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 gear to P (Park) and set 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 engine coolant cap and/or liquid-cooled intercooler 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 coolant cap. Wrap a thick towel around it, and turn it counterclockwise slowly. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, using a thick towel, and continue turning counterclockwise to remove it.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)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.

Checking the Engine Oil Level
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
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 and the wheels blocked.
3. Turn the engine on and warm
the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to return
to the oil pan.
5. Wipe the dipstick clean and re-insert
it fully.

Checking the Engine Oil and
Filter
OIK090122NOIK090122N
• The lubrication, rust prevention,
cooling, and cleaning effect of the
engine oil will gradually degrade
during its use. Have the engine oil
and filter changed by an authorized
retailer of Genesis Branded
products according to the Engine
Oil Change Reminder function or
the Maintenance Schedule at the
beginning of this chapter.
• If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.
• To keep the engine in optimal
condition, use the recommended
engine oil. If the recommended
engine oil and filter are not
used, replace it according to the
maintenance schedule under severe
usage conditions.
• The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
Information
When the oil pressure is low due to
insufficient engine oil, the Engine Oil
Pressure (
) warning light will illuminate.
In addition, the enhanced engine protection
system, which limits the engine’s power is
activated and the Malfunction Indicator
Lamp (
) will illuminate when the vehicle
is driven in this state continuously. When oil
pressure is restored, the Engine Oil Pressure
warning light will turn off and the engine
power will no longer be limited. However,
for gasoline 2.5 turbo engine, when the oil
pressure is restored, the warning light and
the enhanced engine protection system will
turn off after the engine is restarted.
CAUTION
The engine oil is very hot immediately
after the vehicle has been driven and
can cause burns during replacement.
Replace the engine oil after the engine
oil has cooled down.
