Maintenance
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes are
required.
Drive belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked
periodically for proper tension and
adjusted as necessary.
NOTICE
When you are inspecting the belt, place
the ignition switch in the LOCK/OFF or
ACC position.
Fuel filter
A clogged filter can limit the speed
at which the vehicle may be driven,
damage the emission system and cause
multiple issues such as hard starting.
If an excessive amount of foreign
matter accumulates in the fuel tank, the
filter may require replacement more
frequently.
After installing a new filter, run the
engine for several minutes, and check
for leaks at the connections.
We recommend that the fuel filter be
replaced by an authoized HYUNDAI
dealer.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend that the fuel lines, fuel
hoses and connections be replaced by
an authoized HYUNDAI dealer.
WARNING
Diesel Engine
Never manipulate or modify the
injection system while running the
diesel engine or within 30 seconds
after turning OFF the diesel engine. The
high-pressure pump, high-pressure
pipes, rail, and injectors are still subject
to high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out, it
may cause serious body injury. Any
people, who are implanted with the
artificial cardiac pacemaker, should
remain away from the ECU or the
wiring harness by at least 30 cm,
while running the diesel engine. The
high currents of the electronic engine
control system produce a considerable
amount of magnetic fields.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.

Checking the brake/clutch fluid
level
OBC3090016ROBC3090016R
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) 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 (Maximum) level. The
level will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings and/or
clutch disc (if equipped).
If the fluid level is excessively low, we
recommend that the system be checked
by an authorized HYUNDAI dealer.
Use only the specified brake/clutch fluid.
(Refer to “Recommended lubricants or
capacities” in chapter 2.)
Never mix different types of fluid.
WARNING
Loss of brake fluid
In the event the brake system
requires frequent additions of fluid,
we recommend that the system be
inspected by an authorized HYUNDAI
dealer.
i Information
Before removing the brake/clutch filter
cap, read the warning on the cap.
WARNING
Clean filler cap before removing. Use
only DOT 4 brake/clutch fluid from a
sealed container.
