■When the indicator turns on
Indicates a malfunction in the air
suspension system.
Have the vehicle inspected by your
Toyota dealer immediately. ( P.89,

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 yo ur 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 ma y be damaged.

trailer according to the dis-
play. 2
Press the switch to turn the
system ON.
3 Continue or reselect the
trailer in the message dis-
played on the multi-informa-
tion display.
When the selected trailer is being
used for the first time, setup (cali-
bration) is nece ssary (→P.392).
Once calibration is completed, it is
retained for future use and the sys-
tem will automatically detect the
trailer.
The driver needs to change the
trailer selection when using a differ-
ent trailer. The system does not
automatically recognize the trailer
from the saved trailers list.
4 Once trailer is detected, shift
the shift lever to R to activate
Guidance mode.
5 Touch the switch at the bot-
tom right on multimedia to

Trailer Backup Guide*
Trailer Backup Guide is a
system to assist when back-
ing up a trailer by providing
either (1) steering control to
assist backing up straight
(Straight Path Assist) or (2)
guidance for manual steer-
ing backup (Guidance
mode).
Trailer Backup Guide uses
the rear camera to detect
the trailer and a trailer hitch
light, which allows the
driver to use the system at
night time.
The system calculates the
trailer angle by image pro-
cessing from the rear cam-
era and calculates trailer
length and hitch length
during the trailer setup (cali-
bration) maneuver.

●For best calibration results, cali-
brate in daytime on a smooth and
level road.
●It may be necessary at times to re-
calibrate the trailer to improve per-
formance.
●The system is designed to be
used with the same trailer connec-
tion every time. If the ball mount
position is changed or reconfig-
ured or items are added to the
trailer tongue
after calibration, re-
calibration may be required.
Guidance mode provides a
“Trailer Direction” arrow that
indicates the direction the trailer
will swing, based on calculations
from the steering wheel angle
information. Guidance mode
provides a “BRAKE Extreme
Trailer Angle” (jackknife) warn-
ing with warning buzzer to alert
the driver that the trailer angle is
near the jackknife condition.

When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. (P.366)
The Eco-friendly driving is pos-
sible by keeping the indicate of
Hybrid System Indicator within
Eco area. ( P.99)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. When using the air condi-
tioning system, etc., the hybrid
battery (traction battery) power
is consumed. 
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic
reports before leaving and avoid
delays as much as possible.
When driving in a traffic jam,
gently release the brake pedal

overuse of the accelerator
pedal. Doing so can help control
excessive gasoline consump-
tion.
Control and maintain the vehicle
at a constant speed. Before
stopping at a toll booth or simi-
lar, allow plenty of time to
release the accelerator and gen-
tly apply the brakes. A greater
amount of electrical energy can
be regenerated when slowing
down.
Use the air conditioning only
when necessary. Doing so can
help reduce excessive gasoline
consumption.
In summer: When the ambient
temperature is high, use the
recirculated air mode. Doing so
will help to reduce the burden on
the air conditioning system and
reduce fuel consumption as
well.
In winter: Because the gasoline
engine will not automatically cut
out until it and the interior of the
vehicle are warm, it will con-
sume fuel. Also, fuel consump-
tion can be improved by
avoiding overuse of the heater. Make sure to check the tire infla-
tion pressure frequently.
Improper tire inflation pressure
can cause poor fuel economy.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
poor fuel economy. Use tires
that are appropriate for the sea-
son.
Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically
when cold, warming up the
engine is unnecessary. More-
over, frequently driving short
distances will cause the engine
to repeatedly warm up, which
can lead to excess fuel con-
sumption.
