inflation pressure NISSAN XTERRA 2014 N50 / 2.G Owners Manual

The driver supplemental front-impact air bag is
located in the center of the steering wheel. The
passenger supplemental front-impact air bag is
mounted in the dashboard above the glove box.
The front air bags are designed to inflate in higher
severity frontal collisions, although they may in-
flate if the forces in another type of collision are
similar to those of a higher severity frontal impact.
They may not inflate in certain frontal collisions.
Vehicle damage (or lack of it) is not always an
indication of proper front air bag system opera-
tion.
The NISSAN Advanced Air Bag System has dual
stage inflators. It also monitors information from
the crash zone sensor, the Air bag Control Unit
(ACU) , seat belt buckle sensors, occupant clas-
sification sensor (pressure sensor) and passen-
ger seat belt tension sensor. Inflator operation is
based on the severity of a collision and seat belt
usage for the driver. For the front passenger, it
additionally monitors the weight of an occupant
or object on the seat and seat belt tension. Based
on information from the sensors, only one front air
bag may inflate in a crash, depending on the
crash severity and whether the front occupants
are belted or unbelted. Additionally, the front
passenger air bag may be automatically turned
OFF under some conditions, depending on the
weight detected on the passenger seat and how
the seat belt is used. If the front passenger air bagis OFF, the passenger air bag status light will be
illuminated (if the seat is unoccupied, the light will
not be illuminated, but the air bag will be off) . See
“Front passenger air bag and status light” later in
this section for further details. One front air bag
inflating does not indicate improper performance
of the system.
If you have any questions about your air bag
system, please contact NISSAN or your NISSAN
dealer. If you are considering modification of your
vehicle due to a disability, you may also contact
NISSAN. Contact information is contained in the
front of this Owner’s Manual.
When a front air bag inflates, a fairly loud noise
may be heard, followed by the release of smoke.
This smoke is not harmful and does not indicate a
fire. Care should be taken to not inhale it, as it may
cause irritation and choking. Those with a history
of a breathing condition should get fresh air
promptly.
Front air bags, along with the use of seat belts,
help to cushion the impact force on the face and
chest of the front occupants. They can help save
lives and reduce serious injuries. However, an
inflating front air bag may cause facial abrasions
or other injuries. Front air bags do not provide
restraint to the lower body.
Even with NISSAN advanced air bags, seat belts
should be correctly worn and the driver and pas-
senger seated upright as far as practical away
from the steering wheel or instrument panel. The
front air bags inflate quickly in order to help
protect the front occupants. Because of this, the
force of the front air bag inflating can increase the
risk of injury if the occupant is too close to, or is
against, the front air bag module during inflation.
The front air bags deflate quickly after a collision.
The front air bags operate only when the
ignition switch is in the ON or START posi-
tion.
After placing the ignition switch in the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7 sec-
onds if the system is operational.
Safety—Seats, seat belts and supplemental restraint system1-53

If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meters and gauges
area of the instrument panel, will blink. Have the
system checked by a NISSAN dealer.
Other supplemental front-impact air bag
precautions
WARNING
● Do not place any objects on the steering
wheel pad or on the instrument panel.
Also, do not place any objects between
any occupant and the steering wheel or
instrument panel. Such objects may be-
come dangerous projectiles and cause
injury if the front air bags inflate.
● Immediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
● No unauthorized changes should be
made to any components or wiring of
the supplemental air bag system. This is
to prevent accidental inflation of the
supplemental air bag or damage to the
supplemental air bag system. ●
Do not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the front air bag system.
● Tampering with the front air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and above
the instrument panel or by installing
additional trim material around the air
bag system.
● Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing mate-
rial on the seat cushion or by installing
additional trim material, such as seat
covers, on the seat that are not specifi-
cally designed to assure proper air bag
operation. Additionally, do not stow any
objects under the front passenger seat
or the seat cushion and seatback. Such
objects may interfere with the proper
operation of the occupant classification
sensor (pressure sensor) . ●
No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect the
front air bag system. Tampering with
the seat belt system may result in seri-
ous personal injury.
● Work on and around the front air bag
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. The Supplemental Restraint
System (SRS) wiring should not be
modified or disconnected. Unauthor-
ized electrical test equipment and prob-
ing devices should not be used on the
air bag system.
● A cracked windshield should be re-
placed immediately by a qualified repair
facility. A cracked windshield could af-
fect the function of the supplemental air
bag system.
*The SRS wiring harness connectors are
yellow and orange for easy identification.
When selling your vehicle, we request that you
inform the buyer about the front air bag system
and guide the buyer to the appropriate sections
in this Owner’s Manual.
1-56Safety—Seats, seat belts and supplemental restraint system

●Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
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 your 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.
Starting and driving5-3

Additional information:● The TPMS does not monitor the tire
pressure of the spare tire.
● The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH
(25 km/h). Also, this system may not detect a
sudden drop in tire pressure (for example a
flat tire while driving) .
●
The low tire pressure warning light does not
automatically turn off when the tire pressure of
your tires are adjusted. After the tires are in-
flated to the recommended pressure, the ve-
hicle must be driven at speeds above 16 MPH
(25 km/h) to activate the TPMS and turn off the
low tire pressure warning light. Use a tire pres-
sure gauge to check the tire pressure.
●The CHECK TIRE PRES (pressure) warning
message is displayed in the odometer when
the low tire pressure warning light is illumi-
nated and low tire pressure is detected. The
CHECK TIRE PRES warning message turns
off when the low tire pressure warning light
turns off. The low tire pressure warning light
remains illuminated until the tires are inflated
to the recommended COLD tire pressure. The
CHECK TIRE PRES warning message is dis-
played each time the ignition switch is placed
in the ON position as long as the low tire
pressure warning light remains illuminated.
See “Check tire pressure warning message”
in the “Instruments and controls” section.
● The CHECK TIRE PRES warning is not dis-
played if the low tire pressure warning light
illuminates to indicate a TPMS malfunction.
● Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates, check
the tire pressure for all four tires.
● The Tire and Loading Information label (also
referred to as the vehicle placard or tire
inflation pressure label) is located in the
driver’s door opening.
For additional information, see “Low tire pressure
warning light” in the “Instruments and controls”
section and “Tire Pressure Monitoring System
(TPMS)” in the “In case of emergency” section.WARNING
● 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. (See “Flat tire” in the “In case
of emergency” section for changing a
flat tire.)
5-4Starting and driving

Tire inflation pressure
Check the tire pressures (including the
spare) often and always prior to long dis-
tance trips. The recommended tire pres-
sure specifications are shown on the
F.M.V.S.S./C.M.V.S.S. certification label
or the Tire and Loading Information label
under the “Cold Tire Pressure” heading.
The Tire and Loading Information label is
affixed to the driver side center pillar. Tire
pressures should be checked regularly
because:● Most tires naturally lose air over time.
● Tires can lose air suddenly when
driven over potholes or other objects
or if the vehicle strikes a curb while
parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or driven
less than 1 mile (1.6 km) at moderate
speeds. Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING
● Improperly inflated tires can fail
suddenly and cause an accident.
● The Gross Vehicle Weight Rating
(GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight ca-
pacity is indicated on the Tire and
Loading Information label. Do
not load your vehicle beyond this
capacity. Overloading your ve-
hicle may result in reduced tire
life, unsafe operating conditions
due to premature tire failure, or
unfavorable handling character-
istics and could also lead to a
serious accident. Loading beyond
the specified capacity may also
result in failure of other vehicle
components. ●
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 re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.

WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no
higher than the measured reference
height when the trailer is attached. If the
rear bumper is higher than the measured
reference height when loaded, the vehicle
may handle unpredictably which could
cause a loss of vehicle control and cause
serious personal injury or property
damage.
Sway control device
Sudden maneuvers, wind gusts, and buffeting
caused by other vehicles can affect trailer han-
dling. Sway control devices may be used to help
control these affects. If you choose to use one,
contact a reputable trailer hitch supplier to make
sure the sway control device will work with the
vehicle, hitch, trailer and the trailer’s brake sys-
tem. Follow the instructions provided by the
manufacturer for installing and using the sway
control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 2,000 lb (907 kg) .
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 3,500 lb (1,587 kg).
Class III hitch
Class III trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 5,000 lb (2,268 kg).
CAUTION
●Special hitches which include frame re-
inforcements are required for towing
above 2,000 lb (907 kg) . Suitable genu-
ine NISSAN hitches, ball mounts and
hitch balls for pickup trucks and sport
utility vehicles are available at a
NISSAN dealer.
● The hitch should not be attached to or
affect the operation of the impact-
absorbing bumper.
● Do not use axle-mounted hitches.
● Do not modify the vehicle exhaust sys-
tem, brake system, etc. to install a
trailer hitch. ●
To reduce the possibility of additional
damage if your vehicle is struck from
the rear, where practical, remove the
receiver when not in use.
● After the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
● Regularly check that all trailer hitch
mounting bolts are securely mounted.Tire pressures
● When towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire
and Loading Information label.
● Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer’s specifications.
Safety chains
Always use suitable safety chains between your
vehicle and the trailer. The safety chains should be
crossed and should be attached to the hitch, not to
the vehicle bumper or axle. Be sure to leave enough
slack in the chains to permit turning corners.
