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.

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.
