■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 acci-
dent resulting in death or serious injury. Vehicle stability and braking performance are
affected by trailer stability, brake setting and performance, and the hitch. Your vehicle
will handle differently when towing a trailer.
■To avoid accident or injury
●Do not exceed the TWR, unbrak ed TWR, GCWR, GVWR or GAWR.
●Adjust the tongue weight within the approp riate range. Place heavier 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 cr oss winds, on wet or slippery surface, etc.
to help avoid an accident. If you experience a vehicle-trailer instability from reducing
a certain speed, slow down and make sure you keep your vehicle speed under the
speed of which you expe rience the instability.
●Do not make jerky, abrupt or sharp turns.
●Do not apply the brakes suddenly as you may skid, resulting in ja ckknifing and loss of
vehicle control. This is especially true on wet or slippery surfaces.
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities.
●Do not use the following systems when trailer towing.
• Cruise control (if equipped)
• Dynamic radar cruise control (if equipped)
• Dynamic cruise control with full-speed range (if equipped)
●Slow down and downshift before descending steep or long downhill grades. Do not
make sudden downshifts while descen ding 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 down-
shifts when descending stee p 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 a compact spare tire: Do no t 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 manu-
facturer. Even though the vehicle may be physically capable of towing a higher weight,
the operator must determine the maximum weig ht rating of the particular hitch assem-
bly 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.

■S mode
●When the shift range is 4 or lower, holding th e shift lever toward “+” sets the shift range
to 6.
●Automatically selects a higher shift range before the engine speed becomes too high.
■Downshifting restriction warning buzzer
To help ensure safety and driving performa nce, 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 cruise control (if equipped), dynamic radar cruise control (if
equipped) or dynamic radar cruise control with full-speed range (if equipped) acti-
vated
Even when performing the following actions with the intent of enabling engine braking,
engine braking will not activate because cruise control, dynamic radar cruise control or
dynamic radar cruise control with full-speed range will not be canceled.
●While driving in S mode, downshifting to 5 or 4. ( P. 2 0 9 )
●When switching the driving mode to sp ort mode while driving in D position.
(  P. 303)
■Restraining sudden start (Drive-Start Control)
When the following unusual operation is pe rformed, the hybrid system output may be
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 wa rning message appears on the multi-infor-
mation display. If a warning message is show n on the multi-information display, read the
message and follow the instructions.
●When the accelerator pedal is depresse d too while the vehicle is in reverse.

Dynamic radar cruise control
Without accelerator pedal operation by the driver, in vehicle-to-vehicle distance
control mode, the vehicle automatically accelerates and decelerates in accor-
dance to the changes in speed of the pr eceding vehicle. In constant speed con-
trol mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control on freeways and highways.
●Vehicle-to-vehicle distance control mode ( P. 2 4 1 )
●Constant speed control mode ( P. 2 4 6 )

Pulling the lever toward you cancels
the speed control.
The speed setting is also canceled when
the brake pedal is depressed.
Pushing the lever up resumes the
speed control and returns vehicle
speed to the set speed.
However, resuming is available when the vehicle speed is more than approximately
25 mph (40 km/h).
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehicle-
to-vehicle distance.
■Warnings may not occur when
In the following instances, there is a possibility that the warnings will not occur:
●When the speed of the preceding vehicle matches or exceeds your vehicle
speed
●When the preceding vehicle is traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●When depressing the accelerator pedal

●The shift lever is in D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the
set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle.
■Automatic cancelation of vehicle- to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
●The sensor cannot detect properly beca use it is obstructed in some way.
●Pre-collision braking is activated.

ing situations, “Radar Cruise Control Unavaila ble” will be displayed on the multi-infor-
mation display:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●The windshield wipers are oper ating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
If vehicle-to-vehicle distance control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control mode
Constant speed control mode is automatica lly canceled in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
