WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar function as
outlined in this section could result in seri-
ous injury or death.
∙ The sonar is a convenience feature. It is not a substitute for proper parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
∙ The driver is always responsible for safety during parking and other
maneuvers.
∙ Always look around and check that it is safe to move before parking.
∙ Read and understand the limitations of the sonar as contained in this section.
The sonar function helps to inform the driver
of large stationary objects around the vehicle
when parking by issuing an audible and visual
alert.

∙ The system may not detect the followingobjects:
– Fluffy objects such as snow, cloth, cotton, grass or wool.
– Thin objects such as rope, wire or chain.
– Wedge-shaped objects.
∙ If your vehicle sustains damage to the bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
jects or false alarms.
CAUTION
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
System temporarily unavailable
When the amber markers are displayed at the
corners of the vehicle icon and the function
cannot be activated from the Camera setting
menu (the setting items are grayed out), the
sonar system may be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (lo-
cated on the front and rear bumper fascia)
free from accumulations of snow, ice and
dirt. Do not scratch the surface of the sonar
sensors when cleaning. If the sensors are
covered, the accuracy of the sonar function
will be diminished.

– When there is dirt, water drops orsnow on the camera lens.
– When the position of the moving ob- jects in the display is not changed.
∙ The MOD system might detect flowing water droplets on the camera lens, white
smoke from the muffler, moving shad-
ows, etc.
∙ The MOD system may not function prop- erly depending on the speed, direction,
distance or shape of the moving objects.
∙ If your vehicle sustains damage to the parts where the camera is installed, leav-
ing it misaligned or bent, the sensing zone
may be altered and the MOD system may
not detect objects properly.
∙ When the temperature is extremely high or low, the screen may not display objects
clearly. This is not a malfunction. NOTE:
The blue or green MOD icon will change to
orange if one of the following has occurred:
∙ When the system is malfunctioning.
∙ When the component temperature reaches a high level (icon will blink).
∙ When the Rear View camera has de- tected a blockage (icon will blink).
If the icon light continues to illuminate or-
ange, have the MOD system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.

CAUTION
∙ Do not use leaded gasoline. Depositsfrom leaded gasoline will seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
∙ Keep your engine tuned up. Malfunctions in the ignition, fuel injection, or electrical
systems can cause over rich fuel flow into
the three-way catalyst, causing it to
overheat. Do not keep driving if the en-
gine misfires, or if noticeable loss of per-
formance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly. It is recommended
that you visit an INFINITI retailer for this
service.
∙ Avoid driving with an extremely low fuel level. Running out of fuel could cause the
engine to misfire, damaging the three-
way catalyst.
∙ Do not race the engine while warming it up.
∙ Do not push or tow your vehicle to start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label.
(If your vehicle has tires of a different size
than the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all your
tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability. Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to en-
sure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Starting and driving5-5

∙ Do not grip the inside or spokes of thesteering 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 affected
by strong side winds. Slower speeds en-
sure 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 dynamometer (such
as the dynamometers used by some
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 AWD 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.
∙ 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 vehicle
is not designed for cornering at the same
speeds as passenger cars. Failure to op-
erate 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 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, refer to “Brake pre-
cautions” in this section.
∙ 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, re-
fer to “Maintenance under severe oper-
ating conditions” in the “Maintenance
and schedules” section of this manual.
5-12Starting and driving

SYSTEM MAINTENANCE
The TSR system uses the same multi-sensing
front camera unit that is used by the Lane
Departure Warning (LDW) system, located in
front of the interior rearview mirror. For ad-
ditional information, refer to ”System mainte-
nance” in the “Lane Departure Warning
(LDW)” section.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the LDW system
could result in serious injury or death.
∙ This system is only a warning device toinform the driver of a potential unin-
tended lane departure. It 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 trav-
eling lane, and be in control of the vehicle
at all times. The LDW 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 LDW system monitors the lane markers
on the traveling lane using the camera unit
1
located above the inside mirror.
The LDW system warns the driver with an
indicator in the vehicle information display
and the steering wheel will vibrate, indicating
that the vehicle is beginning to leave the driv-
ing lane. For additional information, refer to
“LDW system operation” in this section.
