INTERIOR LIGHT

.

INTERIOR LIGHT DIMMER CONTROL FUNCTION (THE INITIAL CONDITION: 

 

30 SECONDS)

When the interior light switch is set to the DOOR 
position, ETACS-ECU controls the interior light as 
follows.

1. When the ignition switch is OFF:

By opening any door, the light turns ON (100%), 
and dims (50%) when the door is closed, then 
and turns off after 30 seconds.
However, when the ignition switch is turned ON 
or the door lock is operated, the lights turn off at 
that time.

2. When the ignition switch is ON:

By opening any door, the light (100%) turns ON 
and OFF when the door is closed.

3. When all doors are closed, and the ignition key is 

removed

*

:

By removing the ignition key with all doors 
closed, the light turns ON 50%, and turns off after 
30 seconds. However, for the vehicles with 
TC-SST, the light is not illuminated if the ignition 
key is removed before the engine stops running 
(approximately 1 second) since the ignition 
switch was turned to the OFF position.

By inserting the ignition key again or operating 
the door lock with the light lit, the lights turns off.

NOTE: 

.

•

*

: For the vehicles with KOS, it is operated the 

same way when the IG knob is turned to OFF or 
when the emergency key is removed from the 
key cylinder. However, for vehicles with TC-SST, 
the light is turned off after approximately 1 sec-
ond (after engine stops running) since the IG 
knob was turned OFF.

•

For the vehicles with the keyless entry system, 
the delayed light-off time and the operation times 
of the keyless entry interior light answer back can 
be changed by the Customization Function 
(Refer to 

P.54A-17

).

INTERIOR LIGHT AUTOMATIC-SHUTOFF FUNCTION (THE INITIAL CONDITION: 30 
MINUTES)

When an interior light such as the dome light [all inte-
rior lights connecting to the dome light fuse (the front 
dome light, the rear dome light, and the ignition key 
cylinder illumination lights)] is lit, but either one of the 
conditions is met, the interior light is turned off auto-
matically for preventing the battery discharge caused 
by the unattended operation or the door-ajar.

• After 30 minutes with the interior light lit while the 

ignition switch is OFF, the light turns off automati-
cally.

• After 30 minutes with any door opened while the 

ignition switch is OFF, the light turns off automati-
cally.

• After the auto-turn OFF, the interior light returns 

to the illumination state when the doors are 
opened/closed, keyless entry transmitter switch 
is operated, or ignition switch is turned to ACC 
position. After returning, the light turns OFF after 
30 minutes, when the interior light auto turn off 
condition is met.

NOTE: The interior light automatic shut-off time can 
be adjusted by the Customization Function (Refer to 

P.54A-17

).

.

IGNITION KEY CYLINDER ILLUMINATION LIGHT CONTROL FUNCTION

The ETACS-ECU controls the ignition key cylinder 
illumination light as described below.

• With the ignition switch OFF, the light is illumi-

nated when the driver's door is opened, and it is 
turned off 30 seconds after the driver's door is 
closed. However, the light is turned off if the igni-
tion switch is turned ON or doors are locked

COMBINATION METER

COMBINATION METER

GENERAL INFORMATION

M2545500200428

The combination meter offers the following advan-
tages.

• Speedometer and tachometer are arranged sepa-

rately on the cylindrical shaped panel, achieving 
a sporty layout with which the zero position of 
needle indicator is arranged directly downward. 
Also, white is adopted for the needle color to 
improve visibility.

• New font style that offers good visibility and 

sporty feel has been adopted, and the color is 
made to bright white that offers a good contrast 
with the background matt black, securing excel-
lent visibility suitable for any driving condition 
encountered during daytime and nighttime.

• With the tachometer, the needle movement is 

made highly responsive to the engine speed.

• Multi information display has been adopted which 

displays various information, such as the S-AWC 
control level display, by the operation of multi 
information meter switch.

• By switching the display color of multi information 

display to red or yellow, the warning level is indi-
cated.

• The service reminder function has been adopted 

which notifies the users of the next periodic 
inspection timing using the driving distance and 
elapsed time.

• By operating the rheostat switch, the brightness 

of the meter and illumination can be adjusted in 
eight steps.

• The layout has been simplified by displaying what 

is required to meet the legislative requirements 
with the indicator, and by displaying other things 
with multi information display.

• A tone alarm is integrated in the combination 

meter so that the alarm contents or the operation 
status of switches can be checked with the tone 
alarm sound.

• To assure the LCD display responsiveness and 

brightness even under a low-temperature condi-
tion, the LCD heater has been adopted.
