parking brake NISSAN LEAF 2012 Service Manual

CAUTION
.Be sure to carry the Intelligent Key
with you when operating the vehi-
cle.
. Never leave the Intelligent Key in
the vehicle when you leave the
vehicle.
The Intelligent Key is always communicating with
the vehicle because it receives radio waves. The
Intelligent Key system transmits weak radio
waves. Environmental conditions may interfere
with the operation of the Intelligent Key system
under the following operating conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station or broad-
casting station.
. When in possession of wireless equipment,
such as a cellular phone, transceiver or CB
radio.
. When the Intelligent Key is in contact with or
covered by metallic materials.
. When any type of radio wave remote control
is used nearby. .
When the Intelligent Key is placed near an
electric appliance such as a personal
computer.
. When the vehicle is parked near a parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depending
on the operating conditions, the battery’s life is
approximately 2 years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is almost
discharged, firmly apply the foot brake and
touch the power switch with the Intelligent Key.
Then push the power switch while depressing
the brake pedal within 10 seconds after the
chime sound.
Since the Intelligent Key is continuously receiv-
ing radio waves, if the key is left near equipment
that transmits strong radio waves, such as
signals from a TV or personal computer, the
battery life may become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replacement”
in the “8. Maintenance and do-it-yourself”
section. Pay special attention that the vehicle battery is
not completely discharged.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information about
the purchase and use of additional Intelligent
Keys, contact a NISSAN certified LEAF dealer.

.Do not place metalized film or any
metal parts (antenna, etc.) on the
windows. This may cause poor re-
ception of the signals from the tire
pressure sensors, and the TPMS will
not function properly.
Some devices and transmitters may temporarily
interfere with the operation of the TPMS and
cause the low tire pressure warning light to
illuminate. Some examples are:
. Facilities or electric devices using similar
radio frequencies that are near the vehicle.
. If a transmitter set to similar frequencies is
being used in or near the vehicle.
. If a computer (or similar equipment) or a DC/
AC converter is being used in or near the
vehicle.

TPMS with Easy Fill Tire Alert
When tire pressure is low, the low tire pressure
warning light illuminates.
This vehicle provides visual and audible signals
to help you inflate the tires to the recommended
COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level place.
2. Apply the parking brake and push the P
position switch on the selector lever.
3. Place the power switch in the ON position. Do not place in the READY to drive mode. Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indicators
will start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard
indicators stop flashing.
4. Perform the above steps for each tire.
. If the tire is over-inflated more than approxi-
mately 4 psi (30 kPa), the horn beeps and
the hazard indicators flash 3 times. To
correct the pressure, push the core of the
valve stem on the tire briefly to release
pressure. When the pressure reaches the
designated pressure, the horn beeps once.
. If the hazard indicator does not flash within
approximately 15 seconds after starting to
inflate the tire, it indicates that the Easy Fill
Tire Alert is not operating.
. The TPMS will not activate the Easy Fill Tire
Alert under the following conditions:
— If there is interference from an external
device or transmitter.
— The air pressure from the inflation device is not sufficient to inflate the tire such as
those using a power socket.

.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.

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.

Do not allow the two vehicles to touch.
2. Apply the parking brake.
If the 12-volt battery is discharged, the
power switch cannot be moved from
the OFF position. Connect the jumper
cables to the booster vehicle
*Bbefore
pushing the power switch.
3. Push the P position switch to place the vehicle in the P (Park) position.
4. Switch off all unnecessary electrical systems (headlights, heater, air conditioner, etc.).
5. Place the power switch in the OFF position.
6. Remove the vent caps on the 12-volt battery (if so equipped) . Cover the battery with a
firmly wrung out moist cloth to reduce the
hazard of an explosion.
7. Connect jumper cables in the sequence as illustrated (
*1?*2?*3?*4).

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.
