@ Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires. Uncom­
busted fuel will then enter the exhaust sys­
tem. Th is can cause overheating and damage
to the catalytic converter.

A WARNING
-- Read and follow the warnings in
¢ page 233, Working in the engine com­
partment
before opening the hood and
checking the brake fluid level.
- If the brake system indicator light does not
turn off or it turns on while driving, the
brake fluid level in the reservoir is too low,
and this increases the risk of an accident .
Stop the vehicle and do not continue driv­
ing. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- If the brake system indicator light turns on
together with the ABS and ESC indicator
lights, the ABS/ESC regulating function may
be malfunctioning. Functions that stabilize
the vehicle are no longer available. This
could cause the rear of the vehicle to
swerve, which increases the risk that the ve­
hicle will slide. Drive carefully to the nearest
authorized Audi dealer or authorized Audi
Service Facility and have the malfunction
corrected.

A WARNING
No one, especially children, should stay in the
vehicle when it is locked from the outside, be­
cause the windows can no longer be opened
from the inside <=> page
2 7. Locked doors
make it more difficult for emergency workers
to get into the vehicle, which puts lives at
risk.
(D Tips
- Only use the remote control key when you
are within view of the vehicle .
- Do not use the remote control when you are
inside the vehicle. Otherwise, you could un­
intentionally lock the vehicle. If you then
tried to start the engine or open a door, the
alarm would be triggered. If this happens,
press the unlock
button @.
-The selector lever must be in the P position
on vehicles with a convenience key*; other­
wise the vehicle will not lock.
- Only use the panic function in an emergen­
cy.
Unlocking/locking with the convenience
key
Applies to: vehicles with convenience key
The doors and luggage compartment lid can be
unlocked/locked without using the remote con­
trol key.

dle. It makes no difference whether the master
key is in your jacket pocket or in your briefcase,
for example .
If you hold the door handle while locking, this
can impair the locking func tion .
The door cannot be opened for a brief period di­
r ectly after locking i t. This way you have the op­
portunity to check if the doors locked correctly.
The settings in the Infotainment system deter­
mine if the entire vehicle or only one of the doors
is unlocked when unlocking the vehicle
