maintenance INFINITI QX80 2021 Repair Manual

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 and filter quality and/or vis-
cosity is not covered by the new INFINITI
vehicle limited warranties.
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 recom-mended change interval. Oil and filter
change intervals depend upon how you use
your vehicle.
AIR CONDITIONING SYSTEM RE-
FRIGERANT AND OIL RECOM-
MENDATIONS
The air conditioner system in your INFINITI
vehicle must be charged with the refriger-
ant HFO-1234yf (R-1234yf) and NISSAN
A/C System Oil VC100YF (PAG) or the
exact equivalents.
CAUTION
The use of any other refrigerant or oil
will cause severe damage to the air
conditioning system and will require the
replacement of all air conditioner system
components.
The refrigerant HFO-1234yf (R-1234yf) in
your INFINITI vehicle does not harm the
earth’s ozone layer. Although this refrigerant
does not affect the earth’s atmosphere,
certain government regulations require the
recovery and recycling of any refrigerant
during automotive air conditioner system
service. Air conditioner system should only
be serviced by trained and certified techni- cians to ensure proper and safe operation
(SAE J2845). An INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioner
system refrigerant. Only new and
SAEJ2842 certified evaporator(s) shall be
used as replacement parts.
A damaged or leaking air conditioning
evaporator shall never be repaired or re-
placed with one removed from a used or
salvaged vehicle. To replace a damaged or
leaking evaporator, use only new and SAE
J2842 certified evaporator(s). It is recom-
mended that you visit an INFINITI retailer
when servicing your air conditioner system.

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
— the Lane Departure Prevention (LDP) system
— the Blind Spot Warning (BSW) system
— the Blind Spot Intervention
®(BSI)
system
— the Back-up Collision Intervention (BCI) system
— the Intelligent Cruise Control (ICC) system
— the Distance Control Assist (DCA) system

WARNING
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 move-
ment which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states and
Canadian 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 re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready condi-
tion”. Before taking the I/M test, check the
vehicle’s inspection/maintenance test readi- ness 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”.
It is recommended you visit an INFINITI
retailer to set “ready condition” or to prepare
the vehicle for testing.
