Warning and Indicator Lights (cont'd)
Charging System Warning Light
The charging system warning light comes on when there is a
problem with the electrical charging system or when the igni-
tion switch is turned on with the engine not running. If the light
comes on while driving, stop the car and check the alternator
belt for proper tension. With the engine stopped, push down
on the middle of the belt as shown; it should have 10 — 1 2 mm
(0.4 - 0.5 in) deflection under a force of 98 N (22 Ib).
If the engine has been running, some engine components
may be hot enough to burn you.
Keep hands away from the radiator fan. The fan may start
automatically without warning and run for up to 15 minutes,
even after the engine is turned off.
NOTE: If necessary, have the charging system checked by an
authorized Honda dealer.
Check Engine Warning Light
This light comes on for a couple of seconds each time the igni-
tion is turned on. It will also come on, and remain on, if there is
a malfunction in the emission control system. If the light
comes on while driving, avoid driving at high speed, and have
the system checked by a Honda dealer as soon as possible.
