BLEEDING
Caution
Specified brake fluid: DOT3 or DOT4
1. Always use the specified brake fluid. Avoid using
a mixture of the specified brake fluid and other fluid.
2. Maintain the fluid reservoir level between the MIN
and MAX marks during the air bleeding.
3. Do not depress the brake pedal hard during the air
bleeding (normal air bleeding) to prevent the pump
motor from operating frequently.
4. After the air bleeding, check that the brake dragging
does not become stronger.
5. If the pedal is depressed with the reservoir cap
removed, the brake fluid may overflow. Do not depress
the brake pedal while the fluid is being added.
NORMAL AIR BLEEDING
After the front brake or the rear brake is removed and installed,
some fluid may remain in the hydraulic brake booster (HBB)
reservoir. In this case, bleed air from the brake caliper.
HBB SYSTEM AIR BLEEDING
If all the brake fluid inside the reservoir is drained due to
the removal and installation of the HBB, bleed air as follows:
Air bleeding from front brake system
1. Turn the ignition switch to the LOCK (OFF) position. Bleed
air from the front brake calipers (right and left) by pumping
the brake pedal.
Pump motor operation
2. Turn the ignition switch ON, and operate the pump motor.
If the pump motor is running free, supply the brake fluid
into the pump motor by depressing the brake pedal three
or four times.
Air bleeding from accumulator system
3. After the pump motor stopped, depress the brake pedal
three or four times with the ignition switch ON. Then
observe the brake fluid in the reservoir. If the brake fluid
looks whitish, wait for a few minutes until it becomes
clear.
4. Repeat step 3 until the brake fluid becomes clear.

SUNROOF MOTOR ASSEMBLY INSTALLATION

1. Install the roof lid glass assembly and the sunroof motor
assembly with the sunroof motor assembly in the
fully-closed position.
2. Connect the sunroof motor assembly harness connector
and the sunroof switch harness connector to the vehicle
wiring harness connector.
3. Operate the sunroof and check that it operates correctly.
INSTALLATION>
1. Install the roof lid glass assembly and the sunroof motor
assembly with the sunroof motor assembly in the
fully-closed position.
2. Connect the sunroof motor assembly harness connector
and the sunroof switch harness connector to the vehicle
wiring harness connector.
3. Operate the sunroof switch to slide the roof lid glass
to the fully-open position, and then tilt it up in steps of
30 mm to the fully-open position and then keep pressing
the switch for 3 seconds or more.
4. Operate the sunroof switch (CLOSE) using the one-touch
function to slide the roof lid glass to the fully-closed
position.
5. Operate the sunroof switch (OPEN) using the one-touch
function to slide the roof lid glass to the fully-open position.
6. Operate the sunroof switch (CLOSE) using the one-touch
function to slide the roof lid glass to the fully-closed
position.
7. Press the tilt - up switch to operate the sunroof and check
that learning is complete.
NOTE
(1) During initialisation (learning mode), use only the
CLOSE/DOWN switch to move the roof lid glass from
the fully-closed position to the fully tilted open position.
During initialisation, the TILT UP switch will not work
when pressed. Furthermore, the sunroof-ECU will stop
running in learning mode as soon as the roof lid glass
is tilted up.
(2) When the clamping prevention mechanism is
cancelled, the operation is the same as when the
roof lid glass operates 30 mm at a time.

OPERATION
BUZZER
Light Reminder Warning Buzzer Function
When the driver’s door is opened with lighting switch
in the ON (tail lamp switch or headlamp switch)
position and ignition switch in the LOCK (OFF) or
ACC position, the buzzer will sound continuously to
remind the driver that the lamps (tail lamps or
headlamps) are ON.
This function does not work if the lighting switched
off through the headlamp automatic shutdownfunction. In addition, the ignition key reminder
warning buzzer function has a priority over this
function.
Center Display Operation Annunciation
Function
On vehicles with center display, the buzzer (peeps)
sounds when the operation switch of the audio
and navigation system is pressed.
CENTRAL DOOR LOCKING SYSTEM
Central Door Locking System Operation
When the lock switch is turned ON after the unlock
switch on the driver’s door lock actuator switch
is OFF, the ETACS-ECU gives a lock output for
0.5 second. When the unlock switch is turned ON
after the lock switch on the driver’s door lock
actuator switch is OFF, the ETACS-ECU gives an
unlock output for 0.5 second.
When the front passenger’s door key or back door
key is operated, the ETACS-ECU gives a lock or
unlock output for 0.5 second.Forgotten Key Prevention Function
If, with the key reminder switch OFF and the driver’s
door switch ON, the driver’s door lock switch is
turned ON after the door unlock switch in the front
door lock actuator is turned OFF, the ETACS-ECU
waits 0.3 second then give an unlock relay output
for 0.5 second, there by preventing the doors from
being locked. This operation prevents the ignition
key from being locked inside the vehicle. This
function takes precedence over the central door
locking control function.
