brakes NISSAN ALTIMA 2012 Owners Manual

avoid driving when tired. Never drive when under
the influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness) . Always wear your seat belt
as outlined in the “Safety – Seats, seat belts and
supplemental restraint system” section of this
manual, and also instruct your passengers to do
so.
Seat belts help reduce the risk of injury in colli-
sions and rollovers.In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or
killed than a person properly wearing a
seat belt.
OFF-ROAD RECOVERY
If the right side or left side wheels unintentionally
leave the road surface, maintain control of the
vehicle by following the procedure below. Please
note that this procedure is only a general guide.
The vehicle must be driven as appropriate based
on the conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheel with both hands and try to hold a straight
course. 4. When appropriate , slowly release the accel-
erator pedal to gradually slow the vehicle.
5. If there is nothing in the way, steer the ve- hicle to follow the road while vehicle speed
is reduced. Do not attempt to drive the ve-
hicle back onto the road surface until vehicle
speed is reduced.
6. When it is safe to do so, gradually turn the steering wheel until both tires return to the
road surface. When all tires are on the road
surface, steer the vehicle to stay in the ap-
propriate driving lane.
● If you decide that it is not safe to return the
vehicle to the road surface based on vehicle,
road or traffic conditions, gradually slow the
vehicle to a stop in a safe place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can occur
if the tire is punctured or is damaged due to
hitting a curb or pothole. Rapid air pressure loss
can also be caused by driving on under-inflated
tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at highway
speeds.
Help prevent rapid air pressure loss by maintain-
ing the correct air pressure and visually inspect the tires for wear and damage. See “Wheels and
tires” in the “Maintenance and do-it-yourself”
section of this manual. If a tire rapidly loses air
pressure or “blows-out” while driving, maintain
control of the vehicle by following the procedure
below. Please note that this procedure is only a
general guide. The vehicle must be driven as
appropriate based on the conditions of the ve-
hicle, road and traffic.

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.
ANTI-LOCK BRAKING SYSTEM
(ABS)

Normal operation
The ABS operates at speeds above3-6MPH(5
- 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 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 operating. 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 re-
quired while driving.The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving conditions,
the VDC System helps to perform the following
functions:
● Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.
When the VDC system operates, the

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)* When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation* Tires should be rotated every
7,500 miles (12,000 km) .
Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades* Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found later in this sec-
tion.
Accelerator pedal Check the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal. Brake pedal
Check the pedal for smooth opera-
tion. If the brake pedal suddenly goes down fur-
ther than normal, the pedal feels spongy or the
vehicle seems to take longer to stop, see a
NISSAN dealer immediately. Keep the floor mat
away from the pedal.
Brakes Check that the brakes do not pull the
vehicle to one side when applied.
Continuously Variable Transmission (CVT)
P (Park) position mechanism On a fairly
steep hill, check that the vehicle is held securely
with the shift selector in the P (Park) position
without applying any brakes.
Parking brake Check the parking brake opera-
tion regularly. The vehicle should be securely held
on a fairly steep hill with only the parking brake
applied. If the parking brake needs adjustment,
see a NISSAN dealer.
Seats Check seat position controls such as seat
adjusters, seatback recliner, etc., to ensure they
operate smoothly and all latches lock securely in
every position. Check that the head restraints
move up and down smoothly and the lock knobs
(if so equipped) hold securely in all latched posi-
tions.
Seat belts Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
Maintenance and do-it-yourself8-3

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.

To drive away:1. Start the vehicle.
2. Apply and hold the brake pedal.
3. Shift the transmission into gear.
4. Release the parking brake.
5. Drive slowly until the vehicle and trailer are clear from the blocks.
6. Apply and hold the brake pedal.
7. Have someone retrieve and store the blocks. ● While going downhill, the weight of the
trailer pushing on the tow vehicle may dete-
riorate overall handling characteristics.
Therefore, to maintain adequate control, re-
duce your speed and shift to a lower gear.
Avoid long or repeated use of the brakes
when descending a hill, as this reduces their
effectiveness and could cause overheating.
Shifting to a lower gear instead provides
“engine braking” and reduces the need to
brake as frequently.
● If the engine coolant temperature rises to a
high temperature, refer to “If your vehicle
overheats” in the “In case of emergency”
section of this owner’s manual.
● Trailer towing requires more fuel than normal
circumstances. ●
Avoid towing a trailer for your vehicle’s first
500 miles (805 km) .
● For the first 500 miles (805 km) that you do
tow, do not drive over 50 MPH (80 km/h) .
● Have your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
● When making a turn, your trailer wheels will
be closer to the inside of the turn than your
vehicle wheels. To compensate for this,
make a larger than normal turning radius
during the turn.
● Crosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling.
Do the following if the trailer begins to sway: 1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer as
straight ahead as the road conditions allow.
This combination will help stabilize the ve-
hicle
– Do not correct trailer sway by steering or applying the brakes. 2. When the trailer sway stops, gently apply the
brakes and pull to the side of the road in a
safe area.
3. Try to rearrange the trailer load so it is bal- anced as described earlier in this section.
● Be careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
● Use the Tow Mode or downshift the trans-
mission to a lower gear for engine braking
when driving down steep or long hills. This
will help slow the vehicle without applying
the brakes.
● Avoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
● Increase your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
● NISSAN recommends that the cruise con-
trol not be used while towing a trailer.
