2023 HYUNDAI SANTA FE HYBRID maintenance schedule

Foreword / Hybrid System Overview1-6
Using Fuel Additives (except Detergent Fuel Additives)
Using fuel additives such as: - Silicone fuel additive
- Ferrocene (iron-based) fuel additive
- Other metallic-based fuel additives
may result in cylinder misfire, poor acceleration, engine stalling, damage to the
catalyst, or abnormal corrosion, and may cause damage to the engine resulting in a
reduction in the overall life of the powertrain.
- The Malfunction Indicator Lamp (MIL) may illuminate.
NOTICE
Damage to the fuel system or performance problem caused by the use of these fuels
may not be covered by your New Vehicle Limited Warranty.
Gasoline containing MMT
Some gasoline contains harmful manganese-based fuel additives such as MMT
(Methylcyclopentadienyl Manganese Tricarbonyl). HYUNDAI does not recommend the
use of gasoline containing MMT. This type of fuel can reduce vehicle performance and
affect your emission control system.
The malfunction indicator lamp on the cluster may come on.
Detergent Fuel Additives
HYUNDAI recommends that you use good quality gasolines treated with detergent
additives such as TOP TIER Detergent Gasoline, which help prevent deposit formation
in the engine. These gasolines will help the engine run cleaner and enha\
nce
performance of the Emission Control System. For more information on TOP TIER
Detergent Gasoline, please go to the website (www. toptiergas.com).
For customers who do not use TOP Tier Detergent Gasoline regularly, and have
problems starting or the engine does not run smoothly, detergent-based fuel additives
that you can purchase separately may be added to the gasoline. If TOP TIER Detergent
Gasoline is not available, one bottle of additive added to the fuel tank according to the
maintenance schedule is recommended (refer to the Maintenance Schedule in chapter
9).
Additives are available from your authorized HYUNDAI dealer along with information
on how to use them. Do not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle in another country, be sure to:

[ Observe all regulations regarding registration and insurance.

[ Determine that acceptable fuel is available.

Seats & Safety System3-2
You will find many safety precautions
and recommendations throughout this
section, and throughout this manual.
The safety precautions in this section are
among the most important.
Always Wear Your Seat Belt
A seat belt is your best protection in all
types of accidents. Air bags are designed
to supplement seat belts, not to replace
them. So even though your vehicle is
equipped with air bags, ALWAYS make
sure you and your passengers wear your
seat belts, and wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in a
rear seat, not the front seat. Infants and
small children should be restrained in
an appropriate Child Restraint System.
Larger children should use a booster
seat with the lap/shoulder belt until they
can use the seat belt properly without a
booster seat.
Air Bag Hazards
While air bags can save lives, they can
also cause serious or fatal injuries to
occupants who sit too close to them, or
who are not properly restrained. Infants,
young children, and short adults are at
the greatest risk of being injured by an
inflating air bag. Follow all instructions
and warnings in this manual.
Driver Distraction
Driver distraction presents a serious and
potentially deadly danger, especially for
inexperienced drivers. Safety should be
the first concern when behind the wheel
and drivers need to be aware of the wide
array of potential distractions, such as
drowsiness, reaching for objects, eating,
personal grooming, other passengers,
and using mobile phones. Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel to
focus on activities other than driving.
To reduce your risk of distraction and an
accident:

[
Set up your mobile devices (i.e., MP3
players, phones, navigation units, etc.)
ONLY when your vehicle is parked or
safely stopped.

[ ONLY use your mobile device when
allowed by laws and conditions permit
safe use. NEVER text or email while
driving. Most countries have laws
prohibiting drivers from texting. Some
countries and cities also prohibit
drivers from using handheld phones.

[ NEVER let the use of a mobile device
distract you from driving. You have a
responsibility to your passengers and
others on the road to always drive
safely, with your hands on the wheel
as well as your eyes and attention on
the road.
Control Your Speed
Excessive speed is a major factor in crash
injuries and deaths. Generally, the higher
the speed, the greater the risk, but
serious injuries can also occur at lower
speeds. Never drive faster than is safe
for current conditions, regardless of the
maximum speed posted.
Keep Your Vehicle in Safe
Condition
Having a tire blowout or a mechanical
failure can be extremely hazardous. To
reduce the possibility of such problems,
check your tire pressures and condition
frequently, and perform all regularly
scheduled maintenance.
IMPORTANT SAFETY PRECAUTIONS

Convenience Features5-106
System Maintenance
Cabin air filter
OIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
The cabin air filter be replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at an authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning system.
Therefore, if abnormal operation is found,
the system is inspected by an authorized
HYUNDAI dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.

Driving Your Vehicle6-38
All Wheel Drive (AWD) delivers engine
power to front and rear wheels for
maximum traction. AWD is useful when
extra traction is required, such as when
driving on, muddy, wet, or snow-covered
roads.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:

[ Do not drive in conditions that
exceed the vehicles intended
design such as challenging off-road
conditions.

[ Avoid high speeds when cornering or
turning.

[ Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.

[ The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.

[ Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.

[ In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the t ravel lanes.
NOTICE

[Do not drive in water if the level
is higher than the bottom of the
vehicle.

[ Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking return.

[ Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions"
section in chapter 9).

[ Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.

[ Be sure to equip the vehicle with four
tires of the same size and type.

[ Make sure that a full time AWD
vehicle is towed by a flat bed tow
truck.

Chain Installation
When installing tire chains, follow the
manuf
acturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:

[ Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.

[ Use SAE “S” class or wire chains.

[ If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.

[ To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).

[ Do not use tire chains on vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.

[ Use wire chains less than 0.47 in.
(12 mm) thick or fabric-type chain
to prevent damage to the chain’s
connection.

[ Fabric-type chains must be used on
vehicles equipped with 19/20” tires.
Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, you
consult an authorized HYUNDAI dealer.

6-65
Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your brakes and hold the brake pedal down
while you:

[ Start your engine;

[ Shift into gear; and

[ Release the parking brake.
2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance when Towing a
Trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:

[Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.

[ Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)

[ When towing check transmission
fluid more frequently.

[ If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
