2011 NISSAN ALTIMA COUPE tire size

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.
Shoulder belt guide (Coupe)
The shoulder arm can be adjusted to allow easier
access to the shoulder belt. The arm can also be
folded down to allow rear seat passengers easier
access.
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 that can be
purchased. The extender adds approximately 8 in
(200 mm) of length and may be used for either
the driver or front passenger seating position. See a NISSAN dealer for assistance with pur-
chasing an extender if an extender is required.
WARNING
●
Only NISSAN seat belt extenders, made
by the same company which made the
original equipment seat belts, should
be used with NISSAN seat belts.
● Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use could
result in serious personal injury in the
event of an accident.
● Never use seat belt extenders to install
child restraints. If the child restraint is
not secured properly, the child could be
seriously injured in a collision or a sud-
den stop.
SEAT BELT MAINTENANCE
● To clean the seat belt webbing, apply a
mild soap solution or any solution recom-
mended for cleaning upholstery or carpet.
Then wipe with a cloth and allow the seat
belts to dry in the shade. Do not allow the
seat belts to retract until they are completely
dry.
LRS0821
1-20Safety—Seats, seat belts and supplemental restraint system

●If dirt builds up in the shoulder belt
guide of the seat belt anchors, the seat
belts may retract slowly. Wipe the shoulder
belt guide with a clean, dry cloth.
● Periodically check to see that the seat
belt and the metal components, such as
buckles, tongues, retractors, flexible wires
and anchors, work properly. If loose parts,
deterioration, cuts or other damage on the
webbing is found, the entire seat belt as-
sembly should be replaced. Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available from
many other sources, including doctors, teachers,
government traffic safety offices, and community
organizations. Every child is different, so be sure
to learn the best way to transport your child.
There are three basic types of child restraint
systems:
● Rear-facing child restraint
● Forward-facing child restraint
● Booster seat
The proper restraint depends on the child’s size.
Generally, infants up to about 1 year and less
than 20 lbs (9 kg) should be placed in rear-facing
child restraints. Forward-facing child restraints
are available for children who outgrow rear-
facing child restraints and are at least 1 year old.
Booster seats are used to help position a vehicle
lap/shoulder belt on a child who can no longer
use a forward-facing child restraint.WARNING
Infants and children need special protec-
tion. The vehicle’s seat belts may not fit
them properly. The shoulder belt may
come too close to the face or neck. The
lap belt may not fit over their small hip
bones. In an accident, an improperly fit-
ting seat belt could cause serious or fatal
injury. Always use appropriate child
restraints.
All U.S. states and Canadian provinces or terri-
tories require the use of approved child restraints
for infants and small children. See “Child re-
straints” later in this section.
A child restraint may be secured in the vehicle by
using either the LATCH (Lower Anchor and Teth-
ers for CHildren) system or with the vehicle seat
belt. See the “Child restraints” section for more
information.
NISSAN recommends that all pre-teens
and children be restrained in the rear seat.
Studies show that children are safer when
properly restrained in the rear seat than in
the front seat.

TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
placed in the ON position. The light will remain on
after the 1 minute. Have the system checked by a
NISSAN dealer. The CHECK TIRE PRESSURE
warning does not appear if the low tire pressure
warning light illuminates to indicate a TPMS mal-
function.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and “Tire pressure” in the “Main-
tenance and do-it-yourself” section.
WARNING
●If the light does not illuminate with the
ignition switch placed in the ON posi-
tion, have the vehicle checked by a
NISSAN dealer as soon as possible. ●
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 re-
sult in serious personal injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
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. If you have a flat tire, re-
place it with a spare tire as soon as
possible. ●
When a spare tire is mounted or a wheel
is replaced tire pressure will not be in-
dicated, 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. Con-
tact 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.
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 4 wheels correctly.
Master warning light
This light comes on when various vehicle infor-
mation display warnings appear.
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 by a NISSAN dealer.
● 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 4 tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat 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.

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances 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 vehicle in front
of you. Ultimately, the driver is respon-
sible 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. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see “Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery 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.

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.
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “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 details, see “Battery” in the “Main-
tenance and 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 details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide 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 details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
● A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
● A sturdy, flat board to be placed under the
jack to give it firm support.
● A shovel to dig the vehicle out of snowdrifts.
● Extra washer fluid to refill the windshield-
washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
●Wet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify the tire in case of a
recall.
