Information
The Power Trunk Lock button will
not work if you press the button when:
- Any door is open.
- The Engine Start/Stop button is notin the OFF position.
- The Smart Key is in the vehicle. Do not close or open the Power
Trunk manually. This may cause
damage to the Power Trunk. If it
is necessary to close or open the
Power Trunk manually when the
battery is drained or disconnect-
ed, do not apply excessive force.
Do not leave the Power Trunk open for a long period of time.
This may drain the battery.
To prevent damage to the trunk lift cylinders and the attached
hardware, always close the trunk
before driving.
Information
In cold and wet climates, trunk lock
and trunk mechanisms may not work
properly due to freezing conditions.
Power trunk non-opening orclosing conditions:
The Power Trunk will not open or
close automatically, when the vehi-
cle is moving more than 1.8 mph (3
km/h).
The Power Trunk can be operated when the engine is not running.
However, the Power Trunk operation
consumes large amounts of vehicle
electric power. To prevent the bat-
tery from draining, do not operate it
excessively (e.g., more than
approximately 10 times repeatedly.)
Do not modify or repair any part of the Power Trunk by yourself. This
must be done by an authorized
retailer of Genesis Branded prod-
ucts.
Before jacking up the vehicle to change a tire or repair the vehicle,
open the Power Trunk. Do not oper-
ate the Power Trunk when the vehi-
cle is raised or this could cause the
Power Trunk to operate improperly.
i
NOTICEi
Never leave children or animals
unattended in your vehicle.
Children or animals might oper-
ate the power trunk that could
result in injury to themselves or
others, or damage to the vehicle.
WARNING
Always keep the trunk lid com-
pletely closed while the vehicle is
in motion. If it is left open or ajar,
poisonous exhaust gases con-
taining carbon monoxide (CO)
may enter the vehicle and seri-
ous illness or death may result.
WARNING
Make sure there are no people
or objects around the trunk
before opening or closing the
Power Trunk. Wait until the trunk
is open fully and stopped before
loading or unloading cargo from
the vehicle.

hear a hissing noise as the pres-
sure inside the tank equalizes.
Place the cap on the fuel filler
door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on
the door. If necessary, spray around the
door with an approved de-icer fluid (do
not use radiator anti-freeze) or move

Gasoline is highly flammable
and explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refueling, note the location of the Emergency
Gasoline Shut-Off, if available,
at the gas station.
Before touching the fuel noz- zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.

WARNING

Convenient features of your vehicle(Continued)
Do not use cellular phones while refueling. Electric cur-
rent and/or electronic interfer-
ence from cellular phones can
potentially ignite fuel vapors
and cause a fire.
Do not get back into a vehicle once you have begun refuel-
ing. You can generate a build-
up of static electricity by
touching, rubbing or sliding
against any item or fabric
capable of producing static
electricity. Static electricity
discharge can ignite fuel
vapors causing a fire. If you
must re-enter the vehicle, you
should once again eliminate
potentially dangerous static
electricity discharge by touch-
ing a metal part of the vehicle,
away from the fuel filler neck,
nozzle or other gasoline
source, with your bare hand.
When using an approved portable fuel container, be
sure to place the container on
the ground prior to refueling.
Static electricity discharge
from the container can ignite
fuel vapors causing a fire.
Once refueling has begun,
contact between your bare
hand and the vehicle should
be maintained until the filling
is complete.
Use only approved portable plastic fuel containers designed
to carry and store gasoline.
(Continued)
(Continued)
When refueling, always movethe shift lever to the P (Park)
position, set the parking
brake, and place the Engine
Start/Stop button to the OFF
position. Sparks produced by
electrical components related
to the engine can ignite fuel
vapors causing a fire.
Do not use matches or a lighter and do not smoke or
leave a lit cigarette in your
vehicle while at a gas station,
especially during refueling.
Do not over-fill or top-off your vehicle tank, which can cause
gasoline spillage.
If a fire breaks out during refu- eling, leave the vicinity of the
vehicle, and immediately con-
tact the manager of the gas
station and then contact the
local fire department. Follow
any safety instructions they
provide.
If pressurized fuel sprays out, it can cover your clothes or
skin and thus subject you to
the risk of fire and burns.
Always remove the fuel cap
carefully and slowly. If the cap
is venting fuel or if you hear a
hissing sound, wait until the
condition stops before com-
pletely removing the cap.
Always check that the fuel cap is installed securely to pre-
vent fuel spillage in the event
of an accident.

Engine coolant temperaturegauge
This gauge indicates the tempera-
ture of the engine coolant when the
Engine Start/Stop button is in the ON
position.
If the gauge pointer moves beyond
the normal range area toward the
"H" position, it indicates overheat-
ing that may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to "If the Engine
Overheats" in chapter 6.
Fuel gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given in
chapter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.
Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire,
damaging the catalytic converter.
