2016 NISSAN SENTRA ECU

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 automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedure:1. Leave the ignition switch in the ON position 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 device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in
an emergency. (The engine will stop when
the ignition switch is pushed 3 consecu-
tive times in quick succession or the igni-
tion 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 de-
pressing the brake pedal or the clutch pedal
(MT) , the ignition switch position will illuminate 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 return 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 switched to OFF until
the shift lever is moved to the P (Park) position or
N (Neutral) position (MT) .
When the ignition switch cannot be pushed to-
ward the OFF position, proceed as follows: 1. Move the shift lever into the P (Park) position or N (Neutral) position (MT) .
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.

WARNING
●Make sure the parking brake is securely
applied and the manual transmission is
shifted into R (Reverse) , or the CVT is
shifted into P (Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
A. Blocks
B. Flat tire
Blocking wheels
Place suitable blocks at both the front and back
of the wheel diagonally opposite the flat tire to
prevent the vehicle from moving when it is jacked
up.

●Use the correct jack-up points. Never
use any other part of the vehicle for jack
support.
● Never jack up the vehicle more than
necessary.
● Never use blocks on or under the jack.
● Do not start or run the engine while
vehicle is on the jack. It may cause the
vehicle to move. This is especially true
for vehicles with limited slip
differentials.
● Do not allow passengers to stay in the
vehicle while it is on the jack.
● Never run the engine with a wheel(s) off
the ground. It may cause the vehicle to
move. Always refer to the proper illustrations for the
correct placement and jack-up points for your
specific vehicle model and jack type.
Carefully read the caution label attached to
the jack body and the following instruc-
tions.
1. Loosen each wheel nut one or two turns by turning counterclockwise with the wheel nut
wrench. Do not remove the wheel nuts
until the tire is off the ground.
2. Place the jack directly under the jack-up point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.
Align the jack head between the two notches in the front or the rear as shown.
Also fit the groove of the jack head between
the notches as shown.
The jack should be used on firm and
level ground.
3. To lift the vehicle, securely hold the jack lever and rod with both hands. Carefully raise the
vehicle until the tire clears the ground. Re-
move the wheel nuts and then remove the
tire.

Installing the spare tire
The spare tire is designed for emergency
use. For additional information, refer to
“Wheels and tires” in the “Maintenance
and do-it-yourself” section of this manual.1. Clean any mud or dirt from the surface be- tween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the sequence
illustrated (
A,B,C,D,E) until they are
tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated (
A,B,C,D,
E) . Lower the vehicle completely.
WARNING
●Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
● Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
● Retighten the wheel nuts when the ve-
hicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque: 83 ft-lb (113 N·m)
The wheel nuts must be kept tightened to
specification at all times. It is recom-
mended that wheel nuts be tightened to
specification at each lubrication interval. Adjust tire pressure to the COLD pressure.
COLD pressure: After vehicle has been
parked for 3 hours or more or driven less
than 1 mile (1.6 km) .
COLD tire pressures are shown on the Tire
and Loading Information Label.
After adjusting tire pressure to the COLD
tire pressure, the display of the tire pres-
sure information may show higher pres-
sure than the COLD tire pressure after the
vehicle has been driven more than 1 mile
(1.6 km) .
This is because the tire pressurizes as the
tire temperature rises. This does not indi-
cate a system malfunction.
5. Securely store the flat tire in the vehicle.

CAUTION
●Never tow Continuously Variable Trans-
mission (CVT) models with the front
wheels on the ground or 4 wheels on
the ground (forward or backward) , as
this may cause serious and expensive
damage to the transmission. If it is nec-
essary to tow the vehicle with the rear
wheels raised always use towing dollies
under the front wheels.
● When towing Continuously Variable
Transmission (CVT) models with the
front wheels on towing dollies, or when
towing Manual Transmission (M/T)
models with the front wheels on the
ground:
– Place the ignition switch to the OFF position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may damage the steering
lock mechanism (for models with
steering lock mechanism) .
– Move the shift lever to the N (Neutral) position. ●
When towing Continuously Variable
Transmission (CVT) or Manual Trans-
mission (M/T) models with the rear
wheels on the ground (if you do not use
towing dollies): Always release the
parking brake.
● Observe the following restricted towing
speeds and distances for Manual Trans-
missions (M/T) only:
– Speed: Below 80 km/h (50 mph)
– Distance: Less than 80 km (50 miles)
VEHICLE RECOVERY (freeing a stuck
vehicle)
WARNING
To avoid vehicle damage, serious personal
injury or death when recovering a stuck

In case of emergency6-13

Your NISSAN is designed to have minimum main-
tenance requirements with long service intervals
to save you both time and money; however, some
day-to-day and regular maintenance is essential
to maintain your NISSAN’s good mechanical
condition as well as its emissions and engine
performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide”. You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly as prescribed.Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected. It is recommended that
you visit a NISSAN dealer for this service.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hicles
before they work on your vehicle rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, it is
recommended that you visit a NISSAN dealer if
you think that repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
Additional information on the following
items with“*”isfound in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood
