■E-Four (Electronic On-Demand
AWD system)
Automatically switches from front
wheel drive to all-wheel drive
(AWD) according to the driving con -
ditions, helping to ensure reliable
handling and stability. Examples of
conditions where the system will
switch to AWD are when cornering,
going uphill, start ing off or acceler-
ating, and when the road surface is
slippery due to snow, rain, etc.
■Emergency brake signal

denly, the emergency flashers
automatically flash to alert the vehi -
cle behind.
■The Secondary Collision
Brake (if equipped)

detects a collision and the system
operates, the brakes and brake
lights are automatically controlled
to reduce the v ehicle speed and
help reduce the possibility of further
damage due to a secondary colli -
sion.
■When the TRC/VSC/ABS/Trailer Sway Control syst ems are operat-
ing
The slip indicator light will flash while the TRC/VSC/ABS/Traile r Sway Control

■Operating conditions of Active Cor -
nering Assist
The system operates when the following occurs.
●TRC/VSC can operate
●The driver is attempting to accelerate
while turning

■Reduced effectiveness of the EPS
system
The effectiveness o f 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 t urn the hybrid sys-
tem off. The EPS sys tem should return to normal within 10 minutes.

brake signal
When the following co nditions are met, the emergency brake signal will operate:
●The emergency fl ashers are off.
●Actual vehicle speed is over 55 km/h
(35 mph).

deceleration that it is a sudden brak -
ing operation.
■Automatic system cancelation of emergency brake signal
The emergency brake signal will be can -
celed in any of the following situations:
●The emergency flashers are turned
on.
●The system judges from the vehicle
deceleration that is not a sudden brak - ing operation.
■Secondary Collision Brake operat -
ing conditions (if equipped)
The system operates when the SRS air - bag sensor detects a collision while the
vehicle is in moti on. However, the sys-
tem does not operate in any of the fol - lowing situations.
●The vehicle speed is below 10 km/h (6 mph)
●Components are damaged
■Secondary Collision Brake auto - matic cancellation (if equipped)
The system is automa tically canceled in
any of the following situations.

5828-2. Steps to take in an emergency
Stop the vehicle in a safe place
on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P.
 Turn off the intrusion sensor and
tilt sensor (if equipped) ( →P.79)
 Stop the hybrid system.
 Turn on the emergency flashers.
( →P.560)
 For vehicles with power back
door: Turn off the power back

 Check the degree of the tire
damage.
A tire should only be repaired with
the emergency tire puncture repair
kit if the damage is caused by a nail
or screw passing through the tire
tread.
• Do not remove the nail or screw
from the tire. Removing the
object may widen the opening
and prevent emergency repair
with the repair kit.
• To avoid sealant leakage, move
the vehicle unt il the area of the
puncture, if known, is positioned
at the top of the tire.
If you have a flat tire
(vehicles without spare
tire)
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo -
rarily using the emergency tire
puncture repair kit. (The kit
contains a bottle of sealant.
The sealant can be used only
once to temporarily repair one
tire without removing the nail
or screw from the tire.)
