WARNING
Make sure the coolant cap is properly
closed after refilling coolant. Otherwise
the engine could be overheated while
driving.

1. Check if the coolant cap label is straight In front.

2. Make sure that the tiny protrusions inside the coolant cap are securely
interlocked.
Recommended coolant

[When adding coolant, use only
deionized water, distilled water or soft
water for your vehicle and never mix
hard water in the coolant filled at the
factory.

[ An incorrect coolant mixture can
result in severe malfunction or
engine/hybrid system damage.

[ The engine in your vehicle has
aluminum engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to prevent
corrosion and freezing.

[ Do not use alcohol or methanol
coolant or mix them with the specified
coolant.

[ Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixing percentage, refer to the
following table:
Ambient
Temperature Mixture Percentage
(volume)
Antifreeze Water
5°F (-15°C) 35 65
-

13°F (-25°C) 40 60
-31°F (-35°C) 50 50
-49°F (-45°C) 60 40
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of -31°F
(-35°C) and higher.

Changing Coolant
We recommend that coolant be changed
by an authorized HYUNDAI dealer
according to the Maintenance Schedule
at the beginning of this chapter.
WARNING
Do not use engine coolant or antifreeze
in the washer fluid reservoir.
Engine coolant can severely obscure
visibility when sprayed on the
windshield and may cause loss of
vehicle control resulting in an accident.
Engine coolant may also cause damage
to paint and body trim.
NOTICE
To prevent damage to engine parts, put
a thick towel around the engine coolant
cap and/or inverter coolant cap before
refilling the coolant to prevent the
coolant from overflowing into engine
parts, such as the alternator.
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.
WARNING
Do not let brake fluid enter into your
eyes. If brake fluid gets in 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 it will
result in paint damage.

[ NEVER use brake fluid which has
been exposed to open air for an
extended time, as its quality cannot
be guaranteed. It should be disposed
of properly.

[ Do not use the wrong type of brake
fluid. A few drops of mineral based
oil in your brake system can damage
brake system parts.
Information
Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).

usual recommended intervals (Refer
to “Maintenance Under Severe Usage
Conditions” section 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 or the
equivalent speficied for your vehicle.

Blade Inspection
Contamination of either the windshield
or the wiper blades with foreign matter
can reduce the effectiveness of the
windshield wipers.
Common sources of contamination are
insects, tree sap, and hot wax treatments
used by some commercial car washes. If
the blades are not wiping properly, clean
both the window and the blades with a
good cleaner or mild detergent, and rinse
thoroughly with clean water.
NOTICE
To prevent damage to the wiper blades,
arms or other components, do not:

[ Use gasoline, kerosene, paint
thinner, or other solvents on or near
them.

[ Attempt to move the wipers

[ manually.

[ Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been known to
make the windshield difficult to clean.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn or
cracked, and require replacement.
NOTICE
To prevent damage to the wiper arms
or other components, do not attempt to
move the wipers manually.
NOTICE
The use of a non-specified wiper blade
could result in wiper malfunction and
failure.
NOTICE

[In order to prevent damage to the
hood and the wiper arms, the wiper
arms should only be lifted when in
the top wiping position.

[ Always return the wiper arms to the
windshield before driving.

For Best Battery Service
„Luggage compartment
OTMH090021

[ Keep the battery securely mounted.

[ Keep the battery top clean and dry.

[ Keep the terminals and connections
clean, tight, and coated with
petroleum jelly or terminal grease.

[ Rinse any spilled electrolyte from the
battery immediately with a solution of
water and baking soda.

[ If the vehicle is not going to be used
for an extended time, disconnect the
battery cables.
Information

[To check the batteries, open the cover
(B).
For 7-seater, the clips (A) must be
removed first to open the cover.

[ For vehicles with power trunks, note
that the power trunk needs to be reset
after the battery has been replaced. For
more details, refer to “Power Liftgate”
section in chapter 5.
NOTICE
Make sure the battery is installed
securely when the it is replaced. If the
battery vibrates while driving, the case
and electrode plate can be damaged.
Information - For batteries
marked with UPPER and
LOWER
OHI078084L
If your vehicle is equipped with a battery
marked with LOWER (MIN) and UPPER
(MAX) on the side, you should check the
electrolyte level.
The electrolyte level should be between
LOWER (MIN) and UPPER (MAX).
When the electrolyte level is low, add
distilled (or de-mineralized) water. (Never
add sulfuric acids or other electrolyte).
Be careful not to spill distilled (or
demineralized) water over the battery
surface or other adjacent components.
Also, do not overfill the battery cells.
If not, it may corrode the battery or other
components. Finally, securely close the
cell cap. However, we recommend you to
contact an authorized HYUNDAI dealer
for better battery service.
