Driving your vehicle
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 gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to the traffic so you don't have to
change speeds unnecessarily. Avoid
heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary 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 con-
sumption. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption. Keep your vehicle in good condition.
For better fuel economy and reduced
maintenance costs, maintain your vehi-
cle in accordance with the mainte-
nance schedule in section 7. If you
drive your vehicle in severe conditions,
more frequent maintenance is required
(see section 7 for details).
Keep your vehicle clean. For maximum 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 unnecessary 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.

Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽
NOTICE
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 forget to
check both the engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
WARNING
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.
Always check the tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
vehicle. For further information
and tread limits, refer to “Tires
and wheels” in section 7.

Driving your vehicle
Severe weather conditions in the winter
result in greater wear and other prob-
lems. To minimize the problems of winter
driving, you should follow these sugges-
tions:
Snowy or Icy conditions
To drive your vehicle in deep snow, it may
be necessary to use snow tires on your
tires. If snow tires are needed, it is nec-
essary to select tires equivalent in size
and type of the original equipment tires.
Failure to do so may adversely affect the
safety and handling of your vehicle.
Furthermore, speeding, rapid accelera-
tion, sudden brake applications, and
sharp turns are potentially very haz-
ardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake appli-
cations on snowy or icy roads may cause
skids to occur. You need to keep suffi-
cient distance between the vehicle in
operation in front and your vehicle. Also,
apply the brake gently.
Snow tires
If you mount snow tires on your vehicle,
make sure they are radial tires of the
same size and load range as the original
tires. Mount snow tires on all four wheels
to balance your vehicle’s handling in all
weather conditions. Keep in mind that the
traction provided by snow tires on dry
roads may not be as high as your vehi-
cle's original equipment tires. You should
drive cautiously even when the roads are
clear. Check with the tire dealer for max-
imum speed recommendations.
Do not install studded tires without firstchecking local, state and municipal regu- lations for possible restrictions againsttheir use.
WINTER DRIVING
WARNING- Snow tire size
Snow tires should be equivalent in
size and type to the vehicle's stan-
dard tires. Otherwise, the safety
and handling of your vehicle may
be adversely affected.

Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized Kia dealer
or a service station.
Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized Kia dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
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
heated 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 instructions on the con-
tainer. Window washer 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
finish.
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 temporar-
ily while you put the shift lever in P (auto-
matic transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.

What to do in an emergency
3. Have all passengers get out of thevehicle. 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 sec-
tion.
If engine stalls while driving
1. Reduce your speed gradually, keeping a straight line. Move cautiously 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.
If the engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransaxle, be sure the shift lever is in N
(Neutral) or P (Park) and the emer-
gency 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 operate the
starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
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 fuel level.
2. With the ignition switch in the LOCKposition, check all connectors at the
ignition coil and spark plugs.
Reconnect any that may be discon-
nected or loose.
3. Check the fuel line in the engine com- partment.
4. If the engine still does not start, call an authorized Kia dealer or seek other
qualified assistance.
IF THE ENGINE WILL NOT START
WARNING
If the engine will not start, do not
push or pull the vehicle to start it.
This could result in a collision or
cause other damage. In addition,
push or pull starting may cause the
catalytic converter to overload and
create a fire hazard.

What to do in an emergency
Jump starting procedure
1. Make sure the booster battery is 12-volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles to
touch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration.
First connect one end of a jumper
cable to the positive terminal of the
discharged battery (1), then connect
the other end to the positive terminal
on the booster battery (2).
Proceed to connect one end of the
other jumper cable to the negative ter-
minal of the booster battery (3), then
the other end to a solid, stationary,
metallic point (for example, the engine
lifting bracket) away from the battery
(4). Do not connect it to or near any
part that moves when the engine is
cranked. Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery when making
connections.
5. Start the engine of the vehicle with the booster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging isnot apparent, you should have your vehi-cle checked by an authorized Kia dealer.
Push-starting
Your manual transaxle-equipped vehicle
should not be push-started because it
might damage the emission control sys-
tem.
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this section for
jump-starting.
WARNING
Never tow a vehicle to start it
because the sudden surge forward
when the engine starts could cause
a collision with the tow vehicle.
CAUTION- Battery cables
Do not connect the jumper cablefrom the negative terminal of thebooster battery to the negative ter-minal of the discharged battery.This can cause the discharged bat-tery to overheat and crack, releas- ing battery acid.

66
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking,
the engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as itis safe to do so.
2. Place the shift lever in P (automatic transaxle) or neutral (manual
transaxle) and set the parking brake. If
the air conditioning is on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from underneath the hood, stop the
engine. Do not open the hood until the
coolant has stopped running or the
steaming has stopped. If there is no
visible loss of engine coolant and no
steam, leave the engine running and
check to be sure the engine cooling
fan is operating. If the fan is not run-
ning, turn the engine off.
4. Check to see if the water pump drive belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop). 5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized Kia dealer for
assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, call an author-
ized Kia dealer for assistance.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling systemand this should be checked as soonas possible by an authorized Kiadealer.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.

inspections that should be performed by
the owner or an authorized Kia dealer at
the frequencies indicated to help ensure
safe, dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties 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 steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling 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 oper- ation of your transaxle occurs, check
the transaxle fluid level.
Check the automatic transaxle P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
WARNING
