Even when performing the following actions with the intent of enabling engine
braking, engine braking will not activate while driving in S mode and downshifting
to 5 or 4 because cruise control or radar cruise control will not be canceled.
(→P. 230, 234)
■If the shift lever cannot be shifted from P
→P. 5 8 9
■If S does not come on or D comes on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the
vehicle inspected by any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional immediately.
(In this situation, the transmission will operate in the same as manner as when the
shift lever is in D.)
■Downshift restriction warning buzzer
To help ensure safety and driving performance, downshifting operation may some-
times be restricted. In some circumstances, downshifting may not be possible even
when the shift lever or paddle shift switch is operated. (The warning buzzer will
sound twice.)
CAUTION
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid, resulting in
an accident.

injury. Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional immediately if this occurs.

2-4. Using other driving systems
RX350/270_EE
Driving in vehicle-to-vehicle distance control mode
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 follow-
ing 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-vehi-
cle distance can also be set by operating the vehicle-to-vehicle distance con-
trol.
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 automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, 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.
