KNOWING YOUR VEHICLE
3-50
AIR BAG WARNING LIGHTThe purpose of the air bag warning light
in your instrument panel is to alert you of
a potential problem with your Air Bag -
Supplemental Restraint System (SRS).
Have the system checked if:
• The light does not illuminate when
you turn the ignition ON.
• The light stays ON after the engine
starts.
• The light comes ON or flashes while
you are driving.
SUPPLEMENTAL RESTRAINT
SYSTEM SERVICEYour Supplemental Restraint System is
virtually maintenance-free. There are no
parts which you can service.
You must have the system serviced
under the following circumstances:
• If an air bag ever inflates, the air bag
must be replaced. Do not try to
remove or discard the air bag by
yourself.
This must be done by an Authorized
Kia Dealer.
• If the air bag warning indicator light
alerts you of a problem, have the air
bag system checked as soon as
possible. Otherwise, your air bag
might not inflate when you need it.
The entire SRS system must be inspected
by an authorized Kia dealer 10 years
after the vehicle manufacture date.
AIR BAG WARNING LIGHT
AIR
BAG
AS2B03035
 Do not use excessive force
on the side of the seat.
 Do not place any objects
over the airbag or between
the airbag and yourself.
 Do not place any objects (an
umbrella, bag,etc.) between
the front door and the front
seat. Such objects may
become dangerous projectiles
and cause injury if the side air
bag inflates.
 To prevent unexpected
deploy-ment of the side air
bag that may result in
personal injury, avoid impact
to the side airbag sensor
when the ignition key is
“ON”.

DRIVING TIPS
5-4 Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
 Do not misuse or abuse the engine.
Examples of misuse are coasting
with the ignition off and descending
steep grades in gear with the ignition
off.
 Do not operate the engine at high idle
speed for extended periods (5
minutes or more).
 Do not modify or tamper with any
part of the engine or emission control
system. All inspections and
adjustments must be made by a
qualified technician.
Failure to observe the above precautions
could result in damage to the catalytic
converter and to your vehicle and could
void your warranties.
BEFORE DRIVINGBefore entering vehicle:
 Be sure that all windows, outside
mirror(s), and outside lights are clean.
 Check the condition of the tires.
 Check under the vehicle for any sign
of leaks.
 Be sure there are no obstacles behind
you if you intend to back up.NECESSARY
INSPECTIONSFluid levels, such as engine oil, engine
coolant, brake/clutch fluid, and washer
fluid should be checked on a regular
basis, with the exact interval depending
on the fluid. Further details are provided
in Maintenance, Section 7.
BEFORE STARTING Close and lock all doors.
 Position the seat so that all controls
are easily reached.
 Adjust the inside and outside
rearview mirrors.
 Be sure that all lights work.
 Check all gauges.
 Check the operation of warning
lights when the ignition switch is
turned to the ON position.
 Release the parking brake and make
sure the brake warning light goes out.
For safe operation, be sure you are
familiar with your vehicle and its
equipment.
MS-CNA-Eng 5 New.qxd 7/25/2005 5:21 PM Page 4

 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

WARNING - Engine OFF
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 without the engine
running. Instead, downshift to
any appropriate gear for engine
braking effect.
