3-4Pre-driving checks and adjustments
CAUTION
Always carry the mechanical key in-
stalled in the key.
VALET HAND-OFF
When you have to leave a key with a valet,
give them the Intelligent Key itself and keep
the mechanical key with you to protect your
belongings.
To prevent the glove box and the trunk from
being opened during valet hand-off, follow
the procedures below.
1. Push the trunk release power cancelswitch to the OFF (cancel) side.
2. Remove the mechanical key from the Intelligent Key.
3. Lock the glove box and the trunk pass- through with the mechanical key.
4. Hand the Intelligent Key to the valet, keeping the mechanical key in your
pocket or bag for insertion into the
Intelligent Key when you retrieve your
vehicle.
See “Trunk lid” (P.3-22), “Glove box” (P.2-
47) and “Trunk pass-through” (P.1-7).
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.

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
engine 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 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.
PRECAUTIONS WHEN STARTING
AND DRIVING

5-20Starting and driving
5. Push the shift lever buttonand move
the shift lever to N (Neutral) position
while holding down the shift lock.
If the lever cannot be moved out of P (Park),
have the automatic transmission system
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
Adaptive Shift Control (ASC)
The adaptive shift control system automati-
cally operates when the transmission is in
the D (Drive) position and selects an appro-
priate gear depending on the road conditions
such as uphill, downhill or curving roads.
Control on uphill and curving roads:
A low gear is maintained that suits the
degree of the slope or curve to allow smooth
driving with a small number of shifts.
Control on downhill roads:
The adaptive shift control system shifts to a
low gear that suits the degree of the slope,
and uses the engine braking to reduce the
number of times that the brake must be
used.
Control on winding roads:
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel- erator pedal is depressed.
NOTE:
.
Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift to
a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by the
accelerator pedal when the vehicle is in
the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes main-
tains a lower gear for a longer period of
time than when adaptive shift control is
not operating. Engine speed will be
higher for a specific vehicle speed while
ASC system is operating than when ASC
is not operating.
WARNING
. Be sure the parking brake is fully
released before driving. Failure to do
so can cause brake failure and lead to
an accident.
. Do not release the parking brake
from outside the vehicle.
. Do not use the gear shift in place of
the parking brake. When parking, be
sure the parking brake is fully en-
gaged.
. To help avoid risk of injury or death
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.
PARKING BRAKE

Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the

WARNING
. Prolonged and repeated contact with
used engine oil may cause skin cancer.
. Try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with soap or hand cleaner
as soon as possible.
. Keep used engine oil out of reach of
children. When checking or replacement is required,
we recommend an INFINITI retailer for
servicing.
CAUTION
.
It is recommended that you use only
Genuine NISSAN Matic S ATF. Do
not mix with other fluids.
. Using automatic transmission fluid
other than Genuine NISSAN Matic S
ATF or equivalent may cause dete-
rioration in driveability and auto-
matic transmission durability, and
may damage the automatic transmis-
sion. Damage caused by the use of
fluid other than as recommended is
not covered by the INFINITI new
vehicle limited warranty.
