Traction control function
E00611800050
On slippery surfaces, the traction control function prevents the
drive wheels from excessive spinning, thus helping the vehicle
to start moving from a stop. It also provides sufficient driving
force and steering performance as the vehicle turns at acceler-
ated speeds.NOTE●When moving out of mud, sand or fresh snow, pressing
the accelerator pedal may not allow the engine speed to
increase.
If this happens and the vehicle remains stuck as a result,
turn the TCL switch OFF. The vehicle will then be easier
to extricate.
●When climbing or beginning to climb a steep slope, turn
the TCL switch OFF if the traction control function
reduces the engine speed excessively.
TCL switch
E00611900048
The traction control function automatically goes on, when the
ignition switch is turned to the “ON” position. To deactivate
the traction control function, press the TCL switch. To reacti-
vate the traction control function, press the TCL switch again.
MITSUBISHI MOTORS recommends to normally keep the
traction control function on.
CAUTION
!●When driving a vehicle on a snowy or icy road, be
sure to install snow tyres and drive the vehicle at
moderate speeds.●When a tyre such as a compact spare tyre, which is
different in size from the standard tyre, has been
installed, make sure that the traction control func-
tion is turned off.

Stability control function
E00612000088
The stability control function is designed to help maintain the
vehicle’s control in slippery conditions, or during rapid steer-
ing manoeuvres. It works by controlling the engine output and
the brake on each wheel.NOTE●The stability control function operates at speeds of about
30 km/h (19 mph) or higher.
ASC indication lamp, TCL OFF indication lamp
E00612100089
The traction control function and stability control function
share the same indication lamp.
The indication lamps should illuminate when the ignition
switch is turned to the “ON” position, and should go off after a
few seconds. Always make sure that the lamp goes out before
beginning to drive.
If one or both indication lamps stay on or do not illuminate
when the ignition switch is turned to the “ON” position, we
recommend you to consult a MITSUBISHI MOTORS Author-
ized Service Point.

CAUTION
!●When the indication lamp blinks, ASC is operat-
ing, which means that the road is slippery or that
your vehicle’s wheels are slipping excessively. If this
happens, drive slower with less accelerator input.●If a malfunction occurs in the device, the and
indication lamps will continuously illuminate. Park
your vehicle in a safe place and stop the engine.
Then, start the engine again and check whether the
and indication lamps go out.
If the and indication lamps remain on even
after your vehicle is driven a short distance after
starting the engine, we recommend you to consult a
MITSUBISHI MOTORS Authorized Service Point.●If continuous brake control (on a slippery surface,
for example) causes the temperature of the braking
system to increase excessively, the traction control
function (working by controlling the brake on each
wheel) will be suspended to protect the braking sys-
tem. [The traction control function (working by con-
trolling the engine output) will operate. Normal
operation of the vehicle will not be affected.] At this
time, the indication lamp will blink to inform the
driver that the traction control function (working by
controlling the brake on each wheel) is suspended. If
the vehicle is stopped and the indication lamp
goes off, the traction control function (working by
controlling the brake on each wheel) will start oper-
ating again.
CAUTION
!●If the vehicle is towed with the ignition switch in the
“ON” position and only the front wheels or only the
rear wheels raised off the ground, the traction con-
trol function may operate, resulting in an accident.
When towing the vehicle with the front wheels
raised, keep the ignition switch in the “LOCK” or
“ACC” position. When towing the vehicle with the
rear wheels raised, keep the ignition switch in the
“ACC” position.
Refer to “Towing” on page 6-28.

4 Auto-speed (cruise) control
*
E00609100391
Auto-speed control is an automatic speed control system. It lets
you keep the same driving speed, auto-speed control can be
used at about 40 km/h (25 mph) or more. It is especially useful
for highway driving. Auto-speed control does not work at
speeds below about 40 km/h (25 mph).
NOTE●Auto-speed control may not be able to keep your speed on
uphills or downhills.
●Your speed may drop on a steep uphill. You must use the
accelerator pedal if you want to stay at your set speed.
●Your speed may increase to more than the set speed on a
steep downhill. You must use the brake to control your
speed. If your speed increases too much, turn off the auto-
speed control. (Refer to “To deactivate” on page 4-50.)
A- Main switch
B- Auto-speed control lever
CAUTION
!●For safety reasons, deactivate the cruise control sys-
tem using the main switch (A) when you are not
using the auto-speed control system.
(Refer to “To deactivate” on page 4-50.)
●Auto-speed control is not recommended when driv-
ing conditions will not allow you to stay at the same
speed, such as in heavy traffic or on roads that are
winding, icy, snow-covered, wet, or slippery, or on a
steep downhill.●For vehicles with M/T, if you shift to “N” (Neutral)
position in auto-speed control mode without press-
ing the clutch first, the engine will run too fast and
might be damaged.

2. Pull the lever (B) down while driving at the desired speed.NOTE●If the main switch is on when the ignition switch is turned
to “LOCK” or “ACC” position, auto-speed control will be
on automatically the next time you start the engine. The
CRUISE indication lamp will also come on. You will need
to reset the speed however, if you want to use auto-speed
control.
●If the battery voltage is insufficient, the memory data for
the main switch will be erased.
As a result, the CRUISE indication lamp may not come on
when you restart the engine.
If this happens, push in the main switch once again to acti-
vate the system.
●On diesel-powered vehicles, it is not possible to set the
vehicle speed while driving in 1st gear.
To increase the set speed
E00609400323
There are 2 ways to increase the set speed.Auto-speed control leverPull the auto-speed control lever up and hold it while driving at
the set speed, and you will increase gradually.
When you reach your desired speed, release the switch. Your
cruising speed is now set.
To increase your speed in small amounts, press the auto-speed
control lever up for less than 1 second and release it. Each time
you press the lever up, your vehicle will go about 1.6 km/h
(1 mph) faster.

Vehicles with a towbar
The detection areas are within approximately 50 cm (A) from
the corner sensors, 100 cm (B) from the back sensors, and
60 cm (C) or less from the ground surface, excluding the area
approximately 10 cm (D) from the ground surface. The non-
detection areas (E) are within approximately 20 cm (F) from
the bumper.NOTE●If the rear bumper has been exposed to an impact, the cor-
ner or back sensors may fail and prevent the system from
functioning properly. We recommend you to have your
vehicle inspected.
●The sensors do not detect objects located in the area
directly below or near the bumper. If the height of an
object is lower than the mounted position of the corner or
back sensors, the sensors may not continue detecting it
even if they detected it initially.For information on how to change the detection areas, please
refer to “Changing the detection areas” on page 4-56.
CAUTION
!●The corner sensor system may not operate properly
under the following conditions:
• The sensors or surroundings are covered with ice,
snow, or mud.• The sensors are frozen.• The system receives ultrasonic noise from other
sources (the horns of other vehicles, motorcycle
engines, brakes, radios, pouring rain, splashing
water, tyre chains, etc.).• The sensors are extremely hot or cold (while the
vehicle is parked for a long period of time under a
blazing sun or in cold weather).• The vehicle tilts significantly.• The vehicle is driven on a rough road (with a
bumpy, gravel, hilly, or grassy surface).• The vehicle is too close to an obstacle.• The sensors or surroundings have been wiped by
hand, or stickers or accessories have been
attached.
●The corner sensor system may not properly detect
the following:
• Objects that are thin, such as wire nets or ropes.• Objects that absorb sound waves, such as snow.• Objects that are shaped with a sharp angle.• Objects with a smooth surface, such as glass.• Objects that are low, such as kerbstones.
