service NISSAN SENTRA 2017 B17 / 7.G Workshop Manual

WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
If the vehicle is driven under extreme con-
ditions, 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 indi-
cate the fail-safe mode is activated. For
additional information, refer to “Malfunc-
tion Indicator Light (MIL)” in the “Instru-
ment and controls” section of this manual.
This will occur even if all electrical circuits
are functioning properly. In this case, place
the ignition switch in the OFF position and
wait for 10 seconds. Then push the switchback to the ON position. The vehicle should
return to its normal operating condition. If
it does not return to its normal operating
condition, have the transmission checked
and repaired, if necessary. It is recom-
mended that you visit a NISSAN dealer for
this service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially careful
when driving. If necessary, pull to the side
of the road at a safe place and allow the
transmission to return to normal opera-
tion, or have it repaired if necessary.
MANUAL TRANSMISSION (if so
equipped)
WARNING
●
Do not downshift abruptly on slippery
roads. This may cause a loss of control.
● Do not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage. ●
Do not shift to the N (Neutral) position
while driving. Doing so may result in an
accident due to loss of engine braking.
CAUTION
● Do not rest your foot on the clutch pedal
while driving. This may cause clutch
damage.
● Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
● Stop your vehicle completely before
shifting into R (Reverse) .
● When the vehicle is stopped with the
engine running (for example, at a stop
light) , shift to N (Neutral) and release
the clutch pedal with the foot brake
applied.
● Do not shift to the N (Neutral) position
while driving. Doing so may result in an
accident due to loss of engine braking.

●To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or
death to people and pets.
1. Firmly apply the parking brake.
2. MT models
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
CVT models
Move the shift lever into the P (Park) posi-
tion.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
● HEADED DOWNHILL WITH CURB
1:
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb. ●
HEADED UPHILL WITH CURB
2:
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
● HEADED UPHILL OR DOWNHILL, NO
CURB
3:
Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter of the road if it moves.
4. Place the ignition switch in the LOCK posi- tion and remove the key.
WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN dealer
for this service.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. When the temperature of the power steer-
ing system goes down, the power assist level will
return to normal. Avoid repeating such steering

wheel operations that could cause the power
steering system to overheat.
You may hear a sound when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the electric power steering warning light illumi-
nates while the engine is running, it may indicate
the power steering system is not functioning
properly and may need servicing. Have the power
steering system checked. It is recommended that
you visit a NISSAN dealer for this service.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering, but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
●
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
BRAKE SYSTEM
5-72Starting and driving

This procedure is described in the vehicle service
manual. It is recommended that you visit a
NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
● Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels. – When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to “Tire and Loading
Information label” in the “Technical
and consumer information” section
of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself” section of this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking on
slippery surfaces. The system detects the rota-
tion speed at each wheel and varies the brake
fluid pressure to prevent each wheel from locking
and sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain steering
control and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked. It is recommended that you visit a
NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above3-6mph(5
- 10 km/h). The speed varies according to road
conditions.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with TPMS. It monitors
tire pressure of all tires except the spare. When
the low tire pressure warning light is lit, and the
“CHECK TIRE PRES” (vehicles without a vehicle
information display) also appears in the trip com-
puter or the “Tire Pressure Low - Add Air” (ve-
hicles with a vehicle information display) appears
in the vehicle information display, one or more of
your tires is significantly under-inflated. If the
vehicle is being driven with low tire pressure, the
TPMS will activate and warn you of it by the low
tire pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights and
audible reminders” in the “Instruments and con-
trols” section, and “Tire Pressure Monitoring Sys-
tem (TPMS)” in the “Starting and driving” sec-
tions of this manual.
WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use. ●
If the low tire pressure warning light
illuminates while driving, avoid sudden
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 pressure
shown on the Tire and Loading Informa-
tion 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.
● Since the spare tire is not equipped with
the TPMS, 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 approxi-
mately one minute. The light will remain
on after one minute. Have your tires
replaced and/or TPMS system reset as
soon as possible. It is recommended
that you visit a NISSAN dealer for these
services. ●
Replacing tires with those not originally
specified by NISSAN could affect 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 pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Shift the manual transmission into R
(Reverse) , or the CVT into P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
