Driving your vehicle

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 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
47
IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. 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.

Maintenance
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections for
leakage and damage. Replace any
damaged parts.
Coolant (Engine / Inverter)
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
