• Keep your engine tuned up.
• Follow the recommended scheduledmaintenance.
• Keep the tires inflated to the correct pres- sure. Low tire pressure increases tire wear
and lowers fuel economy.
• Keep all the wheels in correct alignment. Improper alignment increases tire wear and
lowers fuel economy.
• Use the recommended viscosity engine oil. For additional information, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2).
If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.
If the AWD error warning message is dis-
played, there may be a malfunction in the
Intelligent AWD system. Reduce vehicle
speed and have your vehicle checked as soon
as possible. It is recommended that you visit
an INFINITI retailer for this service. The AWD high temperature message may be
displayed while trying to free a stuck vehicle
due to increased oil temperature. The driving
mode may change to 2-Wheel Drive (2WD).
If this message is displayed, stop the vehicle
with the engine idling, as soon as it is safe to
do so. Then if the message turns off, you can
continue driving.

The tire size message may be displayed if
there is a large difference between the diam-
eters of front and rear wheels. Pull off the
road in a safe area, with the engine idling.
Check that all tire sizes are the same, that the
tire pressure is correct and that the tires are
not excessively worn.
If any warning messages continue to be dis-
played, have your vehicle checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
• Do not drive beyond the performance ca-
pability of the tires. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control, even
with Intelligent 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 personal injury or
vehicle damage.
• 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 that you inform the
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 dam-
age or unexpected vehicle movement
which could result in serious personal in-
jury or vehicle damage.CAUTION
• Do not operate the engine on a free roller
when any of the wheels are raised.
• If you use the free roller, rotate four
wheels with the same speed without
raising any wheels.
• If an AWD warning message is displayed
while driving there may be a malfunction
in the AWD system. Reduce the vehicle
speed immediately and have your vehicle
checked as soon as possible. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
• The powertrain may be damaged if you
continue driving when the AWD tem-
perature or tire size incorrect messages
are displayed.
• If the AWD high temperature message is
displayed while you are driving, pull off
the road in a safe area, and idle the en-
gine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again.

5-134Starting and driving

• You may feel a pulsation in the brake pedaland hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
• Adjust your speed and driving to the road conditions.
For additional information, see “Slip indicator
light” (P. 2-17) and ”Vehicle Dynamic Control
(VDC) OFF indicator light” (P. 2-17).
If a malfunction occurs in the system, the
andindicator lights come on in the
instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.
The lower display is used to turn off the VDC
system. When the VDC system is turned off,
the
indicator light, the RAB system
warning light, and the FEB with Pedestrian
Detection system warning light illuminate to
indicate the VDC, FEB with Pedestrian De-
tection, and RAB systems are off.
When the lower display is used to turn off the
system, the VDC system still operates to pre-
vent one drive wheel from slipping by trans-
ferring power to a non-slipping drive wheel.
The
indicator light flashes if this occurs.
All other VDC functions are off and the
indicator light will not flash. The VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back to the ON position.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a clunk noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a
malfunction.
WARNING
• The VDC system is designed to help the
driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving tech-
niques. Reduce vehicle speed and be es-
pecially careful when driving and corner-
ing on slippery surfaces and always drive
carefully. •
Do not modify the vehicle's suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are ex-
tremely deteriorated, the VDC system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the
indicator light may
flash or both theandindicator
lights may illuminate.
• If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, the VDC system may not operate
properly and both the
and theindicator lights may illuminate.
• If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate.
• When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator light may flash or
both theandindicator lights
may illuminate. Do not drive on these
types of roads.
5-142Starting and driving

The chassis control is an electric control mod-
ule that includes the following functions:
• Active Trace Control
• Active Engine Brake
• Active Ride Control
ACTIVE TRACE CONTROL
The Active Trace Control senses driving
based on the driver’s steering and
acceleration/braking patterns, and controls
brake pressure at individual wheels to aid
tracing at corners and help smooth vehicle
response.
When the lower display is used to turn off the
VDC system, the Active Trace Control sys-
tem is also turned off.
When the PERSONAL mode is selected, the
Active Trace Control can be set to ON (en-
abled) or OFF (disabled). For additional infor-
mation, see “INFINITI Drive Mode Selector”
(P. 5-29).When the Active Trace Control is operated
and the “Chassis Control” mode is selected in
the vehicle information display, the Active
Trace Control graphics are shown in the ve-
hicle information display. For additional in-
formation, see “Vehicle information display”
(P. 2-19).
If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Trace Control is
not functioning properly. Have the system
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
WARNING
The Active Trace Control may not be effec-
tive depending on the driving condition. Al-
ways drive carefully and attentively.
When the Active Trace Control is operating,
you may feel a pulsation in the brake pedal
and hear a noise. This is normal and indicates
that the Active Trace Control is operating
properly.
You may also feel deceleration when the Ac-
tive Trace Control is operating. However, this
is not a malfunction.
LSD4774
CHASSIS CONTROL
5-144Starting and driving

Even if the Active Trace Control is set to OFF,
some functions will remain on to assist the
driver (for example: avoidance scenes).
ACTIVE ENGINE BRAKE
The Active Engine Brake function adds subtle
deceleration by controlling Continuously
Variable Transmission (CVT) gear ratio, de-
pending on the cornering condition calcu-
lated from the driver's steering input and plu-
ral sensors. This benefit is for easier
traceability and less workload of adjusting
speed with braking at corners.
The Active Engine Brake also adds subtle
deceleration with gear ratio control accord-
ing to driver’s brake pedal operation.
When the PERSONAL mode is selected, the
Active Engine Brake can be set to ON (en-
abled) or OFF (disabled). For additional infor-
mation, see “INFINITI Drive Mode Selector”
(P. 5-29).
When the lower display is used to turn off the
VDC system, the Active Engine Brake system
is also turned off.When the Active Engine Brake is operated at
corners and the “Chassis Control” mode is
selected in the vehicle information display,
the Active Engine Brake graphics are shown
in the vehicle information display. For addi-
tional information, see “Vehicle information
display” (P. 2-19).
If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Engine Brake is
not functioning properly. Have the system
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
WARNING
The Active Engine Brake may not be effec-
tive depending on the driving condition. Al-
ways drive carefully and attentively.
When the Active Engine Brake is operating,
the needle of the tachometer will rise up and
you may hear an engine noise. This is normal
and indicates that the Active Engine Brake is
operating properly.
You may also feel deceleration when the Ac-
tive Engine Brake is operating. However, this
is not a malfunction.
LSD4774
Starting and driving5-145

ACTIVE RIDE CONTROL
This system senses upper body motion
(based on wheel speed information) and con-
trols four wheel brake pressure. This will en-
hance ride comfort in effort to restrain un-
comfortable upper body movement when
passing over undulated road surfaces.
When the lower display is used to turn off the
VDC system, the Active Ride Control is also
turned off.
When the Active Ride Control is operated
and the “Chassis Control” mode is selected in
the vehicle information display, the Active
Ride Control graphics are shown in the ve-
hicle information display. For additional in-
formation, see “Vehicle information display”
(P. 2-19).If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Ride Control is
not functioning properly. Have the system
checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for
this service.
When the Active Ride Control is operating,
you may hear noise and sense slight decel-
eration. This is normal and indicates that the
Active Ride Control is operating properly.
WARNING
• Never rely solely on the hill start assist
system to prevent the vehicle from mov-
ing backward on a hill. Always drive
carefully and attentively. Depress the
brake pedal when the vehicle is stopped
on a steep hill. Be especially careful when
stopped on a hill on frozen or muddy
roads. Failure to prevent the vehicle
from rolling backwards may result in a
loss of control of the vehicle and possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a standstill
on a hill. Depress the brake pedal when
the vehicle is stopped on a steep hill. Fail-
ure to do so may cause the vehicle to roll
backwards and may result in a collision or
serious personal injury.
• The hill start assist system may not pre-
vent the vehicle from rolling backwards
on a hill under all load or road conditions.
Always be prepared to depress the brake
pedal to prevent the vehicle from rolling
backwards. Failure to do so may result in
a collision or serious personal injury.
LSD3922
HILL START ASSIST SYSTEM
5-146Starting and driving

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:
• The transmission is shifted to a forward orreverse gear.
• The vehicle is stopped completely on a hill by applying the brake. The maximum hold-
ing time is 2 seconds. After 2 seconds the
vehicle will begin to roll back and the hill
start assist system will stop operating
completely.
The hill start assist system will not operate
when the shift lever is placed in the N (Neu-
tral), the Park button is pressed to place the
vehicle in the P (Park) position or on a flat and
level road.
The Hill Start Assist function status can be
checked in the “Chassis Control” mode in the
vehicle information display. For additional in-
formation, see “Vehicle information display”
(P. 2-19). The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
When the sonar system is turned on, the
sonar view will automatically appear in the
touch screen display when the camera is
activated.
WARNING
• The sonar system is a convenience but it
is not a substitute for proper parking.
• The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
LSD4775LSD2993
FRONT AND REAR SONAR SYSTEM
(if so equipped)
Starting and driving5-147

•Read and understand the limitations of
the sonar system as contained in this
section. The colors of the sonar indicator
indicates different distances to the
object.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
• The sonar system is designed as an aid to
the driver in detecting large stationary
objects to help avoid damaging the
vehicle.
• The sonar system is not designed to pre-
vent contact with small or moving ob-
ject. Always move slowly. The system
will not detect small objects below the
bumper, and may not detect objects
close to the bumper or on the ground.
• The sonar system may not detect the fol-
lowing objects: fluffy objects such as
snow, cloth, cotton, glass-wool, etc.;
thin objects such as rope, wire and chain,
etc.; or wedge-shaped objects.CAUTION
• Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
• The front and rear sonar detect the dis-
tance between the vehicle and the ob-
stacle by detecting the sound wave re-
flected from the surface of an obstacle.
When there is a sound such as horn, or an
ultrasonic source (such as sonar of other
vehicles) around the vehicle, the sonar
may not detect objects properly.
• Keep the sonar sensors (located on the
bumper fascia) free from snow, ice and
large accumulations of dirt. Do not clean
the sonar with sharp objects. If the sen-
sors are covered, the accuracy of the so-
nar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever
is in the D (Drive) position and both front and
rear obstacles when the shift lever is in the R
(Reverse) position. Sonar Operation Table

The system is deactivated at speeds above 6
mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3 sec-
onds when an obstacle is detected by only
the corner sensor and the distance does not
change. The tone will stop when the obstacle
get away from the vehicle.
When the object is detected, the indicator
(green) appears and blinks and the tone
sounds intermittently. When the vehicle
moves closer to the object, the color of the
indicator turns yellow and the rate of the
blinking increases. When the vehicle is very
close to the object, the indicator stops blink-
ing and turns red, and the tone sounds
continuously.
