The hazard warning flasher serves as 
a warning to other drivers to exercise 
extreme caution when approaching, 
overtaking, or passing your vehicle.
It should be used whenever emergency 
repairs are being made or when the 
vehicle is stopped near the edge of a 
roadway.
To turn the hazard warning flasher on 
or off, press the hazard warning flasher 
button with the Engine Start/Stop button 
in any position. The hazard warning 
flasher button is located in the center 
fascia panel. All turn signal lights will 
flash simultaneously.
• The hazard warning flasher operates 
regardless of whether your vehicle is 
running or not.
• The turn signals do not work when the 
hazard flasher is on.
If the Engine Stalls While Driving
• Reduce your speed gradually, keeping 
a straight line. Move cautiously off the 
road to a safe place.
• Turn on your hazard warning flasher.
• Try to start the engine again. If your 
vehicle will not start, contact an 
authorized retailer of Genesis Branded 
products or seek other qualified 
assistance.

If You Have a Flat Tire While 
Driving
If a tire goes flat while you are driving:
• Take your foot off the accelerator 
pedal and let the vehicle slow down 
while driving straight ahead. Do not 
apply the brakes immediately or 
attempt to pull off the road as this 
may cause loss of vehicle control 
resulting in an accident. When the 
vehicle has slowed to such a speed 
that it is safe to do so, brake carefully 
and pull off the road. Drive off the 
road as far as possible and park on 
firm, level ground. If you are on a 
divided highway, do not park in the 
median area between the two traffic 
lanes.
• When the vehicle is stopped, press the 
hazard warning flasher button, shift 
the gear to P (Park), apply the parking 
brake, and press the Engine Start/Stop 
button to the OFF position.
• Have all passengers get out of the 
vehicle. Be sure they all get out on the 
side of the vehicle that is away from 
traffic.
• When changing a flat tire, follow the 
instructions provided later in this 
chapter.
IF THE ENGINE WILL NOT 
START
• Be sure to shift the gear to N (Neutral) 
or P (Park). The engine starts only 
when the gear is in N (Neutral) or P 
(Park).
• Turn on the interior light. If the light 
dims or goes out when you operate 
the starter, the battery is drained.
See instructions for “Jump Starting” 
provided in this chapter.
• Check the fuel level and add fuel if 
necessary.
If the vehicle still does not start, call an 
authorized retailer of Genesis Branded 
products for assistance.
NOTICE
Push or pull starting the vehicle may 
cause the catalytic converter to 
overload which can lead to damage to 
the emission control system.

Jump starting can be dangerous if done 
incorrectly. Follow the jump starting 
procedure in this section to avoid serious 
injury or damage to your vehicle. If in 
doubt about how to properly jump start 
your vehicle, we strongly recommend 
that you have a service technician or 
towing service do it for you.
 WARNING
To prevent SERIOUS INJURY or DEATH 
to you or bystanders, always follow 
these precautions when working near 
or handling the battery:
Always read and follow instructions carefully when 
handling a battery.
Wear eye protection designed to protect the eyes from acid 
splashes.
Keep all flames, sparks, or smoking materials away from 
the battery.
Hydrogen is always present in battery cells, is highly 
combustible, and may explode 
if ignited.
Keep batteries out of reach of children.
Batteries contain sulfuric acid which is highly corrosive. Do 
not allow acid to contact your 
eyes, skin or clothing.If acid gets into your eyes, flush your 
eyes with clean water for at least 15 
minutes and get immediate medical 
attention. If acid gets on your skin, 
thoroughly wash the area. If you feel 
pain or a burning sensation, get medical 
attention immediately.
• When lifting a plastic-cased battery, 
excessive pressure on the case may 
cause battery acid to leak. Lift with a 
battery carrier or with your hands on 
opposite corners.
• Do not attempt to jump start your 
vehicle if your battery is frozen.
• NEVER attempt to recharge the 
battery when the vehicle’s battery 
cables are connected to the battery.
• The electrical ignition system works 
with high voltage.
NEVER touch these components 
with the engine running or when the 
Engine Start/Stop button is in the ON 
position.
Jump starting procedure
 Information
Your vehicle has a battery in the luggage 
compartment, but when you jump start 
your vehicle, use the jumper terminal in 
the engine compartment.
1. Position the vehicles close enough 
that the jumper cables will reach, but 
do not allow the vehicles to touch.
2. Avoid fans or any moving parts in the 
engine compartment at all times, even 
when the vehicles are turned off.
3. Turn off all electrical devices such as 
radios, lights, air conditioning, etc.

the exact sequence shown in the 
illustration. First connect one jumper 
cable to the red, positive (+) jumper 
terminal of your vehicle (1).
8. Connect the other end of the jumper 
cable to the red, positive (+) battery/
jumper terminal of the assisting 
vehicle (2).
9. Connect the second jumper cable to 
the black, negative (-) battery/ chassis 
ground of the assisting vehicle (3).
10. Connect the other end of the second 
jumper cable to the black, negative (-) 
chassis ground of your vehicle (4).
Do not allow the jumper cables to 
contact anything except the correct 
battery or jumper terminals or the 
correct ground. Do not lean over the 
battery when making connections.
11. Start the engine of the assisting 
vehicle and let it run at approximately 
2,000 rpm for a few minutes. Then 
start your vehicle.
12. Keep your vehicle operating for at 
least 30 minutes at idle or driving to 
assure your battery receives enough 
charge to be able to start on its 
own after the vehicle is shut off. A 
complete dead battery may require 
as long as 60 minutes runtime to fully 
recharge it. If vehicle is run for less, 
the battery may not restart. 
If your vehicle will not start after a few 
attempts, it probably requires servicing. 
In this event please seek qualified 
assistance. If the cause of your battery 
discharging is not apparent, have your 
vehicle checked by an authorized retailer 
of Genesis Branded products.

Emergency Situations8-6
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 had 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.
IF THE ENGINE OVERHEATS
Disconnect the jumper cables in the 
exact reverse order you connected them:
1. Disconnect the jumper cable from the 
black, negative (-) chassis ground of 
your vehicle (4).
2. Disconnect the other end of the 
jumper cable from the black, negative 
(-) battery/chassis ground of the 
assisting vehicle (3).
3. Disconnect the second jumper cable 
from the red, positive (+) battery/
jumper terminal of the assisting 
vehicle (2).
4. Disconnect the other end of the 
jumper cable from the red, positive (+) 
jumper terminal of your vehicle (1).
 Information
An inappropriately disposed battery can be harmful to 
the environment and human 
health. Dispose of the battery 
according to your local law(s) or 
regulations.
NOTICE
To prevent damage to your vehicle:
• Only use a 12-volt power supply 
(battery or jumper system) to jump 
start your vehicle.
• Do not attempt to jump start your 
vehicle by push-starting.

 WARNING
Never remove the engine coolant cap and/or water-
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 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.
