SUPPLEMENTAL RESTRAINT SYSTEM (SRS) (If electrical maintenance is required)
The CR-V SRS includes a driver's airbag inthe steering wheel hub, a passenger's airbag inthe dashboard above the
glove box, seat belt tensioners inthe front seat belt retractors, seat belt buckle tensioners inthe front seat belt buckles,
side curtain airbags inthe sides of the roof, and side airbags inthe front seat-backs. Information necessary to safely
service the SRS is included inthis Service Manual. Items marked with an asterisk ( * 1 on the contents page include or
are located near SRS components. Servicing, disassembling, or replacing these items require special precautions and
tools, and should be done only by an authorized Honda dealer.
To avoid rendering the SRS inoperative, which could lead to personal injury or death inthe event of a severe frontal
or side collision, all SRS service work should be done by an authorized Honda dealer.
Improper service procedures, including incorrect removal and installation of the SRS, could lead to personal injury
caused by unintentional deployment of the airbags and/or side airbags.
Do not bump or impact the SRS unit, front impact sensors, or side impact sensors when the ignition switch is ON (111,
or for at least 3 minutes after the ignition switch is turned OFF; otherwise, the system may fail ina collision, or the
airbags may deploy.
SRS electrical connectors are identified by yellow color coding. Related components are located inthe steering
column, front console, dashboard, dashboard lower panel, inthe dashboard above the glove box, inthe front seats,
inthe roof side, and around the floor. Do not use electrical test equipment on these circuits.
