Safety features of your vehicle
Problems may arise if the sensor
installation angles are changed due
to the deformation of the front
bumper, body or B pillar where side
collision sensors are installed. Have
the vehicle checked and repaired by
an authorized Kia dealer.
Installing aftermarket bumper guards
or replacing a bumper with non-gen-
uine parts may adversely affect your
vehicle’s collision and air bag deploy-
ment performance.Air bag inflation conditions
Front air bags
Front air bags are designed to inflate
in a frontal collision depending on
the intensity, speed or angles of
impact of the front collision.
WARNING - Air bag sensors
Do not hit or allow any objects to impact the locations where
air bag or sensors are installed.
This may cause unexpected
air bag deployment, which
could result in serious per-
sonal injury or death.
If the installation location or angle of the sensors is altered
in any way, the air bags may
deploy when they should not
or they may not deploy when
they should.
Therefore, do not try to per-
form maintenance on or
around the air bag sensors.
Have the vehicle checked and
repaired by an authorized Kia
dealer.

Safety features of your vehicle
SRS Care
The SRS is virtually maintenance-free
and there are no parts you can safely
service by yourself. If the SRS air bag
warning light does not illuminate, or
continuously remains on, have your
vehicle immediately inspected by an
authorized Kia dealer.
Any work on the SRS system, such
as removing, installing, repairing, or
any work on the steering wheel must
be performed by an authorized Kia
dealer. Improper handling of the SRS
system may result in serious person-
al injury.
For cleaning the air bag pad covers,
use only a soft, dry cloth or one
which has been moistened with plain
water. Solvents or cleaners could
adversely affect the air bag covers
and proper deployment of the sys-
tem.If components of the air bag system
must be discarded, or if the vehicle
must be scrapped, certain safety
precautions must be observed. An
authorized Kia dealer knows these
precautions and can give you the
necessary information. Failure to fol-
low these precautions and proce-
dures could increase the risk of per-
sonal injury.
Adding equipment to or modi-
fying your air bag-equipped
vehicle
If you modify your vehicle by chang-
ing your vehicle's frame, bumper sys-
tem, front end or side sheet metal or
ride height, this may affect the opera-
tion of your vehicle's air bag system.
WARNING - Tampering
with SRS
Do not tamper with or discon-
nect SRS wiring, or other compo-
nents of the SRS system. Doing
so could result in the accidental
inflation of the air bags or by ren-
dering the SRS inoperative.

Features of your vehicle
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
and other pollutants that come into
the vehicle from the outside through
the heating and air conditioning sys-
tem. If dust or other pollutants accu-
mulate in the filter over a period of
time, the air flow from the air vents
may decrease, resulting in moisture
accumulation on the inside of the
windshield even when the outside
(fresh) air position is selected. If this
happens, have the climate control air
filter replaced by an authorized Kia
dealer.
✽ ✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty,
rough roads, more frequent cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized Kia
dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.
The air conditioning system should
be serviced by an authorized Kia
dealer.
CAUTION - Compressor
damage
It is important that the correct
type and amount of oil andrefrigerant is used. Otherwise,damage to the compressor andabnormal system operation mayoccur.

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 inspections
Fluid levels, such as engine oil,
engine coolant, brake fluid, and
washer fluid should be checked on a
regular basis, with the exact interval
depending on the fluid. Further
details are provided in chapter 7,
“Maintenance”.
Before starting
Close and lock all doors.
Position the seat so that all con-trols are easily reached.
Buckle your seat belt.
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 off.

familiar with your vehicle and its
equipment.
BEFORE DRIVING
WARNING - Distracted driving
Driving while distracted can
result in a loss of vehicle con-
trol that may lead to an acci-
dent, severe personal injury and
death. The driver's primary
responsibility is in the safe and
legal operation of the vehicle.
Use of any hand held devices,
other equipment or vehicle sys-
tems that distract the driver
should not be used during vehi-
cle operation.

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 gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at amoderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary 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 consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 7 for details).
Keep your vehicle clean. For maxi- mum 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 unneces- sary 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.

Use high quality ethylene gly-
col 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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 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 battery and cables as described
in chapter 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
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and igni-
tion system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components 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 heat-
ed 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 instruc-
tions on the container. Window wash-
er 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 fin-
ish.
