Fig. 82 2-zone deluxe automatic climate control: controls
The functions can be switched on and off by
pressing the buttons or adjusted by turning the
knob. The LED in a button will light up when the
function is switched on.
The deluxe climate control system automatically
maintains a temperature once it has been set. In
all heating mode functions except defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera-
ture.
AUTO Automatic mode or eco mode*
Automatic mode maintains a constant tempera-
ture inside the vehicle. Air temperature, airflow
and air distribution are controlled automatically.
AUTO mode switches off once a button in the cli-
mate control system is pressed.
Applies to: vehicles with eco mode: Pressing the
AUTO button briefly when automatic mode is ac-
tive will activate the energy-saving mode of the
climate control system. eco will appear on the
control panel display. You can end eco mode by
pressing the AUTO button again.
A/C cooling mode
The cooling mode only functions with the blower
turned on. You can turn the cooling system on or
off by pressing the A/C button. The air is not
cooled and humidity is not removed when cooling
66
mode is switched off. This can cause fog on the
windows. The cooling mode switches off auto-
matically when there are cold outside tempera-
tures.
@ / @ Temperature
The temperature for the driver's and front pas-
senger's side can be adjusted separately with the
dials @/@). Temperatures between 60 °F
(+16 °C) and 84 °F (+28 °C) can be set. If outside
of this range, LO or HI will appear in the climate
control system display. In both settings, the cli-
mate control runs constantly at the maximum
cooling or heating level. The temperature is not
regulated.
Synchronization: Pressing and holding the AUTO
button for two seconds transfers the tempera-
ture setting for the driver to the front passeng-
er's side. This applies a temperature change to
the front passenger's side.
S8 Blower
Using the dial $8, you can manually adjust the
volume of air generated by the blower to your
preference. The blower should always run at a
low setting to prevent the windows from fogging
and to ensure a continuous exchange of air inside
the vehicle. To have the blower regulated auto-
matically, press the AUTO button.

Driving

— Turn off electrical equipment that is not need-
ed, for example seat heating*.
— Anticipate upcoming traffic situations while
driving to avoid unnecessary acceleration and
braking.
— Avoid driving at high speeds.
— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
— Plug-in hybrid drive: brake early and evenly to
use the recuperation function.
@) Tips
The amount of noise produced by the vehicle
can increase significantly when driving with a
sporty style. Show respect to others around
you and the environment with the way you op-
erate your vehicle, especially at night.
Energy management
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
G) Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
82
electrical equipment will be limited or
switched off.
S Engine stopped: power steering and brake
booster not possible
There is a malfunction in the engine or the fuel
supply. More force is needed to steer and brake
the moving vehicle when the engine is stopped.
If the vehicle is rolling, try to bring it to a stop off
to the side from moving traffic. See an author-
ized Audi dealer or authorized Audi Service Facili-
ty for assistance.
EB EB Drive system: malfunction! Safely stop
vehicle
There is a malfunction in the plug-in hybrid sys-
tem. The brake booster and the power steering
may stop working. Stop the vehicle immediately
at a suitable location or as soon as possible. Park
the vehicle in a safe place outdoors that is not
near buildings, roof overhangs, carports or simi-
lar structures. Switch the ignition off. Have the
problem corrected by an authorized Audi dealer
or authorized Audi Service Facility.
B i B Electric drive: overheated! Safely stop
vehicle and check coolant
The coolant level is too Low or the coolant tem-
perature is too high. Stop the vehicle in the out-
doors as soon as it is safely possible. Switch the
ignition off.
Read the important safety precautions > A in
Coolant on page 312 and check the coolant level
= page 312. If the coolant level is OK, the mal-
function may be caused by the system overheat-
ing. Let the vehicle's electric drive system cool
down for some time.
— If the message turns off after cooling down and
switching the ignition back on, you can contin-
ue driving. Contact an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.
— If the indicator light stays on, contact an au-
thorized Audi dealer or authorized Audi Service
Facility.

Trailer towing

Exterior lighting
Follow the legal regulations regarding the light-
ing equipment on your trailer. Contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty for more information.
Before you start driving, check all lighting equip-
ment on the trailer while it is hitched to the vehi-
cle.
The headlight range control automatically ad-
justs the light range of the headlights.
Safety chains
Make sure the safety chains are correctly applied
when pulling a trailer. The chains should hang
enough so that the trailer can drive around
curves. However, they must not touch the
ground.
G) Tips
— Block the wheels with chocks when parking
on inclines if the trailer is loaded.
— Having the vehicle inspected between the
inspection intervals is recommended if you
tow a trailer frequently.
— Avoid driving with a trailer during the vehi-
cle break-in period.
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations specific to the country.
As the speed increases, the driving stability of
the trailer decreases. Therefore you should not
exceed the maximum legal speed limit when
there are unfavorable road, weather, and/or wind
conditions. This especially applies when driving
downhill.
Hill
When you start driving uphill or downhill, trailers
may tilt or sway sooner than when driving ona
level surface. If small swaying movements have
already occurred, you can stabilize the trailer by
114
firmly braking immediately. Never attempt to
“straighten out” the trailer by accelerating.
Downshift before driving on hills to utilize the en-
gine braking effect > A\.
Brakes
When using a trailer with overrun brakes, first
brake gently then quickly. This reduces the risk of
jerking while braking if the trailer wheels lock up.
Engine coolant temperature
Pay attention specifically to the coolant tempera-
ture display when there are high outside temper-
atures, and when driving on long inclines
=> page 15. Shift to a higher gear in a timely man-
ner.

Z\ WARNING
Constant braking causes the brakes to over-
heat and can substantially reduce braking per-
formance, increase braking distance, or cause
complete failure of the brake system.

Checking and Filling


— Maintain enough distance when you are re-
moving the oil drain plug. While doing this,
keep your forearm parallel to the ground to
reduce the risk of hot oil dripping down your
arm.
— Drain the oil into a container designed for
this purpose that is large enough to hold the
full amount of oil in your engine.
— Engine oil is poisonous. Always store out of
reach of children.
— Prolonged contact of used engine oil with
the skin may cause skin damage. Always
wash oil off immediately with soap and wa-
ter to protect your skin.
@) Note
Do not mix any additives with the engine oil.
Additives may cause engine damage that is
not covered by your New Vehicle Limited War-
ranty.

() For the sake of the environment
— Before changing the engine oil, make sure
you can dispose of the used engine oil cor-
rectly.
— Engine oil must always be disposed of cor-
rectly. Do not dump it in the yard, in the for-
est, or in open water, river channels, or sew-
ers.
— Have your used engine oil recycled by bring-
ing it to a used oil collection site or contact
a gas station.
Cooling system
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed.
The coolant level is monitored through the B in-
dicator light > page 311. However, occasionally
checking the coolant level manually is recom-
mended.

Checking and Filling

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.
— Due to the risk of engine damage, the cool-
ing system should only be refilled by an au-
thorized Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or
authorized Audi Service Facility can also pro-
vide you with important information about
the recommended coolant additive.
@® Tips
Applies to: RS models: In certain weather
conditions, moisture such as rain or snow may
evaporate on the radiator after stopping the
vehicle. This may cause steam to escape from
the front of the vehicle.
Applies to: vehicles with plug-in hybrid drive

Checking and Filling

> Check the coolant level in the coolant expan-
sion tank > page 307, fig. 248 using the outer
markings (2) > fig. 252. The coolant level must
be between the markings (2) when the engine is
cold. When the engine is warm it can be slight-
ly above the upper marking.
Adding coolant
Applies to: vehicles with plug-in hybrid drive:
Your vehicle has two coolant expansion tanks
that are separate from each other. The smaller of
the two expansion tanks must not be opened
= page 312. Read and follow the important safe-
ty precautions > A\ in Coolant on page 312.
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.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cover.
> Remove the cover (@) © fig. 252 carefully to the
left > AX.
» Add the correct mixture ratio of coolant
> page 311 up to the upper marking @
> fig. 252.
> 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.

— 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.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store 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.
