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.

Use of MTBE
HYUNDAI recommends avoiding fuels containing MTBE (Methyl Tertiary Butyl Ether)
over 15.0% vol. (Oxygen Content 2.7% weight) in your vehicle.
Fuel containing MTBE over 15.0% vol. (Oxygen Content 2.7% weight) may reduce
vehicle performance and produce vapour lock or hard starting.
CAUTION
Your New Vehicle Limited Warranty may not cover damage to the fuel system and
any performance problems that are caused by the use of fuels containing methanol
or fuels containing MTBE (Methyl Tertiary Butyl Ether) over 15.0% vol. (Oxygen
Content 2.7% weight.)
Do not use methanol
Fuels containing methanol (wood alcohol) should not be used in your vehicle. This
type of fuel can reduce vehicle performance and damage components of the fuel
system, engine control system and emission control system.
Fuel Additives
HYUNDAI recommends that you use unleaded petrol which has an octane rating of
RON (Research Octane Number) 95 / AKI (Anti Knock Index) 91 or higher (for Europe)
or Octane Rating of RON (Research Octane Number) 91 / AKI (Anti-Knock Index) 87 or
higher (except Europe).
For customers who do not use good quality petrols including fuel additives
regularly, and have problems starting or the engine does not run smoothly, one
bottle of additive added to the fuel tank according to the maintenance schedule is
recommended.
Additives are available from your HYUNDAI authorised repairer along with information
on how to use them. Do not mix other additives.
Operation in foreign countries

Engine Coolant Temperature Gauge
„3.5-Inch
OBC3040007/OBC3040008
„10.25-Inch
This gauge indicates the temperature
of the engine coolant when the ignition
switch is in the ON position.
NOTICE
If the gauge pointer moves beyond the
normal range area toward the “130”
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your vehicle
overheats, refer to “If the Engine
Overheats” in chapter 8.
WARNING
Never remove the radiator cap or
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could cause severe burns. Wait
until the engine is cool before adding
coolant to the reservoir.
Fuel Gauge

available, at the gas station.
[ Before touching the fuel nozzle, you
should eliminate the potential build-
up of static electricity by touching
a metal part of the vehicle, a safe
distance away from the fuel filler
neck, nozzle, or other gas source,
with your bare hand.
[ Do not use mobile phones whilst
refuelling. Electric current and/or
electronic interference from mobile
phones can potentially ignite fuel
vapours and cause a fire.

[ Do not get back into a vehicle
once you have begun refuelling.
You can generate a build-up of
static electricity by touching,
rubbing or sliding against any item
or fabric capable of producing
static electricity. Static electricity
discharge can ignite fuel vapours
causing a fire. If you must re-enter
the vehicle, you should once again
eliminate potentially dangerous
static electricity discharge by
touching a metal part of the vehicle,
away from the fuel filler neck, nozzle
or other petrol source, with your bare
hand.
[ When refuelling, always move the
shift lever to the N (Neutral, for

[ When using an approved portable
fuel container, be sure to place
the container on the ground prior
to refuelling. Static electricity
discharge from the container can
ignite fuel vapours causing a fire.
Once refuelling 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 petrol.[ Do not use matches or a lighter and
do not smoke or leave a lit cigarette
in your vehicle whilst at a gas station,
especially during refuelling.
[ Do not over-fill or top-off your
vehicle tank, which can cause petrol
spillage.
[ If a fire breaks out during refuelling,
leave the vicinity of the vehicle, and
immediately contact the manager
of the gas station and then contact

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

Two labels on your driver’s door sill show
how much weight your vehicle was
designed to carry: the Tyre and Loading
Information Label and the Certification
Label.
Before loading your vehicle, familiarize
yourself with the following terms for
determining your vehicle’s weight
ratings, from the vehicle’s specifications
and the Certification Label:
Base Kerb Weight
This is the weight of the vehicle
including a full tank of fuel and all
standard equipment. It does not
include passengers, cargo, or optional
equipment.
Vehicle Kerb Weight
This is the weight of your new vehicle
when you picked it up from your dealer
plus any aftermarket equipment.
Cargo Weight
This figure includes all weight added to
the Base Kerb Weight, including cargo
and optional equipment.
GAW (Gross Axle Weight)
This is the total weight placed on each
axle (front and rear) - including vehicle
kerb weight and all payload.
GAWR (Gross Axle Weight Rating)
This is the maximum allowable weight
that can be carried by a single axle (front
or rear). These numbers are shown on
the Certification Label. The total load on
each axle must never exceed its GAWR.GVW (Gross Vehicle Weight)
This is the Base Kerb Weight plus actual
Cargo Weight plus passengers.
GVWR (Gross Vehicle Weight Rating)
This is the maximum allowable weight
of the fully loaded vehicle (including
all options, equipment, passengers
and cargo). The GVWR is shown on
the Certification Label located on the
driver’s door sill.
Overloading
WARNING
The Gross Axle Weight Rating (GAWR)
and the Gross Vehicle Weight Rating
(GVWR) for your vehicle are on the
Certification Label attached to the
driver’s (or front passenger’s) door.
Exceeding these ratings can cause an
accident or vehicle damage. You can
calculate the weight of your load by
weighing the items (and people) before
putting them in the vehicle. Be careful
not to overload your vehicle.
