HYUNDAI SONATA 2021 Owners Manual

Emergency Situations
7-16
When driving with the compact spare tire
mounted to your vehicle:
• Check the tire pressure after installing
the compact spare tire. The compact
spare tire should be inflated to 60 psi
(420 kPa).
• Do not take this vehicle through
an automatic car wash while the
compact spare tire is installed.
• Do not use the compact spare tire on
any other vehicle because this tire
has been designed especially for your
vehicle.
• The compact spare tire’s tread life is
shorter than a regular tire. Inspect
your compact spare tire regularly and
replace worn compact spare tires with
the same size and design, mounted on
the same wheel.
• Do not use more than one compact
spare tire at a time.
NOTICE
When the original tire and wheel are
repaired and reinstalled on the vehicle,
the lug nut torque must be set correctly.
The correct lug nut tightening torque is
79~94 lbf·ft (11~13 kgf·m).
CAUTION
To prevent damaging the compact
spare tire and your vehicle:
• Drive slowly enough for the road
conditions to avoid all hazards, such
as a potholes or debris.
• Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately 1
inch (25 mm).
• Do not use tire chains on the
compact spare tire. Because of the
smaller size, a tire chain will not fit
properly.
• Do not use the compact spare tire
on any other wheels, nor should
standard tires, snow tires, wheel
covers or trim rings be used with the
compact spare wheel.

Towing Service
ODN8079010L[A] : Dollies
If emergency towing is necessary,
we recommend having it done by
an authorized HYUNDAI dealer or a
commercial tow-truck service. Proper
lifting and towing procedures are
necessary to prevent damage to the
vehicle. The use of wheel dollies or
flatbed is recommended.
On 2WD vehicles, it is acceptable to
tow the vehicle with the rear wheels
on the ground (without dollies) and
the front wheels off the ground. If any
of the loaded wheels or suspension
components are damaged or the vehicle
is being towed with the front wheels on
the ground, use a towing dolly under the
front wheels.
When being towed by a commercial tow
truck and wheel dollies are not used,
the front of the vehicle should always be
lifted, not the rear.
CAUTION
• Do not tow the vehicle with the front
wheels on the ground as this may
cause damage to the vehicle.
ODN8079012L
• Do not tow with sling-type
equipment. Use a wheel lift or
flatbed equipment.

WARNING
If your vehicle is equipped with a
rollover sensor, place the ignition
switch in the LOCK/OFF or ACC position
when the vehicle is being towed.

situation as a rollover.
When towing your vehicle in an
emergency without wheel dollies:
1.
Place the ignition s
witch in the ACC
position.
2.

Place the shift butt
on in N (Neutral).
3.

R
elease the parking brake.
CAUTION
Failure to place the shift button in N
(Neutral) when being towed with the
front wheels on the ground can cause
internal damage to the transmission.
Emergency Towing
If towing is necessary, we recommend
you have it done by an authorized
HYUNDAI dealer or a commercial tow
truck service.

Maintenance
8-4
You should exercise the utmost care
to prevent damage to your vehicle and
injury to yourself whenever performing
any maintenance or inspection
procedures.
We recommend you have your
vehicle maintained and repaired by
an authorized HYUNDAI dealer. An
authorized HYUNDAI dealer meets
HYUNDAI’s high service quality
standards and receives technical support
from HYUNDAI in order to provide you
with a high level of service satisfaction.
Owner’s Responsibility
Maintenance service and record
retention are the owner’s responsibility.
You should retain documents that show
proper maintenance has been performed
on your vehicle in accordance with
the scheduled maintenance service
charts shown on the following pages.
You need this information to establish
your compliance with the servicing
and maintenance requirements of your
vehicle warranties.
Detailed warranty information is
provided in your Owner’s Handbook &
Warranty Information booklet.
Repairs and adjustments required as a
result of improper maintenance or a lack
of required maintenance are not covered.
Owner Maintenance Precautions
Inadequate, incomplete or insufficient
servicing may result in operational
problems with your vehicle that could
lead to vehicle damage, an accident, or
personal injury. This chapter provides
instructions only for the maintenance
items that are easy to perform. Several
procedures can be done only by an
authorized HYUNDAI dealer with special
tools.
Your vehicle should not be modified
in any way. Such modifications may
adversely affect the performance, safety
or durability of your vehicle and may, in
addition, violate conditions of the limited
warranties covering the vehicle.
Certain modifications may also be in
violation of regulations established by
the U.S. Department of Transportation
and other federal or state agencies.
NOTICE
Improper owner maintenance during
the warranty period may affect
warranty coverage. For details, read
the separate Owner’s Handbook &
Warranty Information booklet provided

WARNING
Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience or
the proper tools and equipment to do
the work, have it done by an authorized
HYUNDAI dealer.
ALWAYS follow these precautions for
performing maintenance work:
• Park your vehicle on level ground,
move the shift button into the P
(Park) position, place the ignition
switch in the LOCK/OFF position.
• Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.
• If you must run the engine during
maintenance, do so out doors or in
an area with plenty of ventilation.
• Keep flames, sparks, or smoking
materials away from the battery and
fuel-related parts. The following lists are vehicle checks and
inspections that should be performed
by the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged for
labor, parts and lubricants used.
Owner Maintenance Schedule

•
Check the engine oil level.
• Check the coolant level in the engine
coolant reservoir.
