3Cautions on handling of all-wheel drive
vehicles
N00530800145
Tires and wheelsSince driving torque can be applied to all four wheels, the per-
formance of the vehicle when operating in all-wheel drive is
greatly affected by the condition of the tires.
Pay close attention to the tires.

Install specified tires on all wheels. Refer to “Tires and
wheels” on page 9-10.

Be sure to fit all four tires and wheels of the same size and
type.
When replacement of any of the tires or wheels is neces-
sary, replace all of them.

All tires should be rotated whenever the wear difference
between the front and rear tires is recognizable.
Good vehicle performance cannot be expected if there is a dif-
ference in wear between tires. Refer to “Tire rotation” on page
7-36.

Check the tire inflation pressure regularly.
CAUTION
!
Always use tires of the same size, same type, and
same brand, and which have no wear differences.
Using tires that differ in size, type, brands or the
degree of wear, will increase the differential oil tem-
perature, resulting in possible damage to the driving
system. Further, the drive train will be subjected to
excessive loading, possibly leading to oil leakage,
component seizure, or other serious problems.

Towing Jacking up a all-wheel drive vehicles
CAUTION
!
Do not tow all-wheel drive vehicles with the front or
rear wheels on the ground (Type A or Type B) as
illustrated. This could result in damage to the driv-
etrain, or unstable towing.
If you tow all-wheel drive vehicles, use Type C or
Type D equipment.
WARNING
!
Do not start or run the engine while the vehicle is on
the jack.
The jack could slip out of position and result in an
accident.

3ACD (Active center differential system)
(if so equipped)
N00538500034
The ACD is a system that improves acceleration performance
and straight-ahead stability by regulating the differential limit-
ing action and power drive distribution of the center differen-
tial.NOTE
If the parking brake lever is pulled up while the vehicle is
moving, the center differential is designed to switch to a
free state condition which will allow the rear wheel to
lock easier.
ACD control mode
N00545400048
Select the control mode from the following three types to suit
the driving conditions.
CAUTION
!
Do not over-rely on the ACD. Even the ACD cannot
prevent the natural laws of 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 can lead to accidents. It is the driver’s
responsibility to drive carefully. This means taking
into account the traffic, road and environmental
conditions.
Be sure to use tires that are the same specified size,
type, and brand, and have no difference in the
amount of wear for all four wheels. Otherwise, the
ACD may not work properly.
ACD control
mode
Operation
TA R M A CNormally, use this control mode. Use this
mode for paved roads.
GRAVELUse this control mode when driving on some-
what slippery road surfaces, such as wet road
surfaces and gravel roads.
SNOWUse this control mode when driving on slip-
pery road surfaces, such as snow-covered
roads.

ACD control mode switchWhen the ignition switch is set to the “ON” position, operate
the AWC switch to change the control mode.
Each time the switch is pushed, the control mode changes in
the order “TARMAC” → “GRAVEL” → “SNOW” → “TAR-
MAC”.NOTE
The control mode can be changed while the vehicle is
moving.

The selected control mode is stored in memory even if the
engine is stopped.
However, if a battery terminal is disconnected, the control
mode stored in memory will be erased and the control
mode will be set to the “TARMAC” mode.
ACD control mode displayExample: “TARMAC” mode is selected.
The currently selected control mode is displayed on the multi-
information display.
In addition, when the control mode is changed, the selected
mode appears on the interrupt display screen of the information
screen in the multi-information display.
The control mode display will appear on the information
screen for a few seconds, and then the original screen will
return.
CAUTION
!
The ACD control mode display may flash under
aggressive driving conditions.
At this time, ACD control is temporarily suspended
in order to protect the ACD device, but this will not
affect normal driving.
After the vehicle is driven for a while, if the ACD
control mode display remains on, the ACD control
will start operating again.

ACD warning display
N00545700041
When there is a malfunction in the system, the warning dis-
play will appear on the information screen in the multi-infor-
mation display.
In addition, the ACD control mode display in section (A) will
go out at the same time.
NOTE
If the ambient temperature drops and the viscosity of the
AWC control fluid increases, the warning may be dis-
played.
At this time, ACD control is temporarily suspended, but
this will not affect normal driving.
After the vehicle is driven for a while, if the engine is
restarted after the AWC control fluid warms up or the
ambient temperature increases, the ACD control will start
operating again if the warning display goes out.
CAUTION
!
The system may be malfunctioning.
Park your vehicle in a safe place and stop the engine.
Restart the engine and check whether the warn-
ing display goes out.
If the warning display goes out, there is no
abnormal condition. If the warning display does
not go out or appears frequently, it is not necessary
to stop the vehicle immediately, but we recommend
you to have your vehicle inspected.

3 Limited-slip differential
(if so equipped)
N00517400069
A limited-slip differential is applied for rear wheel differential.
The features of this limited-slip differential are described
below:
Just as with a conventional differential, the wheel on one side
is allowed to turn at a different speed from the wheel on the
other side when the vehicle is cornering. The difference
between the limited-slip differential and a conventional differ-
ential is that if the wheel on one side of the vehicle loses trac-
tion, a greater amount of torque is applied to the wheel on the
other side to improve traction.NOTE
Even if there is a difference in the amount of traction the
wheels can get, if both of them are spinning, the limited-
slip differential will not be effective.
Service brake
N00517500262
Brake pedalOveruse of the brake can cause poor brake response and pre-
mature wear of the brake pads and linings.
When driving down a long or steep hill, use engine braking by
downshifting.
CAUTION
!
Never start the engine while one of the front or rear
wheels is jacked up and the other in contact with the
ground; doing so may cause the vehicle to jump for-
ward.
Continuously attempting to extract the vehicle from
snow, mud, etc. while using high engine rpm may
damage the limited-slip differential.
Using a compact spare wheel will adversely affect
the limited-slip differential; replace the compact
spare wheel with a standard size wheel as soon as
possible.
WARNING
!
Do not leave any objects near the brake pedal or let
a floor mat slide under it; doing so could prevent the
full pedal stroke that would be necessary in an emer-
gency. Make sure that the pedal can be operated
freely at all times. Make sure the floor mat is
securely held in place.
CAUTION
!
It is important not to drive the vehicle with your foot
resting on the brake pedal when braking is not
required. This practice can result in very high brake
temperatures, premature pad and lining wear, and
possible damage to the brakes.

Power brakes
N00517600377
Your vehicle is equipped with power brakes for more braking
force with minimal brake pedal effort.
Your brakes are designed to operate at full capacity, even if the
power assist is lost.
If the power assist is lost, the effort needed to press the brake
pedal is greater.
If you should loose the power assist for some reason, the
brakes will still work.
If the power brake unit or either of the two brake hydraulic sys-
tems stops working properly, the rest of the brake system will
still work, but the vehicle will not slow down as quickly.
You will know this has happened if you find you need to
depress the brake pedal down further, or harder when slowing
down or stopping, or if the brake warning light and the warning
display in the multi-information display come on.
Brake pad wear alarm
N00532500087
The disc brakes have an alarm that makes a metallic squeal
when the brake pads have worn down enough to need service.
If you hear this sound, have the brake pads replaced at an
authorized Mitsubishi Motors dealer or a repair facility of your
choice.
WARNING
!
Never coast downhill with the engine OFF. Keep the
engine running whenever your vehicle is in motion.
If you turn off the engine while driving, the power
brake booster will stop working and your brakes
will not work as well.
If the power assist is lost or if either brake hydraulic
system stops working properly, take your vehicle to
an authorized Mitsubishi Motors dealer or a repair
facility of your choice immediately.
WARNING
!
Driving with worn brake pads will make it harder to
stop, and can cause an accident.

3 Hill start assist
(vehicles with Twin Clutch SST)
N00562600032
The hill start assist makes it easy to start off on a steep uphill
slope by preventing the vehicle from moving backwards. It
keeps the braking force for about 2 seconds when you move
your foot from the brake pedal to the accelerator pedal.
To operate
N00562700033
1. Stop the vehicle completely using the brake pedal.
2. Release the brake pedal and the hill start assist will main-
tain the braking force applied while stopping for approxi-
mately 2 seconds.
3. Depress the accelerator pedal and the hill start assist grad-
ually will decrease the braking force as the vehicle starts
moving.NOTE
The hill start assist is activated when all of the following
conditions are met.
• The engine is running.
• The gearshift lever is in any position other than “P”
(PARK) or “N” (NEUTRAL).
• The vehicle is completely stationary, with the brake
pedal depressed.
• The parking brake is released.

The hill start assist will not operate if the accelerator pedal
is depressed before the brake pedal is released.

The hill start assist also operates when reversing on an
uphill slope.
CAUTION
!
Do not overly rely on the hill start assist to prevent
backwards movement of the vehicle. Under certain
circumstances, even when hill start assist is acti-
vated, the vehicle may move backwards if the brake
pedal is not sufficiently depressed, if the vehicle is
heavily loaded, or if the road is very steep or slip-
pery.
The hill start assist is not designed to keep the vehi-
cle stopped in place on uphill slopes for more than 2
seconds.
When facing uphill, do not rely on using the hill
start assist to maintain a stopped position as an
alternative to depressing the brake pedal.
Doing so could cause an accident.
Do not turn the ignition switch to the “LOCK” or
“ACC” position while the hill start assist is operat-
ing. The hill start assist could stop operating, which
could result in an accident.
