conditioning system off if the engine
temperature gauge indicates engine
overheating.
Air conditioning system operation tips

[If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.

[After sufficient cooling has been
achieved, switch back from
recirculation mode to fresh mode.

[To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.

[Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.

[If you operate air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection to the

position and fan speed control to the
lowest speed.

System Maintenance
Cabin air filter
OHI048581L
A : Outside air,
B : Recirculated air,
C : Climate control air filter,
D : Blower,
E : Evaporator core,
F : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
We recommend that the cabin air filter
be replaced by an authorized retailer of
Genesis Branded products according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected at an
authorized retailer of Genesis Branded
products.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized retailer of Genesis Branded
products.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
NOTICE

[The refrigerant system should only
be serviced by trained and certified
technicians to insure proper and safe
operation.

[The refrigerant system should be
serviced in a well-ventilated place.

[The air conditioning evaporator
(cooling coil) shall never be repaired
or replaced with one removed from
a used or salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.

WARNING
Windshield heating
Do not use the
position during
cooling operation in extremely humid
weather. The difference between the
temperature of the outside air and that
of the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection button to the
position
and fan speed control knob to a lower
speed.

[For maximum defrost performance,
set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.

[If warm air to the floor is desired while
defrosting or defogging, set the mode
to the floor-defrost position.

[Before driving, clear all snow and ice
from the windshield, rear window,
side view mirrors and all side
windows.

[Clear all snow and ice from the
hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the
probability of fogging up the inside of
the windshield.
NOTICE
If the engine temperature is still cold
after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.

Paddle Shifter (Manual Shift
Mode)
ORS061009
The paddle shifter allows the driver to
shift gears without taking one’s hands off
the steering wheel.
The paddle shifter operates as follow.

[Pull the [+] or [-] paddle shifter once
to shift up or down one gear and the
system changes from automatic shift
mode to manual shift mode.

[To change back to automatic shift
mode from manual shift mode, do one
of the following:
-Pull the [+] paddle shifter for more
than one second.
-Drive the vehicle under 4 mph (7
km/h)
-Gently depress the accelerator
pedal for more than 6 seconds.
-Rotate the shift dial to the D (Drive)
position.
Information
If the [+] and [-] paddle shifters are pulled
at the same time, gear shift may not occur.
Good Driving Practices

[Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.

[Never shift the gear into P (Park) when
the vehicle is in motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).

[Do not shift the gear to N (Neutral)
when driving. If the gear is shifted to
N (Neutral) while driving, the vehicle
loses the ability to provide engine
braking. Doing so may increase the
risk of an accident.
Also, shifting the gear back to
D (Drive) while the vehicle is
moving may severely damage the
transmission.

[When driving uphill or downhill,
always shift to D (Drive) for driving
forward or shift to R (Reverse) for
driving rearwards. After selecting
D (Drive) or R (Reverse), check the
gear position indicated on the cluster
before driving. If the vehicle moves in
the opposite direction of the selected
gear, the engine may turn off and a
serious accident might occur due to
degraded brake performance.

[Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.

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.

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).
