SEAT BELT – SEAT BELT WARNING SYSTEMSB–3
SB
SYSTEM DESCRIPTION
1. DRIVER SEAT BELT WARNING LIGHT
(a) When the driver seat belt is not fastened with the
ignition switch ON, the driver seat belt warning light
on the combination meter comes on to inform the
driver. The center airbag sensor detects the driver
seat belt status and sends signals to the
combination meter through the CAN bus line.
2. PASSENGER SEAT BELT WARNING LIGHT
(a) for Automatic air conditioning system:
When the passenger seat belt is not fastened with
the ignition switch ON and the passenger seat
occupied, check that the passenger seat belt
warning light on the heater control panel display
blinks. The combination meter detects the
passenger seat belt status and whether the
passenger seat is occupied.
(b) for Manual air conditioning system:
When the passenger seat belt is not fastened with
the ignition switch ON and the passenger seat
occupied, check that the passenger seat belt
warning light on the clock panel blinks. The
combination meter detects the passenger seat belt
status and whether the passenger seat is occupied.

CRUISE CONTROL – CRUISE CONTROL SYSTEMCC–5
CC
SYSTEM DESCRIPTION
1. CRUISE CONTROL SYSTEM
This system is controlled by the ECM, and is activated by
the throttle position sensor and motor. The ECM controls
the following functions: ON-OFF, SET / COAST,
RESUME / ACCEL, CANCEL, vehicle speed operation,
motor output control, and overdrive control.
• The ECM compares the driving vehicle speed from
the combination meter with the stored vehicle speed
set through the cruise control switch. The ECM
controls the throttle valve motor of the throttle body to
open the valve when the driving speed is less than the
stored speed.
• The ECM receives signals such as ON-OFF, SET /
COAST, RESUME / ACCEL, and CANCEL from the
cruise control switch.
• The ECM illuminates the combination meter CRUISE
main indicator light when it receives the cruise control
switch ON signal.
• The ECM cancels the cruise control system when the
brake pedal is depressed and the ECM receives the
stop light switch signal.
• The ECM cancels the cruise control system when the
shift lever is moved from D or 3 to a position other
than D or 3, and the ECM receives the PNP switch
signal.
2. LIMIT CONTROL
(a) Low speed limit
The lowest possible limit of the speed setting range
is set at approximately 40 km/h (25 mph). The
cruise control system cannot be set when the
driving vehicle speed is below the low speed limit.
Cruise control operation will be automatically
canceled when the vehicle speed decreases below
the low speed limit 40 km/h (25 mph) while the
cruise control is in operation.
(b) High speed limit
The highest possible limit of the speed setting range
is set at approximately 200 km/h (125 mph). The
cruise control system cannot be set when the
driving vehicle speed is over the high speed limit.
Also, +/RES cannot be used to increase speed
beyond the high speed limit.

3. OPERATION OF CRUISE CONTROL
The cruise control switch operates 7 functions: SET,
COAST, TAP-DOWN, RESUME, ACCELERATION
(ACCEL), TAP-UP, and CANCEL. The SET, TAP-DOWN
and COAST functions, and the RESUME, TAP-UP and
ACCEL functions are operated with the same switch.
The cruise control switch is an automatic return type
switch which turns on only when pressed in each arrow
direction and turns off when released.
(a) SET CONTROL
Vehicle speed is stored and constant speed control
is maintained when pushing the switch to -/SET
while driving with the cruise control switch ON (the
CRUISE main indicator light is illuminated), and the
vehicle speed is within the set speed range
(between the low and high speed limits).
(b) COAST CONTROL
The ECM changes the cruise control demanding
throttle opening angle to 0
and decelerates the
vehicle when -/SET on the cruise control switch is
pressed and held while the cruise control system is
operating. When the cruise control switch is
released from -/SET, the vehicle speed is stored and
constant speed control is maintained.
HINT:
• The throttle valve is not fully closed due to idle
speed control, etc.
•w/ VSC:
The brake is also used to decelerate the vehicle.
(c) TAP-DOWN CONTROL
When tapping down the cruise control switch to -/
SET (for approximately 0.5 seconds) while the
cruise control system is in operation, the stored
vehicle speed decreases each time by
approximately 1.6 km/h (1.0 mph). When the cruise
control switch is released from -/SET and the
difference between the driving and stored vehicle
speed is less than 5 km/h (3 mph), the vehicle
speed is stored and constant speed control is
maintained.
(d) ACCEL CONTROL
The throttle valve motor of the throttle position
sensor and motor is instructed by the ECM to open
the throttle valve when +/RES on the cruise control
switch is pressed and held while the cruise control
system is operating. When the cruise control switch
is released from +/RES, the vehicle speed is stored
and constant speed is maintained.

(b) If the test value is between the minimum and
maximum test limits, the component is functioning
normally. If not, the component is malfunctioning.
The test value is usually not near the test limits. If
the test value is near the test limits, the component
is likely to malfunction in the near future.
HINT:
The monitor result might on rare occasions be
PASS even if the malfunction indicator lamp (MIL) is
illuminated. This indicates the system malfunctioned
on a previous driving cycle. This might be caused by
an intermittent problem.
