8-10Maintenance and do-it-yourself
CAUTION
.Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause
damage to the engine, transmission
and/or cooling system.
. When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is pre-diluted to
provide antifreeze protection to −348F
(−378C). If additional freeze protection is
needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) is used,
follow the coolant manufacturer’s in-
structions to maintain minimum anti-
freeze protection to −348F (−378C). 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. 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 coolant.
Refer to the INFINITI Service and Main-
tenance Guide for more details.

WARNING
Be sure the ignition switch is in the OFF or
LOCK position before servicing drive belts.
The engine could rotate unexpectedly.
1. Visually inspect each belt for signs of
unusual wear, cuts, fraying or loosen- ess. If the belt is in poor condition or
loose, have it replaced or adjusted by
an INFINITI retailer.
2. Have the belts checked regularly for condition and tension in accordance
with the maintenance schedule in your
“INFINITI Service and Maintenance
Guide”.

9-26Technical and consumer information
CAUTION
If you move the shift selector lever to the P
(Park) position before blocking the wheels
and applying the parking brake, transmis-
sion 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. 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.
. 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 overloading 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 opening the
windows, switching the fan control to
high and setting the temperature con-
trol to the HOT position.
. Trailer towing requires more fuel than
normal circumstances.
. Avoid towing a trailer for the 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 compen-
sate for this, make a larger than normal
turning radius during the turn.
. Crosswinds and rough roads will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be
prepared for possible changes in cross-
winds that could affect vehicle hand-
