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 next
time the key is turned to the ON position, the light
in the instrument cluster of the selected shift
position will blink for approximately 8 seconds
after the ignition is turned ON. While the vehicle
can be driven under these circumstances, please
note that the automatic transmission will be
locked in third gear.
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. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition key
OFF and wait for 3 seconds. Then turn the
key back to the ON position. The vehicle
should return to its normal operating con-
dition. If it does not return to its normal
operating condition, have a NISSAN dealer
check the transmission and repair it if nec-
essary.
MANUAL TRANSMISSION
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

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
automatic transmission models or in an
appropriate gear for manual transmis-
sion models. Failure to do so could
cause the vehicle to move unexpectedly
or roll away and result in an accident.
Make sure the shift lever 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.
Automatic transmission 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:
sA
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
cHEADED UPHILL WITH CURB:
sB
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
