BRAKE AND CLUTCH (IF EQUIPPED) FLUID
Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination. If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage. This is a nor-
mal condition associated 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/clutch
fluid. (Refer to “Recommended lubri-cants or capacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding
brake/clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If
brake/clutch fluid should come
in contact with your eyes, imme-
diately 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.
OBK079007
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's bodypaint, as paint damage willresult. Brake/clutch fluid, whichhas been exposed to open airfor an extended time shouldnever be used as its quality can-not be guaranteed. It should bedisposed of properly. Don't putin the wrong kind of fluid. A fewdrops of mineral-based oil, suchas engine oil, in your brake /clutch system can damagebrake / clutch 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 reservoir periodically. The
fluid should be between MAX and
MIN marks on the side of the gauge
at the normal temperature.
Before adding power steering fluid,
thoroughly clean the area around the
reservoir cap to prevent power steer-
ing 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 gauge. If the
fluid is cold, check that it is in the
"COLD" range.
In the event the power steering sys-
tem 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 lubri-cants or capacities" in section 8.)
Checking the power steering
hose
Check the connections for oil leaks,
damage and twists in the power
steering hose before driving.
CAUTION
To avoid damage to the power steering pump, do not operatethe vehicle for prolonged peri-ods with a low power steeringfluid level.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into thetank.
Too little fluid can result in increased steering effortand/or noise from the powersteering system.
(Continued)
(Continued) The use of the non-specified fluid could reduce the effective-ness of the power steering sys-tem and cause damage to it.
