■When starting off on a uphill
The hill-start assis t control will acti-
vate. ( P.307)
■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 will be
slippery.
●Drive carefully whe n it starts to
rain, because the road surface will
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.
■Engine speed while driving
In the following conditions, the
engine speed may become high
while driving. This is due to auto-
matic up-shifting control or
down-shifting implementation to
meet driving conditions. It does not
indicate sudden acceleration.
●The vehicle is judged to be driving
uphill or downhill
●When the accelerator pedal is released
●When the bra
ke pedal is
depressed
■Restraining the engine output
(Brake Override System)
●When the accelera tor and brake
pedals are depressed at the same

When the TRAC is turned off
(  P.308), sudden start restraint
control also does not operate. If
your vehicle have trouble escaping
from the mud or fr esh snow due to
sudden start restraint control opera-
tion, deactivate TRAC ( P.308) so
that the vehicle may become able to
escape from the mud or fresh snow.
Also, sudden start restraint control
will not operate in the following con-
ditions:
●When Multi-terrain Select is
selected (AWD models)
■Breaking in your new Toyota
To extend the life of the vehicle,
observing the following precautions
is recommended:
●For the first 200 miles (300 km):

 P.89, 100
WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When starting the vehicle
Always keep your foot on the
brake pedal while stopped with
the engine running. This prevents
the vehicle from creeping.
■When driving the vehicle
●Do not drive if y ou are unfamil-
iar with the location of the brake
and accelerator pedals to avoid
depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the
brake pedal will result in sudden
acceleration that may lead to an
accident.
• When backing up, you may twist your body around, leading to a
difficulty in operating the pedals.
Make sure to operate the pedals
properly.
• Make sure to keep a correct driving posture even when mov-
ing the vehicle only slightly. This
allows you to depress the brake
and accelerator pedals properly.
• Depress the brake pedal using your right foot. Depressing the
brake pedal using your left foot
may delay respon se in an emer-
gency, resulting in an accident.
●Do not drive the vehicle over or
stop the vehicle near flammable
materials.
The exhaust system and
exhaust gases can be
extremely hot. These hot parts
may cause a fire i f there is any
flammable material nearby.
●During normal driving, do not
turn off the engine. Turning the
engine off while driving will not
cause loss of steering or brak-
ing control, but the power assist
to these systems 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.How-
ever, in the event of an emer-
gency, such as if it becomes
impossible to stop the vehicle in
the normal way:
P.424
●Use engine braking (downshift)
to maintain a safe speed when
driving down a steep hill.Using
the brakes continuously may
cause the brakes to overheat
and lose effectiveness.
(
P.201)
●Do not adjust the positions of
the steering wheel, the seat, or
the inside or outside rear view
mirrors while driving.Doing so
may result in a loss of vehicle
control.
●Always check that all passen-
gers’ arms, heads or other parts
of their body are not outside the
vehicle.
●AWD models: This is not an
AWD vehicle designed for
off-road driving. Drive with due
care if it becomes unavoidable
to drive off-road.
