CRUISE CONTROL
(IF EQUIPPED)The cruise control system provides
automatic speed control for your comfort
when driving on freeways, tollroads, or
other noncongested highways. This
system is designed to function above
approximately 25 mph (40 km/h).
TO SET THE CRUISE1. Push in the cruise control main
switch. This turns the system on.
2. Accelerate to the desired cruising
speed above 25 mph (40 km/h).
3. Push the "COAST/SET" control
switch and release it. The "CRUISE"
indicator light in the instrument
cluster will illuminate after you have
set the vehicle to the desired speed.
4. Remove your foot from the
accelerator pedal and the desired
speed will automatically be
maintained.5. To increase speed, temporarily
depress the accelerator pedal enough
for the vehicle to exceed the preset
speed. When you remove your foot
from the accelerator pedal, the
vehicle will return to the speed you
have set.
TO CANCEL THE CRUISE
SPEEDDo one of the followings:
• Depress the brake pedal.
• Depress the clutch pedal (Manual
transaxle).
• Shift the shift lever to the “N”
position (Automatic transaxle).
• Decrease the vehicle speed 12mph
(20 km/h) lower than memorized
speed.
• Decrease the vehicle speed to less
than approximately 25 mph (40
km/h).
• Release the main switch.

TCS ON/OFF MODEIn the TCS ON mode, the indicator in the
instrument cluster will not be illuminated.
The indicator will illuminate when the
ignition key is turned to the “ON”
position, but it should go off after 3
seconds. It means the TCS is in the stand-
by status and at the moment of the actual
operation of the TCS, the indicator will
blink.
To switch to TCS OFF mode, press the
TCS switch. System will be deactivated
and the TCS indicator in the instrument
cluster will illuminate.
If the TCS indicator stays on in the TCS
ON mode, take your car to your
Authorized Kia Dealer and have the
system checked.
✻
NOTICE
• The TCS ON mode is activated
automatically when the engine is
started.
 When the TCS is operating
properly, you may feel a slight
pulsation in the vehicle. This is
only the effect of brake control
and is not unusual.
 When the engine starts, your
may hear a “click” sound from
the engine compartment. This is
only the sound of the TCS being
checked.
 When moving out of mud or
fresh snow with the TCS ON,
pressing the accelerator pedal
may not cause the engine speed
to increase.

DRIVING TIPS
5-4 Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
 Do not misuse or abuse the engine.
Examples of misuse are coasting
with the ignition off and descending
steep grades in gear with the ignition
off.
 Do not operate the engine at high idle
speed for extended periods (5
minutes or more).
 Do not modify or tamper with any
part of the engine or emission control
system. All inspections and
adjustments must be made by a
qualified technician.
Failure to observe the above precautions
could result in damage to the catalytic
converter and to your vehicle and could
void your warranties.
BEFORE DRIVINGBefore entering vehicle:
 Be sure that all windows, outside
mirror(s), and outside lights are clean.
 Check the condition of the tires.
 Check under the vehicle for any sign
of leaks.
 Be sure there are no obstacles behind
you if you intend to back up.NECESSARY
INSPECTIONSFluid levels, such as engine oil, engine
coolant, brake/clutch fluid, and washer
fluid should be checked on a regular
basis, with the exact interval depending
on the fluid. Further details are provided
in Maintenance, Section 7.
BEFORE STARTING Close and lock all doors.
 Position the seat so that all controls
are easily reached.
 Adjust the inside and outside
rearview mirrors.
 Be sure that all lights work.
 Check all gauges.
 Check the operation of warning
lights when the ignition switch is
turned to the ON position.
 Release the parking brake and make
sure the brake warning light goes out.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.

DRIVING TIPS
5-8
DRIVING AT NIGHTBecause night driving presents many
more hazards than driving in the
daylight, here are some important tips to
remember:
 Slow down and keep more distance
between you and other vehicles as it
may be more difficult to see at night,
especially in rural areas where there
may not be any street lights.
 Adjust your mirrors to reduce the
glare from other driver’s headlights.
 Keep your headlights clean and
properly aimed. Dirty or misaimed
headlights will make it much more
difficult to see at night.
 Avoid staring directly at the
headlights of oncoming vehicles.
You could be temporarily blinded
and it will take several seconds for
your eyes to readjust to the darkness.
DRIVING IN THE RAINRain and wet roads can make driving
dangerous, especially if you’re not
prepared for the slick pavement. Here are
a few things to consider when driving in
the rain:
 Be sure your windshield wipers are
in good condition.
 A heavy rainfall will make it harder
to see and will increase the distance
needed to stop your vehicle, so slow
down.
 If your tires aren’t in good condition,
making a quick stop on wet
pavement can cause a skid and
possibly lead to an accident. Be sure
your tires and windshield wipers are
in good shape.
 Turn on your headlights to make it
easier for others to see you.
 Driving too fast through large
puddles can affect your brakes. If
you must go through puddles, try to
drive through them slowly.
WARNING -
Spinning
Tires
Do not spin the wheels
especially at speeds more than
35 mph (56 km/h). Spinning the
wheels at high speeds when the
vehicle is stationary could
cause a tire to overheat,
explode and injure by standers.

5-9
 If you believe you may have gottenyour brakes wet, apply them lightly
while driving until normal braking
operation returns.WINTER DRIVING We recommend that you carryemergency equipment. Some things
you might include are tire chains, a
window scraper, windshield de-icer,
a bag of sand or salt, flares, a small
shovel and jumper cables.
 Make sure you have sufficient ethylene glycol coolant in the
radiator.
 Check the battery condition and cables. Cold temperatures reduce the
capacity of any battery, so it must be
in top shape to provide enough
winter starting power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.  Use antifreeze-formulated windshield
washer fluid and make sure you have
sufficient fluid for your trip. (Do not
use engine coolant antifreeze.)
 Do not use the parking brake if it might freeze. This is most likely to
happen after driving in slushy or wet
conditions and temperatures drop into
the freezing range. When parking,
shift to P (Park) with automatic
transaxle, or to 1 (First) or R
(Reverse) with a manual transaxle
and block the rear wheels.
SNOW TIRESWhen snow tires are used, select the size
and construction specified on the Tire
Pressure Label. It is strongly
recommended that snow tires be used on
all four wheels, or poor handling may
result. Snow tires should not be operated
at speeds exceeding 120 km/h (75 mph).
These tires should be inflated 4 psi (28
kPa, 0.3 kg/cm
2) above the recommended pressures shown on the Tire
Specification/Pressure Label, but inflation
should never exceed the maximum cold-
tire pressure shown on the tire sidewalls.
Do not install studded tires without first
checking local, provincial and municipal
regulations for possible restrictions
against their use.
WARNING - Snow Tire
Size
Snow tires should be
equivalent in size and type to
the vehicle’s standard tires.
Otherwise, the safety and
handling of your vehicle may be
adversely affected.

ROAD WARNINGHAZARD WARNING FLASHERThe hazard warning flasher serves as a
warning to other drivers to exercise
extreme caution when approaching,
overtaking, or passing your vehicle. It
should be used whenever emergency
repairs are being made or when the vehicle
is stopped near the edge of a roadway.Depress the flasher switch with the
ignition switch in any position.
All turn signal lights will flash
simultaneously.
• The hazard warning flasher will
operate whether your vehicle is
running or not.
 The turn signals do not operate when
the hazard flasher is on.
 Care must be taken when using the
hazard warning flasher while the
vehicle is being towed. Local
regulations may prohibit using it in
this manner.
OVERHEATINGIf your temperature gauge indicates
overheating, if you experience a loss of
power, or if you hear a loud knocking or
pinging noise, the engine has probably
overheated. You should follow these
procedures if you experience any of
these symptoms.
1. Turn the hazard warning flasher on,
then drive to the nearest safe location
and stop your vehicle; set the
automatic transaxle in P (Park), or
shift the manual transaxle to neutral
and apply the parking brake.
2. Make sure the air conditioner is off.
3. If coolant or steam is boiling out of
the radiator, stop the engine, then
turn the ignition switch to the ON
position. Do not restart the engine.
The radiator cooling fan will
automatically operate with the
ignition switch in the ON position. If
the cooling fan does not operate, call
an Authorized Kia Dealer for

MAINTENANCE
7-38When choosing an oil, consider the range
of temperature your vehicle will be
operated in before the next oil change.
Then select the recommended oil
viscosity from the chart.EXTERIOR CAREEXTERIOR GENERAL
CAUTIONIt is very important to follow the
manufacturer’s directions when using
any chemical cleaner or polish. Read all
warning and caution statements that
appear on the label.FINISH MAINTENANCE
WASHINGTo help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
special attention to the removal of any
accumulation of salt, dirt, mud, or other
foreign materials. Make sure the drainholes in the lower edges of the doors and
rocker panels are kept clear and clean.
Insects, tar, tree sap, bird droppings,
industrial fallout and similar deposits can
damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, can be used.
After washing, rinse the vehicle
thoroughly with lukewarm or cold water.
Do not allow soap to dry on the finish.
WAXINGWax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim as well,
to protect it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.
✻
NOTICE
Do not use strong soap, chemical
detergents or hot water, and do not
wash the vehicle in direct sunlight
or when the body of the vehicle is
warm.
CAUTION
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired,
dry the brakes by applying them
lightly while maintaining a slow
forward speed.
