*1: ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to the ECM through CAN communication line.
SYSTEM DESCRIPTION
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve.
The ECM receives signals such as crankshaft position, camshaft position, engine speed, engine oil temperature and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing (IVT) control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in highspeed range.

Steering wheel
Tilt operation
Push the lock lever 1 down and adjust the
steering wheel up or down 2 to the desired
position.
Pull the lock lever 1 up to lock the steering
wheel in place.
WARNING
Do not adjust the steering wheel while
driving. You could lose control of your
vehicle and cause an accid ...
Recommended fluids/lubricants and capacities
The following are approximate capacities. The actual refill capacities may
be a little different. When refilling, follow the procedure
described in the "Do-it-yourself" section to determine the proper refill
capacity.
