Checking the brake fluid level
OCN7080006
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition
associated with the wear of the brake
linings.
If the fluid level is excessively low, we
recommend that the system be checked
by an authorized HYUNDAI dealer.
Information
Use only the specified brake fluid. Refer to
“Recommended lubricants and capacities”
in chapter 2.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap.
Information
Clean the filler cap before removing. Use
only DOT4 brake fluid from a sealed
container.
WARNING
Do not allow brake fluid to come in
contact with your eyes. If brake fluid
comes in contact with your eyes, flush
your eyes with clean water for at least
15 minutes and get immediate medical
attention.
NOTICE
• Do not allow brake fluid to contact
the vehicle’s body paint, as paint
damage will result.
• Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
• Don’t put in the wrong kind of fluid. A
few drops of mineralbased oil, such
as engine oil, in your brake system
can damage system parts.
• To maintain the best braking
performance and ABS/ESC
performance, we recommend that
you use genuine brake fluid that
conform to specifications.

ver is firmly
installed.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to “Maintenance Under
Severe Usage Conditions” in this chapter).
NOTICE
• Do not drive with the air cleaner filter
removed. This will result in excessive
engine wear.
• When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake, or damage may
result.
• Use HYUNDAI genuine parts. Use of
non-genuine parts could damage the
engine.

Battery Recharging
WARNING
Always follow these instructions when
recharging your vehicle’s battery to
avoid the risk of SERIOUS INJURY or
DEATH from explosions or acid burns:
• Before performing maintenance or
recharging the battery, turn off all
accessories and place the ignition
switch to the LOCK/OFF position.
• Keep all flames, sparks, or smoking
materials away from the battery.
• Always work outdoors or in an area
with plenty of ventilation.
• Wear eye protection when checking
the battery during charging.
• The battery must be removed from
the vehicle and placed in a well
ventilated area.
• Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin boiling
violently.
• Vehicle is equipped with the
Absorbent Glass Mat (AGM) battery.
Do not charge the AGM battery with
a general charger. It may damage
or explode the AGM battery. Only
charge the AGM battery with a
charger that has AGM battery
setting.
• The negative battery cable must
be removed first and installed last
when the battery is disconnected.
Disconnect the battery charger in the
following order:
1.
Turn o

ff the battery charger main
switch.
2.
Unhook the nega

tive clamp from
the negative battery terminal.
3.
Unhook the positiv

e clamp from
the positive battery terminal.
• Always use a genuine HYUNDAI
approved battery when you replace
the battery.
NOTICE
AGM battery (if equipped)
• Absorbent Glass Matt (AGM)
batteries are maintenance-free
and we recommend that the AGM
battery be serviced by an authorized
HYUNDAI dealer. For charging
your AGM battery, use only fully
automatic battery chargers that
are specially developed for AGM
batteries.
• When replacing the AGM battery,
we recommend that you use parts
for replacement from an authorized
HYUNDAI dealer.
• Do not open or remove the cap on
top of the battery. This may cause
leaks of internal electrolyte that
could result in severe injury.
By jump starting
After a jump start from a good battery,
drive the vehicle for 20-30 minutes
before it is shutoff. The vehicle may
not restart if you shut it off before the
battery had a chance to adequately
recharge. See “Jump Starting” in chapter
7 for more information on jump starting
procedures.
Information
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
Reset items
Items should be reset after the battery
has been discharged or the battery has
been disconnected.
• Auto up/down window (See chapter 5)
• Sunroof (See chapter 5)
• Trip computer (See chapter 4)
• Climate control system (See chapter 5)

Normal Blown
OTM078035
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.
