out doors or in an area with
plenty of ventilation.

Maintenance
Checking the Engine Oil Level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set. If possible, block the
wheels.
3. Turn the engine on and allow the
engine to reach normal operating
temperature.
4. Turn the engine off and wait about
five minutes for the oil to return to
the oil pan.
5. Pull the dipstick out, wipe it clean,
and re-insert it fully.
6. Pull the dipstick out again and
check the level. The level should
be between F and L.7. If it is near or at L, add enough oil
to bring the level to F.
Use only the specified engine oil
(refer to "Recommended
Lubricants and Capacities" in
chapter 8).
To prevent damage to your
engine:
• Do not overfill with engine oil.
Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
• Do not spill engine oil when
adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately.

Recommended engine 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 alu-
minum engine parts and must be
protected by an ethylene-glycol
with phosphate based coolant to
prevent corrosion and freezing.
• Do not use alcohol or methanol
coolant or mix them with the spec-
ified 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:
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 and higher.

-49°F (-45°C) 60 40
Never remove the
radiator 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 remov-
ing the radiator 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.

Maintenance
Changing Engine Coolant
Have coolant changed by an author-
ized retailer of Genesis Branded
products according to the
Maintenance Schedule at the begin-
ning of this chapter.
To prevent damage to engine
parts, put a thick towel around the
radiator cap before refilling the
coolant to prevent the coolant
from overflowing into engine
parts, such as the alternator.
NOTICE
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.
WARNING
When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning
counterclockwise to remove it.
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 engine
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 discon-
nected.
