Maintenance
30 7
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 dirt
does not enter the air intake, or
damage 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 the
stoppers 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.

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- Recharging
battery
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.
