INTRODUCTION: REPAIR INSTRUCTION: PRECAUTION (Continued..)
16. ELECTRONIC SHIFT LEVER SYSTEM
(a) 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 Techstream.
* *: For enhanced engine braking.
17. WHEN INSPECTING VEHICLES
NOTICE:
When the vehicle is run in inspection mode for an operation such as a speedometer test, a DTC may be set. Therefore, if the warning light comes on, after canceling inspection mode, check for DTCs using the Techstream and clear the DTCs.
(a) VEHICLE CONDITIONS
(1) Warm up the engine with the air conditioning off and park (P) selected.
(2) Activate the appropriate inspection mode and inspect the vehicle Component Tests and General Diagnostics.
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:
(3) Cancel inspection mode immediately after completion of inspection.
NOTICE:
Driving the vehicle without canceling inspection mode may damage the transaxle.
(b) WHEN USING A BRAKE TESTER
CAUTION:
Be sure to perform the test in maintenance mode.
NOTICE:
* A high-speed type brake tester cannot be used.
* Vehicle speed should be less than 0.5 km/h (0.3 mph).
* Follow all usage and safety procedures in the operator's manual for the brake tester.
(1) Place the wheels to be tested (front or rear) onto the rollers.
(2) Start the hybrid system to allow normal brake booster operation.
(3) Move the shift lever to N and confirm that neutral (N) has been selected.
(4) Operate the brakes to perform the test.
(c) WHEN USING A SPEEDOMETER TESTER
CAUTION:
Be sure to perform the test in maintenance mode.
NOTICE:
Do not perform rapid starting or quick acceleration on a speedometer tester. If rapid starting or quick acceleration is performed on a speedometer tester, damage may occur to the transaxle.
(1) Depress the accelerator pedal slowly and gradually accelerate the vehicle. Make a measurement.
(2) After the measurement, use the brakes to gradually decelerate the vehicle.
(d) WHEN USING A CHASSIS DYNAMOMETER
(1) Always set an appropriate load before starting the test.
NOTICE:
Sudden acceleration or deceleration of the vehicle on a chassis dynamometer under minimal load may damage the transaxle.
(e) WHEN USING AN ON-VEHICLE BALANCER
(1) Raise the vehicle until all 4 wheels are off the ground.
(2) Support the vehicle with safety stands at an appropriate height. Make sure that the vehicle does not lean in any direction, and that the tires are completely clear of the floor.
(3) Place the vibration pick-up unit into position for the wheel to be measured*1.
HINT
*1: Different on-vehicle wheel balancers have different requirements for mounting the vibration pick-up unit(s). Refer to the operator's manual for the wheel balancer to confirm requirements for use.
(4) Release the parking brake.
(5) Check that no dragging force exists when turning each wheel by hand.
(6) Put the wheel balancer in position.
(7) Wheel balance measurement should be done by using both the engine and the wheel balancer drive roller to spin the wheels.
NOTICE:
* Be sure to perform the test in maintenance mode.
* Start the hybrid system and then increase the vehicle speed gradually with drive (D) selected.
* Do not accelerate or decelerate suddenly.
* Deceleration should be done by braking gradually.
* Make sure that no one is standing in-line with the spinning wheels.
* Measurement should be done quickly.
* Confirm that the vehicle is securely immobilized.
* Follow all usage and safety procedures in the operator's manual for the wheel balancer.
18. PRECAUTIONS FOR TOWING 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 short distances 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 power switch on (IG).
2 Depress the brake pedal, move the shift lever to N and confirm that neutral (N) has been selected.
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.
* If the hybrid system is off, the power assist for the brakes and steering will not function, making steering and braking more difficult.
* Do not turn off the power switch. Turning off the power switch may result in engagement of the parking lock, resulting in a hazardous situation or accident.
HINT
* Neutral (N) cannot be selected if the auxiliary battery is disconnected.
* There is a possibility that neutral (N) cannot be selected when parts related to the transmission control ECU have a malfunction.
(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.
19. 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.
