LX570_OM_OM60L96U_(U) Selecting conventional const ant speed control mode
Constant speed control mode differs from vehicle-to-vehicle distance
control mode. When constant speed con trol mode is selected, your vehi-
cle will maintain a set speed regardle ss of whether or not there are other
vehicles in the lane ahead.
Press the “ON-OFF” button to activate the cruise control. Press the button again to de activate the cruise control.
Switch to constant sp eed control mode. (Push the lever forward and
hold for approximately one second.) Cruise control indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle dis-
tance control mode, push the lever forw ard again and hold for approximately
1 second.
After the desired speed has been set, it is not possible to return to vehicle-to-
vehicle distance control mode.
If the “ENGINE START STOP” switch is turned off and then turned to
IGNITION ON mode again, the vehicle will automatically return to vehicle-
to-vehicle distance control mode.

Dynamic radar cruise control can be set when ●
The shift lever is in “D” or range “4” or higher of “S” has been selected.●
Range “4” or higher has been selected by using the paddle shift. (vehicles with
paddle shift switches) ●
Vehicle speed is above approximately 30 mph (50 km/h).■
Accelerating after s etting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distan ce to the vehicle
ahead. ■
Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations: ●
Actual vehicle speed falls below approximately 25 mph (40 km/h). ●
VSC is activated. ●
The sensor cannot operate correctly because it is covered in some way. ●
The windshield wipers are operating at high speed (when the wiper switch is set
to the “AUTO” mode or high speed wiper operation position).●
When second star t mode is set.●
The switching operation continues for 5 seconds or more after the center dif-
ferential lock switch has been operated.
If vehicle-to-vehicle distance control driv ing is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.

Automatic cancelation of constant speed control
The cruise control will stop maintaining th e vehicle speed in the following situations:●
Actual vehicle speed is more than approximately 10 mph (16 km/h) below the
set vehicle speed.
At this time, the memorized set speed is not retained.●
Actual vehicle speed falls below approximately 25 mph (40 km/h). ●
VSC is activated. ●
The switching operation continues for 5 seconds or more after the center dif-
ferential lock switch has been operated.■
Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice and plas-
tic objects, cannot be detect ed by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■
Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or to
inform the driver of the need for caution while driving. (  P. 837)Grille cover

When driving
LX570_OM_OM60L96U_(U) CAUTION■
Before using dynamic radar cruise control
Do not overly rely on vehicl e-to-vehicle distance control.
Be aware of the set speed. If automatic deceleration/acceleration is not appropri-
ate, adjust the vehicle speed, as well as the distance between your vehicle and vehi-
cles ahead by applying the brakes, etc. ■
Cautions regarding the driving assist systems
Observe the following precautions.
Failure to do so may cause an accident resulting in death or serious injury.●
Assisting the driver to measure following distance
The dynamic radar cruise control is only in tended to help the driver in determin-
ing the following distance between the driver’s own vehicle and a designated
vehicle traveling ahead. It is not a mech anism that allows careless or inattentive
driving, and it is not a system that can assist the driver in low-visibility conditions. It
is still necessary for driver to pay close attention to the vehicle’s surroundings. ●
Assisting the driver to judg e proper following distance
The dynamic radar cruise control dete rmines whether the following distance
between the driver’s own vehicle and a designated vehicle traveling ahead is
appropriate or not. It is not capable of making any other type of judgement.
Therefore, it is absolutely necessary for the driver to remain vigilant and to deter-
mine whether or not there is a possibi lity of danger in any given situation.●
Assisting the driver to operate the vehicle
The dynamic radar cruise control has no capability to prevent or avoid a collision
with a vehicle traveling ahead. Therefore, if there is ever any danger, the driver
must take immediate and direct control of the vehicle and act appropriately in
order to ensure the safety of all involved.■
To avoid inadvertent cruise control activation
Switch the cruise contro l off using the “ON-OFF” button when not in use.

Situations unsuitable for dy namic radar cruise control
Do not use dynamic radar cruise contro l in any of the following situations.
Doing so may result in inappropriate sp eed control and could cause an accident
resulting in death or serious injury. ●
In heavy traffic ●
On roads with sharp bends ●
On winding roads ●
On slippery roads, such as thos e covered with rain, ice or snow●
On steep downhills, or where there are sudden changes between sharp up and
down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.●
At entrances to expressways ●
When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, sn ow, sandstorm, heavy rain etc.)●
When an approach warning buzzer is heard often ●
When your vehicle is towing a trailer or during emergency towing

Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function correctly and could result in an accident. ●
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or damage
them. ●
Do not subject the sensor or surro unding area to a strong impact.
If the sensor moves even slightly off po sition, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by your Lexus dealer. ●
Do not disassemble the sensor. ●
Do not attach accessories or stickers to the sensor, grille cover or surrounding
area. ●
Do not modify or paint the sensor and grille cover. ●
Do not replace them with non-genuine parts.

Advice for driving on slippery roads ●
If you shift the four-wheel drive control switch to “L4” and the shift lever to the
“2” range of “S” or “D” (vehicles with paddle shift switches) while driving in
steep off-road areas, the output of the brake can be controlled effectively by the
Active TRAC, which assists the driver to control the driving power of 4 wheels. ●
Use the “1” range of “S” or “D” (vehicles with paddle shift switches) of the shift
lever for maximum power and traction wh en your wheels get stuck or when
driving down a steep incline.■
The center differential lock indicator light
The indicator light blinks while lock ing/unlocking the center differential.■
The center differential lock/unlock switch can be operated when ●
The “ENGINE START STOP” switch is in IGNITION ON mode.●
The vehicle speed is less than 60 mph (100 km/h).■
Locking/unlocking the center differential ●
When the four-wheel drive control switch is in L4 with the center differential
locked, VSC is automatically turned off. (The center differential lock and VSC
OFF indicator lights come on.) ●
If the operation is not completed, the center differential lock indicator blinks. If
the indicator light does not turn off when unlocking the center differential, drive
straight ahead while accelerating or decelerating, or drive in reverse. ●
If the center differential lock/unlock is not completed within 5 seconds while
the cruise control system is on, cancel the cruise control system.

When driving
LX570_OM_OM60L96U_(U) CAUTION■
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 weight distributing hitch
with sufficient capacity is required. ●
Adjust the tongue weight within the ap propriate 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 low-
est. Slow down sufficiently before making a turn, in crosswinds, on wet or slippery
surface, etc. to help avoid an accident. If you experience a vehicle-trailer instabil-
ity from reducing a certain speed, slow down and make sure you keep your vehi-
cle speed under the speed of whic h 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 surfaces. ●
Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue weight capacities. ●
Do not use cruise co ntrol when towing.●
Slow down and downshift before descendi ng 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 down hills. Before descend-
ing steep or long downhill grades, slow down and downshift. Do not make sud-
den 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 re sult in reduced braking efficiency.
