■Parking brake operation
●When the engine switch is not in the “ON” position (vehicles with\
out a smart
key system) or IGNITION ON mode (vehicles with a smart key system), the
parking brake cannot be released using the parking brake switch.
● When the engine switch is not in the “ON” position (vehicles with\
out a smart
key system) or IGNITION ON mode (vehicles with a smart key system),
automatic mode (automatic brake setti ng and releasing) is not available.
■ Automatic release function
The parking brake is automatically released when slowly depress the acceler-
ator pedal.
The parking brake will be released automatically under the following condi-
tions:
●The driver’s door is closed.
● The driver’s seatbelt is fastened.
● Shift the shift lever is in a forward or reverse position.
● The malfunction indicator lamp or brake system warning light is not illumi-
nated.
If the automatic release function does not operate, manually release the park-
ing brake.
■ If “EPB Frequently Operated, Wait a Minute.” is displayed on the
multi-information display
If the parking brake is operated repeatedly over a short period of time, the
system may restrict operation to prevent overheating. If this happens, refrain
from operating the parking brake. Normal operation will return after about 1
minute.
■ If “EPB Activation Incomplete.” or “E PB Unavailable” is displayed on the
multi-information display
Operate the parking brake switch. If the message does not disappear after
operating the switch several times, the system may be malfunctioning. Have
the vehicle inspected by your Toyota dealer immediately.
■ Parking brake operation sound
When the parking brake operates, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.

C-HR_OM_USA_OM10526U■
EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● Vehicles without a smart key system: When the engine switch is turned to
the “LOCK” position
Vehicles with a smart key system: When the engine switch is turned off
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine of\
f. The
EPS system should return to normal within 10 minutes.

backward on an upward incline).
● The vehicle is stopped.
● The accelerator pedal is not depressed.
● The parking brake is not engaged.
