The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
cIf the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break-in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drum/rotors are replaced, in order to assure the
best brake 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.
WARNING
cEthanol vapors are extremely flam-
mable and could cause serious per-
sonal injury.
cNever have any smoking materials lit in
or near the vehicle when removing the
fuel filler cap or filling the tank.cDo not use E-85 as a cleaning agent and
never use it near an open flame.
Fuel requirements
Your vehicle will operate on both unleaded regu-
lar gasoline with an octane rating of at least
87 AKI (Anti-Knock Index) number (Research
octane number 91) , or E-85 fuel, or any mixture of
these two.
For the best starting and vehicle driveability re-
sults, do not continually switch between E-85
and unleaded regular gasoline. If you must switch
fuels, NISSAN recommends the following:
cdo not switch when the fuel gauge indicates
less than 1/4 full
cadd more than 5 gallons of fuel
coperate the vehicle immediately after refuel-
ing for a period of at least 5 minutes
NOTE:
When the ambient temperature is above
90°F (32°C) , you may experience hard start-
ing and rough idle following start up even if
the above recommendations are followed.
Starting
The characteristics of E-85 fuel make it unsuit-
able for use when ambient temperatures fall be-low 0°F (-18°C) . In the range of 0°F (-18°C) to
32°F (0°C) , you may experience an increase in
the time it takes for you engine to start, and a
deterioration in drivability (sags and/or hesita-
tions) until the engine is fully warmed up.
Fuel consumption
Because E-85 fuel contains less energy per gal-
lon than gasoline, you will experience an increase
in fuel consumption. You can expect your fuel
mileage to decrease by about 30% compared to
gasoline operation.
Replacement parts
Many components in your Flexible Fuel Vehicle
(FFV) are designed to be compatible with etha-
nol. Always be sure that your vehicle is serviced
with correct ethanol compatible parts.
CAUTION
Replacing fuel system components with
non-ethanol compatible components can
damage your vehicle and may also affect
the warranty coverage.
Maintenance
If you operate your vehicle using E-85 fuel, follow
the correct maintenance log shown in the
“NISSAN Service and Maintenance Guide”.
