3. ELECTRONIC CONTROL
Text in Illustration
NOTICE:
* Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.
* After the ignition switch is turned off, the navigation receiver assembly (for Navigation Receiver Type) or radio and display receiver assembly (for Radio and Display Type with Intuitive Parking Assist System) records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 60 seconds before disconnecting the cable from the negative (-) battery terminal.
(a) DISCONNECTING AND RECONNECTING NEGATIVE BATTERY CABLE
(1) Before performing work on electronic components, disconnect the cable from the negative (-) battery terminal to prevent damage to the electrical system or components.
(2) When disconnecting the cable, turn the ignition switch and headlight switch off and loosen the cable nut completely. Perform these operations without twisting or prying the cable. Then disconnect the cable.
(3) Clock settings, radio settings, audio system memory, DTCs and other data will be cleared when the cable is disconnected from the negative (-) battery terminal. Write down any necessary data before disconnecting the cable.
(b) HANDLING OF ELECTRONIC PARTS
Text in Illustration
(1) Do not open the cover or case of the ECU unless absolutely necessary. If the IC terminals are touched, the IC may be rendered inoperative by static electricity.
(2) Do not pull on the wires when disconnecting electronic connectors. Pull on the connector itself.
(3) Do not drop electronic components, such as sensors or relays. If they are dropped on a hard surface, they should be replaced.
(4) When cleaning the engine components with steam, protect the electronic components, air filter and emission-related components from water.
(5) Never use an impact wrench to remove or install temperature switches or temperature sensors.
(6) When measuring the resistance between terminals of a wire connector, insert the tester probe carefully to prevent the terminals from bending.
4. REMOVAL AND INSTALLATION OF FUEL CONTROL PARTS
(a) PLACE FOR REMOVING AND INSTALLING FUEL SYSTEM PARTS
(1) Work in a location with good air ventilation that does not have welders, grinders, drills, electric motors, stoves, or any other ignition sources nearby.
(2) Never work in a pit or near a pit as fuel vapors will collect there.
(b) REMOVING AND INSTALLING FUEL SYSTEM PARTS
(1) Prepare a fire extinguisher before starting work.
(2) To prevent static electricity, install a ground wire between the fuel changer and vehicle, and do not spray the surrounding area with water. Be careful when performing work in this area, as the floor surface will become slippery. Do not clean up gasoline spills with water, as this may cause the gasoline to spread, and possibly create a fire hazard.
(3) Avoid using electric motors, work lights and other electric equipment that can cause sparks or high temperatures.
(4) Avoid using iron hammers as they may create sparks.
(5) Dispose of fuel-contaminated cloth separately using a fire resistant container.
5. REMOVAL AND INSTALLATION OF ENGINE INTAKE PARTS
(a) If any metal particles enter intake system parts, this may damage the engine.
(b) When removing and installing intake system parts, cover the openings of the removed parts and engine openings. Use adhesive tape or other suitable materials.
(c) When installing intake system parts, check that no metal particles have entered the engine or installed parts.
6. HANDLING OF HOSE CLAMPS
Text in Illustration
(a) Before removing a hose, check the clamp position so that it can be reinstalled in the same position.
(b) Replace any deformed or dented clamps with new ones.
(c) When reusing a hose, attach the clamp on the clamp track portion of the hose.
(d) For a spring type clamp, it may be necessary to spread the tabs slightly after installation by pushing them in the direction of the arrows as shown in the illustration.
7. FOR VEHICLES EQUIPPED WITH MOBILE COMMUNICATION SYSTEMS
(a) Install the antenna as far away from the ECU and sensors of the vehicle electronic systems as possible.
(b) Install the antenna and feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the vehicle electronic systems. For details about ECU and sensor locations, refer to the section on the applicable components.
(c) Keep the antenna and feeder separate from other wiring as much as possible. This will prevent signals sent from the communication equipment from affecting vehicle equipment and vice versa.
(d) Check that the antenna and feeder are correctly adjusted.
(e) Do not install a high-powered mobile communication system.
8. HEADLIGHT INSPECTION OR MAINTENANCE
(a) When the headlight dimmer switch assembly is set to head, do not touch the discharge headlight high-voltage socket area.
NOTICE:
When performing inspection or maintenance, the discharge headlight precautions must be followed.
(b) When the headlights are illuminated, do not cover the headlights for 3 minutes or more.

NOTICE:
As the headlight's outer lens is made of resin, the resulting heat created when covering the headlight for an extended period of time may deform the headlight.
9. FOR VEHICLES EQUIPPED WITH TRACTION CONTROL (TR(A)C) AND VEHICLE STABILITY CONTROL (VSC) SYSTEMS
When testing with a 2-wheel drum tester such as a speedometer tester, a combination speedometer and brake tester, or a chassis dynamometer, or when jacking up the front wheels and turning the wheels, perform the following procedure to enter inspection mode and disable the TR(A)C and VSC systems Service Precautions.
HINT
* The vehicle may slip unexpectedly out of the dynamometer because of TR(A)C and VSC operation.
* Pressing the VSC OFF switch (for vehicles with a VSC OFF switch) does not disable TR(A)C and VSC operation completely.
NOTICE:
* Make sure that the VSC warning light is blinking.
* Secure the vehicle with chains for safety.
10. PRECAUTIONS FOR TOWING FRONT WHEEL DRIVE VEHICLES
(a) Use one of the following methods to tow the vehicle.
(b) If the vehicle has trouble with the chassis or drivetrain, use method 1 (flatbed truck).
NOTICE:
Do not use any towing method other than those shown above.
(c) If a tow truck is not available, in an emergency the vehicle may be temporarily towed using a cable or chain secured to the emergency towing eyelet(s). This should only be attempted on hard surfaced roads for distances of less than 80 km, and at speeds below 30 km/h (19 mph).
A driver must be in the vehicle to steer and operate the brakes. The vehicle's wheels, drivetrain, axles, steering and brakes must be in good condition.
NOTICE:
If the towing speed or distance exceeds the above limits, or the vehicle is towed in a backward direction with the front wheels on the ground, the transaxle may be damaged.
(1) Emergency towing procedure
1 Turn the ignition switch ON.
2 Depress the brake pedal and move the shift lever to N.
3 Release the parking brake.
4 Release the brake pedal slowly.
NOTICE:
* Use extreme caution when towing the vehicle. Avoid sudden starts or erratic driving maneuvers which place excessive stress on the emergency towing eyelet and the cables or chains.
* Do not turn off the ignition switch. Turning off the ignition switch may result in engagement of the steering lock, resulting in a hazardous situation or accident.
(d) The towing methods shown below are dangerous and can damage the vehicle, so do not use them.
(1) Do not tow the vehicle facing rearward with the front wheels on the ground.
NOTICE:
* If the vehicle is towed facing rearward with the front wheels on the ground, the drivetrain may overheat and be damaged.
* In addition, if the vehicle is equipped with the VSC system, the system may apply the brakes to the rotating wheels.
(2) Do not use a sling-type towing method either from the front or rear.
NOTICE:
If a sling-type tow truck is used, damage may occur to the vehicle body.
11. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline or gasoline vapors flow into the converter, it may cause converter overheating and create a fire hazard. To prevent this, observe the following precautions:
(a) Use only unleaded gasoline.
(b) Avoid performing unnecessary spark tests.
(1) Perform a spark test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine unless instructed.
(c) Avoid a prolonged engine compression measurement. Engine compression measurements must be performed as rapidly as possible.
(d) Do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the converter.
12. EXPRESSIONS OF IGNITION SWITCH
(a) The type of ignition switch used on this model differs according to the specifications of the vehicle.
The expressions listed in the table below are used in this section.
