WARNING
∙ Do not leave children or adults whowould normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding
or shif ting. Do not place cargo higher
than the seatbacks. In a sudden stop
or collision, unsecured cargo could
cause personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
∙ Do not breathe exhaust gases; theycontain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death. ∙ If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the ve-
hicle inspected immediately.
∙ Do not run the engine in closed spaces such as a garage.
∙ Do not park the vehicle with the en- gine running for any extended length
of time.
∙ Keep the rear vent windows, lif tgates, doors and trunk lids (if so equipped)
closed while driving, otherwise ex-
haust gases could be drawn into the
passenger compartment. If you must
drive with one of these open, follow
these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
∙ If electrical wiring or other cable con- nections must pass to a trailer
through the seal on the lif tgate or the
body, follow the manufacturer’s rec-
ommendation to prevent carbon
monoxide entry into the vehicle. ∙ The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system,
underbody, or rear of the vehicle.
∙ If a special body, camper, or other equipment is added for recreational
or other usage, follow the manufac-
turer’s recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas while
the engine is running even if the ve-
hicle is parked. Some recreational ve-
hicle appliances such as stoves, re-
frigerators, heaters, etc. may also
generate carbon monoxide.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

∙ Do not use the cruise control on slip-pery roads.
∙ Snow can trap dangerous exhaust gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F (-7°C)
or lower.
WARNING
∙ Do not use your engine block heaterwith an ungrounded electrical system
or a 2-pronged adapter. You can be
seriously injured by an electrical
shock if you use an ungrounded
connection.
∙ Disconnect and properly store the en- gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury. ∙ Use a heavy-duty 3-wire, 3-pronged
extension 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 least 2–4 hours, 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.

Failure to do so could result in damage
to the charging system and cause per-
sonal injury.1. If the booster battery is in another ve- hicle, position the 2 vehicles to bring
their batteries near each other.
Do not allow the two vehicles to
touch. 2. Apply the parking brake. Move the shif t
lever to P (Park). Switch off all unneces-
sary electrical systems (lights, heater,
air conditioner, etc.).
3. Ensure the vent caps are level and tight.
4. Connect the jumper cables in the se- quence illustrated (
A,B,C,D).
CAUTION
∙ Always connect positive () to posi-tive ( ) and negative () to body
ground (for example, strut mounting
bolt, engine lif t bracket, etc.) — not to

CAUTION
∙ Do not push start this vehicle. The3-way catalyst may be damaged.
∙ Automatic transmission models can- not be push-started or tow-started.
Attempting to do so may cause trans-
mission damage.
∙ For manual transmission models, never try to start the vehicle by tow-
ing it. When the engine starts, the for-
ward surge could cause the vehicle to
collide with the tow vehicle.
WARNING
∙ Do not continue to drive if your vehicleoverheats. 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.
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. 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) (automatic trans-
mission).
Do not stop the engine. 2. Turn off the air conditioner. Open all the
windows, move the heater or air condi-
tioner temperature control to maxi-
mum 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.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir
when the engine is cold. If the coolant
level is below the MIN level
B, add coolant
to the MAX level
A. If the reservoir is empty,
check the coolant level in the radiator
when the engine is cold. If there is insuffi-
cient coolant in the radiator, fill the radiator
with coolant up to the filler opening and
also add it to the reservoir up to the MAX
level
A. This vehicle contains Genuine NISSAN Long
Life Antifreeze/Coolant (blue). The life ex-
pectancy of the factory-fill coolant is
105,000 miles (168,000 km) or 7 years. Mixing
any other type of coolant or the use of
non-distilled water will reduce the life ex-
pectancy of the factory-fill coolant. For ad-
ditional information, refer to the "Mainte-
nance and schedules" section of this
manual.
If the cooling system frequently requires
coolant, it is recommended that you visit
a NISSAN dealer for this service.
For additional information on the location
of the engine coolant reservoir, refer to “En-
gine compartment check locations” in this
section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine
coolant. The service procedure can be
found in the NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine over-
heating.
WARNING
∙ To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
∙ Never remove the radiator or engine coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator.
∙ Avoid direct skin contact with used coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
∙ Keep coolant out of the reach of chil- dren and pets.
Engine coolant must be disposed of prop-
erly. Check your local regulations.
