2017 NISSAN ALTIMA SEDAN tire size

To increase your confidence in the seat belts,
check the operation as follows:● Grasp the shoulder belt and pull forward
quickly. The retractor should lock and re-
strict further belt movement.
If the retractor does not lock during this check,
get the system checked. It is recommended that
you visit a NISSAN dealer for this service or to
learn more about seat belt operation.
Shoulder belt height adjustment (front
seats)
The shoulder belt anchor height should be ad-
justed to the position best for you. For additional
information, refer to “Precautions on seat belt
usage” in this section. To adjust, pull out the
adjustment button
1and move the shoulder belt
anchor to the desired position
2, so the belt
passes over the center of the shoulder. The belt
should be away from your face and neck, but not
falling off your shoulder. Release the adjustment
button to lock the shoulder belt anchor into posi-
tion.
WARNING
● After adjustment, release the adjust-
ment button and try to move the shoul-
der belt anchor up and down to make
sure it is securely fixed in position.
● The shoulder belt anchor height should
be adjusted to the position best for you.
Failure to do so may reduce the effec-
tiveness of the entire restraint system
and increase the chance or severity of
injury in an accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it is
not possible to properly fit the lap/shoulder belt
and fasten it, an extender that is compatible with
the installed seat belts is available for purchase.
The extender adds approximately 8 in (200 mm)
of length and may be used for either the driver or
front passenger seating position. It is recom-
mended that you visit a NISSAN dealer for assis-
tance with purchasing an extender if an extender
is required.LRS0242

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 light does not illuminate with the
ignition switch placed in the ON posi-
tion, have the vehicle checked as soon
as possible. It is recommended that you
visit a NISSAN dealer for this service. ●
If the 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 in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could result
in serious personal injury or death.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label
located in the driver’s door opening to
turn the low tire pressure warning light
off. If the light still illuminates while
driving after 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 recommended that you
visit a NISSAN dealer for this service. ●
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 1 minute. The light will remain
on after 1 minute. Have your tires re-
placed 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.
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.
Instruments and controls2-13

CAUTION
●Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
● Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly. It is recommended that you
visit a NISSAN dealer for this service.
● Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
● Do not race the engine while warming it
up.
● Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly
under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check all four tires as soon as possible, and
inflate them to the proper pressure. Driving on a
significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists. When the malfunction indicator is
illuminated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons,
including the installation of replacement or alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Starting and driving5-3

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. 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.
BRAKE SYSTEM
5-78Starting 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 “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. 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.
Starting and driving5-79

Do not attach stickers (including transparent ma-
terial) , install accessories or apply additional
paint near the sonar sensors.
Do not strike or damage the area around the
sonar sensors. It is recommended that you visit a
NISSAN dealer if the area around the sonar sen-
sors is damaged due to a collision.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 function on
the 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 “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 “Do-it-yourself” section 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 “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. It is
recommended that you visit a NISSAN
dealer for the tire type, size, speed rating and
availability information.
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 “Do-it-
yourself” section of this manual.
COLD WEATHER DRIVING

●Before taking a long trip, or whenever
you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.
● For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.

Checking tire pressure
1. Remove the valve stem cap from the
tire.
2. Press the pressure gauge squarely onto the valve stem. Do not press too
hard or force the valve stem side-
ways, or air will escape. If the hissing
sound of air escaping from the tire is
heard while checking the pressure,
reposition the gauge to eliminate this
leakage.
3. Remove the gauge. 4. Read the tire pressure on the gauge
stem and compare to the specifica-
tion shown on the Tire and Loading
Information label.
5. Add air to the tire as needed. If too much air is added, press the core of
the valve stem briefly with the tip of
the gauge stem to release pressure.
Recheck the pressure and add or
release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.
