tires NISSAN SENTRA 2015 B17 / 7.G User Guide

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
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best braking
performance. This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
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.
BRAKE SYSTEM
5-30Starting and driving

– When installing a spare tire, makesure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to the ”Tire and load-
ing information label” in the “Techni-
cal and consumer information”
section of this manual.
– For additional information, refer to “Wheels and tires” in the “Mainte-
nance and 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 by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6mph(5
- 10 km/h). The speed varies according to road
conditions. When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies and releases hydraulic pressure. This action
is similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.

●Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or the
indicator light may
illuminate.

erly and the
indicator may flash or
the
indicator light may illuminate.
Do not drive on these types of roads.
● When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator may flash or
the
indicator light may illuminate.
This is not a malfunction. Restart the
engine after driving onto a stable
surface.
● If wheels or tires other than the NISSAN
recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or
the
indicator light may illuminate.
● The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns, the
system optimizes the distribution of force to each
of the four wheels depending on the radius of the
turn.
WARNING
● The VDC system is designed to help the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully.
● Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole, or use the remote keyless entry key fob or
the NISSAN Intelligent Key®.
ANTIFREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
antifreeze to assure proper winter protection. For
additional information, refer to “Engine cooling
system” in the “Maintenance and do-it-yourself”
section of this manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For additional information, refer to “Bat-
tery” in the “Maintenance and do-it-yourself” sec-
tion of this manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For additional information, refer to “Changing engine coolant” in the “Maintenance and do-it-
yourself” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires. 3. Tire chains may be used. For additional in- formation, refer to “Tire chains” in the “Main-
tenance and do-it-yourself” section of this
manual.
COLD WEATHER DRIVING

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the Tire Pressure
Monitoring System (TPMS) . It monitors tire pres-
sure of all tires except the spare. When the low
tire pressure warning light is lit, and the CHECK
TIRE PRES warning message is displayed in the
odometer, 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 activate only when the
vehicle is driven at speeds above 16 mph
(25 km/h). For additional information, refer to
“Warning/indicator lights and audible reminders”
in the “Instruments and controls” section, and
“Tire Pressure Monitoring System (TPMS)” in the
“Starting and driving” section 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.
● 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 after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting. ●
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.
FLAT TIRE
In case of emergency6-3

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.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.
Getting the spare tire and tools
1. Open the trunk. Lift the trunk floor carpeting and spare tire cover
A. Remove the jack
and the spare tire as indicated.
2. To remove the jack, take off the strap and lift out. If necessary, remove the spare tire first
to easily access the jack strap.

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.

6. Install the jack in its storage area and tightenthe jack strap.
7. Place the spare tire cover and the trunk floor carpeting over the damaged tire.
8. Close the trunk.
WARNING
● Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
● The spare tire is designed for emer-
gency use. Refer to specific instructions
under the heading “Wheels and tires” in
the “Maintenance and do-it-yourself”
section of this manual. To start your engine with a booster battery, the
instructions and precautions below must be fol-
lowed.
WARNING
●
If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
● Explosive hydrogen gas is always pres-
ent in the vicinity of the battery. Keep all
sparks and flames away from the
battery.
● Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
● Keep battery out of the reach of
children.
● The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.
