CAUTION
●Do not add brake fluid with the ignition
switch in the “ON” position or the engine
running. Doing so could make the brake fluid
overfill when the ignition switch is turned
off.
● Do not spill the fluid on painted surfaces.
This will damage the paint. If fluid is spilled,
wash the surface with water.
BRAKE FLUID
Check the fluid level in the reservoir. If the fluid
is below the MIN line
1or the brake warning
light comes on, add Genuine NISSAN Super
Heavy Duty Brake Fluid or equivalent DOT 3fluid
up to the MAX line
2.
To add brake fluid:
1. Be sure the ignition switch is in the OFF or LOCK position.
2. Depress and release the foot brake pedal more than 40 times. 3. Open the reservoir filler cap and add
brake fluid up to the MAX line
2. (See
“CAPACITIES AND RECOMMENDED FUEL/
LUBRICANTS” in the “9. Technical and
consumer information” section for the

E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed on
level roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.
CAUTION
●Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline.
● U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.

9-8Technical and consumer information

A weight-distributing hitch system (Class IV) is
recommended if you plan to tow trailers with a
maximum weight over 5,000 lbs (2,267 kg).
Check with the trailer and towing equipment
manufacturers to determine if they recommend
the use of a weight-distributing hitch system.
NOTE:
A weight-distributing hitch system may affect
the operation of trailer surge brakes. If you are
considering use of a weight-distributing hitch
system with a surge brake-equipped trailer,
check with the surge brake, hitch or trailer
manufacturer to determine if and how this can be
done.
Follow the instructions provided by the manu-
facturer for installing and using the weight-
distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface.With the ignition switch in the ON position
and the doors closed, allow the vehicle to
stand for several minutes so that it can
level.
2. Measure the height of a reference point on the front and rear bumpers at the
center of the vehicle. 3. Attach the trailer to the vehicle and adjust
the hitch equalizers so that the front
bumper height is within0-.5inches (0 -
13 mm) of the reference height measured
in step 2. The rear bumper should be no
higher than the reference height mea-
sured in step 2.
WARNING
Properly adjust the weight distributing hitch so
the rear of the bumper is no higher than the
measured reference height when the trailer is
attached. If the rear bumper is higher than the
measured reference height when loaded, the
vehicle may handle unpredictably which could
cause a loss of vehicle control and cause seri-
ous personal injury or property damage.
Sway control device
Sudden maneuvers, wind gusts and buffeting
caused by other vehicles can affect trailer han-
dling. Sway control devices may be used to help
control these affects. If you choose to use one,
contact a reputable trailer hitch supplier to
make sure the sway control device will work
with the vehicle, hitch, trailer and the trailer’s
brake system. Follow the instructions provided
by the manufacturer for installing and using the
sway control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 2,000 lb (907 kg).
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 3,500 lb (1,588 kg).
Class III hitch
Class III trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow trailers
of a maximum weight of 5,000 lb (2,267 kg).
Class IV hitch
Class IV trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 10,000 lb
(4,545 kg). A weight distributing hitch should be
used to tow trailers that weigh over 5,000 lb
(2,267 kg).
Your vehicle may be equipped with Class IV
trailer hitch equipment that has a 10,000 lb
(4,545 kg) maximum weight rating, but your
vehicle is only capable of towing the maximum
trailer weights shown in the “Towing
Load/Specification” chart earlier in this section.
Technical and consumer information9-23

3. Try to rearrange the trailer load so it isbalanced 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.
● Use the Tow mode or downshift the trans-
mission 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 follow-
ing systems (if so equipped):
– the Lane Departure Prevention (LDP) sys- tem
– the Blind Spot Warning (BSW) system
– the Intelligent Cruise Control (ICC) system
– the Distance Control Assist (DCA) system
– Intelligent Brake Assist ( IBA) system
● 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 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.
When towing a trailer, the transmission fluid
should be changed more frequently. For addi-
tional information, see the INFINITI Service and
Maintenance Guide.
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 illumi-
nates 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) — automati-
cally 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 driv-
ing characteristics may feel unusual.
When towing a trailer, final drive gear oil should
be replaced and transmission oil/fluid should be
changed more frequently. For additional infor-
mation, see the 9. “Technical and consumer in-
formation” section later in this manual.

A vehicle equipped with Four-Wheel Drive (4WD)
should never be tested using a two wheel
dynamometer (such as the dynamometers used
by some states for emissions testing), or similar
equipment. Make sure you inform test facility
personnel that your vehicle is equipped with
4WD before it is placed on a dynamometer.
Using the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready
condition” for an Inspection/Maintenance (I/M)
test of the emission control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds, the I/M
test condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
Contact an INFINITI retailer to set “ready condi-
tion” or to prepare the vehicle for testing.
