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 use is normal). At least monthly:
[
Check coolant level in the engine
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 headlamp alignment.

[ Check muffler, exhaust pipes, shields and clamps.

WARNING
Never remove the engine
coolant cap and/or inverter
coolant cap or the drain plug
while the engine and radiator
are hot. Hot coolant and steam
may blow out under pressure,
causing serious injury.
Turn the vehicle off and wait until the
engine cools down. Use extreme care
when removing the engine coolant
cap and/or inverter coolant cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure is
released from the cooling system. When
you are sure all the pressure has been
released, press down on the cap, using
a thick towel, and continue turning
counterclockwise to remove it.
Information
The engine coolant and/or inverter coolant level is influenced by the hybrid system
temperature. Before checking or refilling
the engine coolant and/or inverter coolant, turn the hybrid vehicle off.
WARNING
The electric motor for the cooling fan
may continue to operate or start up
when the engine is not running and
can cause serious injury. Keep hands,
clothing and tools away from the
rotating fan blades of the cooling fan.
Always turn off the vehicle unless the
vehicle has to be inspected with the engine on. Be cautious as the cooling
fan may operate if the negative (-)
battery terminal is not disconnected.
WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while driving.

Checking the Hybrid Starter &
Generator (HSG) Belt
We recommend that you have the
Hybrid Starter & Generator (HSG) belt
inspected or replaced according to the
Maintenance Schedule in this chapter by
an authorized HYUNDAI dealer.
CAUTION
When the HSG belt is worn out or
damaged, replace the belt.
Otherwise, it may cause engine
overheating or battery discharge.
WARNING

[ Turn the vehicle off while you inspect
the engine or Hybrid Starter &
Generator (HSG) belt. Otherwise it
may result in serious injury.

[ Keep hands, clothing etc. away from
the Hybrid Starter & Generator (HSG) belt.
Checking the Brake Fluid Level
OTMH090010
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 the specified
brake 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 brake system be checked by an
authorized HYUNDAI dealer.
WARNING
If the brake system requires frequent
additions of fluid this could indicate
a leak in the brake system. We
recommend that the vehicle be
inspected by an authorized HYUNDAI
dealer.
