warning lights NISSAN SENTRA 2021 Owner's Guide

•Only touch the base when handling
the bulb. Never touch the glass enve-
lope. Touching the glass could sig-
nificantly affect bulb life and/or
headlight performance.
• High pressure halogen gas is sealed
inside the halogen bulb. The bulb
may break if the glass envelope is
scratched or the bulb is dropped.
• Use the same number and wattage
as shown in the chart.
WARNING
Do not touch bulb by hand while it is lit
or right af ter being turned off. Burning
may result.
CAUTION
• Do not touch glass surface of the bulb
with bare hands or allow oil or grease to
get on it to prevent damage to bulb.
• Do not leave the bulb out of the lamp
reflector for a long time because dust,
moisture, smoke, etc. may affect the
performance of the lamp.
• Fog may temporarily form inside the
lens of the exterior lights in the rain or in a car wash. A temperature difference
between the inside and the outside of
the lens causes the fog. This is not a
malfunction. If large drops of water col-
lect inside the lens, it is recommended
that you visit a NISSAN dealer for ser-
vicing.

Parking brake:Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.
Steering wheel: Check for changes in the
steering system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*:
Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery*: This vehicle is equipped with a
sealed maintenance free battery. It is rec-
ommended that you visit a NISSAN dealer
for service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances. In these cases, the battery may need to
be charged to maintain battery health.
Brake and clutch (if so equipped) fluid
level*:
Make sure that the brake and clutch
fluid levels are between the MIN and MAX
lines on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belt*: Make sure the drive belt
is not frayed, worn, cracked or oily.
Engine oil level*: Check the level af ter
parking the vehicle on a level surface with
the engine off. Wait more than 15 minutes
for the oil to drain back into the oil pan.
Exhaust system: Make sure there are no
loose supports, cracks or holes. If the
sound of the exhaust seems unusual or
there is a smell of exhaust fumes, immedi-
ately have the exhaust system inspected. It
is recommended that you visit a NISSAN
dealer for this service. For additional infor-
mation, refer to “Exhaust gas (carbon mon-
oxide)” in the “Starting and driving” section
of this manual.
