Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust
emissions and spark plug fouling.
Your new vehicle is designed to use only
unleaded fuel having an octane number
((R+M)/2) of 87 (Research Octane
Number 91) or higher. (Do not use
methanol blended fuels)
NOTICE
To prevent damage to the engine and
engine components, never add any fuel
system cleaning agents to the fuel tank
other than what has been specified.
Consult an authorized HYUNDAI dealer
for additional information.
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.
FUEL REQUIREMENTS
Throughout this manual DANGER,
WARNING, CAUTION, NOTICE and the

Recommended SAE Viscosity
Number
CAUTION
Always be sure to clean the area around
any filler plug, drain plug, or dipstick
before checking or draining any
lubricant. This is especially important
in dusty or sandy areas and when the
vehicle is used on unpaved roads.
Cleaning the plug and dipstick areas
will prevent dirt and grit from entering
the engine and other mechanisms that
could be damaged.Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils
can provide better fuel economy and
cold weather performance, however,
higher viscosity engine oils are required
for satisfactory lubrication in hot
weather.
Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.

*1 : For better fuel economy, it is
recommended to use the engine oil
of a viscosity grade 0W-20 (API Latest
(SN PLUS)). However, if the engine oil is
not available in your country, select the
proper engine oil using the engine oil
viscosity chart.

SRS warning light
The SRS (Supplement Restraint System)
air bag w
arning light on the instrument
panel displays the air bag symbol
depicted in the illustration. The system
checks the air bag electrical system for
malfunctions. The light indicates that
there is a potential malfunction with your
air bag system, which could include your
side and curtain air bags used for rollover
protection.
WARNING
If your SRS malfunctions, the air bag
may not inflate properly during an
accident increasing the risk of serious
injury or death.
If any of the following conditions occur,
your SRS is malfunctioning:
• The light does not turn on for
approximately six seconds when the
Engine Start/Stop button is in the ON
position.
• The light stays on after illuminating
for approximately six seconds.
• The light comes on while the vehicle
is in motion.
• The light blinks when the engine is
running.
Have an authorized HYUNDAI dealer
inspect the SRS as soon as possible if
any of these conditions occur. During a frontal collision, sensors will
detect the vehicle’s deceleration. If the
rate of deceleration is high enough, the
control unit will inflate the front air bags.
The front air bags help protect the driver
and front passenger by responding to
frontal impacts in which seat belts alone
cannot provide adequate restraint. When
needed, the side air bags help provide
protection in the event of a side impact
or rollover.
• Air bags are activated (able to inflate
if necessary) when the Engine Start/
Stop button is in the ON position or
approximately within 3 minutes after
ignition off.
• Air bags inflate in the event of certain frontal or side collisions to help
protect the occupants from serious
physical injury.
• Generally, air bags are designed to inflate based upon the severity of
a collision, its direction, etc. These
two factors determine whether
the sensors produce an electronic
deployment/inflation signal.
• The front air bags will completely inflate and deflate in an instant. It is
virtually impossible for you to see the
air bags inflate during an accident. It is
much more likely that you will simply
see the deflated air bags hanging out
of their storage compartments after
the collision.

This warning light illuminates:
• When you place the ignition switch to the ON position.
-
The air bag warning light illuminates
for about 6 seconds and then turns
off when all checks have been
performed
• The air bag warning light will remain illuminated if there is a malfunction
with the Safety Restraint System (SRS)
air bag operation.
In this case, have the vehicle

Parking Brake & Brake Fluid
Warning Light
This warning light illuminates:
• When you place the ignition switch to the ON position.
-
The parking brake light illuminates
for about 3 seconds and will then
turn off once the parking brake is
released.
• Whenever the parking brake is applied.
• Whenever the brake fluid level in the reservoir is low.
- If the warning light illuminates with the parking brake released, it
indicates that the brake fluid level in
the reservoir is low.
If the brake fluid level in the reservoir is
low:
1. Drive carefully to the nearest safe loca
tion and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately
and add fluid as required (For more
information, refer to "Brake Fluid" in
chapter 8). After adding brake fluid,
check all brake components for fluid
leaks. If a brake fluid leak is found, or
if the warning light remains on, or if
the brakes do not operate properly, do
not drive the vehicle. Have the vehicle
inspected by an authorized HYUNDAI
dealer. Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal br
aking systems. This means
you still have braking on two wheels even
if one of the dual systems should fail.
With only one of the dual systems
working, more than normal pedal travel
and greater pedal pressure is required to
stop the vehicle.
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.
WARNING
Parking Brake & Brake Fluid Warning
Light
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
low.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.

Charging System Warning
Light
When this warning light illuminates while
the engine is running, the battery is not

Have the vehicle inspected by an
authorized HYUNDAI dealer as soon as
possible.
Engine Oil Pressure Warning
Light
This warning light illuminates:
When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe loca
tion and stop your vehicle.
2. Turn the engine off and check the engine oil level (For more
information, refer to "Engine Oil" in
chapter 8). If the level is low, add oil
as required.
If the warning light remains on after
adding oil or if oil is not available, have
the vehicle inspected by an authorized
HYUNDAI dealer as soon as possible.
NOTICE
• If the engine is not turned OFF
immediately after the Engine
Oil Pressure Warning Light is
illuminated, severe damage could
occur.
• 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 has started, turn the
engine off immediately. In this
case, 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. Add
fuel as soon as possible.
NOTICE
Driving with the Low Fuel Level warning
light on or with the fuel level below "E"
can cause the engine to misfire and
damage the catalytic converter.
