3. Pull the fuel filler door (1) out tofully open.
4. To remove the fuel tank cap (2), turn it anticlockwise. You may hear
a hissing noise as the pressure
inside the tank equalizes.
5. Place the cap on the fuel filler door.
Information
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break
the ice and release the door. Do not
pry on the door. If necessary, spray
around the door with an approved de-
icer fluid (do not use radiator anti-
freeze) or move the vehicle to a warm
place and allow the ice to melt.
Closing the fuel filler door
1. To install the fuel tank cap, turn it clockwise until it “clicks” one time.
2. Close the fuel filler door until it is latched securely.
i
Petrol is highly flammable and
explosive. Failure to follow
these guidelines may result in
SERIOUS INJURY or DEATH:
Read and follow all warnings
posted at the gas station.
Before refuelling, note the
location of the Emergency
Petrol Shut-Off, if available, at
the gas station.
Before touching the fuel noz-
zle, you should eliminate the
potential build-up of static
electricity by touching a metal
part of the vehicle, a safe dis-
tance away from the fuel filler
neck, nozzle, or other gas
source, with your bare hand.

WARNING
OAE046025
(Continued)
Do not use mobile phones
whilst refuelling. Electric cur-
rent and/or electronic interfer-
ence from mobile phones can
potentially ignite fuel vapours
and cause a fire.
Do not get back into a vehicle
once you have begun refu-
elling. You can generate a
build-up of static electricity by
touching, rubbing or sliding
against any item or fabric capa-
ble of producing static electric-
ity. Static electricity discharge
can ignite fuel vapours causing
a fire. If you must re-enter the
vehicle, you should once again
eliminate potentially danger-
ous 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.(Continued)

Malfunction IndicatorLamp (MIL)
This warning light illuminates:
Once you turn the ignition switch or
the Engine Start/Stop button to the
ON position.
- It illuminates for approximately 3seconds 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
a HYUNDAI authorised repairer.
Driving with the Malfunction
Indicator Lamp (MIL) on may
cause damage to the emission
control system which could affect
drivability and/or fuel economy. If the Malfunction Indicator Lamp
(MIL) illuminates, potential catalyt-
ic converter damage is possible
which could result in loss of
engine power.
In this case, we recommend that
you have the vehicle inspected by
a HYUNDAI authorised repairer as
soon as possible.
Charging System
Warning Light
When this warning light illuminates
whilst running the engine, the battery
is not being charged. Immediately
turn OFF all electrical accessories.
Try not to use electrically operated
controls, such as the power windows.
Keep running the engine.
We recommend that you have the
vehicle inspected by a HYUNDAI
authorised repairer as soon as possi-
ble.
Engine Oil PressureWarning 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
location and stop your vehicle.
2. Turn the engine off and check the engine oil level (For more informa-
tion, refer to “Engine Oil” in chap-
ter 7) . If the level is low, add oil as
required.
If the warning light remains on
after adding oil or if oil is not avail-
able, we recommend that you
have the vehicle inspected by a
HYUNDAI authorised repairer as
soon as possible.

If the warning light stays on whilst the engine is running, it
indicates that there may be seri-
ous engine damage or malfunc-
tion. 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.

er.
Low Fuel LevelWarning Light
This warning light illuminates:
When the fuel tank is nearly empty.
Add fuel as soon as possible.
Driving with the Low Fuel Level
warning light on or with the fuel
level below "0" can cause the
engine to misfire and damage the
catalytic converter (if equipped).
Engine Coolant Temperature WarningLight
This warning light illuminates:
When the engine coolant temper-
ature is above 120°C (248°F). This
means that the engine is overheat-
ed and may be damaged.

Driving your vehicle
If you believe your brakes may be wet, apply them lightly whilst driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tyre tread
decreases, refer to "Tyre Tread" in
chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times whilst the vehicle is mov-
ing slowly.
Highway driving
Tyres
Adjust the tyre inflation, as specified.
Under-inflation may overheat or
damage the tyres.
Do not install worn-out or damaged
tyres, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Fuel, engine coolant and engineoil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

If you are considering to tow with
your vehicle, you should first your
country's legal requirements. As laws
vary the requirements for towing trail-
ers, cars, or other types of vehicles
or apparatus may differ. Ask a
HYUNDAI authorised repairer for fur-
ther details before towing.
Remember that trailering is different
than just driving your vehicle by itself.
Trailering means changes in han-
dling, durability, and fuel economy.
Successful, safe trailering requires
correct equipment, and it has to be
used properly. Damage to your vehi-
cle caused by improper trailer towing
is not covered by your vehicle manu-
facturer’s warranty.
This section contains many time-
tested, important trailering tips and
safety rules. Many of these are
important for your safety and that of
your passengers. Please read this
section carefully before you pull a
trailer.Information - For Europe
• The technically permissible maxi- mum load on the rear axle(s) may be
exceeded by not more than 15 %
and the technically permissible
maximum laden mass of the vehicle
may be exceeded by not more than
10% or 100 kg (220.4 lbs), whichev-
er value is lower. In this case, do not
exceed 100 km/h (62.1 mph) for
vehicle of category M1 or 80 km/h
(49.7 mph) for vehicle of category
N1.
• When a vehicle of category M1 is towing a trailer, the additional load
imposed at the trailer coupling
device may cause the tyre maximum
load ratings to be exceeded, but not
by more than 15%. In this case, do
not exceed 100 km/h (62.1 mph) and
increase the tyre inflation pressure
by at least 0.2 bar.i

Driving your vehicle
Take the following precautions:
If you don't use the correct
equipment and/or drive improp-
erly, you can lose control of the
vehicle when you are pulling a
trailer. For example, if the trailer
is too heavy, the braking per-
formance may be reduced. You
and your passengers could be
seriously or fatally injured. Pull
a trailer only if you have fol-
lowed all the steps in this sec-
tion.
Before towing, make sure the
total trailer weight, GCW
(Gross Combination Weight),
GVW (Gross Vehicle Weight),
GAW (Gross Axle Weight) and
trailer tongue load are all with-
in the limits.
