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.3-23), “Glove box” (P.2-
48) 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

Do not use excessive force.
9. Refill engine with recommended oil and install the oil filler cap securely.
See “Capacities and recommended
fluids/lubricants” (P.10-2) for drain and
refill capacity. The drain and refill capa-
city depends on the oil temperature and
drain time. Use these specifications for
reference only. Always use the dipstick
to determine the proper amount of oil in
the engine.
10. Start the engine and check for leakage around the drain plug and the oil filter.
Correct as required.
11. Turn the engine off and wait more than 15 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
After the operation
1. Install the engine undercover into posi-tion as the following steps.
a. Pull the center of the small plastic clip
out.
b. Hold the engine undercover into posi- tion.
c. Insert the clip through the undercover into the hole in the frame, then push
the center of the clip in to lock the clip
in place. d. Install the other bolts that hold the
undercover in place. Be careful not to
strip the bolts or over-tighten them.
2. Lower the vehicle carefully to the ground.
3. Dispose of waste oil and filter properly.
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 may cause deterioration in dri-
veability and automatic transmission
durability, and may damage the
automatic transmission. Damage
caused by the use of fluid other than
as recommended is not covered by
the INFINITI new vehicle limited
warranty.
