WARNING
■To avoid accident or injury
● 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 downhills. Before
descending steep or long downhill grades, slow down and downshift. Do
not make sudden downshifts when descending steep or long downhill
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.
● Vehicles with compact spare tire: Do not tow a trailer when the compact
spare tire is installed on your vehicle.
■ Hitch
Trailer hitch assemblies have different weight capacities established by the
hitch manufacturer. Even though the vehicle may be physically capable of
towing a higher weight, the operator must determine the maximum weight
rating of the particular hitch assembly and never exceed the maximum
weight rating specified for the trailer-hitch. Exceeding the maximum weight
rating set by the trailer-hitch manufacturer can cause an accident resulting
in death or serious personal injuries.
■ When towing a trailer
Toyota recommends trailers with brakes that conform to any applicable fed-
eral and state/provincial regulations.
● If the gross trailer weight exceeds unbraked TWR, trailer brakes are
required. Toyota recommends trailers with brakes that conform to all appli-
cable federal and state/provincial regulations.
● Never tap into your vehicle’s hydraulic system, as this will lower the vehi-
cle’s braking effectiveness.
● Never tow a trailer without using a safety chain securely attached to both
the trailer and the vehicle. If damage occurs to the coupling unit or hitch
ball, there is danger of the trailer wandering into another lane.
NOTICE
■When installing a trailer hitch
Use only the position recommended by your Toyota dealer. Do not install
the trailer hitch on the bumper; this may cause body damage.
■ Do not directly splice trailer lights
Do not directly splice trailer lights. Directly splicing trailer lights may damage
your vehicle’s electrical system and cause a malfunction.

Driving
■Shift ranges and their functions
●Automatically selecting gears bet ween 1 and 6 according to vehi-
cle speed and driving conditions. But, the gear is limited accord-
ing to selected shift range.
● You can choose from 6 levels of engine braking force.
● A lower shift range will provide gr eater engine braking force than
a higher shift range, and the engine speed will also increase.
■ S mode
●When the shift range is 5 or lower, holding the shift lever toward “+” sets the
shift range to 6.
● To prevent excessive engine speed, a function was adopted that automati-
cally selects a higher shift range before the engine speed becomes too high.
● To protect the automatic transaxle, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
■ Downshift restriction wa rning buzzer (S mode)
To help ensure safety and driving performance, downshifting operation may
sometimes be restricted. In some circumstances, downshifting may not be
possible even when the shift lever is operated. (A buzzer will sound twice.)
■ When driving with the cr uise control or dynamic radar cruise control
activated (if equipped)
Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate while driving in S mode and down-
shifting to 5 or 4 because cruise control or dynamic radar cruise control will
not be canceled. ( P. 257, 261)
■ If the shift lever cannot be shifted from P
●P. 580
● Vehicles with AUTO ACCESS SEAT: If the AUTO ACCESS SEAT has not
been locked in place after being stowed, the shift lever cannot be shifted
from P.
For details, refer to “AUTO ACCESS SEAT OWNER’S MANUAL”.

■Cruise control can be set when
●The shift lever is in D or the range 4, 5 or 6 of S has been selected.
● Vehicle speed is above approximately 25 mph (40 km/h).
■ Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
● Even without canceling the cruise control, the set speed can be increased
by first accelerating the vehicle to the desired speed and then pushing the
lever down to set the new speed.
■ Automatic cruise co ntrol cancelation
Cruise control will stop maintaining the vehicle speed in any of the following
situations.
● Actual vehicle speed falls more than approximately 10 mph (16 km/h) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.
● Actual vehicle speed is below approximately 25 mph (40 km/h).
● VSC is activated.
■ Operation guide display (vehicles wi th a multi-information display [with
color display])
● When the cruise control switch is operated, a guidance display is shown on
the multi-information display for a few seconds as to how to operate the
cruise control switch or distance switch. ( P. 98)
● When selecting tab on the multi-information display: P. 9 3
■ If the warning message for the crui se control is shown on the multi-
information display
Press the “ON-OFF” button once to deactivate the system, and then press
the button again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels imme-
diately after being activated, there may be a malfunction in the cruise control
system. Have the vehicle inspected by your Toyota dealer.

Dynamic radar cruise control supple ments conventional cruise control
with a vehicle-to-vehicle distance control. In vehicle-to-vehicle dis-
tance control mode, the vehicle automatically accelerates or deceler-
ates in order to maintain a set fo llowing distance from vehicles ahead.
