Fuel filler door
Opening the fuel filler door
1. Turn the engine off.
2. Push the centre edge of the fuel
filler door when the driver’s door is
unlocked.3. Pull the fuel filler door (1) out to
fully open.
4. To remove the fuel tank cap (2),
turn it anticlockwise. You may hear
a hissing noise as the pressure
inside the tank equalises.
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.

Fuel gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given in
chapter 8.
• A low fuel level is also indicated 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.Avoid driving with an extremely
low fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
NOTICE
i
Never remove the radiator 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.
WARNING
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "E (Empty)"
level.

Low Tyre Pressure
Warning Light
(if equipped)
This warning light illuminates:
When 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 one or more of your tyres
are significantly underinflated (The
location of the underinflated tyres
are displayed on the LCD display).
For more details, refer to
“Tyre Pressure Monitoring
System (TPMS)” in chapter 6.
This warning light remains on after
blinking for approximately 60 sec-
onds or repeatedly blinks on and off
at approximately 3 second intervals:
When there is a malfunction with
the TPMS.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer as
soon as possible.
For more details, refer to
“Tyre Pressure Monitoring
System (TPMS)” in chapter 6.
Fuel Filter Warning
Light
(for diesel engine)
This warning light illuminates:
When water has accumulated
inside the fuel filter.
In this case, remove the water from
the fuel filter.
For more details, refer to "Fuel
Filter" in chapter 7.
When the Fuel Filter Warning
Light illuminates, engine power
(vehicle speed & idle speed) may
decrease.
If you keep driving with the warn-
ing light on, engine parts (injec-
tor, common rail, high pressure
fuel pump) may be damaged. If
this occurs, we recommend that
you have the vehicle inspected
by an authorised HYUNDAI deal-
er as soon as possible.
NOTICE
Safe Stopping
The TPMS cannot alert you to
severe and sudden tyre dam-
age caused by external factors.
If you notice any vehicle insta-
bility, immediately take your
foot off the accelerator pedal,
apply the brakes gradually with
light force, and slowly move to
a safe position off the road.
WARNING

Convenient features of your vehicle
Low Pressure (if equipped)
This warning message is displayed if
the tyre pressure is low. The corre-
sponding tyre on the vehicle will be
illuminated.
For more details, refer to "Tyre
Pressure Monitoring System (TPMS)"
in chapter 6.
Turn on FUSE SWITCH
This warning message is displayed if
the fuse switch located on the fuse
box under the steering wheel is OFF.
You should turn the fuse switch on.
For more details, refer to “Fuses”
in chapter 7.
Low washer fluid (if equipped)
This warning message is displayed
if the washer fluid level in the reser-
voir is nearly empty.
Have the washer fluid reservoir
refilled.
Low fuel
This warning message is displayed if
the fuel tank is almost out of fuel.
When this message is displayed, the
low fuel level warning light in the
cluster will come on.
It is recommended to look for the
nearest service station and refuel as
soon as possible.
Add fuel as soon as possible.
Engine has overheated
(if equipped)
This warning message is displayed
when the engine coolant tempera-
ture is above 120°C (248°F). This
means that the engine is overheated
and may be damaged.
If your vehicle is overheated, refer
to “Overheating” in chapter 6.

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
adversely affect vehicle handling and
braking.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Fuel, engine coolant and engine
oil
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.

What to do in an emergency

The displayed tyre pressure values
may differ from those measured
with a tyre pressure gauge.
You can change the tyre pressure
unit in the User Settings mode on
the instrument cluster.
- psi, kpa, bar (Refer to "User
Setting Mode" in chapter 3).Tyre pressure monitoring sys-
tem
Each tyre, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tyre inflation pressure label. (If
your vehicle has tyres of a different
size than the size indicated on the
vehicle placard or tyre inflation pres-
sure label, you should determine the
proper tyre inflation pressure for
those tyres.)As an added safety feature, your
vehicle has been equipped with a
tyre pressure monitoring system
(TPMS) that illuminates a low tyre
pressure telltale when one or more
of your tyres is significantly under-
inflated. Accordingly, when the low
tyre pressure telltale illuminates, you
should stop and check your tyres as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly under-inflated tyre causes
the tyre to overheat and can lead to
tyre failure. Under-inflation also
reduces fuel efficiency and tyre tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS is not a
substitute for proper tyre mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tyre pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tyre pressure
telltale. Over-inflation or under-inflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure that
may cause loss of vehicle con-
trol resulting in an accident.
