2016 AUDI A3 Key not recognized

Driving
_& WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake if. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries.
- Please note that the brake booster and pow­
er steering only work when the engine is
running. When the engine off, you must use
more force to steer or brake the vehicle. Be­
cause the usual steering and brak.ing capa­
bility is not available, the risk of accidents or
injuries increases .
- Always take the vehicle key with you when
leaving the vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle . Otherwise the
children could start the engine or operate
electrical equipment such as power win­
dows.
- 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.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off. It can also switch on again after some
time if the coolant temperature rises as the result of heat buildup or if the engine com­
partment is heated by the sun's rays and the
engine is hot.
(D 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- there is a risk of damaging the
engine. For this reason, let the engine run for
at idle for approximately two minutes before
shutting it off.
