Driving safety

> ALWAYS adjust your speed to road, traffic and
weather conditions.
> Take frequent breaks on long trips. Do not drive
for more than two hours at a stretch.
> Do NOT drive when you are tired, under pres-
sure or when you are stressed.

ZX WARNING
Impaired driving safety increases the risk of
serious personal injury and death whenever a
vehicle is being used.
Safety systems monitoring
The Ba indicator light in the instrument cluster
monitors the safety systems such as the airbags
(including the control modules, sensors, and wir-
ing) and the belt tensioners. It turns on when you
switch the ignition on and turns off after several
seconds.

If the Ea indicator light does not turn on when
the ignition is switched on, does not turn off af-
ter several seconds, or turns on or flashes while
driving, there may be a malfunction in one of the
safety systems. Drive to an authorized Audi deal-
er or authorized Audi Service Facility immediately
to have the malfunction corrected.

Z\ WARNING
Have the malfunction in the safety systems in-
spected immediately. Otherwise, there is a
risk that the systems may not activate during
an accident, which increases the risk of seri-
ous or fatal injury.

Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving.

B4G-0375



Fig. 198 Correct seating position
For your own safety and to reduce the risk of in-
jury in the event of an accident, we recommend
that you adjust the driver's seat to the following
position:
> Adjust the driver's seat so that you can easily
push the pedals all the way to the floor while
keeping your knee(s) slightly bent > A\.
> Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact with it when you drive.
> Adjust the steering wheel so that there is a dis-
tance of at least 10 inches (25 cm) between the
steering wheel and your breast bone © fig. 198.
If not possible, see your authorized Audi deal-
ership about adaptive equipment.
> Adjust the steering wheel so that the steering
wheel and airbag cover points at your chest and
not at your face.
> Grasp the top of the steering wheel with your
elbow(s) slightly bent.
> For adjustable head restraints: Adjust the head
restraint so the upper edge is as even as possi-
ble with the top of your head. If that is not pos-
sible, try to adjust the head restraint so that it
is as close to this position as possible. Move the
head restraint so that it is as close to the back
of the head as possible.
> Fasten and wear safety belts correctly
=> page 248.

Checking and Filling

> After the fuel pump has switched off, wait five
seconds before removing the nozzle to allow
the rest of the fuel to finish dripping into the
fuel tank.
> Turn the fuel cap clockwise until it clicks into
place.
> Close the fuel filler door and then press on the
left side until it latches.
The correct fuel type for your vehicle can be
found ona label located on the inside of the fuel
filler door. For additional information on fuel, see
=> page 298.
For the tank capacity in your vehicle, refer to the
Technical Data > page 380.
To reduce the risk of fuel leaking out or vapors
escaping, make sure that the fuel tank is closed
correctly. Otherwise the Ey indicator light will
turn on.
If the central locking system malfunctions, there
is a fuel filler door emergency release
= page 301.
Messages
Plug-in hybrid drive: for additional information
on refueling, see > page 302.
| Tank system: malfunction! Please contact
Service
There is a malfunction in the fuel tank system.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
malfunction corrected.

— If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire.
— Never get into the vehicle when refueling. If
there is an exceptional situation where you
must enter the vehicle, close the door and
touch a metal surface before touching the
fuel pump nozzle again. This will reduce the
risk of electrostatic discharge that can cause
flying sparks. Sparks can start a fire when
refueling.


ZA\ WARNING
Improper fueling procedures and improper
handling of fuel can lead to explosions, fires,
severe burns, and other injuries.
— Do not smoke. Keep away from open flames.
— The ignition must be switched off when re-
fueling.
— Mobile devices, radio devices, and other ra-
dio equipment should always be switched
off when refueling. Electromagnetic rays


ZA WARNING
Transporting fuel containers inside the vehicle
is not recommended. Fuel could leak out of
the container and ignite, especially during an
accident. This can cause explosions, fires, and
injuries.
— If you must transport fuel in a fuel contain-
er, note the following:
— Always place the fuel container on the
ground before filling. Never fill the fuel
container with fuel while it is inside or on
the vehicle. Electrostatic discharge can oc-
cur while refueling and the fuel vapors
could ignite.
— When using fuel containers made of met-
al, the fuel pump nozzle must always re-
main in contact with the container to re-
duce the risk of static charge.
— Insert the fuel pump nozzle as far as pos-
sible into the filler opening while refuel-
ing.
— Follow the applicable legal regulations in
the country where you are driving when
using, storing and transporting fuel con-
tainers.
— Make sure that the fuel container meets
the industry standards, for example ANSI
or ASTM F852-86.
