Driving tips
SUGGESTIONS FOR ECONOMICAL OPERATIONYour 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
kilometers (miles) you can get from a liter
(gallon) 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:
 Avoid lengthy warm-up idling. Once theengine is running smoothly, begin driv-
ing. Remember, engine warm-up may
take a little longer on cold days.
 Save fuel by accelerating slowly after stopping.
 Keep the engine in tune and follow the recommended periodic maintenance
schedule. This will increase the life of
all parts and lower your operating
costs.
 Do not use the air conditioner unnec- essarily.
 Slow down when driving on rough roads.
 For longer tire life and better fuel econ- omy, always keep the tires inflated to
the recommended pressures.  Maintain a safe distance from other
vehicles to avoid sudden stops. This
will reduce wear on brake linings and
pads. Driving in such a way will also
save fuel because extra fuel is required
to accelerate back to driving speed.
 Do not carry unnecessary weight in the vehicle.
 Do not rest your foot on the brake pedal while driving. This can cause
needless wear, possible damage to the
brakes, and poor fuel economy.
 Improper wheel alignment results in faster tire wear and lower fuel econo-
my.
 Open windows at high speeds can reduce fuel economy.
 Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized Kia
dealer perform scheduled inspections
and maintenance.
WARNING
- Engine off dur- ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect.

Driving tips
When you are ready to leave afterparking on a hill 1. With the automatic transaxle in P (Park), apply your brakes and hold the
brake pedal down while you:
 Start your engine;
 Shift into gear; and
 Release the parking brake.
2. Slowly remove your foot from the brake pedal.
3. Drive slowly forward until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.Maintenance when trailer towing Your vehicle will need service more often
when you regularly pull a trailer.
Important items to pay particular atten-
tion to include engine oil, automatic
transaxle fluid, axle lubricant and cooling
system fluid. Brake condition is another
important item to frequently check. Each
item is covered in this manual, and the
Index will help you find them quickly. If
you’re trailering, it’s a good idea to review
these sections before you start your trip. Don’t forget to also maintain your trailer
and hitch. Follow the maintenance
schedule that accompanied your trailer
and check it periodically. Preferably, con-
duct the check at the start of each day’s
driving. Most importantly, all hitch nuts
and bolts should be tight.
✽ ✽
NOTICE• Due to higher load during trailer
usage, overheating might occur in hot
days or during uphill driving. If the
coolant gauge indicates over-heating,
switch off the A/C and stop the vehicle
in a safe area to cool down the engine.
• When towing check transaxle fluid more frequently.
• If your vehicle is not equipped with the air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
If you do decide to pull a trailerHere are some important points if you
decide to pull a trailer:
 Consider using a sway control. You can
ask a hitch dealer about sway control.
 After your odometer indicates 800 km (500 miles) or more, you can tow a
trailer. For the first 800 km (500 miles)
that you tow a trailer, don’t drive over
80 km/h (50 mph) and don’t make
starts at full throttle. This helps your
engine and other parts of your vehicle
“wear” in at the heavier loads.
 Always drive your vehicle at a moder- ate speed (less than 100 km/h (60
mph)).
 On a long uphill grade, do not exceed 70 km/h (45 mph) or the posted towing
speed limit, whichever is lower.
 The important considerations have to do with weight:
Weight of the trailer
How heavy can a trailer safely be? It
should never weigh more than the maxi-
mum trailer weight with trailer brakes. But
even that can be too heavy. If you feel that
the trailer is adversely affecting the move-
ment of your vehicle, reduce your speed,
avoid uneven or winding roads, avoid
roads with steep grades, and/or lighten
your trailer load.

Maintenance
OWNER MAINTENANCE Owner maintenance schedule The following lists are vehicle checks and
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.When you stop for fuel: Check the engine oil level.
 Check coolant level in coolant reser-voir.
 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 strange 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 automatic transaxle P (Park) function.
 Check parking brake.
 Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
At least monthly: Check coolant level in the coolantrecovery reservoir.
 Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
 Check the inflation pressures of all tires including the spare.At least twice a year (i.e., every Spring and Fall) : Check radiator, heater and air condi- tioning hoses for leaks or damage.
 Check windshield washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
 Check headlight alignment.
 Check muffler, exhaust pipes, shields and clamps.
 Check the lap/shoulder belts for wear and function.
 Check for worn tires and loose wheel lug nuts.
WARNING
- Radiationcoolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns or
other serious injury.
