OPENER OPERATION
The fuel filler opener lever is located on the out-
side of the driver’s seat
s1. To open the fuel filler
lid, pull the opener lever up. To lock, close the fuel
filler lid securely.
FUEL FILLER CAP
The fuel filler cap is a ratcheting type. Turn the
cap counterclockwise to remove. To tighten, turn
the cap clockwise until ratcheting clicks are
heard.
Put the fuel filler cap on the cap holder
s1while
refueling.
WARNING
cGasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
cFuel may be under pressure. Turn the
cap a third of a turn, and wait for any
“hissing” sound to stop to prevent fuel
from spraying out and possibly causing
personal 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.

WARNING
cOn hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or possi-
bly fatal injuries to people or animals.
Do not leave children or adults who
would normally require the support of
others in your vehicle. Unattended pets
should not be left alone either.
cClosely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children’s
access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
cDo not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death.cIf you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
cDo not run the engine in closed spaces
such as a garage.
cDo not park the vehicle with the engine
running for any extended length of time.
cKeep the trunk lid closed while driving,
otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the trunk lid
open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton (if so equipped) to off and the fan
control dial to 4 (high) to circulate
the air.
cIf electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the trunk lid or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle.
cThe exhaust system and body should be
inspected by a qualified mechanic
whenever:a. The vehicle is raised for service.
b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of
the exhaust system.
d. You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
cThe exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
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.

manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
3. Tire chains
WARNING
Tire chains/cables cannot be installed on
P215/45ZR17 size tires. Installation of the
tire chains/cables on P215/45ZR17 size
tires will cause damage to the vehicles. If
you plan to use tire chains/cables, you
should install P195/55R16 size tires on
your vehicle.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are of proper size for
the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions.Use only SAE Class “S”
chains.Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a winter
traction device (tire chains or cables) . The
minimum clearances are determined using
the factory equipped tire size. Other types
may damage your vehicle. Use chain ten-
sioners when recommended by the tire
chain manufacturer to ensure a tight fit.
Loose end links of the tire chain must besecured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Never install tire chains on spare tires. Do
not use tire chains on dry roads.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
cA scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
cA sturdy, flat board to be placed under the
jack to give it firm support.
cA shovel to dig the vehicle out of snowdrifts.
cExtra window washer fluid to refill the reser-
voir tank.

turning counterclockwise with the wheel nut
wrench.Do not remove the wheel nuts
until the tire is off the ground.2. Place the jack directly under the jack-up
point as illustrated so the top of the jack
contacts the vehicle at the jack-up point.

notches in the front or the rear as shown.
Also fit the groove of the jack head between
the notches as shown.
The jack should be used on firm and
level ground.
3. To lift the vehicle, securely hold the jack lever
and rod with both hands as shown. Carefully
