CAPACITIES AND RECOMMENDED
FLUIDS/LUBRICANTS

ures caused by overloading are

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 sepa-
rately to determine axle loads. Indivi-
dual 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 ratings
are given on the vehicle certification
label. If weight ratings are exceeded,
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 perfor-
mance 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 vehicle
wear in at the heavier loads.
Your new vehicle was designed to be used
primarily to carry passengers and cargo.
Remember that towing a trailer places
additional loads on your vehicle’s engine,
drivetrain, steering, braking and other sys-
tems.
An INFINITI Towing Guide (U.S. only) is
available on the website at www.InfinitiUSA.com. This guide includes
information 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” (P.10-22). The total trailer
load equals trailer weight plus its cargo
weight.
.
When towing a trailer load of 3,500 lbs
(1,587 kg) or more, trailers with a brake
system MUST be used.
The maximum Gross Combined Weight
Rating (GCWR) should not exceed the value
specified in the following “Towing Load/
Specification” chart.

TOWING A TRAILER

10-28Technical and consumer information
down condition; check for improper
tongue load, overload, worn suspension
or other possible causes of either condi-
tion.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible in
the trailer to keep the trailer center of
gravity low.
. Load the trailer so approximately 60% of
the 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,
vehicle tire pressure, trailer light opera-
tion, 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
towing before driving the vehicle.
. Determine the overall height of the
vehicle and trailer so the required clear-
ance 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
prevent load shift while driving.
. Lock the trailer hitch coupler with a pin or
lock to prevent the coupler from inad-
vertently becoming unlatched.
. Avoid abrupt starts, acceleration or
stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moderate
speed. Some states or provinces have
specific speed limits for vehicles that are
towing trailers. Obey the local speed
limits.
. 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 possi-
ble, 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 lever to the P
(Park) position before blocking the
wheels and applying the parking brake,
transmission 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. 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 trailerare 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
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
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” (P.6-14).
. Trailer towing requires more fuel than
normal 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 recom-
mended maintenance schedule shown in
the “9. Maintenance and schedules”
section. .
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
being passed by larger vehicles, be pre-
pared 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 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
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. .
Use the TOW mode or 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
towing a trailer. Anticipate stops and
brake gradually.
. INFINITI recommends that the cruise
control not be used while towing a
trailer.
. While towing a trailer, do not use the
following systems (if so equipped):
— the Lane Departure Warning (LDW) system
(See “How to enable/disable the
LDW system” (P.5-24).)
— the Lane Departure Prevention (LDP) system
(See “How to enable/disable the LDP
system” (P.5-30).)
— the Blind Spot Warning (BSW) system (See “How to enable/disable the
BSW system” (P.5-36).)
— the Blind Spot Intervention
®(BSI)
system
Technical and consumer information10-29

10-30Technical and consumer information
(See “How to enable/disable the BSI
system” (P.5-45).)
— the Back-up Collision Intervention (BCI) system
(See “How to enable/disable the BCI
system” (P.5-58).)

— the Distance Control Assist (DCA) system
(See “How to enable/disable the DCA
system” (P.5-90).)
. 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
after 50 miles (80 km) of travel and at
every break.
. When launching a boat, do not 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.TOW mode
Using TOW mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Push the TOW mode switch to activate
TOW mode. The TOW mode indicator light
in the meter illuminates when TOW mode is
selected. Push the TOW mode switch again
to turn TOW mode off. TOW mode is
automatically cancelled when the ignition
switch is placed in the OFF position.
TOW mode includes the following features:
. Grade logic — Adjusts transmission shifts
when pulling a trailer or hauling a load up
a grade.
. Downhill Speed Control (DSC) — auto-
matically downshifts when driving down
a grade with a trailer or heavy load to
help control vehicle speed.
Driving the vehicle in the TOW mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel economy
may be reduced and the transmission/
engine driving characteristics may feel unu-
sual.
Trailer Sway Control
To minimize trailer sway, your vehicle may
apply braking to individual wheels based on
input from your vehicle sensors and vehicle
speed. Trailer Sway Control is a function of
the Vehicle Dynamic Control (VDC) system and is active when the VDC function is
enabled.
CAUTION
If the VDC OFF switch is on (meaning
VDC system OFF), the Trailer Sway
Control is also disabled.
When Trailer Sway Control is in operation,
the VDC warning light blinks. When vehicle
control is regained, VDC warning light will
turn OFF.
For additional information about the VDC
system, see “Vehicle Dynamic Control (VDC)
system” (P.5-135).
If Trailer Sway Control activates:
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.
CAUTION
Do not try to correct trailer sway by
steering or applying the brakes.
