2007 NISSAN ALTIMA engine

WARNING
cDo not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
cClosely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
cDo not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death.cIf you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
cDo not run the engine in closed spaces
such as a garage.
cDo not park the vehicle with the engine
running for any extended length of time.
cKeep the trunk lid closed while driving,
otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the trunk lid
open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
cIf electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the trunk lid or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle.
cThe exhaust system and body should be
inspected by a qualified mechanic
whenever:a. The vehicle is raised for service.
b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of
the exhaust system.
d. You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
cThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
cDo 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
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
cKeep 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.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo 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.
Additional information:
cThe TPMS does not monitor the tire pres-
sure of the spare tire.
