Driving your vehicle
The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 20 mph (30
km/h).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. Keep the cruise control system
off (CRUISE indicator light OFF)
when the cruise control is not in use,
to avoid inadvertently setting a speed.Use the cruise control system only
when traveling on open highways in
good weather.
Do not use the cruise control when
driving in heavy or varying traffic, or
on slippery (rainy, icy or snow-cov-
ered) or winding roads or over 6%
up-hill or down-hill roads.
✽ ✽
NOTICE
• During normal cruise control oper-
ation, when the SET switch is acti-
vated or reactivated after applying
the brakes, the cruise control will
activate after approximately 3 sec-
onds. This delay is normal.
• To activate cruise control, depress the brake pedal at least once after
turning the ignition switch to the
ON position or starting the engine.
This is to check if the brake switch
which is important part to cancel
cruise control is in normal condi-
tion.
CRUISE CONTROL SYSTEM
WARNING - Misuse of
Cruise Control
Do not use cruise control if the
traffic situation does not allow
you to drive safely at a constant
speed and with sufficient dis-
tance to the vehicle in front.

Your vehicle's fuel economy depends
mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 7 for details).
Keep your vehicle clean. For maxi- mum service, your vehicle should
be kept clean and free of corrosive
materials. It is especially important
that mud, dirt, ice, etc. not be
allowed to accumulate on the
underside of the vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.

Driving your vehicle
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized Kia dealer and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Don’t let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear shift lever in P
(Park, Automatic transmission/Dual
clutch transmission) and block the
rear wheels so the vehicle cannot
roll. Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
vehicle to be sure the movement of
the front wheels and the steering
components are not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tow straps or chains, flash-
light, emergency flares, sand, shov-
el, jumper cables, window scraper,
gloves, ground cloth, coveralls, blan-
ket, etc.
TRAILER TOWING
We do not recommend using this
vehicle for trailer towing.

What to do in an emergency
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
If you have a flat tire while
driving
If a tire goes flat while you are driv-
ing:
1. Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause a loss of con-
trol. When the vehicle has slowed
to such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes. 2. When the vehicle is stopped, turn
on your emergency hazard flash-
ers, set the parking brake and put
the transmission in P (for
Automatic transmission / Dual
clutch transmission).
3. Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
4. When changing a flat tire, follow the instruction provided later in
this section.
If the engine stalls while driv-
ing
1. Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, contact
an authorized Kia dealer or seek
other qualified assistance.
✽ ✽NOTICE
If there was a check engine light and
loss of power or stall and if safe to do
so, wait at least 10 seconds to restart
the vehicle after it stalls. This may
reset the car so it will no longer run
at low power (limp home) condition.

IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransmission / dual clutch trans-
mission, be sure the shift lever is
in N (Neutral) or P (Park) and the
emergency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you oper-
ate the starter, the battery is dis-
charged.
4. Check the starter connections to be sure they are securely tight-
ened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1. Check the fuel level.
2. With the ignition switch in theLOCK position, check all connec-
tors at the ignition coils and spark
plugs. Reconnect any that may be
disconnected or loose.
3. Check the fuel line in the engine compartment.
4. If the engine still does not start, call an authorized Kia dealer or
seek other qualified assistance.
WARNING - Push/
pull start
Do not push or pull the vehicle
to start it. Push or pull starting
may cause the catalytic con-
verter to overload and create a
fire hazard.

ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or “pulls” to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmis- sion/dual clutch transmission P
(Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
