*1:IThe transfer 4LO position indicator light
may blink. Stop the vehicle. Be sure to
shift the 4WD shift switch after the auto-
matic transmission lever has been
shifted to the N position. If the indicator
light keeps blinking after the 4WD shift
procedure in the previous page, drive
slowly without abrupt maneuvers for a
while. Then the light will turn on or off.
IAvoid making a turn or abrupt starts
while shifting to 4LO. Otherwise gears
may grind, damaging the drive system.
*2: Make sure the transfer 4LO position indica-
tor light turns on when you shift the 4WD
shift switch to 4LO.
The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of
drive modes available, AUTO, 2WD, 4H and
4LO.
The 4WD shift switch electronically controls
the transfer case operation. Rotate the switch
to move between each mode, 2WD, AUTO, 4H
and 4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and the
automatic transmission selector lever is in
the N position when changing into or out of
4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make
sure that the 4WD shift indicator light is
on and the ATP warning light goes off.
Otherwise, the vehicle could unexpect-
edly move even if the automatic trans-
mission is in the P position.
CAUTION
INever shift the 4WD shift switch be-
tween 4LO and 4H while driving.
IThe 4H position provides greater
power and traction. Avoid excessive
speed, as it will cause loss of trac-
tion. Speed over 50 MPH (80 km/h) in
4H is not recommend.
IThe 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 30 MPH
(50 km/h).IWhen driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or revers-
ing.
IDo not shift the 4WD shift switch
(between 2WD, AUTO and 4H) while
driving on steep downhill grades. Use
the engine brake.
IDo not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with
the rear wheels spinning.
IDo not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surfaces in 4H or 4LO
may cause unnecessary noise and
tire wear. We recommend driving in
the 2WD or AUTO position under
these conditions.
IVehicles equipped with a limited slip
differential (LSD) have improved driv-
ing performance on rough roads.
They have increased traction perfor-
mance, so when making a turn

clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
IIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possibly
degraded vehicle handling character-
istics and/or interference with the
brake discs. Such interference can
lead to decreased braking efficiency
and/or early brake pad wear.
IDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
IThe use of retread tire is not rec-
ommended.
Four wheel drive models
CAUTION
Always use tires of the same size, brand,
construction (bias, bias-belted or ra-
dial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the same size, brand, construction and
tread pattern. The tire pressure and wheel
alignment should also be checked and cor-
rected as necessary. Contact your NISSAN
dealer.Wheel balanceUnbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore, they
should be balanced as required.
Wheel balance service should be performedwith the wheels off the vehicle. Spin balancing
the rear wheels on the vehicle could lead to
transmission damage.
Care of wheelsIWash the wheels when washing the vehicle
to maintain their appearance.
IClean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
IDo not use abrasive cleaners when wash-
ing the wheels.
IInspect wheel rims regularly for dents or
corrosion. This may cause loss of pressure
or damage the tire bead.
INISSAN recommends that the road wheels
be waxed to protect against road salt in
areas where it is used during winter.TEMPORARY USE ONLY spare tire
(if so equipped)U.S. only. Canadian vehicles are equipped
with a full size spare tire.
Observe the following precautions if the TEM-
PORARY USE ONLY spare tire must be used,
otherwise your vehicle could be damaged or
involved in an accident.

AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONSThe air conditioning system in this NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
Nissan A/C System Oil Type S or the exact
equivalents.
CAUTION
The use of any other refrigerants or
lubricants will cause severe damage to
the air conditioning system and will re-
quire the replacement of all air condi-
tioning system components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle will not harm the earth's
ozone layer. Although this refrigerant does not
affect the earth's atmosphere, certain govern-
mental regulations require the recovery and
