8. After starting your engine, carefully discon-nect the negative cable and then the positive
cable (
*4?*3?*2?*1).
9. Replace the vent caps (if so equipped) . Be sure to dispose of the cloth used to cover
the vent holes as it may be contaminated
with corrosive acid.
10. Put the battery cover on. Do not attempt to start the engine by pushing.CAUTION
.
Automatic transmission models
cannot be push-started or tow-
started. Attempting to do so may
cause transmission damage.
. Three way catalyst equipped models
should not be started by pushing
since the three way catalyst may be
damaged.
. 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.
CAUTION
. Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle
fire.
. To avoid the danger of being
scalded, never remove the radiator
cap or coolant reservoir cap while
the engine is still hot. When the
radiator cap or coolant reservoir cap
is removed, pressurized hot water
will spurt out, possibly causing
serious injury.
. Do not open the hood if steam is
coming 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, apply the parking brake and move the shift lever to
the P (Park) position.
Do not stop the engine.
2. Turn off the heater and air conditioner. Open all the windows, move the heater or air

conditioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climbing a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. 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 further until no steam
or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. 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 coolant is leaking 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
cooling fan can start at any time.
7. After the engine cools down, check the coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired. It is recommended you visit a
NISSAN dealer for this service.
In case of emergency6-15

8-4Do-it-yourself
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 anti-freeze
and coolant protection. The antifreeze solution
contains rust and corrosion inhibitors. Additional
engine cooling system additives are not neces-
sary.
WARNING
.Never remove the radiator or cool-
ant reservoir 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.
See precautions in “If your vehicle
overheats” (P.6-14) .
. The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system ad-
ditives such as radiator sealer. Ad-
ditives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling sys-
tem.
. When adding or replacing coolant,
be sure to use only Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent. Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) is pre-diluted to provide
antifreeze protection to í348 F
(í378C) . If additional freeze protec-
tion is needed due to weather where
you operate your vehicle, add Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) concentrate follow-
ing the directions on the container.
If an equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain minimum
antifreeze protection to í348 F
(í378C) . The use of other types of
coolant solutions other than Genu- ine 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/Cool-
ant (blue) , including Genuine
NISSAN Long Life Antifreeze/Cool-
ant (green) , or the use of non-
distilled water will reduce the life
expectancy of the factory-fill cool-
ant. Refer to the “9. Maintenance
and schedules” section of this man-
ual for more details.

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
MIN
*2, open the reservoir tank cap and add
coolant up to the MAX
*1level. If the reservoir
tank is empty, check the coolant level in the
radiator when the engine is cold. If there is
insufficient coolant in the radiator, fill the radiator
with coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level
*1.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant
frequently, have it checked. It is recom-
mended you visit a NISSAN dealer for this service.
CHANGING ENGINE COOLANT
It is recommended that major cooling system
repairs be performed by a NISSAN dealer. The
service procedures can be found in the appro-
priate NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
.
To avoid the danger of being
scalded, never change the coolant
when the engine is hot.
. Never remove the radiator cap or
coolant reservoir cap when the en-
gine is hot. Serious burns could be
caused by high pressure fluid es-
caping 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 reach of chil-
dren and pets.
Engine coolant must be disposed of properly. Check your local regulations.

.E-15 fuel contains more than 10%
oxygenate. E-15 fuel will adversely
affect the emission control devices
and systems of the vehicle and should
not be used. Damage caused by such
fuel is not covered by the NISSAN new
vehicle limited warranty.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol) . It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in NISSAN
vehicles.
If any undesirable driveability problems such as
engine stalling or hard hot starting are experi-
enced after using oxygenate-blend fuels, im-
mediately change to a non-oxygenate fuel or a
fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.E-15 fuel
E-15 fuel is a mixture of approximately 15% fuel
ethanol and 85% unleaded gasoline. E-15 can
only be used in vehicles designed to run on E-
15 fuel. Do not use E-15 in your vehicle. U.S.
government regulations require fuel ethanol
dispensing pumps to be identified with small,
square, orange and black label with the common
abbreviation or the appropriate percentage for
that region.
E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV) . Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage for
that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manganese
tricarbonyl, is an octane boosting additive.
NISSAN does not recommend the use of fuel
containing MMT. Such fuel may adversely affect
vehicle performance, including the emissions
control system. Note that while some fuel pumps
label MMT content, not all do, so you may have to consult your gasoline retailer for more details.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (Example: fuel injector
cleaner, octane booster, intake valve deposit
removers, etc.) which are sold commercially.
Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock.
(Spark knock is a metallic rapping noise.)
If severe, 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, it is recommended you 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 will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
Technical and consumer information10-5

10-18Technical and consumer information
outside temperatures on graded roads can
affect engine performance and cause overheat-
ing. The transmission high fluid temperature and
engine protection mode, which helps reduce the
chance of transmission and engine damage,
could activate and automatically decrease en-
gine power. Vehicle speed may decrease under
high load. Plan your trip carefully to account for
trailer and vehicle load, weather and road
conditions.
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The
reduced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area.
Allow the engine to cool and return to
normal operation. See“If your vehicle
overheats” (P.6-14) .
CAUTION
Vehicle damage resulting from impro-
per towing procedures is not covered by
NISSAN warranties.
STI0542
Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load between
10 to 15% of the total trailer load or use the
trailer tongue load specified by the trailer
manufacturer. The tongue load must be within
the maximum tongue load limits shown in the
following “Towing Load/Specification” chart. If
the tongue load becomes excessive, rearrange
cargo to allow for proper tongue load.

CAUTION
If you move the shift lever to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until the blocks
absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park) .
6. Four-Wheel Drive (4WD) models:
Make sure that the 4WD shift switch is
engaged in the AUTO, 4HI or 4LO position
and the Automatic Transmission (AT) park
warning light is turned off.
7. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift the transmission into gear. 4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are
clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks.
. While going downhill, the weight of the
trailer pushing on the tow vehicle may
decrease overall stability. Therefore, to
maintain adequate control, reduce your
speed and shift to a lower gear. Avoid long
or repeated use of the brakes when
descending a hill, as this reduces their
effectiveness and could cause overheating.
Shifting to a lower gear instead provides
“engine braking” and reduces the need to
brake as frequently.
. If the engine coolant temperature rises to a
high temperature, see “If your vehicle over-
heats” (P.6-14) .
. Trailer towing requires more fuel than normal
circumstances.
. Avoid towing a trailer for your vehicle’s first
500 miles (800 km).
. Have your vehicle serviced more often than
at intervals specified in the recommended
maintenance schedule shown in the "9.
Maintenance and schedules" section. .
When 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.
. Crosswinds 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
vehicle handling.
Do the following if the trailer begins to sway:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the
vehicle.
.Do not correct trailer sway by steering orapplying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of the road in
a safe area.
3. Try to rearrange the trailer load so it is balanced as described earlier in this section.
. Be careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the trailer
must also pass the other vehicle before you
Technical and consumer information10-27

can safely change lanes.
. Use the Tow mode or downshift the
transmission to a lower gear for engine
braking when driving down steep or long
hills. This will help slow the vehicle without
applying the brakes.
. Avoid holding the brake pedal down too
long or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
. Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
. NISSAN recommends that the cruise con-
trol not be used while towing a trailer.
. While towing a trailer, do not use the
following systems (if so equipped):
— the Lane Departure Warning (LDW)
system
— the Lane Departure Prevention (LDP) system
— the Blind Spot Warning (BSW) system
— the Blind Spot Intervention
Š(BSI) sys-
tem
— the Back-up Collision Intervention (BCI) system
— the Intelligent Cruise Control (ICC) system — the Distance Control Assist (DCA) sys-
tem
— the Forward Emergency Braking (FEB) system
— the Predictive Forward Collision Warning (PFCW) system
. Some states or provinces have specific
regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
. Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts after
50 miles (80 km) of travel and at every
break.
. When launching a boat, do not allow the
water level to go over the exhaust tail pipe or
rear bumper.
. Make sure you disconnect the trailer lights (if
so equipped) before backing the trailer into
the water or the trailer lights may burn out.
When towing a trailer, the transmission
fluid should be changed more frequently.
For additional information, see the "9.
Maintenance and schedules" section.
TOW mode
Using TOW mode is recommended when pull-
ing a heavy trailer or hauling a heavy load. Push
the TOW MODE switch to activate tow mode.
The TOW MODE indicator light in the meter
illuminates when TOW mode is selected. Push
the TOW MODE switch again to turn TOW
mode off. TOW mode is automatically cancelled
when the ignition switch is placed in the OFF
position.
TOW mode includes the following features:
. Grade logic — Adjusts transmission shifts
when pulling a trailer or hauling a load up a
grade.
. Downhill Speed Control (DSC) — automa-
tically downshifts when driving down a
grade with a trailer or heavy load to help
control vehicle speed.
Driving the vehicle in the TOW mode with no
trailer/load or light trailer/light load will not cause
any damage. However, fuel economy may be
reduced and the transmission/engine driving
characteristics may feel unusual.
When towing a trailer, the transmission
fluid should be changed more frequently.
For additional information, see the "9.
Maintenance and schedules" section.
