Emergency flashers

●

If the emergency flashers are 

used for a long time while the 

hybrid system is not operating 

(while the “READY” indicator is 

not illuminated), the 12-volt bat-

tery may discharge.

●

If any of the SRS airbags deploy 

(inflate) or in the event of a strong 

rear impact, the emergency flash-

ers will turn on automatically. 

The emergency flashers will turn 

off automatically after operating 

for approximately 20 minutes. To 

manually turn the emergency 

flashers off, press the switch 

twice. 

(The emergency flashers may not 

turn on automatically depending 

on the force of the impact and 

conditions of the collision.)

Emergency flashers

The emergency flashers are 
used to warn other drivers 
when the vehicle has to be 
stopped on the road due to 
a breakdown, etc.

8-1. Essential information



Remove the seat belt first.



If the door can be opened, 
open the door and exit the 
vehicle.



If the door can not be opened, 
open the window using the 
power window switch and exit 
the vehicle through the win-
dow.



If the window can not be 
opened using the power win-
dow switch, remain calm, wait 
until 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 
and exit the vehicle.

If the vehicle is 

trapped in rising water

In the event the vehicle is 
submerged in water, remain 
calm and perform the fol-
lowing.

WARNING

■

Using an emergency hammer

*

 

for emergency escape

The front side windows and rear 

side windows, as well as the rear 

window can be shattered with an 
emergency hammer

*

 used for 

emergency escape. However, an 
emergency hammer

*

 can not 

shatter the windshield as it is lam-

inated glass.

*

: Contact your Toyota dealer or 

aftermarket accessory manu-
facturer for further information 
about an emergency hammer.

■

Escaping the vehicle from the 

window

There are cases where escaping 

the vehicle from the window is not 

possible due to seating position, 

passenger body type, etc. 

When using an emergency ham-

mer, consider your seat location 

and the size of the window open-

ing to ensure that the opening is 

accessible and large enough to 

escape.

8-2.Steps to take in an emergency

If your vehicle needs 

to be towed

If towing is necessary, we 
recommend having your 
vehicle towed by your Toy-
ota dealer or commercial 
towing service, using a 
wheel-lift type truck or flat-
bed truck.

Use a safety chain system 
for all towing, and abide by 
all state/provincial and local 
laws.

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.

■

While towing

●

When towing using cables or 

chains, avoid sudden starts, etc. 

which place excessive stress on 

the towing eyelets, cables or 

chains. The towing eyelets, 

cables or chains may become 

damaged, broken debris may hit 

people, and cause serious dam-

age.

●

Do not turn the power switch off.

There is a possibility that the 

steering wheel is locked and 

cannot be operated.

■

Installing towing eyelets to 

the vehicle

Make sure that towing eyelets are 

installed securely.

If not securely installed, towing 

eyelets may come loose during 

towing.

NOTICE

■

To prevent damage to the 

vehicle when towing using a 

wheel-lift type truck

●

Do not tow the vehicle from the 

rear when the power switch is 

off. The steering lock mecha-

nism is not strong enough to 

hold the front wheels straight.

●

When raising the vehicle, 

ensure adequate ground clear-

ance for towing at the opposite 

end of the raised vehicle. With-

out adequate clearance, the 

vehicle could be damaged while 

being towed.

■

To prevent damage to the 

vehicle when towing with a 

sling-type truck

Do not tow with a sling-type truck, 

either from the front or rear.

446

8-2. Steps to take in an emergency

The following may indicate a 
problem with your transmission. 
Contact your Toyota dealer or 
commercial towing service 
before towing.


The hybrid system warning 
message is shown on the 
multi-information display and 
the vehicle does not move.



The vehicle makes an abnor-
mal sound.

Do not tow with a sling-type 
truck to prevent body damage.



From the front

Release the parking brake.



From the rear

Use a towing dolly under the 
front wheels.

If your vehicle is transported by 
a flatbed truck, it should be tied 
down at the locations shown in 
the illustration.

NOTICE

■

To prevent damage to the 

vehicle during emergency 

towing

Do not secure cables or chains to 

the suspension components.

essary to contact dealers

If you use chains or cables to tie 
down your vehicle, the angles 
shaded in black must be 45°.
Do not overly tighten the tie 
downs or the vehicle may be 
damaged.

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. This 
should only be attempted on 
hard surfaced roads for a short 
distance at under 18 mph (30 
km/h).
A driver must be in the vehicle to 
steer and operate the brakes. 
The vehicle’s wheels, drive train, 
axles, steering and brakes must 
be in good condition.

1

Take out the towing eyelet. 
(P.464, 474)

2

Remove the eyelet cover 
using a flathead screwdriver.

To protect the bodywork, place a 

rag between the screwdriver and 

the vehicle body as shown in the 

illustration.

Insert the towing eyelet into 
the hole and tighten partially 
by hand.

assist for the brakes and steering 

will not function, making steering 

and braking more difficult.

with a spare tire)

Wheel nut wrench is installed in 

trunk. (P.474)



Fluid leaks under the vehicle.
(Water dripping from the air 
conditioning after use is nor-
mal.)

Engine coolant temperature 
gauge needle continually 
points higher than normal.



Changes in exhaust sound
