Information
Using the system primarily in Fresh mode
and Recirculation mode only when needed
is recommended for best results.
Prolonged operation of the heater in
Recirculation mode and without the A/C
ON can cause fogging of the windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged period of
time may cause drowsiness to the
occupants in the cabin. This may lead
to loss of vehicle control which may
lead to an accident.
• Continued use of the climate control
system operation in Recirculation
mode with the A/C OFF may allow
humidity to increase inside the
cabin. This may cause condensation
to accumulate on the windshield and
obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle with
the windows up and either the
heater or the air conditioning ON for
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.

To charge a cellular phone
The wireless cellular phone charging
system charges only the Qi-enabled
cellular phones. Read the label on the
cellular phone accessory cover or visit
your cellular phone manufacturer’s
website to check whether your cellular
phone supports the Qi technology.
The wireless charging process starts
when you put a Qi-enabled cellular
phone on the wireless charging unit.

is still on the wireless charging unit after
the engine is turned OFF and the front
door is opened.
Information
For some manufacturers’ cellular phones,
the system may not warn you even though
the cellular phone is left on the wireless
charging unit. This is due to the particular
characteristic of the cellular phone and
not a malfunction of the wireless charging.
NOTICE
• The wireless cellular phone charging system may not support certain
cellular phones, which are not
verified for the Qi specification (
).
•

When placing y

our cellular phone
on the charging mat, position the
phone in the middle of the mat for
optimal charging performance. If
your cellular phone is off to the side,
the charging rate may be less and in
some cases the cellular phone may
experience higher heat conduction.

eless charging
may stop temporarily when the
Remote Key or Smart Key is used,
either when starting the vehicle or
locking/unlocking the doors, etc.

Floor Mat Anchor(s)
ALWAYS use the Floor Mat Anchors to
attach the front floor mats to the vehicle.
The anchors on the front floor carpet
keep the floor mats from sliding forward.
WARNING
Do not overlay additional mats or liners
over the floor mats. If using All Weather
mats, remove the carpeted floor mats
before installing them. Only use floor
mats designed to connect to the
anchors.
WARNING
The following must be observed when
installing ANY floor mat to the vehicle.
• Ensure to remove a protective
film attached on the carpet
before attaching a floor mat on
the front floor carpet. Otherwise,
the floor mat may move freely on
the protective film and it could
result in unintentional braking or
accelerating.
• Ensure that the floor mats are
securely attached to the vehicle’s
floor mat anchor(s) before driving
the vehicle.
• Do not use ANY floor mat that cannot
be firmly attached to the vehicle’s
floor mat anchors.
• Do not stack floor mats on top of one
another (e.g. all-weather rubber mat
on top of a carpeted floor mat). Only
a single floor mat should be installed
in each position.
IMPORTANT - Your vehicle was
manufactured with driver’s side floor
mat anchors that are designed to
securely hold the floor mat in place.
To avoid any interference with pedal
operation, HYUNDAI recommends that
the HYUNDAI floor mat designed for use
in your vehicle be installed.
