Active Stability Control (Asc) - Mitsubishi OUTLANDER Owner's Manual

Starting and driving

Active stability control (ASC)*

The Active Stability Control (ASC) takes overall
control of the anti-lock brake system, traction con-
trol function and stability control 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, traction control func-
tion and stability control function.

CAUTION
l Do not over-rely on the ASC. Even the
ASC cannot prevent the natural laws of
4
physics from acting on the vehicle.
This system, like any other system, has
limits and cannot help you to maintain
traction and control of the vehicle in all
circumstances. Reckless driving may lead
to accidents. It is the driver's responsibil-
ity to drive carefully. This means taking
into account the traffic, road and environ-
mental conditions.
l
Be sure to use the same specified type and
size of tyre on all 4 wheels. Otherwise, the
ASC may not work properly.
l Do not install any aftermarket limited-
slip differential (LSD) on your vehicle.
The ASC may stop functioning properly.

NOTE
l An operation noise may be emitted from the
E00616700155
engine compartment in the following situa-
tions. The sound is associated with checking
the operations of the ASC. At this time, you
may feel a shock from the brake pedal if you
depress it. These do not indicate a malfunc-
tion.
• When the ignition switch is set to the
"ON" position.
• When the vehicle is driven for a while af-
ter the engine is turned on.
l When the ASC is activated, you may feel a
vibration in the vehicle body or hear a whin-
ing sound from the engine compartment.
This indicates that the system is operating nor-
mally. It does not indicate a malfunction.
l When the anti-lock brake system warning
lamp is illuminated, the ASC is not active.
Traction control function
On slippery surfaces, the traction control function
prevents the drive wheels from excessive spinning,
thus helping the vehicle to start moving from a stop-
ped condition. It also provides sufficient driving
force and steering performance as the vehicle turns
while pressing the acceleration pedal.
CAUTION
l When driving a vehicle on a snowy or icy
road, be sure to install snow tyres and
drive the vehicle at moderate speeds.
Stability control function
The stability control function is designed to help
the driver maintain control of the vehicle on slip-
pery roads or during rapid steering manoeuvres. It
works by controlling the engine output and brake
on each wheel.
NOTE
l The stability control function operates at
speeds of about 15 km/h (9 mph) or higher.
"ASC OFF" switch
The ASC is automatically activated when the igni-
tion switch is turned to the "ON" position. You can
deactivate the system by pressing down the "ASC
OFF" switch for 3 seconds or longer.
