ward @/().
Overriding or deactivating the cruise
control speed
Applies to: vehicles with cruise control system
You can override or deactivate the cruise control
system. When you deactivate the system, your
cruise control speed will be stored and you can
resume that speed.
Requirement: the system must be switched on
and activated.
Overriding
> To temporarily override the cruise control
speed, press the accelerator pedal.
> Once you release the accelerator pedal, the sys-
tem will adjust back to the stored cruise control
speed.
If you override the cruise control system for a
long period of time, the cruise control system
will be deactivated. The indicator light will be
displayed and the cruise control speed will be
saved.
Deactivating
> To deactivate the cruise control speed, press
the lever toward (2) (not locked into place)
=> page 110, fig. 91.
> Press the brake pedal.

ZA\ WARNING
Resting your foot on the accelerator pedal

cruise control speed will be deleted.
Requirement: the system must be switched on.
> To switch the system off, press the lever toward
@ (locked into place) > page 110, fig. 91, or
> Switch the ignition off.
Applies to: vehicles with cruise control system
Gk / 3) Speed control system: currently un-
available. See owner's manual
If the indicator light turns on and this message
appears, the cruise control system has been deac-
tivated. There is a temporary malfunction, for ex-
ample the brakes are overheating. Switch the
cruise control system on again later.
Adaptive speed/cruise
assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
The adaptive speed/cruise assist (called only
adaptive cruise assist in the vehicle display and in
the rest of the Owner's Manual) consists of a
speed and distance control system. It assists the
driver by both regulating the speed and main-
taining the set distance to the vehicle driving
ahead, within the limits of the system. If the sys-
tem detects a vehicle driving ahead, the adaptive
cruise assist can brake and accelerate your vehi-
cle within the limits of the system. On open roads
with no traffic, it functions like a cruise control
system. The stored speed is maintained. When
approaching a vehicle driving ahead, the adaptive
cruise assist automatically brakes to match that
vehicle's speed and then maintains the set dis-
tance as much as possible. As soon as the system
does not detect a vehicle driving ahead, adaptive
cruise assist accelerates up to the set speed.

Checking and Filling

® Note
— Remove fuel that has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
— Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re-
sults from that can cause engine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
the catalytic converter.
@ For the sake of the environment
— Do not overfill the fuel tank, otherwise fuel
can leak out when the vehicle is warming
up.
— Fuel should never enter the sewer system or
come into contact with the ground.
@ Tips
The fuel filler door on your vehicle does not
lock if you lock the vehicle from the inside us-
ing
the central locking switch.
Fuel filler door emergency release
If the central locking system is faulty, the fuel
filler door can be unlocked manually.


Fig. 139 Luggage compartment: Fuel filler door emergen-
cy release
The emergency release mechanism is located un-
der the cargo floor in the luggage compartment.
> Lift up the cargo floor until it engages at the
top.
> Lift up the cloth cover.
> To unlock the fuel filler door, loosen the red
loop from the retainer and then pull on the
loop carefully > fig. 139 °@.
202
> Press on the left side of the fuel filler door to
open it > page 200, fig. 137.
@) Note
Only pull on the loop until you feel resistance.
You will not hear it release. Otherwise you
could damage the emergency release mecha-
nism.
Emissions control
system
General information
ZN WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
— Never touch the exhaust tail pipes once they
have become hot. This could result in burns.

— Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the emissions sys-
tem could start a fire.
— Do not apply underbody protectant in the
exhaust system area, because this increases
the risk of fire.
Catalytic converter
Follow the safety precautions > page 202, Gener-
al information.

The vehicle may only be driven with unleaded
gasoline, otherwise the catalytic converter will be
destroyed.
Never drive until the tank is completely empty.
The irregular supply of fuel that results from that
can
cause engine misfires. Uncombusted fuel will
enter the exhaust system, which can cause over-
heating and damage to the catalytic converter.
Malfunction Indicator Lamp (MIL)
If the S indicator light blinks or turns on, there
is a malfunction that is causing poor emissions
quality and that could damage the catalytic con-
verter. Drive slowly to an authorized Audi dealer >

Checking and Filling

— 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.
Adding coolant

RAZ-0539

(diagram): @ cover; @) markings
Follow the safety precautions > page 203, Gener-
al information.
Checking the engine coolant level
>» Park the vehicle on a level surface.
> Switch the ignition off.
> Read the coolant level on the coolant expansion
tank > page 205, fig. 142. The coolant level
must be between the markings @) 9 fig. 145
when the engine is cold. When the engine is
warm it can be slightly above the upper mark-
ing.
Adding coolant
Requirement: There must be a residual amount
of coolant in the expansion tank >@).
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Let the engine cool down.
> Place a large, thick towel on the coolant expan-
sion tank cap.
210
» Remove the cover (@) > fig. 145 carefully to the
left > AX.
» Add the correct mixture ratio of coolant
> page 209 up to the upper marking @)
> fig. 145.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Screw on the cap securely to the right.
Coolant loss usually indicates there is a leak. Im-
mediately drive your vehicle to an authorized Au-
di dealer or authorized Audi Service Facility and
have the cooling system inspected. If the cooling
system is not leaking, a loss can come from the
coolant boiling through overheating and being
pushed 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 203, General informa-
tion.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases 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.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.

@) Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal-
er or authorized Audi Service Facility for assis-
tance.

Checking and Filling

The starting ability may be impaired.
If this message turns off after a little while, the
vehicle battery charged enough while driving.
If this message does not turn off, drive immedi-
ately to an authorized Audi dealer or authorized
Audi Service Facility.

ZA WARNING
When there is an electrical system malfunc-
tion, vehicle functions may not work and driv-
ing stability may be limited, which increases
the risk of an accident. Stop driving and
switch the engine off. See an authorized Audi
dealer or authorized Audi Service Facility for
assistance.


Battery
rae Le cel)
Because of the complex power supply, all work on
batteries such as disconnecting, replacing, etc.,
should only be performed by an authorized Audi
dealer or authorized Audi Service Facility > A.
Multiple batteries with different technologies
may be installed in your vehicle:
— Vehicle battery (for example, for starting the
engine, basic power supply) > page 213, Lead
battery or > page 213, Other battery types
— Auxiliary battery (for example, for recuperation
or optional equipment) > page 213, Other bat-
tery types
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. To ensure
that the vehicle can still be started, the electrical
equipment will be reduced or switched off
= page 87. Some convenience functions, 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 the ignition on and start
the
engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
212
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
= page 213. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.
Winter operation
Cold weather places higher demands on the bat-
tery. This results in reduced starting ability. Have
the battery checked by an authorized Audi dealer
or authorized Audi Service Facility before cold
weather begins.

ZA\ WARNING
All work on the battery or electrical system in
your vehicle can result in injuries, chemical
burns, accidents, or burns. Because of this, all
work must be performed only by an author-
ized Audi dealer or authorized Audi Service Fa-
cility.

C) Note
— If the vehicle will be parked for long periods
of time, protect the battery against the cold
so that it will not be destroyed by “freezing”
= page 213, Charging the battery.
— There are electrical components under the
cargo floor behind a trim panel that warm
up during operation. To reduce the risk of
the components overheating, do not store
objects such as blankets under the cargo
floor. If the components overheat, they will
switch off temporarily. This will be indicated
by a message that will be displayed in the
instrument cluster until the temperature re-
turns to normal.
