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
section 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see sec-
tion 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.

 Remember, your vehicle does not
require extended warm-up. After
the engine has started, allow the
engine to run for 10 to 20 seconds
prior to placing the vehicle in gear.
In very cold weather, however, give
your engine a slightly longer warm-
up period.
 Don't “lug” or “over-rev” the engine. Lugging is driving too slowly in a
very high gear resulting in engine
bucking. If this happens, shift to a
lower gear. Over-revving is racing
the engine beyond its safe limit.
This can be avoided by shifting at
the recommended speed.  Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
 Open windows at high speeds can reduce fuel economy.
 Fuel economy is reduced by cross- winds and headwinds. To help off-
set some of this loss, slow down
when driving in these conditions.
Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized Kia dealer perform
scheduled inspections and mainte-
nance.
WARNING- Engine off during
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 running. In addition,
turning off the ignition while
driving could engage the steer-
ing wheel lock resulting in loss
of vehicle steering. Keep the
engine on and downshift to an
appropriate gear for engine
braking effect.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
 Drive cautiously and allow extradistance for braking.
 Avoid sudden braking or steering.
 When braking with non-ABS brakes, pump the brake pedal with
a light up-and-down motion until
the vehicle is stopped. Do not pump the brake pedal on a
vehicle equipped with ABS.
 If stalled in snow, mud, or sand,
use second gear. Accelerate slow-
ly to avoid spinning the drive
wheels.
 Use sand, rock salt, tire chains, or other non-slip material under the
drive wheels to provide traction
when stalled in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and any
forward gear in vehicles equipped
with an Intelligent Variable
Transmission. Do not race the
engine, and spin the wheels as little
as possible. If you are still stuck after
a few tries, have the vehicle pulled
out by a tow vehicle to avoid engine
overheating and possible damage to
the transmission.
The ESC system should be turned
OFF prior to rocking the vehicle.
SPECIAL DRIVING CONDITIONS
CAUTION- Vehicle
rocking
Prolonged rocking may causeengine overheating, transmis-sion damage or failure, and tiredamage.
WARNING- Downshifting
Do not downshift with an intelli-
gent variable transmission
while driving on slippery sur-
faces. The sudden change in
tire speed could cause the tires
to skid and result in an acci-
dent.

Driving your vehicle
 Adjust your mirrors to reduce theglare from other driver's head-
lights.
 Keep your headlights clean and properly aimed on vehicles not
equipped with the automatic head-
light aiming feature. Dirty or
improperly aimed headlights will
make it much more difficult to see
at night.
 Avoid staring directly at the head- lights of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.Driving in the rain
Rain and wet roads can make driving
dangerous, especially if you’re not
prepared for the slick pavement.
Here are a few things to consider
when driving in the rain:
 A heavy rainfall will make it harderto see and will increase the dis-
tance needed to stop your vehicle,
so slow down.
 Keep your windshield wiping equipment in good shape. Replace
your windshield wiper blades when
they show signs of streaking or
missing areas on the windshield.  If your tires are not in good condi-
tion, making a quick stop on wet
pavement can cause a skid and
possibly lead to an accident. Be
sure your tires are in good shape.
 Turn on your headlights to make it easier for others to see you.
 Driving too fast through large pud- dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
 If you believe you may have gotten your brakes wet, apply them lightly
while driving until normal braking
operation returns.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
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.
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
section 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.

Severe weather conditions in the
winter result in greater wear and
other problems. To minimize the
problems of winter driving, you
should follow these suggestions:
Snowy or Icy conditions
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
If snow tires are needed, it is neces-
sary to select tires equivalent in size
and type of the original equipment
tires. Failure to do so may adversely
affect the safety and handling of your
car. Furthermore, speeding, rapid
acceleration, sudden brake applica-
tions, and sharp turns are potentially
very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids. You need to
keep sufficient distance between the
vehicle in operation in front and your
vehicle. Also, apply the brake gently.
It should be noted that installing tire
chains on the tire will provide greater
driving force, but will not prevent side
skids.
Tire chains are not legal in all states.
Check state laws before installing tire
chains.
Snow tires
If you mount snow tires on your vehi-
cle, make sure they are radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
Keep in mind that the traction provid-
ed by snow tires on dry roads may
not be as high as your vehicle's orig-
inal equipment tires. You should drive
cautiously even when the roads are
clear. Check with the tire dealer for
maximum speed recommendations.
Do not install studded tires without
first checking local, state and munic-ipal regulations for possible restric-tions against their use.
WINTER DRIVING
OYB051170L
WARNING- Snow tire size
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your vehi-
cle may be adversely affected.

Chain installation
When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear the chains contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
chains as soon as you begin driving
on cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place a
triangular emergency warning device
behind the vehicle if available.
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing snow
chains.  The use of chains may adversely
affect vehicle handling.
 Do not exceed 20 mph (30 km/h) or the chain manufacturer’s recom-
mended speed limit, whichever is
lower.
 Drive carefully and avoid bumps, holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
 Avoid sharp turns or locked-wheel braking.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 section 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 section 7. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
CAUTION- Snow chains
 Chains that are the wrong size or improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
 Stop driving and retighten the chains any time you hear themhitting the vehicle.

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
section 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 section 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 finish.
Don't let your parking brake
freeze
Under some conditions, your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen when there is an accumulation
of snow or ice around or near the
rear brakes or if the brakes are wet.
If there is a risk the parking brake
may freeze, apply it only temporarily
while you put the shift lever in P
(Intelligent Variable Transmission)
and chock the rear wheels so the
vehicle cannot roll. Then release the
parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com-
ponents is not obstructed.

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 con-
trol. 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 traf-
fic lanes.
2. When the vehicle is stopped, turn on your emergency hazard flash-
ers, set the parking brake and put
the transmission in P (Intelligent
Variable Transmission). 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 section.
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.
