1-7. Safety information
CAUTION
nFront passenger occupant classification system precautions
lDo not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear seat, return the seatback to a position where it does
not touch the rear seat. Keep the front passenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
lIf an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator still remains illuminated, either ask the pas-
senger to move to the rear seat, or if that is not possible, move the front passenger
seat fully rearward.
lWhen it is unavoidable to install the forward-facing child restraint system on the
front passenger seat, install the child restraint system on the front passenger seat
in the proper order. (→P. 1 3 1 )
lDo not modify or remove the front seats.
lDo not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction of the detection sys-
tem. In this case, contact your Lexus dealer immediately.
lChild restraint systems installed on the rear seat should not contact the front seat-
backs.
lDo not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
lDo not modify or replace the upholstery of the front seat.

2-1. Driving procedures
nSnow mode automatic deactivation
Snow mode is automatically deactivated if the “ENGINE START STOP” switch is
turned off after driving in snow mode.
nS mode
lWhen the shift range is “5” or lower, holding the shift lever toward “+” sets the
shift range to “6”.
lTo prevent the engine from over-revving, upshifting may automatically occur.
lTo protect the automatic transmission, a function is adopted that automatically
selects a higher shift range when the fluid temperature is high.
nAI-SHIFT
AI-SHIFT automatically selects the optimal gear according to driver performance
and driving conditions.
AI-SHIFT automatically operates when the shift lever is in the D position. (Shifting
the shift lever to the S position cancels the function.)
nWhen driving with the cruise control or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to “5” or “4”.
(→P. 204, 208)
nIf the shift lever cannot be shifted from P
→P. 5 7 9
nIf S does not come on even after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have the
vehicle inspected by your Lexus dealer immediately.
(In this situation, the transmission will operate in the same as manner as when the
shift lever is in D.)
nDownshift restriction warning buzzer (S mode)
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 is operated. (The buzzer will sound twice.)

CAUTION
nIf 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 your Lexus dealer immediately if this occurs.
nWarning lights
Warning lights inform the driver of malfunctions in any of the vehi-
cle’s systems. (→P. 535)
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the engine is started, or after a few sec-
onds. 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 your Lexus
dealer, for details.

2-4. Using other driving systems
Driving in vehicle-to-vehicle distance control mode
This mode employs a sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead and to judge the distance between
your vehicle and the vehicle ahead of you.
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 in the same lane, the system
automatically 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
2

When driving
Example 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 dis-
tance set by the driver.
Example of acceleration
When there no longer are vehicles driving slower than the set speed in
the lane ahead
When the vehicle ahead of you executes a lane change, the system slowly
accelerates until the set speed is reached. The system then returns to con-
stant speed cruising.
Approach warning
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 a 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.
nDynamic radar cruise can be set when
lThe shift lever is in D. (Recommended)
Dynamic radar cruise control can also be set when the shift lever is in the S posi-
tion and range “4”, “5”, or “6” has been selected.
lVehicle speed is above approximately 30 mph (50 km/h).
nSwitching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle
distance control mode has been used. The mode also cannot be switched from
constant speed control to vehicle-to-vehicle distance control mode. Turn the sys-
tem off by pressing the “ON-OFF” button, and turn it on again.
nAccelerating
The vehicle can accelerate normally. After acceleration, the set speed resumes.
