5-4Starting and driving
WARNING
.Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
. Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
. If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
. Do not run the engine in closed spaces
such as a garage.
. Do not park the vehicle with the
INFINITI Direct Response Hybrid
®
System running for any extended
length of time.
. Keep the trunk lid closed while driv-
ing, otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the
trunk lid open, follow these precau-
tions:
1) Open all the windows.
2) Set the air recirculation mode to off and the fan control to high to
circulate the air. .
If electrical wiring or other cable
connections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer’s
recommendation to prevent carbon
monoxide entry into the vehicle.
. The exhaust system and body should
be inspected by a qualified mechanic
whenever:
— The vehicle is raised for service.
— You suspect that exhaust fumes are entering into the passenger
compartment.
— You notice a change in the sound of the exhaust system.
— You have had an accident invol- ving damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
