About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
• When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less than that of other
vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.
When driving with cruise control or dynamic radar cruise control activated
Even if switching the driving mode to sport mode with the intent of enabling
engine braking, engine braking will not activate because cruise control or
dynamic radar cruise control will not be canceled.
Automatically P position selection function
When the shift position is in a position other than P, pressing the power switch
with the vehicle stopped completely will cause the shift position to change to P
automatically, and then the power switch will turn off.
If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (P. 623)
After recharging/reconnecting the 12-volt battery
P. 507
Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features: P. 650)

Cruise control can be set when
The shift position is in D.
Vehicle speed is above approximately 40 km/h (25 mph).
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 control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following sit-
uations.
Actual vehicle speed falls more than approximately 16 km/h (10 mph) below
the preset vehicle speed.
At this time, the memorized set speed is not retained.
Actual vehicle speed is below approximately 40km/h (25 mph).
VSC is activated.
If the warning message for the cruise 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 immedi-
ately after being activated, there may be a malfunction in the cruise control sys-
tem. Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.

To avoid operating the cruise control by mistake
Switch the cruise control off using the “ON-OFF” button when not in use.
Situations unsuitable for cruise control
Do not use cruise control in any of the following situations.
Doing so may result in loss of 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 those covered with rain, ice or snow
On steep hills
Vehicle speed may exceed the set speed when driving down a steep hill.
During emergency towing

Dynamic radar cruise control
Dynamic radar cruise control supplements conventional cruise control
with a vehicle-to-vehicle distance control. In vehicle-to-vehicle distance
control mode, the vehicle automatically accelerates or decelerates in
order to maintain a set following distance from vehicles ahead.

Pulling the lever toward you can-
cels the cruise control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
Resuming is available when the
vehicle speed is more than approxi-
mately 40 km/h (25 mph).
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 120 m (400 ft.) ahead, determines the current vehicle-to-
vehicle following distance, and operates to maintain a suitable following
distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.

When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic 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. Apply the brakes to ensure an appropriate vehicle-to-vehicle dis-
tance.
Warnings may not occur when
In the following instances, there is a possibility that the warnings will
not occur:
When the speed of the vehicle ahead matches or exceeds your vehi-
cle speed
When the vehicle ahead is traveling at an extremely slow speed
Immediately after the cruise control speed was set
At the instant the accelerator is applied

Constant speed control mode differs from vehicle-to-vehicle distance
control mode. When constant speed control mode is selected, your vehi-
cle will maintain a set speed regardless 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 deactivate
the cruise control.
Switch to constant speed 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 distance
control mode, push the lever forward again and hold for approximately 1 sec-
ond.
After the desired speed has been set, it is not possible to return to vehicle-to-
vehicle distance control mode.
If the power switch is turned off and then turned to ON mode again, the vehi-
cle will automatically return to vehicle-to-vehicle distance control mode.

Dynamic radar cruise control can be set when
The shift position is in D.
Vehicle speed is above approximately 50 km/h (30 mph).
Accelerating after setting 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 distance to the vehicle
ahead.
Set speed
The set speed may be unsustainable depending on driving circumstances.
