may damage the emission control sys-
tem.
To reduce or avoid emission control
system damage:
1) Do not drive at speeds above 45MPH (72 km/h).
2) Avoid hard acceleration or decelera- tion.
3) Avoid steep uphill grades.
4) If possible, reduce the amount of cargo being hauled or towed.
The malfunction indicator light may stop
blinking and remain on.
Have the vehicle inspected. It is recom-
mended you visit an INFINITI retailer for
this service. You do not need to have
your vehicle towed to the retailer.
CAUTION
Continued vehicle operation without
having the emission control system
checked and repaired as necessary could
lead to poor driveability, reduced fuel
economy, and possible damage to the
emission control system.
READY to drive indicator light
The READY to drive indicator light illumi-
nates when the hybrid system is powered
and the vehicle may be driven.
Security indicator light
The light blinks when the ignition switch is in
the ACC, OFF or LOCK position. This
function indicates the security system
equipped on the vehicle is operational.
If the security system is malfunctioning, this
light will remain on while the ignition switch
is in the ON position. For additional informa-
tion, see “Security systems” (P.2-32).
Turn signal/hazard indicator
lights
The light flashes when the turn signal switch
lever or hazard switch is turned on.
Vehicle Dynamic Control
(VDC) off indicator light
When the ignition switch is in the ON
position, the Vehicle Dynamic Control
(VDC) off indicator light illuminates and then
turns off.
The light comes on when the vehicle dynamic
control off switch is pushed to OFF. This indicates that the vehicle dynamic control
system and traction control system are not
operating.
AUDIBLE REMINDERS

A chime will sound if the driver side door is
opened while the ignition switch is pushed to
the ACC position. Make sure the ignition
switch is pushed to the OFF position, and
take the Intelligent Key with you when
leaving the vehicle.
Light reminder chime
A chime will sound when the driver side door
is opened with the light switch in theorposition and the ignition switch in the
ACC, OFF or LOCK position.
Turn the light switch off when you leave the
vehicle.
Parking brake reminder chime
The parking brake reminder chime will sound
if the vehicle is driven at more than 4 MPH (7
km/h) with the parking brake applied. Stop
the vehicle and release the parking brake.
Brake pad wear warning
The disc brake pads have audible wear
warnings. When a brake pad requires repla-
cement, it will make a high pitched scraping

BRAKING PRECAUTIONS
This vehicle is equipped with two braking
systems.
.Hydraulic brake system
. Regenerative brake system
Hydraulic brake system
The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
Regenerative brake system
Refer to the “Regenerative brake” (P.Hybrid
System-8).
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be longer
and the vehicle may pull to one side during
braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced, in
order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended you visit
an INFINITI retailer for this service.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out the brake and pads
faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance and
could result in loss of vehicle control.
WARNING
.While driving on a slippery surface,
be careful when braking, accelerating
or downshifting. Abrupt braking or
accelerating could cause the wheels
to skid and result in an accident. .
If the INFINITI Direct Response Hy-
brid
®System is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
CAUTION
You may hear a operational noise when
the brake pedal is depressed. This is not
malfunction.
BRAKE SYSTEM

Control (VDC) off indicator light” (P.2-20).
The computer has a built-in diagnostic
feature that tests the system each time you
start the INFINITI Direct Response Hybrid
®
System 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 mal-
function.
ACTIVE TRACE CONTROL (if so
equipped)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and individually controls the brak-
ing to each of the four wheels to help
smooth vehicle response.
When the INFINITI Drive Mode Selector is
set to the “SPORT” mode, the amount of
brake control provided by active trace con-
trol is reduced.
When the VDC OFF switch is used to turn
off the VDC system, the active trace control
system is also turned off.
If the active trace control is not functioning
properly, the Forward Emergency Braking
(FEB) system warning light illuminates in the
instrument panel.
RISE-UP AND BUILD-UP
The system gradually adjusts braking power
during normal braking to help provide an
enhanced brake feel.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.
WARNING
.The VDC system is designed to help
the driver maintain stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
by careless or dangerous driving
techniques. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces
and always drive carefully.
. The active trace control (if so
equipped), rise-up and build-up and
brake force distribution systems may
not be effective depending on the
driving condition. Always drive care-
fully and attentively.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as shock absorbers, struts, springs, sta-
bilizer bars, bushings and wheels are
not INFINITI recommended for your
vehicle or are extremely deteriorated,
the VDC system may not operate
properly. This could adversely affect
vehicle handling performance, and
the VDC warning light
may
illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are not
INFINITI recommended or are extre-
mely deteriorated, the VDC warning
light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the VDC warning
light
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 VDC warning light
may
illuminate. This is not a malfunction.

Be careful not to clog the washer nozzle.
This may cause improper windshield washer
operation. If the nozzle is clogged, remove
any objects with a needle or small pin
.Be
careful not to damage the nozzle. If the brakes do not operate properly, it is
recommended you have the brakes checked
by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjusting
brakes.
The 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
normal. It is recommended you visit an
INFINITI retailer for this service.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires repla-
cement, it will make a high pitched scraping
sound when the vehicle is in motion. This
scraping sound will first occur only when the
brake pedal is depressed. After more wear of
the brake pad, the sound will always be
heard even if the brake pedal is not
depressed. Have the brakes checked as soon
as possible if the wear warning sound is
heard.Under some driving or climate conditions,
occasional 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, see the
maintenance schedule shown in the “9.
Maintenance and schedules” section.
