brake rotor NISSAN ALTIMA HYBRID 2009 L32A / 4.G Owners Manual

Hydraulic system
The brake system has separate hydraulic circuits.
If one circuit malfunctions, you will still have brak-
ing at other wheels.
However, the brake pedal will have to be de-
pressed harder and your stopping distance will
increase. The brake system warning light will also
come on.
Brake actuator
The brake actuator uses a pump to provide
power assisted braking.
The brake warning light comes on if the actuator
is not functioning properly. The brake pedal will
be hard to depress and stopping distance will
increase. Depress the brake pedal firmly to stop
the vehicle in a safe place and contact a NISSAN
dealer.
If the brake pedal is depressed repeatedly, the
brake warning light may turn on. However this is
normal if the light turns off after a few seconds.
Noise may be heard in the engine room under the
following conditions. This is a normal operating
characteristic and does not indicate a malfunc-
tion.
cWhen you open a door.
cWhen the brake pedal is depressed firmly.cWhen the brake pedal is depressed repeat-
edly.
cWhen the Hybrid System is in the READY
mode.
cWhen the Hybrid System is turned off.
It may be hard to depress the brake pedal or the
pedal stroke may be short with the Hybrid System
OFF. This is not a malfunction.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear 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.
When applying the brakes, you may hear a sound
coming from the braking system. This is normal.
WARNING
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or acceler-
ating could cause the wheels to skid and
result in an accident.
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
drum/rotors are replaced, in order to assure the
best brake performance.
This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
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 the brakes, drive the vehicle at a safe
speed while lightly pressing 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.

When the ABS senses that one or more wheels
are close to locking up, the system electronically
controls the pressure applied to each brake.
This action is similar to pumping the brakes very
quickly. You may hear a noise from under the
hood or feel a vibration from the actuator when it
is operating. This is normal and indicates that the
ABS is operating properly. However, if the SLIP
indicator light blinks, the road conditions are haz-
ardous and extra care is required while driving.When accelerating on slippery surfaces the tire
may spin or slip. With the vehicle Traction Control
System (TCS) , sensors detect these movements
and control the braking and engine output to help
improve vehicle road traction.
cWhen the TCS is operating, the slip indica-
tor in the instrument panel blinks.
cIf the slip indicator blinks, the vehicle is may
be under slippery conditions. Be sure to
drive carefully.
cIf a malfunction occurs in the system, the
VDC warning light illuminates in the instru-
ment panel.
As long as the VDC warning light is on, the
traction control function is canceled. The vehicle
will behave like a vehicle without the system.
WARNING
cThe Traction Control System is de-
signed to help maintain traction with
the road surface but does not prevent
accidents due to abrupt steering opera-
tion 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.cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the Traction Control System
may not operate properly and the VDC
warning light may come on.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, bushings and
wheels are not standard equipment or
are extremely deteriorated, the Traction
Control System may not operate prop-
erly and the VDC warning light may
come on.
cIf wheels or tires other than the recom-
mended ones are used, the Traction
Control System may not operate prop-
erly and the VDC warning light may
come on.
cThe Traction Control System is not a
substitute for winter tires or tire chains
on a snow covered road.

The Vehicle Dynamic Control (VDC) system uses
sensors within the vehicle to detect these move-
ments. The VDC system helps control brake and
engine output to help minimize tire slip and spin.
cWhen the Vehicle Dynamic Control (VDC)
system is operating, theSLIPindicator in
the instrument panel blinks.
cIf theSLIPindicator blinks, the road condi-
tions may be slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle Dynamic
Control warning light” in the “Instruments
and controls” section.
cIndicator light
If a malfunction occurs in the system, the
VDC warning light comes on in the instru-
ment panel.
As long as this warning light is on, the trac-
tion control and the Vehicle Dynamic Control
functions are canceled.
When the VDC system is operating, you may
hear a noise or vibration from under the hood.
This is normal and indicates that the VDC system
is working properly.
The computer has a built in diagnostic feature
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, youmay hear a clunk noise. This is not an indication of
a malfunction and indicates that the VDC system
is working properly..
WARNING
cThe Vehicle Dynamic Control system is
designed to help improve driving stabil-
ity 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 sur-
faces and always drive carefully.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, bushings and
wheels are not standard equipment or
are extremely deteriorated, the Traction
Control System may not operate prop-
erly and the VDC warning light may
come on.
cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the Vehicle Dynamic Control
system may not operate properly and
the VDC warning light may come on.cWhen driving on extremely inclined sur-
faces such as higher banked corners,
the Vehicle Dynamic Control system
may not operate properly and the VDC
warning light may come on. Do not drive
on these types of roads.
cWhen driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the VDC warning light may illumi-
nate. This is not a malfunction. Restart
the engine after driving onto a stable
surface.
cIf wheels or tires other than the recom-
mended ones are used, the Vehicle Dy-
namic Control system may not operate
properly and the VDC warning light may
come on.
cThe Vehicle Dynamic Control system is
not a substitute for winter tires or tire
chains on a snow covered road.
