1999 NISSAN SENTRA ignition

Suggested maximum speed in each
gear
Downshift to a lower gear if the engine is not
running smoothly, or if you need to acceler-
ate.
Do not exceed the maximum suggested
speed (shown below) in any gear. For level
road driving, use the highest gear sug-
gested for that speed. Always observe
posted speed limits, and drive according to
the road conditions, which will ensure safe
operation. Do not over-rev the engine when
shifting to a lower gear as it may cause
engine damage or loss of vehicle control.

2.Automatic transmission:
Move the shift selector lever to P (Park)
or N (Neutral). (P is recommended.)
The shift selector lever cannot be
moved out of P (Park) and into any of
the other gear positions if the ignition
key is turned to OFF or if the key is
removed.
The starter is designed not to operate
if the shift selector lever is in one of
the driving positions.
Manual transmission:
Move the selector lever to N (Neutral),
and depress the clutch pedal to the floor.
The starter is designed to operate
only when the clutch pedal is fully
depressed.
3. Crank the enginewith your foot off the
accelerator pedalby turning the ignition
key to START. Release the key when the
engine starts. If the engine starts, but
fails to run, repeat the above procedure.

Turn the wheels toward the side of the
road so the vehicle will move away from
the center of the road if it moves.
4. Turn the ignition key to the LOCK posi-
tion and remove the key.The power assisted steering is designed to
use a hydraulic pump, driven by the engine,
to assist steering.
If the engine stops or the drive belt breaks,
you will still have control of the vehicle.
However, much greater steering effort is
needed, especially in sharp turns and at low
speeds.
WARNING
If the engine is not running or is turned
off while driving the power assist for
the steering will not work. Steering will
be much harder to operate.The brake system has two separate hy-
draulic circuits. If one circuit develops a
problem, you will still have braking at
two wheels.
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 distance will be longer.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As a
result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats the brakes,

WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or to get caught in, the running
fan, belts, or fan motor. The fan motor
can start at any time when the coolant
temperature is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the res-
ervoir tank if necessary. Have your ve-
hicle repaired at an authorized NISSAN
dealer.When towing your vehicle, U.S States, Cana-
dian Provinces and local regulations for tow-
ing must be followed. Incorrect towing equip-
ment could damage your vehicle. Towing
instructions are available from an authorized
NISSAN dealer. Local service operators are
generally familiar with the applicable laws
and procedures for towing. To assure proper
towing and to prevent accidental damage to
your vehicle, NISSAN recommends having a
service operator tow your vehicle. It is advis-
able to have the service operator carefully
read the following precautions.
WARNING
cNever ride in a vehicle that is being
towed.
cNever get under your vehicle after it
has been lifted by a tow truck.
CAUTION
cWhen towing, make sure that the
transmission, axles, steering system
and powertrain are in working con-
dition. If any unit is damaged, dollies
must be used.cWhen towing manual transmission
models with the front wheels on the
ground (if you do not use towing
dollies):
Turn the ignition key to the OFF
position and secure the steering
wheel in a straight ahead position
with a rope or similar device. Never
place the ignition key in the LOCK
position. This will result in damage
to the steering lock mechanism.
Move the gearshift lever to the N
(Neutral) position.
cWhen towing with the rear wheels on
the ground, release the parking
brake.
cAttach safety chains for all towing.

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the gearshift
control lever to N (Neutral). For an
automatic transmission, move the
shift lever to P (Park).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cBe sure to turn the ignition key to the
OFF or LOCK position. When the
ignition key is in the ON or ACC
position, the cooling fan may start to
operate suddenly even when the en-
gine is not running.cIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
cIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it
is supported by only a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) sys-
tem, the fuel filter or fuel lines
should be serviced by an authorized
NISSAN dealer because the fuel
lines are under high pressure even
when the engine is off.
CAUTION
cDo not work under the hood while
the engine is hot. Turn the engine off
and wait until it cools down.
cNever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion is ON.
c
Avoid contact with used motor oil.
Improperly disposed motor oil and/or
other vehicle fluids can hurt the en-
vironment. Always conform to local
regulations for disposal of vehicle
fluid.
This ``Do-it-yourself'' section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect your warranty coverage.If in
doubt about any servicing, have it done
by an authorized NISSAN dealer.

If the belt is in poor condition or loose,
have it replaced or adjusted by an autho-
rized NISSAN dealer.

WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to
remove the spark plugs. An incorrect
socket can damage the spark plugs.
GA16DE Engine
1. Remove brackets as necessary to give
access to the high tension cables and
spark plugs.
2. Disconnect the spark plug cables from
the spark plugs.
When disconnecting, always hold the
boots, not the cables. Mark all cables to
identify their original locations.
3. Remove the spark plugs with a spark
plug socket.
The spark plug socket has a rubber seal
that holds the spark plug so it does not
fall when it is pulled out. Make sure each
spark plug is snugly fitted into the spark
plug socket.4. On conventional spark plugs, check the
gap on each new spark plug with a
feeler gauge.Use only the specified
spark plugs.(The spark plug gap is
shown in the ``Technical and consumer
information'' section of this manual.) Ad-
just the gap as required.
