Good Braking Practices
WARNING
Whenever leaving the vehicle or
parking, always come to a complete
stop and continue to depress the brake
pedal. Shift the gear to the P (Park)
position, then apply the parking brake,
and press the Engine Start/Stop button
to the OFF position.
Vehicles parked with the parking brake
not applied or not fully engaged may
roll inadvertently and may cause injury
to the driver and others. ALWAYS apply
the parking brake before exiting the
vehicle.
Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop as
quickly if the brakes are wet. Wet brakes
may cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns to
normal. If the braking action does not
return to normal, stop as soon as it is safe
to do so and we recommend that you call
an authorized retailer of Genesis Branded
products for assistance.DO NOT drive with your foot resting on
the brake pedal. Even light, but constant
pedal pressure can result in the brakes
overheating, brake wear, and possibly
even brake failure.
If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while you
slow down. When you are moving slowly
enough for it to be safe to do so, pull off
the road and stop in a safe location.
Keep your foot firmly on the brake pedal
when the vehicle is stopped to prevent
the vehicle from rolling forward.

The Multi-chamber air suspension uses
the air spring containing compressed
air to adjust and maintain the vertical
height of the vehicle both manually or
automatically, according to number of
passengers and load capacity. It also
controls the valve inside the air spring
to adjust stiffness of the air spring and
damper to maximize driving comforts.
Each driving mode provides different
ride comforts.
Vehicle Height Adjustment

[Press the vehicle height adjustment
button to adjust the height. Pressing
the button will raise the vehicle body
and the indicator light illuminates.
Pressing the button again will return
the vehicle height to its original
position and the indicator light turns
off.
[If the vehicle is driving in high speed,
the vehicle height adjustment is set
to automatic mode and the vehicle
height will return to its original
position although you press the
button.
-While above a certain speed, the
height will be automatically set
depending on the driving speed.
-Vehicle height may differ depending
on the drive mode.

[Depending on vehicle condition,
height adjustment will not operate or
stop operating, and the indicator light
blinks.
-When the Multi-chamber air
suspension is malfunctioning
-When the vehicle is lifted up.
-When the vehicle is not stable due
to a sudden brake or acceleration.
-When the air compressor is
overheated.
-When the vehicle is not parked on a
level ground.

[Vehicle height may automatically be
adjusted after 2/4/8/16 hours from
turning off the engine. It is due to the
changes in air temperature.
CAUTION
If the compressor air filter under the
vehicle body is submerged in water,
do not operate the air suspension.
Moisture inflow may damage the
system.

This message is displayed when there is
a malfunction with the Multi-chamber
air suspension system. Have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
CAUTION

[When adjusting vehicle height, check
if there are any obstacles below or
above the vehicle.

[If air inside the suspension is
discharged, a warning message
will be displayed. If so, stop driving
and use a towing vehicle. Since
the vehicle height will be very low,
projections on the road may damage
the vehicle. See ‘Towing when the
air suspension malfunctions’ before
towing the vehicle.
Information

[Operating the air suspension may
cause a little noise when charging and
discharging the air.

[Adjusted vehicle height may vary
depending on the temperature and
surrounding environment.

[When the suspension warning message
is displayed, the system enables safe
mode to prevent secondary failure
and the vehicle performance may be
displayed differently.

[When the vehicle is parked on a slope,
or when the vehicle is in unstable
condition due to sudden acceleration,
deceleration or steering, vehicle height
adjustment becomes temporarily
disabled. If the vehicle escapes from
such dangerous situation, vehicle height
adjustment is enabled again.

[When the vehicle is lifted up with a
lift or jack, height adjustment may be
disabled to protect the system. If the
vehicle engine is started or you start
driving, the function is enabled again.

[Leaving the vehicle parked for long
time may lower the vehicle height. The
vehicle height returns to its original
position when the engine is started.

[If the battery is either overcharged or
discharged, vehicle height adjustment
is disabled to protect the system and a
temporary warning message may be
displayed.

[If the vehicle height adjustment is
operated repeatedly, the function may
be temporarily disabled due to the
overheated compressor. It is to prevent
the breakdown of related parts.

SPECIAL DRIVING CONDITIONS
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the following
precautions:

[Drive cautiously and maintain a longer
braking distance.

[Avoid abrupt braking or steering.

[When your vehicle is stuck in
snow, mud, or sand, use second
gear. Accelerate slowly to avoid
unnecessary wheel spin.

[Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
Downshifting with an automatic
transmission while driving on slippery
surfaces can cause an accident. The
sudden change in tire speed could
cause the tires to skid. Be careful when
downshifting on slippery surfaces.
Rocking the Vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and a forward gear.
Try to avoid spinning the wheels, and do
not race the engine.
To prevent transmission wear, wait until
the wheels stop spinning before shifting
gears. Release the accelerator pedal
while shifting, and press lightly on the
accelerator pedal while the transmission
is in gear. Slowly spinning the wheels in
forward and reverse directions causes a
rocking motion that may free the vehicle.
WARNING
If the vehicle is stuck and excessive
wheel spin occurs, the temperature
in the tires can increase very quickly.
If the tires become damaged, a tire
blow out or tire explosion can occur.
This condition is dangerous - you and
others may be injured. Do not attempt
this procedure if people or objects are
anywhere near the vehicle.
If you attempt to free the vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damage. Try to avoid spinning the
wheels as much as possible to prevent
overheating of either the tires or the
engine. DO NOT allow the vehicle to
spin the wheels above 35 mph
(56 km/h).

6-67
06
Information
The ESC system must be turned OFF
before rocking the vehicle.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage to
the transmission, and tire damage. See
“Towing” section in chapter 8.
Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember:

[Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.

[Adjust your mirrors to reduce the glare
from other drivers’ headlights.

[Keep your headlights clean and
properly aimed. Dirty or improperly
aimed headlights will make it much
more difficult to see at night.

[Avoid staring directly at the headlights
of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to
readjust to the darkness.

6-68
Driving Your Vehicle
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:

[Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.

[Turn OFF your Smart Cruise Control

[Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.

[Be sure your tires have enough tread.
If your tires do not have enough depth
of tire tread, making a quick stop on
wet pavement can cause a skid and
possibly lead to an accident. See “Tire
Tread” section in chapter 9.

[Turn on your headlights to make it
easier for others to see you.

[Driving too fast through large puddles
can affect your brakes. If you must go
through puddles, try to drive through
them slowly.

[If you believe your brakes may be wet,
apply them lightly while driving until
normal braking operation returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the water.
The best advice is SLOW DOWN when
the road is wet.
The risk of hydroplaning increases as the
depth of tire tread decreases, refer to
“Tire Tread” section in chapter 9.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

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.
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 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.

Notes On the Safe Use of the Tire
Mobility Kit
• Park your vehicle at the side of the
road so that you can work with the
Tire Mobility Kit away from moving
traffic.
• To be sure your vehicle will not move,
even when you’re on fairly level
ground, always set your parking brake.
• Only use the Tire Mobility Kit for
sealing/inflation passenger vehicle
tires. Only punctured areas located
within the tread region of the tire can
be sealed using the tire mobility kit.
• Do not use on motorcycles, bicycles
or any other type of tires.
• When the tire and wheel are
damaged, do not use Tire Mobility Kit
for your safety.
• Use of the Tire Mobility Kit may not be
effective for tire damage larger than
approximately 0.16 in. (4 mm).
Please contact the nearest retailer of
Genesis Branded products if the tire
cannot be made roadworthy with the
Tire Mobility Kit.• Do not use the Tire Mobility Kit if a tire
is severely damaged by driving run flat
or with insufficient air pressure.
• Do not remove any foreign objects
such as nails or screws that have
penetrated the tire.
• Provided the vehicle is outdoors,
leave the engine running. Otherwise
operating the compressor may
eventually drain the vehicle battery.
• Never leave the Tire Mobility Kit
unattended while it is being used.
• Do not leave the compressor running
for more than 10 minutes at a time or
it may overheat.
• Do not use the Tire Mobility Kit if the
ambient temperature is below -22°F
(-30°C).
• In case of skin contact with the
sealant, wash the area thoroughly
with plenty of water. If the irritation
persists, seek medical attention.
• In case of eye contact with the
sealant, flush your eyes for at least 15
minutes. If the irritation persists, seek
medical attention.
• In case of swallowing the sealant,
rinse the mouth and drink plenty of
water. However, never give anything
to an unconscious person and seek
medical attention immediately.
• Long time exposure to the sealant
may cause damage to bodily tissue
such as kidney, etc.
