Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
over a short time (because, for
example, the headlamps or interior
lights were left on whilst the vehicle
was not in use), recharge it by slow
charging (trickle) for 10 hours.
If the battery gradually discharges
because of high electrical load
whilst the vehicle is being used,
recharge it at 20-30A for two hours.

Maintenance
AGM battery (if equipped)
Absorbent Glass Matt (AGM)
batteries are maintenance-
free and we recommend that
the AGM battery be serviced
by an authorised HYUNDAI
dealer. For charging your
AGM battery, use only fully
automatic battery chargers
that are specially developed
for AGM batteries.
When replacing the AGM bat-
tery, we recommend that you
use parts for replacement
from an authorised HYUNDAI
dealer.
Do not open or remove the
cap on top of the battery. This
may cause leaks of internal
electrolyte that could result in
severe injury.
CAUTION
Always follow these instructions
when recharging your vehicle’s
battery to avoid the risk of SERI-
OUS INJURY or DEATH from
explosions or acid burns:
Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and stop the engine.
Keep all flames, sparks, or
smoking materials away from
the battery.
Always work outdoors or in an
area with plenty of ventilation.
Wear eye protection when
checking the battery during
charging.
The battery must be removed
from the vehicle and placed in
a well ventilated area.

WARNING (Continued)
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin boiling violently.
The negative battery cable
must be removed first and
installed last when the battery
is disconnected. Disconnect
the battery charger in the fol-
lowing 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.
Always use a genuine HYUNDAI
approved battery when you
replace the battery.

tery, drive the vehicle for 20-30 min-
utes before it is shutoff. The vehicle
may not restart if you shut it off
before the battery had a chance to
adequately recharge. See “Jump
Starting” in chapter 6 for more infor-
mation on jump starting procedures.
Information
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the bat-
tery according to your local
law(s) or regulation.

Tyre care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tyre
inflation pressures and stay within the
load limits and weight distribution rec-
ommended for your vehicle.
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side centre pillar. (Continued)Replace tyres that are worn,
show uneven wear, or are dam-
aged. Worn tyres can cause
loss of braking effectiveness,
steering control, or 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 rec-
ommended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tyre failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tyres monthly for
proper inflation as well as
wear and damage.
The recommended cold tyre
pressure for your vehicle can
be found in this manual and on
the tyre label located on the
driver’s side centre pillar.
Always use a tyre pressure
gauge to measure tyre pres-
sure. Tyres with too much or
too little pressure wear
unevenly causing poor han-
dling.
Check the pressure of the
spare every time you check
the pressure of the other tyres
on your vehicle.

Maintenance
Recommended cold tyre infla-
tion pressures
All tyre pressures (including the
spare) should be checked when the
tyres are cold. “Cold tyres” means
the vehicle has not been driven for at
least three hours or driven less than
1.6 km.
Warm tyres normally exceed recom-
mended cold tyre pressures by 28 to
41 kPa (4 to 6 psi). Do not release air
from warm tyres to adjust the pres-
sure or the tyres will be under-inflat-
ed. For recommended inflation pres-
sure, refer to “Tyre and Wheels” in
chapter 8.Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tyre wear.
Over-inflation or under-inflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tyre failures that can
result in the loss of vehicle con-
trol resulting in an accident.
This risk is much higher on hot
days and when driving for long
periods at high speeds.
WARNING
Under-inflation results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation is also
possible. Keep your tyre pres-
sures at the proper levels. If a
tyre frequently needs refilling,
we recommend it be checked
by an authorised HYUNDAI
dealer.
Over-inflation produces a
harsh ride, excessive wear at
the centre of the tyre tread,
and a greater possibility of
damage from road hazards.
CAUTION

Maintenance
Check tyre inflation pressure
Check your tyres, including the spare
tyre, once a month or more.
How to check
Use a good quality tyre pressure
gauge to check tyre pressure. You
can not tell if your tyres are properly
inflated simply by looking at them.
Radial tyres may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tyre
valve stem. Press the tyre gauge
firmly onto the valve to get a pres-
sure measurement. If the cold tyre
inflation pressure matches the rec-
ommended pressure on the tyre and
loading information label, no further
adjustment is necessary. If the pres-
sure is low, add air until you reach
the recommended pressure. Make
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.If you overfill the tyre, release air by
pushing on the metal stem in the
centre of the tyre valve. Recheck the
tyre pressure with the tyre gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
Tyre rotation
To equalise tread wear, HYUNDAI
recommends that the tyres be rotat-
ed every 10,000 km or sooner if
irregular wear develops.
During rotation, check the tyres for
correct balance.
When rotating tyres, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tyre pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of the tyre.
Replace the tyre if you find any of
these conditions. Replace the tyre if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tyre
pressures to specification and check
lug nut tightness (proper torque is
11~13 kgf·m).

7-50
Maintenance
Disc brake pads should be inspected
for wear whenever tyres are rotated.
Information
The outside and inside of an unsym-
metrical tyre is distinguishable. When
installing an unsymmetrical tyre, be
sure to install the side marked "out-
side" facing the outside. If the side
marked "inside" is installed on the
outside, it will have a negative effect
on vehicle performance.
Wheel alignment and tyre bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tyre
life and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tyre
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
Incorrect wheel weights can dam-
age your vehicle’s aluminium
wheels. Use only approved wheel
weights.

■ With a full-size spare tyre (if equipped)
■Without a spare tyre
Do not use the compact spare
tyre for tyre rotation.
Do not mix bias ply and radial
ply tyres under any circum-
stances. This may cause
unusual handling characteris-
tics that may cause loss of
vehicle control resulting in an
accident.

Maintenance
Tyre replacement
If the tyre is worn evenly, a tread
wear indicator will appear as a solid
band across the tread. This shows
there is less than 1.6 mm of tread left
on the tyre. Replace the tyre when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tyre.When replacing the tyres, recheck
and tighten the wheel nuts after
driving about 620 mile. If the steer-
ing wheel shakes or the vehicle
vibrates while driving, the tyre is
out of balance. Align the tyre bal-
ance. If the problem is not solved,
we recommend that you contact
an authorised HYUNDAI dealer.
