Introduction
A020101ABH-EU
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.
3.8 engine
Your new vehicle is designed to use only
unleaded fuel having an octane number
((R+M)/2) of 87 (Research Octane
Number 91) or higher.
5.0 engine
Your new vehicle is designed to use only
unleaded fuel having an octane number
((R+M)/2) of 87 or higher.
For improved vehicle performance, pre-
mium unleaded fuel with a Pump Octane
Rating of 91 (Research Octane Number
95) or higher is recommended.
A020103AUN-EU
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems, check malfunction indicator light or
damage and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.
Vehicle damage or drivability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10%
ethanol.
2. Gasoline or gasohol containing
methanol.
3. Leaded fuel or leaded gasohol.
FUEL REQUIREMENTS
CAUTION
Never add any fuel system cleaning
agents to the fuel tank other than
what has been specified. (Consult
an authorized HYUNDAI dealer for
details.)
WARNING
• Do not "top off" after the nozzle
automatically shuts off when
refueling.
Tighten the cap until it clicks one
time, otherwise the Malfunction
Indicator Light “ ” will illumi-
nate.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.

Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
E120300AEN
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
E120400ABH
Change to "winter weight" oil if
necessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
E120500AUN
Check spark plugs and ignition
system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING- Tire chains
The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h)
or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps,
holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked-
wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Stop driving and retighten the
chains any time you hear them
hitting the vehicle.

What to do in an emergency
2. When the car is stopped, turn on your
emergency hazard flashers, set the
parking brake and put the shift lever in
P.
3. Have all passengers get out of the car.
Be sure they all get out on the side of
the car that is away from traffic.
4. When changing a flat tire, follow the
instruction provided later in this sec-
tion.
F020300AEN
If engine stalls while driving
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your
vehicle will not start, contact an
authorized HYUNDAI dealer or seek
other qualified assistance.
F030100BBH
If engine doesn't turn over or
turns over slowly
1. Be sure the shift lever is in N (Neutral)
or P (Park) and the emergency brake
is set.
2. Check the battery connections to be
sure they are clean and tight.
3. Turn on the interior light. If the light
dims or goes out when you operate the
starter, the battery is discharged.
4. Check the starter connections to be
sure they are securely tightened.
5. Do not push or pull the vehicle to start
it. See instructions for "Jump starting".
F030200ABH
If engine turns over normally but
does not start
1. Check fuel level.
2. With the ignition switch in the LOCK
position, check all connectors at igni-
tion coils and spark plugs. Reconnect
any that may be disconnected or
loose.
3. If the engine still does not start, call an
authorized HYUNDAI dealer or seek
other qualified assistance.
IF THE ENGINE WILL NOT START
WARNING
If the engine will not start, do not
push or pull the car to start it. This
could result in a collision or cause
other damage.

Maintenance

Maintenance
G050900AUN
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
G051000AEN
Valve clearance (3.8L)
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
G051100AUN
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
G051200AUN
Coolant
The coolant should be changed at the
intervals specified in the maintenance
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 HYUNDAI
dealer in accordance to the scheduled
maintenance at the beginning of this
chapter.
✽ ✽
NOTICE
Automatic transmission fluid color is
basically red.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
G051500AUN
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
G051600AUN
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 4
specification.
Never mix different types of fluid.
G051700AUN
Parking brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.CAUTION
