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 your vehicle
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
result in overheating of 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 8.

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
vehicle. Furthermore, speeding,
rapid acceleration, sudden brake
applications, 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 to occur. You
need to keep sufficient distance
between the vehicle in operation in
front of your vehicle. Also, apply the
brake gently. It should be noted that
installing tire chains on the tire will
provide a greater driving force, but
will not prevent side skids.
Tire chains are not legal in all states.
Check state laws before fitting 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 withoutfirst checking local, state and munic-ipal regulations for possible restric-tions against their use.
WINTER DRIVING
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.

Driving your vehicle
1585
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 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.
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.

5 159
Driving your 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
chapter 9 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and ignition
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.
Don’t let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
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 gear shift lever in P
(Park, Automatic Transmission) and
block 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
vehicle to be sure the movement of
the front wheels and the steering
components are not obstructed.

5 161
Driving your vehicle
If you are considering towing with
your vehicle, you should first check
with your state's Department of
Motor Vehicles to determine the legal
requirements.
Since laws vary the requirements for
towing trailers, cars, or other types of
vehicles or apparatus may differ. Ask
an authorized Kia dealer for further
details before towing.
You may require an additional wiring
harness connector to install a trailer
hitch. Please contact an authorized
Kia dealer for more details.Your vehicle can tow a trailer. To
identify what the vehicle trailering
capacity is for your vehicle, you
should read the information in
“Weight of the trailer” that appears
later in this section.Remember that trailering is different
than just driving your vehicle by itself.
Trailering means changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires
correct equipment, and it has to be
used properly.
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.
Load-pulling components such as
the engine, transmission, 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 addi-
tional burden generates extra heat.
The trailer also adds considerably to
wind resistance, increasing the
pulling requirements.
TRAILER TOWING
CAUTION - Trailer

Follow instructions in this sec-tion when pulling a trailer.Pulling a trailer improperly candamage your vehicle and resultin costly repairs not covered byyour warranty.
WARNING- Towing a
trailer
Always check your towing
equipment to confirm correct
equipment size and installation
before use. Using incompatible
or incorrectly installed trailer
equipment can affect the vehi-
cle operation and endanger you
and your passengers.
WARNING- Weight
limits
Before towing, make sure the
total trailer weight, GCW (gross
combination weight), GVW
(gross vehicle weight), GAW
(gross axle weight) and trailer
tongue load are all within the
limits.

5 163
Driving your vehicle
Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get
to know your trailer. Acquaint your-
self with the feel of handling and
braking with the added weight of the
trailer. And always keep in mind that
the vehicle you are driving is now a
good deal longer and not nearly so
responsive as your vehicle is by
itself.
Before you start, check the trailer
hitch and platform, safety chains,
electrical connector(s), lights, tires
and mirror adjustment. If the trailer
has electric brakes, start your vehicle
and trailer moving and then apply the
trailer brake controller by hand to be
sure the brakes are working. This lets
you check your electrical connection
at the same time.
During your trip, check occasionally
to be sure that the load is secure,
and that the lights and any trailer
brakes are still working.
Following distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without a trailer.
This can help you avoid situations
that require heavy braking and sud-
den turns.
Passing
You’ll need more passing distance
up ahead when you’re towing a trail-
er. And, because of the increased
vehicle length, you’ll need to go
much farther beyond the passed
vehicle before you can return to your
lane. Due to the added load to the
engine when going uphill the vehicle
may also take longer to pass than it
would on flat ground.
Backing up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, just move your
hand to the left. To move the trailer to
the right, move your hand to the
right. Always back up slowly and, if
possible, have someone guide you.
Making turns
When you’re turning with a trailer,
make wider turns than normal. Do
this so your trailer won’t strike soft
shoulders, curbs, road signs, trees,
or other objects near the edge of the
road. Avoid jerky or sudden maneu-
vers. Signal well in advance before
turning or lane changes.

Driving your vehicle
1645
Turn signals when towing a trailer
When you tow a trailer, your vehicle
has to have a different turn signal
flasher and extra wiring. The green
arrows on your instrument panel will
flash whenever you signal a turn or
lane change. Properly connected,
the trailer lights will also flash to alert
other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green
arrows on your instrument panel will
flash for turns even if the bulbs on
the trailer are burned out. Thus, you
may think drivers behind you are
seeing your signals when, in fact,
they are not. It’s important to check
occasionally to be sure the trailer
bulbs are still working. You must also
check the lights every time you dis-
connect and then reconnect the
wires.
Do not connect a trailer lighting sys-
tem directly to your vehicle’s lighting
system. Use only an approved trailer
wiring harness.
An authorized Kia dealer can assist
you in installing the wiring harness.
Driving on grades
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don’t shift
down, you might have to use your
brakes so much that they would get
hot and no longer operate efficiently.
On a long uphill grade, shift down
and reduce your speed to around 45
mph (70 km/h) to reduce the possibil-
ity of engine and transmission over-
heating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transmission, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat build up and extend the life of
your transmission.CAUTION
Always use an approved trailerwiring harness. Failure to usean approved trailer wiring har-ness could result in damage tothe vehicle electrical system.
