5-116Starting and driving
7. Avoid idling..Shutting off your engine when safefor stops exceeding 30-60 seconds
saves fuel and reduces emissions.
8. Buy an automated pass for toll roads.
.Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and
avoid stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no morethan 30 seconds of idling at start-
up to effectively circulate the en-
gine oil before driving.
.Your vehicle will reach its ideal
operating temperature more
quickly while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, re-
sulting in reduced demand on your
A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire
wear and lowers fuel economy.
. Use the recommended viscosity en-
gine oil. (See “Engine oil and oil filter
recommendation” (P.10-5).)
WARNING
.Do not attempt to raise two
wheels off the ground and shift
the transmission to any drive or
reverse position with the engine
running. Doing so may result in
drivetrain damage or unexpected
vehicle movement which could
result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel
dynamometer or similar equip-
ment even if the other two
wheels are raised off the ground.
Make sure you inform test facility
personnel that your vehicle is
equipped with 4WD before it is
placed on a dynamometer. Using
the wrong test equipment may
result in drivetrain damage or
unexpected vehicle movement
which could result in serious ve-
hicle damage or personal injury.
INCREASING FUEL ECONOMYNISSAN ALL-MODE 4WD® (if so equipped)

5-120Starting and driving
The 4WD shift switch is used to select the
4WD mode depending on the driving
conditions. There are 3 types of drive
modes available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically con-
trols the transfer case operation. Rotate
the switch to move between each mode,
AUTO, 4H and 4L.
You must depress the 4WD shift switch
to select 4L, and the vehicle MUST be
stationary and the shift lever in the N
(Neutral) position when changing into
or out of 4L.
WARNING
.When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shift
indicator is on and the ATP warn-
ing light turns off. Otherwise, the
vehicle could unexpectedly move
even if the automatic transmis-
sion is in the P (Park) position.
. The 4LO and 4HI indicators must
stop blinking and the 4LO or 4HI
indicator must remain illumi-
nated or turn off before shifting
the transmission into gear. If the
shift lever is shifted from the N
(Neutral) position to any other gear while the 4LO and 4HI in-
dicators are blinking alternately,
the vehicle may move unexpect-
edly.
CAUTION
.
Never shift the 4WD shift switch
between 4L and 4H while driving.
. The 4HI position provides greater
traction. Avoid excessive speed,
as it will cause increased fuel
consumption and higher oil tem-
peratures, and could damage dri-
vetrain component. Speeds over
62 MPH (100 km/h) in 4HI is not
recommended.
. The 4LO position provides max-
imum traction. Avoid raising ve-
hicle speed excessively, as the
maximum speed is approxi-
mately 31 MPH (50 km/h).
. When driving straight, shift the
4WD shift switch to the AUTO or
4H position. Do not move the 4WD
shift switch when making a turn
or reversing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while
driving on steep downhill grades. Use the engine brake and low
automatic transmission gears
for engine braking.
. Do not operate the 4WD shift
switch (between AUTO and 4H)
with the rear wheels spinning.
. Do not drive on dry hard surface
roads in the 4HI or 4LO position.
Driving on dry hard surfaces in
4HI or 4LO may cause unneces-
sary noise and tire wear. NISSAN
recommends driving in the AUTO
position under these conditions.
. The 4WD transfer case may not
be shifted between 4HI and 4LO
at low ambient temperatures and
the 4LO and 4HI indicators may
blink even when the 4WD shift
switch is shifted. After driving for
a while you can change the 4WD
shift switch between 4H and 4L.
When driving on rough roads,
. Drive carefully according to the road
surface conditions.
When the vehicle is stuck,
. Place stones or wooden blocks under
the tires to free the vehicle.
. Set the 4WD shift switch to 4H or 4L.

5-122Starting and driving
.Never shift the 4WD shift switch
between 4L and 4H while driving.
. Engine idling speed is high while
warming up the engine. Be espe-
cially careful when starting or
driving on slippery surfaces with
the 4WD shift switch in AUTO.

4WD SHIFT INDICATOR
The 4WD shift indicator is displayed in the
vehicle information display.
The indicator should turn off within 1
second after placing the ignition switch
in the ON position.
While the engine is running, the 4WD shift
indicator will illuminate the position se-
lected by the 4WD shift switch. (See the
4WD shift procedure list shown in the
“NISSAN all-mode 4WD® system” (P.5-117).)
.The 4WD shift indicator may blink
while shifting from one drive mode
to the other. When the shifting is
completed, the 4WD shift indicator will come on. If the indicator does
not come on immediately, make
sure the area around the vehicle is
safe, and drive the vehicle straight,
accelerate or decelerate or move the
vehicle in reverse, then shift the 4WD
shift switch.
. If the 4WD warning light comes on, the
4WD shift indicator turns off.

8-2Do-it-yourself
When performing any inspection or main-
tenance work on your vehicle, always
take care to prevent serious accidental
injury to yourself or damage to the
vehicle. The following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
Move the shift lever to P (Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid
injury, always disconnect the ne-
gative battery cable before work-
ing near the fan. .
Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-34).)
You should be aware that incomplete or
improper servicing may result in operat-
ing difficulties or excessive emissions, and
MAINTENANCE PRECAUTIONS

could affect your warranty coverage.If in

1. Place a large drain pan under thedrain plug.
2. Remove the oil filler cap.
3. Remove the drain plug
with a
wrench and completely drain the oil.
CAUTION
Be careful not to burn yourself, as
the engine oil is hot.
.Waste oil must be disposed of properly.
.Check your local regulations.
4. (Perform steps 4 to 7 only when the engine oil filter change is needed.)
Loosen the oil filter
with an oil filter
wrench. Remove the oil filter by turn-
ing it by hand.
5. Wipe the engine oil filter mounting surface with a clean rag.
CAUTION
Be sure to remove any old rubber
gasket remaining on the mounting
surface of the engine. Failure to do
so could lead to engine damage.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten
additionally more than 2/3 turn.
Oil filter tightening torque:11 to 15 ft-lb
(15 to 21 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten
the drain plug with a wrench.
Drain plug tightening torque:22 to 29 ft-lb
(29 to 39 N·m) Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
CAUTION
The dipstick must be inserted in
place to prevent oil spillage from
the dipstick hole while filling the
engine with oil.
See “Capacities and recommended
fluids/lubricants” (P.10-2) for drain
and refill capacity. The drain and refill
capacity depends on the oil tempera-
ture and drain time. Use these speci-
fications for reference only. Always
use the dipstick to determine the
proper amount of oil in the engine.
10. Start the engine and check for leak- age around the drain plug and the oil
filter. Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level
with the dipstick. Add engine oil if
necessary.
