The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system.
Proper brake inspection intervals should
be followed.For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.
BRAKE BOOSTER
Check the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) remains
the same from one pedal application to the
next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a little.
3. With the brake pedal depressed, stop the
engine. Keep the pedal depressed for about
30 seconds. The pedal height should not
change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.Two types of fuses are used. Type A is used in the
fuse boxes in the engine compartment. Type B is
used in the passenger compartment fuse box.
Type A fuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type A fuses can be installed in the engine com-
partment and passenger compartment fuse
boxes.

If a type A fuse is used to replace a type B fuse,
the type A fuse will not be level with the fuse
pocket as shown in the illustration. This will not
affect the performance of the fuse. Make sure the
fuse is installed in the fuse box securely.
Type B fuses cannot be installed in the under-
hood fuse boxes. Only use type A fuses in the
underhood fuse boxes.ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not come on,
check for an open fuse.
1. Be sure the ignition switch and the headlight
switch are OFF.
2. Open the engine hood.3. Remove the fuse box cover by pushing the
tab and lifting the cover up.
4. Remove the fuse with the fuse puller. The
fuse puller is located in the center of the fuse
block in the passenger compartment.

Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
CAUTION
cYour vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty.
cE-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline.
cU.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.
FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so equipped)
Your vehicle is designed to use (E-85) Fuel Etha-
nol, “Regular” unleaded regular gasoline or any
percentage of the two fuels combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a small,
square, orange and black label with the
common abbreviation or the appropriate
percentage for that region.
CAUTION
Use of other fuels such as Fuel Methanol
may cause powertrain damage or a loss of
vehicle performance.
General information
This information is for Flexible Fuel vehicles (FFV)
only. FFV vehicles can be identified by the fuel
filler door label that states Ethanol (E-85) or
Unleaded Gasoline Only. This section only cov-
ers those subjects that are unique to Flexible Fuel
vehicles.
CAUTION
Only vehicles with the E-85 filler door la-
bel can operate on E-85. Fuel system or
other damage can occur if E-85 is used in
vehicles that are not designed to run on
E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel etha-
nol and 15% unleaded gasoline.

4. Peel off the tape and connect the jumper
harness to the connector
s2.
5. Release the parking brake.
6. Install the aftermarket electric trailer brake
controller according to the manufacturer’s
instructions.
Pre-towing tips
cBe 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 possiblecauses of either condition.
cAlways secure items in the trailer to prevent
load shift while driving.
cLoad the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.
cCheck 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.
cBe certain your rearview mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding 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.
cAlways secure items in the trailer to prevent
load shift while driving.
cAvoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.cAlways drive your vehicle at a moderate
speed.
cWhen 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.
cAlways block the wheels on both vehicle and
trailer when parking. Parking on a slope is
not recommended; however, if you must do
so, first block the wheels and apply the park-
ing brake, and then move the transmission
shift selector lever into the P (Park) position.
If you move the shift selector lever to the P
(Park) position before blocking the wheels
and applying the parking brake, transmission
damage could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading and/or overheating. However, for
long steep grades, do not stay in 1st gear
when driving above 35 MPH (56 km/h) or
2nd gear when driving above 58 MPH (93
km/h) .

cIf the engine coolant rises to an extremely
high temperature when the air conditioner
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
cTrailer towing requires more fuel than normal
circumstances.
cAvoid towing a trailer for your vehicle’s first
500 miles (805 km) .
cFor the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
cHave your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
cWhen 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.
cCrosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmlygrip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help sta-
bilize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
cTo maintain engine braking efficiency and
electrical charging performance, do not use
overdrive.
cAvoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
cIncrease your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually
cDo not use cruise control while towing a
trailer.
cSome states or provinces have specific
speed limits for vehicles that are towing trail-
ers. Obey the local speed limits.
cCheck your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50miles (80 km) of travel and at every break.
cWhen stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
Tow mode
Tow mode should be used when pulling a heavy
trailer or hauling a heavy load. Press the tow
button to activate the tow mode. The tow indica-
tor in the instrument panel illuminates when the
tow mode is selected. Press the Tow button
again to turn the tow mode OFF. The Tow mode is
automatically cancelled when the key is turned
OFF.
The Tow mode does the following:
cReduces transmissions shifts when pulling a
trailer or hauling a load.
cProvides similar shift feel to driver when the
vehicle is towing.
The Tow mode should be used when the vehicle
and trailer weight is at least 75% of the vehicle’s

If you believe that your vehicle has a de-
fect which could cause a crash or could
cause injury or death, you should immedi-
ately inform the National Highway Traffic
Safety Administration (NHTSA) in addi-
tion to notifying NISSAN.
If NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and remedy
campaign. However, NHTSA cannot be-
come involved in individual problems be-
tween you, your dealer, or NISSAN.
To contact NHTSA, you may call the Auto
Safety Hotline toll-free at 1-888-327-
4236. You may also write to: NHTSA,
U.S. Department of Transportation,
Washington, D.C. 20590. You can also
obtain other information about motor ve-
hicle safety from the Hotline.
You may notify NISSAN by contacting our
Consumer Affairs Department, toll-free, at
1-800-NISSAN-1.Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready condi-
tion” 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 vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready” condition. Before taking the
I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Turn the ignition switch ON 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
9not ready9. If the MIL does not blink after 20
seconds, the I/M test condition is9ready.9If the
MIL indicates the vehicle is in a9not ready9con-
dition, drive the vehicle through the following
pattern to set the vehicle to the ready condition. If
you cannot or do not want to perform the driving
pattern, a NISSAN dealer can conduct it for you.WARNING
Always drive the vehicle in a safe and
prudent manner according to traffic con-
ditions and obey all traffic laws.
1. Start the engine when the engine coolant
temperature gauge needle points to C. Al-
low the engine to idle until the gauge needle
points between the C and H (normal oper-
ating temperature) .
2. Accelerate the vehicle to 55 MPH (88
km/h) , then quickly release the accelerator
pedal completely and keep it released for at
least 10 seconds.
3. Quickly depress the accelerator pedal for a
moment, then drive the vehicle at a speed of
53 - 60 MPH (86 - 96 km/h) for at least 9
minutes.
4. Stop the vehicle.
5. Accelerate the vehicle to 35 MPH (55 km/h)
and maintain the speed for 20 seconds.
6. Repeat steps 4 through 5 at least 10 times.
7. Accelerate the vehicle to 55 MPH (88 km/h)
and maintain the speed for at least 3 min-
utes.
