Checking the washer fluid level
OBC3090017
Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used if washer fluid
is not available.
However, use washer solvent with
antifreeze characteristics in cold
climates to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid:

[ 'RQRWXVHHQJLQHFRRODQWRU
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility when
sprayed on the windscreen and may
cause loss of vehicle control resulting
in an accident or damage to paint
and body trim.

[ 'RQRWDOORZVSDUNVRUIODPHVWR
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be
flammable.

[ 'RQRWGULQNZDVKHUIOXLGDQGDYRLG
contact with skin. Washer fluid is
poisonous to humans and animals.

[ .HHSZDVKHUIOXLGDZD\IURPFKLOGUHQ
and animals.
Checking the parking brake
OBC3060005
Check the stroke of the parking brake by
counting the number of “clicks’’ heard
whilst fully applying it from the released
position.
Also, the parking brake alone should
securely hold the vehicle on a fairly
steep grade. If the stroke is more or
less than specified, we recommend that
the system be inspected by a HYUNDAI
authorised repairer.
Stroke : 5~7 “clicks’’ at a force of 20 kg
(44 lbs, 196 N).

Maintenance
Filter inspection
The climate control air filter should be
replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it by
performing the following procedure,
and be careful to avoid damaging other
components.
Replace the filter according to the
Maintenance Schedule.
Filter replacement
OBC3050036R
1. Open the glove box.
OBC3090022R
2. Push in both sides of the glove box as
shown. This will ensure that the glove
box stopper pins will get released
from its holding location allowing the
glove box to hang.
OBC3N090013
3. Press and hold the lock on the left side
of the cover.
4. Pull out the cover.
5. Replace the climate control air filter.
6. Reassemble in the reverse order of
disassembly.
NOTICE
ODH073012
Install a new climate control air filter
in the correct direction with the
arrow symbol () facing downwards,
otherwise, it may be noisy and the
effectiveness of the filter may be
reduced.

WARNING
To reduce the risk of DEATH or SERIOUS
INJURY:

[Replace tyres that are worn, show
uneven wear, or are damaged. Worn
tyres can cause loss of braking
effectiveness, steering control, and
traction.

[Always replace tyres with the same
size as each tyre that was originally
supplied with this vehicle. Using
tyres and wheels other than the
recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or negatively
DIIHFW\RXUYHKLFOH
TV$QWL/RFN%UDNH
6\VWHP$%6UHVXOWLQJLQDVHULRXV
accident.

[When replacing tyres (or wheels), it
is recommended to replace the two
front or two rear tyres (or wheels)
as a pair. Replacing just one tyre
can seriously affect your vehicle’s
handling.

[Tyres degrade over time, even when
they are not being used. Regardless
of the remaining tread, HYUNDAI
recommends that tyres be replaced
after six (6) years of normal service.

[Heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process. Failure
to follow this warning may cause
sudden tyre failure, which could lead
to a loss of vehicle control resulting
in an accident.
Compact spare tyre replacement
(if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.
The replacement compact spare tyre
should be the same size and design
tyre as the one provided with your new
vehicle and should be mounted on the
same compact spare tyre wheel. The
compact spare tyre is not designed to
be mounted on a regular size wheel,
and the compact spare tyre wheel is not
designed for mounting a regular size
tyre.
WARNING
The original tyre should be repaired or
replaced as soon as possible to avoid
failure of the spare and loss of vehicle
control resulting in an accident. The
compact spare tyre is for emergency
use only. Do not operate your vehicle
over 50 mph (80 km/h) when using the
compact spare tyre.

Maintenance
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.
