2015 KIA Optima stop start

513
Driving your vehicle
If the battery is weak or the smartkey does not work correctly, you
can start the engine by pressing
the engine start/stop button with
the smart key.
The side with the lock button
should contact the engine
start/stop button directly.
When you press the engine
start/stop button directly with the
smart key, the smart key should
contact the button at a right angle. When the stop lamp fuse is blown,
you can't start the engine normally.
Replace the fuse with a new one. If
it is not possible, you can start the
engine by pressing the ENGINE
START/STOP button for 10 sec-
onds while it is in the ACC posi-
tion. The engine can start without
depressing the brake pedal. But for
your safety always depress the
brake pedal before starting the
engine.
Do not press the ENGINE START/
STOP button for more than 10 sec-
onds except when the stop lamp fuse
is blown.

Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light will illumi-
nate when the parking brake is
applied with the ignition switch in the
START or ON position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while the engine is running, there
may be a malfunction in the brake
system. Immediate attention is nec-
essary. If at all possible, stop driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location or repair
shop.
Anti-lock brake system (ABS)
ABS (or ESC) will not prevent acci-
dents due to improper or dangerous
driving maneuvers. Even though
vehicle control is improved during
emergency braking, always maintain
a safe distance between you and
objects ahead. Vehicle speeds
should always be reduced during
extreme road conditions.
The vehicle should be driven at
reduced speeds in the following cir-
cumstances:
When driving on rough, gravel or
snow-covered roads
When driving on roads where the road surface is pitted or has differ-
ent surface heights.
Driving in these conditions increases
the stopping distance for your vehi-
cle.

Driving your vehicle
The ABS continuously senses the
speed of the wheels. If the wheels
are going to lock, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ABS is active.
In order to obtain the maximum ben-
efit from your ABS in an emergency
situation, do not attempt to modulate
your brake pressure and do not try to
pump your brakes. Press your brake
pedal as hard as possible or as hard
as the situation allows the ABS to
control the force being delivered to
the brakes.✽ ✽NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the anti-lock brake
system is functioning properly.
Even with the anti-lock brake sys-
tem, your vehicle still requires suf-
ficient stopping distance. Always
maintain a safe distance from the
vehicle in front of you.
Always slow down when cornering. The anti-lock brake system cannot
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system. The ABS warning light will stay on for
approximately 3 seconds after the
ignition switch is ON. During that
time, the ABS will go through self-
diagnosis and the light will go off if
everything is normal. If the light stays
on, you may have a problem with
your ABS but your regular brakes will
work normally. Contact an authorized
Kia dealer as soon as possible.

When you drive on a road with
poor traction, such as an icy road,
and operated your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light may illuminate. Pull your vehi-
cle over to a safe place and stop
the engine.
Restart the engine. If the ABS warning light is off, then your ABS
is normal. Otherwise, you may
have a problem with the ABS.
Contact an authorized Kia dealer
as soon as possible.✽ ✽ NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on
at the same time. This happens
because of the low battery voltage. It
does not mean your ABS has mal-
functioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic stability control
(ESC)
The Electronic Stability control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle.
Electronic stability control (ESC) will
not prevent accidents. Excessive
speed in turns, abrupt maneuvers
and hydroplaning on wet surfaces
can still result in serious accidents.

WARNING
For maximum protection,
always wear your seat belt. No
system, no matter how
advanced, can compensate for
all driver error and/or driving
conditions. Always drive
responsibly.

When operating
When the ESC is in opera-
tion, ESC indicator light
blinks.
Stability Control is operat-
ing properly, you can feel a
slight pulsation in the vehi-
cle. This is only the effect
of brake control and indi-
cates nothing unusual.

pressing the accelerator
pedal may not cause the

per minute) to increase.ESC operation off
ESC OFF state
This car has 2 kinds of ESC
off states.
If the engine stops when
ESC is off, ESC remains off.
Upon restarting the engine,
the ESC will automatically
turn on again.
ESC off state 1
To cancel ESC operation, press the
ESC OFF button (ESC OFF )
shortly (ESC OFF indicator light
(ESC OFF ) illuminates). At this
state, the engine control function
does not operate. It means the trac-
tion control function does not oper-
ate. Brake control function only oper-
ates.

ESC OFF usage
When driving
It’s a good idea to keep the ESC
turned on for daily driving whenev-
er possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
Never press the ESC OFF button
while ESC is operating (ESC indica-
tor light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip out of
control.
Hill-start assist control (HAC)
Hill start Assist Control is a comfort
function. The main intent is to pre-
vent the vehicle from rolling back-
wards while driving uphill on an
inclined surface. HAC holds the brak-
ing pressure builtup by driver during
stopping procedure for 2 seconds
after releasing brake pedal.
During the pressure-hold period, the
driver has enough time to press the
accelerator pedal to drive off.
The braking pressure is reduced as
soon as the system detects the dri-
ver’s intention to drive off. The HAC does not operate when
the transaxle shift lever is in the P
(Park) or N (Neutral) position.
The HAC activates even though the ESC is off but it does not acti-
vate when the ESC has malfunc-
tioned.
WARNING - Operating
ESC
Never press the ESC OFF but-
ton while ESC is operating.
If the ESC is turned off while
ESC is operating, the vehicle
may go out of control.WARNING- Maintaining
Brake Pressure on Incline
HAC does not replace the need
to apply brakes while stopped on
an incline. While stopped, make
sure you maintain brake pres-
sure sufficient to prevent your
vehicle from rolling backward
and causing an accident. Don’t
release the brake pedal until you
are ready to accelerate forward.
WARNING
For maximum protection,
always wear your seat belt. No
system, no matter how
advanced, can compensate for
all driver error and/or driving
conditions. Always drive
responsibly.

Limitation of Active ECO opera-
tion:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though
there is no change in the ECO indi-

When the coolant temperature is
low:
The system will be limited until
