2021 NISSAN SENTRA open hood

•If the light illuminates while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle
speed, pull off the road to a safe loca-
tion 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 acci-
dent and could result in serious per-
sonal injury or death. Check the tire
pressure for all four tires. Adjust the
tire pressure to the recommended
COLD tire pressure show on the Tire
and Loading Information label lo-
cated in the driver’s door opening to
turn the low tire pressure warning
light off. If the light still illuminates
while driving af ter adjusting the tire
pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a spare
tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit a NISSAN
dealer for this service. •
When replacing a wheel without the
TPMS such as the spare tire, 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 system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for these services.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure
to check the tire pressure regularly.
• If the vehicle is being driven at
speeds of less than 16 mph (25 km/h),
the TPMS may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.

Your vehicle may have two types of security
systems:
• Vehicle security system (if so equipped)
• NISSAN Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM (if so
equipped)
The vehicle security system provides visual
and audible alarm signals if someone
opens the doors when the system is
armed. It is not, however, a motion detec-
tion type system that activates when a ve-
hicle is moved or when a vibration occurs.The system helps detect vehicle thef t but
cannot prevent it, nor can it prevent the
thef t of interior or exterior vehicle compo-
nents in all situations. Always secure your
vehicle even if parking for a brief period.
Never leave your keys in the ignition, and
always lock the vehicle when unattended.
Be aware of your surroundings, and park in
secure, well-lit areas whenever possible.
Many devices offering additional protec-
tion, such as component locks, identifica-
tion markers, and tracking systems, are
available at auto supply stores and spe-
cialty shops. A NISSAN dealer may also offer
such equipment. Check with your insur-
ance company to see if you may be eligible
for discounts for various thef t protection
features.
How to arm the vehicle security
system
1. Close all windows and the moonroof.
The system can be armed even if the
windows and moonroof are open.
2. Remove the Intelligent Key from the vehicle. 3. Close all doors, hood and trunk. Lock all
doors. The doors can be locked with the
Intelligent Key, door handle request
switch (if so equipped), power door lock
switch or mechanical key (if so
equipped).
4. Wait 30 seconds for the system to com- plete the pre-armed phase.
If during the pre-armed phase one of
the following occurs, the system will not
arm:
• Any door is unlocked with the me- chanical key (if so equipped), Intelli-
gent Key or door request switch (if so
equipped).
• The ignition switch is placed in the AUTO ACC or ON position.
• Even when the driver and/or passen-
gers are in the vehicle, the system will
activate when all the doors, hood and
trunk are locked with the ignition
switch placed in the LOCK position.
When placing the ignition switch in the
ON position, the system will be re-
leased.

The Remote Engine Start operating range
is approximately 197 f t (60 m) from the ve-
hicle.
REMOTE STARTING THE VEHICLE
To use the Remote Engine Start feature to
start the engine perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Press the
button to lock all doors.
3. Within 5 seconds press and hold the
button until the turn signal lights
flash and the tail lamps turn on. If the
vehicle is not within view press and hold
the
button for at least 2 seconds.
The following events will occur when the
engine starts:
• The parking lights will turn on and remain on as long as the engine is running.
• The doors will be locked and the climate control system may come on.
• The engine will continue to run for 10 min- utes. Repeat the steps to extend the time
for an additional 10 minutes. For addi-
tional information, refer to “Extending en-
gine run time” in this section.
Depress and hold the brake then push the
push-button ignition switch to the ON po-
sition before driving. For additional infor- mation, refer to “Driving the vehicle” in the
“Starting and driving” section of this

EXTENDING ENGINE RUN TIME
The Remote Engine Start feature can be
extended one time by performing the
steps listed in “Remote starting the vehicle”
in this section. Run time will be calculated
as follows:
• The first 10 minute run time will start
when the Remote Engine Start function is
performed.
• The second 10 minutes will start immedi- ately when the Remote Engine Start
function is performed again. For example,
if the engine has been running for 5 min-
utes, and 10 minutes are added, the en-
gine will run for a total of 15 minutes.
• Extending engine run time will bring you to the two Remote Engine Start limit.
A maximum of two Remote Engine Starts,
or a single start with an extension, are al-
lowed between ignition cycles.
The ignition switch must be cycled to the
ON position and then back to the OFF po-
sition before the Remote Engine Start pro-
cedure can be used again.

3-22Pre-driving checks and adjustments

secondary latch keeps the hood from
opening when the primary latch is re-
leased.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing the tires, make sure no wheel nuts are
missing, and check for any loose wheel
nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated ev-
ery 7,500 miles (12,000 km).
Tires*: Check the pressure with a gauge
of ten and always prior to long distance
trips. If necessary, adjust the pressure in all
tires, including the spare, to the pressure
specified. Check carefully for damage, cuts
or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the
TPMS transmitter grommet seal, valve core
and cap when the tires are replaced due to
wear or age. Wheel alignment and balance:
If the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may
be a need for wheel alignment. If the steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield: Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind-
shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to
http://collision.nissanusa.com.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe properly.Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled maintenance,
cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer
to stop, have your vehicle checked imme-
diately. It is recommended that you visit a
NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission
(CVT) P (Park) position mechanism (if so
equipped): On a fairly steep hill check that
the vehicle is held securely with the shif t
lever in the P (Park) position without apply-
ing any brakes.
