display INFINITI QX50 2019 Owners Manual

Frequently check the tire pressure and adjust
pressure of each tire properly. The tire pres-
sure can be also checked in the vehicle infor-
mation display.
It can be difficult to tell if a run-flat tire is
under-inflated or flat. Check the tire pres-
sures as described in this section. If the tire
becomes under-inflated while driving, the
low tire pressure warning light will illuminate
and the “Tire Pressure Low – Add Air” warn-
ing appears in the vehicle information display.
If the tire becomes flat while driving, the low
tire pressure warning light and the “Flat Tire –
Visit dealer" warning will appear.
Low tire pressure:
If the vehicle is being driven with low tire
pressure, the low tire pressure warning light
will illuminate and the “Tire Pressure Low –
Add Air” warning appears in the vehicle infor-
mation display.
Flat tire:
If the vehicle is being driven with one or more
flat tires, the low tire pressure warning light
will illuminate continuously and a chime will
sound for 10 seconds. A “Flat-Tire – Visit
dealer" warning also appears in the vehicle
information display.The chime will only sound at the first indica-
tion of a flat tire and the warning light will
illuminate continuously. When the flat tire
warning is activated, have the system reset
and the tire checked and replaced if neces-
sary. It is recommended that you visit an
INFINITI retailer for this service. Even if the
tire is inflated to the specified COLD tire
pressure, the warning light will continue to
illuminate until the system is reset. It is recom-
mended that you visit an INFINITI retailer for
this service.
If the low tire pressure warning light illumi-
nates continuously and the “Flat Tire – Visit
dealer" warning appears in the vehicle infor-
mation display:
∙ Do not exceed 50 mph (80 km/h).
∙ Increase your following distance to allow for increased stopping distances.
∙ Avoid sudden maneuvers, hard cornering and hard braking.WARNING
∙ Although you can continue driving with apunctured run-flat tire, remember that
vehicle handling stability is reduced,
which could lead to an accident and per-
sonal injury. Also, driving a long distance
at high speeds may damage the tire.
∙ Do not drive at speeds above 50 mph (80 km/h) and do not drive more than
approximately 93 miles (150 km) with a
punctured run-flat tire. The actual dis-
tance the vehicle can be driven on a flat
tire depends on outside temperature, ve-
hicle load, read conditions and other
factors.
∙ Drive safely at reduced speeds. Avoid hard cornering or braking, which may
cause you to lose control of the vehicle.
∙ If you detect any unusual sounds or vi- brations while driving with a punctured
run-flat tire, pull off the road to a safe
location and stop the vehicle as soon as
possible. The tire may be seriously dam-
aged and need to be replaced.

NOTE:
(1) After 30,000 miles (48,000 km) or 48 months, inspect every 7,500 miles (12,000 km) or 12 months. Replace the drive belts if found
damaged.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Periodic maintenance is not required.
(4) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles
(120,000 km) or 60 months.
(5) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50%
demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy of the
factory fill coolant.
(6) If the oil replacement indicator is displayed, change the engine oil and filter within two weeks or less than 500 miles (800 km)
(7) Replace spark plug when the plug gap exceeds 0.045 in (1.15 mm) even if within specified periodic replacement mileage.
(8) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI for reliable vehicle operation. The owner need not perform such
maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are required.
9-10Maintenance and schedules

When planning to drive your INFINITI ve-
hicle in another country,you should first find
out if the fuel available is suitable for your
vehicle's engine.
Using fuel with an octane rating that is too
low may cause engine damage. All gasoline
vehicles must be operated with unleaded
gasoline. Therefore, avoid taking your vehicle
to areas where appropriate fuel is not avail-
able.
When transferring the registration of your
vehicle to another country, state, province
or district, it may be necessary to modify the
vehicle to meet local laws and regulations.
The laws and regulations for motor vehicle
emission control and safety standards vary
according to the country, state, province or
district; therefore, vehicle specifications may
differ.
When any vehicle is to be taken into another
country, state, province or district and reg-
istered, its modifications, transportation,
and registration are the responsibility of the
user. INFINITI is not responsible for any in-
convenience that may result.
