Auxiliary battery (VAN/Truck)
The auxiliary battery is located in
engine room. (if equipped)
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a
solution of water and baking soda. Basically equipped battery is
maintenance free type. If your
vehicle is equipped with the bat-
tery marked with LOWER and
UPPER on the side, you can check
the electrolyte level. The elec-
trolyte level should be between
LOWER and UPPER. If the elec-
trolyte level is low, it needs to add
distilled (demineralized) water
(Never add sulfuric acid or other
electrolyte). When refill, be careful
not to splash the battery and adja-
cent components. And do not
overfill the battery cells. It can
cause corrosion on other parts.After then ensure that tighten the
cell caps. We recommend that you
contact an authorized HYUNDAI
dealer.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes dischargedin a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours. For the vehicle equipped with
ISG system (AGM battery), be
careful not to damage the bat-
tery sensor when the battery is
replaced or recharged.
1) When replacing the battery, it
should be same one (type, capacity and brand) that is
originally installed on your
vehicle. If a battery of a dif-
ferent type is replaced, bat-
tery sensor may recognize
the battery to be abnormal.
2) When installing the ground cable on the negative post of
battery, tighten the clamp
with specified torque of 4.0 ~
6.0 N.m (0.4 ~ 0.6 kgf.m, 3.0 ~
4.41 lb-ft). An excessive tight-
ening torque can damage the
PCB internal circuit.
3) When recharging the battery, ground the negative terminal
of the booster battery to the
vehicle body.CAUTION

Maintenance
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla- tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than1.6 km (1 mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in section8.
TTIIRR EESS AA NN DD WW HHEEEELLSS

Overinflation or underinfla-
tion can reduce tire life,
adversely affect vehicle han-
dling, and lead to sudden tire
failure. You must always main-tain recommended tire pres-sures.
Warm tires normally exceed recommended cold tire pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air fromwarm tires to adjust the pres-sure or the tires will be under-inflated.
Tire underinflation
If the tire pressure drops
repeatedly, the wheel, valve or
tire may be damaged. Underinflation results in reducing fitness of tire and
wheel, excessive wear, poorhandling and reduced fuel
economy. (Continued)
(Continued)
And it can lead to deformation or abnormal wear of wheel,
severe heat build-up, causing
blowouts, tread separationand other tire failures that can
result in the loss of vehicle
control leading to severe
injury or death. This risk is
much higher on hot days and
when driving for long periodsat high speeds.
If the problem is not solved (a
tire frequently needs refilling),we recommend that the sys-
tem be checked by an author-
ized HYUNDAI dealer.
Tire overinflation
Tires with excessively high
pressure can burst because
they are damaged more easily
by road debris, potholes etc.
In addition, they also produce
a harsh ride, excessive wearat the center of the tire tread,and a greater possibility of
damage from road hazards.
WARNING

Maintenance
Checking tire inflation pres- sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gage to check tire
pressure. You can not tell if your tires
are properly inflated simply by look-
ing at them. Radial tires may look
properly inflated even when they're
underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven nomore than 1.6 km (1 mile).
Tire pressure
Always observe the following:
Check tire pressure when the
tires are cold. (After vehicle
has been parked for at least
three hours or hasn't beendriven more than 1.6 km (1
mile) since startup.)
Check the pressure of your
spare tire each time you checkthe pressure of other tires.
Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
Worn, old tires can cause
accidents. If your tread is
badly worn, or if your tires
have been damaged, replacethem.
CAUTION
Tire inflation Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.
WARNING
Warm tires normally exceed recommended cold tire pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air fromwarm tires to adjust the pres-sure or the tires will be under-inflated.
Be sure to reinstall the tire
inflation valve caps. 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.
CAUTION

7-44
Maintenance
Remove the valve cap from the tire
valve stem. Press the tire gage firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflationpressure matches the recommendedpressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-ommended amount.
If you overfill the tire, release air by pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gage. Be
sure to put the valve caps back on
the valve stems. They help prevent
leaks by keeping out dirt and mois-
ture.Tire rotation
To equalize tread wear, it is recom- mended that the tires be rotated
every 12,000 km (7,500 miles) or
sooner if irregular wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire 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 tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness.
Refer to “Tire and wheels” in section 8.
Inspect your tires frequently
for proper inflation as well as
wear and damage. Always use
a tire pressure gauge.
Tires with too much or too lit-
tle pressure wear unevenly
causing poor handling, loss of
vehicle control, and suddentire failure leading to acci-
dents, injuries, and even
death. The recommended cold
tire pressure for your vehicle
can be found in this manualand on the tire label locatedon the driver's side center pil-
lar.
Worn tires can cause acci-
dents. Replace tires that are
worn, show uneven wear, or
are damaged.
Remember to check the pres-
sure of your spare tire.
HYUNDAI recommends that
you check the spare every
time you check the pressure
of the other tires on your vehi-
cle.
WARNING

Maintenance
Disc brake pads should be inspectedfor wear whenever tires are rotated.
Rotate radial tires that have an
asymmetric tread pattern only
from front to rear and not fromright to left.
Wheel alignment and tire bal- ance
The wheels on your vehicle were aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may needto be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.NOTICE
Do not use the compact spare
tire for tire rotation.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause
unusual handling characteris-tics that could result in death,
severe injury, or property
damage.
WARNING
Improper wheel weights can
damage your vehicle's alu-
minum wheels. Use only
approved wheel weights.

Maintenance
Tire replacement
If the tire is worn evenly, a tread wear indicator will appear as a solid band
across the tread. This shows there isless than 1.6 mm (1/16 in.) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.When replacing the tires,
recheck and tighten the wheel
nuts after driving about 1,000
km (620miles). If the steering
wheel shakes or the vehicle
vibrates while driving, the tire is
out of balance. Align the tire
balance. If the problem is not
solved, we recommend that you
contact an authorized HYUNDAI
dealer.
CAUTION
Replacing tires
Driving on worn-out tires is
very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-tion.
Your vehicle is equipped with
tires designed to provide for
safe ride and handling capa-
bility. Do not use a size andtype of tire and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tires, be sure to equip all
four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capacity.

Maintenance
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim widthand offset.
Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire maintenance
In addition to proper inflation, correct wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer or otherrepair shops that use qualified tech-
nicians check the wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removedfrom the wheel.
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.
WARNING
(Continued)
The use of any other tire size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tire clearance, snow tire
clearance, and speedometer
reliability.
It is best to replace all four
tires at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tires as a pair.Replacing just one tire can
seriously affect your vehicle’shandling.
The ABS works by comparing
the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESP (Electronic Stability
Program) (if equipped) to
work irregularly.
