NOTICE
To prevent damage to the air ventilation
seat: • Use the air ventilation seat ONLY
when the climate control system
is on. Using the air ventilation seat
for prolonged periods of time with
the climate control system off could
cause the air ventilation seat to malfunction.
• NEVER use a solvent such as paint
thinner, benzene, alcohol or gasoline
to clean the seats.
• Avoid spilling liquids on the surface
of the front seats and seatbacks;
this may cause the air vent holes
to become blocked and not work
properly.
• Do not place materials such as
plastic bags or newspapers under
the seats. They may block the air
intake causing the air vents to not
work properly.
• Do not change the seat covers. It may
damage the air ventilation seat.
• If the air vents do not operate, restart
the vehicle. If there is no change,
have the vehicle inspected by an
authorized HYUNDAI dealer.

Information
• The fuel tank capacity is given in
chapter 2.
• The fuel gauge is supplemented 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.
WARNING
Running out of fuel can expose vehicle
occupants to danger.
You must stop and obtain additional
fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the "E
(Empty)" level.
NOTICE
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire and damage
the catalytic converter. Outside temperature gauge
„„Type A,B
OTM048112
„„Type C
ODN8A049031C
This gauge indicates the current outside
air temperature by 1°C (1°F).
Temperature range: 40°C ~ 60°C (-40°F ~ 140°F )
Note that the temperature indicated
on the LCD display may not change
as quickly as the outside temperature
(there may be a slight delay before the
temperature changes.)
You can change the temperature unit
from °C to °F or °F to °C in the User
Settings mode in the cluster:
- Go to User Settings Mode → Other →
Temperature Unit.
For vehicles equipped with Automatic
Climate Control, you can also: - Press and hold the AUTO and OFF buttons on the climate control unit for 3 seconds
