Owner Maintenance
WARNING Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience or
the proper tools and equipment to do the
work, we recommend that it is done by an
authorized HYUNDAI dealer. ALWAYS
follow these precautions for performing
maintenance work:
• Park your vehicle on level ground. Shift the vehicle to P (Park), apply the
parking brake, and press the Start/Stop
button to the OFF position.
• Block the tires (front and back) to prevent the vehicle from moving.
Remove loose clothing or jewelry that
can become entangled in moving parts.
• Keep flames, sparks, or smoking materials away from the battery and
motor related parts.

WARNING Make sure to turn the Start/Stop button to
the OFF position to shut down the vehicle
before performing maintenance work on
the vehicle.

The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer 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 vehicle
checks are generally not covered by
warranties and you may be charged for
labor, parts and lubricants used. The electric control system in the vehicle
may cause malfunction or other negative
impact on the artificial heart and the
artificial internal organs. Be sure to
inquire the impact of the electric control
system on the artificial organs from the
medical product corporation.
Owner Maintenance Schedule
When you stop for charging:
• Check the coolant level in the coolant
reservoir.
• Check the windshield washer fluid level.
• Check for low or under-inflated tires.
WARNING Be careful when checking your coolant
level if the motor compartment is hot.
This may result in coolant being blown
out of the opening and cause serious
burns and other injuries.

While operating your 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 gear shift occurs,
check the shift gear fluid level.
• Check the shift gear P (Park) function.
• Check the parking brake.

signals and hazard warning flashers.
• Check the inflation pressures of all tires including the spare for tires that are

damaged.
