Safety system of your vehicle
Seat Belt Anchor Pre-tensioner
The purpose of the Seat Belt Anchor
Pre-tensioner is to help the lap belt fit
tightly against the occupant's lower
body in certain frontal collisions. The
Seat Belt Anchor Pre-tensioner may
be activated in crashes where the
frontal collision is severe enough.Do not touch the pre-tensioner
seat belt assemblies for several
minutes after they have been
activated. When the pre-ten-
sioner seat belt mechanism
deploys during a collision, the
pre-tensioners become hot and
can burn you.
WARNING
Always wear your seat belt and
sit properly in your seat.
Do not use the seat belt if it is
loose or twisted. A loose or
twisted seat belt will not pro-
tect you properly in an acci-
dent.
Do not place anything near the
buckle. This may adversely
affect the buckle and cause it
to function improperly.
Always replace your pre-ten-
sioners after activation or an
accident.
NEVER inspect, service, repair
or replace the pre-tensioners
yourself. This must be done by
an authorized HYUNDAI dealer.
Do not hit the seat belt assem-
blies.

System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or
rough roads, more frequent air condi-
tioner filter inspections and changes
are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer.

Vehicles equipped with

Because the refriger-
ant is mildly inflam-
mable at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and
certified technicians.
It is important that the
correct type and amount of oil
and refrigerant is used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.

Introduction
With the Tire Mobility Kit you stay
mobile even after experiencing a tire
puncture.
The system of compressor and seal-
ing compound effectively and com-
fortably seals most punctures in a
passenger car tire caused by nails
or similar objects and reinflates the
tire.
After you ensured that the tire is
properly sealed you can drive cau-
tiously on the tire (distance up to 200
km (120 miles)) at a max. speed of
80 km/h (50 mph) in order to reach a
service station or tire dealer to have
the tire replaced.
It is possible that some tires, espe-
cially with larger punctures or dam-
age to the sidewall, cannot be sealed
completely.
Air pressure loss in the tire may
adversely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving
maneuvers, especially if the vehicle
is heavily loaded or if a trailer is in
use.The Tire Mobility Kit is not designed
or intended as a permanent tire
repair method and is to be used for
one tire only. This instruction shows
you step by step how to temporarily
seal the puncture simply and reliably.
Read the section "Notes on the safe
use of the Tire Mobility Kit".
What to do in an emergency
Do not use the Tire Mobility Kit
to repair punctures in the tire
walls. This can result in an acci-
dent due to tire failure.
WARNING
Have your tire repaired as soon
as possible. The tire may loose
air pressure at any time after
inflating with the Tire Mobility Kit.
WARNING
When two or more tires are flat,
do not use the tire mobility kit
because the supported one
sealant of Tire Mobility Kit is
only used for one flat tire.
CAUTION
Do not use the TMK if a tire is
severely damaged by driving run
flat or with insufficient air pres-
sure.
Only punctured areas located
within the tread region of the tire
can be sealed using the TMK.
