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.
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.

Maintenance
Air Cleaner Filter
A Genesis air cleaner filter is recom-
mended when the filter is replaced.
Spark Plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
Inspect for excessive valve noise
and/or engine vibration and adjust if
necessary. Have an authorized retail-
er of Genesis Branded products per-
form the operation.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged

The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Manual Transmission Fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
Automatic Transmission Fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,
the fluid should be changed at an
authorized retailer of Genesis
Branded products in accordance to
the scheduled maintenance at the
beginning of this chapter.Automatic transmission fluid
color is red when new.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker. This is a normal
condition and you should not
judge the need to replace the fluid
based upon the changed color.
The use of a non-specified fluid
could result in transmission mal-
function and failure. Use only the
specified automatic transmission
fluid (refer to "Recommended
Lubricants and Capacities" in
chapter 8).
