Information
Make sure to refuel your vehicle
according to the "Fuel Requirements"
suggested in the Introduction chapter.
Do not spill fuel on the exterior
surfaces of the vehicle. Any type
of fuel spilled on painted sur-
faces may damage the paint.
If the fuel filler cap requires
replacement, use only a genuine
HYUNDAI cap or the equivalent
specified for your vehicle. An
incorrect fuel filler cap can
result in a serious malfunction
of the fuel system or emission
control system.
NOTICE
i
(Continued)
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.
(Continued)
(Continued)
Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
(Continued)
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.
When refueling, always move
the 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.

Battery State of Charge (SOC)
gauge
This gauge indicates the remaining
hybrid battery power. If the SOC is
near the "L (Low)" level, the vehicle
automatically operates the engine to
charge the battery. However, if the
Service Indicator ( ) and
Malfunction Indicator Lamp (MIL)
( ) turn on when the SOC gauge
is near the "L (Low)" level, have the
vehicle be checked by an authorized
HYUNDAI dealer.
❈The actual cluster in the vehicle
may differ from the illustration.Never try to start the vehicle if the
fuel tank is empty. In this condi-
tion, the engine cannot charge the
high voltage battery of the hybrid
system. If you try to start the vehi-
cle when the fuel is empty, the
high voltage battery will become
discharged and be damaged.

do not operate properly, do not
drive the vehicle. Have the vehicle

Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail.

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 driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.Parking Brake & Brake Fluid
Warning Light
Driving the vehicle with a warn-
ing 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 low.
