LHA5275LHA5276
4-26Monitor, climate, audio, phone and voice recognition systems

Be attentive at all times, and avoid driving
when tired. Never drive when under the influ-
ence of alcohol or drugs (including prescrip-
tion or over-the-counter drugs which may
cause drowsiness). Always wear your seat
belt as outlined in the “Safety – Seats, seat
belts and supplemental restraint system” sec-
tion of this manual, and also instruct your
passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers.In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seat belt.
OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If
this occurs, maintain control of the vehicle by
following the procedure below. Please note
that this procedure is only a general guide.
The vehicle must be driven as appropriate
based on the conditions of the vehicle, road
and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course. 4. When appropriate, slowly release the ac-
celerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while vehicle
speed is reduced. Do not attempt to drive
the vehicle back onto the road surface
until vehicle speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to
the road surface. When all tires are on the
road surface, steer the vehicle to stay in
the appropriate driving lane.
• If you decide that it is not safe to return the vehicle to the road surface based on
vehicle, road or traffic conditions,
gradually slow the vehicle to a stop in a
safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged
due to hitting a curb or pothole. Rapid air
pressure loss can also be caused by driving on
under-inflated tires.
Rapid air pressure loss can affect the han-
dling and stability of the vehicle, especially at
highway speeds. Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspecting the tires for wear and damage. For
additional information, see “Wheels and tires”
(P. 8-27). If a tire rapidly loses air pressure or
“blows-out” while driving, maintain control of
the vehicle by following the procedure below.
Please note that this procedure is only a gen-
eral guide. The vehicle must be driven as ap-
propriate based on the conditions of the ve-
hicle, road and traffic.
WARNING
The following actions can increase the
chance of losing control of the vehicle if
there is a sudden loss of tire air pressure.
Losing control of the vehicle may cause a
collision and result in personal injury.
• The vehicle generally moves or pulls in
the direction of the flat tire.
• Do not rapidly apply the brakes.
• Do not rapidly release the accelerator
pedal.
• Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course.
Starting and driving5-9

•Stay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
• If your engine stalls or you cannot make
it to the top of a steep hill, never attempt
to turn around. Your vehicle could tip or
roll over. Always back straight down in R
(Reverse) gear and apply brakes to con-
trol your speed.
• Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
• Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
• Secure heavy loads in the cargo area as
far forward and as low as possible. Do
not equip the vehicle with tires larger
than specified in this manual. This could
cause your vehicle to roll over. •
Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move suddenly
and injure your hands. Instead drive with
your fingers and thumbs on the outside
of the rim.
• Before operating the vehicle, ensure that
the driver and all passengers have their
seat belts fastened.
• Always drive with the floor mats in place
as the floor may become hot.
• Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your INFINITI is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
• Do not drive beyond the performance ca-
pability of the tires, even with AWD
engaged.
• For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any drive or
reverse position with the engine running.
Doing so may result in drivetrain damage
or unexpected vehicle movement which
could result in serious vehicle damage or
personal injury. •
Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious vehicle dam-
age or personal injury.
• When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
• Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause
loss of control.
• If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds.
Your INFINITI vehicle has a higher center
of gravity than a passenger car. The ve-
hicle is not designed for cornering at the
same speeds as passenger cars. Failure
to operate this vehicle correctly could re-
sult in loss of control and/or a rollover
accident.
Starting and driving5-11

•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 front
wheels when driving on slippery roads
and drive carefully.
• Be sure to check the brakes immediately
after driving in mud or water. For addi-
tional information, see “Brake precau-
tions” (P. 5-152).
• 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. For additional information, see
“Additional maintenance items for se-
vere operating conditions” (P. 9-7).INTELLIGENT ALL-WHEEL

PRECAUTIONS (if so equipped)
WARNING
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
• 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 front
wheels when driving on slippery roads
and drive carefully.
• This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
• For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any D
(Drive) or R (Reverse) position with the
engine running. Doing so may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury. •
Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is

on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious vehicle dam-
age or personal injury.
• When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the LDP system
could result in serious injury or death.
• The LDP system will not steer the vehicle
or prevent loss of control. It is the driv-
er’s responsibility to stay alert, drive
safely, keep the vehicle in the traveling
lane, and be in control of the 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 road, weather, or driving
conditions.
The LDP system will operate when the ve-
hicle is driven at speeds of approximately 37
mph (60 km/h) and above, and only when the
lane markings are clearly visible on the road.
The LDP system warns the driver with a
warning indicator in the vehicle information
display, the steering wheel will vibrate and
helps assist the driver to return the vehicle to
the center of the traveling lane by applying
the brakes to the left or right wheels individu-
ally (for a short period of time).
The LDP system monitors the lane markers
on the traveling lane using the camera unit
O1
located above the inside mirror.
