WARNING
Removing radiator
cap
Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.

Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
deonized water or soft water. Bring the
level to F (MAX), but do not overfill. If fre-
quent coolant refill is required, see an
authorized HYUNDAI dealer for a cooling
system inspection.
OXM079006
(Continued)
Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system.
When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning coun-
terclockwise to remove it.
Even if the engine is not operat- ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.WARNING
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use extreme
caution when working near the
blades of the cooling fan so that
you are not injured by a rotating fan
blades. As the engine coolant tem-
perature decreases, the electric
motor will automatically shut off.
This is a normal condition.

BRAKE FLUID
G080100AXM
Checking the brake fluid level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir. Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings.
If the fluid level is excessively low, have
the brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake fluid. (Refer
to “Recommended lubricants and capac-ities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
WARNING - Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
CAUTION
Do not allow brake fluid to contactthe vehicle's body paint, as paint damage will result. Brake fluid,which has been exposed to open air for an extended time should neverbe used as its quality cannot beguaranteed. It should be disposed of properly. Don't put in the wrongkind of fluid. A few drops of miner-al-based oil, such as engine oil, in your brake system can damagebrake system parts.

POWER STEERING FLUID
Checking the power steering fluid
level
With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the reservoir at the normal tem-
perature.
Before adding power steering fluid, thor-
oughly clean the area around the reser-
voir cap to prevent power steering fluid
contamination.
If the level is low, add fluid to the MAX
level.
✽ ✽NOTICE
Check that the fluid level is in the
"HOT" range on the reservoir. If the
fluid is cold, check that it is in the
"COLD" range.
In the event the power steering system
requires frequent addition of fluid, the
vehicle should be inspected by an
authorized HYUNDAI dealer.
Use only the specified power steering
fluid. (Refer to "Recommended lubricants or capacities" in section 8.)
Checking the power steering
hose
Check the connections for oil leaks, dam-
age and twists in the power steering
hose before driving.
CAUTION
To avoid damage to the power steering pump, do not operate thevehicle for prolonged periodswith a low power steering fluid level.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the tank.
Too little fluid can result in increased steering effort and/ornoise from the power steering system.
The use of the non-specified fluid could reduce the effectiveness ofthe power steering system andcause damage to it.
