2018 INFINITI QX30 maintenance schedule

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
•Use the recommended viscosity engine oil.
For additional information, see "Recom-
mended fluids/lubricants and capacities"
in the "10. Technical information" section
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) or
similar equipment even if the other two
wheels are raised off the ground. Make sure that you inform the test facility
personnel that your vehicle is equipped
with 4WD before it is placed on a dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.

vehicle at high speeds until the brakes func-
tion correctly.
Driving uphill
When starting on a steep gradient, it is some-
times difficult to operate the brake. Use the
parking brake to hold the vehicle. When ready
to start, make sure that the shift lever is in an
appropriate forward or reverse driving posi-
tion, release the parking brake while depress-
ing the accelerator pedal. If your vehicle has
an electric parking brake, this will automati-
cally release when you depress the accelera-
tor pedal (DCT models).
Driving downhill
The engine braking action is effective for
controlling the vehicle while descending hills.
A low gear position in the manual shift mode,
low enough to obtain sufficient engine brak-
ing, should be selected.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced, in
order to assure the best braking perfor-
mance.This procedure is described in the vehicle ser-
vice manual and can be performed by an
INFINITI retailer.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
The Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot prevent
accidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking on
slippery surfaces. Remember that stopping
distances on slippery surfaces will be lon-
ger than on normal surfaces even with
ABS. Stopping distances may also be lon-
ger on rough, gravel or snow covered
roads, or if you are using tire chains. Al-
ways maintain a safe distance from the ve-
hicle in front of you. Ultimately, the driver
is responsible for safety.
Tire type and condition may also affect
braking effectiveness.
– When replacing tires, install the specified
size of tires on all four wheels.
– When installing a replacement tire, make
sure that it is the proper size and type as
specified on the tire and loading informa- tion label. (See "Wheels and Tires" in the
"9. Maintenance and Schedules" section.)
– For detailed information, see "Wheels and
tires" in the "8. Do-it-yourself" section.
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during
hard braking or when braking on slippery sur-
faces. The system detects the rotation speed
at each wheel and varies the brake fluid pres-
sure to prevent each wheel from locking and
sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain
steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
Using system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid ob-
stacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.

socket can cause damage to the spark
plugs. It is recommended that you visit an INFINITI
retailer if checking or replacement is required.
WARNING
•Operating the engine with the air
cleaner filter off can cause you or others
to be burned. The air cleaner filter not
only cleans the intake air, it also stops
the flame if the engine backfires. If the
air cleaner is not installed and the engine
backfires, you could be burned. Never
drive with the air cleaner filter off. Be
cautious working on the engine when
the air cleaner is off.
•Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
CLEANING
If the windshield or rear window is not clear
after using the window washer or if a wiper
blade chatters when running, wax or other
material may be on the blade or windshield.
Clean the outside of the windshield or rear
window with a washer solution or a mild
detergent. The windshield or rear window is
clean if beads do not form when rinsing with
clear water.
Clean the blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
the windshield or rear window is still not clear
after cleaning the blades and using the wiper,
replace the blades.

TIRE ROTATION
INFINITI recommends rotating the tires ev-
ery 5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer to "Flat tire" in the "6. In
case of emergency" section.As soon as pos-
sible, tighten the wheel nuts to the specified
torque with a torque wrench.
Wheel nut tightening torque: 96 ft-lb (130
N·m)
The wheel nuts must be kept tightened to
specifications at all times. It is recommended
that wheel nuts be tightened to specification
at each tire rotation interval.
WARNING
•After rotating the tires, check and ad-
just the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding
tires, refer to "Important Tire Safety In-
formation" (US) or "Tire Safety Infor-
mation" in the Warranty Information
Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even
if it has been repaired. Such wheels or tires
could have structural damage and could
fail without warning.
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. (See "Wheels and Tires" in
the "9. Maintenance and Schedules" section
for recommended types and sizes of tires and
wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to de-
creased braking efficiency and/or early brake
pad/shoe wear.
Confirm the following for the TPMS:
WARNING
•The use of tires other than those recom-
mended or the mixed use of tires of dif-
ferent brands, construction (bias, bias-
belted or radial), or tread patterns can
adversely affect the ride, braking, han-
dling, VDC system, ground clearance,
body-to-tire clearance, tire chain clear-
ance, speedometer calibration, head-
light aim and bumper height. Some of
these effects may lead to accidents and
could result in serious personal injury.
•For 2WD models, if your vehicle was
originally equipped with 4 tires that
were the same size and you are only re-
placing 2 of the 4 tires, install the new
tires on the rear axle. Placing new tires
on the front axle may cause loss of ve-
hicle control in some driving conditions
and cause an accident and personal in-
jury.
•If the wheels are changed for any rea-
son, always replace with wheels which
have the same offset dimension. Wheels
of a different offset could cause prema-
ture tire wear, degrade vehicle handling
characteristics, affect the VDC system
and/or interference with the brake
discs. Such interference can lead to de-
creased braking efficiency and/or early
