brake rotor NISSAN ALTIMA 2007 L32A / 4.G Owners Manual

The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
harder to operate.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brakes and 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.
WARNING
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
cIf the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
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.

Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) .
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies and releases hydraulic pressure.
This action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is oper-
ating. This is normal and indicates that the ABS is
operating properly. However, the pulsation may
indicate that 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 stability while accelerating.
cWhen the traction control system is operat-
ing, the slip indicator in the instrument panel
blinks.
cIf the slip indicator blinks, the vehicle is un-
der slippery conditions. Be sure to drive
carefully. See “Slip indicator light” and “Trac-
tion control system (TCS) off indicator light”
in the “Instruments and controls” section of
this manual.
cIf a malfunction occurs in the system,
the
andindicator lights
come on in the instrument panel.
As long as these lights are on, the traction control
function is canceled. The vehicle will behave like
a vehicle without the system.
WARNING
cThe traction control system is designed
to help improve driving 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 sur-
faces 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
indicator light may come on.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs and bushings
are not standard equipment or are ex-
tremely deteriorated, the traction con-
trol system may not operate properly
and the
indicator 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 vehicle dynamic control off indica-
tor light may come on.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars
and bushings are not NISSAN approved
for your vehicle or are extremely dete-
riorated the vehicle dynamic control
system may not operate properly. This
could adversely affect vehicle handling
performance, and the VDC OFF indica-
tor 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 OFF
indicator 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 vehicle dynamic control off
indicator light may illuminate. 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 vehicle dynamic con-
trol off indicator light may come on.
cThe vehicle dynamic control system is
not a substitute for winter tires or tire
chains on a snow covered road.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
