Engine Malfunction Service now
This warning appears when there is a
problem with the engine. If this warning
appears, have the system checked. It is rec-
ommended that you visit a NISSAN dealer
for this service.
Engine hot Power reduced
This engine has a high fluid temperature
protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with
heavy loads, such as when towing a trailer),
engine power and, under some conditions,
vehicle speed will be decreased automati-
cally to reduce the chance of engine dam-
age. Vehicle speed can be controlled with
the accelerator pedal, but the engine and
vehicle speed may be reduced.
WARNING
When the high fluid temperature pro-
tection mode operation occurs, vehicle
speed may be gradually reduced. The
reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially
careful when driving. If necessary, pull
to the side of the road at a safe place
and allow the engine to return to nor-
mal operation; or have it repaired if
necessary.

some conditions, vehicle speed will be de-
creased automatically to reduce the
chance of transmission damage. Vehicle
speed can be controlled with the accelera-
tor pedal, but the engine and vehicle speed

When the Intelligent Key battery is dis-
charged or other strong radio wave
sources are present near the operating
location, the Intelligent Key operating
range becomes narrower, and the Intel-
ligent Key may not function properly.
The Remote Engine Start function can only
be used when the Intelligent Key is within
the specified operating range from the
vehicle.
The Remote Engine Start operating range
is approximately 197 f t (60 m) from the

flash and the tail lamps turn on. If the
vehicle is not within view press and hold
the
button for at least 2 seconds. The following events will occur when the
engine starts:
• The parking lights will turn on and remain
on as long as the engine is running.
• The doors will be locked and the climate control system may come on.
• The engine will continue to run for 10 min- utes. Repeat the steps to extend the time

performed. • The second 10 minutes will start immedi-
ately when the Remote Engine Start
function is performed again. For example,
if the engine has been running for 5 min-
utes, and 10 minutes are added, the en-
gine will run for a total of 15 minutes.
• Extending engine run time will count to- wards the two Remote Engine Start limit.
A maximum of two Remote Engine Starts,
or a single Remote Engine Start with an
extension, are allowed between ignition
cycles. The ignition switch must be cycled
to the ON position and then back to the

Pre-driving checks and adjustments3-21

1. Pull the hood lock release handleO1lo-
cated below the driver's side instrument
panel; the hood springs up slightly.
2. To open the hood, push the lever
O2un-
derneath the front of the hood upwards
with your fingertips as illustrated and
raise the hood.
3. Remove the support rod from the clamp
O3.
4. Insert the support rod
O4into the slot on
the passenger side of the hood.
5. When closing the hood, return the sup- port rod to its original position, lower the hood to approximately 12 in (30 cm)
above the latch and release it. This al-
lows proper engagement of the hood
latch.
WARNING
• Make sure the hood is completely
closed and latched before driving.
The vehicle should only ever be oper-
ated with the hood securely closed.
• If you see steam or smoke coming
from the engine compartment, to
avoid injury do not open the hood.
OPENER OPERATION
WARNING
• Do not drive with the trunk lid open.
This could allow dangerous exhaust
gases to be drawn into the vehicle.
For additional information, see “Ex-
haust gas (carbon monoxide)”
(P. 5-4).

OPENER OPERATION
The fuel-filler door release is located below
the instrument panel. To open the fuel-filler
door, pull the release. To lock, close the fuel-
filler door securely.
FUEL-FILLER CAP
WARNING
• Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seri-
ously injured if it is misused or mis-
handled. Always stop the engine and
do not smoke or allow open flames or
sparks near the vehicle when
refueling.
• Do not attempt to top off the fuel
tank af ter the fuel pump nozzle
shuts off automatically. Continued
refueling may cause fuel overflow,
resulting in fuel spray and possibly a
fire.
• Use only an original equipment type
fuel-filler cap as a replacement. It has
a built-in safety valve needed for
proper operation of the fuel system
and emission control system. An in-
correct cap can result in a serious
malfunction and possible injury. It
could also cause the
Malfunc-
tion Indicator Light (MIL) to come on.
• Never pour fuel into the throttle body
to attempt to start your vehicle. •
Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable
fuel containers:
– Always place the container on the
ground when filling.
– Do not use electronic devices
when filling.
– Keep the pump nozzle in contact
with the container while you are
filling it.
– Use only approved portable fuel
containers for flammable liquid.
CAUTION
• Do not use a fuel that contains more
than 15% ethanol in your vehicle. For
additional information, see “Fuel rec-
ommendation” (P. 10-4).

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Lock all doors.
• Position seat and adjust headrests/head restraints.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is pushed to the
ON position. For additional information,
see “Warning lights, indicator lights and
audible reminders” (P. 2-9). 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N (Neu-
tral). P (Park) is recommended.
The starter is designed not to operate
if the shif t lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the igni-
tion switch in any position.
• If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
• If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch to
the ON position to start cranking the
engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition
switch to the LOCK position. Af ter
