Information
Make sure to refuel your vehicle according
to the "Fuel Requirements" suggested in
the Introduction chapter. Do not spill fuel on the exterior sur-
faces of the vehicle. Any type of fuel
spilled on painted surfaces may
damage the paint.
If the fuel filler cap requires replace- ment, use only a genuine HYUNDAI
cap or the equivalent specified for
your vehicle. An incorrect fuel filler
cap can result in a serious malfunc-
tion of the fuel system or emission
control system.
NOTICE
i
(Continued)
If a fire breaks out during refuel-
ing, leave the vicinity of the vehi-
cle, and immediately contact the
manager of the gas station and
then contact the local fire depart-
ment. Follow any safety instruc-
tions they provide.
If pressurized fuel sprays out, it
can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an acci-
dent.

Maintenance
Automatic Transmission Fluid
(if equipped)
Automatic transmission fluid should not
be checked under normal usage condi-
tions. 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.
Automatic transmission fluid color is
basically red.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker. This is a normal condition and
you should not judge the need to
replace the fluid based upon the
changed color.
Dual Clutch Transmission
Fluid (if equipped)
Inspect the dual clutch transmission fluid
according to the maintenance schedule.
Manual Transmission Fluid
(if equipped)
Inspect the manual transmission fluid
according to 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/Clutch Fluid
Check brake/clutch fluid level in the
brake/clutch fluid reservoir. The level
should be between the MIN and the MAX
marks on the side of the reservoir. Use
only hydraulic brake/clutch fluid conform-
ing to DOT 3 or DOT 4 specification.
Parking Brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
Exhaust Pipe and Muffler
Visually inspect the exhaust pipes, muf-
fler and hangers for cracks, deterioration,
or damage. Start the engine and listen
carefully for any exhaust gas leakage.
Tighten connections or replace parts as
necessary.
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 the engine
off, check for excessive free-play in the
steering wheel. Check the linkage for
bends or damage. Check the dust boots
and ball joints for deterioration, cracks, or
damage.
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 nec-
essary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and con-
nections for leakage and damage.
NOTICE
The use of a non-specified fluid
could result in transmission mal-
function and failure. Use only the
specified automatic transmission
fluid (refer to "Recommended
Lubricants and Capacities" in
chapter 8).
