Infiniti QX: Engine protection mode
The engine has an engine protection mode
to reduce the chance of damage if the
coolant temperature becomes too high (for
example, when climbing steep grades in
high temperature with heavy loads, such
as when towing a trailer).
When the engine temperature reaches a
certain level:
► The engine coolant temperature gauge
will move toward the H position.
► Engine power may be reduced.
► The air conditioning cooling function
may be automatically turned OFF for a
short time (the blower will continue to
operate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator
pedal, but the vehicle may not accelerate
at the desired speed. The transmission will
downshift or upshift as it reaches prescribed
shift points. You can also shift
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accelerator
pedal, and air conditioning cooling function will automatically be turned back
ON.
If:
1. The engine coolant temperature is not
reduced.
2. The air conditioning cooling function
does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant
temperature gauge does not return to
the normal range from the H position,
this may indicate a malfunction. Move
the vehicle off the road to a safe area
and allow the engine to cool. If after
checking the oil and coolant, the
remains
on or engine coolant temperature
does not return to the normal
range, do not continue to drive and
contact an INFINITI retailer.
The Malfunction Indicator Light (MIL)
may also come ON. You do not need to
have your vehicle towed, unless it remains
on, but have it inspected soon by an
INFINITI retailer. See “Warning/indicator
lights and audible reminders” in the “2.
Instruments and controls” section.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced speed
may be lower than other traffic, which could
increase the chance of a collision. Be
especially careful when driving. If the
vehicle cannot maintain a safe driving
speed, pull to the side of the road in a safe
area. Allow the engine to cool and return to
normal operation. See “If your vehicle overheats”
in the “6. In case of emergency”
section.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not covered
by warranty. Turn off the engine as soon as
it is safe to do so.
