The ABS warning light will stay on for
approximately 3 seconds after the
engine start/stop button 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. Contact an
authorized Kia dealer as soon as
possible. When you drive on a road having
poor traction, such as an icy road,
and have operated your brakes
continuously, the ABS will be active
continuously 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 goes off, then your
ABS system 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 low battery voltage. It does not
mean your ABS has malfunctioned.
• 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.

Driving your 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.
Only a safe and attentive driver can
prevent accidents by avoiding
maneuvers that cause the vehicle to
lose traction. Even with ESC
installed, always follow all the normal
precautions for driving - including
driving at safe speeds for the condi-
tions.The Electronic Stability Control (ESC)
system is an electronic system
designed to help the driver maintain
vehicle control under adverse condi-
tions. It is not a substitute for safe driv-
ing practices. Factors including speed,
road conditions and driver steering
input can all affect whether ESC will be
effective in preventing a loss of control.
It is still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.
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 corresponding sensa-
tion in the brake pedal. This is normal
and it means your ESC is active.✽ ✽
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 Electronic
Stability Control System is function-
ing properly.
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.

state, only the brake control function
will operate.
To turn off the traction control func-
tion and the brake control function to
ESC operation, press the ESC OFF
button (ESC OFF ) for more than 3
seconds. ESC OFF indicator light
(ESC OFF ) will illuminate and the

When engine start/stop button is
turned to ON, the indicator light illu-
minates, then goes off if the ESC
system is operating normally.
The ESC indicator light blinks when-
ever ESC is operating or illuminates
when ESC fails to operate.
The ESC OFF indicator light comes
on when the ESC is turned off with
the button.

The warning light illumi-
nates on the LCD display
when you cancel the FCA
system. The driver can
monitor the FCA ON/OFF status on
the LCD display. Also, the warning
light illuminates when the ESC
(Electronic Stability Control) is
turned off (Traction & Stability control
disabled.).
When the warning light remains ON
with the FCA activated, take your
vehicle to an authorized Kia dealer
and have the system checked.
The driver can select the initial warn-
ing activation time in the User
Settings in the instrument cluster
LCD display. The options for the ini-
tial Forward Collision Warning
include the following:
selected, the initial
Forward Collision Warning
is activated earlier than
normal. This setting maxi-
mizes the amount of dis-
tance between the vehicle
or pedestrian ahead before
the initial warning occurs. If
the ‘EARLY’ condition feels
too sensitive, change it into
‘NORMAL’. When the vehi-
cle ahead suddenly stops,
the warning may seem to
activate later even if the
‘EARLY’ condition was
selected.
selected, the initial
Forward Collision
Warning is activated nor-
mally. This setting allows
for a nominal amount of
distance between the
vehicle or pedestrian
ahead before the initial
warning occurs.
selected, the initial Forward
Collision Warning is activat-
ed later than normal. This
setting reduces the amount
of distance between the
vehicle or pedestrian ahead
before the initial warning
occurs. Select this condition
only when traffic is light,
and you are driving slowly.

Driving your vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING- Under/overinflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
WARNING- Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out tires
should be replaced as soon as
possible. For further information
and tread limits, refer to "Tires
and wheels" in chapter 8.

Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. Slow down whenever there
is rain, snow or ice on the road, to
reduce the possibility of losing con-
trol of the vehicle.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tire in
case of a recall.
1. Manufacturer or brand name
Manufacturer or Brand name is
shown.
CAUTION - Wheel
Wheels that do not meet Kia's
specifications may fit poorlyand result in damage to thevehicle or unusual handling andpoor vehicle control.

3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date,
(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of the
wheel), displaying the DOT Code.
The DOT Code is a series of num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1618 represents
that the tire was produced in the 16th
week of 2018.
4. Tire ply composition and mate-rial
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflationpressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum per-
missible inflation pressure. Refer to
the Tire and Loading Information label
for recommended inflation pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as
the factory installed tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example:
TREADWEAR 440
TRACTION A
TEMPERATURE A
WARNING - Tire age
Replace tires within the recom-
mended time frame. Failure to
replace tires as recommended
can result in sudden tire failure,
which could lead to a loss of
control and an accident.
