Jump starting procedure
1. Position the vehicles close enough that the jumper cables will reach, but
do not allow the vehicles to touch.
2. Avoid fans or any moving parts in the engine compartment at all times, even
when the vehicles are turned off.
3. Turn off all electrical devices such as radios, lights, air conditioning, etc.
Put the vehicles in P (Park) and set
the parking brakes. Turn both vehicles
OFF.

4. Connect the jumper cables in the exact sequence shown in the
illustration. First connect one jumper
cable to the red, positive (+) jumper
terminal of your vehicle (1).
5. Connect the other end of the jumper cable to the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
6. Connect the second jumper cable to the black, negative (-) battery/chassis
ground of the assisting vehicle (3).
7. Connect the other end of the second jumper cable to the black, negative (-)
chassis ground of your vehicle (4).
Do not allow the jumper cables to
contact anything except the correct
battery or jumper terminals or the
correct ground. Do not lean over the
battery when making connections. 8. Start the engine of the assisting
vehicle and let it run at approximately
2,000 rpm for a few minutes. Then
start your vehicle.
If your vehicle will not start after a few
attempts, it probably requires servicing.
In this event please seek qualified
assistance. If the cause of your battery
discharging is not apparent, have your
vehicle checked by an authorized
HYUNDAI dealer.
Disconnect the jumper cables in the
exact reverse order you connected them:
1. Disconnect the jumper cable from the black, negative (-) chassis ground of
your vehicle (4).
2. Disconnect the other end of the jumper cable from the black, negative
(-) battery/chassis ground of the
assisting vehicle (3).
3. Disconnect the second jumper cable from the red, positive (+) battery/
jumper terminal of the assisting
vehicle (2).
4. Disconnect the other end of the jumper cable from the red, positive (+)
jumper terminal of your vehicle (1).

Maintenance8-6
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 if there is any increased
steering effort or looseness in the
steering 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 transmission occurs,
check the transmission fluid level.
• Check the automatic transmission P (Park) function.
• Check the parking brake.
• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after

At least monthly:
• Check coolant level in the engine coolant reservoir.
• Check the operation of all exterior lights, including the brake lights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all tires including the spare for tires that
are worn, show uneven wear, or are
damaged.
• Check for loose wheel lug nuts.
At least twice a year:
(i.e., every Spring and Autumn)
• Check radiator, heater and air conditioning hoses for leaks or
damage.
• Check windshield washer spray and wiper operation. Clean wiper blades
with a clean cloth dampened with
washer a fluid.
• Check headlamp alignment.
• Check muffler, exhaust pipes, shields and clamps.
• Check the seat belts for wear and function.

A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment
near the battery.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved and
immediately consult an authorized
HYUNDAI dealer.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.
• A higher capacity fuse could cause
damage and possibly cause a fire.
• Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.
