Petrol engine
Unleaded
For the optimal vehicle performance, we recommend you use unleaded petrol which
has an octane rating of RON (Research Octane Number) 95 / AKI (Anti Knock Index)
91 or higher. You may use unleaded petrol with an octane rating of RON 91-94 / AKI
87-90 but it may result in slight performance reduction of the vehicle. (Do not use
methanol blended fuels)
Your new vehicle is designed to obtain maximum performance with UNLEADED FUEL,
as well as minimise 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 a HYUNDAI authorised repairer for
details.)
WARNING

[Do not “top off” after the nozzle automatically shuts off when refuelling.

[Always check that the fuel cap is installed securely to prevent fuel spillage in the
event of an accident.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, we recommend
that the exhaust system be checked as soon as possible by a HYUNDAI authorised
repairer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at “Fresh” and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windscreen clear of snow, ice, leaves, or other obstructions.
If you must drive with the tailgate open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at “Fresh”, the air flow control at “Floor” or “Face”, and the
fan control set to high.

Driving your vehicle
Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P (Park)
position.
3DUNLQJ
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake, and
place the ignition switch in the LOCK/
OFF position. Take the Key with you
when exiting the vehicle.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator pedal for a long
period of time. The engine or exhaust
system may overheat and start a fire.
The exhaust gas and the exhaust
system are very hot. Keep away from
the exhaust system components.
Do not stop or park over flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a
fire.
Good driving practices

[Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.

[Never move the shift lever into P
(Park) when the vehicle is in motion.

[ Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).

[Do not move the shift lever to N
(Neutral) when driving. Doing so may
result in an accident because of a loss
of engine braking and the transmission
could be damaged.

[Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.

[Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.

[When driving in manual shift mode,
slow down before shifting to a lower
gear. Otherwise, the lower gear may
not be engaged if the engine rpms are
outside of the allowable range.

[Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.

[Exercise extreme caution when driving
on a slippery surface. Be especially
careful when braking, accelerating or
shifting gears. On a slippery surface,
an abrupt change in vehicle speed can
cause the drive wheels to lose traction
and may cause loss of vehicle control
resulting in an accident.

Trailer towing equipment
Towbars
OBC3060011
It's important to have the correct
towbar equipment. Crosswinds, large
trucks going by, and rough roads are a
few reasons why you’ll need the right
towbar. Here are some rules to follow:

[Do you have to make any holes in the
body of your vehicle when you install
a trailer towbar? If you do, then be
sure to seal the holes later when you
remove the towbar. If you don’t seal
them, carbon monoxide (CO) from
your exhaust can get into your vehicle,
as well as dirt and water.

[The bumpers on your vehicle are not
intended for towbars. Do not attach
rental towbars or other bumper-type
towbars to them. Use only a frame-
mounted towbar that does not attach
to the bumper.

[A HYUNDAI trailer towbar accessory
is available at a HYUNDAI authorised
repairer.
Safety chains
You should always attach chains
between your vehicle and your trailer.
Cross the safety chains under the
tongue of the trailer so that the tongue
will not drop to the road if it becomes
separated from the towbar. Instructions
about safety chains may be provided
by the towbar manufacturer or trailer
manufacturer. Follow the manufacturer’s
recommendation for attaching safety
chains. Always leave just enough slack
so you can turn with your trailer. And,
never allow safety chains to drag on the
ground.
Trailer brakes
If your trailer is equipped with a
braking system, make sure it conforms
your country’s regulations and that
it is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes loaded, then it needs its own
brakes and they must be adequate. Be
sure to read and follow the instructions
for the trailer brakes so you’ll be able
to install, adjust and maintain them
properly. Be sure not to tap into your
vehicle's brake system.
WARNING
Do not use a trailer with its own brakes
unless you are absolutely certain that
you have properly set up the brake
system. This is not a task for amateurs.
Use an experienced, competent trailer
shop for this work.
