Theft deterrent panic mode

When 

 is pressed for longer 

than about one second, an alarm 
will sound intermittently and the 
vehicle lights will flash to deter any 
person from trying to break into or 
damage your vehicle.
To stop the alarm, press any button 

on the electronic key.

To take out the mechanical key, 
slide the release lever   and 
take the key out.

The mechanical key can only be 
inserted in one direction, as the key 
only has grooves on one side. If the 
key cannot be inserted in a lock cyl-
inder, turn it over and re-attempt to 
insert it.
After using the mechanical key, 
store it in the electronic key. Carry 
the mechanical key together with 
the electronic key. If the electronic 
key battery is depleted or the entry 
function does not operate properly, 
you will need the mechanical key.

Rear seat reminder function

●

In order to remind you not to for-

get luggage, etc., in the rear seat, 

when the power switch is turned to 

OFF after any of the following con-

ditions are met, a buzzer will 

sound and a message will be dis-

played on the multi-information 

display for approximately 6 sec-

onds.

• The hybrid system is started 

within 10 minutes after opening 

and closing a rear door.

• A rear door has been opened and 

closed after the hybrid system 

was started.

However, if a rear door is opened 
and then closed within approxi-
mately 2 seconds, the rear seat 
reminder function may not operate.

●

The rear seat reminder function 

determines that luggage, etc., has 

been placed in a rear seat based 

on opening and closing of a rear 

door. Therefore, depending on the 

situation, the rear seat reminder 

function may not operate and you 

may still forget luggage, etc., in 

the rear seat, or it may operate 

unnecessarily.

●

The rear seat reminder function 

can be enabled/disabled.

WARNING

■

Cautions regarding the power 

running boards

Observe the following precau-

tions.

Failure to do so may cause seri-

ous injury.

●

Check to make sure that all pas-

sengers and people in the vehi-

cle’s surrounding area do not 

have a hand on the boards or 

any part of their body in a posi-

tion where it could be caught 

between the boards and the 

vehicle when the power running 

boards is being operated.

●

Confirm that the boards have 

completely deployed or stowed 

before getting in or out of the 

vehicle. If someone gets in or 

out of the vehicle during the 

power running boards opera-

tion, the boards may stop 

deploying or stowing.

●

Take care when pressing the 

power steps switch. The boards 

will deploy or stow and may hit 

other people or objects.

■

Jam protection function

If a board contacts an obstacle 

when deploying, it will stow. If an 

obstacle gets caught between a 

board and the vehicle when stow-

ing, the board will deploy.
If an obstacle is detected 3 times in 

a row during power running board 

operation, the board will stop at the 

position it contacts the obstacle. 

When the side door on the same 

side as the board is opened and 

closed, or switch is operated once 

the obstacle is cleared, the board 

will attempt to stow or deploy again.

■

Automatic stowing function

The boards will be automatically 

stowed, for safety, under the follow-

ing conditions:

WARNING

●

Always check that the power 

steps switch is turned off when 

cleaning the boards, before 

jacking up or placing any object 

under the vehicle, or if boards 

are not operating correctly.

●

Do not allow children to operate 

the power running boards. 

Operating the power running 

boards so that the boards con-

tacts someone can cause seri-

ous injury, and in some 

instances, even death.

■

Jam protection function

Observe the following precau-

tions.

Failure to do so may cause seri-

ous injury.
Do not place any body part 

between the boards and vehicle.

ning boards are not operating 

correctly, turn the power steps 

switch off and refrain from use.

■

After recharging/reconnecting 

the 12-volt battery

If the power running boards have 

not completely deployed or stowed, 

the boards may not move in the 

intended direction the first time they 

are operated. However, from the 

second time onwards, the boards 

will resume normal operation.

■

WARNING

■

Cautions regarding the power 

bed step

Observe the following precau-

tions. Failure to do so may cause 

serious injury.

●

Check to make sure that all pas-

sengers and people in the vehi-

cle’s surrounding area do not 

have a hand on the step or any 

part of their body in a position 

where it could be caught 

between the step and the vehi-

cle when the power bed step is 

being operated.

●

Confirm that the step has com-

pletely deployed or stowed 

before getting in or out of the 

vehicle. If someone gets in or 

out of the vehicle during power 

bed step operation, the step 

may stop deploying or stowing.

●

Take care when pressing the 

power steps switch. The step 

will deploy or stow and may hit 

other people or objects.

●

Always check that the power 

steps switch is turned off when 

cleaning the step, before jack-

ing up or placing any object 

under the vehicle, or if the step 

is not operating correctly.

●

Do not allow children to operate 

the power bed step. Operating 

power bed step so that a step 

contacts someone can cause 

serious injury, and in some 

instances, even death.

■

Jam protection function

Observe the following precau-

tions. Failure to do so may cause 

serious injury.
Do not place any body part 

between the power bed step and 

vehicle. The jam protection func-

tion may not work depending on 

the shape of the object that is 

caught.
