VEHICLE MODIFICATIONS
• This vehicle should not be modified. Modification of your vehicle could affect its
performance, safety or durability and may even violate governmental safety and
emissions regulations.
• In addition, damage or performance problems resulting from any modification may
not be covered under warranty.
• If you use unauthorized electronic devices, it may cause the vehicle to operate
abnormally, wire damage, battery discharge and fire. For your safety, do not use
unauthorized electronic devices.
NOTICE
All warning sounds (e.g. welcome/good-bye sound, virtual engine sound) are
generated from the interior amplifiers. If necessary, we recommend you to purchase
Genesis Part to replace an interior amplifier. Any unauthorized product may cause a
malfunction of the interior amplifiers.
VEHICLE BREAK-IN PROCESS
• Do not race the engine.
• While driving, keep your engine speed (rpm, or revolutions per minute) between
2,000 rpm and 4,000 rpm.
• Do not maintain a single speed for long periods of time, either fast or slow. Varying
engine speed is needed to properly break-in the engine.
• Avoid hard stops, except in emergencies, to allow the brakes to seat properly.
NOTICE

VEHICLE DATA COLLECTION AND EVENT DATA RECORDERS
This vehicle is equipped with an event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist in understanding how a
vehicle’s systems performed. The EDR is designed to record data related to vehicle
dynamics and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by the EDR under normal
driving conditions and no personal data (e.g., name, gender, age, and crash location)
are recorded. However, other parties, such as law enforcement, could combine the
EDR data with the type of personally identifying data routinely acquired during a crash
investigation.
To read data recorded by an EDR, special equipment is required, and access to the
vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special equipment, can read the information if
they have access to the vehicle or the EDR.

To help achieve proper engine and powertrain performance and durability, use only
lubricants of the proper quality. The correct lubricants also help promote engine
efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.

that you use fluid that conform to specifications.
*3 : If the front/rear differential is submerged, visit an authorized retailer of Genesis Branded
products to replace the differential oil.
*4 : If the above recommended specification oil is not available, SAE 0W-30 grade synthetic
oil can be used. If mineral oil or semi-synthetic oil is used, it is a severe maintenance
condition in terms of engine oil change

Carrying long/narrow cargo
ORG3030009N
Additional cargo space is provided to
accommodate long/narrow cargo (skis,
poles, etc.) not able to fit properly in the
trunk when closed.
1. Pull the armrest down.
2. Pull the cover down while pushing the
release lever down.
NOTICE
• Be careful when loading cargo
through the rear passenger seats
to prevent damage to the vehicle
interior.
• When both the armrest and the
panel, which is locates between
the rear seatback and the trunk, are
folded down, put back the panel first
before folding back the arm rest. If
not, the panel knobs and the armrest
knobs may interfere with each other
and get damaged.
CAUTION
• Make sure the engine is off, the
vehicle is shifted to P (Park) and the
parking brake is applied whenever
loading or unloading cargo. The
vehicle may move if the shift lever
is inadvertently moved to another
position.
• When cargo is loaded through the
rear passenger seats, ensure the
cargo is properly secured to prevent
it from moving while driving.
WARNING
Cargo should always be secured to
prevent it from being thrown about the
vehicle in a collision and causing injury
to the vehicle occupants. Do not place
objects in the rear seats, since they
cannot be properly secured and may hit
the front seat occupants in a collision.

Safety System
3-66
ORG3030047
Just before impact, drivers often brake
heavily. Such heavy braking lowers the
front portion of the vehicle causing it
to “ride” under a vehicle with a higher
ground clearance. Air bags may not
inflate in this “underride” situation
because deceleration forces that are
detected by sensors may be significantly
reduced by such “underride” collisions.
ORG3030048
Front air bags may not inflate in
rollover accidents because front air bag
deployment would not provide additional
occupant protection.
Information
With rollover sensor
The side and curtain air bags and front
center air bag may inflate in a rollover
situation, when it is detected by the
rollover sensor.
ORG3030049
Air bags may not inflate if the vehicle
collides with objects such as utility poles
or trees, where the point of impact is
concentrated and the collision energy is
absorbed by the vehicle structure.
