Introduction
Using Fuel Additives (except Detergent Fuel Additives)
Using fuel additives such as:
-Silicone fuel additive
-Ferrocene (iron-based) fuel additive
-Other metallic-based fuel additives
may result in cylinder misfire, poor acceleration, engine stalling, damage to the
catalyst, or abnormal corrosion, and may cause damage to the engine resulting in a
reduction in the overall life of the powertrain.
-The Malfunction Indicator Lamp (MIL) may illuminate.
NOTICE
Damage to the fuel system or performance problem caused by the use of these fuels
or fuel additives may not be covered by your New Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful manganese-based fuel additives such as MMT
(Methylcyclopentadienyl Manganese Tricarbonyl).
Genesis Branded Vehicle does not recommend the use of gasoline containing MMT.
This type of fuel can reduce vehicle performance and affect your emission control
system.
The malfunction indicator lamp on the cluster may come on.
Detergent Fuel Additives
Genesis Branded Vehicle recommends that you use good quality gasolines treated
with detergent additives such as TOP TIER Detergent Gasoline, which help prevent
deposit formation in the engine. These gasolines will help the engine run cleaner and
enhance performance of the Emission Control System. For more information on TOP
TIER Detergent Gasoline, please go to the website (www.toptiergas.com).
For customers who do not use TOP Tier Detergent Gasoline regularly, and have
problems starting or the engine does not run smoothly, detergent-based fuel additives
that you can purchase separately may be added to the gasoline. If TOP TIER Detergent
Gasoline is not available, one bottle of additive added to the fuel tank at every 8,000
miles or 12 months is recommended.
Additives are available from your authorized retailer of Genesis Branded products
along with information on how to use them. Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle in another country, be sure to:

[Observe all regulations regarding registration and insurance.

[Determine that acceptable fuel is available.

Maintenance
NOTICE

[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 battery,
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 electrolyte that
could result in severe injury.

[Lithium battery (if equipped)
-Do not jump start other vehicles.
The lithium polymer type battery
installed in your vehicle may be
damaged.
-Do not connect external electrical
devices to the battery.
-When replacing the lithium
polymer battery, have the battery
replaced at an authorized retailer
of Genesis Branded products.
By jump starting
After a jump start from a good battery,
drive the vehicle for 20-30 minutes
before it is shutoff. The vehicle may
not restart if you shut it off before the
battery had a chance to adequately
recharge. See “Jump Starting” in chapter
8 for more information on jump starting
procedures.
Information
An inappropriately disposed
battery can be harmful to the
environment and human health.
Dispose of the battery according
to your local law(s) or regulation.
Reset Items
The following items may need to be reset
after the battery has been discharged or
the battery has been disconnected.

WARNING
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 pressure. Tires with too
much or too little pressure wear
unevenly causing poor handling.

[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 effectiveness, steering
control, or traction.

[ALWAYS replace tires with the
same size, type, construction and
tread pattern as each tire that
was originally supplied with this
vehicle. Using tires and wheels
other than the recommended
sizes could cause unusual
handling characteristics, poor
vehicle control, or negatively
affect your vehicle’s Anti-Lock
Brake System (ABS) resulting in a
serious accident.
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.
ORS012024N
All specifications (sizes and
pressures) can be found on a label
attached to the driver’s side center
pillar.
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
recommended cold tire pressures
by 4 to 6 psi (28 to 41 kPa). Do not
release air from warm tires to adjust
the pressure or the tires will be
under-inflated. For recommended
inflation pressure, refer to “Tire and
Wheels” section in chapter 2.
