For safety and security
C-HR_HEV_OM_Europe_OM10764E
■Regenerative braking
● In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the rech arging of the
hybrid battery (traction battery).
• The accelerator pedal is released while driving with the shift lever in D, B
(2ZR-FXE engine) or S (M20A-FXS engine).
• The brake pedal is depressed while driving with the shift leve r in D, B
(2ZR-FXE engine) or S (M20A-FXS engine).
● While the GPF system (P. 529) is operating to regenerate the exhaust gas
filter, the hybrid battery (traction battery) may not be rechar ged.
■ EV indicator
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions*:
● During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● When the temperature of the hybrid battery (traction battery) is high or low
● When the heater is switched on
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
■ Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction bat tery), the bat-
tery does not need to be charged from an outside source. Howeve r, if t h e
vehicle is left parked for a long time the hybrid battery (trac tion battery) will
slowly discharge. For this reason, be sure to drive the vehicle at least once
every few months for at least 30 minutes or 16 km (10 miles). If the hybrid
battery (traction battery) becomes fully discharged and you are unable to start
the hybrid system, contact any authorized Toyota retailer or To yota authorized
repairer, or any r eliable repairer.
The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

NOTICE
■Hybrid battery (traction battery) air intake vent
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. The hybrid battery (traction battery) may
overheat and be damaged.
● When dust, etc., has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction b attery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction batt ery), the battery
may be damaged. Have the vehicle inspected by any authorized To yota
retailer or Toyota authorized repairer, or any reliable repaire r.
● There is a filter installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filte r cleaning or
replacement is recommended. For information regarding filter cl eaning or
replacement, refer to P. 638.
● If “Maintenance required for Traction battery cooling parts. See owner’s
manual.” is shown on the multi-information display, the air int ake vent and
filter may be clogged. Refer to P. 638 for information on how t o clean the
air intake vent.

GPF (Gasoline Par ticulate Filter) system
■If “Exhaust filter full. See owner’s manual.” is shown on the multi-infor-
mation display
● The message may be displayed while high load driving with particulate mat-
ter accumulating.
● Hybrid system output (engine speed) is restricted when a certain amount of
particulate matter accumulates, however, it is possible to driv e the vehicle
unless the malfunction indicator lamp comes on.
● Particulate matter can accumulate more quickly if the vehicle is frequently
driven short trips or at low s peeds, or if the hybrid system is regularly started
in an extremely cold environment. Excessive accumulation of par ticulate
matter can be prevented by periodically driving long distances continuously
with intermittent releasing of the accelerator pedal, such as w hen driving on
highways and freeways.
■ If the malfunction indicator lamp comes on or “Engine Maintenance
Required. Visit Your Dealer.” is shown on the multi-information display
The amount of accumulated particulate matter has exceeded a cer tain level.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reli able repairer immediately.
The GPF system collects particulate matter in the exhaust gas
by using an exhaust gas filter.
The system will operate to regenerate the filter automatically,
depending on the vehicle conditions.
NOTICE
■ To prevent the GPF system from not operating properly
● Do not use fuel other than the specified type
● Do not modify the exhaust pipes

Interior features
■nanoe™ *1 (if equipped)
This vehicle incorporates a biocidal product.
Ionised air generated by a device incorporated in the vehicle p urifies the air in
the cabin by suppressing bacteria.
Active substance: Free radicals generated in situ from ambient air or water
The air conditioning system adopts nanoe™ technology. This help s to fill the
cabin with refreshing air by emitting slightly acidic nanoe™ co ated with water
particles through the passenger’s side vent*2.
● When the fan is turned on, nanoe™ system is activated.
● When the fan is operated in the following conditions, system performance
will be maximized. If the following conditions are not met, nan oe™ may not
operate at full capacity.
• The upper body, the upper body and feet or the feet air outlet s are being
used. ( P. 547)
• The passenger’s side vent is open.
● When nanoe™ is generated, a small amount of ozone is emitted and may
be faintly smelled in some situations. However, this is approxi mately the
same as the amount that already exists in nature, such as in fo rests, and it
has no affect on the human body.
● A slight noise may be heard during operation. This is not a malfunction.
*1: nanoe™ and the nanoe™ mark are trademarks of Panasonic Corporation.
*2: According to temperature and humidity conditions, fan speed and direction
of the air flow, nanoe™ may not operate at full capacity.

Maintenance and care
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear
due to dirt in the air.
■ If the brake fluid level is low or high
It is normal for the brake fluid level to go down slightly as t he brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a se rious problem.
