When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic when
outside temperatures are high. Air
conditioning system operation
when climbing a steep grade or in
high outside ambient temperatures
can cause engine overheating.
Continue to use the fan, but turn
the air 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 recir-
culation 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 win-
dows and sunroof closed.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
• 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 knob or button to
the position and fan speed
control to the lowest speed.
System Maintenance
Cabin air filter
[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 condi-
tioning system.
Have the cabin air filter 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 and/or
if transporting pets or occupants
smoke inside the vehicle, then more
frequent cabin air filter inspections
and changes are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized retailer of Genesis
Branded products.

vide power for mobile telephones or
other devices designed to operate
with vehicle electrical systems. The
devices should draw less than 180 W
(Watts) with the engine running.To prevent damage to the Power
Outlets :
• Use the power outlet only when
the engine is running and
remove the accessory plug after
use. Using the accessory plug
for prolonged periods of time
with the engine off could cause
the battery to discharge.
• Only use 12V electric acces-
sories which are less than 180 W
(Watts) in electric capacity.
• Adjust the air-conditioner or
heater to the lowest operating
level when using the power outlet.
• Close the cover when not in use.
• Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static
and malfunctions in other elec-
tronic systems or devices used
in your vehicle.
• Push the plug in as far as it will
go. If good contact is not made,
the plug may overheat and the
fuse may open.
• Plug in battery equipped electri-
cal/electronic devices with
reverse current protection. The
current from the battery may
flow into the vehicle's electrical/
electronic system and cause
system malfunction.

Information
In situations when the gear needs to be
shifted from P (Park) to N (Neutral)
when the Engine Start/Stop button is
in the OFF position, refer to step 4.
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Shift the vehicle into the P (Park)
position, apply the parking brake,
and place the Engine Start/Stop but-
ton in the OFF position. Take the Key
with you when exiting the vehicle.
Paddle Shifter
(Manual Shift Mode)
The paddle shifter is available when
the shift lever is in the D (Drive) posi-
tion.
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 the automatic shift
mode from manual shift mode, do
one of the following:
• Move the shift lever down toward
the D (Drive) position.
• Gently depress the accelerator
pedal for more than 5 seconds.
• Drive the vehicle under 4 mph (7
km/h).
• Pull and hold the right side paddle
shifter.
Information
If the [+] and [-] paddle shifters are
pulled at the same time, gear shift may
not occur.

• When you stay in the vehicle
with the engine running, be
careful not to depress the
accelerator pedal for a long
period of time. The engine or
exhaust system may overheat
and start a fire.
• The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components.
• Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.

Good Driving Practices
• Never shift from P (Park) or N
(Neutral) to any other position with
the accelerator pedal depressed.
• Never shift 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 move the shift lever to N
(Neutral) when driving. If the shift
lever is moved to N (Neutral) while
driving, the vehicle loses the ability
to provide engine braking. Doing
so may increase the risk of an acci-
dent.
• Driving uphill or downhill, always
shift to D (Drive) when driving for-
ward or to R (Reverse) when driv-
ing backwards, and check the gear
position indicated on the cluster
before driving. If you drive in the
opposite direction of the selected
gear, the engine will turn off and a
serious accident might be occurred
due to the degraded brake per-
formance.
• 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.
• Depressing both accelerator and
brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released.• When driving in Manual shift mode
with the paddle shifter, slow down
before shifting to a lower gear.
Otherwise, the lower gear may not
be engaged if the engine rpms are
outside of the allowable range.
• Always apply the parking brake
when leaving the vehicle. Do not
depend on placing the transmis-
sion in P (Park) to keep the vehicle
from moving.
• Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident.
• Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.

Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
You can still stop your vehicle by
applying greater force to the brake
pedal than typical. The stopping dis-
tance, however, will be longer than
with power brakes.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.
BRAKING SYSTEM
5-21
05
Take the following precautions:
• Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
• When descending down a
long or steep hill, move the
gear shift lever to Manual
Shift Mode and manually
downshift to a lower gear in
order to control your speed
without using the brake pedal
excessively. Applying the
brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
• Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
WARNING

Good Braking Practices
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 products to
pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and 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 driv-
ing, 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 for-
ward. Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Shift
the gear to P (Park), apply the
parking brake, and press the
Engine Start/Stop button to the
OFF.
Vehicles with the parking brake
not fully engaged are at risk for
moving inadvertently and caus-
ing injury to yourself or others.

Driving your vehicle
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take the
below suggestions:
• Drive cautiously and keep 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 unnec-
essary wheel spin.
• Put sand, rock salt, tire chains or
other non-slip materials under the
wheels to provide additional trac-
tion while the vehicle becomes
stuck in ice, snow, or mud.
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 for-
ward 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 accelera-
tor 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.
SPECIAL DRIVING CONDITIONS
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 down-
shifting on slippery surfaces.
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 vehi-
cle, the vehicle can overheat
quickly, possibly causing an
engine compartment fire or
other damage. Try to avoid spin-
ning 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).
WARNING

5-151

Information
The ESC system must be turned OFF
before rocking the vehicle.
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, pos-
sible damage to the transmission,
and tire damage. See "Towing" in
chapter 6.
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 dis-
tance between you and other vehi-
cles, 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 driver's head-
lamps.
• Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
• Avoid staring directly at the head-
lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.
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 follow-
ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
• Turn OFF your 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 tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See "Tire Replacement" in chap-
ter 7.
• Turn on your headlamps to make it
easier for others to see you.
• Driving too fast through large pud-
dles 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 driv-
ing 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 decreas-
es, refer to "Tire Replacement" in
chapter 7.
