Be sure the exhaust system does
not leak.
The exhaust system should be
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.
WARNING- Open trunk
Do not drive with the trunk open.
Poisonous exhaust gases can
enter the passenger compart-
ment. If you must drive with the
trunk open proceed as follows:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at “Fresh”, the air flow control
at “Floor” or “Face” and the
fan at the highest speed.

DRIVER’S ATTENTION
The driver must be cautious in the
below situations may not work
properly when recognition of the
lane marker is poor or limited :  When lane and road condition is
poor
• It is difficult to distinguish the lane marker from road when the lane
marker is covered with dust or
sand.
• It is difficult to distinguish the color of the lane marker from
road.
• There is something looks like a lane marker.
• The lane marker is indistinct or damaged.
• The number of lanes increases/ decreases or the lane lines are
crossing (Driving through a toll
plaza/toll gate, merged/divided
lane).
• There are more than two lane markers.
• The lane marker is very thick or thin. (Continued)(Continued)
• The lane marker is not visible due
to snow, rain, stain, a puddle or
other factors.
• A shadow is on the lane marker because of a median strip,
guardrail, noise barriers and oth-
ers.
• When the lane markers are com- plicated or a structure substitutes
for the lines such as a construc-
tion area.
• There are crosswalk signs or other symbols on the road.
• The lane suddenly disappears such as at the intersection.
• The lane marker in a tunnel is cov- ered with dirt or oil and etc.
  When external condition is inter-
vened
• The brightness of outside changes suddenly when entering/existing a
tunnel or passing under a bridge.
• The headlamps are not on at night or in a tunnel, or light level is low.
• There is a boundary structure in the roadway. (Continued)(Continued)
• The light of street, sun, oncoming
vehicle and so on reflects from the
water on the road.
• When light shines brightly in the reverse direction you drive.
• The distance from the vehicle ahead is very short or the vehicle
ahead drives hiding the lane line.
• You drive on a steep grade or a sharp curve.
• The vehicle vibrates heavily.
• The temperature near inside mir- ror is very high due to direct sun
light and etc.
  When front visibility is poor
• The lens or windshield is covered by strange materials.
• The sensor cannot detect the lane because of fog, heavy rain or snow.
• The windshield is fogged by humid air in the vehicle.
• Putting something on the crash pad and etc.

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.

What to do in an emergency
46
IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransmission / dual clutch trans-
mission, be sure the shift lever is
in N (Neutral) or P (Park) and the
emergency brake is set.
2. Check the battery connections to be sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you oper-
ate the starter, the battery is dis-
charged.
4. Check the starter connections to be sure they are securely tight-
ened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1. Check the fuel level.
2. With the ignition switch in theLOCK position, check all connec-
tors at the ignition coils and spark
plugs. Reconnect any that may be
disconnected or loose.
3. Check the fuel line in the engine compartment.
4. If the engine still does not start, call an authorized Kia dealer or
seek other qualified assistance.
WARNING - Push/
pull start
Do not push or pull the vehicle
to start it. Push or pull starting
may cause the catalytic con-
verter to overload and create a
fire hazard.
