2-1. Driving procedures
RX350/270_EE
■When driving with cruise control or radar cruise control activated
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.

CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag 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 immediately if this occurs.

■Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following situa-
tions:
●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 40 km/h (25 mph).
●VSC is activated.
●VSC+ is activated (if equipped).
■If a warning message is shown on the multi-information display
Press the “ON-OFF” button once to deactivate the system, and then press the but-
ton again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately
after being activated, there may be a malfunction in the cruise control system. Have
the vehicle inspected by any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
CAUTION
■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

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.
