sway) increases as speed
increases. Exceeding speed
limits may cause loss of con-
trol.
 Before starting out, check the
trailer lights, tires and the
vehicle-trailer connections.
Recheck after driving a short
distance.
 Practice turning, stopping and
reversing with the trailer
attached in an area away
from traffic until you become
accustomed to the feel of the
vehicle-trailer combination.
 Reversing with a trailer
attached is difficult and
requires practice. Grip the
bottom of the steering wheel
and move your hand to the
left to move the trailer to the
left. Move your hand to the
right to move the trailer to the
right. (This is generally oppo-
site to reversing without a
trailer attached.) Avoid sharp
or prolonged turning. Have
someone guide you when
reversing to reduce the risk of
an accident.
 As stopping distance is
increased when towing a
trailer, vehicle-to-vehicle dis-
tance should be increased.
For each 10 mph (16 km/h) of
speed, allow at least one
vehicle and trailer length.
 Avoid sudden braking as you
may skid, resulting in the trailer jackknifing and a loss of
vehicle control. This is espe-
cially true on wet or slippery
surfaces.
 Avoid jerky starts or sudden
acceleration.
 Avoid jerky steering and
sharp turns, and slow down
before making a turn.
 Note that when making a turn,
the trailer wheels will be
closer than the vehicle wheels
to the inside of the turn. Com-
pensate by making a wider
than normal turning radius.
 Slow down before making a
turn, in crosswinds, on wet or
slippery surfaces, etc.
Increasing vehicle speed can
destabilize the trailer.
 Take care when passing other
vehicles. Passing requires
considerable distance. After
passing a vehicle, do not for-
get the length of your trailer,
and be sure you have plenty
of room before changing
lanes.
 Instability happens more fre-
quently when descending
steep or long downhill grades.
Before descending, slow
down and downshift. Do not
make sudden downshifts
while descending steep or
long downhill grades.
 Avoid holding the brake pedal
down too long or applying the

■Automatic hybrid system shut
off feature
●The vehicle is equipped with a
feature that automatically shuts off
the hybrid system when the shift
lever is in P with the hybrid system
operating for an extended period.
●The hybrid system will automati- cally shut off after approximately 1
hour if it has been left running
while the shift lever is in P.
●The timer for the automatic hybrid
system shut off feature will reset if
the brake pedal is depressed or if
the shift lever is in a position other
than P.
●After the vehicle
is parked, if the
door is locked with the door lock
switch ( P.116) from the inside or
the mechanical key ( P.112) from
the outside, the automatic hybrid

NOTICE
■When starting the hybrid sys-
tem
If the hybrid system becomes diffi-
cult to start, have your vehicle
checked by your Toyota dealer
immediately.
■Symptoms indicating a mal-
function with the power
switch
If the power switch seems to be
operating somewh at differently
than usual, such as the switch
sticking slightly, there may be a

■Stopping the hybrid system
in an emergency
●If you want to stop the hybrid
system in an emergency while
driving the vehicle, press and
hold the power s witch for more
than 2 seconds, or press it
briefly 3 times or more in suc-
cession. ( P.494)

ing the hybrid s ystem off while
driving will not cause loss of
steering or braking control, but
the power assist to these sys-
tems will be lost. This will make
it more difficult to steer and
brake, so you should pull over
and stop the vehicle as soon as
it is safe to do so.
●If the power switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-information display
and a buzzer sounds.

WARNING
●To restart the hybrid system

shutdown, shift the shift lever to
N and then press the power
switch.
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the
hybrid system.
●Do not leave the vehicle with
the hybrid system operating for
a long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the vehicle interior.
●Do not leave the hybrid system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the hybrid sys-
tem is operating, exhaust gases
may collect and enter the vehi-
cle.
