2011 NISSAN ALTIMA HYBRID brake pads

CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Ready operation indicator light(green)
The ready indicator light illuminates when the
Hybrid System is powered and the vehicle may
be driven.
Security indicator light
This light blinks when the ignition switch is
placed in the OFF, LOCK or ACC position.
The blinking security indicator light indicates that
the security systems equipped on the vehicle are
operational.
For additional information, see “Security sys-
tems” later in this section.
Slip indicator light
This indicator light will blink when the traction
control system, Vehicle Dynamic Control System or Anti-lock Braking System is limiting wheel
spin. Slippery road conditions may exist if the slip
indicator blinks on. If this happens, adjust your
driving accordingly.
The slip indicator light also comes on when the
ignition switch is placed in the ON position and
the Hybrid System is in the READY mode. The
light will turn off after about 2 seconds if the
system is operational. If the light does not come
on or does not go off, have the system checked
by a NISSAN dealer.
Turn signal/hazard indicator
lights
The appropriate light flashes when the turn signal
switch is activated.
Both lights flash when the hazard switch is turned
on.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warnings.
When a disc brake pad requires replacement, it
makes a high pitched scraping sound when the
vehicle is in motion, whether or not the brake
pedal is depressed. Have the brakes checked as
soon as possible if the warning sound is heard.
Key reminder chime
A chime sounds if the driver’s door is opened
while the ignition switch is placed in the ACC or
OFF position or placed in the OFF or LOCK
position with the Intelligent Key left in the Intelli-
gent Key port. Make sure the ignition switch is
placed in the LOCK position, and take the Intel-
ligent Key with you when leaving the vehicle.
Light reminder chime
With the ignition switch placed in the OFF posi-
tion, a chime sounds when the driver’s door is
opened if the headlights or parking lights are on.
Turn the headlight control switch off before leav-
ing the vehicle.
NISSAN Intelligent Key™ door buzzer
The Intelligent Key door buzzer sounds if the
Intelligent Key is left inside the vehicle when
locking the doors. When the buzzer sounds, be
sure to check both the vehicle and the Intelligent
Key. See “NISSAN Intelligent Key™” in the “Pre-
driving checks and adjustments” section.
Instruments and controls2-17

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.● When you open a door.
● When the brake pedal is depressed firmly. ●
When the brake pedal is depressed repeat-
edly.
● When the Hybrid System is in the READY
mode.
● When 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.
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.
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.
5-20Starting and driving

Normal operation
The ABS operates at speeds above4-6MPH(7
- 10 km/h) . The speed varies according to road
conditions.
When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. 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 theSLIPindica-
tor light blinks, the road conditions are hazardous
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.
● When the TCS is operating, the slip indica-
tor in the instrument panel blinks.
● If the slip indicator blinks, the vehicle is may
be under slippery conditions. Be sure to
drive carefully.
● If 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
● The 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. ●
If 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.
● Do 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.
● If 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.
● The Traction Control System is not a
substitute for winter tires or tire chains
on a snow covered road.
TRACTION CONTROL SYSTEM (TCS)
5-22Starting and driving

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving situations, the
system will control braking and engine output to
help keep the vehicle on its steered path.● When the Vehicle Dynamic Control (VDC)
system is operating, the SLIPindicator in
the instrument panel blinks.
● If the SLIP indicator 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.
● Indicator 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, you
may hear a clunk noise. This is not an indication of
a malfunction and indicates that the VDC system
is working properly.
WARNING
●
The 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.
● Do 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.
● If 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. ●
When 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.
● When 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.
● If 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.
● The Vehicle Dynamic Control system is
not a substitute for winter tires or tire
chains on a snow covered road.

6. Return the wiper to its original position andrelease it until it has made contact with the
windshield.
CAUTION
●After wiper blade replacement, return
the wiper arm to its original position;
otherwise it may be damaged when the
hood is opened.
● Make sure the wiper blades contact the
glass; otherwise the arms may be dam-
aged from wind pressure.
If you wax the surface of the hood, be careful not
to let wax get into the windshield washer nozzle
A. This may cause clogging or improper wind-
shield washer operation. If wax gets into the
nozzle, remove it with a needle or small pin
B. If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
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
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR INDICATORS
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing 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, occa-
sional 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.
