cWhen driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on the
front wheels and the original tire used
on the rear wheels (drive wheels) . Use
tire chains only on the two rear original
tires.
cTire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster rate
than the standard tire. Replace the
spare tire as soon as the tread wear
indicators appear.
cDo not use the spare tire on other
vehicles.
cDo not use more than one spare tire at
the same time.
cDo not tow a trailer when the TEMPO-
RARY USE ONLY spare tire is installed.
CAUTION
cWith the spare tire installed the
transfer control lever must be in the 2H
position to prevent the transfer case
and differential gears from being
damaged.cDo not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire chains
will not fit properly and may cause dam-
age to the vehicle.
cBecause the TEMPORARY USE ONLY
spare tire is smaller than the original
tire, ground clearance is reduced. To
avoid damage to the vehicle, do not
drive over obstacles. Also, do not drive
the vehicle through an automatic car
wash since it may get caught.

Change intervals
The oil and oil filter change intervals for your
engine are based on the use of the specified
quality oils and filters. Using engine oil and filters
that are not of the specified quality, or exceeding
recommended oil and filter change intervals
could reduce engine life. Damage to the engine
caused by improper maintenance or use of incor-
rect oil and filter quality and/or viscosity is not
covered by the NISSAN new vehicle warranty.
Your engine was filled with a high-quality engine
oil when it was built. You do not have to change
the oil before the first recommended change
interval. Oil and filter change intervals depend
upon how you use your vehicle.
Operation under the following conditions may
require more frequent oil and filter changes:
crepeated short distance driving at cold outside
temperatures
cdriving in dusty conditions
cextensive idling
ctowing a trailer
RECOMMENDED SAE VISCOSITY
NUMBER
cSAE 5W-30 viscosity oil is preferred for all
temperatures. SAE 10W-30 or SAE
10W-40 viscosity oils may be used if the
ambient temperature is above 0°F (-18°C) .
AIR CONDITIONER SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioner system in your NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the lubricant,
NISSAN A/C system oil Type R or the exact
equivalents.
CAUTION
The use of any other refrigerant or lubri-
cant will cause severe damage to the air
conditioning system and will require the
replacement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
NISSAN vehicle does not harm the earth’s ozone
layer. Although this refrigerant does not affect the
earth’s atmosphere, certain government regula-
tions require the recovery and recycling of any
refrigerant during automotive air conditioner sys-
tem service. A NISSAN dealer has the trained
technicians and equipment needed to recover
and recycle your air conditioner system refriger-
ant.
Contact a NISSAN dealer when servicing your air
conditioner system.

Trailer towing tips
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.
cAlways secure items in the trailer to prevent
load shift while driving.
cAvoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate speed.
cAlways block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if your vehicle is equipped with an auto-
matic transmission, first block the wheels and
apply the parking brake, and then move the
transmission shift selector lever into the P
(Park) position. If you move the shift selector
lever to the P (Park) position before blocking
the wheels and applying the parking brake,
transmission damage could occur.
cWhen going down a hill, shift into a lower gear
and use the engine braking effect. When go-
ing up a long grade, downshift the transmis-
sion to a lower gear and reduce speed toreduce chances of engine overloading and/or
overheating. However, for long steep grades,
do not stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h) .
cIf the engine coolant rises to an extremely high
temperature when the air conditioner system
is on, turn off the air conditioner. Coolant heat
can be additionally vented by opening the win-
dows, switching the fan control to high and
setting the temperature control to the HOT
position.
cTrailer towing requires more fuel than normal
circumstances.
cAvoid towing a trailer for your vehicle’s first
500 miles (805 km) .
cHave your vehicle serviced more often than at
intervals specified in the recommended Main-
tenance Schedule in the “NISSAN Service
and Maintenance Guide”.
cWhen making a turn, your trailer wheels will be
closer to the inside of the turn than your vehicle
wheels. To compensate for this, make a larger
than normal turning radius during the turn.
cCrosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce vehicle
speed. This combination will help stabilize the
vehicle. Never increase speed.
cBe careful when passing other vehicles. Pass-
ing while towing a trailer requires considerably
more distance than normal passing. Remem-
ber, the length of the trailer must also pass the
other vehicle before you can safely change
lanes.
cTo maintain engine braking efficiency and
electrical charging performance, do not use
5th gear (manual transmission) or overdrive
(automatic transmission) .
cAvoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking effi-
ciency.
When towing a trailer, transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.

In Hawaii call 1-808-836-0888.Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” for an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition”’ when it
is driven through certain driving patterns. Usually,
the ready condition can be obtained by ordinary
usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready” condition. Before taking the
I/M test, drive the vehicle through the following
pattern to set the vehicle to the ready condition. If
you cannot or do not want to perform the driving
pattern, a NISSAN dealer can conduct it for you.
WARNING
Always drive the vehicle in a safe and
prudent manner according to traffic con-
ditions and obey all traffic laws.
1. Start the engine when the engine coolant
temperature gauge needle points to C. Al-
low the engine to idle until the gauge needle
points between the C and H (normal oper-
ating temperature) .
