Engine NISSAN SENTRA 1997 B14 / 4.G Owner's Manual

WARNING
Do not leave children, unreliable
adults, or pets alone in your vehicle.
They could accidentally injure them-
selves 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.
EXHAUST GAS (carbon monoxide)
WARNING
Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
cIf you suspect that exhaust fumes
are entering the vehicle, drive with
all windows 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 driv-
ing, otherwise exhaust gases could
be drawn into the passenger com-
partment. If you must drive in this
manner for some reason, take the
following steps:
1. Open all the windows.
2.
Set the air recirculation button (if
so equipped) off and the fan control
dial to 4 (high) to circulate the air.
3. Be sure the rear seats are secured
and latched in the upright
position.
cIf electrical wiring or other cable
connections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry 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 involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE WAY CATALYST
The three way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
c
The exhaust gas and the exhaust sys-
tem are very hot. Keep people or flam-
mable materials away from the ex-
haust pipe.
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.
PRECAUTIONS WHEN
STARTING AND DRIVING
4-2
ZX

CAUTION
cDo not use leaded gasoline. Depos-
its from leaded gasoline seriously
reduce the three way catalyst's abil-
ity to help reduce exhaust
pollutants.
cKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the converter,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by an authorized
NISSAN dealer.
cAvoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three way catalyst.
cDo not race the engine while warm-
ing it up.
cDo not push or tow your vehicle to
start the engine.WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss
of control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle.As with any vehicle, a loss
of control could result in a collision with
other vehicles or objects, or cause the
vehicle to rollover, particularly if the loss
of control causes the vehicle to slide
sideways.Be attentive at all times, and
avoid driving when tired. Never drive when
under the influence of alcohol or drugs
(including prescription or over-the-counter
drugs which may cause drowsiness). Al-
ways wear your seat belt as outlined in the
``Seat Belts'' section of this manual, and
also instruct your passengers to do so.WARNING
Never drive under the influence of alco-
hol or drugs. Alcohol in the blood
stream reduces coordination, delays
reaction time and impairs judgment.
Driving after drinking alcohol increases
the likelihood of being involved in an
accident injuring yourself and others.
Additionally, if you are injured in the
accident alcohol can increase the se-
verity of injury.
Nissan is committed to safe driving. How-
ever, you must choose not to drive under
the influence of alcohol. Every year thou-
sands of people are injured or killed in
alcohol related accidents. Although the local
laws vary on what is considered to be
legally intoxicated, the fact is that alcohol
affects all people differently and most
people underestimate the effects of alcohol.
Remember, drinking and driving don't mix!
And that's true for drugs, too (over the
counter, prescription, and illegal drugs).
Don't drive if your ability to operate your
vehicle is impaired by alcohol, drugs, or
some other physical condition.

ZX

The automatic transmission in your vehicle
is electronically controlled by the A/T control
unit to produce maximum power and
smooth operation.
The recommended operating procedures for
this transmission are shown on the following
pages. Follow these procedures for maximum
vehicle performance and driving enjoyment.
Starting the vehicle
cAfter starting the engine, fully depress
the foot brake pedal before shifting the
shift lever to the D, R, 2 or 1 position. Be
sure the vehicle is fully stopped before
attempting to shift the shift lever.
cKeep the foot brake pedal depressed and
shift into a driving gear.
c
Release the foot brake, then gradually
start the vehicle in motion.
The automatic transmission is designed
so the foot brake pedal MUST be de-
pressed before shifting from P to any drive
position while the ignition switch is ON.
The shift lever cannot be moved out of P
and into any of the other gear positions if
the ignition key is turned to LOCK or if
the key is removed.When the battery charge is low, the shift
lever can be moved if the ignition switch
is in the ACC position.
WARNING
cDo not depress the accelerator pedal
while shifting from P or N to R, D, 2
or 1. Always depress the brake pedal
until shifting is completed. Failure to
do so could cause you to lose con-
trol and have an accident.
cCold engine idle speed is high, so
use caution when shifting into a for-
ward or reverse gear before the en-
gine has warmed up.
cNever shift to P or R while the ve-
hicle is moving. This could cause an
accident.
cOn slippery roads, do not downshift.
This may cause a loss of control.
CAUTION
When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing the accelerator pedal. The foot
brake should be used for this purpose.
DRIVING WITH AUTOMATIC
TRANSMISSION
(if so equipped)

ZX

Shifting with automatic transmission
Push the button to shift into P, R or from D
to 2. All other positions can be selected
without pushing the button.
P (Park):
Use this selector position when the vehicle
is parked or when starting the engine. Al-
ways be sure the vehicle is at a complete
stop. For maximum safety, depress the
brake pedal, then push in the shift lever
button and move the lever to the P position.
Apply the parking brake. When parking on a
hill, apply the parking brake first, then shift
the lever into the P position.
Shifting from P (Park)
If the ignition switch is in the ON position
and the foot brake pedal is depressed, but
the shift lever still cannot be moved out of P
(Park), follow these instructions:
1. Shut the engine off and remove the key.
2. Apply the parking brake.
3. Reinsert the key and turn it clockwise to
the ACC position.
4.
Depress the brake pedal, move the shift
lever to N (Neutral) and start the engine.
5. Check stop lights operation.
WARNING
If the shift lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is de-
pressed, the stop lights may not work.
Malfunctioning stop lights could cause
an accident injuring yourself and others.
These instructions for starting the vehicle in
N (Neutral) should only be used until service
can be obtained. Never drive the vehicle if
the stop lights are not operating properly.
R (Reverse):
Use this position to back up. Always be sure
the vehicle is completely stopped. With the
brake pedal depressed, push in the shift
lever button and move the lever to the R
position.
N (Neutral):
Neither forward nor reverse gear is en-
gaged. The engine can be started in this
position. You may shift to N and restart a
stalled engine while the vehicle is moving.
D (Drive):
Use this position for all normal forward
driving.

2 (Second gear):
Use for hill climbing or engine braking on
downhill grades.
Do not shift into the 2 position at speeds
over 68 MPH (110 km/h). Do not exceed 68
MPH (110 km/h) in the 2 position.
1 (Low gear):
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
sand or mud, or for maximum engine brak-
ing on steep downhill grades.
Do not shift into the 1 position at speeds
over 34 MPH (55 km/h).
Do not exceed 34 MPH (55 km/h) in the 1
position.
Accelerator downshift
Ð In D position Ð
For rapid passing or hill climbing, fully de-
press the accelerator pedal to the floor. This
shifts the transmission down into third gear,
second gear or first gear, depending on the
vehicle speed.
Overdrive switch
ON: For normal driving, push the over-
drive switch ON with the shift lever in
the D position. The transmission is
upshifted into OVERDRIVE as the
vehicle speed increases.
The overdrive does not engage until the
engine has warmed up.
OFF: For driving up and down long slopes
where engine braking would be ad-
vantageous, push the switch OFF.
When cruising at a low speed or
climbing a gentle slope, you may feeluncomfortable shift shocks as the
transmission shifts between 3rd and
overdrive repeatedly. In this case,
set the overdrive switch in the
OFF position. The indicator
light in the instrument panel comes
on at this time.
When driving conditions change, reset the
overdrive switch in the ON position.
Remember not to drive at high speeds for
extended periods of time with the overdrive
switch set in the OFF position. This reduces
fuel economy.

Shifting with manual transmission
To change gears, fully depress the clutch
pedal, then move the gearshift lever. After
shifting, release the clutch pedal slowly.
You cannot shift directly from 5th gear into
Reverse (R). First shift into Neutral (N), then
into Reverse (R).
If it is difficult to move the gearshift lever into
R or 1st, shift into N, then release and
depress the clutch pedal again and shift into
R or 1st.
WARNING
cDo not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
cDo not over-rev the engine when
shifting 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.
cStop your vehicle completely before
shifting into Reverse.
cWhen the vehicle is stopped for a
duration, for example at a stop light,
shift to N and release the clutch
pedal with the foot brake applied.
