CAUTION
Damage to engine caused by improper
maintenance or use of incorrect oil and fil-
ter quality and/or viscosity is not covered
by the INFINITI New Vehicle Limited
Warranty.
Your engine was filled with a high-quality
engine oil when it was built. You do not have
to change the oil before the first recom-
mended change interval. Oil and filter change
intervals depend upon how you use your ve-
hicle.
Operation under the following conditions
may require more frequent oil and filter
changes: ∙ repeated short distance driving at cold outside temperatures
∙ driving in dusty conditions
∙ extensive idling
∙ towing a trailer
∙ stop and go commuting
For additional information on maintenance
schedules, refer to the “Maintenance and
schedules” section of this manual.
AIR CONDITIONER SYSTEM
REFRIGERANT AND OIL
RECOMMENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refrigerant
HFC-134a (R-134a) and the oil, Genuine
NISSAN A/C System Oil Type ND-OIL8 or
the exact equivalents.
CAUTION
The use of any other refrigerant or oil will
cause severe damage to the air condition-
ing system and will require the replacement
of all air conditioner system components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle does not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
government regulations require the recovery
and recycling of any refrigerant during auto-
motive air conditioner system service. An
INFINITI retailer has the trained technicians
and equipment needed to recover and recycle
your air conditioner system refrigerant.
It is recommended that you visit an INFINITI
retailer when servicing your air conditioner
system.

WARNING
∙ Properly secure all cargo with ropes orstraps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
∙ The child restraint top tether strap may be damaged by contact with items in the
cargo area. Secure any items in the cargo
area. Your child could be seriously injured
or killed in a collision if the top tether
strap is damaged.
∙ Do not load your vehicle any heavier than the GVWR or the maximum front and
rear GAWRs. If you do, parts of your ve-
hicle can break, tire damage could occur,
or it can change the way your vehicle
handles. This could result in loss of con-
trol and cause personal injury.
LOADING TIPS
∙ The GVW must not exceed GVWR
or GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label.
∙ Do not load the front and rear axle to the GAWR. Doing so will exceed
the GVWR.
WARNING
∙ Properly secure all cargo with ropes or straps to help prevent 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 result in loss of
control and cause personal injury. ∙ Overloading not only can shorten
the life of your vehicle and the tire,
but can also cause unsafe vehicle
handling and longer braking dis-
tances. This may cause a prema-
ture tire failure which could result
in a serious accident and personal
injury. Failures caused by over-
loading are not covered by the ve-
hicle’s warranty.MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of
your vehicle. When the vehicle is
loaded, drive to a scale and weigh the
front and the rear wheels separately
to determine axle loads. Individual axle
loads should not exceed either of the
gross axle weight ratings (GAWR). The
total of the axle loads should not ex-
ceed the gross vehicle weight rating
(GVWR). These ratings are given on
the vehicle certification label. If weight
ratings are exceeded, move or remove
items to bring all weights below the
ratings.
Technical and consumer information10-17

∙ Load the trailer so approximately 60% ofthe trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
∙ Check your hitch, trailer tire pressure, ve- hicle tire pressure, trailer light operation,
and trailer wheel lug nuts every time you
attach a trailer to the vehicle.
∙ Be certain your rearview mirrors conform to all federal, state or local regulations. If
not, install any mirrors required for tow-
ing before driving the vehicle.
∙ Determine the overall height of the ve- hicle and trailer so the required clearance
is known.
Trailer towing tips
In 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 performance will be somewhat
different than under normal driving condi-
tions.
∙ Always secure items in the trailer to pre- vent load shift while driving. ∙ Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inadver-
tently becoming unlatched.
∙ Avoid abrupt starts, acceleration or stops.
∙ Avoid sharp turns or lane changes.
∙ Always drive your vehicle at a moderate speed.
∙ 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 back-
ing 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:
CAUTION
If you move the shift selector 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. Start the vehicle.
2. Apply and hold the brake pedal.
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 thetrailer 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 overheat-
ing. Shifting to a lower gear instead pro-
vides “engine braking” and reduces the
need to brake as frequently.
∙ If the engine coolant temperature rises to a high temperature, refer to “If your ve-
hicle overheats” in the “In case of emer-
gency” section of this manual.
∙ Trailer towing requires more fuel than normal circumstances.
∙ Avoid towing a trailer for your vehicle’s first 500 miles (805 km).
∙ For the first 500 miles (805 km) that you do tow, do not drive over 50 mph
(80 km/h).
∙ Have your vehicle serviced more often than at intervals specified in the recom-
mended maintenance schedule in the
“Maintenance and schedules” section of
this manual. ∙ 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 ad- versely affect vehicle/trailer handling,
possibly causing vehicle sway. When be-
ing 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 or applying the brakes.
2. When the trailer sway stops, gently ap- ply 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 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 can safely change lanes.
∙ 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 re-
duced braking efficiency.
∙ Increase your following distance to allow for greater stopping distances while
towing a trailer. Anticipate stops and
brake gradually.
∙ INFINITI recommends that the cruise control not be used while towing a trailer.
∙ Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
Technical and consumer information10-27

∙ Check your hitch, trailer wiring harnessconnections, and trailer wheel lug nuts
after 50 miles (80 km) of travel and at
every break.
∙ When launching a boat, don’t allow the water level to go over the exhaust tail
pipe or rear bumper.
∙ Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more frequently.
For additional information, refer to the “Do-
it-yourself” section of this manual.
FLAT TOWING FOR ALL–WHEEL
DRIVE VEHICLE (if so equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.
CAUTION
∙ Failure to follow these guidelines can re- sult in severe transmission damage.
∙ Never flat tow your All-wheel drive (AWD) vehicle.
∙ DO NOT tow your All-wheel drive (AWD) vehicle with any wheels on the ground.
Doing so may cause serious and expen-
sive damage to the powertrain.
∙ For emergency towing procedures refer to “Towing recommended by INFINITI” in
the “In case of emergency” section of this
manual.
FLAT TOWING FOR FRONT
WHEEL DRIVE VEHICLE (if so
equipped)
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when towing
a vehicle behind a recreational vehicle, such
as a motor home.
CAUTION
∙ Failure to follow these guidelines can re-sult in severe transmission damage.
∙ Whenever flat towing your vehicle, al- ways tow forward, never backward.
∙ Never tow your front wheel drive vehicle with the front tires on the ground. Doing
so may cause serious and expensive dam-
age to the powertrain.
∙ DO NOT tow your front wheel drive con- tinuously variable transmission vehicle
with all four wheels on the ground (flat
towing). Doing so WILL DAMAGE inter-
nal transmission parts due to lack of
transmission lubrication.
∙ For emergency towing procedures refer to “Towing recommended by INFINITI” in
the “In case of emergency” section of this
manual.
Continuously Variable Transmission
To tow a vehicle equipped with a continu-
ously variable transmission, an appropriate
vehicle dolly MUSTbe placed under the
towed vehicle’s drive wheels. Alwaysfollow
the dolly manufacturer’s recommendations
when using their product.
