Blade Inspection
Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.
To prevent damage to the wiper
blades, arms or other compo-
nents, do not:
• Use gasoline, kerosene, paint
thinner, or other solvents on or
near them.
• Attempt to move the wipers
manually.
• Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been
known to make the windshield diffi-
cult to clean.
Blade Replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
• In order to prevent damage to
the hood and the wiper arms, the
wiper arms should only be lifted
when in the top wiping position.
• Always return the wiper arms to
the windshield before driving.
The use of a non-specified wiper
blade could result in wiper mal-
function and failure.
Front windshield wiper service
positions
1. Within 20 seconds of turning off
the engine, lift and hold the wiper
lever up to the MIST position for
about 2 seconds until the wipers
move to the top wipe position.
2. At this time you can lift the wipers
off the windshield.
3. Gently put the wipers back down
onto the windshield.
4. Turn the wipers to any ON position
to return the wipers to the bottom
resting position.

Battery Recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.
AGM battery
• Absorbent Glass Matt (AGM)
batteries are maintenance-free
and we recommend that the
AGM battery be serviced by an
authorized retailer of Genesis
Branded products. For charging
your AGM battery, use only fully
automatic battery chargers that
are specially developed for AGM
batteries.
• When replacing the AGM bat-
tery, we recommend that you
use parts for replacement from
an authorized retailer of Genesis
Branded products.
• Do not open or remove the cap
on top of the battery. This may
cause leaks of internal elec-
trolyte that could result in
severe injury.
NOTICE
Always follow these instruc-
tions when recharging your
vehicle's battery to avoid the
risk of SERIOUS INJURY or
DEATH from explosions or acid
burns:
• Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and press the Engine Start/
Stop button to the OFF posi-
tion.
• Keep all flames, sparks, or
smoking materials away from
the battery.
• Always work outdoors or in an
area with plenty of ventilation.
• Wear eye protection when
checking the battery during
charging.
• The battery must be removed
from the vehicle and placed in
a well ventilated area.
• Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin boiling violently.
WARNING

Tire Replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1/16 inch (1.6 mm) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
To reduce the risk of DEATH or
SERIOUS INJURY:
• Replace tires that are worn,
show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, and
traction.
• Always replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle's Anti-Lock Brake System
(ABS) resulting in a serious
accident.
• It is best to replace all four
tires at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tires as a pair.
Replacing just one tire can
seriously affect your vehicle's
handling.
• Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, Genesis Branded
Vehicle recommends that
tires be replaced after six (6)
years of normal service.
• Heat caused by hot climates
or frequent high loading con-
ditions can accelerate the
aging process. Failure to fol-
low this warning may cause
sudden tire failure, which
could lead to a loss of vehicle
control resulting in an acci-
dent.
