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 gal-
lon (liter) 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:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to the traffic so you don't have to
change speeds unnecessarily. Avoid
heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary 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 con-
sumption. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption.
Keep your vehicle in good condition. For better fuel economy and reduced
maintenance costs, maintain your vehi-
cle in accordance with the mainte-
nance schedule in section 7. If you
drive your vehicle in severe conditions,
more frequent maintenance is required
(see section 7 for details). Keep your vehicle clean. For maximum
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 unnecessary 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 plac-
ing 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 avoid-
ed by shifting at the recommended
speed.
ECONOMICAL OPERATION

Driving your vehicle
32
5
Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
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
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 run-
ning. In addition, turning off the
ignition while driving could engage
the steering 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 hazards, follow
these suggestions:
Drive cautiously and allow extra dis-tance 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 vehi-
cle equipped with ABS.
If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, or other non-slip material under the drive wheels to pro-
vide 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 1st (First)
and R (Reverse) in vehicles equipped
with a manual transaxle or R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle. 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 over-
heating and possible damage to the
transaxle.
The ESC system should be turned OFF
prior to rocking the vehicle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Do not downshift with an automatic
transaxle while driving on slippery
surfaces. The sudden change in tire
speed could cause the tires to skid
and result in an accident.
CAUTION - Vehicle
rocking
Prolonged rocking may causeengine overheating, transaxle dam-age or failure, and tire damage.

Smooth cornering
Avoid braking or gear changing in cor-
ners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration. If you follow
these suggestions, tire wear will be held
to a minimum.
Driving at night
Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
Adjust your mirrors to reduce the glare from other driver's headlights.
OBH058035LOMC035004
WARNING - Sudden
vehicle movement
Do not attempt to rock the vehicle if
people or objects are nearby. The
vehicle may suddenly move for-
ward or backwards as it becomes
unstuck.
CAUTION - Spinning tires
Do not spin the wheels, especially
at speeds more than 56 km/h (35mph). Spinning the wheels at highspeeds when the vehicle is station-ary could cause a tire to overheat which could result in tire damage.

535
Driving your vehicle
Keep your headlights clean and prop-erly aimed on vehicles not equipped
with the automatic headlight aiming
feature. Dirty or improperly aimed
headlights will make it much more diffi-
cult to see at night.
Avoid staring directly at the headlights of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous, especially if you’re not pre-
pared for the slick pavement. Here are a
few things to consider when driving in the
rain:
A heavy rainfall will make it harder tosee and will increase the distance
needed to stop your vehicle, so slow
down.
Keep your windshield wiping equip- ment 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 condition,
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 eas- ier for others to see you.
Driving too fast through large puddles 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 oper-
ation returns.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er 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 several
times while the vehicle is moving slowly.

Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
Never exceed the maximum tire inflation
pressure shown on the tires.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks of
roots of trees. Become familiar with the
off-road conditions where you are going
to drive before you begin driving.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both the engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
WARNING - Under/over
inflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated tires
can cause poor handling, loss of
vehicle control, and sudden tire fail-
ure leading to accidents, injuries,
and even death. For proper tire
pressures, refer to “Tires and
wheels” in section 8.
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.

537
Driving your vehicle
Severe weather conditions in the winter
result in greater wear and other prob-
lems. To minimize the problems of winter
driving, you should follow these sugges-
tions:
Snowy or Icy conditions
To drive your vehicle in deep snow, it may
be necessary to use snow tires on your
tires. If snow tires are needed, it is nec-
essary 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 accelera-
tion, sudden brake applications, and
sharp turns are potentially very haz-
ardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake appli-
cations on snowy or icy roads may cause
skids. You need to keep sufficient dis-
tance between the vehicle in operation in
front and your vehicle. Also, apply the
brake gently.
Snow tires
If you mount snow tires on your vehicle,
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 provided by snow tires on dry
roads may not be as high as your vehi-
cle's original equipment tires. You should
drive cautiously even when the roads are
clear. Check with the tire dealer for max-
imum speed recommendations.
Do not install studded tires without firstchecking local, state and municipal regu- lations for possible restrictions againsttheir use.
WINTER DRIVING
1JBB3305

Driving your vehicle

Use high quality ethylene glycol
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 cooling system, lubri-
cates 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 bat-
tery and cables as described in section
7. Never attempt to check the Hybrid
High Voltage Battery. The level of charge
in your battery can be checked by an
authorized Kia dealer or a service sta-
tion.
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 ignition
system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents 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
heated 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 instructions on the con-
tainer. Window washer 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.

539
Driving your vehicle
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 temporar-
ily while you put the shift lever in P (auto-
matic transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.
Don't let ice and snow accumu-
late underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.
Carry emergency equipment
Depending on the severity of the weath-
er you should carry appropriate emer-
gency equipment. Some of the items you
may want to carry include, tow straps or
chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a window
scraper, gloves, ground cloth, coveralls, a
blanket, etc.
