Do not try to open the top of the battery.
This battery is not equipped with remov-
able vent caps.
JUMP STARTING
If jump starting is necessary, see “Jump
starting” (P. 6-11). If the engine does not start
by jump starting, the battery may have to
be replaced. It is recommended that you
visit a NISSAN dealer for this service.
CAUTION
• Do not ground accessories directly to
the battery terminal. Doing so will
bypass the variable voltage control
system and the vehicle battery may
not charge completely.
• Use electrical accessories with the
engine running to avoid discharging
the vehicle battery.
NOTE:
If the battery is completely drained the
transmission will not manually shif t to
other positions.
Your vehicle is equipped with a variable
voltage control system. This system mea-
sures the amount of electrical discharge
from the battery and controls voltage gen-
erated by the generator.
The current sensor
OAis located near the
battery along the negative battery cable. If
you add electrical accessories to your ve-
hicle, be sure to ground them to a suitable
body ground such as the frame or engine
block area.

REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-
tipped
OAspark plugs as frequently as con-
ventional type spark plugs because they
last much longer. Follow the maintenance
log shown in the "Maintenance and sched-
ules" section of this manual. Do not service
iridium-tipped spark plugs by cleaning or
regapping.
• Always replace spark plugs with rec-
ommended or equivalent ones.

doors and engine hood operate properly.
Also ensure that all latches lock securely.
Lubricate hinges, latches, latch pins, rollers
and links if necessary. Make sure that the
secondary latch keeps the hood from
opening when the primary latch is
released.
When driving in areas using road salt or
other corrosive materials, check lubrica-
tion frequently.
Check that the gas stays or struts properly
and securely hold the hood, trunk, or rear
hatch fully open. If the hood, trunk, or rear
hatch is not held open, have the gas stays
or struts replaced.
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 in-
stalled securely. Also check headlight aim.
Road wheel nuts (lug nuts)*: When check-
ing 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 specified
interval shown in the maintenance
schedule.
Tires*: Check the pressure with a gauge
of ten 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)
tire pressure sensor: It is recommended
that you replace the tire pressure sensor
assembly when the tires are replaced due
to wear or age.
Wheel alignment and balance: If the ve-
hicle 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 steer-
ing wheel or seat vibrates at normal high-
way speeds, wheel balancing may be
needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet. Windshield:
Clean the windshield on a
regular basis. Check the windshield at least
every six months for cracks or other dam-
age. Have a damaged windshield repaired
by a qualified repair facility. It is recom-
mended that you have a damaged wind-
shield repaired by a NISSAN dealer, or a
NISSAN Certified Collision Center. To locate
a collision center in your area, refer to

diately. It is recommended that 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 adjustment, it is recom-
mended that 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 all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.

TOWING SAFETY
Trailer hitch
Your vehicle may be equipped with an op-
tional trailer tow package. The trailer tow
package includes a receiver-type frame
mounted hitch. This hitch is rated for the
maximum towing capacity of this vehicle
when the proper towing equipment is
used. Choose a proper ball mount and
hitch ball that is rated for the trailer to be
towed. Genuine NISSAN ball mounts and
hitch balls are available from a NISSAN
dealer.
If your vehicle is not equipped with the op-
tional trailer tow package, check the tow-
ing capacity of your bumper hitch or
receiver-type frame mounted hitch.
Choose a proper hitch for your vehicle and
trailer. A Genuine NISSAN trailer hitch is
available from a NISSAN dealer. Make sure
the trailer hitch is securely attached to the
vehicle to help avoid personal injury or
property damage due to sway caused by
crosswinds, rough road surfaces or pass-
ing trucks.
WARNING
Trailer hitch components have specific
weight ratings. Your vehicle may be ca-
pable of towing a trailer heavier than
the weight rating of the hitch compo-
nents. Never exceed the weight rating
of the hitch components. Doing so can
cause serious personal injury or prop-
erty 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 the 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. Addi-
tionally, the ball mount should be chosen
to keep the trailer tongue level with the
ground.
Technical and consumer information10-33

When towing a trailer load of 3,500 lbs.
(1587 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 regu-
lations 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 hy-
draulic 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 ve-
hicle and the trailer.
Electric Trailer Brakes -Electric braking
systems are activated by an electronic sig-
nal sent from a trailer brake controller (spe-
cial brake-sensing module). If electric trailer
brakes are used, see “Electric trailer brake
controller" (P. 10-37)..
Have a professional supplier of towing
equipment make sure the trailer brakes are properly installed and demonstrate proper
brake function testing.
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
controller.
Install the af termarket electric trailer brake
controller according to the manufacturer's
instructions.
Pre-towing tips
• Be certain your vehicle maintains a level
position 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
condition.
• 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.
Technical and consumer information10-37

• Avoid abrupt starts, acceleration or stops.
• Avoid sharp turns or lane changes.
• Always drive your vehicle at a moderatespeed.
• 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:
CAUTION
If you move the shif t 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. Af ter the wheel blocks are in place, slowly release the brake pedal until the
blocks absorb the vehicle load. 4. Apply the parking brake.
5. Shif t the transmission into P (Park).
6. Make sure the 4WD shif t indicator light (if
so equipped) indicates the transfer case
is in 4H, 4LO, or 2WD and that the ATP
light is off. If the 4WD shif t indicator light
is flashing, or the ATP light is ON, make
sure the transmission is in P (Park) and
turn the 4WD switch to 2WD or 4H. For
additional information, see “Automatic
transmission park warning light” (P. 2-13)
and “Using 4-wheel drive (4WD)” (P. 5-109).
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, see “If your vehicle
overheats” (P. 6-13).
• 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, see 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.
