1997 NISSAN ALTIMA mileage

while driving. This overheats the brakes,
increases wear on the brake linings and
pads, and reduces 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 accel-
erating could cause the wheels to skid
and result in an accident.The anti-lock brake system installed in
some models controls the brakes at each
wheel so the wheels do not lock when
braking abruptly or when braking on slip-
pery surfaces. The system detects the rota-
tion speed at each wheel and varies the
brake fluid pressure to prevent each wheel
from locking and sliding. By preventing
wheel lockup, the system helps the driver
maintain steering control and helps to mini-
mize swerving and spinning on slippery
surfaces.
Using the System
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Normal operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h) to completely stop the vehicle. (The
speeds vary according to road conditions.)
When the anti-lock system senses that one
or more wheels are close to locking up, theactuator (under the hood) rapidly applies
and releases hydraulic pressure (like pump-
ing the brakes very quickly). While the ac-
tuator is working, you may feel a pulsation in
the brake pedal and hear a noise or vibra-
tion from the actuator under the hood. This
is normal and indicates that the anti-lock
system is working properly. However, the
pulsation may indicate that road conditions
are hazardous and extra care is required
while driving.
Self-test feature
The anti-lock brake system is sophisticated,
with electronic sensors, electric pumps, and
hydraulic solenoids controlled by a com-
puter. The computer has a built-in diagnos-
tic feature that tests the system each time
you start the engine and move the vehicle at
a low speed in forward or reverse. 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 indica-
tion of any malfunction. If the computer
senses any malfunction, it switches the anti-
lock brake system OFF and turns on the
ABS brake warning light in the dashboard.
The brake system then operates normally,
but without anti-lock assistance.

To ensure smooth, trouble-free, safe and
economical driving, NISSAN provides two
different maintenance schedules that may
be used, depending upon the conditions in
which you usually drive. These schedules
contain both distance and time intervals, up
to 60,000 miles (96,000 km)/48 months. For
most people, the odometer reading indi-
cates when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals shown
in the schedule.After 60,000 miles (96,000
km) or 48 months, continue periodic
maintenance at the same mileage/time
intervals.
SCHEDULE 1
Follow Periodic Maintenance Schedule 1 if
your driving habits frequently include one or
more of the following driving conditions:
cRepeated short trips of less than 5
miles (8 km).
cRepeated short trips of less than 10
miles (16 km) with outside tempera-
tures remaining below freezing.
cOperating in hot weather during stop-
and-go ``rush hour'' traffic.cExtensive idling and/or low speed
driving for long distances, such as
police, taxi or door-to-door delivery
use.
cDriving in dusty conditions.
cDriving on rough, muddy, or salt
spread roads.
cTowing a trailer, using a camper or a
car-top carrier.
SCHEDULE 2
Follow Periodic Maintenance Schedule 2 if
none of the driving conditions shown in
Schedule 1 apply to your driving habits.
