Introduction
DANGER
DANGER indicates a hazardous
situation which, if not avoided, will
result in death or serious injury.
WARNING
WARNING indicates a hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTION
CAUTION indicates a hazardous
situation which, if not avoided, could
result in minor or moderate injury.
NOTICE
NOTICE indicates a situation which,
if not avoided, could result in vehicle
damage.
FUEL REQUIREMENTS
Petrol engine
Unleaded
Your new 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 minimize exhaust
emissions and spark plug fouling.
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 specified (We recommend
that you consult an authorized
HYUNDAI dealer for details.)
WARNING
• Do not “top off” after the nozzle
automatically shuts off when
refueling.
• Always check that the fuel cap is
installed securely to prevent fuel
spillage in the event of an accident.

The tachometer indicates the
approximate number of engine
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.
Fuel Gauge
OIB044114OIB044114
„„Type AType A
„„Type BType B
OBI3040005OBI3040005
This gauge indicates the approximate
amount of fuel remaining in the fuel
tank.
i Information
• The fuel tank capacity is given in
chapter 2.
• 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.
WARNING
Running out of fuel can expose vehicle
occupants to danger.
You must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the “E
(Empty)” level.
NOTICE
Avoid driving with a very low fuel
level. Running out of fuel could cause
the engine to misfire damaging the
catalytic converter.

Electric Power Steering
(EPS) 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 and then goes off.
• When there is a malfunction with the
EPS.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
Malfunction Indicator
Lamp (MIL)
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 and then goes off.
• When there is a malfunction with the
emission control system.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
NOTICE
- Malfunction Indicator Lamp (MIL)
Driving with the Malfunction Indicator
Lamp (MIL) on may cause damage to
the emission control systems which
could effect drivability and/or fuel
economy.
NOTICE
- Petrol Engine
If the Malfunction Indicator Lamp
(MIL) illuminates, potential catalytic
converter damage is possible which
could result in loss of engine power.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer as soon as
possible.
NOTICE
- Diesel Engine
If the Malfunction Indicator Lamp
(MIL) blinks, some error related to the
injection quantity adjustment occurs
which could result in loss of engine
power, combustion noise and poor
emission.
In this case, we recommend that
you have the engine control system
inspected by an authorized HYUNDAI
dealer.

NOTICE
- Engine Oil Pressure Warning Light
• If the engine does not stop
immediately after the Engine Oil
Pressure Warning Light is illuminated,
severe damage could result.
• If the warning light stays on while the
engine is running, it indicates that
there may be serious engine damage
or malfunction. In this case,
1. Stop the vehicle as soon as it is safe
to do so.
2. Turn off the engine and check the
oil level. If the oil level is low, fill
the engine oil to the proper level.
3. Start the engine again. If the
warning light stays on after the
engine is started, turn the engine
off immediately. In this case, we
recommend that you have the
vehicle inspected by an authorized
HYUNDAI dealer.
Low Fuel Level Warning
Light
This warning light illuminates:
When the fuel tank is nearly empty.
If the fuel tank is nearly empty, add fuel
as soon as possible.
NOTICE
- Low Fuel Level
Driving with the Low Fuel Level
warning light on or with the fuel level
below “E (Empty)” can cause the
engine to misfire and damage the
catalytic converter (if equipped).

If you have a flat tire while
driving
If a tire goes flat while you are driving:
• Take your foot off the accelerator
pedal and let the vehicle slow down
while driving straight ahead. Do not
apply the brakes immediately or
attempt to pull off the road as this
may cause loss of vehicle control
resulting in an accident. When the
vehicle has slowed to such a speed
that it is safe to do so, brake carefully
and pull off the road. Drive off the
road as far as possible and park on
firm, level ground. If you are on a
divided highway, do not park in the
median area between the two traffic
lanes.
• When the vehicle is stopped, press
the hazard warning flasher button,
move the shift lever into N (Neutral,
for Automated manual transmission)
or neutral (for manual transmission
vehicle), apply the parking brake, and
place the ignition switch in the LOCK/
OFF position.
• Have all passengers get out of the
vehicle. Be sure they all get out on the
side of the vehicle that is away from
traffic.
• When changing a flat tire, follow the
instructions provided later in this
chapter.
IF THE ENGINE WILL NOT
START
If the engine doesn’t turn over
or turns over slowly
• Be sure the for Automated manual
transmission or N (Neutral) if it is a
vehicle. The engine starts only when
the shift lever is in N (Neutral).
• Check the battery connections to be
sure they are clean and tight.
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to start
it. This could cause damage to your
vehicle.
See instructions for “Jump Starting”
provided in this chapter.
WARNING
Push or pull starting the vehicle may
cause the catalytic converter to
overload which can lead to damage to
the emission control system.
If the engine turns over normally
but doesn’t start
• Check the fuel level and add fuel if
necessary.
If the engine still does not start, we
recommend that you call an authorized
HYUNDAI dealer for assistance.

Maintenance
Operating precautions for catalytic
converters (if equipped)
WARNING
Fire
• A hot exhaust system can ignite
flammable items under your vehicle.
Do not park, idle, or drive the vehicle
over or near flammable objects, such
as grass, vegetation, paper, leaves,
etc.
• The exhaust system and catalytic
system are very hot while the engine
is running or immediately after the
engine is turned off. Keep away from
the exhaust system and catalytic, you
may get burned. Also, do not remove
the heat sink around the exhaust
system, do not seal the bottom of the
vehicle or do not coat the vehicle for
corrosion control. It may present a
fire risk under certain conditions.Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
• Use only UNLEADED FUEL for petrol
engine.
• Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
• Do not misuse or abuse the engine.
Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off.
• Do not operate the engine at high idle
speed for extended periods (5 minutes
or more).
• Do not modify or tamper with any
part of the engine or emission
control system. All inspections and
adjustments must be made by an
authorized HYUNDAI dealer.
• Avoid driving with a extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
catalytic converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
