WARNING - Fuel Filling
Fuel may be under pressure.
Always remove the fuel cap
carefully and slowly. If the cap is
venting fuel or if a hissing sound
is heard, wait until the condition
stops before completely
removing the cap. If these
precautions are not followed,
fuel may spray out and cause
serious personal injury.
WARNING
Automotive fuels are flammable/
explosive materials. When
refueling, please note the
following guidelines carefully.
Failure to follow these
guidelines may result in severe
personal injury, severe burns or
death by fire or explosion.
 Before refueling always note
the location of the Emergency
Gasoline Shut-Off, if available,
at the gas station facility.
 Before touching the fuel
nozzle or fuel filler cap, you
should eliminate potentially
dangerous static electricity
discharge by touching
another metal part of the front
of the vehicle, a safe distance
away from the fuel filler neck,
nozzle, or other gas source.
 Do not get back into a vehicle
once you have begun
refueling. Do not touch, rub
or slide against any item or
fabric (polyester, satin, nylon,
etc.) capable of producing
static electricity. Static
electricity discharge can
ignite fuel vapors resulting in
explosion. If you must re-
enter the vehicle, you should
once again eliminate
potentially dangerous static
electricity discharge by
touching a metal part of the
vehicle, away from the fuel
filler neck, nozzle or other
gasoline source.
 When using a portable fuel
container be sure to place the
container on the ground prior
to refueling. Static electricity
discharge from the container
can ignite fuel vapors
causing a fire. Once refueling
has begun, contact with the
vehicle should be maintained
until the filling is complete.
Use only portable fuel
containers designed to carry
and store gasoline.
 Do not use cellular phones
around a gas station or while
refueling any vehicle. Electric
current and/or electronic
interference from cellular
phones can potentially ignite
fuel vapors causing a fire. If
you must use your cellular
phone, use it in a place away
from the gas station.
 When refueling always shut
the engine off. Sparks
produced by electrical
components related to the
engine can ignite fuel vapors
causing a fire.

CHARGING SYSTEM
WARNING
(IF EQUIPPED)This warning light indicates a
malfunction of either the generator or
electrical charging system.
If the warning light illuminates while
driving:
1. Drive to the nearest safe location and
carefully stop your vehicle.
2. With the engine OFF, check the
generator drive belt for looseness or
breakage.
3. If the belt is adjusted properly, a
problem exists somewhere in the
electrical charging system. Have an
Authorized Kia Dealer or other
competent locate and correct the
problem as soon as possible.
ENGINE OIL PRESSURE
WARNING This warning light indicates the engine
oil pressure is low.
If the warning light illuminates while
driving:
1. Drive safely to the side of the road
and stop.
2. With the engine OFF, check the
engine oil level. If the level is low,
add oil as required.
If the warning light remains ON after
adding oil or if oil is not available, call
an Authorized Kia Dealer.
LOW FUEL LEVEL
WARNING This warning light indicates the fuel tank
is near empty. The warning light will
come on when the fuel level has dropped
to about 8.5 L (2.2 US gal.).
Refuel as soon as possible.
4-23

NOTICE
Do not drive the vehicle with a
loose or broken generator belt; the
engine could be damaged by over-
heating because this belt also drives
the water pump.

NOTICE
Do not drive the vehicle when the
Engine Oil Warning Light is ON.
If the engine is not stopped as soon
as possible, severe engine damage
could result.

 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
unnecessarily.
 Slow down when driving on rough
roads.
 For longer tire life and better fuel
economy, 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 and 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 causes the
tires to roll at excessive angles,
which results in faster tire wear. It
takes more power to overcome this
improper alignment, which wastes
fuel.
 Open windows at high speeds can
reduce fuel economy.
 Crosswinds and headwinds reduce
fuel economy. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating
condition is important both for
economy and safety.
Therefore, have an Authorized Kia
Dealer perform scheduled inspections
and maintenance.
DRIVING TIPS

TIRES AND WHEELSTIRE CAREFor proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution
recommended for your vehicle.INFLATION PRESSURESCheck all tire pressures (including the
spare) monthly when the tires are cold.
“Cold tires” means the car has not been
driven for at least three hours or driven
less than one mile (1.6 km).
Recommended pressures must be
maintained to ensure ride quality, vehicle
handling, and minimum tire wear.
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gasing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 120°F (49°C).
Wear eye protection when
checking the battery during
charging.
Disconnect the battery
charger in the following
order.
1. Turn off the battery
charger main switch.
2. Unhook the negative
clamp from the negative
battery terminal.
3. Unhook the positive clamp
from the positive battery
terminal.

NOTICE
• Before performing battery
maintenance or recharging, turn
OFF all accessories and stop the
engine.
• When remounted battery,
disconnect the negative (-)
battery cable first. When re-
installing the battery, reconnect
the negative (-) battery cable
last.

This can be found on the driver side
door.
The correct tire pressure is 210 kPa (30
psi). The compact spare should be at
420kPa (60 psi).
MAINTENANCE
7-26
MMSA7019

NOTICE
• Warm tires normally exceed
recommended cold tire
pressures by 28 to 41 kPa(4 to 6
psi). Do not release air from
warm tires to adjust the
pressure. The tires will become
underinflated when cold.
• Underinflation results in
excessive wear, poor handling,
reduced fuel economy, and the
possibility of blowouts from
overheated tires. Also, low tire
pressure can cause poor sealing
of the tire bead. If the tire
pressure is excessively low,
wheel deformation and/or tire
separation are possible.
Keep tire pressures at the
proper levels. If a tire frequently
needs refilling, have it checked
by an Authorized Kia Dealer or
a tire shop.
• Overinflation produces a harsh
ride, handling problems,
excessive wear at the center of
the tire tread, and a greater
possibility of damage from road
hazards.
WARNING -
Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control.
