2014 INFINITI QX70 maintenance

9-6Technical and consumer information
above symptoms are encountered, have
your vehicle checked at an INFINITI retailer
or other competent service facility.
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.

ENGINE OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” (P.9-2). INFINITI recommends
the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification and SAE viscosity standard.
These oils have the API certification mark
on the front of the container. Oils which do
not have the specified quality label should
not be used as they could cause engine
damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.

Oil which may contain foreign matter or
has been previously used should not be
used.
Oil viscosity
The engine oil viscosity or thickness
changes with temperature. Because of this,
it is important that the engine oil viscosity
be selected based on the temperatures at
which the vehicle will be operated before
the next oil change. Choosing an oil
viscosity other than that recommended
could cause serious engine damage.
Selecting the correct oil filter
Your new vehicle is equipped with a high-
quality genuine NISSAN oil filter. When
replacing, use the genuine oil filter or its
equivalent for the reason described in
change intervals.
Change intervals
The oil and oil filter change intervals for
your engine are based on the use of the
specified quality oils and filters. Oil and
filter other than the specified quality, or oil
and filter change intervals longer than
recommended could reduce engine life.
Damage to engines caused by improper
maintenance or use of incorrect oil andfilter quality and/or viscosity is not covered
by the new INFINITI vehicle limited warran-
ties.
Your engine was filled with a high quality
engine oil when it was built. You do not
have to change the oil before the first
recommended change interval. Oil and
filter change intervals depend upon how
you use your vehicle. Operation under the
following conditions may require more
frequent oil and filter changes.
.
repeated short distance driving at cold
outside temperatures,
. driving in dusty conditions,
. extensive idling,
. towing a trailer,
. stop and go “rush hour”traffic,
Refer to the “INFINITI Service and Main-
tenance Guide” for the maintenance sche-
dule.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND LUBRICANT RE-
COMMENDATIONS
The air conditioning system in your
INFINITI vehicle must be charged with the
refrigerant HFC-134a (R-134a) and the
lubricant, NISSAN A/C system oil Type S
or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.

inadvertently 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
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 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. 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 overloading 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 con-
trol to the HOT position.
. Trailer towing requires more fuel than
normal 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 compen-
sate 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
prepared for possible changes in cross-
winds that could affect vehicle hand-

ling. If swaying does occur, firmly grip
the steering wheel, steer straight
ahead, and immediately (but gradually)
reduce 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 condi-
tions allow. This combination will help
stabilize the vehicle.
.Do not correct trailer sway by steer-ing 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 nor-
mal passing. 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
regulations and speed limits for vehi-
cles 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 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 additional 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, al-
ways tow forward, never backward.
. DO NOT tow any automatic transmission
vehicle with all four wheels on the
ground (flat towing). Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
Technical and consumer information9-27

WARNING
A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dynam-
ometers used by some states for emissions
testing), or similar equipment. Make sure
you inform test facility personnel that your
vehicle is equipped with AWD 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 da-
mage or personal injury.
Due to legal requirements in some states/
areas or provinces, your vehicle may be
required 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 readycondition”
. Before taking the I/M test,
check the vehicle’ s inspection/mainte-
nance test readiness condition. 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 the
“ready condition” or to prepare the vehicle
for testing. This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or
less. The EDR in this vehicle is designed to
record such data as:
.
How various systems in your vehicle
were operating;
. Whether or not the driver and passen-
ger safety belts were buckled/fastened;
. How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your
vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR
under normal driving conditions and no
personal data (e.g. name, gender, age and
