transmission fluid KIA NIRO HYBRID EV 2021 Owners Manual

Emergency towing precautions
Turn the ignition switch to ACC so
the steering wheel isn’t locked.
Place the transmission shift lever in
N (Neutral).
Release the parking bake.
Press the brake pedal with more
force than normal since you will
have reduced brake performance.
More steering effort will be
required because the power steer-
ing system will be disabled.
If you are driving down a long hill,
the brakes may overheat and brake
performance will be reduced. Stop
often and let the brakes cool off.
The vehicle should be towed at a
speed of 25 km/h (15 mph) or less
within the distance of 20 km (12
miles). If the car is being towed with all
four wheels on the ground, it can
be towed only from the front. Be
sure that the transmission is in N
(Neutral). Be sure the steering is
unlocked by placing the ignition
switch in the ACC position. A driver
must be in the towed vehicle to
operate the steering and brakes.
CAUTION - Dual clutch
transmission
To avoid serious damage to the
dual clutch transmission, limit
the vehicle speed to 15 km/h
(10 mph) and drive less than
1.5 km (1 mile) when towing.
Before towing, check the dual
clutch transmission for fluid
leaks under your vehicle. If the
dual clutch transmission fluid
is leaking, flatbed equipment
or a towing dolly must be
used.

Maintenance
OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized Kia dealer at the frequencies
indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolant
reservoir.
Check the windshield washer fluid
level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
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 dual clutch 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).
WARNING- Hot coolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure.
WARNING
When you open the engine
hood, turn the Hybrid system
off. If not, it may result in death
or serious injury because of the
high voltage flow.

Maintenance
8 7
At least monthly:
Check the coolant level in the
engine coolant reservoir.
Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flash-
ers.
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.
At least twice a year
(i.e., every Spring and Fall) :
Check the radiator, heater and air
conditioning hoses for leaks or
damage.
Check the windshield washer
spray and wiper operation. Clean
the wiper blades with clean cloth
dampened with washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes,
shields and clamps.
Check the lap/shoulder belts for
wear and function.
At least once a year :
Clean the body and door drain
holes.
Lubricate the door hinges and
check the hood hinges.
Lubricate the door and hood locks
and latches.
Lubricate the door rubber weather-
strips.
Check the air conditioning system.
Inspect and lubricate dual clutch
transmission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level.

Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections for
leakage and damage. Replace any
damaged parts.
Coolant (Engine / Inverter)
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.

Specifications, Consumer information and Reporting safety defects
RECOMMENDED LUBRICANTS AND CAPACITIES
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
These lubricants and fluids are recommended for use in your vehicle.
*1: Refer to the recommended SAE viscosity numbers on the next page.
*2: Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
*
3: To maintain your vehicle’s best brake and ABS/ESC performance, use Kia genuine brake fluid as in the specification.
