• Avoid towing a trailer for your vehicle's first500 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 recommended
maintenance schedule in “Maintenance and
schedules” (P. 9-2).
• 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
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 al-
low. 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 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 in this section.
• 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.
• 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 reduced
braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• INFINITI recommends that the cruise con- trol 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. • Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts af-
ter 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, see“ Do-it-yourself”
(P. 8-2).
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.
10-28Technical and consumer information

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
expensive damage to the powertrain.
• For emergency towing procedures see
“Towing recommended by INFINITI”
(P. 6-8).
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 see
“Towing recommended by INFINITI”
(P. 6-8).
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.
NOTE:
It the battery is completely drained the
transmission will not manually shift to other
positions. 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 appli-
cable on the tire sidewall between tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one and
one-half (1 1/2) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon the
actual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.
