The installation of a mobile two-way radio system in your vehicle could affect
electronic systems such as:
● Multiport fuel injection system/sequential multiport fuel injection system
● Toyota Safety Sense P (if equipped)
● Dynamic radar cruise control system (if equipped)
● Cruise control system (if equipped)
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Toyota dealer for precautionary meas ures or spe-
cial instructions regarding instal lation of a mobile two-way radio system.
The vehicle is equipped with sophisticated computers that will record certain
data, such as:
The recorded data varies according to the vehicle grade level and options
with which it is equipped
These computers do not record conversations or sounds, and only record
images outside of the vehicle in certain situations.
• Engine speed / Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems, such as the AB S and pre-
collision system
• Images from the camera (available only when certain safety sys tems are
activated, which varies depending on the vehicle specifications).
●Data Transmission
Your vehicle may transmit the data recorded in these computers to Toyota
without notification to you.

2144-1. Before driving
WARNING
■Trailer towing precautions
To tow a trailer safely, use extreme care and drive the vehicle in accordance
with the trailer’s characteristics and operating conditions. Failure to do so
could cause an accident resulting in death or serious injury. V ehicle stability
and braking performance are affected by trailer stability, brak e setting and
performance, and the hitch. Your vehicle will handle differentl y when towing
a trailer.
■ To avoid accident or injury
● Do not exceed the TWR, unbraked TWR, GCWR, GVWR or GAWR.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway control device
with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weigh t distributing
hitch with sufficient capacity is required.
● Adjust the tongue weight within the appropriate range. Place he avier loads
as close to the trailer axle as possible.
● Do not exceed 65 mph (104 km/h), the posted towing speed limit or the
speed limit for your trailer as set forth in your trailer owner ’s manual,
whichever is lowest. Slow down sufficiently before making a turn, in cross-
winds, on wet or slippery surface, etc., to help avoid an accident. If you
experience a vehicle-trailer instability from reducing a certai n speed, slow
down and make sure you keep your vehicle speed under the speed of
which you experience the instability.
● Do not make jerky, abrupt or sharp turns.
● Do not apply the brakes suddenly as you may skid, resulting in jackknifing
and loss of vehicle control. This is especially true on wet or slippery sur-
faces.
● Do not exceed the trailer hitch assembly weight, gross vehicle weight,
gross axle weight and trailer tongue weight capacities.
● Do not use cruise control when towing.
● Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts while descending steep or long
downhill grades.
● Vehicle-trailer instability is more likely on steep long downhi lls. Before
descending steep or long downhill grades, slow down and downshi ft. Do
not make sudden downshifts when descending steep or long downhi ll
grades. Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and result
in reduced braking efficiency.
● Do not tow a trailer when the temporary spare tire is installed on your vehi-
cle.

Driving
■AI-SHIFT
AI-SHIFT automatically selects the suitable gear according to t he driver per-
formance and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position.
(Shifting the shift lever to the S position cancels the functio n.)
■ When driving with cruise cont rol activated (if equipped)
Even when performing the following actions with the intent of e nabling engine
braking, engine braking will not activate while driving in S mo de and down-
shifting to 5 or 4 because cruise control will not be canceled. (P. 280 294)
■ Shift lock system
The shift lock system is a system to prevent accidental operation of the shift
lever in starting.
The shift lever can be shifted from P only when the engine swit ch is in ON
and the brake pedal is being depressed.
■ If the shift lever cannot be shifted from P
First, check whether the brake pedal is being depressed.
If the shift lever cannot be shifted with your foot on the brak e pedal, there may
be a problem with the shift lock system. Have the vehicle inspected by your
Toyota dealer immediately.
The following steps may be used as an emergency measure to ensu re that
the shift lever can be shifted.
Releasing the shift lock:
Set the parking brake.
Turn the engine switch to OFF.
Depress the brake pedal.

WARNING
■ Toyota Safety Sense P
The Toyota Safety Sense P is designed to operate under the assu mption
that the driver will drive safely, and is designed to help redu ce the impact to
the occupants and the vehicle in the case of a collision or ass ist the driver in
normal driving conditions.
As there is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicl e’s surround-
ings and driving safely.
