Driving your vehicle
Disc brakes wear indicator Your vehicle has disc brakes.
When your brake pads are worn and it's
time for new pads, you will hear a high-
pitched warning sound from your front
brakes or rear brakes (if equipped). You
may hear this sound come and go or it
may occur whenever you depress the
brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
✽ ✽NOTICETo avoid costly brake repairs, do not
continue to drive with worn brake pads.
Power adjustable pedals
(if equipped)To adjust the position of the accelerator
and brake pedals, turn the ignition key to
the “ON” position with the selector lever
in the "P" position and push the switch.
If you push the “” portion of the switch,
the pedals move rearward.
If you push the “” portion of the switch,
the pedals move forward.
WARNING
- Brake wear
This brake wear warning sound
means your vehicle needs service.
If you ignore this audible warning,
you will eventually lose braking per-
formance, which could lead to a
serious accident.
CAUTION
Always replace brake pads as com-
plete front or rear axle sets toensure smooth brake performance.

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.

7Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended amount.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.
Tire rotation To equalize tread wear, it is recom-
mended that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
Refer to Section 8, Specifications.
Disc brake pads should be inspected
for wear whenever tires are rotated.Rotate radial tires that have an
asymmetric tread pattern only
from front to rear and not from
right to left.

WARNING
 Do not use the temporary
spare tire for tire rotation
 Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics that could result in death,
severe injury, or property
damage.
