R (Reverse)
Use this position to drive the vehicle
backward.
N (Neutral)
The wheels and transaxle are not
engaged. The vehicle will roll freely
even on the slightest incline unless
the parking brake or service brakes
are applied. D (Drive)
This is the normal forward driving
position. The transaxle will automati-
cally shift through a 6-gear
sequence, providing the best fuel
economy and power.
For extra power when passing anoth-
er vehicle or climbing grades,
depress the accelerator fully, at
which time the transaxle will auto-
matically downshift to the next lower
gear.
Sports mode
Whether the vehicle is stopped or in
motion, sports mode is selected by
pushing the shift lever from the D
(Drive) position into the manual gate.
To return to D (Drive) range opera-
tion, push the shift lever back into the
main gate.
In sports mode, moving the shift
lever backwards and forwards will
allow you to make gearshifts rapidly.
In contrast to a manual transaxle, the
sports mode allows gearshifts with
the accelerator pedal depressed.
CAUTION - Shifting
Always come to a complete stop
before shifting into or out of R(Reverse); you may damage thetransaxle if you shift into R(Reverse) while the vehicle is inmotion, except when “Rockingthe Vehicle” explained in thischapter.

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.
ECONOMICAL OPERATION

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.

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.

Driving your vehicle
This chapter will guide you in the
proper loading of your vehicle and/or
trailer, to keep your loaded vehicle
weight within its design rating capa-
bility, with or without a trailer.
Properly loading your vehicle will
provide maximum return of the vehi-
cle design performance. Before load-
ing your vehicle, familiarize yourself
with the following terms for determin-
ing your vehicle's weight ratings, with
or without a trailer, from the vehicle's
specifications and the compliance
label:
Base curb weight
This is the weight of the vehicle
including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or option-
al equipment.
Vehicle curb weight
This is the weight of your new vehicle
when you picked it up from your deal-
er plus any aftermarket equipment.Cargo weight
This figure includes all weight added
to the Base Curb Weight, including
cargo and optional equipment.
GAW (Gross axle weight)
This is the total weight placed on
each axle (front and rear) - including
vehicle curb weight and all payload.
GAWR (Gross axle weight rating)
This is the maximum allowable
weight that can be carried by a single
axle (front or rear). These numbers
are shown on the compliance label.
The total load on each axle must
never exceed its GAWR.
GVW (Gross vehicle weight)
This is the Base Curb Weight plus
actual Cargo Weight plus passen-
gers.
GVWR (Gross vehicle weight rating)
This is the maximum allowable
weight of the fully loaded vehicle
(including all options, equipment,
passengers and cargo). The GVWR
is shown on the certification label
located on the driver’s door sill.

What to do in an emergency
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
If you have a flat tire while
driving
If a tire goes flat while you are driv-
ing:
1.Take your foot off the acceleratorpedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately or attempt to pull off the road
as this may cause a loss of control.
When the vehicle has slowed down
to such a speed that it is safe to do
so, brake carefully and pull off the
road. Drive off the road as far as
possible and park on a firm level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes. 2.When the vehicle is stopped, turn
on your emergency hazard flash-
ers, set the parking brake and put
the transaxle in P (automatic
transaxle).
3.Have all passengers get out of the vehicle. Be sure they all get out on
the side of the vehicle that is away
from traffic.
4.When changing a flat tire, follow the instruction provided later in this
chapter.
If engine stalls while driving
1.Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2.Turn on your emergency flashers.
3.Try to start the engine again. If your vehicle will not start, contact an
authorized Kia dealer or seek other
qualified assistance.
IN CASE OF AN EMERGENCY WHILE DRIVING

What to do in an emergency
Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the bat-
tery when making connections.
5.Start the engine of the vehicle with the booster battery and let it run at
2,000 rpm, then start the engine of
the vehicle with the discharged
battery.
If the cause of your battery discharg-ing is not apparent, you should haveyour vehicle checked by an author-ized Kia dealer.
Push-starting
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this chapter
for jump-starting.
WARNING - Tow starting
vehicle
Never tow a vehicle to start it
because the sudden surge for-
ward when the engine starts
could cause a collision with the
tow vehicle.
WARNING - Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative
terminal of the discharged bat-
tery. This can cause the dis-
charged battery to overheat and
crack, releasing battery acid.

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.

Using the Tire Mobility Kit
1.Detach the speed restriction label
(0) from the sealant bottle (1), and
place it in a highly visible place
inside the vehicle such as on the
steering wheel to remind the driver
not to drive too fast.
2.Screw connection hose (9) onto the connector of the sealant bottle.
3.Ensure that button (8) on the com- pressor is not pressed.
4.Unscrew the valve cap from the valve of the defective wheel and
screw filling hose (2) of the sealant
bottle onto the valve.
5.Insert the sealant bottle into the housing of the compressor (4)so
that the bottle is upright.
✽ ✽ NOTICE
If a foreign object is seen that has
punctured the tire, do not remove it
before using Tire Mobility Kit.
6.Ensure that the compressor is
switched off, position 0.
7 Connect between compressor and the vehicle power outlet using the
cable and connectors.
8.With the engine start/stop button position on or ignition switch posi-
tion on, switch on the compressor
and let it run for approximately 5~7
minutes to fill the sealant up to
proper pressure. (refer to the Tire
and Wheels, chapter 8). The infla-
tion pressure of the tire after filling
is unimportant and will be
checked/corrected later.
Be careful not to overinflate the tire
and stay away from the tire when
filling it. 9.Switch off the compressor.
10. Detach the hoses from the
sealant bottle connector and
from the tire valve.
Return the Tire Mobility Kit to its stor-
age location in the vehicle.
WARNING
Carbon monoxide poisoning
and suffocation is possible if
the engine is left running in a
poorly ventilated or unventilat-
ed location (such as inside a
building).
WARNING - Tire pressure
Do not attempt to drive your
vehicle if the tire pressure is
below 200kPa (29 psi). This
could result in an accident due
to sudden tire failure.

Maintenance
Automatic transaxle fluid
Automatic transaxle fluid should not
be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
Kia dealer in accordance to the
scheduled maintenance at the begin-
ning of this chapter.
✽ ✽NOTICE
Automatic transaxle fluid color is
basically red.
As the vehicle is driven, the auto-
matic transaxle fluid will begin to
look darker.
It is normal condition and you
should not judge the need to replace
the fluid based upon the changed
color.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
