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 engineoil
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.
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 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.
NOTICE

5-108
Driving your vehicle
Check spark plugs and ignitionsystem
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 washeranti-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 brakefreeze
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 selector lever 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 ormaterials 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 the Engine Doesn't Turn
Over or Turns Over Slowly
Be sure the shift lever is in N(Neutral) or P (Park). The engine
starts only when the shift lever 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 cableto 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.
