Additional Safety Precautions
Passengers should not move out of
or change seats while the vehicle is
moving. A passenger who is not wearing
a seat belt during a crash or emergency
stop can be thrown against the inside of
the vehicle, against other occupants, or
be ejected from the vehicle.
Do not use any accessories on seat
belts. Devices claiming to improve
occupant comfort or reposition the seat
belt can reduce the protection provided
by the seat belt and increase the chance
of serious injury in a crash.
Do not modify the front seats.
Modification of the front seats could
interfere with the operation of the
supplemental restraint system sensing
components or side air bags.
Do not place items under the front
seats. Placing items under the front seats
could interfere with the operation of the
supplemental restraint system sensing
components and wiring harnesses.
Do not cause impact to the doors.
Impact to the doors when the Engine
Start/Stop button is in the ON or START
position may cause the air bags to
inflate.
Modifications to accommodate
disabilities. If you require modification
to your vehicle to accommodate a
disability, contact Genesis Customer
Care at 844 340-9741
Adding equipment to or modifying
your air bag equipped vehicle
If you modify your vehicle by changing
your vehicle’s frame, bumper system,
front end or side sheet metal or ride
height, this may affect the operation of
your vehicle’s air bag system.
Air Bag Warning Labels
ORS032085N
Air bag warning labels, required by the
U.S. National Highway Traffic Safety
Administration (NHTSA), are attached
to alert the driver and passengers of
potential risks of the air bag system. Be
sure to read all of the information about
the air bags that are installed on your
vehicle in this Owners Manual.

revolutions per minute (RPM).
Use the tachometer to select the correct
shift points and to prevent lugging and/
or over-revving the engine.
NOTICE
Do not operate the engine within the
tachometer's RED ZONE. This may
cause severe engine damage.
Engine coolant temperature gauge
ORS042008NORS042008N
ORS042009NORS042009N
This gauge indicates the temperature
of the engine coolant when the Engine
Start/Stop button is in the ON position.
NOTICE
If the gauge pointer moves beyond the
normal range area toward the “H (Hot)”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “If the Engine
Overheats” section in chapter 8.
WARNING
Never remove the engine coolant
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could cause severe burn. Wait until
the engine is cool before adding coolant
to the reservoir.

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.

Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake
& Brake Fluid warning light illuminates
with the parking brake released, it
indicates that the brake fluid level is
