AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your NISSAN
vehicle must be charged with the refriger-
ant HFC-134a (R-134a) and the oil, NISSAN
A/C system oil Type S or the exact equiva-
lents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replace-
ment 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.

When planning to drive your NISSAN ve-
hicle in another country,you should first find
out if the fuel available is suitable for your vehi-
cle’s engine.
Using fuel with an octane rating that is too low
may cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline. There-
fore, avoid taking your vehicle to areas where
appropriate fuel is not available.
When transferring the registration of your
vehicle to another country, state, province
or district,it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle emis-
sion control and safety standards vary according
to the country, state, province or district; there-
fore, vehicle specifications may differ.
When any vehicle is to be taken into an-
other country, state, province or district
and registered, its modifications, transpor-
tation, and registration are the responsibil-
ity of the user. NISSAN is not responsible
for any inconvenience that may result.

WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION
cDo not tow a trailer or haul a heavy load
for the first 500 miles (800 km) . Your
engine, axle or other parts could be
damaged.
cFor the first 500 miles (800 km) that you
tow a trailer, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other
parts of your vehicle wear in at the
heavier loads.
Your new vehicle was designed to be used pri-
marily to carry passengers and cargo. Remember
that towing a trailer places additional loads on
your vehicle’s engine, drive train, steering, brak-
ing and other systems.
A NISSAN Towing Guide (U.S. only) is available
on the website at www.nissanusa.com. This
guide includes information on trailer towing ca-
pability and the special equipment required for
proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the “Towing
Load/Specification” chart found later in this sec-
tion. The total trailer load equals trailer weight
plus its cargo weight.
cWhen towing a trailer load of 3,500 lbs.
(1587 kg) or more, trailers with a brake
system MUST be used.
The maximum Gross Combined Weight Rating
(GCWR) should not exceed the value specified
in the following “Towing Load/Specification”
chart.
The GCWR equals the combined weight of the
towing vehicle (including passengers and cargo)
plus the total trailer load. Towing loads greater
than these or using improper towing equipment
could adversely affect vehicle handling, braking
and performance.
The ability of your vehicle to tow a trailer is not
only related to the maximum trailer loads, but also
the places you plan to tow. Tow weights appro-
priate for level highway driving may have to be
reduced for low traction situations (for example,
on slippery boat ramps) .

Temperature conditions can also affect towing.
For example, towing a heavy trailer in high outside
temperatures on graded roads can affect engine
performance and cause overheating. The engine
protection mode, which helps reduce the chance
of engine damage, could activate and automati-
cally decrease engine power. Vehicle speed may
decrease under high load. Plan your trip carefully
to account for trailer and vehicle load, weather
and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
Pull to the side of the road to a safe area.
Allow the engine to cool and return to
normal operation. See “If your vehicle
overheats” in the “In case of emergency”
section of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by
NISSAN warranties.
Tongue load
When using a weight carrying or a weight distrib-
uting hitch, keep the tongue load between 10 -
15 percent of the total trailer load within the
maximum tongue load limits shown in the follow-
ing “Towing Load/Specification” chart. If the
tongue load becomes excessive, rearrange cargo
to allow for proper tongue load.
Maximum Gross Vehicle Weight
(GVW)/maximum Gross Axle Weight
(GAW)
The GVW of the towing vehicle must not exceed
the Gross Vehicle Weight Rating (GVWR)
shown on the F.M.V.S.S./C.M.V.S.S. certification
label. The GVW equals the combined weight of
the unloaded vehicle, passengers, luggage,
hitch, trailer tongue load and any other optional
equipment. In addition, front or rear GAW must
not exceed the Gross Axle Weight Rating
(GAWR) shown on the F.M.V.S.S./C.M.V.S.S.
certification label.

cAlways secure items in the trailer to prevent
load shift while driving.
cLock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadvert-
ently becoming unlatched.
cAvoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
cWhen backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.
Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
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.
1. Apply and hold the brake pedal.2. Have someone place blocks on the downhill
side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly
release the brake pedal until the blocks ab-
sorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Make sure the
indicator light (if so
equipped) indicates the transfer case is in
4H, 4L, or 2H and that the ATP light is off. If
the
indicator light is flashing, or the
ATP light is ON, make sure the transmission
is in P (Park) (AT) and turn the 4WD switch
to 2WD or 4H. See9Automatic transmission
park warning light9in the9Instruments and
controls9section and9Using four wheel
drive9in the9Starting and driving9section.
7. Turn off the engine.
To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are
clear from the blocks.6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading and/or overheating. However, for
long steep grades, do not stay in 1st gear
when driving above 35 MPH (56 km/h) or
2nd gear when driving above 58 MPH (93
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 windows, 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) .
cFor the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .

cHave your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice 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.
Do the following if the trailer begins to sway:
1. Take your foot off the accelerator pedal to
allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle
– Do not correct trailer sway by steering or
applying the brakes.
2. When the trailer sway stops, gently apply the
brakes and pull to the side of the road in a
safe area.3. Try to rearrange the trailer load so it is bal-
anced as described earlier in this section.
cBe careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
cDownshift the transmission to a lower gear
for engine braking when driving down steep
or long hills. This will help slow the vehicle
without applying the brakes.
cTo maintain engine braking efficiency and
electrical charging performance, do not use
overdrive.
cAvoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
cIncrease your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
cDo not use cruise control while towing a
trailer.cSome states or provinces have specific
regulations and speed limits for vehicles that
are towing trailers. Obey the local speed
limits.
cCheck your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
cWhen stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
cWhen launching a boat, don’t allow the wa-
ter level to go over the exhaust tail pipe or
rear bumper.
cMake sure you disconnect the trailer lights
before backing the trailer into the water or
the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
