WARNING

■

The electronically modulated

air suspension must be

turned off in the following cir-

cumstances:

Otherwise, the automatic leveling

function may cause the vehicle’s

height to change, and you may

catch part of your body in the

vehicle, resulting in an unex-

pected accident or injury:

●

When driving through water

such as shallow streams (Put

the vehicle height in “HI” mode

and turn off the electronically

modulated air suspension. Drive

at 18 mph [30 km/h] or slower.)

●

When jacking up the vehicle,

installing tire chains or tying the

vehicle with chains/wires for

transportation via flat bed truck

(Turn the system to the manual

mode and stop the hybrid sys-

tem.)

●

When the vehicle must be

towed (Put the vehicle height in

“N” mode and turn the system to

the manual mode.)

●

When the vehicle gets stuck

(Turn the system to the manual

mode.)

●

When disconnecting a trailer

(Put the vehicle height in “N”

mode and turn the system to the

manual mode.)

■

Selecting the correct height

mode

Observe the following precautions

to prevent accidents or injury.

Failure to do so may cause dam-

age to parts of the vehicle, as well

as dangerous handling character-

istics, which may lead to fatal or

injury accidents.

●

Before you lower the vehicle’s

height, check under the vehicle

to make sure that no one is

there.

●

“HI” mode should only be used

when driving on rough roads, for

example when driving off-road.

Because the vehicle’s center of

gravity will become higher when

in the mode, the vehicle may

become unstable when turning

abruptly, resulting in an acci-

dent.

●

Do not select “HI” mode when

you load cargo on the roof lug-

gage carrier.

Because the vehicle’s center of

gravity will become higher when

in the mode, the vehicle may

become unstable when turning

abruptly, resulting in an acci-

dent.

NOTICE

■

Be careful in any place where

overhead space is limited.

When changing to a higher mode

or after unloading, the vehicle

height will rise. This may cause

damage to the vehicle.

■

Do not select “LO” mode

when driving on bumpy

roads.

If the underbody of the vehicle

touches a rugged road surface,

the vehicle may be damaged.
