Jacking instructions
The jack is provided for emergency
tire changing only.
To prevent the jack from “rattling”
while the vehicle is in motion, store it
properly.
Follow jacking instructions to reduce
the possibility of personal injury. Always move the vehicle complete-
ly off the road and onto the shoul-
der before trying to change a tire.
The jack should be used on a firm
level ground. If you cannot find a
firm, level place off the road, call a
towing service company for assis-
tance.
Be sure to use the correct front and rear jacking positions on the vehi-
cle; never use the bumpers or any
other part of the vehicle for jack
support.
Do not allow anyone to remain in the vehicle while it is on the jack.
Make sure any children present are in a secure place away from
the road and from the vehicle to be
raised with the jack.
WARNING- Changing
tires
Never attempt vehicle repairs in
the traffic lanes of a public road
or highway.
OJF065003
WARNING- Tire Jack
Do not place any portion of your
body under a vehicle that is
only supported by a jack since
the vehicle can easily roll off the
jack. Use vehicle support
stands.
WARNING- Running vehi- cle on jack
Do not start or run the engine of
the vehicle while the vehicle is
on the jack as this may cause
the vehicle to fall off the jack.

What to do in an emergency
Position the wrench as shown in the
drawing and tighten the wheel nuts.
Be sure the socket is seated com-
pletely over the nut. Do not stand on
the wrench handle or use an exten-
sion pipe over the wrench handle. Go
around the wheel, tightening every
nut following the numerical sequence
shown in the image until they are all
tight. Double-check each nut for
tightness. After changing wheels,
have an authorized Kia dealer tight-
en the wheel nuts to their proper
torque as soon as possible.
Wheel nut tightening torque:
79~94 lbf·ft (11~13 kgf·m)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, dust and dirt may get
into the tire valve and air may leak
from the tire. If you lose a valve cap,
buy another and install it as soon as
possible.
After you have changed the 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.

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.
Pay particular attention to the hose
surfaces nearest to high heat
sources, such as the exhaust mani-
fold.
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 for excessive valve noise
and/or engine vibration and adjust if
necessary. An authorized Kia dealer
should perform this procedure.
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.
Automatic transmission fluid
Automatic transmission 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.
✽ ✽NOTICE
Automatic transmission fluid color
is usually red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker.
This is normal, and you should not
judge the need to replace the fluid
based upon the changed color.

Maintenance
Checking the parking brake
Check whether the stroke is within
specification when the parking brake
pedal is pressed with 66 lb, 294 N
(30 kg) of force. 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 : 6~7 notch
