­

sumed,
but only
a
small amount is supplied. The
situation is also critical if electrical equipment is
in use when the engine is not running. In this
case power is consumed when none is being
gen­

erated.

In these situations you will be aware that the
power management system is intervening to
con­

trol the distribution of electrical power.
When the vehicle is parked 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. Certain convenience features, such
as remote controL unlocking, may not be availa­

ble.
These functions will be restored when you
switch on the ignition and start the engine.
150
With the engine switched off
If
you
listen to the radio or use the other info­
tainment functions when the engine is not
run­

ning,
this will discharge the vehicle battery.
The infotainment display will show a warning
message before the battery power drops to a Lev­
el where the starting ability is impaired. This
message warns you that the system you are using
will soon be switched off automatically. You
should therefore start the engine if
you
wish to
continue using the system.
When the engine is running
Although the alternator generates electrical
power, the vehicle battery can still become dis­
charged while the vehicle is being driven. This can
occur when a lot of power is being consumed but
only
a
small amount supplied, especially if the
vehicle battery is not fully charged initially.
To restore the necessary energy balance, the sys­
tem
will
then temporarily shut off the electrical
components that are using a lot of power, or re­
duce the current they are consuming. Heating
systems in particular use a Large amount of elec­
trical power. If
you
notice, for instance, that the
seat heating* or the rear window heater is not

working,
they may have been temporarily switch­
ed off or regulated to a lower heat output. These
systems will be available again as soon as
suffi­

cient electrical power is available.
You may also notice that the engine runs at a
slightly faster idling speed. This is quite normal,
and no cause for concern. The increased idling
speed allows the alternator to meet the greater
power requirement and charge the vehicLe bat­
tery at the same time.
Information saved in the
control units
The vehicle is fitted in the factory with electronic
control units that, among other things, control
the engine and the gearbox. The controL units al­
so monitor the exhaust system and the airbags.
The control units continually analyse data rele­
vant to the vehicLe while you are driving. In the •

Fuel
Petrol grade
Applies to: vehicles with petrol engine

The
correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic converter
and must only be run on unleaded petrol. Petrol
must be sulphur-free and must comply with the
EN 228 standard. You can fuel your vehicle with
fuels containing a maximum of 10%
ethanol

(E10). The petrol grades have different octane
ratings (RON).
The following headings relate to the sticker on
the inside of your vehicle's tank flap:
Unleaded fuel only RON/ROZ
95
Super,
Premium or
min.
RON/ROZ 91 Normal
The use of premium petrol (95 RON) is recom­

mended.
If
that
type of fuel is not available,
reg­

ular petrol (RON 91) can be used with a slight
loss of power.
Unleaded fuel only, min. RON/ROZ
95

Super, Premium
Premium petrol (at least 95 RON) must be used.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

Unleaded fuel only RON/ROZ 98 Super Plus
or min. RON/ROZ 95 Super, Premium
The use of Super Plus petrol (98 RON) is recom­

mended.
If
that
type of fuel is not available, pre­
mium petrol (RON 95) can be used with a slight
loss of power.
If premium petrol is not available, the engine can
be run on regular petrol with 91 RON as an
emer­

gency measure. In this case only use moderate
engine speeds and a light throttle. Fill up with
premium or Super Plus petrol as soon as possi­

ble.

© CAUTION
- Do
NOT fuel
your vehicle with
high-ethanol

fuel blends (e.g. E50 or E85). This will dam­
age the fuel system.
- just one tank of leaded fuel or fuel with
metallic additives will permanently impair
the efficiency of the catalytic converter.
- You should use only petrol additives which
have been approved by Audi. Additives with
so-called octane boosters or antiknock
addi­

tives can contain metallic additives that
cause significant damage to the engine and
the catalytic converter. Do not use such ad­
ditives.
- Metal-based fuels, which can be identified
from the marking on the fuel dispenser,
must not be used. LRP fuel (lead replace­
ment petrol) also contains high concentra­
tions of metallic additive. Risk of engine
damage!
- High engine speed and full throttle can
damage the engine when using petrol with
an octane rating lower than the correct
grade for the engine.
- You can use higher octane fuel than your en­
gine requires.
- In countries where sulphur-free fuel is not
available, you may use low-sulphur fuel in­

stead.

Diesel fuel
Applies to: vehicles with diesel engine
Please note the information on the inside of the
fuel tank flap.
The use of sulphur-free diesel complying with
the EN 590 standard is recommended.
Diesel can thicken at very low temperatures,
which can result in problems starting the engine
or prevent the engine from running smoothly.
For this reason, filling stations in some countries
offer winter-grade diesel fuel during the cold

Checking and topping up fluids
months so that you can continue to operate your
vehicle reliably. Ask at your filling station wheth­
er the diesel fuel available there is suitable for
the current conditions and for the temperatures
which could potentially occur.
© CAUTION
- Never use FAME fuels (biodiesel), petrol,
heating oil, thinners or any other fuels or
additives, as these could cause serious dam­
age to the fuel system and the engine.
- Never start the engine if
you
fill up with the
wrong type of
fuel,
as this could damage
the fuel system and the engine. Obtain pro­
fessional assistance.

A WARNING
Fuel is highly inflammable and can cause
seri­

ous burns and other injuries.
- For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
The canister could become damaged in an
accident and Leak.
- Observe all relevant statutory regulations
on using, storing and transporting spare
fuel canisters.
- When filling your tank or
a
spare fuel canis­
ter with
fuel,
do not smoke and keep away
from naked flames
-
risk of explosion!
- If, in exceptional circumstances, you have
to

carry
a
spare fuel canister, please observe
the following warnings:
- Never
filL
fuel into the spare fuel canister
with the canister placed in or on top of the
vehicLe. An electrostatic charge could
build up during filling, causing the fuel va­
pour to ignite
-
risk of explosion! Always
place the canister on the ground to fill
it.

- Insert the filler nozzle as far as possibLe
into the spare fuel canister.
-
If
the spare fuel canister is made of metal,
the filler nozzle must be in contact with
the canister during filling. This helps pre­
vent an electrostatic charge building up.

vapour is explosive - danger to life!
© Note
(7) CAUTION
- If any fuel is spilt onto the vehicle, it should
be removed immediately as it could other­
wise damage the paintwork.
- Never run the tank completely dry. If there
is an irregular fuel supply, misfiring can oc­
cur. As a result unburnt fuel can enter the
exhaust system and cause damage to the
catalytic converter(s).
- Applies to vehicles with diesel engine: When
filling the fuel tank after having run it com­
pletely dry, the ignition must be switched
on for at least 30 seconds before the engine
is started. When you then start the engine it
may take longer than normal (up to one mi­
nute) for the engine to start firing. This is
because air needs to be bled from the fuel
system while starting.
® For the sake of the envir
Do not try to put in more fuel after the auto­
matic filler nozzle has switched off; this may
cause the fuel to overflow if it becomes warm.

(T)
Note
Applies to: vehicles with diesel engine
Diesel vehicles are equipped with an incorrect
fuelling protection
system1).
This system en­
sures that the tank can only be fuelled from a
diesel filler nozzle.
- If the filler nozzle is old, damaged or too

small,
it may not be able to open the pro­
tection mechanism on the fuel tank. In this

case,
try turning the filler nozzle before in­
serting it in the fuel filler neck, use a differ­
ent filling pump or seek professional assis­

tance.

- The protection mechanism will not open if
you try to add fuel from a spare fuel canis­
ter. You can get round this simply by adding
the diesel fuel slowly.

Checking and topping up fluids
Selective catalytic
reduction (AdBLue/DEF)
General notes
Applies to: vehicles with selective catalytic reduction
On vehicles with selective catalytic reduction, a
urea solution (AdBLue/DEF) is injected into the
exhaust system upstream of
a
NOx catalytic
con­

verter in order to reduce nitrogen oxide emis­

sions.
The urea solution is known under the name
of AdBlue or DEF (Diesel Exhaust Fluid). The term
AdBlue is used below.
The AdBlue is held in a separate tank on the
vehi­

cle.
AdBlue consumption is approximately 1.0 -
2.5% of diesel fuel consumption.
As soon as a message appears in the instrument
cluster display reminding you to refill AdBlue,
you must refill the AdBlue tank or have this done
by
a
qualified workshop
