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).

@) 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.
G) 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.
Efficient and environmentally-conscious

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.
— 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-
ef,
— Make sure the tire pressure is correct
=> page 250.

Airbag system

— when the electrical capacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas-
senger side frontal airbag must be switched off
by the electronic control unit (the PASSENGER
AIR BAG OFF %; light > page 200 and how they
work comes on and stays on).


ZA\ WARNING
Sitting in the wrong position can increase the
risk of serious injury in crashes.
—To reduce the risk of injury when the airbags
inflate, the driver and passengers must al-
ways sit in an upright position, must not
lean against or place any part of their body
too close to the area where the airbags are
located.
— Occupants who are unbelted, out of position
or too close to the airbag can be seriously in-
jured by an airbag as it unfolds with great
force in the blink of an eye > page 190.

Z\ WARNING
A child in a rearward-facing child seat instal-
led on the front passenger seat will be seri-
ously injured and can be killed if the front air-
bag inflates - even with an Advanced Airbag
System.
— The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the child seat and child against the
backrest, center armrest, door or roof.
— Never install a rearward facing child safety
seat on the front passenger seat unless the
PASSENGER AIR BAG OFF %; light comes
on and stays on. If the PASSENGER AIR
BAG OFF #%; light does not come on and stay
on, the inflating airbag will hit the child
safety seat or infant carrier with great force
and will smash the child safety seat and
child against the backrest, door or roof.
Have the airbag system inspected immedi-
ately by your authorized Audi dealer.

ZA WARNING
Objects between you and the airbag will in-

ing with the way the airbag unfolds or by be-
ing pushed into you as the airbag inflates.
— Never hold things in your hands or on your
lap when the vehicle is in use.
— Never transport items on or in the area of
the front passenger seat. Objects could
move into the area of the front airbags dur-
ing braking or other sudden maneuver and
become dangerous projectiles that can
cause serious personal injury if the airbags
inflate.
— Never place or attach accessories or other
objects (such as cup holders, telephone
brackets, large, heavy or bulky objects) on
the doors, over or near the area marked
“AIRBAG” on the steering wheel, instrument
panel, seat backrests or between those
areas and yourself. These objects could
cause injury in a crash, especially when the
airbags inflate.
— Never recline the front passenger's seat to
transport objects. Items can also move into
the area of the side airbag or the front air-
bag during braking or in a sudden maneuver.
Objects near the airbags can become projec-
tiles and cause injury, particularly when the
seat is reclined.
— Never place or transport objects on the front
passenger seat. Objects on the front passen-
ger seat could cause the capacitive sensor in
the seat to signal to airbag system that the
seat is occupied by a person when it in fact is
not, or that the person on the seat is heavier
than he or she actually is. The change in
electric capacitance because of such objects
can cause the passenger front airbag to be
turned on when it should be off, or can
cause the airbag to work in a way that is dif-
ferent from the way it would have worked
without objects on the seat.
— Always make sure that there is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occupied by a person when it is
not, or to signal that it is occupied by some-
one who is heavier than the person actually

tire is rated to carry for a given in-
flation pressure. You may not find
this information on all tires be-
cause it is not required by law.

tion pressure for that tire.
Maximum loaded vehicle
weight
