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 po- sition 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 device (which may have caused the in-
terference) separate from the regis-
tered 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, coolant, brake and clutch fluid (if so
equipped), 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 appear- ance and condition. Also check tires for
proper inflation.
∙ Lock all doors.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2.
Continuously Variable Transmission
model:
Move the shif t lever to P (Park) or N

5-14Starting and driving

∙ When driving on extremely inclinedsurfaces such as higher banked cor-
ners, the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate. Do not drive on these
types of roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or
ramp, the
indicator light may
flash or the
indicator light may
illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface.
∙ If wheels or tires other than the NISSAN recommended ones are used,
the VDC system may not operate
properly and the
indicator light
may flash or the
indicator light
may illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole, or use the re-
mote keyless entry key fob or the NISSAN
Intelligent Key®.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
refer to “Engine cooling system” in the “Do-
it-yourself ” section of this manual.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, refer to “Battery”
in the “Do-it-yourself ” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance
of these tires will be substantially re-
duced in snowy and icy conditions. If
you operate your vehicle on snowy or
icy roads, NISSAN recommends the use
of MUD & SNOW or ALL SEASON TIRES
on all four wheels. It is recommended
that you visit a NISSAN dealer for the tire
type, size, speed rating and availability
information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
COLD WEATHER DRIVING
Starting and driving5-77

∙ Use a heavy-duty 3-wire, 3-prongedextension cord rated for at least 10 A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure to
use the proper extension cord or a
grounded outlet can result in a fire or
electrical shock and cause serious
personal injury.
To use the engine block heater: 1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged exten-
sion cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on. 6. Before starting the engine, unplug and
properly store the cord to keep it away
from moving parts.
Starting and driving5-79

CAUTION
∙ Do not push start this vehicle. Thethree-way catalyst may be damaged.
∙ Continuously Variable Transmission (CVT) models and Manual Transmis-
sion (M/T) cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage
∙ For Manual Transmission (M/T) mod- els, never try to start the vehicle by
towing it. When the engine starts, the
forward surge could cause the vehicle
to collide with the tow vehicle. If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc., take the
following steps.
WARNING
∙ Do not continue to drive if your vehicle
overheats. Doing so could cause en-
gine damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
∙ Do not open the hood if steam is com- ing out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to N (Neutral) (manual trans-
mission) or to P (Park) (CVT).
Do not stop the engine.
2. Turn off the air conditioner (if so equipped). Open all the windows, move
the heater or air conditioner tempera-
ture control to maximum hot and fan
control to high speed. 3. Get out of the vehicle. Look and listen
for steam or coolant escaping from the
radiator before opening the hood. (If
steam or coolant is escaping, turn off
the engine.) Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or
the engine cooling fan. The engine cool-
ing fan can start at any time.
PUSH STARTING IF YOUR VEHICLE OVERHEATS

6. Af ter the engine cools down, check thecoolant level in the engine coolant res-
ervoir with the engine running. Add
coolant to the engine coolant reservoir
if necessary. Have your vehicle re-
paired. It is recommended that you visit
a NISSAN dealer for this service. When towing your vehicle, all State (Provin-
cial in Canada) and local regulations for
towing must be followed. Incorrect towing
equipment could damage your vehicle.
Towing instructions are available from a
NISSAN dealer. Local service operators are
generally familiar with the applicable laws
and procedures for towing. To assure
proper towing and to prevent accidental
damage to your vehicle, NISSAN recom-
mends having a service operator tow your
vehicle. It is advisable to have the service
operator carefully read the following pre-
cautions:
WARNING
∙ Never ride in a vehicle that is being
towed.
∙ Never get under your vehicle af ter it has been lif ted by a tow truck.
CAUTION
∙ When towing, make sure that thetransmission, axles, steering system
and powertrain are in working condi-
tion. If any of these conditions apply,
dollies or a flatbed tow truck must be
used.
∙ Always attach safety chains before towing.
For additional information, refer to “Flat
towing” in the “Technical and consumer in-
formation” section of this manual.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙ Park the vehicle on a level surface, ap-ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For manual trans-
mission models, move the shif t lever
to N (Neutral). For CVT models, move
the shif t lever to P (Park).
∙ Be sure the ignition switch is in the OFF or LOCK position when perform-
ing any parts replacement or repairs.
∙ If you must work with the engine run- ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙
Because the fuel lines on gasoline en-
gine models are under high pressure
even when the engine is off, it is recom-
mended that you visit a NISSAN dealer
for service of the fuel filter or fuel lines.
∙ Your vehicle is equipped with an auto- matic engine cooling fan. It may come
on at any time without warning, even
if the ignition key is in the OFF position
and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before work-
ing near the fan.
CAUTION
∙ Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ∙
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
∙ Never leave the engine or the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life
Antifreeze/Coolant (blue) and 50% water to
provide year-round antifreeze and coolant
protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Addi-
tional engine cooling system additives are
not necessary.
WARNING
∙ Never remove the radiator or coolantreservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. For additional informa-
tion on precautions, refer to “If your
vehicle overheats” found in the “In
case of emergency ” section of this
manual.
∙ The radiator is equipped with a pres- sure type radiator cap. To prevent en-
gine damage, use only a Genuine
NISSAN radiator cap.
CAUTION
∙ Never use any cooling system addi-tives such as radiator sealer. Additives
may clog the cooling system and
cause damage to the engine, trans-
mission and/or cooling system.
∙ When adding or replacing coolant, be sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze protection to -34° F (-37° C). The
use of other types of coolant solu-
tions other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent may damage the engine
cooling system. ∙ The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue),
including Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer
to the “Maintenance and schedules”
section of this manual.
