switch (1) in daytime mode.
Nighttime Mode

Combination meter is transferred to nighttime mode with position light request signal from BCM with CAN
communication.

Meter illumination is adjusted to 16 steps by illumination control
switch (1) in nighttime. Refer to LT- 2 9 3 , "
ILLUMINATION" .
Driver Welcome Function
Ring illumination gradually turns ON when a driver gets in the vehicle with intelligent key and closes the driver
side door.
NOTE:
Ring illumination gradually turns OFF when not turning the ignition switch ON at a certain period of time.
Engine Start Excitement Function
Combination meter detects the engine start when input engine speed signal at first. Pointers of speed meter
and tachometer sweep and ring illumination gradually turns ON when combination meter detects the engine
start. Then, combination meter starts the normal control.
NOTE:

Water temperature gauge and fuel gauge do not function.

WARNING CHIME
Revision: 2007 April2007 M35/M45
IGNITION KEY WARNING CHIME (WITH INTELLIGENT KEY)
Refer to BL-54, "WARNING FUNCTION" in intelligent key system.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, driver door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound.

BCM detects ignition switch in OFF or ACC position, front door switch (driver side) ON, and lighting switch
in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to unified meter and
A/C amp. with CAN communication line.

Unified meter and A/C amp. transmits buzzer output signal (light warning chime) to combination meter
with communication line.

When combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" .
SEAT BELT WARNING CHIME
With ignition switch turned ON and driver seat belt unfastened, seat belt warning chime will sound for approxi-
mately 6 seconds.

BCM receives seat belt buckle switch signal [seat belt buckle switch (driver side) ON] from unified meter
and A/C amp. with CAN communication line.

BCM detects ignition switch turned ON and seat belt buckle switch (driver side) ON. And then transmits
buzzer output signal (seat belt warning chime) to unified meter and A/C amp. with CAN communication
line.

Unified meter and A/C amp. transmits buzzer output signal (seat belt warning chime) to combination
meter with communication line.

When combination meter receives buzzer output signal (seat belt warning chime), it sounds the buzzer.
