When trouble arises
C-HR_OM_USA_OM10526U
Vehicles without a smart key system:
Maintain the engine speed of the second vehicle and turn the
engine switch to the “ON” position, then start the vehicle’s engine.
Vehicles with a smart key system:
Maintain the engine speed of the second vehicle and turn the
engine switch to IGNITION ON mode, then start the vehicle’s
engine.
Once the vehicle’s engine has started, remove the jumper cables in
the exact reverse order from which they were connected.
To install the engine cover, conduct the removal procedure in
reverse. After installing, check that the fixed pins are inserted
securely.
Once the engine starts, have the v ehicle inspected at your Toyota
dealer as soon as possible.
■ Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ To prevent battery discharge
●Turn off the headlights and the air conditioning system while the engine is
stopped.
● Turn off any unnecessary electrical components when the vehicle is running
at a low speed for an extended period, such as in heavy traffic.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ When exchanging the battery
●Use a battery that conforms to European regulations.
● Use a battery that the case size is same as the previous one (LN2), 20 hour
rate capacity (20HR) is equivalent ( 60Ah) or greater, and performance rating
(CCA) is equivalent (520A) or greater.
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period where the vehi- cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
● For details, consult your Toyota dealer.
