stop start MITSUBISHI ASX 2017 (in English) Service Manual

Brake system
The service brake is divided into two brake
circuits. And your vehicle is equipped with
power brakes. If one brake circuit fails, the
other is available to stop the vehicle. If you should lose the power assist for some reason, the brakes will still work. In these situations,
even if the brake pedal moves down to the
very end of its possible stroke or resists being
depressed, keep depressing the brake pedal down harder and further than usual; stop
driving as soon as possible and have the
brake system repaired.
WARNINGl Do not turn off the engine while your ve-
hicle is in motion. If you turn off the en-
gine while driving, the power assistance for the braking system will stop working
and your brakes will not work effectively.
l If the power assist is lost or if either brake
hydraulic system stops working properly, have your vehicle checked immediately.
Warning display
The brake warning lamp illuminates to indi-
cate a fault in the braking system. A warning
is also displayed on the multi-information display. Refer to “Brake warning lamp” on page 5-45 and “Brake warning display” on
page 5-46.
When brakes are wet
Check the brake system while driving at a
low speed immediately after starting, espe- cially when the brakes are wet, to confirmthey work normally.
A film of water can be formed on the brake
discs and prevent normal braking after driv-
ing in heavy rain or through large puddles, or after the vehicle is washed. If this occurs, dry
the brakes out by driving slowly while lightly depressing the brake pedal.
When driving downhill
It is important to take advantage of the en-
gine braking by shifting to a lower shift posi- tion while driving on steep downhill roads in order to prevent the brakes from overheating.
WARNINGl Do not leave any objects near the brake
pedal or let a floor mat slide under it; do- ing so could prevent the full pedal stroke
that would be necessary in an emergency. Make sure that the pedal can be operatedfreely at all times. Make sure the floor mat is securely held in place.Brake pad
l Avoid hard braking situations.
New brakes need to be broken-in by
moderate use for the first 200 km (124 miles).
l The disc brakes are provided with a
warning device which emits a shrieking
metallic sound while braking if the brake pads have reached their wear limit. Ifyou hear this sound, have the brake padsreplaced immediately.
WARNINGl Driving with worn brake pads will make
it harder to stop, and can cause an acci-
dent.Hill start assist*
E00628000155
The hill start assist makes it easy to start offon a steep uphill slope by preventing the ve-
hicle 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.
Hill start assist*
6-45OGAE17E2Starting and driving6

CAUTIONlDo not overly rely on the hill start assist to
prevent backwards movement of the vehicle. Under certain circumstances, even when hill
start assist is activated, the vehicle may
move backwards if the brake pedal is not sufficiently depressed, if the vehicle is heav-
ily loaded, or if the road is very steep or slip- pery.
l The hill start assist is not designed to keep
the vehicle stopped in place on uphill slopes for more than 2 seconds.
l When facing uphill, do not rely on using the
hill start assist to maintain a stopped position as an alternative to depressing the brake ped-
al.
Doing so could result in an accident.
l Do not perform the following operation
while the hill start assist is operating.
[Except for vehicles equipped with keyless operation system]
Turn the ignition switch to the “LOCK” or
“ACC” position.
[Vehicles equipped with keyless operation
system]
Put the operation mode in OFF or ACC.
The hill start assist could stop operating, which could result in an accident.To operate

place the selector lever into the “D” po- sition.NOTEl When reversing on an uphill slope, place the
gearshift lever or the selector lever into the
“R” position.
3. Release the brake pedal and the hill start
assist will maintain the braking force ap-
plied while stopping for approximately 2 seconds.
4. Depress the accelerator pedal and the
hill start assist gradually will decrease the braking force as the vehicle startsmoving.
NOTEl The hill start assist is activated when all of
the following conditions are met.
• The engine is running.
(The hill start assist will not be activated
while the engine is starting or immediate-
ly after the engine is started.)NOTE• On vehicles equipped with
M/T, the gear-
shift lever is in the following position.
[When starting an uphill slope forwards.]
The gearshift lever is in any position other
than “R”.
(The hill start assist will operate, even if the gearshift lever is in the “N” position.)
[When starting an uphill slope back-
wards.]
The gearshift lever is in the “R” position.
(The hill start assist will not operate when
the gearshift lever is in the “N” position.)
• On vehicles equipped with
A/T, CVT, the
selector lever is in any position other than “P” or “N”.
• The vehicle is completely stationary, with
the brake pedal depressed.
• The parking brake is released.
l The hill start assist will not operate if the ac-
celerator pedal is depressed before the brake pedal is released.

Restart the engine and check whether the warning display went out, in which case the
hill start assist is again working normally.
If the warning remains displayed or reap-
pears frequently, it is not necessary to stop the vehicle immediately, but the vehicle
should be inspected at a MITSUBISHI
MOTORS Authorized Service Point as soon
as possible.Brake assist system
E00627001588
The brake assist system is a device assistingdrivers who cannot depress the brake pedalfirmly when it is necessary to do so (such as
in emergency stop situations) and provides
greater braking force.

If the brake pedal is depressed suddenly, the brakes will be applied with more force than
usual.
CAUTIONl The brake assist system is not a device de-
signed to exercise braking force greater than its capacity. Make sure to always keep a suf-
ficient distance between vehicles in front of
you without relying too much on the brake
assist system.NOTEl Once the brake assist system is operational,
it maintains great braking force even if the
brake pedal is lightly released.
To stop its operation, completely remove
your foot from the brake pedal.
l The brake assist system may become opera-
tional when the brake pedal is fully de- pressed even if it has not been depressed suddenly. [Except for vehicles equipped
with Active Stability Control (ASC)]
l When the brake assist system is in use, you
may feel as if the depressed brake pedal issoft, the pedal moves in small motions inconjunction with the sound of the ABS oper- ation, or the vehicle body and the steering
wheel vibrate. This occurs when the brake
assist system is operating normally and does not indicate faulty operation. Continue to
firmly depress the brake pedal.
l You may hear an operation noise when the
brake pedal is suddenly or fully depressed
while stationary. This does not indicate a malfunction and the brake assist system is
operating normally.

system* E00626001190
This is a device that reduces the possibility ofrear end collisions by the rapid and automatic blinking of the hazard warning lamps to alert
vehicles approaching from behind during sudden braking. When the emergency stop
signal system operates, the hazard warning indication lamp in the instrument cluster
blinks rapidly at the same time.
CAUTIONl If the ABS warning or ASC warning is dis-
played, the emergency stop signal system may not operate.
Refer to “ABS warning lamp/display” on
page 6-49.
Refer to “ASC warning display” on page 6-53.NOTEl [Activating condition for the emergency stop
signal system]
It activates when all of the following condi-
tions are met.
• The vehicle speed is approximately
55 km/h (34 mph) or higher.
• The brake pedal has been depressed, and
the system judges that it was sudden brak- ing from the vehicle deceleration and theoperating condition of the anti-lock brake
system (ABS).
[Deactivating condition for the emergency
stop signal system]
It deactivates when one of the following conditions is met.
• The brake pedal is released.
• The hazard warning flasher switch is
pressed.
• The system judges that it was not sudden
braking from the vehicle deceleration and
the operating condition of the anti-lock
brake system (ABS).Anti-lock brake system
(ABS) E00607101046
The anti-lock brake system (ABS) helps pre-vent the wheels from locking up when brak-
ing. This helps maintain vehicle drivability and steering wheel handling.
Driving hints
l Always keep a safe distance from the ve-
hicle in front of you. Even if your vehi- cle is equipped with ABS, leave a great-
er braking distance when: • Driving on gravel or snow-covered
roads.
• Driving with tyre chains installed.
• Driving on uneven road surfaces.
l Operation of ABS is not restricted to sit-
uations where brakes are applied sud-
denly. This system may also prevent the
wheels from locking when you drive over manholes, steel roadwork plates, road markings, or any uneven road sur-
face.
l When the ABS is activated, you may
feel the brake pedal pulsation and the vi- brations of the vehicle body and steering
wheel. It may also feel as if the pedal re-
sists being pressed.
In this situation, simply hold the brake pedal down firmly. Do not
pump the brake, which will result in reduced braking performance.Emergency stop signal system*
6-48OGAE17E2Starting and driving6

lAn operation noise is emitted from the
engine compartment or you can feel a shock from the brake pedal when start
driving immediately after starting the en-
gine. These are normal sounds or opera- tions that the ABS makes when perform-ing a self-check. It does not indicate a
malfunction.
l The ABS can be used after the vehicle
has reached a speed over approximately 10 km/h (6 mph). It stops working when the vehicle slows below approximately5 km/h (3 mph).CAUTIONl The ABS cannot prevent accidents. It is your
responsibility to take safety precautions and to drive carefully.
l To prevent failure of the ABS, be sure all 4
wheels and tyres are the same size and the same type.
l Do not install any aftermarket limited-slip
differential (LSD) on your vehicle. The ABS may stop functioning properly.ABS warning lamp/display

Electric power steering
system (EPS) E00629200226
The power steering system operates while theengine 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 power assist is lost for some rea-
son, you will still be able to steer your vehi-
cle, but you will notice it takes much more effort to steer. If this happens, have your ve-hicle inspected at a MITSUBISHI MOTORS
Authorized Service Point.
Electric power steering system (EPS)
6-50OGAE17E2Starting and driving6

WARNINGlDo 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.NOTEl During repeated full-lock turning of the
steering wheel (for example, while you are manoeuvring the vehicle into a parking space), a protection function may be activa-
ted to prevent overheating of the power steering system. This function will make the
steering wheel gradually harder to turn. In
this event, limit your turning of the steering wheel for a while. When the system has
cooled down, the steering action will return to normal.
l If you turn the steering wheel while the vehi-
cle is stationary with the headlamps on, the
headlamps may become dim. This behaviour is not abnormal. The headlamps will returnto their original brightness after a shortwhile.Electric power steering system

ice Point as soon as possible. It may become
harder to turn the steering wheel.Active stability control
(ASC)* E00616700331
The Active Stability Control (ASC) takes
overall control of the anti-lock brake system, traction control function and stability control
function to help maintain the vehicle’s con-
trol and traction. Please read this section in conjunction with the page on the anti-lock
brake system, traction control function and stability control function.

Anti-lock brake system (ABS) ® p. 6-48
Traction control function ® p. 6-52
Stability control function ® p. 6-52CAUTIONl Do not over-rely on the ASC. Even the ASC
cannot prevent the natural laws of physics
from acting on the vehicle.
This system, like any other system, has lim-
its and cannot help you to maintain traction and control of the vehicle in all circumstan- ces. Reckless driving may lead to accidents. It is the driver’s responsibility to drive care-
fully. This means taking into account the traffic, road and environmental 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.

CAUTIONlDo not install any aftermarket limited-slip
differential (LSD) on your vehicle. The ASC
may stop functioning properly.NOTEl An operation noise may be emitted from the
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 turned to the
“ON” position or the operation mode is
put in ON.
• 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
normally. 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
E00619000087
On slippery surfaces, the traction control
function prevents the drive wheels from spin-
ning excessive, thus helping the vehicle to start moving from a stopped condition. It also
provides sufficient driving force and steering performance as the vehicle turns while press-
ing the acceleration pedal.
CAUTIONl 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
E00619100017
The stability control function is designed to
help the driver maintain control of the vehicle
on slippery roads or during rapid steering ma-
noeuvres. It works by controlling the engine output and brake on each wheel.
NOTEl The stability control function operates at
speeds of about 15 km/h (9 mph) or higher.“ASC OFF” switch

E00624400050CAUTIONl When towing the vehicle with only the front
wheels or only the rear wheels raised off the
ground, do not place the ignition switch in the “ON” position or do not put the opera- tion mode in ON. Placing the ignition switchin the “ON” position or putting the operation
mode in ON could cause the ASC to operate, resulting in an accident.
Note that the correct towing method depends
on the transmission type and the vehicle’s drive configuration.
For details, refer to “Towing” on page 8-20.Cruise control*
E00609101138
Cruise control is an automatic speed controlsystem that keeps a set speed. It can be acti-vated at about 40 km/h (25 mph) or more.
CAUTIONl When you do not wish to drive at a set
speed, turn off the cruise control for safety.CAUTIONl Do not use cruise control when driving con-
ditions 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, slippery, on a steep downhill slope.
l On vehicles with
M/T, do not move the
gearshift lever to the “N” (Neutral) position
while driving at a set speed without depress- ing the clutch pedal. The engine will run too
fast and might be damaged.NOTEl Cruise control may not be able to keep your
speed on uphills or downhills.
l Your speed may decrease on a steep uphill.
You may use the accelerator pedal if you
want to stay at your set speed.
l Your speed may increase to more than the
set speed on a steep downhill. You must use the brake to control your speed. As a result, the set speed driving is deactivated.

Accordingly, when the low tyre pressure tell-tale illuminates, you should stop and check
your tyres as soon as possible, and inflate them to the proper pressure. Driving on a sig-nificantly under-inflated tyre causes the tyre
to overheat and can lead to tyre failure.
Under-inflation also reduces fuel efficiency and tyre tread life, and may affect the vehi-
cle’s handling and stopping ability.
Please note that the tyre pressure monitoring system (TPMS) is not a substitute for proper
tyre maintenance, and it is the driver’s re- sponsibility to maintain correct tyre pressure,
even if under-inflation has not reached the
level to trigger illumination of the tyre pres- sure monitoring system (TPMS) low tyre
pressure telltale.
Your vehicle has also been equipped with a
warning lamp to indicate when the system is
not operating properly.
The warning lamp is combined with the low tyre pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one mi- nute and then remain continuously illumina-
ted. This sequence will continue upon subse- quent vehicle start-ups as long as the mal-
function exists.
When the warning lamp is illuminated, the
system may not be able to detect or signal low tyre pressure as intended.The tyre pressure monitoring system (TPMS)
malfunctions may occur for a variety of rea- sons, including the installation of replace- ment or alternate tyres or wheels on the vehi-cle that prevent the tyre pressure monitoring
system (TPMS) from functioning properly. Always check the tyre pressure monitoring
system (TPMS) malfunction telltale after re- placing one or more tyres or wheels on yourvehicle to ensure that the replacement or al- ternate tyres and wheels allow the tyre pres-
sure monitoring system (TPMS) to continue to function properly.If the warning lamp/display il-
luminates while driving
E00637300037
1. If the warning lamp illuminates, avoid
hard braking, sharp steering manoeuvres and high speeds. You should stop andadjust the tyres to the proper inflationpressure as soon as possible. Adjust the
spare tyre at the same time. Refer to “Tyres” on page 10-13
NOTEl In addition, the warning display will be dis-
played on the information screen in the mul-
ti-information display.
l When inspecting or adjusting the tyre pres-
sure, do not apply excessive force to the
valve stem to avoid breakage.NOTEl After inspecting or adjusting the tyre pres-
sure, always reinstall the valve cap on the
valve stem.
Without the valve cap, dirt or moisture could
get into the valve, resulting in damage to the tyre inflation pressure sensor.
l Do not use metal valve caps, which may
cause a metal reaction, resulting in corrosion and damage of the tyre inflation pressure
sensors.
l Once adjustments have been made, the
warning lamp will go off after a few minutesof driving.
2. If the warning lamp remains illuminated
after you have been driving for about 10
minutes after you adjust the tyre infla- tion pressure, one or more of the tyresmay have a puncture. Inspect the tyreand if it has a puncture, have it repaired
by a MITSUBISHI MOTORS Author-
ized Service Point as soon as possible.
WARNINGl If the warning lamp/display illuminates
while you are driving, avoid hard brak- ing, sharp steering manoeuvres and high speeds.
Driving with an under-inflated tyre ad-
versely affects vehicle performance and
can result in an accident.
