Opening and closing
Key set
Fig. 25 Your veh icle key set
@ Remote control key with integrated
mechanical key
You can unlock/lock your veh icle w ith the remote
control key . A mechan ical key is integrated in the
remote control key~
page 39.
@ Key fob with vehicle code
Applies to veh icles with Audi connect vehicle control
Open the key tag and scratch to reveal the veh icle
code . You can unlock the Audi connect vehicle
control se rvices* for your vehicle with this vehicle
code . For additional information, refer to
~ page 181 .
Replacing a key
If a key is lost, see an authorized Audi dealer or
authorized Audi Service Facility. Have
this key de­
activated .
It is important to bring all keys with
you .
If a key is lost, you should report it to your
insurance company.
Number of keys
You can check the number of keys assigned to
your vehicle in the Infotainment system . To do
this, select the
IM ENU I button > Vehicle > left
control button
> Service & checks> Vehicle in·
formation .
This way, you can make sure that you
have all the keys when purchasing a used vehicle.
Electronic immobilizer
The immob ilizer prevents unauthorized use of
the vehicle .
Under certain circumstances, the vehicle may not
be able to start if there is a key from a different
veh icle manufacturer on the key chain.
38
Data in the master key
When driving, service and maintenance-re levant
data is continuously stored in your remote con­
trol key. Your A udi service advisor can read out
this data and tell you about the work your vehicle
needs . This applies also to vehicles with a con­
venience key*.
Personal convenience settings
If two people use one vehicle, it is recommended
that each person always uses "their own" remote contro l key. When the ignition is switched off or
when the vehicle is locked, personal convenience
settings for some systems are stored and as­
s igned to the remote control key .
The stored settings are automatically recalled
when you unlock the vehicle, open the doors or
turn on the ignition.
_&. WARNING
Always take the vehicle key with you when leaving the vehicle, even for a short period of
time. This applies particularly when children
r ema in in the vehicle . Otherwise the children
could start the engine or operate elec trical
equipment such as power windows.
(D Tips
-
The operation of the remote control key can
be temporarily disrupted by interference from
transmitters in the vicinity of the vehicle
working in the same frequency range (such as
a cell phone or radio equipment) . Always
check if yo ur vehicle is locked!

Driving
next traffic light is red . This produces an engine
braking effect, which helps to protect the brakes
and tires and reduces the emissions and fue l con ­
sumpt ion to zero (fuel shut-off during decelera­
t ion).
Shift effici ently
An effective way to save fuel is to upshift earlier.
Staying in a gear too long uses fue l unnecessari ­
ly .
P ress down o n the acce lerator peda l slowly and
avoid "kick -down".
Avoid full acceleration
You shou ld rare ly t rave l at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh inc rease in fuel consump tion, emissions and
traffic no ise . Slower driving saves fuel.
Reduce idling time
The Start/Stop system* he lps to reduce the idling
time automatically. In vehicles witho ut the Start/
S top system* , it is efficient to swit ch the eng ine
off when stopped at r,;1ilro,;1d crossi ngs and long
red lights . Stopping the engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the engine.
It t akes a very long time in idle to war m the en ­
g ine up to opera ting tempera ture . Wea r and
emissions are especially high in the warm -up
p hase . Therefore, yo u should begin driving im ­
mediately after starting the engine. Avoid high
RPMs while do ing th is.
Have maintenance performed regularly
By having ma intenance performed regularly on
your vehicle, you can help to reduce f uel con­
sumpt ion befo re yo u even start to dr ive. The
maintenance condition of your vehicle not only
affects t raffic safety and long-term value but a l­
so impacts
fuel consumpt ion . A poorly main ­
tained engine can lead to f uel consumption that
is 10% higher than normal.
Avoid short trips
The engine and exhaust cleaning system m ust
reach the ir opt imal
operating temperature to ef­
fectively reduce consumption and em iss ions.
74
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption norma lizes on ly
after approximate ly
four ki lometers.
Check the tire pres sure
To save fue l, make sure the t ires are always in­
flated to the correct press ure
¢ page 32 7. The
fuel consumpt ion can increase by S% if the pres ­
s u re is only 0.5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
l ead to greater tire
wear and will affect dr iving
behavior.
Do not drive on
winter tires year-round, as this
will consume up to 10% more f uel.
Eliminate unnecessary we ight
Since eve ry kil og ram o f extra weight in creases
fuel consumption, a quick inspection of the lug­
gage compartment may be worth it to avoid un­
necessary we ight.
When no t be ing used, a roof rack sho uld be re ­
moved to decrease the wind resistance of the ve­
hicle . You will save approx imately
12% of your
fuel when at speeds from 62-75 mph (100-120 km/h).
Save energy
The eng ine drives the generator, which generates
electricity; the fuel consumption also inc reases
with the demand for e lectricity. Therefore, switch
e lectrical equ ipment off when you no longer
need it. Examples of eq uipment 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 shou ld come on to
i ndica te improper operation, they would go
unheeded . Extended idling also prod uces
h eat, w hic h could result i n overheating o r
o ther damage to the veh icle o r othe r prope r­
ty .

(D Note
-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.
{t) 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 adjustable up and
down and forward and back .
Fig. 76 Lever on the steeri ng col umn
.. Pull the lever in the direction of the arrow
¢,&. .
"'Bring the steering wheel into the desired posi­
tion.
Driving
.. 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 a 10 in (25 cm) dis­
tance between your chest and the steering
wheel. If you do not maintain this distance
I
you will not be properly protected by the air­
bag system.
- If your physical characteristics prevent you
from sitting at least 10 in (25 cm) or more
away from the steering wheel, see if your
authorized Audi dealer or authorized Audi
Service Facility can provide adapters that
will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure that the steering 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 steering wheel incorrectly sig­
nificantly increases the risk of injury to the
hands, arms and head if the airbag deploys.

Trailer towing
Backing up is difficult and requires practice .
Backing up with a trailer generally requires steer­
ing action oppos ite to that when backing up your
veh icle w ithout a trailer .
Maintain a g reater distance between your vehicle
and the one in front of you. You w ill need more
room to stop. To compensate for the tra iler, you
will need a larger than normal turn ing radius.
When passing, remember that you cannot accel ­
erate as fast as you norma lly would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your tra iler before chang ing lanes again .
Avoid jerky starts , sharp turns or rapid lane
changes .
@ Tips
- Do not tow a trailer during the break -in per i­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance d ue to the ex ­
tra load
~ page 363.
Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only o~er doing the following:
When parking:
.. Apply t he foo t brake .
.. Have someone place chocks under both t he ve­
hicle and the tra ile r whee ls .
.. With chocks in p lace, slowly release t he brakes
u ntil the whee l chocks absorb the load .
.. Turn the wheels towards the curb .
.. Apply the parking brake .
.. Move the selector lever to P .
When restarting after pa rking:
.. Apply the foot brake .
.. Start the engine .
.. Move the selector lever to D/S .
.. Release the parking brake and slowly pull out
and away from the wheel chocks .
.. Stop and have someone retrieve t he wheel
chocks .
