>> GO TO 7.

CHECK FOR CANCELLATION OF VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE

Check that the vehicle-to-vehicle distance control mode is canceled when performing the following operations.
• When the brake pedal is depressed after the system is turned ON.
• When the selector lever is shifted to the “N” range.
• When the MAIN switch is turned OFF.
• When CANCEL switch is operated.

CHECK FOR RESTORING SPEED THAT IS SET BY VEHICLE-TO-VEHICLE DISTANCE CONTROL

MODE BEFORE CANCELLATION

Check that the vehicle restores the previous speed kept before the system deactivation when performing the
following operations.
• Cancel the system by depressing the brake pedal. Then check if the speed before cancellation is restored

when pushing up RESUME/ACCELERATE switch with 40 km/h (25 MPH) or above.

• Shift the selector lever to the “N” range to cancel the system. Then shift the selector lever back to the “D”

range. Check that the vehicle restores the previous speed kept before the system deactivation when push-
ing up the RESUME/ACCELERATE switch while the vehicle speed is 40 km/h (25 MPH) or more.

• Press the CANCEL switch to cancel the system. Then check that the vehicle restores the previous speed

kept before the system deactivation when pushing up the RESUME/ACCELERATE switch while the vehicle
speed is 40 km/h (25 MPH) or more.

ACTION TEST : Special Repair Requirement (Conventional (Fixed Speed) Cruise
Control Mode)

INFOID:0000000003130027

NOTE:
The running speed can be set between 40 km/h (25 MPH) and 144 km/h (90 MPH).

CAUTION:

Never set the cruise speed exceeding the posted speed limit.

CHECK FOR MAIN SWITCH

Start engine.

Press the MAIN switch (1) for more than 1.5 seconds.

Check that the ICC system display in the combination meter
indicates that the conventional (fixed speed) cruise control mode
is ready for activation.

Press the MAIN switch, and check that the ICC system display
turns off when the ICC system is deactivated.

Check that the ICC system display turns off after starting the
engine again.

>> GO TO 2.

CHECK FOR RESUME/ACCELERATE, SET/COAST, CANCEL SWITCHES

Check if RESUME/ACCELERATE, SET/COAST, CANCEL switches are operated smoothly.

Check if switches come up as hand is released from the switches.

>> GO TO 3.

SET CHECKING

Start engine.

[INTELLIGENT CRUISE CONTROL]

INSPECTION AND ADJUSTMENT

Press the MAIN switch for more than 1.5 seconds.

Drive the vehicle at 40 km/h (25 MPH) or more.

Push down the SET/COAST switch.

Confirm that the desired speed is set as hand is released from the SET/COAST switch.

NOTE:
• The set vehicle speed is not displayed on the ICC system display.
• The SET indicator in the ICC system display illuminates.

>> GO TO 4.

CHECK FOR INCREASE OF CRUISING SPEED

Set the conventional (fixed speed) cruise control mode at desired speed.

Check if the set speed increases by 1.6 km/h (1 MPH) as RESUME/ACCELERATE switch is pushed up.

NOTE:
• If the RESUME/ACCELERATE switch is kept pushing up during cruise control driving, the vehicle speed

increases until the switch is released.

• The maximum set speed is 144 km/h (90 MPH).

CAUTION:

Never set the cruise speed exceeding the posted speed limit.

>> GO TO 5.

CHECK FOR DECREASE OF CRUISING SPEED

Set the conventional (fixed speed) cruise control mode at desired speed.

Check if the set speed decreases by 1.6 km/h (1 MPH) as SET/COAST switch is pushed down.

NOTE:
• Conventional (fixed speed) cruise control mode is automatically cancelled when the driving speed lowers to

32 km/h (20 MPH).

• The lowest set speed is 40 km/h (25 MPH).

>> GO TO 6.

CHECK FOR CANCELLATION OF CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE

Check that the CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE is canceled when performing
the following operations.
• When the brake pedal is depressed after the system is turned ON.
• When the selector lever is shifted to the “N” range.
• When the MAIN switch is turned OFF.
• When CANCEL switch is operated.

>> GO TO 7.

CHECK FOR RESTORING SPEED THAT IS SET BY CONVENTIONAL (FIXED SPEED) CRUISE CON-

TROL MODE BEFORE CANCELLATION

when pushing up RESUME/ACCELERATE switch with 40 km/h (25 MPH) or above.

• Shift the selector lever to the “N” range to cancel the system. Then shift the selector lever back to the “D”

range. Check that the vehicle restores the previous speed kept before the system deactivation when push-
ing up the RESUME/ACCELERATE switch while the vehicle speed is 40 km/h (25 MPH) or more.

• Press the CANCEL switch to cancel the system. Then check that the vehicle restores the previous speed

kept before the system deactivation when pushing up the RESUME/ACCELERATE switch while the vehicle
speed is 40 km/h (25 MPH) or more.

FUNCTION DIAGNOSIS

INTELLIGENT CRUISE CONTROL SYSTEM

System Diagram

INFOID:0000000003130028

System Description

INFOID:0000000003130029

• The Intelligent Cruise Control (ICC) system automatically maintains a selected distance from the vehicle

ahead according to that vehicle's speed, or the set speed, if the road ahead is clear.

• The ICC function has two cruise control modes and brake assist (with preview function).
• To activate or deactivate the ICC system and set the vehicle speed and vehicle-to-vehicle distance, use the

ICC steering switch.

• The operation status of the ICC system is indicated on the ICC system display of the combination meter.

VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE

• Vehicle-to-vehicle distance control mode, the driver can maintain the same speed as other vehicles without

the constant need to adjust the set speed as the driver would with a normal cruise control system.

• The system is intended to enhance the operation of the vehicle when following the vehicle traveling in the

same lane and direction.

• If the ICC sensor integrated unit detects a slower moving vehicle ahead, the system will reduce speed so

that the vehicle ahead can be followed at the selected distance.

• The system automatically controls the throttle and applies the brakes (up to 25% of vehicle braking power) if

necessary.

• The detection range of the sensor is approximately 390 ft (120 m) ahead.
• Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.

CONVENTIONAL (FIXED SPEED) CRUISE CONTROL MODE

• Conventional (fixed speed) cruise control mode is cruising at preset speeds.
• Refer to Owner's Manual for Intelligent Cruise Control System operating instructions.

BRAKE ASSIST (WITH PREVIEW FUNCTION)

• When the force applied to brake pedal exceeds a certain level, the Brake Assist is activated and generates a

greater braking force than that of a conventional brake booster even with light pedal force.

< FUNCTION DIAGNOSIS >

[INTELLIGENT CRUISE CONTROL]

INTELLIGENT CRUISE CONTROL SYSTEM

• When the Preview Function identifies the need to apply the sudden brake by sensing the vehicle ahead in

the same lane and the distance and relative speed from it, it applies the brake pre-pressure before driver
depresses the brake pedal and improves brake response by reducing its free play.

• Refer to Owner's Manual for BRAKE ASSIST (WITH PREVIEW FUNCTION) operating instructions.

ICC STEERING SWITCH

ICC system is operated by MAIN switch and four control switches, all mounted on the steering wheel.

NOTE:
The on board self-diagnosis function of the ICC system can be started with the RESUME/ACCELERATE
switch and SET/COAST switch. Refer to
