Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,
as well as minimize exhaust emissions and spark plug fouling.
For the optimal vehicle performance, we recommend you use unleaded gasoline which
has an octane number ((R+M)/2) of 91 (Research Octane Number 95) or higher.
NOTICE
Using unleaded gasoline that is lower than octane number ((R+M)/2) of 91
(Research Octane Number 95) could result in loss of engine power and increase fuel
consumption.
NOTICE
To prevent damage to the engine and engine components, never add any fuel
system cleaning agents to the fuel tank other than what has been specified.
Consult an authorized retailer of Genesis Branded products for additional
information.
WARNING

[Do not “top off” after the nozzle automatically shuts off when refueling.

[ Always check that the fuel cap is installed securely to prevent fuel spillage in the
event of an accident.
Gasoline containing alcohol and methanol
Gasohol, a mixture of gasoline and ethanol (also known as grain alcohol) are being
marketed along with or instead of leaded or unleaded gasoline. For example, “E15” is
a gasohol comprised of 15% ethanol and 85% gasoline. Do not use gasohol containing
more than 15% ethanol, and do not use gasoline or gasohol containing any methanol.
Either of these fuels may cause drivability problems and damage to the fuel system,
engine control system and emission control system.
Discontinue using gasohol of any kind if drivability problems occur. “E85” fuel is
an alternative fuel comprised of 85 percent ethanol and 15 percent gasoline, and is
manufactured exclusively for use in Flexible Fuel Vehicles. “E85” is not compatible
with your vehicle. Use of “E85” may result in poor engine performance and damage
to your vehicle’s engine and fuel system. Genesis Branded Vehicle recommends that
customers do not use fuel with an ethanol content exceeding 15 percent.
NOTICE
To prevent damage to your vehicle’s engine and fuel system:

[Never use gasohol which contains methanol.

[ Never use gasohol containing more than 15% ethanol.

[ Never use leaded fuel or leaded gasohol.

[ Never use “E85” fuel.
Your New Vehicle Limited Warranty does not cover damage to the fuel system or any
performance problems caused by the use of “E85” fuel.

checking or draining any lubricant. This is especially important in dusty or sandy
areas and when the vehicle is used on unpaved roads. Cleaning the plug and dipstick
areas will prevent dirt and grit from entering the engine and other mechanisms that
could be damaged.
Engine oil viscosity (thickness) has an effect on fuel economy and cold weather
operating (engine start and engine oil flowability). Lower viscosity engine oils can
provide better fuel economy and cold weather performance, however, higher viscosity
engine oils are required for satisfactory lubrication in hot weather. Using oils of any
viscosity other than those recommended could result in engine damage.
When choosing an oil, consider the range of temperature your vehicle will be operated
in before the next oil change. Proceed to select the recommended oil viscosity from
the chart.

*1 : Requires < API SN PLUS (or above) Full synthetic> grade engine oil. If a lower grade
engine oil (mineral oil including Semi-synthetic) is used, then the engine oil and engine
oil filter must be replaced as indicated severe maintenance condition.
*2 : For better fuel economy, it is recommended to use the engine oil of a viscosity grade
SAE 5W-30. However, if the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
An engine oil displaying this American Petroleum Institute(API)
Certification Mark conforms to the International Lubricant
Specification Advisory Committee (ILSAC). It is recommended
to only use engine oils that uphold this API Certification Mark.

How does the Air Bags System
Operate?
OIK030110N
The SRS consists of the following
components:
(1) Driver's front air bag module / Driver's knee airbag module
(2) Passenger's front air bag module
(3) Side air bag modules
(4) Curtain air bag modules
(5) Retractor pre-tensioner assemblies
(6) Air bag warning light
(7) SRS control module (SRSCM) /
Rollover sensor
(8) Front impact sensors
(9) Side impact sensors (acceleration)
(10) Side impact sensors (pressure)
(11) Emergency Fastening Device System
(12) Occupant classification system
(13) Front center air bag module

à Front passenger’s air bag OFF lamp is
located on the overhead console. The SRSCM (Supplemental Restraint
System Control Module) continually
monitors all SRS components while
the Engine Start/Stop button is ON to
determine if a crash impact is severe
enough to require air bag deployment or
pre-tensioner seat belt deployment.
SRS warning light
The SRS (Supplemental Restraint System)
air bag w
arning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential problem with your
air bag system, which could include
your side and/or curtain air bags used
for rollover protection (if equipped with
rollover sensor).

Parking brake & Brake fluid
warning light
This warning light illuminates:

[When y
ou set the Engine Start/Stop
button to the ON position.
- The parking brake & brake fluid warning light illuminates for about 3
seconds and will then turn off once
the parking brake is released.

[ Whenever the parking brake is
applied.

[ Whenever the brake fluid level in the
reservoir is low.
- If the warning light illuminates with the parking brake released, it
indicates the brake fluid level in the
reservoir is low.
If the brake fluid level in the reservoir is
low:
1. Drive carefully to the nearest safe loca
tion and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required (For more details,
refer to “Brake Fluid” section in
chapter 9). After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found, or
if the warning light remains on, or if
the brakes do not operate properly, do
not drive the vehicle. Have the vehicle
inspected by an authorized retailer of
Genesis Branded products. Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal br

aking system. This means you
still have braking on two wheels even if
one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
Also, the vehicle will not stop in as short
a distance with only a portion of the
brake system working.
If the brakes fail while you are driving,
shift to a lower gear for additional engine
braking and stop the vehicle as soon as it
is safe to do so.
WARNING
