states for emissions testing), or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with 4WD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury (4WD
models).
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
. Accelerating quickly, sharp steering
maneuvers or sudden braking may cause
loss of control.
. If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your vehicle has a higher center of
gravity than a conventional passenger
car. The vehicle is not designed for
cornering at the same speeds as con-
ventional passenger cars. Failure to
operate this vehicle correctly could
result in loss of control and/or a rollover
accident.
. Always use tires of the same type, size, brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
. Be sure to check the brakes immediately
after driving in mud or water. See “Brake
system” later in this section for wet
brakes.
. Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or sideways,
you could be injured.
. Whenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See the maintenance
information in the “INFINITI Service and
Maintenance Guide”.
. Spinning the rear wheels on slippery
surfaces may cause the 4WD warning
light to flash. The 4WD system may also
automatically switch from the 4WD
mode to the 2WD mode. This could
reduce traction. Be especially careful
when towing a trailer (4WD models).WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (The engine will stop when the
ignition switch is pushed 3 consecutive
times or the ignition switch is pushed and
held for more than 2 seconds.) If the engine
stops while the vehicle is being driven, this
could lead to a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the shift lever to
the P (Park) position.

4. Push the ignition switch while depres-sing the brake pedal within 10 seconds
after the chime sounds. The engine will
start.
After step 3 is performed, when the
ignition switch is pushed without depres-
sing the brake pedal, the ignition switch
position will change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears on the dot matrix liquid
crystal display even if the Intelligent
Key is inside the vehicle. This is not a
malfunction. To turn off the Intelligent
Key battery discharge indicator, touch
the ignition switch with the Intelligent
Key again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery
as soon as possible. (See “Battery”in
the “8. Maintenance and do-it-your-
self” section.) .
Make sure the area around the vehicle
is clear.
. Check fluid levels such as engine oil,
coolant, brake fluid and window
washer fluid as frequently as possible,
or at least whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints/headrests.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to
the ON position. (See “Warning/indica-
tor lights and audible reminders” in the
“2. Instruments and controls” section.)1. Apply the parking brake.
2. Move the shift lever to the P (Park) or N
(Neutral) position. (P is recommended.)
The starter is designed not to operate
unless the shift lever is in either of the
above positions.
3. Push the ignition switch to the ON position. Depress the brake pedal and
push the ignition switch to start the
engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the

restarting, depress the accelerator
pedal a little (approximately 1/3 to
the floor) and while holding, crank
the engine. Release the accelerator
pedal when the engine starts.
.If the engine is very hard to startbecause it is flooded, depress the
accelerator pedal all the way to the
floor and hold it. Push the ignition
switch to the ON position to start
cranking the engine. After 5 or 6
seconds, stop cranking by pushing
the ignition switch to OFF. After
BEFORE STARTING THE ENGINE STARTING THE ENGINE

cranking the engine, release the
accelerator pedal. Crank the engine
with your foot off the accelerator
pedalby depressing the brake pedal
and pushing the push-button igni-
tion switch to start the engine. If the
engine starts, but fails to run, repeat
the above procedure.
CAUTION
Do not operate the starter for more than 15
seconds at a time. If the engine does not
start, push the ignition switch to OFF and
wait 10 seconds before cranking again,
otherwise the starter could be damaged.
4. Warm-up
Allow the engine to idle for at least 30
seconds after starting. Do not race the
engine while warming it up. Drive at
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 - 3 minutes before
shutting it off. Starting and stopping
the engine over a short period of time
may make the vehicle more difficult to
start. When racing the engine up to 4,000
rpm or more under the no load condi-
tion, the engine will enter the fuel cut
mode.
5. To stop the engine, shift the shift lever to the P (Park) position and push the
ignition switch to the OFF position.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
REMOTE START (if so equipped)
Vehicles started with the remote engine
start function require the ignition switch to
be placed in the ON position before the
shift lever can be moved from the P (Park)
position. To place the ignition switch in the ON position, perform the following steps:
1. Make sure that the Intelligent Key is on
you.
2. Depress the brake pedal.
3. Push the ignition switch once to the ON position.
For additional information about the re-
mote engine start function, see “Remote
keyless entry system” in the“3. Pre-driving
checks and adjustments” section.

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 temperature 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
operate).
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
downshift or upshift as it reaches pre-
scribed shift points. You can also shift
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator 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
temperature 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 tempera-
ture does not return to the normal
range, do not continue to drive and
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 by an
INFINITI retailer. See “Warning/indicator
lights and audible reminders” in the“2.
Instruments and controls” section.
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 over-
heats” in the“6. In case of emergency”
section.
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 covered
by warranty. Turn off the engine as soon as
it is safe to do so.

LANE DEPARTURE PREVENTION
(LDP) SYSTEM
Precautions on LDP system
WARNING
.The LDP system 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 vehicle at all
times.
. The LDP system is primarily intended for
use on well-developed freeways or high-
ways. It may not detect the lane markers
in certain roads, weather or driving
conditions.
. Using the LDP system under some
conditions of road, lane marker or
weather, or when you change lanes
without using the lane change signal
could lead to an unexpected system
operation. In such conditions, you need
to correct the vehicle’s direction with
your steering operation to avoid acci-
dents. .
When the LDP system is operating, avoid
excessive or sudden steering maneu-
vers. Otherwise, you could lose control
of the vehicle.
. The LDP system will not operate at
speeds below approximately 45 MPH
(70 km/h) or if it cannot detect lane
markers.
. The LDP system may not function
properly under the following conditions,
and do not use the LDP system:
—During bad weather (rain, fog, snow,
wind, etc.).
—When driving on slippery roads,
such as on ice or snow, etc.
—When driving off-road such as on sand or rock, etc.
—When driving on winding or uneven
roads.
—When there is a lane closure due toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving without normal tireconditions (for example, tire wear, low tire pressure, installation of
spare tire, tire chains, non-standard
wheels).
—When the vehicle is equipped with
non-original brake parts or suspen-
sion parts.
—When towing a trailer or othervehicle.
. If the LDP system malfunctions, it will
cancel automatically. The lane departure
warning light (orange) on the instrument
panel will illuminate.
. If the lane departure warning light
(orange) illuminates, pull off the road
to a safe location and stop the vehicle.
Turn the engine off and restart the
engine. If the warning light (orange)
continues to illuminate, have the LDP
system checked by an INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
