WARNING
∙ When the power steering warning lightilluminates with the engine running, the
power assist for the steering will cease
operation. You will still have control of
the vehicle, but the steering will be
harder to operate.
∙ If wheels or tires other than the INFINITI recommended ones are used, Direct
Adaptive Steering® may not operate
properly and the power steering warning
light may illuminate.
∙ Do not modify the vehicle’s suspension parts such as shock absorbers, struts,
springs, stabilizer bars, bushings and
wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, Direct Adaptive Steering may not
operate properly and the power steering
warning light may illuminate.
∙ Do not modify the vehicle’s steering. If steering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, Direct Adaptive Steering
may not operate properly and the power
steering warning light may illuminate. ∙ If the Vehicle Dynamic Control (VDC)
OFF indicator light illuminates, the
power steering warning light may also il-
luminate at the same time. Stop the ve-
hicle in a safe location, turn the engine off
and restart the engine. If the power
steering warning light continues to illu-
minate, have the system checked. It is
recommended that you visit an INFINITI
retailer for this service. For additional in-
formation, refer to “Vehicle Dynamic
Control (VDC) system” in this section.
CAUTION
∙ Do not place the ignition switch in the ONposition while the steering wheel or a tire
is removed.
∙ Do not turn the steering wheel as much as possible while the ignition switch is any
position other than the ON position.
∙ Installing an accessory on the steering wheel, or changing the steering wheel,
may reduce the steering performance.
Direct Adaptive Steering is designed to con-
trol the steering force and steering angle ac-
cording to the vehicle speed and amount of
turning of the steering wheel. The steering characteristic can be selected
using the INFINITI Drive Mode Selector. For
additional information, refer to “INFINITI
Drive Mode Selector” in this section.
If the VDC system is turned off, the setting of
steering becomes Standard mode.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate that Direct Adaptive Steering is not
functioning properly and may need servicing.
Have the system checked. It is recommended
that you visit an INFINITI retailer for this
service. For additional information, refer to
“Power steering warning light” in the “Instru-
ments and Controls” section of the manual.
When the power steering warning light illu-
minates with the engine running, the power
assist for the steering will cease operation.
You will still have control of the vehicle. How-
ever, greater steering effort will be needed,
especially in sharp turns and at low speeds.
If Direct Adaptive Steering is malfunctioning,
the steering wheel may turn slightly even
when driving on a straight road.

∙ 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
the
indicator 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 the
andindicator lights
may illuminate. Do not drive on these
types of roads.
∙ When driving on an unstable surface such as a turntable, ferry, elevator or ramp,
the
indicator light may flash or
both the
andindicator lights
may illuminate. This is not a malfunction.
Restart the engine after driving onto a
stable surface. ∙ If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the
indicator light may flash or
both the
andindicator lights
may illuminate.
∙ The VDC system is not a substitute for winter tires or tire chains on a snow cov-
ered road. 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
This system senses driving based on the driv-
er’s steering and acceleration/braking pat-
terns, and controls brake pressure at indi-
vidual wheels to help smooth vehicle
response.
When the lower display is used to turn off the
Vehicle Dynamic Control system, the Active
Trace Control system is also turned off.
If the Active Trace Control is not functioning
properly, the FEB with Pedestrian Detection
system warning indicator light illuminates in
the instrument panel.
The Active Trace Control can be set to on
(enabled) or off (disabled) through the lower
display “Infiniti Drive Mode Selector” menu
option.
CHASSIS CONTROL
5-184Starting and driving

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 enhances brak-
ing feel by adding subtle deceleration with
CVT gear ratio control according to the driv-
er’s brake pedal operation
The Active Engine Brake can be set to on
(enabled) or off (disabled) through the lower
display “Infiniti Drive Mode Selector” menu
option.When the Active Engine Brake is operated at
corners and the “Chassis Control” mode is
selected in the lower display, the Active En-
gine Brake graphics are shown in the vehicle
information display.
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.

Two-Wheel Drive models with
Continuously Variable Transmission
(CVT)
INFINITI recommends that your vehicle be
towed with the driving (front) wheels off the
ground or place the vehicle on a flatbed truck
as illustrated.NOTE:
If the electronic parking brake is released,
the rear wheels can be grounded while tow-
ing. If the electronic parking brake is not re-
leased, towing dollies should be used. For
additional information, refer to “Electronic
parking brake” in the “Starting and driving”
section of this manual.
CAUTION
∙ Never tow Continuously Variable Trans-
mission (CVT) models with the front
wheels on the ground or four wheels on
the ground (forward or backward), as
this may cause serious and expensive
damage to the transmission. If it is neces-
sary to tow the vehicle with the rear
wheels raised always use towing dollies
under the front wheels.
∙ When towing Continuously Variable Transmission (CVT) models with the rear
wheels on the ground or on towing
dollies:
– Place the ignition switch in the OFF position, and secure the steering
wheel in a straight-ahead position

FLOOR MATS (if so equipped)
WARNING
To avoid potential pedal interference that
may result in a collision, injury or death:
∙ NEVER place a floor mat on top of an-other floor mat in the driver front posi-
tion or install them upside down or
backwards.
∙ Use only Genuine INFINITI floor mats or equivalent floor mats, specifically de-
signed for use in your vehicle model and
model year. ∙ Properly position the mats in the floor-
well using the floor mat positioning hook.
For additional information, refer to
"Floor mat installation" in this section.
∙ Make sure the floor mat does not inter- fere with pedal operation.
∙ Periodically check the floor mats to make sure they are properly installed.
∙ After cleaning the vehicle interior, check the floor mats to make sure they are
properly installed.
The use of Genuine INFINITI floor mats can
extend the life of your vehicle carpet and
make it easier to clean the interior. Mats
should be maintained with regular cleaning
and replaced if they become excessively
worn.Floor mat installation
Your vehicle is equipped with floor mat re-
tainer clips. The number and shape of the
floor mat retainer clips for each seating posi-
tion varies depending on the vehicle. When installing Genuine INFINITI floor mats,
follow the installation instructions provided
with the mat and the following:
1. With the ignition in the OFF position, the shift lever in P (Park) position and with
the parking brake fully applied, position
the floor mat in the floorwell so that the
floor mat grommet holes are aligned
with the retainer clips.
2. Secure the grommet holes into the clips and ensure that the floor mat is properly
positioned.
3. Make sure the floor mat does not inter- fere with pedal operation. With the igni-
tion still in the OFF position, the shift
lever in the P (Park) position and with the
parking brake applied, fully apply and
release all pedals. The floor mat must not
interfere with pedal operation or prevent
the pedal from returning to its normal
position.
It is recommended that you visit an INFINITI
retailer for details about installing the floor
mats in your vehicle.

7-6Appearance and care

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
∙ Park the vehicle on a level surface, applythe parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Move the shift lever to P (Park).
∙ Be sure the ignition switch is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine running, keep your hands, clothing, hair and tools
away from moving fans, belts and any
other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position and
the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
∙ If you must run the engine in an enclosed space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is necessary
to work under the vehicle, support it with
safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ Because the fuel lines on gasoline engine models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
CAUTION
∙ Do not work under the hood while theengine is hot. Turn the engine off and
wait until it cools down. ∙ Avoid contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid.
∙ Never leave the engine or Continuously Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
∙ Never connect or disconnect the battery or any transistorized component while
the ignition switch is in the ON position.

culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

If the brakes do not operate properly, it is
recommended that you have the brakes
checked. It is recommended that you visit an
INFINITI retailer for this service.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is applied.
WARNING
Have your brake system checked if the
brake pedal height does not return to nor-
mal. It is recommended that you visit an
INFINITI retailer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched scraping
or screeching sound will be heard when the
vehicle is in motion. The noise will be heard
whether or not the brake pedal is depressed.
Have the brakes checked as soon as possible
if the wear indicator sound is heard.Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does
not affect the function or performance of the
brake system.
Proper brake inspection intervals should be
followed.
For additional information regard-
ing brake inspections, refer to the appropri-
ate maintenance schedule information in the
"Maintenance and schedules" section of this
manual.

TYPES OF TIRES
WARNING
∙When changing or replacing tires, be sure
all four tires are of the same type (i.e.,
Summer, All Season or Snow) and con-
struction. An INFINITI retailer may be able
to help you with information about tire
type, size, speed rating and availability.
∙ Replacement tires may have a lower speed rating than the factory equipped
tires, and may not match the potential
maximum vehicle speed. Never exceed
the maximum speed rating of the tire.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the low tire pressure
warning system.
∙
Always use tires of the same type, size,
brand, construction and tread pattern on
all four wheels. Failure to do so may result
in a circumference difference between
tires on the front and rear axles which can
cause the Vehicle Dynamic Control (VDC)
system to malfunction resulting in per-
sonal injury or death, excessive tire wear
and may damage the transmission, trans-
fer case and differential gears.
∙ For additional information regarding tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
All-Wheel Drive (AWD) models
CAUTION
∙ ONLY use spare tires specified for the AWD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
that you visit an INFINITI retailer for this
service.
All season tires
INFINITI specifies All Season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
Season tires are identified by ALL SEASON
and/or M&S on the tire sidewall. Snow tires
have better snow traction than All Season
tires and may be more appropriate in some
areas.
