9-2Maintenance and schedules
Some day-to-day and regular mainte-
nance is essential to maintain your vehi-
cle in good mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make
sure that the scheduled maintenance, as
well as general maintenance, is per-
formed.
As the vehicle owner, you are the only one
who can ensure that your vehicle receives
the proper maintenance. You are a vital
link in the maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those
items which should be checked during
normal day-to-day operation. They are
essential for proper vehicle operation. It is
your responsibility to perform these pro-
cedures regularly as prescribed.
Performing general maintenance checks
requires minimal mechanical skill and
only a few general automotive tools.
These checks or inspections can be done
by yourself, a qualified technician or, if you
prefer, a NISSAN dealer.
SCHEDULED MAINTENANCE
The maintenance items listed in this
section are required to be serviced at
regular intervals. However, under severe
driving conditions, additional or more
frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the

other corrosive materials, check lubrica-
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*: Rotate tires at the speci-
fied interval shown in the maintenance
schedule.
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. It is
recommended that you have a damaged
windshield repaired by a NISSAN dealer, or
a NISSAN Certified Collision Center. To
locate a collision center in your area, refer
to http://collision.nissanusa.com.
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.

To install the trailer hitch cover:
1. Insert the upper clips to the recesses
, and then push in the cover to its
original position.
2. Install the 2 clips
.
WARNING
Trailer hitch components have spe-
cific weight ratings. Your vehicle may
be capable of towing a trailer heavier
than the weight rating of the hitch
components. Never exceed the
weight rating of the hitch compo-
nents. Doing so can cause serious personal injury or property damage.
Hitch ball
Choose a hitch ball of the proper size and
weight rating for your trailer:
.
The required hitch ball size is stamped
on most trailer couplers. Most hitch
balls also have the size printed on top
of the ball.
. Choose the proper class hitch ball
based on the trailer weight.
. The diameter of the threaded shank of
the hitch ball must be matched to the
ball mount hole diameter. The hitch
ball shank should be no more than
1/16″ smaller than the hole in the ball
mount.
. The threaded shank of the hitch ball
must be long enough to be properly
secured to the ball mount. There
should be at least 2 threads showing
beyond the lock washer and nut.
Ball mount
The hitch ball is attached to the ball
mount and the ball mount is inserted into
the hitch receiver. Choose a proper class
ball mount based on the trailer weight.
Additionally, the ball mount should be
chosen to keep the trailer tongue level
with the ground.
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
cannot 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
trailers with a maximum weight over
5,000 lbs (2,267 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

10-32Technical and consumer information
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 andtrailer 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
(See “How to enable/disable the
LDW system” (P.5-28).)
— the Intelligent Lane Intervention (I- LI) system
(See “How to enable/disable the I-LI
system” (P.5-34).)
