ANTENNA
The antenna cannot be shortened, but can be
removed. When you need to remove the antenna,
turn the antenna rod counterclockwise.
To install the antenna rod, turn the antenna clock-
wise. Tighten the antenna rod to specification
using a suitable tool such as an open-end
wrench. The antenna rod tightening specification
is 3.4 - 3.6 N·m (30 - 32 in-lb) . Do not use pliers
to tighten the antenna as they can leave marks on
the antenna surface. The antenna rod cannot be
hand tightened to the proper specification.
CAUTION
Always properly tighten the antenna rod
during installation or the antenna rod may
break during vehicle operation.When installing a CB, ham radio or car phone in
your NISSAN, be sure to observe the following
cautions, otherwise the new equipment may ad-
versely affect the MFI (Multiport Fuel Injection)
system and other electronic parts.
WARNING
cA cellular telephone should not be used
while driving so full attention may be
given to vehicle operation. Some juris-
dictions prohibit the use of cellular tele-
phones while driving.
cIf you must make a call while your ve-
hicle is in motion, the hands free cellu-
lar phone operational mode (if so
equipped) is highly recommended. Ex-
ercise extreme caution at all times so
full attention may be given to vehicle
operation.
cIf a conversation in a moving vehicle
requires you to take notes, pull off the
road to a safe location and stop your
vehicle before doing so.
CAUTION
cKeep the antenna as far away as pos-
sible from the Engine Control Module
(ECM) .cKeep the antenna wire more than 8 in
(20 cm) away from the Multiport Fuel
Injection harness. Do not route the an-
tenna wire next to any harness.
cAdjust the antenna standing-wave ratio
as recommended by the manufacturer.
cConnect the ground wire from the CB
radio chassis to the body.
cFor details, consult a NISSAN dealer.

MEMO

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.
AVOIDING COLLISION AND
ROLLOVER
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 ma-
neuvers, because these driving practices could
cause you to lose control of your vehicle.As with
any vehicle, loss of control could result in a
collision with other vehicles or objects, or
cause the vehicle to roll over, 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 pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental air bags” section of this manual,
and also instruct your passengers to do so.
Seat belts help reduce the risk of injury in collisions
and rollovers.In a rollover crash, an unbelted
or improperly belted person is significantly
more likely to be injured or killed than a
person properly wearing a seat belt.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood
of being involved in an accident injuring
yourself and others. Additionally, if you
are injured in an accident, alcohol can
increase the severity of the injury.
NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related accidents. Al-
though 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 is true for drugs, too (over-the-counter, pre-
scription, and illegal drugs) . Don’t drive if your
ability to operate your vehicle is impaired by alco-
hol, drugs, or some other physical condition.

If the shift selector lever cannot be moved out of
P (Park) , have a NISSAN dealer check the auto-
matic transmission system as soon as possible.
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.
Overdrive switch
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and the
shift selector lever in the D (Drive)
position, the transmission upshifts
into Overdrive as vehicle speed
increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down long
slopes where engine braking is nec-
essary push the Overdrive switch
once. The O/D OFF indicator light
in the instrument panel comes on at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts into and out of
Overdrive repeatedly. In this case, depress the
Overdrive switch to turn the Overdrive off. The
O/D OFF indicator light in the instrument panel
comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
Remember not to drive at high speeds for ex-
tended periods of time with the Overdrive off.
This reduces fuel economy.

PRECAUTIONS ON CRUISE
CONTROL
cIf the cruise control system malfunctions, it
cancels automatically. The SET indicator
light in the instrument panel then blinks to
warn the driver.
cIf the SET indicator light blinks, turn the
cruise control main switch off and have the
system checked by a NISSAN dealer.cThe SET indicator light may blink when the
cruise control main switch is turned ON
while pushing the RES/ACCEL,
SET/COAST, or CANCEL switch (located
on the steering wheel) . To properly set the
cruise control system, use the following pro-
cedures.
WARNING
Do not use the cruise control when driving
under the following conditions:
cWhen it is not possible to keep the
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 set.
Should this occur, depress the clutch pedal
and turn the main switch off immediately.
Failure to do so may cause engine damage.
CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed be-
tween 25 - 89 MPH (40 - 144 km/h) without
keeping your foot on the accelerator pedal.
To turn on the cruise control,push the main
switch. The CRUISE indicator light in the instru-
ment panel comes on.
To set cruising speed,accelerate the vehicle to
the desired speed, push the SET/COAST switch
and release it. The SET indicator light in the
instrument panel comes on. Take your foot off the
accelerator pedal. Your vehicle maintains the set
speed.
cTo pass another vehicle,depress the ac-
celerator pedal. When you release the
pedal, the vehicle returns to the previously
set speed.
cThe vehicle may not maintain the set speed
when going up or down steep hills. If this
happens, drive without the cruise control.

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.
