Advice
Remote control
The high frequency remote control is a
sensitive system; do not operate it while
it is in your pocket as there is a possibility
that it may unlock the vehicle, without you
being aware of it.
Do not press the buttons of your remote
control out of range and out of sight of
your vehicle. It might stop working. It will
then be necessary to reinitialise it again.
Electrical interference
The Keyless Entry and Starting electronic
key may not operate if close to certain
electronic devices: telephone, laptop
computer, strong magnetic fields, etc.Anti-theft protection
Do not make any modifications to the
electronic engine immobiliser system;
this


could cause malfunctions.
Locking the vehicle
Driving with the doors locked could make
it difficult for the emergency ser vices to
enter the vehicle in an emergency.
As a safety precaution (with children on
board), take the electronic key with you when
you leave the vehicle, even for a short time.
Lost keys, remote control, electronic
key
Go to a PEUGEOT dealer with the
vehicle's registration document, your
personal identification documents and if
possible the key code label.
The PEUGEOT dealer will be able to
retrieve the key code and the transponder
code required to order a new key. Do not throw the remote control batteries
away, they contain metals which are
harmful to the environment.
Take them to an approved collection
point.
