2018 INFINITI Q50 HYBRID child seat

3-4Pre-driving checks and adjustments
WARNING
.Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from unintention-
ally opening the doors, and will help
keep out intruders.
. Before opening any door, always look
for and avoid oncoming traffic.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets
unattended in your vehicle. Addition-
ally, the temperature inside a closed
vehicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.

LOCKING WITH MECHANICAL
KEY
The power door lock system allows you to
lock or unlock all doors and trunk lid
simultaneously using the mechanical key.
.Turning the driver’s door key cylinder to
the front of the vehicle
will lock all
doors and trunk lid.
. Turning the driver’s door key cylinder
once to the rear of the vehicle
will
unlock the driver’s door. After returning
the key to the neutral position
, turning
it to the rear again within 60 seconds will
unlock all doors. .
You can switch the lock system to the
mode that allows you to open all the
doors and trunk lid when the key is
turned once. (See the Infiniti InTouch
Owner’s Manual for details.)
OPENING AND CLOSING WIN-
DOWS WITH MECHANICAL KEY
The driver’s door key operation also allows
you to open and close the window that is
equipped with the automatic open/close
function. (See “Power windows” (P.2-52).)
To open the window, turn the driver’s door
key cylinder to the rear of the vehicle for
longer than 1 second. The door is unlocked
and the window keeps opening while turning
the key.
This function can also be performed by
pushing and holding the UNLOCK button
on the Intelligent Key. (See “Remote keyless
entry system” (P.3-15).)
To close the window, turn the driver’s door
key cylinder to the front of the vehicle for
longer than 1 second. The door is locked and
the window keeps closing while turning the
key.
DOORS

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.
