2021 KIA NIRO HYBRID EV ignition

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.

WARNING- Electrical Fire
Always ensure replacements
fuses and relays are securely
fastened when installed. Failure
to do so can result in a vehicle
fire.
CAUTION
When replacing a blown fuse
or relay, make sure the new
fuse or relay fits tightly into
the clips. Failure to tightly
install the fuse or relay may
cause damage to the wiring
and electric systems.
Do not remove fuses, relays
and terminals fastened with
bolts or nuts. The fuses, relays
and terminals may not be fas-
tened correctly which may
cause vehicle damage.

Maintenance
Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
Use only UNLEADED FUEL for
gasoline engines.
Do not operate the vehicle when
there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
Do not misuse or abuse the
engine. Examples of misuse are
coasting with the ignition off and
descending steep grades in gear
with the ignition off.
Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
Do not modify or tamper with any
part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized Kia dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter.Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
