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 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 stabilize 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 management
system to stabilize the vehicle.
CAUTION
When you drive on a road with
poor traction, such as an icy road,and operated your brakes contin-uously, the ABS will be activecontinuously and the ABS warn- ing light may illuminate. Pull yourvehicle over to a safe place andstop the engine.
Restart the engine. If the ABS warning light is off, then yourABS system is normal.Otherwise, you may have a prob-lem with the ABS. Contact anauthorized Kia dealer as soon aspossible.

Indicator light
When the ignition switch is turned ON,
the indicator light illuminates, then goes
off if ESC system is operating normally.
The ESC indicator light blinks whenever
ESC is operating.
ESC OFF indicator light comes on when
either the ESC is turned off with the but-
ton, or ESC fails to operate when turned
on.
ESC OFF usage
When driving
It’s a good idea to keep the ESC turnedon for daily driving whenever 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 indicator light
blinks).
If ESC is turned off while ESC is operat-
ing, the vehicle may slip out of control.
✽ ✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light illuminat-
ed). If the ESC is left on, it may pre-
vent the vehicle speed from increas-
ing, and result in false diagnosis.
• Turning the ESC off does not affect the ABS or brake system operation.
■ESC indicator light (blinks)
■ ESC OFF indicator light (comes on)
CAUTION
Driving with varying tire or wheel
sizes may cause the ESC system tomalfunction. When replacing tires,make sure they are the same size asyour original tires.
WARNING
The Electronic Stability Control sys-
tem is only a driving aid; use pre-
cautions for safe driving by slowing
down on curved, snowy, or icy
roads. Drive slowly and don’t
attempt to accelerate whenever the
ESC indicator light is blinking, or
when the road surface is slippery.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
Drive cautiously and allow extra dis-tance for braking.
Avoid sudden braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle is
stopped.
If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, or other non-slip material under the drive wheels to pro-
vide traction when stalled in ice, snow,
or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to free
it from snow, sand, or mud, first turn the
steering wheel right and left to clear the
area around your front wheels. Then, shift
back and forth between 1st (First) and R
(Reverse) in vehicles equipped with a
manual transaxle or R (Reverse) and any
forward gear in vehicles equipped with an
automatic transaxle. Do not race the
engine, and spin the wheels as little as
possible. If you are still stuck after a few
tries, have the vehicle pulled out by a tow
vehicle to avoid engine overheating and
possible damage to the transaxle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Downshifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
WARNING - ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
CAUTION
Prolonged rocking may causeengine overheating, transaxle dam- age or failure, and tire damage.

What to do in an emergency

7. Place the jack at the front or rear
jacking position closest to the tire
you are changing. Place the jack
at the designated locations under
the frame. The jacking positions
are plates welded to the frame
with two tabs and a raised dot to
index with the jack. 8. Insert the jack handle into the jack
and turn it clockwise, raising the
vehicle until the tire just clears the
ground. This measurement is
approximately 30 mm (1.2 in).
Before removing the wheel lug
nuts, make sure the vehicle is sta-
ble and that there is no chance for
movement or slippage. 9. Loosen the wheel nuts and
remove them with your fingers.
Slide the wheel off the studs and
lay it flat so it cannot roll away. To
put the wheel on the hub, pick up
the spare tire, line up the holes
with the studs and slide the wheel
onto them. If this is difficult, tip the
wheel slightly and get the top hole
in the wheel lined up with the top
stud. Then jiggle the wheel back
and forth until the wheel can be
slid over the other studs.
WARNING- Jack location
To reduce the possibility of
injury, be sure to use only the
jack provided with the vehicle
and in the correct jack position;
never use any other part of the
vehicle for jack support.

Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire. 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.(Continued)
Using tires and wheel other
than the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-
ous accident.
Wheels that do not meet Kia’s specifications may fit poorly
and result in damage to the
vehicle or unusual handling
and poor vehicle control.
The ABS works by comparing the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) (if equipped) to work
irregularly.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling char-
acteristics, ground clearance,
body-to-tire clearance, snow
chain clearance, speedometer
and odometer calibration, head-
light aim and bumper height.

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated fuel is not taken
into the engine. After the engine warms
up during ordinary driving, the PCSV
opens to introduce evaporated fuel to the
engine.
3. Exhaust emission control system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
do not use unauthorized electronic
devices.
Engine exhaust gas precautions(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
WARNING- Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.
