Door Side Airbag Sensor RH Initialization Incomplete (B1693/81,B1698/82)
DESCRIPTION
The circuit for the side collision sensor LH or RH (to determine deployment of
the front seat side airbag LH or RH and curtain shield airbag LH or RH) is composed
of the center airbag sensor, rear airbag sensor LH or RH and side airbag sensor ...
Locking the doors from the outside without a key
Move the inside lock button to
the lock position.
Close the door.
Vehicles without a smart key system
The door cannot be locked if either of the front doors is open and the key is
in the engine switch.
Vehicles with a smart key system
The door can ...
