WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING
•Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to
personal injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and
paassenger (from rendering the SRS inoperative).
•Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.
•MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: SRS air bag control unit, SRS warning light, front impact sensors, air bag module,
clock spring, and interconnecting wiring. Other SRS-related components (that may have to be removed/installed in connection

FLUID LEVEL AND SPECIFIC GRAVITY
CHECK
M1541001000438
CAUTION
•If the battery fluid is below the LOWER
LEVEL, the battery could explode in using.
•If the battery fluid is over the UPPER LEVEL,
leakage could result.
1. Inspect whether or not the battery fluid is between
the UPPER LEVEL and LOWER LEVEL marks.
2. Use a hydrometer and thermometer to check the
specific gravity of the battery fluid.
Standard value: 1.220 − 1.290 (20°C)
3. The specific gravity of the battery fluid varies with
the temperature, so use the following formula to
calculate the specific gravity for 20°C. Use the
calculated value to determine whether or not the
specific gravity is satisfactory.
D20 = (t − 20) X 0.0007 + Dt
D20: Specific gravity of the battery fluid
calculated for 20°CDt: Actually measured specific gravity
t: Actually measured temperature
CHARGINGM1541001100509
CAUTION
•The battery plus should be removed during
charging.
•The battery electrolyte level may rise and
overflow from the battery during charging.
•Explosions may occur if the battery is
brought close to naked flames during
charging.
•Be careful to avoid tasks that might produce
sparks or other danger while the battery is
charging.
•After charging is complete, replace the
battery plus, pour water over the battery to
rinse away any sulphuric acid, and let the
battery stand to dry.
•Charge the battery in a well-ventilated
location.
•Do not let the battery electrolyte temperature
rise above approximately 45°C (approximately
55°C during rapid 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.
3. Determine when charging is finished.
•When the specific gravity of the battery
electrolyte is constantly within 1.250 − 1.290 for a
continuous period of one hour or more.•When the voltage per cell during charging is 2.5 −
2.8 V constantly for a continuous period of one
hour or more. Items Specification
