2007 NISSAN SENTRA engine

Shift lock release
If the battery is discharged, the shift selector lever
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.
If the shift selector lever cannot be moved out of
P (Park) , have a NISSAN dealer check the trans-
mission as soon as possible.
WARNING
If the selector lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Overdrive (O/D) OFF switch
When the O/D OFF switch is pushed with the
selector lever in the D (Drive) position, the
light in the instrument panel illuminates. See
“Overdrive off indicator light” in the “Instruments
and controls” section of this manual.
Use the Overdrive off mode when you need im-
proved engine braking.
To turn off the Overdrive off mode, push the O/D
OFF switch again. The
indicator light will
turn off.

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) .

Shifting
To change gears, or when upshifting or down-
shifting, depress the clutch pedal fully, shift into
the appropriate gear, then release the clutch
slowly and smoothly.
To ensure smooth gear changes, fully depress
the clutch pedal before operating the shift lever. If
the clutch pedal is not fully depressed before the
transmission is shifted, a gear noise may be
heard. Transmission damage may occur.
Start the vehicle in 1st gear and shift to 2nd, 3rd,
4th and 5th up to 6th gear in sequence according
to vehicle speed.To back up, lift up on the shift lever ring
s1and
then move it to the R (Reverse) position after
stopping the vehicle completely.
The shift lever ring returns to its original position
when the shift lever is moved to the N (Neutral)
position.
If it is difficult to move the shift lever into R
(Reverse) or 1 (1st) , shift into N (Neutral) , then
release the clutch pedal. Depress the clutch
pedal again and shift into R (Reverse) or 1 (1st) .

cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
cDrive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
cAvoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
cAvoid unnecessary engine idling.
cKeep your engine tuned up.
cFollow the recommended periodic mainte-
nance schedule.
cKeep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
cKeep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.cWhen cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
cUse the recommended viscosity engine oil.

WARNING
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.
cSafe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park) for
CVT models or in an appropriate gear
for manual transmission models. Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shiftlever has been pushed as far forward as
it can go and cannot be moved without
depressing the foot brake pedal.
cNever leave the engine running while
the vehicle is unattended.
cDo not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
1. Firmly apply the parking brake.2.Manual transmission models:
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
Continuously Variable Transmission
(CVT) models:
Move the shift selector lever to the P (Park)
position.
3. To help prevent the vehicle from rolling into
traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
cHEADED DOWNHILL WITH CURB:
s1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
cHEADED UPHILL WITH CURB:
s2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
cHEADED UPHILL OR DOWNHILL, NO
CURB:
s3
Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter of the road if it moves.
