roads for a long period, it should beinspected more frequently and replaced
earlier. When you, the owner, replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents. Replace the filter according to the main-
tenance schedule.
Filter replacement

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 authorised
HYUNDAI dealer.
CAUTION
Keep the battery away from water
or any liquid.
For your safety, use the authentic- ity by approved authorisedHYUNDAI dealer, when youreplace the battery.
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 49°C (120°F).
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.

4. Tyre ply composition and material
The number of layers or plies of rub-
ber-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 con-
struction; the letter "D" means diago-
nal or bias ply construction; and theletter "B" means belted-bias ply con-
struction.
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 maxi-
mum section width.
For example:
TREADWEAR 200
TRACTION AA
TEMPERATURE A Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate ofthe tyre when tested under controlled
conditions on a specified govern-
ment test course. For example, a tyre
graded 150 would wear one-and-a-
half times (1½) as well on the gov-
ernment course as a tyre graded100.
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
side-walls of passenger vehicle
tyres. The tyres available as standard
or optional equipment on your vehi-
cle may vary with respect to grade.
