Safety features of your vehicle
The air bag modules are located
both in the center of the steering
wheel and in the front passenger's
panel above the glove box. When the
SRSCM detects a sufficiently severe
impact to the front of the vehicle, it
will automatically deploy the front air
bags.Upon deployment, tear seams mold-
ed directly into the pad covers will
separate under pressure from the
expansion of the air bags. Further
opening of the covers then allows full
inflation of the air bags.
A fully inflated air bag, in combina-
tion with a properly worn seat belt,
slows the driver's or the passenger's
forward motion, reducing the risk of
head and chest injury.
After complete inflation, the air bag
immediately starts deflating,
enabling the driver to maintain for-
ward visibility and the ability to steer
or operate other controls.

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.

Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine
oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.
WARNING - Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out
tires should be replaced as
soon as possible. For further
information and tread limits,
refer to "Tires and wheels" in
chapter 7.
WARNING- Under/Over Inflated Tires
Always check the tires for prop-
er inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.

To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly. Check
the inflation pressures as soon as
possible after installing the spare
tire. Adjust it to the specified pres-
sure, if necessary. Refer to “Tires
and wheels” in chapter 8.
Important - use of compact spare
tire (if equipped)
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.
You should drive carefully when the compact spare is in use. The
compact spare should be replaced
by the proper conventional tire and
rim at the first opportunity.
The operation of this vehicle is not recommended with more than one
compact spare tire in use at the
same time. The compact spare should be inflat-
ed to 420 kPa (60 psi).
✽ ✽
NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
WARNING- Wheel studs
Do not drive your vehicle with
damaged wheel studs. If the
studs are damaged, they may
lose their ability to retain the
wheel. This could lead to the
loss of the wheel and a colli-
sion.WARNING
The compact spare tire is for
emergency use only. Do not
operate your vehicle on this
compact spare at speeds over 80
km/h (50 mph). The original tire
should be repaired or replaced
as soon as possible to avoid fail-
ure of the spare possibly leading
to personal injury or death.

It is possible that some tires, espe-
cially with larger punctures or dam-
age to the sidewall, cannot be sealed
completely.
Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle
is heavily loaded or if a trailer is in
use.
The Tire Mobility Kit is not designed
or intended as a permanent tire
repair method and is to be used for
one tire only.
This instruction shows you step by
step procedure to temporarily seal
the puncture.
Read the section "Notes on the safe
use of the Tire Mobility Kit".Notes on the safe use of the
Tire Mobility Kit
Park your car at the side of the
road so that you can work with the
Tire Mobility Kit away from moving
traffic.
To be sure your vehicle will not move, even when you're on fairly
level ground, always set your park-
ing brake.
Only use the Tire Mobility Kit for sealing/inflation passenger car
tires. Only punctured areas located
within the tread region of the tire
can be sealed using the tire mobil-
ity kit.
Do not use on motorcycles, bicy- cles or any other type of tires.
When the tire and wheel are dam- aged, do not use Tire Mobility Kit
for your safety.
Use of the Tire Mobility Kit may not be effective for tire damage larger
than approximately 6 mm (0.24 in).
Please contact the nearest Kia
dealership if the tire cannot be
made roadworthy with the Tire
Mobility Kit. Do not use the Tire Mobility Kit if a
tire is severely damaged by driving
run flat or with insufficient air pres-
sure.
Do not remove any foreign objects such as nails or screws that have
penetrated the tire.
Provided the car is outdoors, leave the engine running. Otherwise
operating the compressor may
eventually drain the car battery.
Never leave the Tire Mobility Kit unattended while it is being used.
Do not leave the compressor run- ning for more than 10 min. at a time
or it may overheat.
Do not use the Tire Mobility Kit if the ambient temperature is below -
-30°C (22°F).

What to do in an emergency
Distributing the sealant
11. Immediately drive approximately7~10km (4~6miles or, about
10min) to evenly distribute the
sealant in the tire.
Do not exceed a speed of 80 km/h
(50 mph). If possible, do not fall
below a speed of 20 km/h (12 mph).
While driving, if you experience any
unusual vibration, ride disturbance or
noise, reduce your speed and drive
with caution until you can safely pull
off of the side of the road.
Call for road side service or towing.
When you use the Tire Mobility Kit,
the tire pressure sensor valve stem
and wheel may be stained by
sealant. After use wipe off sealant
residue and inspect. Consult you Kia
dealership if necessary.
Checking the tire inflation
pressure
1.After driving approximately 7 ~ 10 km (4 ~ 6 miles or about 10 min),
stop at a safe location.
2.Connect connection hose (9) of the compressor directly to the tire
valve.
3.Plug the compressor power cord into the vehicle power outlet.
4.Adjust the tire inflation pressure to the recomended tire inflation.
With the ignition switch on, pro-
ceed as follows.
- To increase the inflation pres-sure : Switch on the compressor,
position I. To check the current
inflation pressure setting, briefly
switch off the compressor.
✽ ✽ NOTICE
The pressure gauge may show high-
er than actual reading when the
compressor is running. To get an
accurate tire reading, the compres-
sor needs to be turned off.
- To reduce the inflation pres-
sure: Press the button 8 on the
compressor.

Maintenance
TIRES 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 when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in chapter
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Inflate your tires consistent with
the instructions provided in this
manual. Severe underinflation (
70 kPa (10 psi) or more) can
lead to severe heat build-up,
causing blowouts, tread separa-
tion and other tire failures that
can result in the loss of vehicle
control. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
authorized Kia dealer.
Overinflation produces a harsh ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from road haz-
ards.
Warm tires normally exceed rec- ommended cold tire pressures by
28 to 41 kPa (4 to 6 psi). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
Be sure to reinstall the tire inflation valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If
a valve cap is missing, install a
new one as soon as possible. Always observe the following:
Check tire pressure when the tires
are cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1.6
km (one mile) since startup.)
Check the pressure of your spare tire each time you check the pres-
sure of other tires.
Never overload your vehicle. Be careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gauge to check
tire pressure. You can not tell if your
tires are properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they're underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1.6 km (1 mile).
