Maintenance

BATTERY

For best battery service

The electrolyte level should be between

LOWER (MIN) and UPPER (MAX).

When the electrolyte level is low, add

distilled (or de-mineralized) water.

(Never add sulfuric acids or other elec-

trolyte).

Be careful not to spill distilled (or de-

mineralized) water over the battery

surface or other adjacent components.

Also, do not overfill the battery cells.

If not, it may corrode the battery or

other components. Finally, securely

close the cell cap. However, we recom-

mend you to contact a HYUNDAI au-

thorised repairer for better battery

service.

• Keep the battery securely mounted.

• Keep the battery top clean and dry.

• Keep the terminals and connections

clean, tight, and coated with petro-

leum jelly or terminal grease.

WARNING

• Rinse any spilled electrolyte from the

battery immediately with a solution of

water and baking soda.

• If the vehicle is not going to be used

for an extended time, disconnect the

battery cables.

To prevent SERIOUS INJURY or

DEATH to you or bystanders, always

follow these precautions when work-

ing near or handling the battery:

Always read and follow

instructions carefully

when handling a battery.

Information

- For batteries marked with

UPPER and LOWER

Wear eye protection de-

signed to protect the eyes

from acid splashes.

Keep all flames, sparks,

or smoking materials

away from the battery.

Hydrogen is always pres-

ent in battery cells, is

highly combustible, and

may explode if ignited.

OHYK077011

If your vehicle is equipped with a bat-

tery marked with LOWER (MIN) and

UPPER (MAX) on the side, you should

check the electrolyte level.

• The battery may rupture or ex-

plode when you jump start with a

low or frozen battery.

Batteries contain sulfuric

acid which is highly cor-

rosive. Do not allow acid

to contact your eyes, skin

or clothing.

• Leaked battery electrolyte due to

repeated driving on sharp curves

(for example, on circuits) may

cause safety problem. Avoid re-

peated driving on sharp curves.

If acid gets into your eyes, flush your

eyes with clean water for at least 15

minutes and get immediate medical

attention. If acid gets on your skin,

thoroughly wash the area. If you feel

pain or a burning sensation, get

medical attention immediately.

NOTICE

Always follow these instructions

when handling your vehicle’s bat-

tery to prevent damage to your bat-

tery:

• When lifting a plastic-cased bat-

tery, excessive pressure on the

case may cause battery acid to

leak. Lift with a battery carrier or

with your hands on opposite cor-

ners.

• When you do not use the vehicle

for a long time in a low tempera-

ture area, disconnect the battery

and keep it indoors.

• Do not attempt to jump start your

vehicle if your battery is frozen.

• Always charge the battery fully to

prevent battery case damage in

low temperature areas.

• NEVER attempt to recharge the

battery when the vehicle’s battery

cables are connected to the bat-

tery.

• Prevent liquid from wetting the

battery terminals. The perfor-

mance of the battery may be de-

graded, and may cause injury. Be

cautious when loading liquid in the

boot.

• The electrical ignition system

works with high voltage. NEVER

touch these components with the

engine running or when the igni-

tion switch is in the ON position.

• Do not tilt the battery.

• If you connect unauthorised elec-

tronic devices to the battery, the

battery may be discharged. Never

use unauthorised devices.

• Do not allow the (+) and (-) jumper

cables to touch. It may cause

sparks.

When recharging the battery, ob-

serve the following precautions:

• Before performing maintenance or

recharging the battery, turn off all

accessories and stop the engine.

• Do not allow cigarettes, sparks, or

flame near the battery.

• Wear eye protection when check-

ing the battery during charging.

h The actual battery label in the vehicle

• Watch the battery during charging,

and stop or reduce the charging

rate if the battery cells begin gas-

sing (boiling) violently or if the

temperature of the electrolyte of

any cell exceeds 49°C (120°F).

ity (in min.)

• Disconnect the battery charger in

the following order.

5. CCA 560A : Cold-test current in am-

2. Unhook the negative clamp

from the negative battery termi-

nal.

Battery recharging

Your vehicle has a maintenance-free,

calcium-based battery.

• If the battery becomes discharged

over a short time (because, for ex-

ample, the headlights or interior lights

were left on whilst the vehicle was not

in use), recharge it by slow charging

(trickle) for 10 hours.

3. Unhook the positive clamp from

the positive battery terminal.

• If the battery gradually discharges

because of high electrical load whilst

the vehicle is being used, recharge it

at 20-30A for two hours.

By jump starting

NOTICE

After a jump start from a good battery,

drive the vehicle for at least 30 minutes

or operate at idle for at least 60 minutes

before it is shutoff. The vehicle may not

restart if you shut it off before the bat-

tery had a chance to adequately re-

charge. See “Jump Starting” in chapter

8 for more details on jump starting pro-

cedures.

AGM battery (if equipped)

• Absorbent Glass Mat (AGM) bat-

teries are maintenance-free and

we recommend that the AGM bat-

tery be serviced by a HYUNDAI au-

thorised repairer. For charging

your AGM battery, use only fully

automatic battery chargers that

are specially developed for AGM

batteries.

Information

• When replacing the AGM battery,

we recommend that you use parts

for replacement from a HYUNDAI

authorised repairer.

An inappropriately dis-

posed battery can be harm-

ful to the environment and

human health. Dispose of

the battery according to

your local law(s) or regula-

tion.

• 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.

Reset items

Items should be reset after the battery

has been discharged or the battery has

been disconnected.

• Auto up/down window

(See chapter 5)

• Trip computer (See chapter 4)

• Climate control system

(See chapter 5)
