Power Steering System; Active Stability & Traction Control (Astc) - Mitsubishi L200 Owner's Manual

Power steering system

E00607400260
The power steering system operates while the en-
gine is running. It helps reduce the effort needed to
turn the steering wheel.
The power steering system has mechanical steering
capability in case the power assist is lost. If the pow-
er assist is lost for some reason, you will still be
able to steer your vehicle. If the power assist is
lost, you will notice it takes much more effort to
steer and that there is much more "free play" in the
steering wheel. If this happens, take your vehicle to
an authorized MITSUBISHI MOTORS dealer.
WARNING
l Do not stop the engine while the vehicle is
moving. Stopping the engine would make
the steering wheel extremely hard to
turn, possibly resulting in an accident.
CAUTION
l Do not leave the steering wheel turned all
the way in one direction. This can cause
damage to the power steering system.
Active Stability & Traction
Control (ASTC)*
E00616700344
The active stability & traction control (ASTC)
takes overall control of the anti-lock brake system,
traction control function and Active Stability Con-
trol function to help maintain the vehicle's control
and traction. Please read this section in conjunction
with the page on the anti-lock brake system, trac-
tion control function and Active Stability Control
function.

CAUTION
l Do not over-rely on the ASTC. This sys-
tem, like any other system, has limits and
cannot help you to maintain traction and
control of the vehicle in all circumstan-
ces. Reckless driving may lead to acci-
dents. Always drive carefully, taking into
account the traffic, road and environmen-
tal conditions.
l Be sure to use the same specified type and
size of tyre on all 4 wheels. Otherwise, the
ASTC may not work correctly.
NOTE
l After your vehicle is driven a short distance
after starting the engine, a click is heard from
the engine compartment; however, this is on-
ly the sound of ASTC being checked.
OCRE12E1
Starting and driving
l Some vibration will be felt in the vehicle
body and a whining sound of a motor will be
heard from the engine compartment when
the ASTC functions. This is a normal result
of the ASTC operation, and does not indicate
a malfunction.
l The ASTC does not operate while the ABS
warning lamp is illuminated.
l On vehicles with the rear differential lock,
the ASTC and ABS functions are suspended
while the rear differential lock is activated.
ASTC indication lamp, ASTC OFF indica-
tion lamp and ABS warning lamp are illumi-
nated while these functions are suspended. It
does not indicate a problem. When the rear
differential lock is disengaged, these lamps
go out and function again.
Refer to "ABS warning lamp" on page 4-45,
"ASTC indication lamp, ASTC OFF indica-
tion lamp" on page 4-48.
Driving hints
E00616800039
When extricating the vehicle from mud, sand or
fresh snow, you may find that operation of the
ASTC prevents the engine speed from increasing
in response to depression of the accelerator pedal.
If this happens and the vehicle remains stuck as a
result, deactivate the ASC function by pressing the
"ASC OFF" switch. The vehicle will then be easier
to extricate. (Brake control of the ATC function is
still working to prevent wheel spins when the ASC
function is deactivated by pressing the "ASC OFF"
switch.)
