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.

FUEL RECOMMENDATION:
VK56VD engine
INFINITI recommends the use of unleaded pre-
mium gasoline with an octane rating of at least
91 AKI (Anti-Knock Index) number (Research
octane number 96).
If unleaded premium gasoline is not available,
you may use unleaded regular gasoline with an
octane rating of at least 87 AKI number (Re-
search octane number 91), but you may notice a
decrease in performance.
CAUTION
●Using a fuel other than that specified could
adversely affect the emission control sys-
tems, and may also affect warranty
coverage.
● Under no circumstances should a leaded
gasoline be used, since this will damage the
three way catalyst.
● Do not use E-85 fuel in your vehicle. Your
vehicle is not designed to run on E-85 fuel.
Using E-85 fuel can damage the fuel system
components and is not covered by the
INFINITI vehicle limited warranty.
ENGINE OIL RECOMMENDATION:
● Engine oil with API Certification Mark
● Viscosity SAE 5W-30
See “CAPACITIES AND RECOMMENDED
FUEL/LUBRICANTS” in the “9. Technical and
consumer information” section for engine oil
and oil filter recommendation.
COLD TIRE PRESSURES:
The label is typically located on the driver side
center pillar or on the driver’s door. For addi-
tional information, see “WHEELS AND TIRES” in
the “8. Maintenance and do-it-yourself” sec-
tion.
NEW VEHICLE BREAK-IN PROCEDURES
RECOMMENDATION:
During the first 1,200 miles (2,000 km) of
vehicle use, follow the recommendations out-
lined in the “BREAK-IN SCHEDULE” in the “5.
Starting and driving” section of this Owner’s
Manual. Follow these recommendations for the
future reliability and economy of your new
vehicle.
