MessageCauseWhat to do

3784-5. Using the driving support systems
UK_AURIS/AURIS_HV_EE (OM12G88E)Reduced effectiveness of the EPS system
Except hybrid model: The effectiveness of the EPS system is reduced to pre-
vent 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 off. The EPS system should return to normal within 10
minutes.
Hybrid model: 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 hybrid system off. The EPS system should return to normal
within 10 minutes.
Operating conditions of emergency brake signal
When the following three conditions are met, the emergency brake signal will
operate:
The emergency flashers are off.
Actual vehicle speed is over 55 km/h (35 mph).
The brake pedal is depressed in a manner that cause the system to judge
from the vehicle deceleration that this is a sudden braking operation.
Automatic system cancelation of emergency brake signal
The emergency brake signal will turn off in any of the following situations:
The emergency flashers are turned on.
The brake pedal is released.
The system judges from the vehicle deceleration that is not a sudden brak-
ing operation.
CAUTION
The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick roads.

• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping

Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
Do not use seat heater more than necessary. Doing so may cause minor
burns or overheating.
