2) Vacuum System Related to 4WD
During 2WD mode, the vacuum
pressure from vacuum pump is
continuously transmitted to the
locking hub system.
This vacuum pressure pulls in the
locking hub actuator so that it will
not be engaged with the front end
hub gear.
22WD (applying vacuum pressure to hub
actuator) The vacuum pressure pulls in the
locking hub actuator so that it will not be
engaged with the front end hub gear.The vacuum pressure is released from the
hub actuator. At this time, the front hub end
gear is engaged.

(in 4WD
mode) Hub actuator (LH)Hub actuator (RH)
In 4WD mode, the TCCU blocks the transferring of
vacuum pressure from vacuum pump to locking hub
by supplying the power to solenoid valve.

2) 4H Mode (4 Wheel Drive - High Speed)
Power Flow ▶
The driving force is pass through 4WD High magnetic clutch in transfer case and is distributed on
front wheels and rear wheels (50;50).

3) 4L Mode (4 Wheel Drive - Low Speed)
Power Flow ▶
The gear ratio is reduced to 2.48;1 while passing through 4WD Low range and planetary gear set in
transfer case and the driving force is distributed on front wheels and rear wheels(50;50).

Rear suspension
1. SUSPENSION
The suspension is the device to connect the axle and vehicle. It absorbs the vibrations and impacts from
road surface, which enhances the comforts, driving force, braking force and drivability.
