WARNING
• Overloading or improper loading of a
trailer and its cargo can adversely af-
fect vehicle handling, braking and
performance and may lead to
accidents.
• Do not tow a trailer when the TEMPO-
RARY FULL SIZE spare tire is installed.
CAUTION
• Do not tow a trailer or haul a heavy
load for the first 500 mile (805 km).
Your engine, axle or other parts could
be damaged.
• For the first 500 miles (805 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 ve-
hicle wear in at the heavier loads.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer places ad-
ditional loads on your vehicle's engine,
drive train, steering, braking and other sys-
tems.
A NISSAN Towing Guide (U.S. only) is available
on the website at www.nissanusa.com. This
guide includes information on trailer towing
capability and the special equipment re-
quired 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 in this section.
The total trailer load equals trailer weight
plus its cargo weight.
• When towing a trailer load of 3,500 lbs.
(1,587 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. Tow-
ing loads greater than these or using im-
proper towing equipment could adversely
affect vehicle handling, braking and perfor-
mance.
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 appropriate for level highway
driving may have to be reduced for low
traction situations (for example, on slippery
boat ramps).
LTI0161
TOWING A TRAILER
Technical and consumer information10-25

Bumper towing
The Genuine NISSAN step bumper has pro-
visions to install a trailer hitch ball and is
designed to tow trailers of a maximum
weight of 3,500 lbs. (1,588 kg).
To install a trailer hitch ball cut out the circle
in the center of the step bumper
OA, then
remove it to install the trailer hitch ball.
Weight carrying hitches
A weight carrying or “dead weight” ball
mount is one that is designed to carry the
whole amount of tongue weight and gross
weight directly on the ball mount and on
the receiver.
Weight distribution hitch
This type of hitch is also called a “load-
leveling” or “equalizing” hitch. A set of bars
attach to the ball mount and to the trailer
to distribute the tongue weight (hitch
weight) of your trailer. Many vehicles can't
carry the full tongue weight of a given
trailer, and need some of the tongue
weight transferred through the frame and
pushing down on the front wheels. This
gives stability to the tow vehicle.
A weight-distributing hitch system (Class
IV) is recommended if you plan to tow trail-
ers with a maximum weight over 5,000 lbs.
(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may
affect the operation of trailer surge
brakes. If you are considering use of a
weight-distributing hitch system with a
surge brake-equipped trailer, check with
the surge brake, hitch or trailer manufac-
turer to determine if and how this can be
done. Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface.
With the ignition on and the doors
closed, allow the vehicle to stand for sev-
eral minutes so that it can level.
2. Measure the height of a reference point on the front and rear bumpers at the
center of the vehicle.
3. Attach the trailer to the vehicle and ad- just the hitch equalizers so that the front
bumper height is within0-.5inches (0 –
13 mm) of the reference height mea-
sured in step 2. The rear bumper should
be no higher than the reference height
measured in step 2.

Sway control device
Sudden maneuvers, wind gusts, and buf-
feting caused by other vehicles can affect
trailer handling. Sway control devices may
be used to help control these affects. If you
choose to use one, contact a reputable
trailer hitch supplier to make sure the sway
control device will work with the vehicle,
hitch, trailer and the trailer's brake system.
Follow the instructions provided by the
manufacturer for installing and using the
sway control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 2,000 lbs.
(907 kg).
Class II hitch
Class II trailer hitch equipment (receiver,
ball mount and hitch ball) can be used to
tow trailers of a maximum weight of 3,500
lbs. (1,587 kg).
The Genuine NISSAN step bumper is con-
sidered a Class II ball mount.
Class III hitch
Class III trailer hitch equipment (receiver,
ball mount and hitch ball) can be used to
tow trailers of a maximum weight of 5,000
lbs. (2,268 kg).
Class IV hitch
Class IV trailer hitch equipment (receiver,
ball mount and hitch ball) can be used to
tow trailers of a maximum weight of 10,000
lbs. (4,535 kg). A weight distributing hitch
should be used to tow trailers that weigh
over 5,000 lbs. (2,268 kg).
Your vehicle may be equipped with Class IV
trailer hitch equipment that has a 10,000 lbs.
(4,535 kg) maximum weight rating, but your
vehicle is only capable of towing the maxi-
mum trailer weights shown in the “Towing
Load/Specification” chart in this section.
WARNING
• Do not use axle-mounted hitches.
• Do not modif y the vehicle exhaust
system, brake system, etc. to install a
trailer hitch.
• To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the receiver when not in use.
•
Regularly check that all trailer hitch
mounting bolts are securely mounted.
Tire pressures
• When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information label.
• Trailer tire condition, size, load rat- ing and proper inflation pressure
should be in accordance with the
trailer and tire manufacturer's
specifications.

Technical and consumer information

Electric trailer brake controller
Trailers equipped with electric brakes may
require the installation of an af termarket
trailer brake controller.
A Genuine NISSAN jumper harness is avail-
able that is specifically designed to be used
when installing an af termarket brake con-
troller.
Install the af termarket electric trailer brake
controller according to the manufacturer's
instructions.
Pre-towing tips
• Be certain your vehicle maintains a levelposition when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose-
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
• Always secure items in the trailer to pre- vent load shif t while driving.
• Keep the cargo load as low as possible in the trailer to keep the trailer center of
gravity low. • Load the trailer so approximately 60% of
the trailer load is in the front half and 40%
is in the back half. Also make sure the load
is balanced side to side.
• Check your hitch, trailer tire pressure, ve- hicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.
• Be certain your rearview mirrors conform to all federal, state or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
• Determine the overall height of the ve- hicle and trailer so the required clearance
is known.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering sta-
bility and braking performance will be
somewhat different than under normal
driving conditions.
• Always secure items in the trailer to pre-vent load shif t while driving.
• Lock the trailer hitch coupler with a pin or lock to prevent the coupler from inadver-
tently becoming unlatched. • Avoid abrupt starts, acceleration or stops.
• Avoid sharp turns or lane changes.
• Always drive your vehicle at a moderate
speed.
• When 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 back-
ing 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:

4. Apply the parking brake.
5. Shif t 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) (A/T) and turn
the 4WD switch to 2WD or 4H. For addi-
tional information, refer to “Automatic
transmission park warning light” in the
“Instruments and controls” section and
“Using 4-wheel drive (4WD)” in the “Start-
ing and driving” section of this manual.
7. Turn off the engine.
To drive away:
1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shif t 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.
• While going downhill, the weight of the trailer pushing on the tow vehicle may
decrease overall stability. Therefore, to
maintain adequate control, reduce your
speed and shif t to a lower gear. Avoid
long or repeated use of the brakes when
descending a hill, as this reduces their
effectiveness and could cause overheat-
ing. Shif ting to a lower gear instead pro-
vides “engine braking” and reduces the
need to brake as frequently.
• If the engine coolant temperature rises to a high temperature, refer to “If your ve-
hicle overheats” in the “In case of emer-
gency” section of this manual.
• Trailer towing requires more fuel than normal circumstances.
• Avoid towing a trailer for your vehicle's first 500 miles (805 km).
•
For the first 500 miles (805 km) that you do
tow, do not drive over 50 mph (80 km/h).
• Have your vehicle serviced more of ten than at intervals specified. For additional
information, refer to “Maintenance
Schedules” in the “Maintenance and
schedules” section of this manual. • When 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.
• Crosswinds and rough roads will ad- versely affect vehicle/trailer handling,
possibly causing vehicle sway. When be-
ing passed by larger vehicles, be pre-
pared for possible changes in crosswinds
that could affect vehicle 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 vehicle
– 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.
Technical and consumer information10-35

3. Try to rearrange the trailer load so it isbalanced as described in this section.
• Be careful when passing other vehicles. Passing while towing a trailer requires
considerably more distance than normal
passing. Remember, the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
• Downshif t 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.
• Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• NISSAN recommends that the cruise control not be used while towing a trailer.
• Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits. • Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
• When launching a boat, don't allow the water level to go over the exhaust tail
pipe or rear bumper.
• Make 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, refer
to the “Do-it-yourself ” section in this
manual.FLAT TOWING – 4WD WITH
AUTOMATIC TRANSMISSION
Towing a vehicle behind a recreational ve-
hicle, such as a motor home, is sometimes
called flat towing.

WARNING
A vehicle equipped with Four-Wheel
Drive (4WD) should never be tested us-
ing a two wheel dynamometer (such as
the dynamometers used by some
states for emissions testing), or similar
equipment. Make sure you inform the
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 transmis-
sion damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” 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 ve-
hicle. If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready ” condi-
tion. Before taking the I/M test, check the
vehicle's inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready ”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a ve-
hicle's systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
