Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
Check the coolant level in the
engine coolant reservoir.
Check the windshield washer fluid level.
Check the tire for low or under- inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of exhaust
fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

Tire Care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.

Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire pressure for your vehicle can
be found in this manual and
on the tire label located on the
driver’s side center pillar.
Always use a tire pressure
gauge to measure tire pres-
sure. Tires with too much or
too little pressure wear
unevenly causing poor han-
dling.
Check the pressure of the spare every time you check
the pressure of the other tires
on your vehicle.
Replace tires that are worn, show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering) control, or
traction.
ALWAYS replace tires with the same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle's Anti-Lock Brake System
(ABS) resulting in a serious
accident.

Maintenance
Recommended Cold Tire
Inflation Pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. "Cold tires" means the
vehicle has not been driven for at
least three hours or driven less than
one mile (1.6 km).
Warm tires normally exceed recom-
mended cold tire pressures by 4 to 6
psi (28 to 41 kPa). Do not release air
from warm tires to adjust the pres-
sure or the tires will be under-inflat-
ed. For recommended inflation pres-
sure, refer to "Tire and Wheels" in
chapter 8. Under-inflation results in exces-
sive wear, poor handling and
reduced fuel economy. Wheel
deformation is also possible.
Keep your tire pressures at the
proper levels. If a tire frequently
needs refilling, have it checked by
an authorized retailer of Genesis
Branded products.
Over-inflation produces a harsh ride, excessive wear at the cen-
ter of the tire tread, and a greater
possibility of damage from road
hazards.
NOTICE
Recommended pressures must
be maintained for the best ride,
vehicle handling, and minimum
tire wear.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
could result in loss of vehicle
control resulting in an accident.
Severe under-inflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
resulting in an accident. This
risk is much higher on hot days
and when driving for long peri-
ods at high speeds.

Check Tire Inflation Pressure
Check your tires, including the spare
tire, once a month or more.
How to check
Use a good quality tire pressure
gauge to check tire pressure. You
can not tell if your tires are properly
inflated simply by looking at them.
Radial tires may look properly inflat-
ed when they are under-inflated.
Remove the valve cap from the tire
valve stem. Press the tire gauge firm-
ly onto the valve to get a pressure
measurement. If the cold tire inflation
pressure matches the recommended
pressure on the tire and loading
information label, no further adjust-
ment is necessary. If the pressure is
low, add air until you reach the rec-
ommended pressure. Make sure to
put the valve caps back on the valve
stems. Without the valve cap, dirt or
moisture could get into the valve
core and cause air leakage. If a valve
cap is missing, install a new one as
soon as possible.
If you overfill the tire, release air by
pushing on the metal stem in the
center of the tire valve. Recheck the
tire pressure with the tire gauge. Be
sure to put the valve caps back on
the valve stems. Without the valve
cap, dirt or moisture could get into
the valve core and cause air leakage.
If a valve cap is missing, install a new
one as soon as possible.
Tire Rotation
To equalize tread wear, Genesis
Branded Vehicle recommends that
the tires be rotated every 7,500 miles
(12,000 km) or sooner if irregular
wear develops.
During rotation, check the tires for
correct balance.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of-balance wheels, severe braking or
severe cornering. Look for bumps or
bulges in the tread or side of tire.
Replace the tire if you find either of
these conditions. Replace the tire if
fabric or cord is visible. After rotation,
be sure to bring the front and rear tire
pressures to specification and check
lug nut tightness (proper torque is
79~94 lbf·ft [11~13 kgf·m]).

7-42
Maintenance
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 mount-
ing a regular size 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 tread wear indicators
appear. 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 charac-
teristics 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.
The original tire should be
repaired or replaced as soon as
possible to avoid failure of the
spare and loss of vehicle con-
trol resulting in an accident. The
compact spare tire is for emer-
gency use only. Do not operate
your vehicle over 50 mph (80
km/h) when using the compact
spare tire.
WARNING

Maintenance
3. Checking tire life (TIN : TireIdentification Number)
Any tires that are over six years old,
based on the manufacturing date,
(including the spare tire) should be
replaced by new ones. 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 num-
bers on a tire consisting of numbers
and English letters. The manufactur-
ing date is designated by the last four
digits (characters) of the DOT code.
DOT : XXXX XXXX OOOO
The front part of the DOT means a
plant code number, tire size and
tread pattern and the last four num-
bers indicate week and year manu-
factured.
For example:
DOT XXXX XXXX 2719 represents
that the tire was produced in the 27th
week of 2019.
4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-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 con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-tion 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.

7-46
Maintenance
Temperature - A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grade C
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.
Tire Terminology and
