PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS), SEAT BELT WITH PRE-TENSIONER
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B - Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the battery cable is disconnected.
(3) Warning labels must be heeded when servicing or handling SRS components and seat belt with
pre-tensioner. Warning labels are located in the following locations.
DHood
DSun visor
DGlove box
DSRS-ECU
DSteering wheel
DSteering gearbox
DAir bag module (driver’s side and front passenger’s side)
DFront impact sensor
DClock spring
DSeat belt with pre-tensioner
DSide air bag module
DSide impact sensor
(4) Always use the designated special tools and test equipment.
(5) Store components removed from the SRS and seat belt with pre-tensioner in a clean and dry
place.
The air bag module and seat belt with pre-tensioner should be stored on a flat surface and
placed so that the pad surface is facing upward.
Do not place anything on top of it.
(6) Never attempt to disassemble or repair the SRS components (SRS-ECU, air bag module, clock
spring and side impact sensor) and seat belt with pre-tensioner.
(7) Whenever you finish servicing the SRS and seat belt with pre-tensioner, check the SRS warning
lamp operation to make sure that the system functions properly.
(8) Be sure to deploy the air bag and seat belt with pre-tensioner before disposing of the air bag
module and seat belt with pre-tensioner or disposing of a vehicle equipped with an air bag and
seat belt with pre-tensioner. (Refer to GROUP 52B - Air Bag Module and Seat Belt with Pre-tensioner
Disposal Procedures.)
2. Observe the following when carrying out operations on places where SRS components and seat
belt with pre-tensioner are installed, including operations not directly related to the SRS air bag and
seat belt with pre-tensioner.
(1) When removing or installing parts do not allow any impact or shock to the SRS components
and seat belt with pre-tensioner.
(2) SRS components and seat belt with pre-tensioner should not be subjected to heat, so remove
the SRS components and seat belt with pre-tensioner before drying or baking the vehicle after
painting.
DSRS-ECU, air bag module, clock spring, front and side impact sensors: 93_C or more
DSeat belt with pre-tensioner: 90_C or more
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

CHASSIS ELECTRICAL-Battery54A-5
CHARGING
1. Remove the battery from the vehicle.
2. The normal charging current is a value in amperes which is 1/10th of the battery capacity. If the
battery needs to be charged rapidly because of reasons such as time limitations, the maximum charging
current for rapid charging is the battery capacity expressed as an ampere value.
Battery typeCapacity (5-hour rate)Normal charging currentRapid charging current
75D2354 A5.4 A54 A
80D2658 A5.8 A58 A
95D3170 A7.0 A70 A
3. Determine when charging is finished.
DWhen the specific gravity of the battery electrolyte is constantly within 1.250 - 1.290 for a continuous
period of one hour or more
DWhen the voltage per cell during charging is 2.5 - 2.8 V constantly for a continuous period of one hour
or more
Caution
1. The battery plugs should be removed during charging.
2. The battery electrolyte level may rise and overflow from the battery during charging.
3. Explosions may occur if the battery is brought close to naked flames during charging.
4. Be careful to avoid tasks that might produce sparks or other danger while the battery is charging.
5. After charging is complete, replace the battery plugs, pour water over the battery to rinse
away any sulphuric acid, and let the battery stand to dry.
6. Charge the battery in a well-ventilated location.
7. Do not let the battery electrolyte temperature rise above approximately 45
°C (approximately
55
°C during rapid charging).
BATTERY TEST
Test procedure
OK
NG
Replace
Re-test
OK
Normal
(1) Connect a battery tester to the battery.
(2) Apply aloadwith the specified current to the battery.(Refer
to Table 1.)
(3) After measuring the battery voltage after 15 seconds,
remove the loadcurrent.
(4) Compare the measurement value with the specified
minimum voltage.(Refer to Table 2.)
OK:Higher than the minimum voltage
Measure the battery discharge voltage.
OK:12.4 V or more (specific gravity 1.240)NGCharge the battery at 5 A (constant current charging). (Refer
to Table 1.)
(1) Turn on the headlamps for 15 seconds.
(2) Turn off the headlamps and let the battery stand for 2
minutes to allow the battery voltage to stabilise.
(3) Disconnect the battery cables.
