Engine coolant temperature gauge
OIK040009
This gauge indicates the temperature
of the engine coolant when the Engine
Start/Stop button is in the ON position.
NOTICE
If the gauge pointer moves beyond the
normal range area toward the “H (Hot)”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “If the Engine
Overheats” section in chapter 8.
WARNING
Never remove the engine coolant
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could cause severe burn. Wait until
the engine is cool before adding coolant
to the reservoir.
Fuel gauge
OJX1049032
This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information

[The fuel tank capacity is given in
chapter 2.

[ The fuel gauge is supplemented by
a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.

[ On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in
the tank.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Shift the vehicle to P (Park), and apply the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
4. Check for coolant leaking from the radiator, hoses or under the vehicle. (If
the air conditioning has been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop the engine immediately and call the
nearest authorized retailer of Genesis
Branded products for assistance.
WARNING
Never remove the radiator cap,
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 engine off and wait until the
engine cools down. Use extreme care
when removing the radiant cap or
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.
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost,
carefully add coolant to the reservoir
to bring the fluid level in the reservoir
up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If
overheating happens again, call an
authorized retailer of Genesis Branded
products for assistance.
CAUTION

[Serious loss of coolant indicates a
leak in the cooling system and should
be checked as soon as possible by
an authorized retailer of Genesis
Branded products.

[ When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant slowly
in small quantities. It may require
several refilling cycles to properly
fill the engine cooling system. If
necessary, an authorized retailer of
Genesis Branded products should be
consulted to perform this task.

Maintenance9-6
Owner Maintenance Schedule
When you stop for fuel:

[ Check the coolant level in the engine
coolant reservoir or the liquid-cooled
intercooler 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 engine is hot. This may
result in coolant being blown out of the
opening and cause serious burns and
other injuries.
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.

The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic Transmission Fluid
Automatic transmission fluid should
not be checked under normal usage
conditions, the Automatic transmission
fluid should be changed by an authorized
retailer of Genesis Branded products
according to the maintenance schedule.
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.

ENGINE COOLANT
The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the
factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season and
before traveling to a colder climate.
Checking the Coolant Level
OIK090007
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled
between the MAX and the MIN marks on
the side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring the
level to the MAX mark, but do not overfill.
If frequent additions are required, see an
authorized retailer of Genesis Branded
products for a cooling system inspection.

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
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 antifree e mix is the
easiest to mix together as it will be the
same uantity of each. It is suitable to
use for most temperature ranges of -31 F
(-35 C) and higher.
Changing Coolant
we recommend that the coolant 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 before refilling the
coolant to prevent the coolant from
overflowing into engine parts, such as
the alternator.
