TOYOTA SIENNA HYBRID 2021 Owners Manual (in English)

2003-4. Adjusting the steering wheel and mirrors
R).
■Adjusting the mirror angle
when the vehicle is revers-
ing
With the shift lever in R, adjust
the mirror angle at a desired
position. The adjusted angle will
be memorized and the mirror
will automatically tilt to the mem-
orized angle whenever the shift
lever is shifted to R from next
time.
The memorized downward tilt
position of the mirror is linked to
the normal position (angle
adjusted with the shift lever in
other than R). Therefore, if the
normal position is changed after
adjustment, the tilt position will
also change.
When the normal position is
changed, readjust the angle in
reversing.

■When starting off on a uphill
The hill-start assist control will acti-
vate. ( P.335)
■For fuel-efficient driving
Keep in mind that hybrid vehicles
are similar to conventional vehicles,
and it is necessary to refrain from
activities such as sudden accelera-
tion, etc. Refer to “Hybrid vehicle
driving tips”. ( P.341)
■Driving in the rain
●Drive carefully whe n it is raining,
because visibility will be reduced,
the windows may become fogged-
up, and the road could be slip-

pery.
●Drive carefully when it starts to
rain, as the road surface could be
especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.
■ECO Accelerator Guidance
(  P.108)
It is easier to drive in an Eco-friendly
manner by driving while referring to
the ECO Accelerator Guidance dis-
play. Also, by using the ECO Accel-
erator Guidance it is easier to
increase the “Eco Score” evaluation.
●When starting off:
While staying within the ECO
Accelerator Guidance range,
gradually depress the accelerator
pedal and accelerate to the
desired speed. If excessive accel-
eration is avoid ed, the “Start”
score will increase.
●When driving:
After accelerating to the desired
speed, release the accelerator
pedal and drive at a stable speed
within the ECO Acce lerator Guid-
ance range. By keeping the vehi-
cle within the E CO Accelerator
Guidance range, the “Cruise”
score will increase.
●When stopping:
When stopping the vehicle, early
releasing the accelerator pedal
will cause the “Stop” score to
increase.
■Restraining the hybrid system
output (Brake Override System)
●When the accelerator and brake
pedals are depressed at the same
time, the hybrid system output
may be restrained.
●A warning message is displayed
on the multi-information display
and head-up display (if equipped) while the system is operating.
(
 P.471)
■Restraining sudden start (Drive-
Start Control)
●When the following unusual oper-
ation is performed, the hybrid sys-
tem output may b e restrained.
• When the shift lever is shifted from
R to D, D to R, N to R, P to D
*, or
P to R* (D includes S) with the
accelerator pedal depressed, a
warning message appears on the
multi-information display and
head-up display (i f equipped). If a
warning message is shown on the
multi-information display and
head-up display (if equipped),
read the message and follow the
instructions.
• When the accelerator pedal is depressed too much while the
vehicle is in reverse.
*: Depending on the situation, the
shift position may not be changed.
●When the TRAC is turned off
( P.336), sudden start restraint
control also does not operate. If
your vehicle have trouble escap-
ing from the mud or fresh snow
due to the sudden start restraint
control operation, deactivate
TRAC( P.336) so that the vehi-
cle may become able to escape
from the mud o r fresh snow.
