Knowing your vehicle
If there is no passenger in the front pas-
senger seat or if the passenger in the
front passenger's seat is very small (such
as a child), the front PASSENGER AIR
BAG OFF indicator may go ON.
When this indicator is ON, the front pas-
senger's air bag will not deploy.
The side air bag will not deploy if the front
seat is unoccupied.
The side air bag may deploy if the front
seat is occupied by a small occupant.
Main components of occupant
classification systemA detection device located within the
front passenger seat cushion.
 Electronic system to determine
whether passenger air bag systems
(both front and side) should be activat-
ed or deactivated.
 A warning light located on the instru-
ment panel which illuminates the
words “PASSENGER AIR BAG OFF”
indicating the front passenger air bag
system is deactivated.
 The instrument panel air bag warning
light is interconnected with the occu-
pant classification system. Always be sure that you and all vehicle
occupants are seated and restrained
properly (sitting upright with the seat in
an upright position, centered on the seat
cushion, with the person’
s legs comfort-
ably extended, feet on the floor, and
wearing the safety belt properly) for the
most effective protection by the air bag
and the safety belt.
 The OCS may not function properly if
the passenger takes actions which can
defeat the detection system. These
include:
(1) Failing to sit in an upright position.
(2) Leaning against the door or center console.
(3) Sitting towards the sides or the front of the seat.
(4) Putting legs on the dashboard or rest- ing them on other locations which
reduce the passenger weight on the
front seat.
(5) Improperly wearing the safety belt.
(6) Reclining the seat back.

CAUTION
If the occupant classification sys-tem is not working properly, the airbag warning light ( ) on theinstrument panel will illuminate because the passenger’s air bag isconnected with the occupant clas-sification system. If there is a mal- function of the occupant classifica-tion system, the "Passenger Air bagOff" indicator will not illuminate and the front passenger's air bag willdeploy in frontal crashes even ifthere is child or no occupant in the front passenger's seat.
Have an authorized Kia dealerinspect the occupant classification system with the SRS air bag systemas soon as possible if any of follow- ing occur;
 The SRS air bag warning light does not illuminate when the igni-tion key is turned to "ON" posi-tion.
 The SRS air bag warning light remains illuminated after illumi-nating or blinking for approxi- mately 6 seconds.
 The SRS air bag warning light illu- minates while the vehicle is beingdriven.
AIR
BAG
WARNING
 The occupant classification sys-
tem can function only when the
ignition key is in the "ON" posi-
tion.
 If a very low weight adult is seat- ed in the front passenger seat, the
occupant classification system
may or may not turn off the right
front passenger air bag, depend-
ing upon the person's seating
position and body type. Everyone
in your vehicle should wear a
safety belt properly -- whether or
not there is an air bag for that per-
son.
 If the front seat passenger changes their seating position
(for example, by not sitting
upright, by sitting on the edge of
the seat, or by otherwise being
out of position), the "Passenger
Air bag Off" indicator may be
turned on, and the passenger's air
bag may not deploy in a collision.
Always be sure to sit properly in
the front passenger’s seat and
wear the safety belt properly and
do not do any of the following.
(Continued)
WARNING
- Children in rear
seat
Even though your vehicle is
equipped with the occupant classi-
fication system, children aged 12
and under should be seated in the
rear seats. Do not install a child
restraint system in the front pas-
senger’s seat since a child restraint
may result in an improper reading
by the occupant classification sen-
sor. The infant/child could be
severely injured or killed by an air
bag deployment in case of an acci-
dent.
Children are afforded the most pro-
tection in the event of an accident
when they are restrained by the
proper restraint system in the rear
seat.

Driving your vehicle
Moving up a steep grade from a
standing startTo move up a steep grade from a stand-
ing start, depress the brake pedal, shift
the shift lever to D (Drive). Select the
appropriate gear depending on load
weight and steepness of the grade, and
release the parking brake. Depress the
accelerator gradually while releasing the
service brakes.
When accelerating from a stop on a
steep hill, the vehicle may have a ten-
dency to roll backwards. Shifting the
shift lever into 2 (Second Gear) while
in Sport mode will help prevent the
vehicle from rolling backwards.Ignition key interlock systemThe ignition key cannot be removed
unless the shift lever is in the P (Park)
position. If the ignition switch is in any
other position, the key cannot be
removed.
Shift lock systemFor your safety, the Automatic Transaxle
has a shift lock system which prevents
shifting the transaxle out of P (Park)
unless the brake pedal is depressed.
To shift the transaxle out of P (Park):
1. Depress and hold the brake pedal.
2. Start the engine or turn the ignition tothe ON position.
3. Move the shift lever.
If the brake pedal is repeatedly
depressed and released with the shift
lever in the P (Park) position, a chattering
sound near the shift lever may be heard.
This is a normal condition.
Shift-lock overrideIf the shift lever should fail to move from
the P (Park) position with the brake pedal
depressed, continue depressing the
brake, then do the following:
1. Carefully remove the cap covering the S/Lock override access hole which is
located on the right side of the shift
lever.
2. Insert the screwdriver into the access hole and press down on the key.
3. Depress the lock release button and move the shift lever.
4. Have your vehicle inspected by an authorized Kia dealership immediately.

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.

TRAILER TOWING✽
✽NOTICE
Pulling a trailer improperly can damage
your vehicle and result in costly repairs
not covered by your warranty. To identify what the vehicle trailering
capacity is for your vehicle, you should
refer to the chart on this page. Remember that trailering is different than
just driving your vehicle by itself.
Trailering causes major changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires cor-
rect equipment, and cautious driving.
This section contains many time-tested,
important trailering tips and safety rules.
Many of these are important for your
safety and that of your passengers.
Please read this section carefully before
you pull a trailer.
WARNING
- Towing a trail-
er
If you don't use the correct equip-
ment or you drive improperly, you
can lose control when you pull a
trailer. For example, if the trailer is
too heavy, the brakes may fail, and
would at least be ineffective to
promptly stop the vehicle. You and
your passengers could be seriously
or fatally injured. Pull a trailer only if
you have followed all the steps in
this section.
WARNING
- Weight limits
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, gross
axle weight and trailer tongue load
are all within the limits.

Driving tips10
5Load-pulling components such as the
engine, transaxle, wheel assemblies, and
tires are forced to work harder against
the load of the added weight. The engine
is required to operate at relatively higher
speeds and under greater loads. This
additional burden generates extra heat
which creates more wear in engine, and
a shortened engine life. The trailer also
adds considerably to wind resistance,
increasing the pulling requirements.Hitches It's important to have the correct hitch
equipment. Crosswinds, large trucks
going by, and rough roads are a few rea-
sons why you’ll need the right hitch. Here
are some rules to follow:
 Do not attach a trailer hitch which
requires you to alter other parts on
your vehicle.
 Never make a hole in your vehicle to accommodate a hitch.
 The bumpers on your vehicle are not intended for hitches. Do not attach
rental hitches or other bumper-type
hitches to them. Use only a frame-
mounted hitch that does not attach to
the bumper.
Safety chains You should always attach chains
between your vehicle and your trailer.
Cross the safety chains under the tongue
of the trailer so that the tongue will not
drop to the road if it becomes separated
from the hitch.
Instructions about safety chains may be
provided by the hitch manufacturer or by
the trailer manufacturer. Follow the man-
ufacturer’s recommendation for attaching
safety chains. Always leave just enough
slack so you can turn with your trailer.
And, never allow safety chains to drag on
the ground.
Trailer brakes If your trailer weighs more than the max-
imum weight for a trailer without brakes,
then the trailer needs its own brakes. You
must consult with a knowledgeable and
reputabel trailer vendor to determine
which brake equipped trailer is right for
your needs. Be sure to read and follow
the instructions for the trailer brakes so
you’ll be able to install, adjust and main-
tain them properly.
WARNING
If you damage the body of your car,
installing, or using a trailer hitch,
you must have any resulting hole
immediately repaired, An unsealed
hole can allow deadly carbon
monoxide (CO) from your exhaust
into your vehicle.
WARNING
- Trailer brakes
Do not use a trailer with its own
brakes unless you are absolutely
certain that you have properly set
up the brake system pursuant to
the trailer manufacture’s instruc-
tions. This is not a task for ama-
teurs. Use an experienced, compe-
tent trailer shop for this work.
WARNING
- Trailer andvehicle brakes
NEVER connect or allow anyone
else to connect your vehicle’s
brakes to any trailer brake system.
Altering your vehicle’s brakes could
result in total brake failure.

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.

Driving tips14
5Weight of the trailer tongue
The tongue load of any trailer is an
important weight to measure because it
affects the total gross vehicle weight
(GVW) of your vehicle since that is the
trailer weight pushing down on the hitch
on your vehicle. The rest of the trailer
weight is sitting on the trailer’s wheels.
The trailer tongue should weigh a maxi-
mum of 10% of the total loaded trailer
weight. After you've loaded the trailer, go
to a Weigh Station and weigh the trailer
and then the tongue, separately, to see if
the weights are proper. If they aren’t, you
may be able to correct them simply by
moving some items around in the trailer.
WARNING -
Trailer balance
 Never load a trailer with more
weight in the rear than in the
front. The front should be loaded
with approximately 60% of the
total trailer load; the rear should
be loaded with approximately
40% of the total trailer load.
 Never exceed the maximum weight limits of the trailer or trail-
er towing equipment. Improper
loading can result in excessive
personal injury. Check weights
and loading at a commercial
scale or highway patrol office
equipped with scales.
 An improperly loaded trailer can cause loss of vehicle control.
WARNING
- Vehicle weight
The gross axle weight rating
(GAWR) and the gross vehicle
weight rating (GVWR) for your vehi-
cle are on the manufacturer's label
attached to the driver's door.
Exceeding these ratings can cause
an accident or vehicle damage. You
can calculate the weight of your
load by weighing the items (and
people) before putting them in the
vehicle. Be careful not to overload
your vehicle.

7TIRES AND WHEELS
Tire care For 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.Recommended cold tire infla-
tion pressures All tire pressures (including the
spare) should be checked every day
when the tires are cold. “Cold Tires”
means the vehicle has not been driv-
en for at least three hours or driven
less than 1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING -
Tire underin-
flation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for protracted periods at high
speeds.

Maintenance
Tire replacementIf the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1.6 mm (1/16 inch) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
Compact spare tire replace-
ment (if equipped)A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new Kia and should be mounted on
the same compact spare tire wheel.
The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
Wheel alignment and tire
balance The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.✽ ✽NOTICEImproper wheel weights can dam-
age your vehicle's aluminum wheels.
Use only approved wheel weights.
