When the “-” shift paddle switch is operated in the D position
When the “-” shift paddle switch is operated in the D position, a shift range
will be automatically selected. The highest gear of the first shift range will
be one gear lower than the gear in use during normal D position driving.
Automatic deactivation of shift range selection in the D position
Shift range selection in the D position will be deactivated in the following
situations:
When the vehicle comes to a stop
When range 6 is selected and the accelerator pedal is depressed
If the accelerator pedal is depressed for more than a certain period of
time
To protect automatic transmission
A function is adopted that automatically selects a higher shift range when
the fluid temperature is high.
Gear range display when driving
The current gear is displayed on the multi-information display. (P. 184)
Downshifting restrictions warning buzzer
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 or shift paddle switch is operated. (The
warning buzzer will sound twice.)
When driving with the cruise control system or dynamic radar cruise control
system
Engine braking will not occur during shift range selection in the D position
or S mode, even when downshifting to range 5 or 4. (P. 198, 202)
Snow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP”
switch is turned off after driving in snow mode.
If the shift lever cannot be shifted from P

CAUTION
If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not
come on when you start the engine, this could mean that these systems are
not available to help protect you in an accident, which could result in death
or serious injury. Have the vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional, immedi-
ately if this occurs.
Warning lights
Warning lights inform the driver of malfunctions in any of the
vehicle’s systems. (P. 467)
*:These lights turn on when the “ENGINE START STOP” switch is
turned to IGNITION ON mode to indicate that a system check is
being performed. They will turn off after the engine is started, or
after a few seconds. There may be a malfunction in a system if a
light does not come on, or if the lights do not turn off. Have the
vehicle inspected by any authorized Lexus dealer or repairer, or

When driving
IS250/220d/200d_EE
Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehi-
cles up to approximately 120 m (400 ft.) ahead, determines the cur-
rent 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.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-
to-vehicle distance can also be set by operating the vehicle-to-vehicle
distance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automat-
ically decelerates your vehicle. When a greater reduction in vehicle
speed is necessary, the system applies the brakes. A warning tone
warns you when the system cannot decelerate sufficiently to prevent
your vehicle from closing in on the vehicle ahead.

2-4. Using other driving systems
IS250/220d/200d_EEExample of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes
in the speed of the vehicle ahead in order to maintain the vehicle-to-
vehicle distance set by the driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than
the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.
Approach warning
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. Apply the brakes to ensure an
appropriate vehicle-to-vehicle distance.
Warnings may not occur when
In the following instances, there is a possibility that the warn-
ings will not occur:
When the speed of the vehicle ahead matches or exceeds your
vehicle 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

Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following
situations:
Actual vehicle speed is more than approximately 16 km/h (10 mph)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
Actual vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
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 plastic objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
Warning lights, messages and buzzers for dynamic radar cruise control
Warning lights, messages and buzzers are used to indicate a system mal-
function or to inform the driver of the need for caution while driving. (P.
