2007 NISSAN SENTRA check engine

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.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position, and wait approximately 10 sec-
onds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices.cMake sure the area around the vehicle is
clear.
cCheck fluid levels such as engine oil, cool-
ant, brake and clutch fluid, and window
washer fluid as frequently as possible, or at
least whenever you refuel.
cCheck that all windows and lights are clean.
cVisually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
cLock all doors.
cPosition seat and adjust head restraints.
cAdjust inside and outside mirrors.
cFasten seat belts and ask all passengers to
do likewise.
cCheck the operation of warning lights when

may not be moved from the P (Park) position even
with the brake pedal depressed.
To move the shift selector lever, release the shift
lock. The shift selector lever can be moved to N
(Neutral) . However, the steering wheel will be
locked unless the ignition switch is turned to the
ON position. This allows the vehicle to be moved
if the battery is discharged.
To push the shift lock release, complete the fol-
lowing procedure:1. Turn the ignition key to the LOCK position
and remove the key
2. Apply the parking brake.
3. Remove the shift lock release cover as
shown.
4. Insert a small screwdriver in the shift lock
release slot and push down.
5. Move the shift selector lever to the N (Neu-
tral) position while holding down the shift
lock release.
6. Turn the key to the ON position to unlock the
steering wheel. Now the vehicle may be
moved to the desired location.

D (Drive) , the Overdrive off mode will be auto-
matically turned off.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, the CVT will
not be shifted into the selected driving position.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction indicator light
(MIL)” in the “Instrument and controls” sec-
tion. This will occur even if all electrical
circuits are functioning properly. In this
case, turn the ignition switch to the OFF
position and wait for 10 seconds. Then turn
the switch back to the ON position. The
vehicle should return to its normal operat-
ing condition. If it does not return to its
normal operating condition, have a
NISSAN dealer check the transmission and
repair if necessary.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially care-
ful when driving. If necessary, pull to the
side of the road at a safe place and allow
the transmission to return to normal op-
eration, or have it repaired if necessary.
MANUAL TRANSMISSION (if so
equipped)
WARNING
cDo not downshift abruptly on slippery
roads. This may cause a loss of control.
cDo not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.
CAUTION
cDo not rest your foot on the clutch pedal
while driving. This may cause clutch
damage.
cFully depress the clutch pedal before
shifting to help prevent transmission
damage.
cStop your vehicle completely before
shifting into R (Reverse) .
cWhen the vehicle is stopped with the
engine running (for example, at a stop
light) , shift to N (Neutral) and release
the clutch pedal with the foot brake
applied.

vehicle at a set speed.
cIn heavy traffic or in traffic that varies in
speed.
cOn winding or hilly roads.
cOn slippery roads (rain, snow, ice, etc.) .
cIn very windy areas.
Doing so could cause a loss of vehicle
control and result in an accident.
CAUTION
On manual transmission models, do not
shift into N (Neutral) without depressing
the clutch pedal when the cruise control is

WARNING
cIf the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
cWhen the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle but the steering will be
harder to operate. Have the power
steering system checked by a NISSAN
dealer.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. When the temperature of the power steer-
ing system goes down, the power assist level will
return to normal. Avoid repeating such steering
wheel operations that could cause the power
steering system to overheat.You may hear a sound when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the power steering warning lightPSilluminates
while the engine is running, it may indicate the
power steering system is not functioning properly
and may need servicing. Have the power steering
system checked by a NISSAN dealer.
When the power steering warning light illumi-
nates with the engine running, there will be no
power assist for the steering but you will still have
control of the vehicle. At this time, greater steer-
ing effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information see “Power steering
warning light” in the “Instruments and controls”
section.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
brakes and 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
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.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) .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 oper-
ating. 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 required while driving.
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 keyfob (if so
equipped) .
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.
