Maintenance
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
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
TemperatureMixture 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
Have coolant be changed by an
authorized retailer of Genesis Branded
products 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 or liquid-cooled intercooler
coolant cap before refilling the
coolant to prevent the coolant from
overflowing into engine parts, such as
the alternator.

Maintenance
High-pressure washing
[ When using high-pressure washers,
make sure to maintain sufficient
distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
[ Do not spray the camera, sensors or
its surrounding area directly with a
high pressure washer. Shock applied
from high pressure water may cause
the device to not operate normally.
[ Do not bring the nozzle tip close to
boots (rubber or plastic covers) or
connectors as they may be damaged
if they come into contact with high
pressure water.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see
if they have been affected by water
before getting on the road. If braking
performance is impaired, dry the
brakes by applying them lightly while
maintaining a slow forward speed.
NOTICE
[ Do not use strong soap, chemical
detergents or hot water, and do not
wash the vehicle in direct sunlight
or when the body of the vehicle is
warm.
[ Be careful when washing the side
windows of your vehicle.
[ Especially, with high-pressure water,
water may leak through the windows
and wet the interior.
[ To prevent damage to the plastic
parts, do not clean with chemical
solvents or strong detergents.
NOTICE
ORS091047
[ Water washing in the engine
compartment including high
pressure water washing may cause
the failure of electrical circuits
located in the engine compartment.
[ Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
NOTICE
Matte paint finish vehicle (if equipped)
Automatic car wash which uses rotating
brushes should not be used as this can
damage the surface of your vehicle. A
steam cleaner which washes the vehicle
surface at high temperature may cause
the oil to adhere and leave stains that is
difficult to remove.
Use a soft cloth (for example, microfiber
towel or sponge) when washing your
vehicle and dry with a microfiber towel.
When you hand wash your vehicle, you
should not use a cleaner that finishes
with wax.
