you
should first find out if the fuel available is
suitable for your vehicle’s engine.
Using fuel with too low an octane rating may
cause engine damage. All gasoline vehicles
must be operated with unleaded gasoline.
Therefore, avoid taking your vehicle to areas
where appropriate fuel is not available.
When transferring the registration of your ve-
hicle to another country, state, province or dis-
trict, it may be necessary to modify the vehicle
to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into another
country, state, province or district and regis-
tered, its modifications, transportation, and reg-
istration are the responsibility of the user.

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 exceed the gross
vehicle weight rating (GVWR). These rat-
ings are given on the vehicle certifica-
tion label. If weight ratings are ex-
ceeded, move or remove items to bring
all weights below the ratings.
WARNING
Overloading or improper loading of a trailer and
its cargo can adversely affect vehicle handling,
braking and performance 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.
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, drivetrain, steer-
ing, braking and other systems.
An INFINITI Towing Guide (U.S. only) is available
on the website at
www.InfinitiUSA.com. This guide includes infor-
mation on trailer towing capability and the
special equipment required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the “Towing
Load/Specification” chart. The total trailer load
equals trailer weight plus its cargo weight.
● When towing a trailer load of 1,000 lbs (454
kg) or more, trailers with a brake system
MUST be used.
The maximum GCWR (Gross Combined Weight
Rating) should not exceed the value specified in
the following “Towing Load/Specification”
chart.
TOWING A TRAILER
Technical and consumer information9-19
—
—
08/03/09—pattie
The GCWR equals the combined weight of the
towing vehicle (including passengers and
cargo) plus the total trailer load. Towing loads
greater than these or using improper towing
equipment could adversely affect vehicle han-
dling, braking and performance.
The ability of your vehicle to tow a trailer is not
only related to the maximum trailer loads, but
also the places you plan to tow. Tow weights
appropriate for level highway driving may have
to be reduced on very steep grades or for low
traction situations (for example, on slippery
boat ramps).
Temperature conditions can also affect towing.
For example, towing a heavy trailer in high
outside temperatures on graded roads can af-fect engine performance and cause overheat-
ing. The transmission high fluid temperature
protection mode, which helps reduce the
chance of transmission damage, could activate
and automatically decrease engine power. Ve-
hicle 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 engine
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” in the “6. In case of
emergency” section of this manual.
CAUTION
Vehicle damage resulting from improper tow-
ing procedures are not covered by INFINITI
warranties.
Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load be-
tween 10 to 15% of the total trailer load 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.

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:
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. 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 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
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
● Trailer towing requires more fuel than nor-
mal 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 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. If swaying does occur, firmly
grip the steering wheel, steer straight
ahead, and immediately (but gradually) re-
duce vehicle speed. This combination will
help stabilize the vehicle. Never increase
speed.
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 sec-
tion.

●Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Down shift 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.
● Do not use cruise control while towing a
trailer.
● Some states or provinces have specific regu-
lations and speed limits for vehicles that are
towing trailers. Obey the local speed limits.
● Check your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
● When stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position. ●
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, the transmission fluid
should be changed more frequently. For addi-
tional information, see the “8. Maintenance and
do-it-yourself” section earlier in this manual.
FLAT TOWING
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 result
in severe transmission damage.
● Whenever flat towing your vehicle, always
tow forward, never backward.
● DO NOT tow any automatic transmission ve-
hicle with all four wheels on the ground (flat
towing). Doing so WILL DAMAGE internal
transmission parts due to lack of transmis-
sion lubrication. ●
DO NOT tow an All-Wheel Drive (AWD) ve-
hicle with any of the wheels on the ground.
Doing so may cause serious and expensive
damage to the powertrain.
● For emergency towing procedures refer to
“TOWING RECOMMENDED BY INFINITI” in the
“6. In case of emergency” section of this
manual.
Automatic transmission
All-Wheel Drive (AWD) models :
Do not tow an AWD vehicle with any of the
wheels on the ground.
Two-Wheel Drive (2WD) models :
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dolly
MUST be placed under the towed vehicle’s drive
wheels. Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
