Make sure any children present are
in a secure place away from the road
and from the vehicle to be raised with
the jack.Removing and storing the

counterclockwise.
Store the tire in the reverse order of
removal.
To prevent the spare tire and tools
from “rattling” while the vehicle is in
motion, store them properly.

1.Park on a level surface and apply
the parking brake firmly.
2.Shift the shift lever into P (Park) for automatic transaxle.

What to do in an emergency
Then position the wrench as shown
in the drawing and tighten the wheel
nuts. Be sure the socket is seated
completely over the nut. Do not stand
on the wrench handle or use an
extension pipe over the wrench han-
dle.
Go around the wheel tightening
every nut following the numerical
sequence shown in the image until
they are tight. Then double-check
each nut for tightness. After changing
the wheels, have an authorized Kia
dealer tighten the wheel nuts to their
proper torque as soon as possible.Wheel nut tightening torque:
Steel wheel & aluminium alloy wheel:
9~11 kg.m (65~79 lb.ft)
If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting the tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy
another and install it as soon as pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.
Note that most lug nuts do not have
metric threads. Be sure to use
extreme care in checking for thread
style before installing aftermarket lug
nuts or wheels. If in doubt, consult an
authorized Kia dealer.

CAUTION - Reusing lug
nuts
Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Your vehicle has metric threadson the wheel studs and nuts.Installation of a non-metricthread nut on a metric stud willnot secure the wheel to the hubproperly and will damage thestud so that it must be replaced.

Removable towing hook
(if equipped)
1.Open the trunk, and remove the
towing hook from the tool case.
2.Remove the hole cover pressing the lower part of the cover on the
bumper.
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 rear of the vehi-
cle. Use extreme caution when tow-
ing 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 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
Before emergency towing, checkthat the hook is not broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force.
To avoid damaging the hook, do not pull from the side or at a verti-
cal angle. Always pull straight
ahead. Use a towing strap less than 5 m
(16 feet) long. Attach a white or red
cloth (about 30 cm (12 inches)
wide) in the middle of the strap for
easy visibility.
Drive carefully so that the towing strap is not loosened during tow-
ing.
CAUTION
Attach a towing strap to the tow hook.
Using a portion of the vehicle other than the tow hooks fortowing may damage the bodyof your vehicle.
Use only a cable or chain specifically intended for usein towing vehicles. Securelyfasten the cable or chain tothe towing hook provided.
WARNING
Use extreme caution when tow-
ing the vehicle.
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 dam-
age.
If the disabled vehicle is unable to be moved, do not
forcibly continue the towing.
Contact 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.

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.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized Kia dealer
should perform the operation.
Cooling system
Check cooling system components,
such as 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.

PARKING BRAKE
Checking the parking brake
Ty p e A
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 20 kg (44 lb,
196 N) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade.
Type B
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 : 6~8 “clicks’’ at a force of
20kg (44 lbs, 196 N).OTF050015

BATTERY
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.
WARNING - Risk of
explosion
Keep lit cigarettes and
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.WARNING - Sulfuric acid
in batteries
Keep batteries out of the reach of children
because batteries con-
tain highly corrosive
SULFURIC ACID and
electrolytes. Do not
allow battery acid to
contact your skin, eyes,
clothing or paint finish.
Wear eye protection when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.
