tion frequently.
Lights*:Clean the headlights on a regular
basis. Make sure that the headlights, stop
lights, tail lights, turn signal lights, and
other lights are all operating properly and
installed securely. Also check headlight
aim.
Road wheel nuts (lug nuts)*: When
checking the tires, make sure no wheel
nuts are missing, and check for any loose
wheel nuts. Tighten if necessary.
Tire rotation*: Tires should be rotated
every 5,000 miles (8,000 km).
Tires*: Check the pressure with a gauge
often and always prior to long distance
trips. If necessary, adjust the pressure in
all tires, including the spare, to the
pressure specified. Check carefully for
damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the
TPMS transmitter grommet seal, valve
core and cap when the tires are replaced
due to wear or age.
Wheel alignment and balance: If the
vehicle should pull to either side while
driving on a straight and level road, or if
you detect uneven or abnormal tire wear,
there may be a need for wheel alignment.
If the steering wheel or seat vibrates at normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Informa-
tion” (US) or “Tire Safety Information”
(Canada) in the NISSAN Warranty Infor-
mation Booklet.
Windshield:
Clean the windshield on a
regular basis. Check the windshield at
least every six months for cracks or other
damage. Have a damaged windshield
repaired by a qualified repair facility.
Windshield wiper blades*: Check for
cracks or wear if they do not wipe
properly.
Inside the vehicle
The maintenance items listed here should
be checked on a regular basis, such as
when performing scheduled mainte-
nance, cleaning the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the
pedal does not catch or require uneven
effort. Keep the floor mat away from the
pedal.
Automatic transmission P (Park) me-
chanism: On a fairly steep hill, check that
your vehicle is held securely with the shift
lever in the P (Park) position without
applying any brakes. Brake pedal:
Check the pedal for smooth
operation. If the brake pedal suddenly
goes down further than normal, the pedal
feels spongy or the vehicle seems to take
longer to stop, have your vehicle checked
immediately. It is recommended you visit
a NISSAN dealer for this service. Keep the
floor mat away from the pedal.
Brakes: Check that the brakes do not pull
the vehicle to one side when applied.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with
only the parking brake applied. If the
parking brake needs adjusted, it is re-
commended you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position.
Check that the head restraints move up
and down smoothly and that the locks (if
so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, an-
chors, adjuster and retractors) operate
properly and smoothly, and are installed
securely. Check the belt webbing for cuts,
fraying, wear or damage.

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
manufacturer 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 sur-face. With the ignition switch in the ON
position and the doors closed, allow
the vehicle to stand for several min-
utes 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 adjust the hitch equalizers so that the
front bumper height is within 0 - .5
inches (0 - 13 mm) of the reference
height measured in step 2. The rear
bumper should be no higher than the
reference height measured in step 2.
WARNING
Properly adjust the weight distribut-
ing hitch so the rear of the bumper is
no higher than the measured refer-
ence height when the trailer is at-
tached. If the rear bumper is higher
than the measured reference height
when loaded, the vehicle may handle
unpredictably which could cause a
loss of vehicle control and cause
serious personal injury or property
damage.
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 instruc-
tions provided by the manufacturer for
installing and using the sway control
device.

trailer lights while using the ve-
hicle tail light, stoplight and turn
signal circuits as a signal source.
The module/converter must draw
no more than 15 milliamps from
the stop and tail lamp circuits.
Using a module/converter that
exceeds these power require-
ments may damage the vehicle’s
electrical system. See a reputable
trailer retailer to obtain the prop-
er equipment and to have it
installed.
. Do not connect electrical devices
that draw more than 40 amps to
the vehicle. The fusible link may
melt.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, contact a NISSAN
dealer or reputable trailer retailer.
Trailer brakes
When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used. However, most
states require a separate braking system
on trailers with a loaded weight above a
specific amount. Make sure the trailer
meets the local regulations and the
regulations where you plan to tow. Several types of braking systems are
available.
Surge Brakes -
The surge brake actuator
is mounted on the trailer tongue with a
hydraulic line running to each trailer
wheel. Surge brakes are activated by the
trailer pushing against the hitch ball
when the tow vehicle is braking. Hydraulic
surge brakes are common on rental
trailers and some boat trailers. In this
type of system, there is no hydraulic or
electric connection for brake operation
between the tow vehicle and the trailer.
Electric Trailer Brakes - Electric braking
systems are activated by an electronic
signal sent from a trailer brake controller
(special brake sensing module).
Have a professional supplier of towing
equipment make sure the trailer brakes
are properly installed and demonstrate
proper brake function testing.WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
. Be certain your vehicle maintains a
level position when a loaded or un-
loaded 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 condition.
. Always secure items in the trailer to
prevent load shift 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,
vehicle tire pressure, trailer light op-
eration, and trailer wheel lug nuts
every time you attach a trailer to the
vehicle.
. Be certain your rearview mirrors con-
form 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
vehicle and trailer so the required
clearance is known.

Trailer towing tips
In order to gain skill and an understand-
ing 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.
.Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a
pin or lock to prevent the coupler from
inadvertently becoming unlatched.
. Avoid abrupt starts, acceleration or
stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moder-
ate speed. Some states or provinces
have specific speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
. 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 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 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 absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Four-Wheel Drive (4WD) models:
Make sure that the 4WD shift switch is
engaged in the AUTO, 4HI or 4LO
position and the Automatic Transmis-
sion (AT) park warning light is turned
off.
7. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal. 2. Start the engine.
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.
. 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 shift to a lower gear.
Avoid long or repeated use of the
brakes when descending a hill, as this
reduces their effectiveness and could
cause overheating. Shifting to a lower
gear instead provides “engine braking”
and reduces the need to brake as
frequently.
. If the engine coolant temperature
rises to a high temperature, see “If
your vehicle overheats” (P.6-14).
. Trailer towing requires more fuel than
normal circumstances.
. Avoid towing a trailer for your vehicle’s
first 500 miles (800 km).
. Have your vehicle serviced more often
than at intervals specified in the
recommended maintenance schedule
shown in the "9. Maintenance and

schedules" section.
. 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
being passed by larger vehicles, be
prepared 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 combina-
tion will help stabilize the vehicle.
.Do not correct trailer sway bysteering 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 balanced as described earlier in this
section.
. Be careful when passing other vehi-
cles. 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.
. Use the Tow mode or downshift the
transmission to a lower gear for en-
gine 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, result-
ing in reduced braking efficiency.
. Increase your following distance to
allow for greater stopping distances
while towing a trailer. Anticipate stops
and brake gradually.
. NISSAN recommends that the cruise
control not be used while towing a
trailer.
. While towing a trailer, do not use the
following systems (if so equipped):
— the Lane Departure Warning (LDW)
system
— the Intelligent Lane Intervention (I- LI) system
— the Blind Spot Warning (BSW) sys- tem
— the Intelligent Blind Spot Interven- tion (I-BSI) system — the Intelligent Back-up Intervention
(I-BI) system
— the Intelligent Cruise Control (ICC) system
— the Intelligent Distance Control (I- DC) system
— the Automatic Emergency Braking (AEB) system
— the Intelligent Forward Collision Warning (I-FCW) system
. Some states or provinces have speci-
fic regulations and speed limits for
vehicles that are towing trailers. Obey
the local speed limits.
. Check your hitch, trailer wiring har-
ness connections, and trailer wheel
lug nuts after 50 miles (80 km) of
travel and at every break.
. When launching a boat, do not allow
the water level to go over the exhaust
tail pipe or rear bumper.
. Make sure you disconnect the trailer
lights (if so equipped) before backing
the trailer into the water or the trailer
lights may burn out.
When towing a trailer, the transmission
fluid should be changed more fre-
quently. For additional information,
see the "9. Maintenance and schedules"
section.
