Driving

Driving
General information
A new vehicle must be broken in within the first
1,000 miles (1,500 km) so that all moving parts
work smoothly together, which helps to increase
the service life of the engine.
Do not drive higher than two-thirds of the maxi-
mum permitted engine RPM during the first 600
miles (1,000 km) and do not use full accelera-
tion. The engine can be increased RPM gradually
during the next 300 miles (500 km).
Reducing the risk of vehicle damage
@ Note
When driving on poor roads, over curbs, and
on steep ramps, make sure that components
that hang below the vehicle, such as the spoil-
er and exhaust system, are not struck because
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 driving through water, for example
on flooded roads:
— The water must not be any higher than the bot-
tom of the vehicle body.
— Do not drive faster than walking speed.

ZA 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 and restore the full braking effect.


@) 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 62.
@) 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.
aie e TRE erelie ltr)

driving
The amount of fuel consumption, the environ-
mental impact, and the wear to the engine,
brakes, and tires depends mostly on your driving
style. Note the following information for efficient
and environmentally-conscious driving:
— Do not let the engine run while the vehicle
parked.
— Use the Start/Stop system > page 62.
— 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.
— Utilize the engine braking effect.
— Avoid driving short distances or at high speeds
when possible.
— 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.
— Have maintenance performed regularly on the
vehicle.
— Do not drive with winter tires during the summ-
er.
— Make sure the tire pressure is correct
=> page 254.

Driving

@ 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.
Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.

ZA 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,
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 an au-
thorized Audi dealer or authorized Audi

60

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.

Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You could
damage the engine.

@) For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This re-
duces unnecessary emissions.
G) Tips
— Some noise after starting the engine is nor-
mal and is no cause for concern.
— If you leave the vehicle with the ignition
switched on, the ignition will switch off af-
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button.



)_ This function is not available in all countries.
Steering lock!)
The steering is locked when you switch off the en-
gine and open the driver's door. The locked steer-
ing helps prevent vehicle theft.

Z\ WARNING
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You may need to use more
force when braking or steering. Because you
cannot brake and steer as you usually would,
this could lead to accidents and serious inju-
ries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. If you
do not do this, the engine could be started
and electrical equipment such as the power
windows could be activated. This can lead to
serious injuries.
— For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally.
() Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
@) Tips
For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again auto-
matically or it may continue to run, even if the
ignition is switched off.

Start/Stop system
Applies to: vehicles with Start/Stop system
The Start/Stop system can help increase fuel
economy and reduce CO2 emissions.
In Start/Stop mode, the engine shuts off auto-
matically when the vehicle is stopped, such as at
a traffic light. The ignition remains switched on
during this stop phase. The engine will restart
automatically when needed.

4S1012721BA
Driving

The Start/Stop system is automatically activated
once
the ignition is switched on.
Basic requirements for Start/Stop mode
— The driver's door must be closed.
— The driver's seat belt much be fastened.
— The engine compartment lid must be closed.
— The vehicle must have driven faster than 2 mph
(4 km/h) since the last time it stopped.

Z\ WARNING
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You would then need to use
more force to steer and brake the vehicle.
The fact that you cannot steer and brake as
usual may increase the risk of accidents and
serious
injuries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. This
applies particularly when children remain in
the vehicle. Otherwise the children could
start the engine or operate electrical equip-
ment such as power windows.
