warning light NISSAN SENTRA 2021 Workshop Manual

•If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Driving with under-inflated tires may
permanently damage the tires and
increase the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light off. If you have
a flat tire, replace it with a spare tire
as soon as possible. (For additional
information on changing a flat tire,
refer to “Flat tire” in the “In case of
emergency ” section of this manual.) •
When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is
replaced, the TPMS will not function
and the low tire pressure warning
light will flash for approximately 1
minute. The light will remain on af ter
1 minute. Have your tires replaced
and/or TPMS reset as soon as pos-
sible. It is recommended that you
visit a NISSAN dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
• Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-
sure sensors.
CAUTION
Do not place metalized film or any
metal parts (antenna, etc.) on the win-
dows. This may cause poor reception of
the signals from the tire pressure sen-
sors, and the TPMS will not function
properly. Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate.
Some examples are:
• Facilities or electric devices using similar
radio frequencies are near the vehicle.
• If a transmitter set to similar frequencies is being used in or near the vehicle.
• If a computer (or similar equipment) or a DC/AC converter is being used in or near
the vehicle.
The low tire pressure warning light may
illuminate in the following cases:
• If the vehicle is equipped with a wheel and tire without TPMS.
• If the TPMS has been replaced and the ID has not been registered.
• If the wheel is not originally specified by NISSAN.

WARNING
Do not operate the push-button igni-
tion switch while driving the vehicle ex-
cept in an emergency. (The engine will
stop when the ignition switch is pushed
three consecutive times in quick suc-
cession or the ignition switch is pushed
and held for more than 2 seconds.) If
the engine stops while the vehicle is
being driven, this could lead to a crash
and serious injury. When the ignition switch is pushed without
depressing the brake pedal or the clutch
pedal for manual transmission (M/T) mod-
els, the ignition switch position will illumi-
nate as follows:
Push center:
• Once to change to ACC.
• Two times to change to ON.
• Three times to return to OFF.
The ignition switch will automatically re-
turn to the LOCK position when any door is
either opened or closed with the switch in
the OFF position.
The ignition lock is designed so that the
ignition switch position cannot be placed
in the OFF position until the shif t lever is
moved to the P (Park) position or N (Neutral)
position (M/T).
When the ignition switch cannot be pushed
toward the OFF position, proceed as fol-
lows:
1. Move the shif t lever to the P (Park) posi-
tion or N (Neutral) position (M/T).
2. Push the ignition switch. The ignition switch position will change to the ON
position. 3. Push the ignition switch again to the
OFF position.
The shif t lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.
If the battery of the vehicle is discharged,
the ignition switch cannot be moved
from the LOCK position.
Some indicators and warnings for opera-
tion are displayed in the meter. For addi-
tional information, refer to “Warning lights,
indicator lights and audible reminders” in
the “Instruments and controls” section of
this manual.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake and clutch fluid (if so equipped),
and windshield-washer fluid as fre-
quently as possible, or at least whenever
you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Lock all doors.
• Position seat and adjust head restraints/ headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2.
Continuously Variable Transmission
model:
Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t lever is in any of the driving
positions.
Manual Transmission (M/T) model:
Move the shif t lever to N (Neutral). De-
press the clutch pedal to the floor.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and the

OFF position:
For normal driving and fuel economy, use
the OFF position.
ON position:
For driving up or down long slopes where
engine braking is necessary, or for powerful
acceleration, use the ON position. The
transmission will automatically select a dif-
ferent gear ratio, allowing the engine to
provide high output.
Remember not to drive at high speeds for
extended periods of time with the drive
sport mode in the ON position. This re-
duces fuel economy.
Accelerator downshif t
— in D (Drive) position —
For passing or hill climbing, depress the
accelerator pedal to the floor. This shif ts
the transmission down into a lower gear,
depending on the vehicle speed.
Fail-safe
If the vehicle is driven under extreme
conditions, such as excessive wheel
spinning and subsequent hard braking,
the fail-safe system may be activated.
The Malfunction Indicator Light (MIL)may come on to indicate the fail-safe
mode is activated. For additional infor-
mation, refer to “Malfunction Indicator
Light (MIL)” in the “Instruments and con-
trols” section of this manual. This will oc-
cur even if all electrical circuits are func-
tioning properly. In this case, place the
ignition switch in the OFF position and
wait for 10 seconds. Then push the
switch back to the ON position. The ve-
hicle should return to its normal operat-
ing condition. If it does not return to its
normal operating condition, have the
transmission checked and repaired, if
necessary. It is recommended that you
visit a NISSAN dealer for this service.
WARNING
When the high fluid temperature pro-
tection mode or fail-safe operation oc-
curs, vehicle speed may be gradually
reduced. The reduced speed may be
lower than other traffic, which could in-
crease the chance of a collision. Be es-
pecially careful when driving. If neces-
sary, pull to the side of the road at a safe
place and allow the transmission to re-
turn to normal operation, or have it re-
paired if necessary.
MANUAL TRANSMISSION (if so
equipped)
CAUTION
• Do not rest your foot on the clutch
pedal while driving. This may cause
clutch damage.
• Fully depress the clutch pedal before
shif ting to help prevent transmission
damage.
• Stop your vehicle completely before
shif ting into R (Reverse).
