Rear corner radar
The rear corner radars are the sensors
inside the rear bumper for detecting the
side and rear areas. Always keep the rear
bumper clean for proper operation of the
system.
CAUTION
• The system may not work properly
when the bumper has been
damaged, or if the rear bumper has
been replaced or repaired.
• The sensing range differs somewhat
according to the width of the road.
When the road is narrow, the system
may detect other vehicles in the next
lane. On the other hand, when the
road is wide, the system may not
detect vehicles on both lanes and
may not warn.
• The system may turn off due to
strong electromagnetic waves.
• Always keep the sensors clean.
• NEVER arbitrarily disassemble the
sensor component nor apply any
impact on the sensor component.
• Be careful not to apply unnecessary
force on the radar sensor or sensor
cover. If the sensor is forcibly moved
out of proper alignment, the system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer. •
Do not apply foreign objects such as
a bumper sticker or a bumper guard
near the radar sensor or apply paint
to the sensor area. Doing so may
adversely affect the performance of
the sensor.
• NEVER install any accessories or
stickers on the front windshield, nor
tint the front windshield.
• Pay extreme caution to keep the
front view camera out of water.
• NEVER locate any reflective objects
(i.e. white paper, mirror) over the
crash pad. Any light reflection may
cause a malfunction of the system.

Maintenance8-38
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the tread
wear indicator bars on the tire. The
replacement compact spare tire should
be the same size and design tire as the
one provided with your new vehicle
and should be mounted on the same
compact spare tire wheel. The compact
spare tire is not designed to be mounted
on a regular size wheel, and the compact
spare tire wheel is not designed for
mounting a regular size tire.
WARNING
The original tire should be repaired or
replaced as soon as possible to avoid
failure of the spare and loss of vehicle
control resulting in an accident. The
compact spare tire is for emergency
use only. Do not operate your vehicle
over 50 mph (80 km/h) when using the
compact spare tire.
Wheel Replacement
When replacing the metal wheels for any
reason, make sure the new wheels are
equivalent to the original factory units in
diameter, rim width and offset.
Tire Traction
Tire traction can be reduced if you drive
on worn tires, tires that are improperly
inflated or on slippery road surfaces.
Tires should be replaced when the tread
depth is at least 2/32 inch (1.6 mm). To
reduce the possibility of losing control,
slow down whenever there is rain, snow
or ice on the road.
Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease tire
wear. If you find a tire is worn unevenly,
have your dealer check the wheel
alignment.
When you have new tires installed,
make sure they are balanced. This will
increase vehicle ride comfort and tire
life. Additionally, a tire should always
be rebalanced if it is removed from the
wheel.
Tire Sidewall Labeling
This information identifies and describes
the fundamental characteristics of
the tire and also provides the tire
identification number (TIN) for safety
standard certification. The TIN can be
used to identify the tire in case of a
recall.

1. Manufacturer or brand name
Manufacturer or brand name is shown.
2. Tire size designation
A tire’s sidewall is marked with a tire
size designation. You will need this
information when selecting replacement
tires for your car. The following explains
what the letters and numbers in the tire
size designation mean.
Example tire size designation:
(These numbers are provided as an
example only; your tire size designator
could vary depending on your vehicle.)

3. Checking tire life (TIN : Tire Identification Number)
Any tires that are over six years old,
based on the manufacturing date,
(including the spare tire) should be
replaced by new tires. You can find the
manufacturing date on the tire sidewall
(possibly on the inside of the wheel),
displaying the DOT Code. The DOT Code
is a series of numbers on a tire consisting
of numbers and English letters. The
manufacturing date is designated by the
last four digits (characters) of the DOT
code.
DOT : XXXX XXXX OOOO
The front part of the DOT shows a plant
code number, tire size and tread pattern
and the last four numbers indicate week
and year manufactured.
For example:
DOT XXXX XXXX 1419 represents that the
tire was produced in the 14th week of
2019.
4. Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include steel,
nylon, polyester, and others. The letter
“R” means radial ply construction; the
letter “D” means diagonal or bias ply
construction; and the letter “B” means
belted-bias ply construction.
5. Maximum permissible inflation pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer to
the Tire and Loading Information label
for recommended inflation pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that can be
carried by the tire. When replacing the
tires on the vehicle, always use a tire that
has the same load rating as the factory
installed tire.
7. Uniform tire quality grading
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width.
