WARNING
∙ The electronic parking brake will not beautomatically applied when the engine is
stopped without using the ignition
switch (for example, by engine stalling).
Without the vehicle stationary, the elec-
tronic parking brake will not be auto-
matically applied even if the engine is
turned off with the ignition switch.
∙ Before leaving the vehicle, press the Park button to place the vehicle in the P (Park)
position and check that the electronic
parking brake indicator light (red) is illu-
minated to confirm that the electronic
parking brake is applied. The electronic
parking brake indicator light (red) will re-
main on for a period of time after the
driver’s door is locked.
CAUTION
When parking in an area where the outside
temperature is below 32°F (0°C), do not ap-
ply the parking brake to prevent it from
freezing.
For safe parking, place the shift lever in the
P (Park) position and securely block the
wheels. NOTE:
∙ If a malfunction occurs in the electronic
parking brake system (for example, due
to battery discharge), it is recommended
that you visit an INFINITI retailer.
∙ If the shift lever is moved to the P (Park)
position when the brake force is main-
tained by the automatic brake hold func-
tion, the electronic parking brake will
apply automatically.
∙ If the driver’s seat belt is unfastened
when the brake force is maintained by
the automatic brake hold function, the
electronic parking brake will apply auto-
matically.
∙ If the ignition switch is placed in the OFF
position when the brake force is main-
tained by the automatic brake hold func-
tion, the electronic parking brake will
apply automatically.
MANUAL OPERATION

leased. ∙
When pulling the electronic parking
brake switch up with the ignition switch
in the OFF or AUTO ACC position, the
parking brake switch indicator light will
continue to illuminate for a short period
of time.
WHEN TOWING A TRAILER
Depending on the weight of the vehicle and
trailer and the steepness of the slope, there
may be a tendency for the vehicle to move
backwards when starting from a standstill.
When this occurs, you can use the parking
brake switch in the same way as a conven-
tional lever type parking brake.
Before starting on sloping roads when tow-
ing a trailer, be sure to read the following to
prevent the vehicle from moving backwards
unintentionally.
∙ Release the parking brake switch as soon as the engine is delivering enough torque
to the wheels. The automatic brake hold function maintains
the braking force without the driver having to
depress the brake pedal when the vehicle is
stopped at a traffic light or intersection. As
soon as the driver depresses the accelerator
pedal again, the automatic brake hold func-
tion is deactivated and the braking force is
released. The operating status of the auto-
matic brake hold can be displayed on the
vehicle information display.
WARNING
∙ The automatic brake hold function is not
designed to hold the vehicle on a steep hill
or slippery road. Never use the automatic
brake hold when the vehicle is stopped on
a steep hill or slippery road. Failure to do
so may cause the vehicle to move.
∙ When the automatic brake hold function is activated but fails to maintain the ve-
hicle at a standstill, depress the brake
pedal to stop the vehicle. If the vehicle
unexpectedly moves due to outside con-
ditions, the chime may sound and auto-
matic brake hold warning may illuminate

TYPE
WARNING
∙ If the engine is not running or is turned offwhile driving, the power assist for the
steering will not work. Steering will be
harder to operate.
∙ When the power steering warning light illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of the
vehicle, but the steering will be harder to
operate. Have the power steering system
checked. It is recommended that you visit
an INFINITI retailer for this service.
The power steering system is designed to
provide power assist while driving to operate
the steering wheel with light force.
When the steering wheel is operated repeat-
edly or continuously while parking or driving
at a very low speed, the power assist for the
steering wheel will be reduced. This is to pre-
vent overheating of the power steering sys-
tem and protect it from getting damaged.
While the power assist is reduced, steering
wheel operation will become heavy. When
the temperature of the power steering sys-
tem goes down, the power assist level will return to normal. Avoid repeating such steer-
ing wheel operations that could cause the
power steering system to overheat.
You may hear a sound when the steering
wheel is operated quickly. However, this is
not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may indi-
cate the power steering system is not func-
tioning properly and may need servicing.
Have the power steering system checked. It is
recommended that you visit an INFINITI re-
tailer for this service.
When the power steering warning light illu-
minates with the engine running, there will be
no power assist for the steering, but you will
still have control of the vehicle. At this time,
greater steering effort is required to operate
the steering wheel, especially in sharp turns
and at low speeds.
For additional information, refer to “Power
steering warning light” in the “Instruments
and controls” section of this manual.

TYPE
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.
5-178Starting and driving

Under the following conditions, the steering
wheel may turn slightly even when driving on
a straight road. This is due to a protection
mechanism for Direct Adaptive Steering. The
steering wheel will return to the normal posi-
tion after the protection mechanism is deac-
tivated.
Condition A:∙ When the engine is stalled or likely to be stalled
∙ When the steering wheel is held in the full lock position or when the front tire
touches an obstruction
∙ When the battery is discharged
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.
Condition B: ∙ When the steering wheel is operated re- peatedly or continuously while parking or
driving at a very low speed. In this case,
the power assist for the steering wheel
will be reduced.
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without oper- ating the steering wheel, until the tempera-
ture of Direct Adaptive Steering cools down.
Avoid repeated steering wheel operations
that could cause Direct Adaptive Steering to
overheat.
When the vehicle is tested on the 2–wheel
dynamometer, the power steering warning
light may illuminate. To turn off the power
steering warning light, stop the vehicle in a
safe location, turn the engine off, restart the
engine, and then drive the vehicle for a period
of time.
The following conditions do not indicate a
malfunction of Direct Adaptive Steering:
∙ You may notice wider steering play when the ignition switch is in the OFF or AUTO
ACC position compared to when it is in
the ON position.
∙ After the engine is started, the steering wheel may turn slightly even when driving
a straight road. To return to the normal
position, drive the vehicle on a straight
road for a period of time.
∙ After the engine is started, the steering wheel may move if the steering wheel
was turned to the fully locked position
while the ignition switch was in the OFF
position. ∙ After the vehicle is tested on the 4–wheel
dynamometer, the steering wheel may
turn slightly even when driving on a
straight road. To return the steering
wheel to the normal position, drive the
vehicle on a straight road for a period of
time.
You may hear a noise under the following
conditions. However, this is not a malfunc-
tion. ∙ When the engine is started or stopped.
∙ When the steering wheel is turned in the full lock position.
