Use only the bulbs of the specified
wattage.
The headlamp and tail lamp lens-
es could appear frosty if the vehi-
cle is washed after driving or the
vehicle is driven at night in wet
weather. This condition is caused
by temperature difference
between the lamp inside and out-
side and, it does not indicate a
problem with your vehicle.When moisture condenses in the
lamp, it will be removed after driv-
ing with the headlamp on. The
removable level may differ
depending on lamp size, lamp
position and environmental condi-
tion. However, if moisture is not
removed, we recommend that
your vehicle is inspected by an
authorised HYUNDAI dealer.
Information - Headlamp des-
iccant
(if equipped)
This vehicle is equipped with desic-
cant to reduce fogging inside the head-
lamp due to moisture.
The desiccant is consumable and its
performance may change based on the
used period or environment. If fog-
ging inside the headlamp due to mois-
ture continues for a long time, we rec-
ommend that you consult an autho-
rised HYUNDAI dealer.i
NOTICEBe sure to replace the burned-
out bulb with one of the same
wattage rating. Otherwise, it
may cause damage to the fuse
or electric wiring system.
CAUTION
If you don’t have necessary
tools, the correct bulbs and the
expertise, consult an autho-
rised HYUNDAI dealer. In many
cases, it is difficult to replace
vehicle light bulbs because
other parts of the vehicle must
be removed before you can get
to the bulb. This is especially
true if you have to remove the
headlamp assembly to get to
the bulb(s).
Removing/installing the head-
lamp assembly can result in
damage to the vehicle.
CAUTION
Working on the lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the Engine
Start/Stop button is turned to
the OFF position and turn off
the lights to avoid sudden
movement of the vehicle and
burning your fingers or receiv-
ing an electric shock.

Handle halogen bulbs with
care. Halogen bulbs contain
pressurised gas that will pro-
duce flying pieces of glass
that could cause injuries if
broken.
Wear eye protection when
changing a bulb. Allow the
bulb to cool down before han-
dling it.
