EMERGENCY STARTING
Connect cables in numerical order and
disconnect in reverse order.
✽✽ NOTICE
Your vehicle has a battery in the trunk
room, but when you jump start your
vehicle, use the jumper terminal in the
engine room.
Jump starting
Jump starting can be dangerous if done
incorrectly. Therefore, to avoid harm to
yourself or damage to your vehicle or
battery, follow the jump starting proce-
dures. If in doubt, we strongly recom-
mend that you have a competent techni-
cian or towing service jump start your
vehicle.
CAUTION
Use only a 12-volt jumper system. You can damage a 12-volt startingmotor, ignition system, and otherelectrical parts beyond repair byuse of a 24-volt power supply (either
two 12-volt batteries in series or a 24-volt motor generator set).
WARNING - Battery
• Keep all flames or sparks away from the battery. The battery pro-
duces hydrogen gas which may
explode if exposed to flame orsparks.
If these instructions are not fol-
lowed exactly, serious personal
injury and damage to the vehicle
may occur! If you are not sure
how to follow this procedure,
seek qualified assistance.
Automobile batteries contain sul-
furic acid. This is poisonous and
highly corrosive. When jump
starting, wear protective glasses
and be careful not to get acid on
yourself, your clothing or on the
vehicle.
Do not attempt to jump start the vehicle if the discharged battery
is frozen or if the electrolyte level
is low; the battery may rupture or
explode.
WARNING - Battery
Never attempt to check the elec-
trolyte level of the battery as this
may cause the battery to rupture or
explode causing serious injury.

What to do in an emergency
Jump starting procedure
1. Make sure the booster battery is 12-volt and that its negative terminal is
grounded.
2. If the booster battery is in another vehicle, do not allow the vehicles totouch.
3. Turn off all unnecessary electrical loads.
4. Connect the jumper cables in the exact sequence shown in the illustration.First connect one end of a jumper
cable to the positive terminal of the
jump start connector (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 ter-
minal of the booster battery (3), then
the other end to the negative terminal
of the jump start connector (4). Do not
connect it to or near any part that
moves when the engine is cranked.
Do not allow the jumper cables to con-
tact anything except the correct battery
terminals or the correct ground. Do not
lean over the battery 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 vehi-
cle with the discharged battery.
If the cause of your battery discharging is
not apparent, you should have your vehi-cle checked by an authorized HYUNDAI dealer.
Push-starting
Vehicles equipped with automatic trans-
mission cannot be push-started.
Follow the directions in this section for
jump-starting.CAUTION - Battery cables
Do not connect the jumper cable
from the negative terminal of the
booster battery to the negative ter-minal of the discharged battery.This can cause the discharged bat- tery to overheat and crack, releas-
ing battery acid.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the shift lever in P and set the parking brake. If the air conditioning is
on, turn it off.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do notopen 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 operat-
ing. 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 vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop).
5. If the water pump drive belt is broken 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 tem-
perature has returned to normal. Then,if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-heating happens again, call an author-
ized HYUNDAI dealer 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 prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized HYUNDAI dealer.

Always check the TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle toensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly.
✽✽
NOTICE
If the TPMS, Low Tire Pressure tell-
tale do not illuminate for 3 seconds
when the ignition switch is turned to
the ON position or engine is run-
ning, or if they remain illuminated
after coming on for approximately 3
seconds, take your car to your near-
est authorized HYUNDAI dealer
and have the system checked.
Low tire pressure tell- tale
Low tire pressure posi- tion telltale
When the tire pressure monitoring
system warning indicators are illumi-
nated, one or more of your tires is
significantly under-inflated. The lowtire pressure position telltale (supple-mental) will indicate which tire is sig-
nificantly under-inflated by illuminat-ing the corresponding position on theLCD screen (if equipped).
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 the
spare tire. The Low Tire Pressure and Position
telltale will remain on until you have
the low pressure tire repaired and
replaced on the vehicle.
✽✽
NOTICE
The spare tire is not equipped with a
tire pressure sensor.
CAUTION
In winter or cold weather, the low tire pressure telltale may beilluminated if the tire pressurewas adjusted to the recom- mended tire inflation pressurein warm weather. It does notmean your TPMS is malfunction- ing because the decreased tem-perature leads to a proportionallowering of tire pressure.
When you drive your vehiclefrom a warm area to a cold area or from a cold area to a warmarea, or the outside temperatureis greatly higher or lower, you should check the tire inflationpressure and adjust the tires tothe recommended tire inflation pressure.

Maintenance
OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAIdealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties 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 coolant reser-
voir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
WARNING - Maintenance
work
Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near theengine or cooling fans.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

effort or looseness in the steering
wheel, or change in its straight-aheadposition.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling 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 oper- ation of your transmission occurs,
check the transmission fluid level.
Check automatic transmission P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-mal).

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 fre-quent oil and filter changes are required. Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically forproper tension and adjusted as neces-
sary. 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 exces-
sive amount of foreign matter accumu-
lates 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 con-
nections for leakage and damage. Have
an authorized HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.

Maintenance
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap iscorrectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.Air cleaner filter
A Genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced. Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (3.8L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI 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 maintenance
schedule. Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately. Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4specification.
