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 tem-
perature 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 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 when the coolant tempera-
ture is high.
7. After the engine cools down, check the cool-
ant level in the reservoir tank with the engine
running. Add coolant to the reservoir tank if
necessary. Have your vehicle repaired at a
NISSAN dealer.When towing your vehicle, all State (Provincial 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 appli-
cable laws and procedures for towing. To assure
proper towing and to prevent accidental damage
to your vehicle, NISSAN recommends having a
service operator tow your vehicle. It is advisable
to have the service operator carefully read the
following precautions.
WARNING

Never ride in a vehicle that is being
towed.

Never get under your vehicle after it
has been lifted by a tow truck.
CAUTION

When towing, make sure that the
transmission, axles, steering system
and powertrain are in working condi-TOWING YOUR VEHICLE

CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING

To avoid being scalded, never change
the coolant when the engine is hot.

Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping 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 children
and pets.
1. Open radiator drain plug at the bottom of
radiator, and remove radiator filler cap.

Be careful not to allow coolant to con-
tact drive belts.

Waste coolant must be disposed of
properly. Check your local regulations.
2. Close the radiator drain plug securely after
the coolant is drained.3. Fill the radiator slowly with the proper mixture
of anti-freeze solution and demineralized
water/distilled water. Fill the reservoir tank up
to the MAX level. Then install the radiator filler
cap.
4. Start the engine and warm it up until it
reaches normal operating temperature. Then
race the engine 2 or 3 times under no load.
Watch the engine coolant temperature
gauge for signs of overheating.
5. Stop the engine. After it completely cools
down, refill the radiator up to the filler open-
ing. Fill the reservoir tank up to the MAX level.
Check the drain plug for any sign of leakage.
6. Recheck the coolant level after the vehicle
has been driven for a day.

Platinum-tipped spark plugsIt is not necessary to replace the platinum-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance log but, do not reuse
them by cleaning or regapping.
Always replace with recommended
platinum-tipped spark plugs.To remove the filter from the air cleaner, pull off
the lock pins

The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the Service and Maintenance
Guide. When replacing the filter, wipe the inside
of the air cleaner housing and the cover with a
damp cloth.
WARNING

Operating the engine with the air
cleaner removed can cause you orothers to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it is
not there, and the engine backfires,
you could be burned. Do not drive
with the air cleaner removed, and be
careful when working on the engine
with the air cleaner removed.

Never pour fuel into the throttle body
or attempt to start the engine with

1. With the engine off, press and release the
brake pedal several times. When brake pedal
movement (distance of travel) remains the
same from one pedal application to the next,
continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, see a
NISSAN dealer.Some vehicles are equipped with engine com-
partment and passenger compartment fuse
boxes that use only type
A
fuses. Other ve-
hicles are equipped with typeA
fuses in the

WARNING

Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.

Do not load your vehicle any heavier
than the GVWR or the maximum front
and rear GAWRs. If you do, parts of
your vehicle can break, tire damage
could occur, or it can change the way
your vehicle handles. This could re-
sult in loss of control and cause per-
sonal injury.

Overloading not only could shorten
the life of your vehicle and the tires,
but also could lead to unsafe vehicle
handling and long braking distance.
This could cause a premature tire
malfunction, which could result in a
serious accident and personal injury.
Failures caused by overloading are
not covered by the vehicle’s warranty.Roadster model:
Do not tow a trailer with your vehicle.
Coupe model:
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer places additional
loads on your vehicle’s engine, drive train, steer-
ing, braking and other systems.
ANISSAN Trailer Towing Guide(US only) is
available from a NISSAN dealer. This guide
includes information on trailer towing ability and
the special equipment required for proper tow-
ing.
WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION

Do not tow a trailer or haul a heavy
load for the first 500 miles (800 km).
Your engine, axle or other parts
could be damaged.

For the first 500 miles (800 km) that
you tow a trailer, do not drive over 50
mph (80 km/h) and do not make
starts at full throttle. This helps the
engine and other parts of your ve-
hicle wear in at the heavier loads.MAXIMUM LOAD LIMITS
Maximum trailer loadsNever allow the total trailer load to exceed 1,000
lb(454 kg). The total trailer load equals trailer

the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. When wiring the vehicle for
towing, connect the stop and tail light pickup
into the vehicle electrical circuit at a point be-
tween the sensor and stop light or light switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Pre-towing tips
Be certain a vehicle maintains a level position
when a loaded and/or unloaded trailer is
hitched. Do not drive the vehicle if it has an
unusual nose-up or nose-down condition;
check for improper tongue load, overload,
worn suspension or other possible causes of
these conditions.
Always secure items in the trailer to prevent
load shifts while driving.

Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.

Check your hitch, trailer tire pressure, vehicle
tire pressure, trailer light operation, and trailer
wheel lug nuts every time you attach a trailer
to the vehicle.

Be certain your rear view mirrors conform to
all federal, state and/or local regulations. If
not, install any mirrors required for towing
before driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability, and braking per-
formance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive a vehicle at a moderate speed.
Some states or provinces have specificspeed limits for vehicles that are towing
trailers. Obey the local speed limits.

When backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and back
up slowly. If possible, have someone guide
you when you are backing up.

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so,
and if a vehicle is equipped with automatic
transmission, first apply the parking brake
and block the wheels, and then move the
transmission selector lever into the P (Park)
position. If you move the selector lever to the
P (Park) position before blocking the wheels
and applying the parking brake, the transmis-
sion may get damaged.

When going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine overload-
ing and/or overheating.

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by

AUTOMATIC TRANSMISSIONTo tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.MANUAL TRANSMISSION
Always tow with the manual transmission in
Neutral.

After towing 500 miles, start and idle the
engine with the transmission in Neutral for
two minutes. Failure to idle the engine after
every 500 miles of towing may cause damage
to internal transmission parts.DOT (Department Of Transportation) Quality
Grades: All passenger car tires must conform to
federal safety requirements in addition to these
grades.
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
TreadwearTreadwear grade is a comparative rating based
on tire wear rate when tested under controlled
conditions on specified government test
courses. For example, a tire graded 150 would
wear one and a half (1-1/2) times as well on the
government course as a tire graded 100. How-
ever, relative tire performance depends on actual
driving conditions, and may vary significantly
from the norm due to variations in driving habits,
service practices and differences in road char-
acteristics and climate.Traction AA, A, B and CThe traction grades, from highest to lowest, are
AA, A, B, and C. Those grades represent the
tire’s ability to stop on wet pavement as mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-crete. A tire marked C may have poor traction
performance.
WARNING
The traction grade assigned to your ve-
hicle tires is based on straight-ahead
braking traction tests and does not in-
clude acceleration, cornering, hydro-
planing or peak traction characteristics.Temperature A, B and CTemperature grades are A (the highest), B, and
C. They represent a tire’s resistance to heat
build-up, and its ability to dissipate heat when
tested under controlled conditions on a speci-
fied indoor laboratory test wheel. Sustained high
temperature can cause tire material to degener-
ate, reducing tire life. Excessive temperatures
can lead to sudden tire failure. Grade C corre-
sponds to a performance level which all passen-
ger car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades A and
B represent higher levels of performance on
laboratory test wheels than the minimum re-
quired by law.

Due to legal requirements in some states/
areas, your vehicle may be required to be in what
is called the “ready condition” for an Inspection/
Maintenance (I/M) test of the emission control
system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a not “ready condition”. Before taking
the I/M test, check the vehicle’s inspection/
maintenance test readiness condition. Turn the
ignition switch ON without starting the engine. If
the Malfunction Indicator Lamp (MIL) comes on
steady for 20 seconds and then blinks for 10
seconds, the I/M test condition is “not ready”. If
the MIL does not blink after 20 seconds, the I/M
test condition is “ready”.
If the MIL indicates the vehicle is in a “not ready”
condition, drive the vehicle through the following
pattern to set the vehicle to the ready condition.
If you cannot or do not want to perform the
driving pattern, a NISSAN dealer can conduct it
for you.
WARNING
Always drive the vehicle in a safe and
prudent manner according to traffic
conditions and obey all traffic laws.
1. Start the engine. Allow the engine to idle until
the engine coolant temperature gauge needle
points between the C and H (normal operat-
ing temperature).
2. Accelerate the vehicle to 55 MPH (88 km/h),
then quickly release the accelerator pedal
completely and keep it released for at least
10 seconds.
3. Quickly depress the accelerator pedal for a
moment, then drive the vehicle at a speed of
53 to 60 MPH (86 to 96 km/h) for at least 9
minutes.
4. Stop the vehicle. Leave the engine running.
5. Accelerate the vehicle to 35 MPH (55 km/h)
and maintain the speed for 20 seconds.
6. Repeat steps 4 and 5 at least 10 times.
7. Accelerate the vehicle to 55 MPH (88 km/h)
and maintain the speed for at least 3 minutes.
8. Stop the vehicle. Place the automatic trans-mission gear selector lever in the P (Park) or
N (Neutral) position or the manual transmis-
sion shift lever in the N position.
9. Turn the engine off.
10. Repeat steps 1 through 8 at least one more
time.
If step 1 through 7 is interrupted, repeat the
preceding step. Any safe driving mode is ac-
ceptable between steps. Do not stop the engine
until step 7 is completed.
