2023 HYUNDAI TUCSON oil change

Maintenance
9-14
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
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.
Information
When you are inspecting the belt, turn the
engine off.
Fuel lines, fuel hoses and
connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend an authorized HYUNDAI
dealer replace any damaged or leaking
parts immediately.
Fuel filter
The fuel filter is considered to be
maintenance free but periodic inspection
is recommended for this maintenance
depends on fuel quality. If there are
some important matters like fuel flow
restriction, surging, loss of power, hard
starting problem etc., replace the fuel
filter immediately. We recommend that
you consult an authorized HYUNDAI
dealer for details.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Your
HYUNDAI dealer will help to determine if
replacement is needed.
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage.
Hard and brittle rubber, cracking,
tears, cuts, abrasions, and excessive
swelling indicate deterioration. Particular
attention should be paid to examine
those hose surfaces nearest to high heat
sources, such as the exhaust manifold.
Inspect the hose routing to ensure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat
damage or mechanical wear. Inspect
all hose connections, such as clamps
and couplings, to make sure they are
secure, and that no leaks are present.
Hoses should be replaced immediately if
there is any evidence of deterioration or
damage.

Make sure to install new spark plugs of
the correct heat range.
When installing new spark plugs, be sure
that the ignition coils are clean and free
of any oil or debris. Clean and wipe off
the bottom portion of the ignition coil in
order to prevent any contamination with
the spark plug during installation.

when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction and
failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended Lubricants and
Capacities” section in chapter 2.)

Maintenance
9-18
NOTICE
To prevent damage to your engine:
• Do not spill engine oil when adding
or changing engine oil. Wipe off
spilled oil immediately.
• The engine oil consumption may
increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (6,000 km).
• The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it
if necessary.
Checking the Engine Oil and
Filter
• Have engine oil and filter changed
by an authorized HYUNDAI dealer
according to the Maintenance
Schedule at the beginning of this
chapter.
• If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.
• To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used, replace it according to the
maintenance schedule under severe
usage conditions.
• The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.

Maintenance
9-70
-Oil
Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natural
leather.
-Chewing gum
Harden the gum with ice and
remove gradually.
• Handling prime napa leather (if
equipped)
Try to avoid excessive sunlight and
heat exposure. Excessive sunlight
and heat exposure naturally fades
and dries out napa leather, causing
wrinkles and discoloration. If the napa
leather is wet with liquid, immediately
clean it with lint-free cloth to minimize
damage. Do not scratch the napa
leather surface with a sharp object.
If your napa leather seat is bright
colored, it may be contaminated or
stained from dyed materials such as
jeans.
Interior wooden trim
• Use a wooden furniture protector (e.g.
wax, coating compound) to clean the
interior wooden trim.
• Often wipe the interior wooden
trim with a lint-free, clean cloth to
maintain the unique wooden textures
for a longer period of time.
• If you spill beverage (e.g. water,
coffee) over the interior wooden trim,
immediately wipe it with clean, dry
cloth.
• Sharp objects (e.g. driver, knife),
adhesive materials, or tapes may
damage the interior wooden trim.
• Any strong impacts may damage the
interior wooden trim.
• If the coating finish over the interior
wooden trim is removed, moisture
may damage or change wood traits.
• If the interior wooden trim is
damaged, you may get a splinter
from the wood surface. Therefore,
you should immediately have the
damaged interior wooden trim
replaced by an authorized HYUNDAI
dealer.
Cleaning the seat belt webbing
Clean the belt webbing with any
mild soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the soap.
Do not bleach or re-dye the webbing
because this may weaken the seat belt.
Cleaning the interior window glass
If the interior glass surfaces of the
vehicle become fogged (that is, covered
with an oily, greasy or waxy film), they
should be cleaned with glass cleaner.
Follow the directions on the glass cleaner
container.
NOTICE
Do not scrape or scratch the inside of
the rear window. This may result in
damage to the rear window defroster
grid.
