2021 KIA RIO brake

745
Maintenance
Disc brake pads should be inspectedfor wear whenever tires are rotated.
Rotate radial tires that have an
asymmetric tread pattern only from
front to rear and not from right to left.
Wheel alignment and tire bal-
ance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced.
WARNING - Mixing tires
Do not use the compact spare tire (if equipped) for tire rota-
tion.
Do not mix bias ply and radial ply tires under any circum-
stances. This may cause
unusual handling characteris-
tics.
CAUTION - Wheel weight
Improper wheel weights candamage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.

Tire replacement
If the tire is worn evenly, a tread wear
Indicator (A) will appear as a solid
band across the tread. This shows
there is less than 1/16 inch (1.6 mm)
of tread left on the tire. Replace the
tire when this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire. The ABS works by comparing the
speed of the wheels. The tire size
affects wheel speed. When replacing
tires, all 4 tires must use the same
size originally supplied with the vehi-
cle. Using tires of a different size can
cause the ABS (Anti-lock Brake
System) and ESC (Electronic
Stability Control) to work irregularly.
✽ ✽

NOTICE
• We recommend that when replac-
ing tires, use the same which were
originally supplied with the vehi-
cle. If not, driving performance
could be altered.
• It is best to replace all four tires at the same time. If that is not possi-
ble, or necessary, then replace the
two front or two rear tires as a pair.
Replacing just one tire can serious-
ly affect your vehicle's handling.
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.

ed tire inflation pressure and shown
on the tire placard.
Radial Ply Tire: A pneumatic tire in
which the ply cords that extend to the
beads are laid at 90 degrees to the
centerline of the tread.
Rim: A metal support for a tire and

UTQGS: Uniform Tire Quality
Grading Standards, a tire information

ture and treadwear. Ratings are
determined by tire manufacturers
using government testing proce-
dures. The ratings are molded into
the sidewall of the tire.
Vehicle Capacity Weight: The num-
ber of designated seating positions
multiplied by 150 lbs. (68kg) plus the
rated cargo and luggage load. Vehicle Maximum Load on the
Tire:
Load on an individual tire due
to curb and accessory weight plus
maximum occupant and cargo
weight.
Vehicle Normal Load on the Tire:
Load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,

LIGHT BULBS
Bulb replacement precaution
Please keep extra bulbs on hand
with appropriate wattage ratings in
case of emergencies.
Refer to “Bulb Wattage” in chapter 8.
When changing lamps, first turn off
the engine at a safe place, firmly
apply the parking brake and detach
the battery’s negative (-) terminal.
Use only bulbs of the specified
wattage. net-work failure
The headlamp, taillight, and fog light
may light up when the head lamp
switch is turned ON, and not light up
when the taillight or for light switch is
turned ON. This may be cause by
network failure or vehicle electrical
control system malfunction. If there is
a problem, we recommend the sys-
tem be serviced by an authorized Kia
dealer.
trical control system stabilization
A normally functioning lamp may
flicker momentarily. This momentary
occurrence is due to stabilization
function of the vehicle's electrical on
control system. If the lamp soon
returns to normal, the vehicle does
not require service.
However, if the lamp goes out after
the momentary flickering, or the flick-
ering continues, we recommend the
system be serviced by an authorized
Kia dealer.
WARNING- Working on the lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the LOCK position
and turn off the lights to avoid
sudden movement of the vehi-
cle and burning your fingers or
receiving an electric shock.
CAUTION -Light replace-
ment
Be sure to replace the burned- out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.
CAUTION -Headlamp
Lens
To prevent damage, do notclean the headlamp lens withchemical solvents or strongdetergents.

APPEARANCE CARE
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label.
✽ ✽
NOTICE
If you park the vehicle around a
stainless signboard or windshield
building etc., the plastic exterior
trim (bumper, spoiler, garnish,
lamp, outside mirror etc.) may be
damaged by reflected sunlight from
the external structure. To avoid
damaging the plastic exterior trim,
park the vehicle away from the
areas where the reflected light may
occur or use a vehicle cover
(Depending on the vehicle, the type
of exterior trim applied such as
spoiler may differ).
Finish maintenance
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign mate-
rials. Make sure the drain holes in the
lower edges of the doors and rocker
panels are kept clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the finish.WARNING
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.

Maintenance
Underbody maintenance
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame. The National Highway Traffic
Safety Administration has warned all
vehicle owners of all brands of the
need to take the following steps:
Wash the undercarriage of yourvehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals. Do a thorough washing of the
undercarriage at the end of the
winter.
Use professional service techni- cians or governmental inspection
stations to annually inspect for cor-
rosion.
Immediately seek an inspection of your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Do not use any abrasive cleaner,polishing compound, solvent, or
wire brushes on aluminum wheels.
They may scratch the finish.
Clean the wheel when it has cooled.
Use only a mild soap or neutral detergent, and rinse thoroughly
with water. Also, be sure to clean
the wheels after driving on salted
roads. This helps prevent corro-
sion.
Avoid washing the wheels with highspeed vehicle wash brushes.
Do not use any alkaline or acid detergents as they may damage or
corrode aluminum wheels coated
with a clear protective finish.
