Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele-ment more often than the usual recom-mended intervals. (Refer to“Maintenance under severe usage condi-tions” in this section.)
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 per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
Filter replacement
1. Open the glove box and remove the support strap (1).
CAUTION
Do not drive with the air cleaner removed; this will result in exces-sive engine wear.
When removing the air cleaner fil- ter, be careful that dust or dirtdoes not enter the air intake, ordamage may result.
Use a HYUNDAI genuine part. Use of non-genuine parts could dam-age the air flow sensor.

2. With the glove box open, remove thestoppers by turning them counter-
clockwise on both sides. 3. Remove the climate control air filter
cover while pressing the lock on the
right of the cover. 4. Replace the climate control air filter.
5. Reassemble in the reverse order of
disassembly.
✽ ✽NOTICE
When replacing the climate control air
filter install it properly. Otherwise, the
system may produce noise and the effec-
tiveness of the filter may be reduced.

Reset items
Items should be reset after the battery
has been discharged or the battery has
been disconnected.

Audio (See section 4)WARNING
Before performing maintenance or recharging the battery, turn off
all accessories and stop the
engine.
The negative battery cable must be removed first and installed
last when the battery is discon-
nected.
Operation related to the battery should be done in an authorized
HYUNDAI dealer.
WARNING- Rechargingbattery
When recharging the battery,
observe the following precautions:
The battery must be removed
from the vehicle and placed in an
area with good ventilation.
Do not allow cigarettes, sparks, or flame near the battery.
Watch the battery during charg- ing, and stop or reduce the charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 120°F (49°C).
Wear eye protection when check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.

Tire speed ratings
The chart below lists many of the dif-
ferent speed ratings currently being
used for passenger car tires. The
speed rating is part of the tire size
designation on the sidewall of the
tire. This symbol corresponds to that
tire's designed maximum safe oper-
ating speed.
3. Checking tire life (TIN : Tire
Identification Number)
Any tires that are over 6 years old,
based on the manufacturing date,
(including the spare tire) should be
replaced by new ones. You can find
the manufacturing date on the tire
sidewall (possibly on the inside of the
wheel), displaying the DOT Code.
The DOT Code is a series of num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 1611 represents
that the tire was produced in the 16th
week of 2011.
S 112 mph (180 km/h)
T 118 mph (190 km/h)
H 130 mph (210 km/h) V 149 mph (240 km/h)Z Above 149 mph (240 km/h)

WARNING - Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates or
frequent high loading condi-
tions can accelerate the aging
process. Failure to follow this
warning can result in sudden
tire failure, which could lead to
a loss of control and an acci-
dent involving serious injury or
death.

4. Tire ply composition and material
The number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflationpressure
This number is the greatest amount of
air pressure that should be put in the
tire. Do not exceed the maximum per-
missible inflation pressure. Refer to
the Tire 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 tire. When replacing
the tires on the vehicle, always use a
tire that has the same load rating as
the factory installed tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and maxi-
mum section width.
For example: TREAD wear 200
TRACTION AA
TEMPERATURE A
Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tire graded 100.
The relative performance of tires
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
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on your vehicle
may vary with respect to grade.
Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteristics.
