cFuel may be under pressure. Turn the
cap a third turn, and wait for any “hiss-
ing” sound to stop to prevent fuel from
spraying out and possibly causing per-
sonal injury. Then remove the cap.
cDo not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
cUse only an original equipment type
fuel filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause the
malfunction indicator lamp to come on.
cNever pour fuel into the throttle body to
attempt to start your vehicle.cDo not fill a portable fuel container on a
truck bed liner, rubber truck bed mad,
or other insulating material. Static elec-
tricity can cause an explosion of flam-
mable liquid, vapor or gas in any vehicle
or trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices when
filling.
– Keep the pump nozzle in contact
with the container while you are fill-
ing it.
– Use only approved portable fuel con-
tainers for flammable liquid.
CAUTION
cIf fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.cTighten until the fuel filler cap clicks.
Failure to tighten the fuel filler cap
properly may cause the
mal-
function indicator lamp (MIL) to illumi-
nate. If the
lamp illuminates be-
cause the fuel filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle.
The
lamp should turn off after a
few driving trips. If the
lamp
does not turn off after a few driving
trips, have the vehicle inspected by a
NISSAN dealer.
cFor additional information, see the
“Malfunction indicator lamp (MIL)” in
the “Instruments and Controls” section
earlier in this manual.

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

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.
LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)
The low tire pressure warning system monitors
tire pressure of all tires (except the spare tire) .
The low tire pressure warning system will activate
only when the vehicle is driven at speeds above
20 MPH (32 km/h) . Also, this system may not
detect a sudden drop in tire pressure (for ex-
ample a flat tire while driving) .Frequently check the tire pressure and adjust
pressure of each tire properly.
Flat tire warning
If the vehicle is being driven with very low tire
pressure (lower than 27 psi, 190 kPa) , the low
tire pressure warning light comes on and the
chime sounds for about 10 seconds.
For additional information regarding the above
warning, see “Warning/indicator lights and au-
dible reminders” in the “Instruments and con-
trols” section.
WARNING
cIf the low tire pressure warning light
comes on while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Serious vehicle
damage could occur and may lead to an
accident and could result in serious
personal injury. Check the tire pressure
for all four tires and adjust the pressure
to the COLD tire pressure shown on the
tire placard. If you have a flat tire, re-
place it with a spare tire as soon as
possible. (See “Flat tire” in the “In case
of emergency” section for changing a
flat tire.)
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated and the low tire pressure
warning system will not function. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cDo not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
