Features of your vehicle
Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system. If
dust or other pollutants accumulate in
the filter over a period of time, the air
flow from the air vents may decrease,
resulting in moisture accumulation on
the inside of the windshield even
when the outside (fresh) air position is
selected. If this happens, have the cli-
mate control air filter replaced by an
authorized Kia dealer.
✽ ✽NOTICE
• Replace the filter every 15,000
miles or once a year.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent air
conditioner filter inspections and
changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized Kia
dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a negative impact on the air con-
ditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.

ant is mildly inflam-
mable and at very
high pressure, the air
conditioning system
should only be serv-
iced by trained and
certified technicians.
It is important that the correct
type and amount of oil and
refrigerant is used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.

checked whenever the vehicle is
raised to change the oil or for any
other purpose. If you hear a change in
the sound of the exhaust or if you drive
over something that strikes the under-
neath side of the vehicle, have the
exhaust system checked as soon as
possible by an authorized Kia dealer.
WARNING- Engineexhaust
Do not inhale exhaust fumes or
leave your engine running in a
enclosed area for a prolonged
time. Exhaust fumes contain
carbon monoxide, a colorless,
odorless gas that can cause
unconsciousness and death by
asphyxiation.

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.
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- 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 sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
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.

Driving your vehicle
The use of chains may adverselyaffect 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 8. 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 8. 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 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 8 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.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.
