Hybrid transaxle
Your hybrid transaxle has an electronic
shift lever system to minimize incorrect
operation. This means you can only shift
to other position from “P” when the brake
pedal is depressed.
With the following improper shifting, the
rejection function operates and a beep
sounds so the hybrid transaxle cannot be
shifted.(i) When you attempt to shift the transaxle from the “P” position without depress-
ing the brake pedal.
(ii) When you push the “P” switch while driving.
(iii) When you operate the shift lever from “D” to “R” or vice versa while the ve-
hicle is moving.
(iv) When you operate the shift lever to “B” from any position other than “D”.
In case of (i), the transaxle remains in
“P”. In case of (ii) through (iv), the trans-
axle is automatically shifted to “N”.
25p002i
Shift lever
The shift lever always re-
turns to this original position
after shifting operation. “P” position switch
You can operate the shift
lever only in “D”.
Keep the shift lever in “N”
for a while after you shift it
to that position.

(a) Shift lever
The shift position is displayed on the in-
strument cluster.
R:Reverse position (buzzer sounds)
N: Neutral position
D: Normal driving position
B: Engine braking position
(shown only while in “D”)
NOTICE
Observe the following instructions.
Otherwise, the lever may cause a mal-
function, resulting in trouble:
Do not remove the knob on the le-
ver.
 Do not use a knob other than the
originally fitted knob.
 Do not hang anything on the lever.
Should you find anything unusual,
contact your Toyota dealer as soon as
possible.
(b) “P” position switch
The “P” (parking) position is displayed on
the instrument cluster, and the indicator
on the “P” position switch comes on.
(c) Normal driving 1. Start the hybrid system as instructed in “How to start the hybrid system” on
page 348.
2. With your foot holding down the brake pedal, shift the shift lever to “D”.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting. Doing so can
cause abrupt acceleration.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
When you shift the transaxle to “D”
while backing up, an alarm sounds and
the transaxle is shifted to “N”.

25p004c
(d) Using engine braking
To use engine braking, shift the shift lever
to “B” position.
During high speed driving, you may feel
that deceleration by engine braking is less
than that of a typical vehicle.
Do not continue normal driving with the
transaxle in “B” for a long time. This may
cause decreased fuel economy. To prevent
this, use “D” for normal driving.
When you shift the transaxle to “B” from
a position other than “D”, an alarm sounds
and the transaxle is automatically shifted
to “N”.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to skid or
spin.
(e) Backing up1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the shift lever to the
“R” position. You will hear beeps while
the transaxle is in “R”.
When you shift the transaxle to “R” while
driving, an alarm sounds and the transaxle
is shifted to “N”.
(f) Parking 1. Bring the vehicle to a complete stop.
2. With the brake pedal pressed down, fully depress the parking brake pedal
to apply the parking brake securely.
3. With the brake pedal pressed down, push the “P” position switch.
If you press the “POWER” switch while
stopping, the transaxle is automatically
shifted to the “P” and the hybrid system
is turned off. If the driver ’s door is opened when the
transaxle is in “N”, “D” or “B”, beep
sounds and a warning message appears
on the multi
−information display to warn
you to shift the transaxle to “P”.
If you push the “P” position switch while
driving, an alarm sounds and the transaxle
is automatically shifted to “N”.NOTICE
Be sure to put the hybrid transaxle in
“P” when parking. In “N”, the hybrid
battery will not be charged even if the
gasoline engine is running. You can-
not start your vehicle if the transaxle
is left in “N” for a long time because
the hybrid battery will discharge.
When shifting the transaxle from “P” on
the slope, a large parking lock releasing
noise will be generated. However, this
does not indicate a malfunction.

The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, brake assist system, hybrid system
control, etc. This system automatically
controls the brakes and hybrid system
to help prevent the vehicle from skid-
ding when cornering on a slippery road
surface or operating steering wheel
abruptly.
This system activates when the vehicle
speed is more than about 15 km/h (9
mph).CAUTION
Do not rely exclusively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid death or serious injury. Reck-
less driving will result in an unex-
pected accident. If the slip indicator
light flashes, sounding an alarm,
special care should be taken while
driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use tires other than
specified, or mixed types or size,
the vehicle stability control system
may not function correctly. When
replacing the tires or wheels, con-
tact your Toyota dealer. (See
“Checking and replacing tires” on
page 407.)
25p115a
Slip indicator light
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light blinks in the follow-
ing conditions also.
The vehicle tires are racing. Utmost
care is required when driving.
When the anti−lock brake system is
operating. See “Brake system” on page
325 for details.
