water pump INFINITI QX50 2020 Owner's Manual

∙ Use only an original equipment type fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emission
control system. An incorrect cap can re-
sult in a serious malfunction and possible
injury. It could also cause the
Mal-
function Indicator Light (MIL) to come
on.
∙ Never pour fuel into the throttle body to attempt to start your vehicle.
∙ Do not fill a portable fuel container in the vehicle or trailer. Static electricity can
cause an explosion of flammable liquid,
vapor or gas in any vehicle or trailer. To
reduce the risk of serious injury or death
when filling portable fuel containers:
– Always place the container on the ground when filling.
– Do not use electronic devices when filling.
– Keep the pump nozzle in contact with the container while you are filling it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
∙ Do not use a fuel containing more than15% ethanol in your vehicle. For addi-
tional information, refer to “Fuel recom-
mendation” in the “Technical and con-
sumer information” section of this
manual.
∙ The Loose Fuel Cap warning message will be displayed if the fuel-filler cap is not
properly tightened. It may take a few
driving trips for the message to be dis-
played. Failure to tighten the fuel-filler
cap properly after the Loose Fuel Cap
warning is displayed may cause the Mal-
function Indicator Light (MIL) to
illuminate.
∙ Failure to tighten the fuel-filler cap prop- erly may cause the
Malfunction In-
dicator Light (MIL) to illuminate. If
the
light illuminates because the
fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive
the vehicle. The
light should turn
off after a few driving trips. If the
light does not turn off after a few driving
trips, have the vehicle inspected. It is rec-
ommended that you visit an INFINITI re-
tailer for this service. ∙ For additional information, refer to
“Malfunction Indicator Light (MIL)” in
the “Instruments and controls” section of
this manual.
∙ If fuel is spilled on the vehicle body, flush it away with water to avoid paint
damage.
NOTE:
Changing ignition switch status during the
refueling process may cause a delay in fuel
gauge response.

CAUTION
∙ Continuously Variable Transmission(CVT) models cannot be push-started or
tow-started. Attempting to do so may
cause transmission damage.
∙ Do not push start this vehicle. The three- way catalyst may be damaged.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause engine
damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the coolant reservoir cap
while the engine is still hot. When the
coolant reservoir cap is removed, pres-
surized hot water will spurt out, possibly
causing serious injury.
∙ Do not open the hood if steam is coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc. take the following steps. 1. Move the vehicle safely off the road, apply the parking brake and engage the
P (Park) position.
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. (If
steam or coolant is escaping, turn off the
engine.) Do not open the hood further
until no steam or coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing, the water pump belt is missing or
loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling fan
can start at any time.

CAUTION
∙ Do not ground accessories directly to thebattery terminal. Doing so will bypass the
variable voltage control system and the
vehicle battery may not charge
completely.
∙ Use electrical accessories with the engine running to avoid discharging the vehicle
battery.
Your vehicle is equipped with a variable volt-
age control system. This system measures
the amount of electrical discharge from the
battery and controls voltage generated by
the generator. The current sensor
Ais located near the
battery along the negative battery cable. If
you add electrical accessories to your vehicle,
be sure to ground them to a suitable body
ground such as the frame or engine block
area.
