GENERAL INFORMATION

M2370000101478

The hydraulic power steering system has been 
adopted.
The steering system offers the following features.

• The support method of the steering gear to the 

crossmember is realized by the left and right 
bushings with inner cylinders for improved steer-
ing feeling.

• The AWC switch has been installed on the steer-

ing wheel top surface for improved convenience.

• For some models, the steering wheel audio 

remote control switch and steering wheel voice 
control switch have been established for 
improved convenience.

• The variable flow pump, which reduces the 

engine loss by controlling the flow amount neces-
sary for driving straight ahead or cornering, has 
been adopted.

• The flexible tube length in the high pressure hose 

has been optimized for reducing the pump noise.

• The reservoir tank already adopted for Outlander 

has been adopted, and the baffle plate inside the 
cap has been improved to prevent oil leakage 
under the high load condition.

STEERING WHEEL

M2370001001087

The steering wheel is designed to improve operabil-
ity and safety, and has the following features.

• The genuine leather 3-spoke type has been 

adopted.

• The AWC switch has been installed on the steer-

ing wheel top surface.

• For some models, the steering wheel audio 

remote control switch and steering wheel voice 
control switch have been established for 
improved convenience.

• In addition to the round module pad which gives a 

sporty image, the integrated garnish has been 
employed for better appearance.

• The small-diameter steering wheel suitable for 

the sport drive has been adopted.

• The dual inflator has been adopted, which 

detects the impact exceeding a certain level upon 
collision, and controls the airbag deployment 
depending on the impact severity.

STEERING SHAFT AND COLUMN

M2370002000924

The steering column shaft is designed to improve 
operability and safety, and has the following features.

• The steering column layout has been optimized 

for better steering feeling (reduction of torque 
fluctuation) covering the whole tilting range.

• The collapsible steering column, with which the 

steering wheel moves forward on a collision, has 
been employed for improvement of passenger 
safety.

ENERGY ABSORBING MECHANISM

.

PRIMARY COLLISION

When a vehicle is crashed and the load is applied to the lower 
shaft from the gearbox side, the intermediate shaft (A) is forced 
into the intermediate shaft (B) to absorb the impact load.
