Driving your vehicle
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 sev-
eral 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 speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way 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.
i
Utility vehicles have a signifi-
cantly higher rollover rate than
other types of vehicles. To pre-
vent rollovers or loss of control:
• Take corners at slower speeds
than you would with a passen-
ger vehicle.
• Avoid sharp turns and abrupt
maneuvers.
• Do not modify your vehicle in
any way that you would raise
the center of gravity.
• Keep tires properly inflated.
• Do not carry heavy cargo on
the roof.
WARNING
In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. Make sure all
passengers are wearing their
seat belts.

The severe weather conditions of winter quickly wear out tires and cause
other problems. To minimize winter driving problems, you should take the fol-
lowing suggestions:
Snow or Icy Conditions
You need to keep sufficient distance between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid acceleration, sudden brake applica-
tions, and sharp turns are potentially very hazardous practices. During decel-
eration, use engine braking to the fullest extent. Sudden brake applications on
snowy or icy roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it may be necessary to use snow tires or
to install tire chains on your tires.
Always carry emergency equipment. Some of the items you may want to carry
include tire chains, tow straps or chains, a flashlight, emergency flares, sand,
a shovel, jumper cables, a window scraper, gloves, ground cloth, coveralls, a
blanket, etc.
Snow tires
We recommend you use snow tires when road temperature is below 45°F
(7°C). Refer to the below chart, and mount the recommended snow tire for
your vehicle.
If you mount snow tires on your vehicle, make sure to use the same inflation
pressure as the original tires. However, if you mount 245/45R19 size tire on
the rear, the tire inflation pressure should maintain 35psi. Mount snow tires on
all four wheels to balance your vehicle's handling in all weather conditions.
The traction provided by snow tires on dry road may not be as high as your
vehicle's original equipment tires. Check with the tire dealer for maximum
speed recommendations.
Information
Do not install studded tires without first checking local, state and municipal reg-
ulations for possible restrictions against their use.

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
AutoSock
®installed. If you hear the
fabric snow chains contacting the
body or chassis, stop and tighten
them. If they still make contact, 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
AutoSock
®.
When using AutoSock
®(fabric
snow chain):
• Wrong size fabric snow chains
or improperly installed fabric
snow chains can damage your
vehicle's brake lines, suspen-
sion, body and wheels.
• If you hear noise caused by fabric
snow chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
• To prevent body damage,
retighten the fabric snow 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 if
necessary
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.
NOTICE

5-156
Driving your vehicle
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized retailer of Genesis
Branded products and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.
Do not let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to happen
when there is an accumulation of
snow or ice around or near the rear
brakes or if the brakes are wet. If
there is a risk the parking brake may
freeze, apply it only temporarily while
you put the gear in P and block the
rear wheels so the car cannot roll.
Then release the parking brake.
Do not let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering compo-
nents is not obstructed.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.

If you Have a Flat Tire While
Driving
If a tire goes flat while you are driv-
ing:
• Take your foot off the accelerator
pedal and let the vehicle slow
down while driving straight ahead.
Do not apply the brakes immedi-
ately 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 Doesn't Turn
Over or Turns Over Slowly
• 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.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle.See instructions for
"Jump Starting" provided in this
chapter.
Push or pull starting the vehicle
may cause the catalytic converter
to overload which can lead to
damage to the emission control
system.
If the Engine Turns Over
Normally but Doesn't Start
Check the fuel level and add fuel if
necessary.
If the engine still does not start, have
your vehicle checked by an author-
ized retailer of Genesis Branded
products.

What to do in an emergency
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 sec-
ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals
or the correct ground. Do not
lean over the battery when mak-
ing connections.
11. Start the engine of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. 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 min-
utes runtime to fully recharge it. If
vehicle is run for less, the battery
may not restart. If you continue to
have problem, have your author-
ized retailer of Genesis Branded
products test the battery.
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.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, neg-
ative (-) 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).
Push-Starting
Vehicles equipped with automatic
transmission cannot be push-start-
ed.
Follow the directions in this chapter
for jump-starting.

If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. 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 condi-
tioning is ON, turn it OFF.
3. If engine coolant is running out
under the vehicle or steam is com-
ing 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.4. Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (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
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 seri-
ous injury.
WARNING

6-8
What to do in an emergency
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. 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 overheat-
ing. If overheating happens again,
call an authorized retailer of
Genesis Branded products for
assistance.
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.
NOTICE
Your vehicle is
equipped with a pres-
surized coolant
reserve tank. NEVER
remove the radiator
cap, drain plug and heater hose
connector cap (refer to the
below picture) 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 remov-
ing the coolant reserve tank
cap. Wrap a towel or thick rag
around it, and turn it counter-
clockwise slowly to release
some of the pressure from the
system. Step back while the
pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.
