Jump starting procedure
✽
✽NOTICE
If the battery is discharged, the
engine can be started using a battery
of another vehicle and two jumper
cables. Only use jumper cables with
fully insulated clamp handles.
To prevent personal injury or dam-
age to both vehicles, adhere strictly
to the following procedure.
1.Make sure the booster battery is
12-volt and that its negative termi-
nal is grounded.
2.If the booster battery is in another vehicle, do not allow the vehicles to
touch.
3.Turn off all unnecessary electrical loads. 4.Connect the jumper cables in the
exact sequence shown in the illus-
tration. First connect one end of a
jumper cable to the positive termi-
nal of the discharged battery (1),
then connect the other end to the
positive terminal on the booster
battery (2). Proceed to connect
one end of the other jumper cable
to the negative terminal of the
booster battery (3), then the other
end to a solid, stationary, metallic
point (for example, the engine lift-
ing bracket) away from the battery
(4). Do not connect it to or near any
part that moves when the engine is
cranked.
Make sure that there is no contact
between the bodywork of the two
vehicles; otherwise, there is the
danger of short circuits.
Do not allow the jumper cables to
contact anything except the correct
battery terminals or the correct
ground. Do not lean over the bat-
tery when making connections. 5.Start the engine of the vehicle with
the booster battery and let it run at
2,000 rpm, then start the engine of
the vehicle with the discharged
battery. If the first starting attempt
is not successful, wait a few min-
utes before making another
attempt in order to allow the dis-
charged battery to recharge.
To charge the discharged battery
enough, it is recommended to let the
engine at idle or to drive the vehicle
for a certain period of time.
If the cause of your battery discharg- ing is not apparent, you should haveyour vehicle checked by an author-ized HYUNDAI dealer.
CAUTION - Battery cables
Do not connect the jumper cablefrom the negative terminal of thebooster battery to the negativeterminal of the discharged bat-tery. This can cause the dis-charged battery to overheat andcrack, releasing battery acid.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soonas it is safe to do so.
2. Place the shift lever in P and set the parking brake. If the air condi-
tioning is on, turn it off.
3. If engine coolant is running out under the car or steam is coming
out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off. 4. Check to see if the water pump
drive belt is missing. If it is not
missing, check to see that it is
tight. If the drive belt seems to be
satisfactory, check for coolant
leaking from the radiator, hoses or
under the car. (If the air condition-
ing had been in use, it is normal
for cold water to be draining from it
when you stop.)
5. If the water pump drive belt is bro- ken or engine coolant is leaking
out, stop the engine immediately
and call the nearest authorized
HYUNDAI dealer for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
CAUTION
Serious loss of coolant indi-cates there is a leak in the cool-ing system and this should bechecked as soon as possible byan authorized HYUNDAI dealer.
WARNING
Do not remove the radiator cap
when the engine is hot. This
may result in coolant being
blown out of the opening and
cause serious burns.

What to do in an emergency
✽
✽NOTICE
If any of the below happens, have
the system checked by an authorized
HYUNDAI dealer.
1.The low tire pressure telltale/
TPMS malfunction indicator does
not illuminate for 3 seconds when
Engine Start/Stop button is turned
to the ON or engine is running.
2. The TPMS malfunction indicator remains illuminated after blinking
for approximately 1 minute.
3. The Low tire pressure position telltale remains illuminated.
Low tire pressure
telltale
Low tire pressure position tell-
tale and tire pressure telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated and warning massage dis-
played on the cluster LCD display,
one or more of your tires is signifi-
cantly under-inflated. The low tire
pressure position telltale light will
indicate which tire is significantly
under-inflated by illuminating the cor-
responding position light. If either telltale illuminates, immedi-
ately reduce your speed, avoid hard
cornering and anticipate increased
stopping distances. You should stop
and check your tires as soon as pos-
sible. Inflate the tires to the proper
pressure as indicated on the vehi-
cle’s placard or tire inflation pressure
label located on the driver’s side cen-
ter pillar outer panel. If you cannot
reach a service station or if the tire
cannot hold the newly added air,
replace the low pressure tire with a
spare tire.
If you drive the vehicle for about 20
minutes at speeds above 15.5 mph
(25 km/h) after replacing the low
pressure tire with the spare tire, the
below will happen:
The TPMS malfunction indicator
may blink for approximately 1
minute and then remain continu-
ously illuminated because the
TPMS sensor is not mounted on
the spare wheel.

are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
Check coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.

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 car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing 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.

727
Maintenance
Vacuum crankcase ventilation
hoses (if equipped)
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 HYUNDAI air cleaner fil-
ter 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 HYUNDAI dealer
should perform the operation.
Cooling system
Check the cooling system parts,
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.

729
Maintenance
Parking brake
Inspect the parking brake system
including the parking brake lever (or
pedal) and cables.
Brake pads, calipers and
rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or dam-
age. Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant/
compressor (if equipped)
Check the air conditioning lines and
connections for leakage and dam-
age.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully. 5. Pull the dipstick out again and
check the level. The level should
be between F and L.
If it is near or at L, add enough oil to
bring the level to F.Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil. (Refer to "Recommended lubricantsand capacities" in section 8.)
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.
CAUTION
Do not overfill with engine oil.
Engine damage may result.
Do not spill engine oil, when adding or changing engine oil.If you spill engine oil on theengine room, wipe it off imme-diately.
