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. Addi-
tional engine cooling system additives are not
necessary.
WARNING
●Never remove the radiator or coolant reser-
voir 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” in the “6.
In case of emergency” section of this
manual.
● The radiator is equipped with a pressure
type radiator cap. To prevent engine dam-
age, use only a genuine NISSAN radiator cap.
CAUTION
●When adding or replacing coolant, be sure to
use only Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent. Genu-
ine NISSAN Long Life Antifreeze/Coolant
(blue) is pre-diluted to provide antifreeze pro-
tection to 34°F (37°C). If additional freeze
protection is needed due to weather where
you operate your vehicle, add Genuine NISSAN
Long Life Antifreeze/Coolant (blue) concen-
trate following the directions on the con-
tainer. If an equivalent coolant other than
Genuine NISSAN Long Life Antifreeze/Coolant
(blue) is used, follow the coolant manufactur-
er’s instructions to maintain minimum anti-
freeze protection to 34°F (37°C). The use of
other types of coolant solutions 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. Mix-
ing any other type of coolant other than Genu-
ine 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 coolant. Refer to the Nissan
Service and Maintenance Guide for more
details.

any other type of coolant or the use of non-

the factory-fill coolant. Refer to the INFINITI Ser-
vice and Maintenance Guide for more details.
The use of other types of coolant solutions may

ENGINE COOLING SYSTEM
Maintenance and do-it-yourself8-7

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. This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue). The life expectancy 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 expectancy of the factory-fill
coolant. Refer to the INFINITI Service and Main-
tenance Guide for more details.
If the cooling system requires coolant fre-
quently, have it checked by an INFINITI retailer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by an INFINITI retailer. The service pro-
cedures can be found in the appropriate INFINITI
Service Manual.
Improper servicing can result in reduced heater
performance and engine overheating.
WARNING
●
To avoid the danger of being scalded, never
change the coolant when the engine is hot.
● Never remove the radiator cap or coolant res-
ervoir 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.
Engine coolant must be disposed of properly.
Check your local regulations.

8-8Maintenance and do-it-yourself

WARNING
Antifreeze is poisonous and should be stored
carefully in marked containers out of the reach
of children.Fill the window washer fluid reservoir periodi-
cally. Add window washer fluid when the low
window washer fluid warning illuminates.
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window
washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a wind-
shield washer antifreeze. Follow the manufac-
turer’s instructions for the mixture ratio.
Refill the reservoir more frequently when driv-
ing conditions require an increased amount of
window washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Antifreeze
or equivalent.
CAUTION
●
Do not substitute engine anti-freeze coolant
for window washer solution. This may result
in damage to the paint.
● Do not fill the window washer reservoir tank
with washer fluid concentrates at full
strength. Some methyl alcohol based
washer fluid concentrates may permanently
stain the grille if spilled while filling the win-
dow washer reservoir tank.
● Pre-mix washer fluid concentrates with wa-
ter to the manufacturer’s recommended lev-
els before pouring the fluid into the window
washer reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer
fluid concentrate and water.

CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS
9-2Technical and consumer information

Always block the wheels on both vehicle and
trailer when parking. Parking on a slope is not
recommended; however, if you must do so:
CAUTION
If you move the shift selector lever to the P
(Park) position before blocking the wheels and
applying the parking brake, transmission dam-
age could occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the down-hill 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 de-
crease overall stability. Therefore, to main-
tain 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
OVERHEATS” in the “6. In case of emer-
gency” section.
● Trailer towing requires more fuel than nor-
mal 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 in the INFINITI Service
and Maintenance Guide.
● 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
causing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle 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.
