Important: A special anti–seize compound is used on
the oxygen sensor threads. This compound consists of
a liquid graphite and glass beads. The graphite will burn
away, but the glass beads will remain, making the sen-
sor easier to remove. New or service sensors will al-
ready have the compound applied to the threads. If a
sensor is removed from any engine and if for any reason
it is to be reinstalled, the threads must have anti–seize
compound applied before reinstallation.
2. Install the oxygen sensor.
Tighten
Tighten the oxygen sensor to 35~44 Nm (26~33 lb-
ft).

WARNING LAMP OPERATION
This brake system uses a BRAKE warning lamp located
in the instrument panel cluster. When the ignition switch
is in the III position, the BRAKE warning lamp should
glow and then go OFF when the ignition switch returns
to the II position.The following conditions will activate the BRAKE lamp:
