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.
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 sys-
tem designed to help the driver main-
tain vehicle control under adverse
conditions. It is not a substitute for
safe driving practices. Factors includ-
ing speed, road conditions and driv-
er steering input can all affect
whether ESC will be effective in pre-
venting 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 cor-
responding sensation in the brake
pedal. This is normal and it means
your ESC is active.

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
overheat the engine.
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 7.
WARNING - Under/Over Inflated Tires
Always check the tires for prop-
er 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.

Maintenance
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
A wheel that is not the correct size
may adversely affect wheel and
bearing life, braking and stopping
abilities, handling characteristics,
ground clearance, body-to-tire clear-
ance, snow chain clearance,
speedometer and odometer calibra-
tion, headlight aim and bumper
height.
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'sspecifications may fit poorlyand result in damage to thevehicle or unusual handling andpoor vehicle control.

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
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate. Tires degrade over time, even when
they are not being used. Regardless
of the remaining tread, we recom-
mend that tires be replaced after
approximately six (6) years of nor-
mal service. Heat caused by hot cli-
mates or frequent high loading con-
ditions can accelerate the aging
process.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicles
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
The traction grade assigned to this
tire is based on straight-ahead brak-
ing traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction char-
acteristics.
