AUDI A3 SEDAN 2017 Manual PDF

-Only a specially designed roof rack may be used
on your vehicle. These roof racks are the basis
for a complete roof rack system. Additional at ­
tachments/carrier systems are necessary to
transport luggage and sports equipment. We
recommend roof racks and attachments from
the Aud i Genu ine Accessor ies program.
-When installing the roof rack, make sure that it
is mounted only at the designated points on
the roof
c::> fig. 84, c::> fig . 85 .
-The permissible roof load for your vehicle is
165 lb (7 5 kg). The roof load is the total of the
weight of the roof rack, the attachments and
the cargo you are carrying. However, you must also note the permitted load of the ca rr ier sys­
tem being used. The permitted axle load and
the permitted tota l vehicle weight .
A WARNING
-Follow the installation instructions provided
with the roof rack system. If you do not se­
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and cause an acc ident .
-Using a roof rack system increases the risk
of an accident, because it changes the dr iv­
ing characterist ics by shifting the center of
gravity and/or the inc reas ing the surface
area exposed to wi nd. Adapt your driving
and speed to the current conditions .
(D Note
-If you use other roof luggage rack systems
or do not install the racks as intended, any
damage to the veh icle is not cove red by the
war ranty. Careful ly follow the assembly and
i nsta llation inst ruct ions included with the
roof rack carrier system .
-Make sure t hat the luggage comp artment
li d and the panorama glass roof * do not
come into contact with objects on the roof
when they are open .
@ For the sake of the environment

Warm and cold
Warm and cold Climate control system
Description
The climate control system circulates, warms or
cools, and removes humid ity from the air in the
veh icle inter ior .
It is the most effective when the
windows and panorama glass roof* or power top*
are closed. If there is a build-up of heat inside
the vehicle, ventilation can help to speed up the
cooling process.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the a ir.
Key recognition
Various settings are stored and assigned to the
remote control key be ing used .
These settings are different when the power top* is open or closed .
Presetting
Several functions can be preset in the Infotain­
ment system.
Select in the Infotainment system:
I MENU I but­
ton
> Vehicle > left control button > Air condi­
tioning
A WARNING
Poor visibility can lead to accidents .
- For safer driving, keep all windows free of
ice, snow and fog.
- Become familiar with the correct use and
function of the climate control system as
quickly as possible, especially with the de­
frosting and defogging functions.
- When the temperature is below freezing, only use the windshield washer system after
70
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­
ty .
Cl) Note
-If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools . See an authorized Aud i dealer
or authorized Aud i Service Facility .
@ For the sake of the environment
-To save fuel, turn off the climate control
system cooling mode by press ing the A/C
button. This will also reduce emissions . The
climate control system is off when the LED
in the button turns off.
- In vehicl es w ith the efficiency prog ram*,
you can find other consumption information
and more economy tips <=? page 19.
(D Tips
- T o prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
drip and form a pudd le of water under the
vehicle. This is norma l and does not mean
there is a leak.
- The energy management system may tem­
porarily switch off certain functions, such as
the seat heating* or rear window defogger.
These systems are available again as soon
as the energy supply has been restored.

General information
Breaking in
A new vehicle must be broken in for the first 1,000 mi les (1,500 km). Do not drive at speeds
that will exceed 2/3 of the maximum perm itted
engine speed (RPM) for the first 600 miles
(1,000 km), and avoid full acceleration during
this period . You may gradually start increasing
the RPM and the speed between 600 miles (1,000 km) and 1,000 miles (1,500 km) .
During the first hours of use, the engine has a
h igher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in period, particularly when running a cold
engine. This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (RPM).
Shift down if the engine stops running "smooth­ ly". Extremely high engine speeds are automati­
cally reduced .
Reducing the risk of vehicle damage
CD Note
When driving on poor roads, by curbs and on
steep ramps, make su re that low-hang ing
components such as the spoi ler and exhaust
system do not come into contact with these
or they could be damaged. This especially ap­
plies to vehicles with low ground clearance
and vehicles that are heavily loaded.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driv ing through water, for example
on flooded roads:
-The water must not be any higher than the bot­
tom of the vehicle body .
74
-Do not drive faster than walking speed .
A WARNING
After driving through water or mud, the effec­
tiveness of the brakes may be reduced due to
moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes.
CD Note
-Vehicle components such as the engine,
transmission, suspension or electrical sys ­
tem can be severely damaged by driving
through water .
-Always switch the Start/Stop system* off
when driving through water
¢page 81.
(i) Tips
-Determine the depth before driving through
water.
-Do not stop the vehicle, drive in reverse or
switch the engine off when driving through
water.
-Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely.
- Avoid driving through salt water, because
this can cause corrosion .
Economical and environmentally-friendly
dr iving
The amount of fuel consumption, the environ­
mental impact and the wear to the engine,
brakes and tires depends mostly on your driving
sty le. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­
proximately 10-15%. The following tips will help
you conserve the environment and your money at
the same time .
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged,
for example, when you notice that the ..,.

CXl CXl .... N ,.__
N .... 0 N > 00
next traffic light is red. This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (fuel shut-off during decelera­
tion).
Shift efficiently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fuel unnecessari­
ly .
Press down on the accelerator pedal slowly and
avoid "kick-down".
Avoid full acceleration
You should rarely travel at the maximum vehicle
speed. High speeds cause a disproportionately
high increase in fuel consumption, emissions and
traffic noise. Slower driving saves fuel.
Reduce idling time
The Start/Stop system* helps to reduce the idling
time automatically. In vehicles without the Start/
Stop system, it is efficient to switch the engine
off when stopped
at railroad crossings and long
red lights. Depending on the version of the en­
gine, stopping the engine for as little as five sec­
onds once it has reached operating temperature
still saves more fuel than leaving the engine run­ ning
-even when taking into account the amount
of extra fuel that is used to restart the engine.
It takes a very long time in idle to warm the en­
gine up to operating temperature. Wear and
emissions are especially high in the warm-up
phase. Therefore, you should begin driving im­
mediately after starting the engine. Avoid high
RPMs while doing this.
Have maintenance performed regularly
By having maintenance performed regularly on
your vehicle, you can help to reduce fuel con­
sumption before you even start to drive. The maintenance condition of your vehicle not only
affects traffic safety and long-term value but al­
so impacts
fuel consumption. A poorly main­
tained engine can lead to fuel consumption that
is 10% higher than normal.
Driving
Avoid short trips
The engine and emissions control system must
reach their optimal
operating temperature to ef­
fectively reduce consumption and emissions.
A cold engine uses a disproportionately high
amount of fuel. The engine reaches operating
temperature and consumption normalizes only
after approximately 2.5 miles (4 km).
Check the tire pressure
To save fuel, make sure the tires are always in­
flated to the correct pressure
r=;, page 33 5. The
fuel consumption can increase by S% if the pres­
sure is only 0.5 bar too low. Due to the increased
rolling resistance, low tire pressures will also
lead to greater tire
wear and will affect driving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more fuel.
Eliminate unnecessary weight
Since every kilogram of extra weight increases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary weight.
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62-75 mph
(100-120 km/h).
Save energy
The engine drives the generator, which generates
electricity; the fuel consumption also increases
with the demand for electricity. Therefore, switch
electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
(D Note
- Do not leave engine idling unattended after
starting. If warning lights should come on
to indicate improper operation, they would go unheeded. Extended idling also produces
heat, which could result in overheating or
IJ,-

Driving
other damage to the vehicle or other property .
-Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in your Warranty
& Maintenance book­
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer .
- Do not alter or remove any device, such as
heat shields, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components.
(I) Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
load and speed, road and weather conditions,
trip length, etc .
Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back .

.,. Push the lever against the steering column un­
til it is secure.
A WARNING
Incorrect use of the steering wheel adjust­ ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the
vehicle is stationary so that you do not lose control of the vehicle .
-
-Adjust the driver's seat or steering wheel so
that there is at least 10 inches (25 cm) dis­
tance between your chest and the steering
wheel
c:::;, page 248, fig. 222 . If you do not
maintain this distance, the airbag system
will not be able to provide its full protec­
tion .
c:::;,page248, fig. 222.
- If your physical characte ristics prevent you
from s itting at least 10 inches (25 cm) or
more away from the steering whee l, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters
that will help.
- If your face is level with the steering whee l,
the airbag does not provide as much protec­
tion during a collision. Always make sure
that the steer ing wheel is level with your
chest.
- Always hold the steering wheel with your
hands in the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steering wheel in the 12
o'clock position or with both hands on the
rim or the center of the steering wheel.
Holding the steer ing wheel incorrect ly sig­
nificant ly increases the r isk of injury to the
hands, arms and head if the airbag deploys.

Driving
_& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
t ion of the brake booster and the power
steering is not guaranteed. Yo u must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and ser i­
ous injuries.
- Never remove the ignit ion key from the ign i­
tion lock while the vehicle is moving. Other ­
wise, the steering lock cou ld sudden ly en­
gage and you would not be able to steer the
vehicle.
- Always take the key with you whenever you
leave your vehicle. Otherw ise, the engine
could be started or electrical equipment
suc h as the power windows could be operat­
ed . This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position .
Otherwise, there is the r isk that the vehicle
could roll unintentionally.
(D Note
If the engine has been under heavy load for
an extended per iod of t ime, heat builds up in
the engine compartment after the engine is
sw itched off and there is a risk of damaging
the engine. For this reason, let the engine run
for at idle for approximately two minutes be­
fore shut ting it off.
(0 Tips
For up to 10 minutes after stopping the en­
gine, the rad iator fan may turn on again auto­
matically or it may continue to run (even if
the is ignition switched off) due to the follow­
ing reasons:
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun ­
light.
