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.

Tire Pressure Monitoring System
WARNING
Over-inflation or under-inflation can
reduce tire life, adversely affect vehicle
handling, and lead to sudden tire failure
that may cause loss of vehicle control
resulting in an accident.
Each tire, including the spare (if
provided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard
or tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on
a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating
properly. The TPMS malfunction
indicator is combined with the low
tire pressure telltale. When the system
detects a malfunction, the telltale will
flash for approximately one minute and
then remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that
prevent the TPMS from functioning
properly.
Always check the TPMS malfunction
telltale after replacing one or more tires
or wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
NOTICE
If any of the below happens, have
the system checked by an authorized
retailer of Genesis Branded products.
1. The Low Tire Pressure Telltale/ TPMS Malfunction Indicator does not
illuminate for 3 seconds when the
Engine Start/Stop button is pressed
to the ON position or when the
engine is running.
2. The TPMS Malfunction Indicator remains illuminated after blinking for
approximately 1 minute.
3. The Low Tire Pressure Position Telltale remains illuminated.

Emergency Towing
„Front
OIK080018
„Rear
OIK080020
If towing is necessary, we recommend
you have it done by an authorized
retailer of Genesis Branded products or a
commercial tow truck service.
If towing service is not available in
an emergency, your vehicle may be
temporarily towed using a cable or chain
secured to the emergency towing hook
at the front (or rear) of the vehicle.
Use extreme caution when towing the
vehicle with a cable or chain. A driver
must be in the vehicle to steer it and
operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a short
distance and at low speeds. Also, the
wheels, axles, power train, steering
and brakes must all be in good working
condition.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
precautions:

[ Press the Engine Start/Stop button
to the ACC position so the steering
wheel is not locked.

[ Shift the gear to N (Neutral).

[ Release the parking brake.

[ Depress the brake pedal with more
force than normal as you will have
reduced braking performance.

[ More steering effort will be required
because the power steering system
will be disabled.

[ Use a vehicle heavier than your own to
tow your vehicle.

[ The drivers of both vehicles should
communicate with each other
frequently.

[ Before emergency towing, check that
the hook is not broken or damaged.

[ Fasten the towing cable or chain
securely to the hook.

[ Do not jerk the hook. Apply steady
and even force.

Information

[ As it is normal for engine oil to be consumed during driving, the engine oil level should
be checked on regular basis.

[ The engine oil change interval for normal operating conditions is based on the use of
the recommended engine specification. If the recommended engine oil specification
is not used, then replace the engine oil according to the maintenance schedule under
severe operating conditions.

[ For 2.0 T-GDI engine : The vehicle may be e uipped with the Oil ife Management
System that predicts engine oil life based on the driver s driving history and alerts the
driver to change engine oil.
- If the deterioration of the engine oil increases depending on the driver s driving
severity, the remaining oil life alert appears on the instrument cluster before the
normal engine oil replacement interval. ave the engine oil and filter changed by an
authori ed distributor of Genesis Branded product.
- Oil ife Management System works when the recommended engine oil is used.
So, if recommended engine oil is not used, replace the engine oil according to the
maintenance schedule under severe usage condition.
Also, check the amount of engine oil regularly as this system assumes that the engine
oil is being filled normally.
- Always reset the remaining engine oil life whenever the engine oil is changed.
Otherwise, The indication of remaining Oil life in the Oil ife Management System
may not be accurate.
To reset the Oil Change Reminder, select RESET from the infotainment system
screen. Then, select Yes when the message Changed engine oil Press Yes to reset
