It will also be triggered automatically
when the vehicle is equipped with a TPS
system which does not function in the
event of a severe accident.
The 112-based eCall in-vehicle system
can also be triggered manually, if
needed. Instructions for manual
activation of the system: refer to this
section.
In the event of a critical system failure
that would disable the 112-based eCall
in-vehicle system, the following warning
will be given to the occupants of the
vehicle: refer to this section.
Information on data processing
Any processing of personal data
through the 112-based eCall in-vehicle
system shall comply with the personal
data protection rules provided for in
Directives 95/46/EC (1) and 2002/58/
EC (2) of the European Parliament and
of the Council, and in particular, shall
be based on the necessity to protect
the vital interests of the individuals in

Elements of the Pan-European
eCall system, installed in passenger
compartment:
(1) SOS button
(2) LED
SOS button: the driver/passenger makes
an emergency call to the single duty
dispatch service by pressing the button.
LED: the red and green LED illuminates
for 3 seconds when the ignition switch
is in the ON position. After that they will

Maintenance
You should exercise the utmost care
to prevent damage to your vehicle and
injury to yourself whenever performing
any maintenance or inspection
procedures.
We recommend you have your vehicle
maintained and repaired by a HYUNDAI
authorised repairer. A HYUNDAI
authorised repairer meets HYUNDAI’s
high service quality standards and
receives technical support from
HYUNDAI in order to provide you with a
high level of service satisfaction.
Owner’s responsibility
Maintenance service and record
retention are the owner’s responsibility.
You should retain documents that show
proper maintenance has been performed
on your vehicle in accordance with
the scheduled maintenance service
charts shown on the following pages.
You need this information to establish
your compliance with the servicing
and maintenance requirements of your
vehicle warranties.
Detailed warranty information is
provided in your Service Passport.
Repairs and adjustments required as
a result of improper maintenance or a
lack of required maintenance are not
covered.
Owner maintenance
precautions
Inadequate, incomplete or insufficient
servicing may result in operational
problems with your vehicle that could
lead to vehicle damage, an accident, or
personal injury. This chapter provides
instructions only for the maintenance
items that are easy to perform.
Your vehicle should not be modified
in any way. Such modifications may
adversely affect the performance, safety
or durability of your vehicle and may, in
addition, violate conditions of the limited
warranties covering the vehicle.
NOTICE
Improper owner maintenance during
the warranty period may affect
warranty coverage. For details, read
the separate Service Passport provided
with the vehicle. If you’re unsure
about any servicing or maintenance
procedure, we recommend that the
system be serviced by a HYUNDAI
authorised repairer.

Wheels are also marked with important
information that you need if you ever
have to replace one. The following
explains what the letters and numbers in
the wheel size designation mean.
Example wheel size designation:
6.0J X 15
6.0 - Rim width in inches.
J - Rim contour designation.
15 - Rim diameter in inches.

The chart below lists many of the
different speed ratings currently being
used for passenger vehicle tyres. The
speed rating is part of the tyre size
designation on the sidewall of the tyre.
This symbol corresponds to that tyre’s
designed maximum safe operating
speed.
Speed Rating
SymbolMaximum Speed
S112 mph (180 km/h)
T118 mph (190 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (300 km/h)

3. Checking tyre life (TIN : Tyre
Identification Number)
Any tyres that are over six years old,
based on the manufacturing date,
(including the spare tyre) should be
replaced by new ones. You can find
the manufacturing date on the tyre
sidewall (possibly on the inside of
the wheel), displaying the DOT Code.
The DOT Code is a series of numbers
on a tyre consisting of numbers and
English letters. The manufacturing date
is designated by the last four digits
(characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT shows a plant
code number, tyre size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1521 represents that the
tyre was produced in the 15th week of
2021.
4. Tyre ply composition and
material
The number of layers or plies of
rubber-coated fabric in the tyre. Tyre
manufacturers also must indicate the
materials in the tyre, which include steel,
nylon, polyester, and others. The letter
“R” means radial ply construction; the
letter “D“ means diagonal or bias ply
construction; and the letter “B” means
belted-bias ply construction.

5. Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tyre. Do not exceed the maximum
permissible inflation pressure. Refer to
the Tyre and Loading Information label
for recommended inflation pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can
be carried by the tyre. When replacing
the tyres on the vehicle, always use a
tyre that has the same load rating as the
factory installed tyre.
7. Uniform tyre quality grading
Quality grades can be found where
applicable on the tyre sidewall between
tread shoulder and maximum section
width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A
7UHDGZHDU
The tread wear grade is a comparative
rating based on the wear rate of the tyre
when tested under controlled conditions
on a specified government test course.
For example, a tyre graded 150 would
wear one-and-a-half times (1½) as well
on the government course as a tyre
graded 100. The relative performance of tyres
depends upon the actual conditions
of their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.
These grades are molded on the
sidewalls of passenger vehicle tyres. The
tyres available as standard or optional
equipment on your vehicle may vary
with respect to grade.
7UDFWLRQ$$$% &
The traction grades, from highest to
lowest, are AA, A, B and C. Those grades
represent the tyre’s ability to stop on wet
pavement as measured under controlled
conditions on specified government
test surfaces of asphalt and concrete. A
tyre marked C may have poor traction
performance.
WARNING
The traction grade assigned to this tyre
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
