Mitsubishi Outlander XL. Manual — part 1294

GENERAL INFORMATION

M23700000001USA0000010000

FEATURES

A hydraulic power steering system has been adopted
to all models.
This steering system offers the following features:

｠

The support method of the steering gear to the
crossmember is realized by the left and right
internal bushings with inner cylinders. This support
method achieves higher rigidity of the steering gear
and improves the steering feeling.

｠

Configuring the optimum flow characteristics and
gear valve feature improves the handling stability.

｠

Appropriate application of friction to the steering
gear cuts off the disturbance from the road surface

and improves the stability during the straight-ahead
driving.

｠

One-way check valve for the power steering fluid
has been added in the steering gear. By reducing
the kickback due to the disturbance from the
uneven road surface, the handling stability has
been improved.

｠

As the pressure sensor for increasing the engine
idling speed during power steering operation, the
sensor which can precisely detect the pressure in
the power steering system.

｠

Optimization of the flexible tube in the high pressure
hose reduces the pump noise.

The steering wheel is designed to improve operability,
safety and maintainability and has the following
features:

｠

Newly designed three-spoke type has been
adopted. For LS models, the steering wheel is made
of urethane. For XLS models, the steering wheel is
made of genuine leather.

｠

Remote steering wheel audio control switches are
available on same models.

｠

Sporty and thick type grip shape has been adopted.

｠

Rigid core metal reduces the steering wheel
vibration.

｠

It incorporates an SRS airbag to protect the driver
in the event of a frontal collision.

｠

The airbag module is equipped with an inflator that
does not contain sodium azide.

｠

Optimization of the airbag specifications reduces
the risk of injury to the passengers in a collision.

The steering column is designed to improve
operability, safety and maintainability and has the
following features:

｠

To improve the feeling of steering (reduction of
torque fluctuation) covering the whole tilting range,
the steering column layout has been optimized by
focusing the tilting function.

｠

Tilt steering mechanism has been employed on all
models (Tilt-up amount: 20mm/Tilt-down amount:
25mm).

｠

Collapsible steering column has been employed.
During a collision, the steering wheel moves
forward.

｠

To reduce the separation load during a collision, the
sliding resistance reduction member has been
installed to the column bracket.

Intermediate shaft (A)

Intermediate shaft (B)

If the vehicle is involved in a crash and impact energy is
transmitted to the lower shaft from the gearbox side, the
intermediate shaft (A) will be pushed into intermediate shaft (B)
to absorb impact energy. Thus, the steering column will not be
projected into the passenger compartment.

Column

Rivet pin

Column pipe

When the driver's body falls against the steering wheel via the
deployed air bag, the column bracket moves forward by
deforming the rivet pin of the one-way capsule, and
simultaneously the steering column assembly frees from the pin
of column bracket to move forward and downward.
