CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the
tires every 7,500 miles (12,000 km).
For additional information on tire re-
placing procedures, refer to “Flat tire”
in the “In case of emergency” section
in this manual.
As soon as possible, tighten the
wheel nuts to the specified torque
with a torque wrench.Wheel nut tightening torque:
98 f t-lb (133 f t-lb)
The wheel nuts must be kept tight-
ened to specifications at all times.
It is recommended that wheel nuts
be tightened to specification at
each tire rotation interval.
WARNING
• Af ter rotating the tires, check
and adjust the tire pressure.
• Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).
• Do not include the spare tire in
the tire rotation.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

WARNING
• Tires should be periodically in-
spected for wear, cracking,
bulging or objects caught in
the tread. If excessive wear,
cracks, bulging or deep cuts
are found, the tire(s) should be
replaced.
• The original tires have built-in
tread wear indicators. When
the wear indicators are visible,
the tire(s) should be replaced.
• Tires degrade with age and
use. Have tires, including the
spare, over 6 years old checked
by a qualified technician be-
cause some tire damage may
not be obvious. Replace the
tires as necessary to prevent
tire failure and possible per-
sonal injury. •
Improper service of the spare
tire may result in serious per-
sonal injury. If it is necessary to
repair the spare tire, it is rec-
ommended that you visit a
NISSAN dealer for this service.
• For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carry-
ing capacity as originally equipped. For ad-
ditional information, refer to “Wheels and
tires” in the “Technical and consumer infor-
mation” section of this manual.

•If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section
of this manual.
• When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire
pressure warning light will flash for
approximately 1 minute. The light will
remain on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN
dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS. •
The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
• When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a
NISSAN dealer for ID registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.

WARNING
• It is extremely dangerous to
ride in a cargo area inside a ve-
hicle. In a collision, people rid-
ing in these areas are more
likely to be seriously injured or
killed.
• Do not allow people to ride in
any area of your vehicle that is
not equipped with seats and
seat belts.
• Be sure everyone in your ve-
hicle is in a seat and using a
seat belt properly.TERMS
It is important to familiarize yourself
with the following terms before
loading your vehicle:
• Curb Weight (actual weight of your vehicle) - vehicle weight including:
standard and optional equipment,
fluids, emergency tools, and spare
tire assembly. This weight does
not include passengers and cargo.
• GVW (Gross Vehicle Weight) - curb weight plus the combined weight
of passengers and cargo.
• GVWR (Gross Vehicle Weight Rat- ing) - maximum total combined
weight of the unloaded vehicle,
passengers, luggage, hitch, trailer
tongue load and any other op-
tional equipment. This information
is located on the F.M.V.S.S./
C.M.V.S.S. certification label.

INSTALLING FRONT LICENSE PLATE VEHICLE LOADING INFORMATION

WARNING
Do not install accessories over the gap
between the front and rear side chan-
nels. Doing this could affect the rear
structure in certain rear impacts, which
could result in serious injury.
LOADING TIPS
• The GVW must not exceed GVWR or GAWR as specified on the F.M.V.S.S./
C.M.V.S.S. certification label.
• Do not load the front and rear axle to the GAWR. Doing so will exceed
the GVWR.

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).

TOWING A TRAILER
Technical and consumer information10-25

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

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

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.
