Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be inspected
by an authorized HYUNDAI dealer or in a
service station.
To prevent locks from freezing
Spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes, try
to thaw it with a heated key. Carefully use
the heated key to avoid an injury.
Use approved window washer anti-freeze
solution
Add authorized window washer
anti-freeze solution, as specified on the
window washer container. Window
washer anti-freeze solution is available
from an authorized HYUNDAI dealer, and
most vehicle accessory outlets. Do not
use coolant or other types of anti-freeze
solution, to prevent any damage to the
vehicle paint.
Do not let your parking brake freeze
Under some conditions, your parking
brake may freeze in the engaged position.
This is most likely to happen when there is
an accumulation of snow or ice around or
near the rear brakes or the brakes are wet.
When there is the risk that your parking
brake may freeze: temporarily apply the
parking brake with the gear in P (Park),
then block the rear wheels, and then
release the parking brake.Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
may build up under the fenders and
interfere with the steering. When driving
in such conditions during the severe
winter, check underneath the vehicle on a
regular basis, to make sure that the front
wheels and the steering components are
not blocked.
Carry emergency equipment
In accordance with weather conditions,
carry appropriate emergency equipment,
while driving. Some of the items you may
want to carry include tire chains, tow
straps or chains, flashlight, emergency
flares, sand, shovel, jumper cables,
window scraper, gloves, ground cloth,
coveralls, blanket, etc.
Do not place objects or materials in the
motor compartment
Putting objects or materials in the motor
compartment may cause a motor failure.
Such damage is not be covered by the
manufacturer’s warranty.

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.
Hyundai_CE_en_US.book Page 6

• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after use
is normal).
At least monthly:
• Check coolant level in the coolant reservoir.
• Check the operation of all exterior lights, including the stoplights, 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: (for example,
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 fluid.
• Check headlight alignment.
• Check the seat belts for wear and function.
At least once a year:
• Clean body and door drain holes.
• Lubricate door hinges and hood hinges.
• Lubricate door and hood locks and latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate shift gear linkage and controls.
• Clean the battery (12 V) and terminals.
• Check the brake fluid level.
