IF THE ENGINE WILL NOT START
If engine doesn't turn over or
turns over slowly
1. If your vehicle has an automatictransaxle, 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.

3. Install the towing hook by turning it
clockwise into the hole until it is
fully secured.
4. Remove the towing hook and install the cover after use.Emergency towing
If towing is necessary, have it
done by an authorized Kia dealer
or a commercial tow truck service. If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook under the front (or rear) of
the vehicle. Use extreme caution
when towing the vehicle. A driver
must be in the vehicle to steer it and
operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speed.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Do not use the tow hooks to pull a
vehicle out of mud, sand or other
conditions from which the vehicle
cannot be driven out under its own
power.
Avoid towing a vehicle heavier than the vehicle doing the towing.
The drivers of both vehicles should communicate with each other fre-
quently.

What to do in an emergency
Attach a towing strap to the towhook.
Use only a cable or chain specifical- ly intended for use in towing vehi-
cles. Securely fasten the cable or
chain to the towing hook provided.
Before emergency towing, check if the hook is not broken or damaged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply it steadily and with even force.
To avoid damaging the hook, do not pull from the side or at a vertical
angle. Always pull straight ahead. Use a towing strap less than 16
feet (5 m) long. Attach a white or
red cloth (about 12 inches (30 cm)
wide) in the middle of the strap for
easy visibility.
Drive carefully so that the towing strap is not loosened during tow-
ing.
CAUTION
Using a portion of the vehicleother than the tow hooks fortowing may damage the body ofyour vehicle.
WARNING- Emergency
Towing Precautions
Use extreme caution when tow-
ing the vehicle.
Avoid sudden starts or erratic driving maneuvers which
would place excessive stress
on the emergency towing hook
and towing cable or chain. The
hook and towing cable or
chain may break and cause
serious injury or damage.
If the disabled vehicle is unable to be moved, do not
forcibly continue the towing.
We recommend that you con-
tact an authorized Kia dealer
or a commercial tow truck
service for assistance.
Tow the vehicle as straight ahead as possible.
Keep away from the vehicle during towing.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
HSG (Hybrid starter & genera-
tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel filter (for gasoline)
Kia gasoline vehicles are equipped a
lifetime fuel filter that is integrated
with the fuel tank. Regular mainte-
nance or replacement is generally
not needed but depends on fuel
quality. If there are some important
fuel related problems like fuel flow
restriction, surging, loss of power,
hard starting problem etc, fuel filter
inspection or replace is needed.
The fuel filter be Inspected or
replaced by an authorized Kia dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized Kia dealer
replace any damaged or leaking
parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.
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.
