Vehicles with the remote air conditioning system have the following risks that it is necessary to be aware of when performing repairs. Therefore, make sure to take care of the key (electrical transmitter) carefully so that the remote air conditioning system is not operated unexpectedly.

Risks 

The electrical fan and other items in the engine compartment may operate resulting in various hazards.

The wipers may operate if the wiper switch is in the on position when the remote air conditioning system is activated. If this occurs, there is the potential for damage to the glass, wipers or injury.

When the light control switch is in the tail, head or AUTO position, the headlights may turn on.

Short circuits may occur if electrical inspections are being performed when the remote air conditioning system is turned on, because the IG circuit is powered at this time.

CAUTION:

Failure to take proper care with the key (electrical transmitter) may cause the system to be accidentally operated. This can lead to an accident and damage to parts or a serious injury.

HINT:

1. Make sure to store the key (electrical transmitter) in a box with the switch side facing up, and place the box where it can be monitored so that no one cannot operate the remote A/C switch.
   
2. For operating condition of the remote air conditioning system, refer to System Description (Click here).
   

When performing repairs on vehicles with the solar ventilation system, turn the solar ventilation switch off.

CAUTION:

Depending on the environment around the vehicle, performing repairs with the solar ventilation switch on may cause the blower motor to operate unexpectedly, resulting in various hazards. This can lead to damage to parts or a serious injury.

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.
   

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.
   

If any metal particles enter intake system parts, this may damage the engine.

When removing and installing intake system parts, cover the openings of the removed parts and engine openings. Use adhesive tape or other suitable materials.

When installing intake system parts, check that no metal particles have entered the engine or installed parts.

Before removing a hose, check the clamp position so that it can be reinstalled in the same position.

Replace any deformed or dented clamps with new ones.

When reusing a hose, attach the clamp on the clamp track portion of the hose.

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.

Install an antenna as far away from the ECU and sensors of the vehicle electronic systems as possible.

Install an 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.

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.

Check that the antenna and feeder are correctly adjusted.

Do not install a high-powered mobile communication system.

When the headlights are illuminated, do not cover the headlights for 3 minutes or more.

Text in Illustration

BASIC OPERATION

1. This vehicle is equipped with an electronic shift lever system. This system electrically communicates the driver's intended shift state to the ECUs responsible for system control. The system also uses an electrically operated transaxle parking lock mechanism.
   

   HINT:

   The parking lock mechanism of the transaxle cannot be operated if the auxiliary battery is discharged or has been disconnected. There is no mechanical connection between the P position switch (transmission shift main switch), shift lever and the transaxle.

2. This system allows the driver to select the reverse (R), neutral (N), drive (D) and brake (B)* shift states using the shift lever, or select park (P) by pushing the P position switch (transmission shift main switch). Shift states are ECU controlled based on the actions of the driver and various conditions. Shift states can be verified using the shift position indicator in the combination meter or by using the intelligent tester.
   

   1. *: For enhanced engine braking.
      

VEHICLE CONDITIONS

1. Before activating inspection mode, turn the air conditioning off, start the hybrid system with park (P) selected, and check that the engine stops within several seconds after starting (engine warm up check).
   

2. Activate the appropriate inspection mode and inspect the vehicle (Click here).
   

   HINT:

   Different types of inspection mode are available. One is Maintenance Mode, and the other is Certification Mode. The following table indicates the mode appropriate for each test item.

   The shift state for each test is as follows:
   
   

   Test Item	Mode	Shift State
   1. Vehicle straight travelling test (side slip inspection)	Maintenance mode or normal mode	D
   2. Braking force test	Maintenance mode	N
   3. Speedometer test	Maintenance mode	D
   4. Exhaust gas test (idling)	Maintenance mode	P
   5. Headlight test	Maintenance mode or normal mode	P
