• While the electronic parking brake is ap-plied or released, an operating sound is
heard from the lower side of the rear seat.
This is normal and does not indicate a
malfunction.
• When the electronic parking brake is fre- quently applied and released in a short pe-
riod of time, the parking brake may not
operate in order to prevent the parking
brake system from overheating. If this oc-
curs, operate the electronic parking brake
switch again after waiting approximately
1 minute.
• If the electronic parking brake must be ap- plied while driving in an emergency, pull up
and hold the parking brake switch. When
you release the parking brake switch, the
parking brake will be released.
• While pulling up the electronic parking brake switch during driving, the parking
brake is applied and a chime sounds. The
electronic parking brake indicator light
(red) in the meter and in the parking brake
switch illuminates. This does not indicate a
malfunction. The electronic parking brake
indicator light (red) in the meter and in the
parking brake switch turns off when the
parking brake is released. • 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 soonas 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 auto-
matic brake hold when the vehicle is
stopped on a steep hill or slippery road.
Failure to do so may cause the vehicle to
move.
• The automatic brake hold function is de-
signed to operate on gradients between
—30% to +30%. Outside this range the
system may not operate. The automatic
brake hold warning may appear in the
Vehicle Information Display to request
that the driver retake control by de-
pressing the brake pedal.

wash or towing your vehicle.
• Make sure to place the shift lever in the P
(Park) position and apply the parking
brake when parking your vehicle, riding
on or off the vehicle, or loading luggage.
Failure to do so could cause the vehicle to
move or roll away unexpectedly and re-
sult in serious personal injury or property
damage.WARNING

the automatic brake hold function may
not function. Have the system checked
promptly. It is recommended that you
visit an INFINITI retailer for this service.
Failure to operate the vehicle in accor-
dance with these conditions could cause
the vehicle to move or roll away unex-
pectedly and result in serious personal
injury or property damage.
– A warning message appears in the ve-
hicle information display.
– The indicator light on the automatic
brake hold switch does not illuminate
when the switch is pushed.
• The automatic brake hold function will
not be activated if the Slip indicator
light, electronic parking brake warning
light or master warning light illuminate
and the chassis control system fault
message appears in the vehicle informa-
tion display.
• To maintain the braking force to keep
the vehicle to a standstill, a noise may be
heard. This is not a malfunction.
