PRECAUTIONS FOR VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE
• Intelligent Cruise Control is functionally limited. This never support careless driving and low visibility (rain,fog, etc.). Drive the vehicle safely. Keep a safe di stance between vehicles by decreasing the vehicle speed
according to the driving condition etc.
• Intelligent Cruise Control never stop the vehicle autom atically. Intelligent Cruise Control is automatically
released, and the buzzer sounds if any vehicle ahead is not detected when the vehicle speed is approxi-
mately 35 km (21.5 MPH) or less.
• Use this system when the vehicle speed does not extr emely change. This system may not properly function
when any vehicle cuts in, or when the vehicle ahead s uddenly applies the brake. Then, the warning (buzzer
and indication) activates.
• Never use Intelligent Cruise Control in the following conditions.
- A well-trafficed road, and a tight turn. It may cause any accident because the dr iving does not fit to the road condition.
- A slippery road (e.g., freezing, or snowy road) The vehicle may lose the control by wheelspin.
- The vehicle drives in bad whet her (rain, fog, snow etc.).
The distance from the vehicle ahead is not detected pr ecisely if the whether condition is bad. Intelligent
Cruise Control is released automatically if the wiper activates in low or high speed.
- The vehicle receives bright light (sunshine etc.). The distance from the vehicle ahead is not detected pr ecisely if bright light enters in the vehicle.
- Raindrop or snow is on the sensor.
The distance from the vehicle ahead is not detected prec isely if raindrop or snow attaches on the sensor.
- A steep downhill The setting vehicle speed may exceed if Intelligent Cruise Control does not detect the vehicle ahead. The
brake may heat up in the vehicle- to-vehicle distance control mode.
- A repeated uphill and downhill Intelligent Cruise Control may not detect the vehicl e ahead precisely. An accident may occur by tailgating.
- Maintaining proper vehicle distance is difficult due to frequent acceleration/deceleration. It may cause any accident because the driving does not fit to the road condition if keeping a proper vehicle-
to-vehicle distance is difficult.
- When entering in the highway interchange (swerving off the main line),
Unexpected accident may cause if the vehicle ahead drives slower
than the preset vehicle speed. T he vehicle-to-vehicle distance con-
trol mode accelerates automatically because the vehicle ahead is
not detected on the lane if the own vehicle or the vehicle ahead
changes the lane.
• Intelligent Cruise Control does not activate to the parking vehicles, and vehicles driving extremely slow er than the own vehicle. Never
hit the vehicle stopping at a tollgate, or the tail end of traffic jam.
• Intelligent Cruise Control does not activate to the vehicle edging way, and non-vehicle objects (passengers etc.).
• This function detects the reflector of the vehicle ahead. Intelligent Cruise Control may not detect the vehicle
ahead, and keep a proper vehicle-to-vehicle distance in t he following conditions. Drive the vehicle according
to the driving condition.
- The vehicle ahead installs the reflector higher (trailer etc.).
- The rear of the vehicle ahead is extremely dirt.
- The vehicle ahead or vehicle on other lanes splashes water or snow on the road.
- The vehicle ahead provides dark exhaust gas. Smoke blocks the visibility.
- The vehicle ahead attaches film on the reflector. The v ehicle ahead does not install the reflector. The reflec-
tor is broken.
- Extremely heavy load is on the rear seat or in the cargo area.
- The vehicle drives on a repeated uphill and downhill

• The sensor detection distance is limited if the vehicle-to-vehicle distance is close. The vehicle distance may not maintain properly
because the motorcycle (A) driving on the lane edge is not
detected or detecting the vehicle ahead (cutting in the own vehicle)
delays.
• The sensor dirt is detected automat ically. But it is not perfect. Dirt
is not judged despite the sensor is dirt. Dirt is not detected if snow
or ice is on the sensor.
Keeping the vehicle-to-vehicle distance is difficult. Drive the vehi-
cle safely. Always clean the sensor.
Intelligent Cruise Control is released automatically if dirt is
detected.
• The vehicle ahead may not be detected temporarily, the vehicle or object on the neighboring lane may be
detected or the warning buzzer may sound according to the road shape (curve and narrow road) and the
own vehicle condition (steering, driving lane position, accident , malfunction etc.).
The vehicle ahead is not detected temporarily. The vehicle approaches too close.
PRECAUTIONS FOR CONVENTIONAL (F IXED SPEED) CRUISE CONTROL MODE
• Conventional cruise control mode does neither control the brake nor activate the warning.
Drive the vehicle safely. Keep a safe distance between vehicles by decreasing the vehicle speed according
to the driving condition etc.
• Never use the conventional cruise control mode in the following conditions.
- A well-trafficed road, and a tight turn. It may cause any accident because the driving does not fit to the road condition.
- A slippery road (e.g., freezing, or snowy road) The vehicle may lose the control by wheelspin.
- A steep downhill The engine brake does not activate effectively on a steep downhill. The preset vehicle speed may exceed.

*2: This signal is sent to the ECM through CAN communication line.
*3: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is
determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). T he amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from both the crankshaft position sensor and the mass air
flow sensor.
VARIOUS FUEL INJECTION I NCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compensated to improve engine performance under various operat-
ing conditions as listed below.
• When starting the engine
• During acceleration
• Hot-engine operation
• When selector lever is changed from N to D
• High-load, high-speed operation
• During deceleration
• During high engine speed operation

ON BOARD DIAGNOSTIC (OBD) SYSTEM
tified codes can be identified by using the CONSULT-II
I or GST. A DTC will be used as an example for how to
read a code.
A particular trouble code can be identified by the number of four-digit numeral flashes. The “zero” is indicated
by the number of ten flashes. The “A” is indicated by the number of eleven flash.The length of time the
1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-second) - OFF (0.6-second)
cycle.
The 100th-digit numeral and lower digit numerals cons ist of a 0.3-second ON and 0.3-second OFF cycle.
A change from one digit numeral to another occurs at an inte rval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occu rs at an interval of 1.8-second OFF.
In this way, all the detected malfunctions are classi fied by their DTC numbers. The DTC 0000 refers to no mal-
function. (See EC-462, "
DTC Index")
How to Erase Diagnostic Test Mode II (Self-diagnostic Results)
The DTC can be erased from the back up memory in the ECM by depressing accelerator pedal. Refer to "How
to Erase Diagnostic Test Mode II (Self-diagnostic Results)".
•If the battery is disconnected, the DTC will be lost from the backup memory within 24 hours.
• Be careful not to erase the stored memo ry before starting trouble diagnoses.

RELATIONSHIP BETWEEN MIL, 1ST TRIP DTC, DTC, AND DETECTABLE ITEMS
• When a malfunction is detected for the first time, the 1st trip DTC and the 1st trip freeze frame data are
stored in the ECM memory.
• When the same malfunction is detected in two consec utive trips, the DTC and the freeze frame data are
stored in the ECM memory, and the MIL will come on. For details, refer to EC-41, "
Two Trip Detection Logic".
• The MIL will go off after the vehicle is driven 3 time s (driving pattern B) with no malfunction. The drive is
counted only when the recorded driving pattern is met (as stored in the ECM). If another malfunction occurs
while counting, the counter will reset.
• The DTC and the freeze frame data will be stored until the vehicle is driven 40 times (driving pattern A) with-
out the same malfunction recurring (except for Misfire and Fuel Injection System). For Misfire and Fuel Injec-
tion System, the DTC and freeze frame data will be stored until the vehicle is driven 80 times (driving pattern
