Air conditioning system operation
tips
If the vehicle has been parked indirect 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 the
recirculated air to the fresh outside
air position.
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 lower speed.
System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter
replaced by an authorized retailer of
Genesis Branded products accord-
ing to the maintenance schedule. If
the car is being driven in severe con-
ditions such as dusty or rough roads,
more frequent air conditioner 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.

Using All Wheel Drive (AWD)
The All Wheel Drive (AWD) System
delivers engine power to the front
and rear wheels for maximum trac-
tion. AWD is useful when extra trac-
tion is required, such as when driving
on slippery, muddy, wet, or snow-
covered roads.
If the system determines there is a
need for addition traction, engine
power will automatically be distrib-
uted to all four wheels.
Information
• Do not drive in water if the level ishigher than the bottom of the vehi-
cle.
• Check your brake condition once you are out of mud or water.
Depress the brake pedal several
times as you move slowly until you
feel normal braking return.
• Shorten your scheduled mainte- nance interval if you drive in off-
road conditions such as sand, mud
or water (see "Maintenance Under
Severe Usage Conditions" in chap-
ter 7).
• Make sure that an AWD vehicle is towed by flatbed tow truck.

If the AWD warning light ( )
stays on the instrument cluster,
your vehicle may have a mal-
function with the AWD system.
When the AWD warning light
( ) illuminates have your
vehicle checked by an author-
ized retailer of Genesis Branded
products as soon as possible.
WARNING
To reduce the risk of SERIOUS
INJURY or DEATH:
Do not drive in conditions that
exceed the vehicles intended
design such as challenging
off-road conditions.
Avoid high speeds when cor- nering or turning.
Do not make quick steering wheel movements, such as
sharp lane changes or fast,
sharp turns.
(Continued)
(Continued)
The risk of a rollover is great-ly increased if you lose con-
trol of your vehicle at highway
speeds.
Loss of control often occurs if two or more wheels drop off
the roadway and the driver
over steers to reenter the
roadway.
In the event your vehicle leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.
Always drive safely and use caution when driving an AWD
vehicle.

Chain Installation
When installing AutoSock®(fabric
snow chain), follow the manufactur-
er's instructions and mount them as
tightly as possible. Drive slowly (less
than 20 mph (30 km/h)) with chains
installed. If you hear the chains con-
tacting the body or chassis, stop and
tighten them. If they still make con-
tact, slow down until the noise stops.
Remove the AutoSock
®(fabric snow
chain) as soon as you begin driving
on cleared roads.
When mounting AutoSock
®(fabric
snow chain), park the vehicle on
level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emer-
gency warning device behind the
vehicle (if available).
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing tire
chains.
When using AutoSock
®(fabric
snow chain):
Wrong size chains or improperly installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
If you hear noise caused by chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage, retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
AutoSock
®is a Registered trade-
mark of AutoSock.
Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
retailer of Genesis Branded prod-
ucts.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized retailer of Genesis
Branded products or a service sta-
tion.

Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, have it done by an author-
ized retailer of Genesis Branded
products.
ALWAYS follow these precau-
tions for performing mainte-
nance work:
• Park your vehicle on level
ground, move the shift lever
into the P (Park) position,
apply the parking brake, place
the Engine Start/Stop button
in the OFF position.
Block the tires (front and back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
elry that can become entan-
gled in moving parts.
If you must run the engine during maintenance, do so
out doors or in an area with
plenty of ventilation.
Keep flames, sparks, or smok- ing materials away from the
battery and fuel-related parts.
WARNING
Touching metal parts
Do not touch metal parts
(including strut bars) while the
engine is operating or hot.
Doing so could result in serious
personal injury. Turn the engine
off and wait until the metal parts
cool down to perform mainte-
nance work on the vehicle.
