■After a fuse is replaced
● If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. ( P. 651)
● If the replaced fuse blows again, have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness f rom damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits design ed to prevent
overload, non-genuine parts or parts not designed for this vehi cle may be
unusable.
WARNING
■ To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.
● Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired b y any

C-HR_HEV_OM_Europe_OM10764E
Make sure the “READY” indicator comes on. If the indicator light
does not come on, contact any authorized Toyota retailer or Toy ota

Once the hybrid system has started, remove the jumper cables in
the exact reverse order from which they were connected.
For M20A-FXS engine: Close the exclusive jump starting terminal
cover, and reinstall the fuse box cover to its original positio n.
Once the hybrid system starts, have the vehicle inspected at an y
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer as soon as possible.
■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
● Turn off the headlights and the audio system while the hybrid system is off.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic .
■ When the 12-volt battery is removed or discharged
● Information stored in the ECU is cleared. When the 12-volt battery is
depleted, have the vehicle inspected at any authorized Toyota r etailer or
Toyota authorized repairer, or any reliable repairer.
● Some systems may require initialization. (P. 791)
■ When removing the 12-volt battery terminals
When the 12-volt battery terminals are removed, the information stored in the
ECU is cleared. Before removing the 12-volt battery terminals, contact any
authorized Toyota retailer or Toyota authorized repairer, or an y reliable
repairer.
■ Charging the 12-volt battery
The electricity stored in the 12- volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the dra ining effects of
certain electrical appliances. If the vehicle is left for a lon g time, the 12-volt
battery may discharge, and the hybrid system may be unable to s tart. (The
12-volt battery recharges automat ically while the hybrid system is operating.)
