• Engine coolant
• Washer fluid
● Have a service technician inspec t the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire

When trouble arises
C-HR_OM_USA_OM10634U■
When the tire pressure warning light comes on
Inspect the appearance of the ti
re to check that the tire is not punctured.
If the tire is punctured: P. 436
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered
sufficiently.
●Check the tire inflation pressure and adjust to the appropriate level.
●If the warning light does not go out even after several minutes , check
that the tire inflation pressure is at the specified level and carry out ini-
tialization. ( P. 3 6 4 )
The warning light may come on again if the above operations are con-
ducted without first allowing t he tire temperature to lower suf ficiently.
■The tire pressure warning light may come on due to natural caus es
The tire pressure warning light may come on due to natural caus es such
as natural air leaks and tire inflation pressure changes caused by tem-
perature. In this case, adjusting the tire inflation pressure w ill turn off the
warning light (afte r a few minutes).
■When a tire is replace d with a spare tire
The compact spare tire is not equipped with a tire pressure war ning valve
and transmitter. If a tire goes flat, the tire pressure warning light will not
turn off even though the flat tire has been replaced with the s pare tire.
Replace the spare tire with the repaired tire and adjust the ti re inflation
pressure. The tire pressure war ning light will go off after a few minutes.
■Conditions that the tire pressure warning system may not functi on
properly
 P. 3 6 7
■If the tire pressure warning light frequently comes on after bl inking
for 1 minute
If the tire pressure warning light frequently comes on after bl inking for
1 minute when the engine switch is turned to the “ON” position (vehicles
without smart key system) or IGNITION ON mode (vehicles with sm art
key system), have it checked by your Toyota dealer.
■Warning buzzer

audio sound.

4547-2. Steps to take in an emergency
C-HR_OM_USA_OM10634U
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 m ode, then start the vehicle’s
engine.
Once the vehicle’s engine has st arted, 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 vehicle inspected at your Toyota
dealer as soon as possible.
■ Starting the engine when t he 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 t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ Precautions when the battery is discharged (vehicles with a sma rt key
system)
● In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the battery is discharged. Use the wi reless
remote control or the mechanical key to lock or unlock the door s.
● The engine may not start on the first attempt after the battery has recharged
but will start normally after the second attempt. This is not a malfunction.
● The engine switch mode is memorized by the vehicle. When the ba ttery is
reconnected, the system will return to the mode it was in befor e the battery
was discharged. Before disconnecting the battery, turn the engine switch off.
If you are unsure what mode the engine switch was in before the battery dis-
charged, be especially careful when reconnecting the battery.

When replacing the battery
●Use a battery that conforms to European regulations.
● Use a battery that the case size is same as the previous one, 20 hour rate

equivalent or greater.
Check the label on top of the battery for the battery size and specifications
(ex. LN2, 60Ah, 345A).
• If the sizes differ, the battery cannot be properly secured.
• If the 20 hour rate capacity is low, even if the time period w here the vehi-
cle is not used is a short time, the battery may discharge and the engine
may not be able to start.
