brake NISSAN LEAF 2011 Service Manual

.Do not hang items on the selector
lever. This may cause an accident
due to a sudden start.
. Do not shift to the ECO position
abruptly on slippery roads. This may
cause a loss of control.
NOTE:
If the accelerator pedal is depressed when
the vehicle is in the D (Drive) or ECO
position and the driver’s seat belt is
securely fastened, the parking brake will
be released automatically. See “Electric
parking brake” later in this section.

NOTE:
.While the electric parking brake is
applied or released, an operating
sound is heard from the lower side of
the rear seat. However, this is not a
malfunction.
. When the electric parking brake is
frequently applied and released in a
short period of time, the electric park-
ing brake may not operate in order to
prevent the electric parking brake sys-
tem from overheating. If this occurs,
operate the electric parking brake
again after approximately 1 minute.
. The electric parking brake can be
released with the power switch in the
ON or READY to drive position.
. If the electric parking brake must be
applied while driving in an emergency,
pull up and hold the electric parking
brake switch. When you release the
parking brake switch, the parking
brake will be released.
. While pulling up on the electric parking
brake switch, the electric parking brake
is applied and a chime sounds. The
electric parking brake indicator light in
the meter and parking brake switch operation indicator illuminate. This
does not indicate a malfunction. The
electric parking brake indicator light
and parking switch operation indicator
turn off when the electric parking brake
switch is released.
. Pull up on the electric parking brake
switch twice so that the maximum
electric parking brake force can be
applied to the vehicle.
. When operating the electric parking
brake switch with the power switch in
the ON position, the electric parking
brake indicator light in the meter and
the electric parking brake switch op-
eration indicator turn on.
. Do not start driving while the parking
brake is applied. Doing so may cause
the parking brake to overheat or re-
duce its effectiveness, which could
result in an accident.
. When pulling the electric parking brake
switch with the power switch in the
OFF or ACC position, the electric park-
ing brake switch operation indicator
will continue to illuminate for a short
period of time.

speed driving you may feel that regenerative
brake provides less deceleration than the engine
braking in an ordinary vehicle. This is normal.
Less deceleration is provided by the regenera-
tive brake system when the Li-ion battery is fully
charged. Regenerative brake is automatically
reduced when the Li-ion battery is fully charged
to prevent the Li-ion battery from becoming
overcharged. Regenerative brake is also auto-
matically reduced when the battery temperature
is high/low (indicated by the red/blue zones on
the battery temperature gauge) to prevent Li-ion
battery damage.
The brake pedal should be used to slow or stop
the vehicle depending on traffic or road condi-
tions. The vehicle brakes are not affected by
regenerative brake system operation.
NOTE:
.When applying the regenerative
brakes, you may hear a sound coming
from the regenerative brake system.
This is a normal operating character-
istic of an EV (Electric vehicle) .
. If the power switch position is in a
position other than ON or READY to
drive, 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 the stopping distance will
be longer.
. When depressing the brake pedal, the
braking pedal feel will not be smooth
or may change when the cooperative
regenerative brake system activates.
However, the electronically controlled
brake system is operating normally and
this does not indicate a malfunction.
Using brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake pads and shoes
faster and will reduce driving range.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
select ECO position before going down a slope
or long grade. Overheated brakes may reduce
braking performance and could result in loss of
vehicle control.

ELECTRIC PARKING BRAKE
BREAK-IN
Break in the parking brake shoes whenever the
holding effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums are replaced, in order to maintain
optimum braking performance.
This procedure is described in the vehicle
Service Manual, and it can be performed by a
NISSAN certified LEAF dealer.
ANTI-LOCK BRAKING SYSTEM
(ABS)

the power switch is placed in the OFF position
then back to the ON position.
The computer has a built-in diagnostic feature
that tests the system each time you start the EV
(Electric Vehicle) and move the vehicle forward
or in reverse at a slow speed. 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 indication of a malfunction.

in the P (Park) position, and the electric
parking brake cannot be applied. If this
occurs, place suitable blocks at both
the front and back of a wheel to prevent
the vehicle from moving. Failure to
block a wheel may allow the vehicle to
move unexpectedly which may result in
serious personal injury or death.
To place the vehicle in the READY position so
the vehicle can be driven, charge the Li-ion
battery until the driving range on the instrument
panel changes from “---” to a numeric distance.

.Never tow a vehicle using the vehi-
cle tie down hook or recovery hook.
. Always pull the cable straight out
from the front of the vehicle. Never
pull on the vehicle at an angle.
. Pulling devices should be routed so
they do not touch any part of the
suspension, steering, brake or cool-
ing systems.
. Pulling devices such as ropes or
canvas straps are not recommended
for use in vehicle towing or recov-
ery.
Rocking a stuck vehicle
If the vehicle is stuck in sand, snow, mud, etc.,
try to free it by following the procedure below.
1. Turn off the Vehicle Dynamic Control (VDC)
system.
2. Make sure the area in front and behind the vehicle is clear of obstructions.
3. Turn the steering wheel left and right to clear an area around the front tires.
4. Slowly rock the vehicle forward and back- ward.
.Shift back and forth between the R
(Reverse) and D (Drive) positions.
.Apply the accelerator as little as possible
to maintain the rocking motion.
.Release the accelerator pedal before
shifting between R and D.
.Do not spin the tires above 35 MPH (55
km/h).
5. If the vehicle cannot be freed after a few tries, contact a professional towing service
to remove the vehicle.

If the electric parking brake cannot be released
by operating the electric parking brake switch,
the parking brake can be mechanically released.
Note that the following procedure must be
performed only when the parking brake needs
to be released in an emergency.
NOTE:
.Depending on the type of parking
brake system malfunction, the parking
brake switch operation indicator may
blink and the electric shift control
system warning light may illuminate in
the meter.
. If the electric shift control system
warning light illuminates in the meter,
stop the vehicle in a safe location and
contact a NISSAN certified LEAF dealer
immediately.
. The mechanical release of the parking
brake should only be done if there is a
malfunction of the electric parking
brake system. After the parking brake
mechanical release has been done, the
vehicle needs to be repaired. Have your
vehicle inspected by a NISSAN certified
LEAF dealer.
To release the parking brake mechanically,
perform the following procedure. 1. Confirm that the vehicle is in the P (Park)
position. If the vehicle cannot be placed in
the P (Park) position, contact a NISSAN
certified LEAF dealer.
2. Check that the parking brake switch opera- tion indicator does not illuminate.
3. Place power switch in the OFF position.
4. Open the rear hatch.
5. Remove the tool for mechanical release from the tool set that is located in the cargo area.
6. Remove the luggage floor board from the cargo area.
7. Remove the cap by turning counterclock- wise.
8. Insert the tool and turn it counterclockwise while pushing it in.
9. Continue to turn it until it stops and then release your hand. The tool will then return
approximately the same position it was in
before it was turned and release of the
parking brake will be completed. Do not turn
the tool beyond the point at which it stops.
Doing so may result in damage.
10. Store the tool for mechanical release by performing the procedure for removing it in
reverse.

.If the vehicle is driven with the
electric parking brake applied, the
electric brake components may
overheat causing a deterioration in
electric parking brake effectiveness
and premature electric parking
brake wear.
. The electric parking brake mechan-
ical release tool should be used
only to release the electric parking
brake in an emergency.
NOTE:
The electric parking brake mechanical
release tool can only be used to release
the electric parking brake. It can not to be
used to apply the electric parking brake.
The electric parking brake operation
switch indicator may turn off 1 minute
after the power switch is placed in the OFF
position. If the parking brake switch op-
eration indicator does not turn off, contact
a NISSAN certified LEAF dealer.
