Checking the Brake Fluid
Level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.
If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, have
the brake system checked by an
authorized retailer of Genesis
Branded products.• Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result.
• Brake fluid, which has been
exposed to open air for an
extended time should NEVER be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
• Do not use the wrong kind of
brake fluid. A few drops of min-
eral based oil, such as engine
oil, in your brake system can
damage brake system parts.
Information
Use only the specified brake fluid
(refer to "Recommended Lubricants
and Capacities" in chapter 8).

NOTICE
BRAKE FLUID
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. Have the vehicle
inspected by an authorized
retailer of Genesis Branded
products.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.

WASHER FLUID
Checking the Washer Fluid
Level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
• Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
shield and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
• Do not allow sparks or flame
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
• Do not drink washer fluid and
avoid contact with skin.
Washer fluid is harmful to
humans and animals.
• Keep washer fluid away from
children and animals.

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.

Tire Care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
TIRES AND WHEELS
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
• Inspect your tires monthly for
proper inflation as well as
wear and damage.
• The recommended cold tire
pressure for your vehicle can
be found in this manual and
on the tire label located on the
driver’s side center pillar.
Always use a tire pressure
gauge to measure tire pres-
sure. Tires with too much or
too little pressure wear
unevenly causing poor han-
dling.
• Check the pressure of the
spare every time you check
the pressure of the other tires
on your vehicle.
• Replace tires that are worn,
show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering) control, or
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.

Maintenance
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. "Cold tires" means the
vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Warm tires normally exceed recom-
mended cold tire pressures by 4 to 6
psi (28 to 41 kPa). Do not release air
from warm tires to adjust the pres-
sure or the tires will be under-inflat-
ed. For recommended inflation pres-
sure, refer to "Tire and Wheels" in
chapter 8.• Under-inflation results in exces-
sive wear, poor handling and
reduced fuel economy. Wheel
deformation is also possible.
Keep your tire pressures at the
proper levels. If a tire frequently
needs refilling, have it checked by
an authorized retailer of Genesis
Branded products.
• Over-inflation produces a harsh
ride, excessive wear at the cen-
ter of the tire tread, and a greater
possibility of damage from road
hazards.
NOTICE
Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-
ods at high speeds.
WARNING

7-40
Maintenance
Disc brake pads should be inspected
for wear whenever tires are rotated.
Information
The front tire size is different from the
rear tire size. So when you rotate tires,
check the tire and wheel size.
Wheel Alignment and Tire
Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
Improper wheel weights can dam-
age your vehicle's aluminum
wheels. Use only approved wheel
weights.
NOTICE
i
Do not use the compact spare
tire for tire rotation.

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.

Maintenance
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
Wheel Replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire Traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
Tire Sidewall Labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tire in
case of a recall. The original tire should be
repaired or replaced as soon as
possible to avoid failure of the
spare and loss of vehicle con-
trol resulting in an accident. The
compact spare tire is for emer-
gency use only. Do not operate
your vehicle over 50 mph (80
km/h) when using the compact
spare tire.
