ECU HYUNDAI SANTA FE 2022 Service Manual

Driving your vehicle
6-4
Before entering the vehicle

[Be sure all windows, outside mirror(s),
and outside lights are clean and
unobstructed.

[Remove frost, snow, or ice.

[Visually check the tires for uneven
wear and damage.

[Check under the vehicle for any sign
of leaks.

[Be sure there are no obstacles behind
you if you intend to back up.
Before starting

[Make sure the hood, the liftgate, and
the doors are securely closed and
locked.

[Adjust the position of the seat and
steering wheel.

[Adjust the inside and side view
mirrors.

[Verify all the lights work.

[Fasten your seat belt. Check that all
passengers have fastened their seat
belts.

[Check the gauges and indicators
in the instrument panel and the
messages on the instrument display
when the ignition switch is in the ON
position.

[Check that any items you are carrying
are stored properly or fastened down
securely.
WARNING
To reduce the risk of SERIOUS INJURY or
DEATH, take the following precautions:

[ALWAYS wear your seat belt. All
passengers must be properly belted
whenever the vehicle is moving.
For more information, refer to “Seat
Belts” section in chapter 3.

[Always drive defensively. Assume
other drivers or pedestrians may be
careless and make mistakes.

[Stay focused on the task of driving.
Driver distraction can cause
accidents.

[Leave plenty of space between you
and the vehicle in front of you.
WARNING
NEVER drink or take drugs and drive.
Drinking or taking drugs and driving
is dangerous and may result in an
accident and SERIOUS INJURY or
DEATH.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don’t drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.
BEFORE DRIVING

Safety chains
You should always attach chains between
your vehicle and your trailer.
Instructions about safety chains may
be provided by the hitch manufacturer
or trailer manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave just
enough slack so you can turn with your
trailer. And, never allow safety chains to
drag on the ground.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to
your country’s regulations and that
it is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes loaded, then it needs its own
brakes and they must be adequate. Be
sure to read and follow the instructions
for the trailer brakes so you’ll be able
to install, adjust and maintain them
properly. Be sure not to modify your
vehicle’s brake system.
WARNING
Do not use a trailer with its own brakes
unless you are absolutely certain that
you have properly set up the brake
system. This is not a task for amateurs.
Use an experienced, competent trailer
shop for this work.
Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get to
know your trailer. Acquaint yourself with
the feel of handling and braking with the
added weight of the trailer. And always
keep in mind that the vehicle you are
driving is now longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector(s), lights, tires and brakes.
During your trip, occasionally check
to be sure that the load is secure, and
that the lights and trailer brakes are still
working.
Distance
Stay at least twice as far behind the
vehicle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up
ahead when you’re towing a trailer. And,
because of the increased vehicle length,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.

Certification label
OBH059070
The certification label is located on the
driver's door sill at the center pillar and
shows the maximum allowable weight of
the fully loaded vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle,
all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle, including
all occupants, accessories, cargo, and
trailer tongue load must not exceed the
Gross Vehicle Weight Rating (GVWR) or
the Gross Axle Weight Rating (GAWR).
To find out the actual loads on your front
and rear axles, you need to go to a weigh
station and weigh your vehicle. Be sure
to spread out your load equally on both
sides of the centerline.
WARNING
Overloading

[Never exceed the GVWR for your
vehicle, the GAWR for either the front
or rear axle and vehicle capacity
weight. Exceeding these ratings
can affect your vehicle's handling
and braking ability, and cause an
accident.

[Do not overload your vehicle.
Overloading your vehicle can cause
heat buildup in your vehicle's tires
and possible tire failure, increased
stopping distances and poor vehicle
handling-all of which may result in a
crash.
NOTICE
Overloading your vehicle may cause
damage. Repairs would not be covered
by your warranty. Do not overload your
vehicle.
WARNING
If you carry items inside your vehicle
(for example, suitcases, tools, packages,
or anything else), they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash, the
items will keep going and can cause
an injury if they strike the driver or a
passenger.

[Put items in the cargo area of your
vehicle. Try to spread the weight
evenly.

[Do not stack items, like suitcases,
inside the vehicle above the tops of
the seats.

[Do not leave an unsecured child
restraint in your vehicle.

[When you carry something inside the
vehicle, secure it.

WARNING
Wheels may have sharp edges. Handle
them carefully to avoid possible severe
injury. Before putting the wheel into
place, be sure that there is nothing on
the hub or wheel (such as mud, tar,
gravel, etc.) that interferes with the
wheel from fitting solidly against the
hub.
If there is, remove it. If there is not
good contact on the mounting surface
between the wheel and hub, the wheel
nuts could come loose and cause the
loss of a wheel. Loss of a wheel may
result in loss of control of the vehicle.
This may cause serious injury or death.
10. To reinstall the wheel, hold it on the
studs, put the wheel nuts on the studs
and tighten them finger tight. The
nuts should be installed with their
tapered small diameter ends directed
inward. Jiggle the tire to be sure it is
completely seated, then tighten the
nuts as much as possible with your
fingers again.
11. Lower the vehicle to the ground
by turning the wheel lug wrench
counterclockwise.
OTM080045LOTM080045L
12. Use the wheel lug wrench to tighten
the wheel bolts in the order shown.
Double-check each wheel bolts until
they are tight. After changing tires,
have an authorized HYUNDAI dealer
tighten the wheel bolts to their proper
torque as soon as possible. The wheel
bolt should be tightened to 79~94
lbf.ft (11~13 kgf.m).
If you have a tire gauge, check the
tire pressure (see “Tires and Wheels”
section in chapter 2 for tire pressure
instructions.). If the pressure is lower or
higher than recommended, drive slowly
to the nearest service station and adjust
it to the recommended pressure. Always
reinstall the valve cap after checking
or adjusting tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy another
and install it as soon as possible. After
changing tires, secure the flat tire and
return the jack and tools to their proper
storage locations.

NOTICE
Check the tire pressure as soon as
possible after installing a spare tire.
Adjust it to the recommended pressure.
CAUTION
Your vehicle has metric threads on the
studs and wheel bolts. Make certain
during tire changing that the same bolts
that were removed are reinstalled. If
you have to replace your wheel bolts
make sure they have metric threads to
avoid damaging the studs and ensure
the wheel is properly secured to the
hub. Consult an authorized HYUNDAI
dealer for assistance.
WARNING
Wheel studs
If the studs are damaged, they may lose
their ability to retain the wheel. This
could lead to the loss of the wheel and a
collision resulting in serious injuries.
If any of the equipment such as the jack,
wheel bolts, studs, or other equipment
is damaged or in poor condition, do not
attempt to change the tire and call for
assistance.
Use of compact spare tires
(if equipped)
Compact spare tires are designed for
emergency use only. Drive carefully on
the compact spare tire and always follow
the safety precautions.
WARNING
To prevent compact spare tire failure
and loss of control possibly resulting in
an accident:
• Use the compact spare tire only in an
emergency.
• NEVER operate your vehicle over 50
mph (80 km/h).
• Do not exceed the vehicle’s
maximum load rating or the load
carrying capacity shown on the
sidewall of the compact spare tire.
• Do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to
avoid failure of the compact spare
tire.

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.
Have an authorized HYUNDAI dealer
replace any damaged or leaking parts
immediately.
Fuel filter (for gasoline engine)
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. 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. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
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.
