Battery recharging by battery
charger
Your vehicle has a maintenance-free,
calcium-based battery.
When the battery is discharged ina short period of time (possibly
because the headlamps or interior
lights remain on, while the vehicle
is not in use), slowly recharge it
(trickle) for 10 hours.
When the battery is gradually dis- charged due to high electric load,
while the vehicle is in use,
recharge it at 20-30A for 2 hours.
Battery recharging by vehicle
After jump-starting from a good bat-
tery, run the engine for 20-30 min-
utes in either the idle or driving
modes, before turning off the engine.
Your vehicle may not restart, when
the engine is shortly turned off with-
out having an adequate recharging
time.
- Recharging battery
When recharging the battery,
follow the below precautions:
The battery must be removed from the vehicle and placed in
a well-ventilated area.

Tire care
For the better maintenance, safety,
and fuel economy, you must always
maintain the recommended tire infla-
tion pressures, and follow the load
limits and weight distribution recom-
mendation.
Recommended cold tire infla-
tion pressures
The tire pressure (including the
spare) should be measured, when it
is cold. A “cold tire” means the vehi-
cle does not drive for the last 3 hours
or is driven shorter than 1 mile (1.6
km).
The recommended pressure must be
maintained for the best driving, han-
dling, and the minimum tire wear-out.
For the information about the recom-
mended inflation pressure, refer to
“Tire and wheels” in the chapter 8.
All specifications (sizes and pres-
sures) are specified on the label
attached to the central pillar of the
driver's door.

Maintenance07
The pressure of a warm tire isnormally higher than the one of
a cold tire by 4 to 6 psi (28 to 41
kPa). Do not release air from a
warm tire to adjust the pressure.
Otherwise, the tire will be under-
inflated.
(Continued)(Continued)
Make sure to close the tire infla-
tion valve cap. When the valve is
opened, dirt or moisture may get
into the valve core and cause air
leakage. When a valve cap is
lost, immediately buy a new one,
and close the valve.
- Tire pressure
Always observe the following:
Measure the tire pressure when it is cold. (When the vehicle
does not drive for the last 3
hours, or when it drives shorter
than 1 mile (1.6 km), after start-
ing up.)
Check the pressure of a spare tire whenever checking the pres-
sures of other tires.
Never overload your vehicle. Be careful not to overload on the
luggage rack, when your vehicle
is equipped with one.
Worn-out, old tires may cause an accident. When your tread is
badly worn out, or when tires are
damaged, replace them.
NOTICE
NOTICE
- Underinflated tire
Severe under-inflation of tire
may cause severe build-up of
heat, causing blowouts, tread
separation and other failures.
This may result in the loss of
vehicle control, leading to a
severe injury or death. This risk
may increase when the weather
is hot, or when the vehicle
drives for a long period of time
at a high speed.
WARNING
- Tire Inflation
Over-inflation or under-inflation
may reduce tire life, adversely
affect vehicle handling, and
lead to a sudden tire failure.
This may result in a loss of vehi-
cle control and a potential
injury.
WARNING
Under-inflation also mayresult in excessive tire wear-
put, poor handling and inferi-
or fuel economy. Also, wheel
deformation may be resulted.
Maintain your tire pressure at
the recommended level. When
your tire frequently needs to
be inflated, have it checked by
an authorized EQUUS dealer.
Over-inflation may cause harsh driving, excessive tire
wear-out, especially for the
central tread of a tire, and
more possibilities of damage
from road hazards.
CAUTION

7-44
Maintenance
Checking tire inflation pres-
sure
Check your tires at least once a
month.
Also, check the spare tire pressure.
How to check
Use a good-quality gauge to check
the tire pressure. You cannot proper-
ly measure the tire inflation only with
your eyes. A radial tire may look
properly inflated, even when it is
underinflated.
Check the tire inflation pressure,
when it is cold. - A "cold" means
your vehicle does not drive for the
last 3 hours, or drives shorter than 1
mile (1.6 km).
Open the tire valve cap. Press the
tire gauge firmly onto the valve to
measure the pressure. When the
cold tire is inflated as recommended,
as specified on the tire and loading
information labels, further adjust-
ment is not needed. When a tire is
underinflated, inflate it to the recom-
mended pressure.
When overinflating the tire, release
air by pressing the metal stem on the
tire valve. Re-measure the tire pres-
sure with the gauge. Make sure to
close the valve caps over the valve
stems. This prevents air leakage and
keeps out dirt and moisture. Frequently check your tires,
especially inflation pressure,
abrasion and damage. Always
use a tire pressure gauge.
Overinflated or underinflated tires may unevenly wear out,
causing poor handling, a loss
of vehicle control, and a sud-
den tire failure. This may lead
to an accident, injury, and
even death. The cold tire pres-
sure recommendation of your
vehicle is specified in this
manual and on the tire label,
which is located on the center
pillar on the driver's side.
Tire abrasion may cause an accident. Replace the worn-
out or damaged tires.
Remember to check the spare tire pressure. It is recom-
mended to check the spare
whenever checking the pres-
sures of other tires.
WARNING

7-45
Maintenance07
Tire rotation
To balance worn-out levels of the tire
tread, rotating the tire positions is
required every 7,500 miles (12,000
km), or sooner, when the irregular
abrasion is detected. While rotating
the positions, correctly balance the
tire positions.
When rotating tires, check for any
uneven abrasion and damage.
Abnormal tire abrasion is usually
caused by improper tire pressure,
tilted wheel alignment, unbalanced
wheels, severe braking or hard cor-
nering. Check for any bump or
bulging from the tire side walls. When
finding one of those, replace you tire.
Replace the tire, when a tire cord
fabric is visible. After rotation, make
sure to properly inflate the tires to the
recommended pressure, as speci-
fied, and check the lug-nut tightness.
Disc brake pads should be inspectedfor any abrasion, whenever rotatingtires.
Information
The front tire size is different from the
rear tire size. So when you rotate tires,
check sizes of the tires and wheels.
Wheel alignment and tire bal-
ance
The wheels are finely aligned and
balanced at the manufacturing facto-
ry in order to ensure the longest tire
life and the best driving performance.
In most cases, you do not need to
realign the wheels. However, when
detecting unusual tire abrasion or
vehicle leaning to one side, the
realignment may be needed. When
your vehicle vibrates on an even sur-
face, while driving, your wheels may
need to be rebalanced.
Improperly overweighted wheel
may damage your vehicle's alu-
minum wheels. Carry only the
appropriate wheel weights.
NOTICE
i
OBK079038
Without a spare tire
Do not use the compact spare
tire for tire rotation.
Never mix bias-ply tires and radial-ply tires under any cir-
cumstances. This may cause
abnormal handling, possibly
resulting in a death, severe
injury, or property damage.
WARNING

7-46
Maintenance
Tire replacement
When a tire unevenly wears out, a
tread wear indicator, in a pattern of a
solid band, appears over the tread.
This indicates that there is less than
1/16 inch (1.6 mm) of tread left.
When finding it, replace the tire.
Do not delay the tire replacement,
until all the indicators appear over
the entire tire tread.
OEN076053
Tread wear indicator
- Replacing tires
To reduce the risk of a serious
or fatal injury, caused by a tire
failure or a loss of vehicle con-
trol, follow the below warnings:
Replace tires, which areseverely worn out, unevenly
wear out, or damaged. Worn-
out tires may degrade the
braking effects, steering con-
trol, and traction.
Do not drive your vehicle with overinflated or underinflated
tires. This may cause uneven
abrasion or a tire failure.
(Continued)
(Continued)
When replacing tires of yourvehicle, never mix radial-ply
tires and bias-ply tires. You
must replace all the tires
(including the spare) when
changing from radial-ply tires
to bias-ply tires.
Tires and wheels in the differ- ent sizes may cause abnormal
handling and poor vehicle
control, resulting in a serious
accident.
Wheels, which do not satisfy the HYUNDAI’s specifications,
may be unfit and result in a
vehicle damage, abnormal
handling and poor vehicle
control.
The ABS operates upon com- paring the wheel speeds. A
tire size determines a wheel
speed. When replacing tires,
all the tires must be in the
same size as the original
ones. Installing tires in a dif-
ferent size may cause irregu-
lar operation of the ABS (Anti-
lock Brake System) and ESC
(Electronic Stability Control).
