What to do in an emergency
Emergency towingIf towing is necessary, we recom-
mend you have it done by an
authorized Kia dealer or a com-
mercial 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 speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Do not use the towing hooks to pulla 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.
Attach a towing strap to the towing hook.
Using a portion of the vehicle other than the tow hooks for towing may
damage the body of your vehicle.
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.
Accelerate or decelerate the vehicle in a slow and gradual manner while
maintaining tension on the tow rope
or chain to start or drive the vehicle,
otherwise tow hooks and the vehi-
cle may be damaged.
Before emergency towing, check that the hook is broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply it steadily with even force.
To avoid damaging the hook, do not pull from the side or at a vertical
angle. Always pull straight ahead.

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 rec-
ommended when the filter is replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance (if equipped)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized Kia dealer
should perform the operation.
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
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
Intelligent Variable
Transmission (IVT) fluid
(if equipped)
The Intelligent Variable Transmission
(IVT) fluid should not be checked
under normal usage conditions.
But in severe conditions, the fluid
should be changed at an authorized
Kia dealer in accordance to the
scheduled maintenance at the begin-
ning of this chapter.
(Refer to “Maintenance Under Severe
Usage Conditions” this chapter.)

Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, have the parking
brake adjusted by an authorized Kia
dealer.
Stroke : 5~7 “clicks’’ at a force of 44
lbs (20 kg, 196 N).

For best battery service
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a
solution of water and baking soda.
If the vehicle is not going to be used for an extended time, discon-
nect the battery cables. Always read the following
instructions carefully when
handling a battery.
If any electrolyte gets into your eyes, flush your eyes
with clean water for at least
15 minutes and get immedi-
ate medical attention.
If electrolyte gets on your
skin, thoroughly wash the
contacted area. If you feel
pain or a burning sensation,

all other flames or
sparks away from the
battery.
The battery contains hydrogen -- a highly
combustible gas which
will explode if it comes
in contact with a flame or
spark.
Keep batteries out of the reach of children
because batteries con-
tain highly corrosive
SULFURIC ACID and
electrolytes. Do not
allow battery acid to

CAUTION
Do not input any other objects except fuses or relays intofuse/relay terminals such as adriver or wiring. It may causecontact failure and systemmalfunction.
Do not plug in screwdrivers or aftermarket wiring into the ter-minal originally designed forfuse and relays only. The elec-trical system and wiring of thevehicle interior may be dam-aged or burned due to contactfailure.
If you directly connect the wire on the taillight or replacethe bulb which is over the reg-ulated capacity to install trail-ers etc., the inner junctionblock can get burned.
