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 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. Shift the gear to P
(Park), apply the parking
brake, and press the Engine
Start/Stop button to 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.

When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windshield washer fluid level.
Check the tire for low or under- inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
