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 tem-
perature 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 oper-
ate).
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 down-
shift 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 tempera-
ture 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. It is recommended
you 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. It is recommended
you visit an INFINITI retailer for this service.
See “Warning lights, indicator lights and
audible reminders” (P.2-11).
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” (P.6-14).
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 cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.

through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.

WARNING
Failure to follow the warnings and
instructions for proper use of the LDW
and LDP (if so equipped) systems could
result in serious personal injury or death.
.The LDW and LDP (if so equipped)
systems will not steer the vehicle or
prevent loss of control. It is the
driver’s responsibility to stay alert,
drive safely, keep the vehicle in the
traveling lane, and be in control of
the vehicle at all times.
. The LDP system (if so equipped) may
activate if you change lanes without
first activating your turn signal or,
for example, if a construction zone
directs traffic to cross an existing
lane marker. If this occurs, you may
need to apply corrective steering to
complete your lane change.
. Because the LDP system (if so
equipped) may not activate under
the road, weather, and lane marker
conditions described in this section, it
may not activate every time your
vehicle begins to leave its lane and
you will need to apply corrective
steering.
