rear impact, the emergency flash-
ers will turn on automatically.
The emergency flashers will turn
off automatically after operating

manually turn the emergency
flashers off, press the switch
twice. (The emergency flashers
may not turn on automatically

stopped in the road due to a
breakdown, etc.

WARNING
■If the hybrid system has to be
turned off while driving
Turning the hybrid system off
while driving will not cause loss of
steering or braking control. How-
ever, power assist for the steering
wheel may be lost making it diffi-
cult to steer smoothly before stop-
ping the vehicle depending on the
remaining charge in the 12-volt
battery or usage conditions.
Decelerate as much as possible
before turning off the hybrid sys-
tem.

open the window using the
power window switch and
ensure an escape route.
 If the window can be opened,
exit the vehicle through the
window.
 If the door and window cannot
be opened due to the rising

the water level inside the
vehicle rises to the point that
the water pressure inside of
the vehicle equals the water
pressure outside of the vehi-
cle and then open the door
after waiting for the rising
water to enter the vehicle, and
exit the vehicle. When the outside water level exceeds
half the height of the door, the
door cannot be opened from

When trouble arises
From the rear
Use a towing dolly under the
front wheels.
When using a flat-bed truck to
transport the vehicle, use tire
strapping belts. Refer to the
owner’s manual of the flat-bed
truck for the tire strapping
method.
In order to suppress vehicle move-
ment during transp ortation, set the
parking brake and turn the power
switch off.
If a tow truck is not available in
an emergency, your vehicle may
be temporarily towed using
cables or chains secured to the
emergency towing eyelets.
WARNING
Observe the following precau-
tions. Failure to do so may result
in death or serious injury.
■When towing the vehicle
Be sure to transport the vehicle
with the front wheels raised or
with all four wheels raised off the
ground. If the vehicle is towed
with the front wheels contacting
the ground, the drivetrain and
related parts may be damaged or
electricity generated by the opera-
tion of the motor may cause a fire
to occur depending on the nature
of the damage or malfunction.
NOTICE
■To prevent damage to the
vehicle when towing using a
wheel-lift type truck
When raising the vehicle, ensure
adequate ground clearance for
towing at the opposite end of the
raised vehicle. Without adequate
clearance, the vehicle could be
damaged while being towed.
■Towing with a sling-type
truck
Do not tow with a sling-type truck
to prevent body damage.
