service schedule INFINITI QX80 2020 User Guide

9-6Maintenance and schedules
Brake pads and rotors:
Check for wear, deterioration and fluid
leaks. Replace any deteriorated or damaged
parts immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler
and hangers for leaks, cracks, deterioration,
and damage. Tighten connections or replace
parts as necessary.
In-cabin microfilter:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
replace the filter more frequently.
Propeller shaft(s):
Check for damage, looseness, and grease
leakage. (4WD/RWD)
Steering gear and linkage, axle and suspen-
sion parts, drive shaft boots:
Check for damage, looseness, and leakage
of oil or grease. Under severe driving condi-
tions, inspect more frequently.
Tire rotation:
Tires should be rotated every 7,500 miles
(12,000 km) according to the instructions
under “Explanation of scheduled mainte-
nance items” (P.9-5). When rotating tires,
check for damage and uneven wear. Replace
if necessary.Transmission fluid/oil, differential oil and
transfer case oil:
Visually inspect for signs of leakage at
specified intervals.
To help ensure smooth, safe and economical
driving, INFINITI provides two maintenance
schedules that may be used, depending upon
the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 120,000 miles
(192,000 km)/96 months. For most people,
the odometer reading will indicate when
service is needed. However, if you drive very
little, your vehicle should be serviced at the
regular time intervals shown in the schedule.
After 120,000 miles (192,000 km)/96
months, continue maintenance at the same
mileage/time intervals.
ADDITIONAL MAINTENANCE
ITEMS FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditions;
should be performed
on vehicles that are driven under especially
demanding conditions. Additional mainte-
nance items should be performed if you
primarily operate your vehicle under the
following conditions:
. Repeated short trips of less than 5 miles
(8 km).
. Repeated short trips of less than 10 miles
(16 km) with outside temperatures re-
maining below freezing.
MAINTENANCE SCHEDULES

10-28Technical and consumer information
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
