Introduction
Gasoline engine
Unleaded
For Europe
For the optimal vehicle performance,
we recommend you use unleaded
gasoline which has an octane rating
of RON (Research Octane Number)
95 / AKI (Anti Knock Index) 91 or
higher. (Do not use methanol blend-
ed fuels.)
You may use unleaded gasoline with
an octane rating of RON 91~94/AKI
87~90 but it may result in slight per-
formance reduction of the vehicle.
Except Europe
Your new Hyundai vehicle is
designed to use only unleaded fuel
having an Octane Rating of RON
(Research Octane Number) 91 / AKI
(Anti-Knock Index) 87 or higher. (Do
not use methanol blended fuels.)
Your new vehicle is designed to
obtain maximum performance with
UNLEADED FUEL, as well as mini-
mize exhaust emissions and spark
plug fouling.
FUEL REQUIREMENTS
WARNING
• Do not "top off" after the noz-
zle automatically shuts off
when refueling.
• Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel is detrimental
to the catalytic converter and
will damage the engine control
system’s oxygen sensor and
affect emission control.
Never add any fuel system
cleaning agents to the fuel tank
other than what has been speci-
fied. (Consult an authorized
HYUNDAI dealer for details.)

Pre-Safe Seat belt (PSB)
(if equipped)
The purpose of the pre-safe seat belt
is to prevent passengers from getting
hurt by tightening the seat belt right
before a collision or dangerous
maneuver.The pre-safe seat belt warning will
turn on if there is a problem with your
pre-safe seat belt.
Have the system checked if:
• The light does not turn on briefly
when you press the engine
start/stop button to the ON posi-
tion.
• The light stays on after illumination
for approximately 3 seconds.
• The light comes on while the vehi-
cle is in motion.In order to maximize the safety of the
passenger, the pre-safe seat belt
system operates as below
• The seat belt is tightened when:
- The vehicle senses a collision
- Emergency braking situation
occurs
- Losing control of the vehicle
- The passenger leans to one side
• The seat belt vibrates when:
- The vehicle senses a object too
near the vehicle
- The Lane Departure Warning
System (if equipped) detects the
vehicle has moved out of its lane
Other functions are tightening a loose
seat belt after vehicle speed is over
40 km/h (25 mph) and winding a
loose seat belt after unfastening the
seat belt.

CAUTION
The pre-safe seat belt activates
only when the passenger is
wearing his/her seat belt.
CAUTION
Do not be surprised when the
seat belt vibrates. It's not a mal-
function but a warning for your
safety.

Safety features of your vehicle
In addition, do not place front-facing
child restraints in the front passen-
ger’s seat either. If the front passen-
ger air bag inflates, it could cause
serious or fatal injuries to the child.Air bag warning light
The purpose of the air bag warning
light in your instrument panel is to
alert you of a potential problem with
your air bag - Supplemental
Restraint System (SRS).
When the ignition switch is turned
ON, the warning light should illumi-
nate for approximately 6 seconds,
then go off.
Have the system checked if:
• The light does not turn on briefly
when you turn the engine
start/stop button to the ON posi-
tion.• The light stays on after illuminating
for approximately 6 seconds.
• The light comes on while the vehi-
cle is in motion.
• The light blinks when the engine
start/stop button is in ON position.
WARNING
• Extreme Hazard! Do not use a
rearward facing child restraint
on a seat protected by an air
bag in front of it!
• Never put a child restraint in
the front passenger’s seat. If
the front passenger air bag
inflates, it can cause serious
or fatal injuries.
• When children are seated in
the rear outboard seats of a
vehicle equipped with side
and/or curtain air bags, be
sure to install the child
restraint system as far away
from the door side as possible,
and securely lock the child
restraint system in position.
Inflation of side and/or curtain
air bags could cause serious
injury or death to an infant or
child.

FUEL FILLER LID
OVI049024
OVI043025N
WARNING - Refueling
• 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.
• Do not "top off" after the noz-
zle automatically shuts off
when refueling.
• Always check that the fuel cap
is installed securely to pre-
vent fuel spillage in the event
of an accident.

Features of your vehicle
Emergency fuel filler lid release
If the fuel filler lid does not open
using the remote fuel filler lid
release, you can open it manually by
pulling the handle outward slightly.
(Continued)
• When refueling, always shut
the engine off. Sparks pro-
duced by electrical compo-
nents related to the engine
can ignite fuel vapors causing
a fire. Once refueling is com-
plete, check to make sure the
filler cap and filler door are
securely closed, before start-
ing the engine.
• 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.
Automotive fuel is highly
flammable and can, when
ignited, result in fire.
• 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.CAUTION
• Make sure to refuel your vehi-
cle according to the "Fuel
requirements" suggested in
section 1.
• If the fuel filler cap requires
replacement, use only a gen-
uine 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.
• Do not spill fuel on the exteri-
or surfaces of the vehicle. Any
type of fuel spilled on painted
surfaces may damage the
paint.
• After refueling, make sure the
fuel cap is installed securely
to prevent fuel spillage in the
event of an accident.
CAUTION
Do not pull the handle exces-
sively, otherwise the luggage
area trim or release handle may
be damaged.

Parking Brake & Brake
Fluid Warning Light
This warning light illuminates:
• Once you set the ignition switch or
Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3
seconds
- It remains on if the parking brake
is applied.
• When the parking brake is applied.
• When 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
reservoir is low.If the brake fluid level in the reservoir
is low:
1. Drive carefully to the nearest safe
location 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"
in chapter 7). Then check all brake
components for fluid leaks. If any
leak on the brake system is still
found, the warning light remains
on, or the brakes do not operate
properly, do not drive the vehicle.
In this case, we recommend that
you have the vehicle towed to an
authorized HYUNDAI dealer and
inspected.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.
With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure are
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.
