2021 NISSAN SENTRA ECO mode

Two-Wheel Drive models with
Continuously Variable
Transmission (CVT)
NISSAN recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed
truck as illustrated.

Two-Wheel Drive models with
manual transmission
NISSAN recommends that towing dollies
be used when towing your vehicle or place
the vehicle on the flatbed truck as illus-
trated.
If you must use a pull behind tow truck put
the manual transmission in N (Neutral).
Your vehicle speed should never exceed 60
mph (97 km/h) when towing your vehicle.
Af ter towing 500 miles, start and idle the
engine with the transmission in N (Neutral)
for two minutes. Failure to idle the engineaf ter every 500 miles of towing may cause
damage to the transmission’s internal
parts.

When installing Genuine NISSAN floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, theshif t lever in P (Park) position (Continu-
ously Variable Transmission models) or
the shif t lever in the N (Neutral) position
(manual transmission models) and with
the parking break fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the hook(s).
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is
properly positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shif t le-
ver in the P (Park) position (Continuously
Variable Transmission models) or the
shif t lever in the N (Neutral) position
(manual transmission models) and with
the parking break applied, fully apply
and release all pedals. The floor mat
must not interfere with pedal operation
or prevent the pedal from returning to
its normal position. It is recommended that you visit a NISSAN
dealer for details about installing the floor
mats in your vehicle.
The illustration shows the location of the
floor mat positioning hooks.
SEAT BELTS
The seat belts can be cleaned by wiping
them with a sponge dampened in a mild
soap solution. Allow the belts to dry com-
pletely in the shade before using them. For
additional information, refer to “Seat belt
maintenance” in the “Safety—Seats, seat
belts and supplemental restraint system”
section of this manual.

Tire and Loading Information
label
1Seating capacity: The maximum num-
ber of occupants that can be seated in
the vehicle.
2Original tire size: The size of the tires
originally installed on the vehicle at the
factory.
3Cold tire pressure: Inflate the tires to
this pressure when the tires are cold.
Tires are considered COLD af ter the ve-
hicle has been parked for 3 or more
hours, or driven less than 1 mile (1.6 km)
at moderate speeds. The recom- mended cold tire inflation is set by the
manufacturer to provide the best bal-
ance of tire wear, vehicle handling,
driveability, tire noise, etc., up to the ve-
hicle's GVWR.
4Tire size - refer to “Tire labeling” in this
section.
5Spare tire size.
6Vehicle load limit: Refer to “Vehicle load-
ing information” in the “Technical and
consumer information” section of this
manual.
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 sideways, or air will
escape. If the hissing sound of air escap-
ing from the tire is heard while checking
the pressure, reposition the gauge to
eliminate this leakage.
3. Remove the gauge.

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.
For additional traction on icy roads, stud-
ded 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.
TIRE CHAINS

This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a ve-
hicle's systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
• How various systems in your vehicle wereoperating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
These data can help provide a better un-
derstanding of the circumstances in which
crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-
trivial crash situation occurs; no data are
recorded by the EDR under normal driving
conditions and no personal data (e.g.
name, gender, age and crash location) are
recorded. However, other parties, such as law enforcement, could combine the EDR
data with the type of personally identif ying
data routinely acquired during a crash in-
vestigation.
To read data recorded by an EDR, special
equipment is required and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer and NISSAN
dealer, other parties, such as law enforce-
ment, that have the special equipment, can
read the information if they have access to
the vehicle or the EDR. EDR data will only be
accessed with the consent of the vehicle
owner or lessee or as otherwise required or
permitted by law.
