Driving
the vehicle speed is approximately 20
mph (30 km/h) or more. (However, when
the vehicle speed is set while driving at
below approximately 20 mph [30 km/h],
the set speed will be set to approximately
20 mph [30 km/h].)
■Accelerating after setting the vehicle
speed
The vehicle can accelerate by operating the
accelerator pedal. After accelerating, the
set speed resumes. However, during vehi-
cle-to-vehicle distance control mode, the
vehicle speed may decrease below the set
speed in order to maintain the distance to
the preceding vehicle.
■When the vehicle stops while follow-up
cruising
●Pressing the +RES sw itch while the vehi-
cle ahead stops will resume follow-up
cruising if the vehicle ahead starts off
within approximately 3 seconds after the
switch is pressed.
●If the vehicle ahead starts off within 3 sec-
onds after your vehicle stops, follow-up
cruising will be resumed.
■Automatic cancelation of vehicle-to-
vehicle distance control mode
Vehicle-to-vehicle dist ance control mode is
automatically canceled in the following situ-
ations.
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is
turned off.
●The sensor cannot detect correctly
because it is covered in some way.
●Pre-collision braking is activated.
●The parking brake is operated.
●The vehicle is stopped by system control
on a steep incline.
●The following are detected when the
vehicle has been stopped by system con-
trol:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes If vehicle-to-vehicle
distance control mode
is automatically canceled for any reasons
other than the above, there may be a mal-
function in the system. Contact your Lexus
dealer.
■Automatic cancelation of constant
speed control mode
Constant speed control mode is automati-
cally canceled in the following situations:
●Actual vehicle speed is more than
approximately 10 mph (16 km/h) below
the set vehicle speed.
●Actual vehicle speed falls below approxi-
mately 20 mph (30 km/h).
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is
turned off.
●Pre-collision braking is activated.
If constant speed control mode is automati-
cally canceled for any reasons other than
the above, there may be a malfunction in the
system. Contact your Lexus dealer.
■Brake operation
A brake operation sound may be heard and
the brake pedal response may change, but
these are not malfunctions.
■Warning messages and buzzers for
dynamic radar cruise control with full-
speed range
Warning messages and buzzers are used to
indicate a system malfunction or to inform
the driver of the need for caution while driv-
ing. If a warning messa ge is shown on the
multi-information displa y, read the message
and follow the instructions. ( P.167, 368)
■When the sensor may not be correctly
detecting the vehicle ahead
In the case of the fo llowing and depending
on the conditions, operate the brake pedal
when deceleration of the system is insuffi-
cient or operate the accelerator pedal
when acceleration is required.
As the sensor may not be able to correctly
detect these types of vehicles, the approach
warning ( P.193) may not be activated.
●Vehicles that cut in suddenly

When not in SPORT mode, if the Driving
Mode Select switch is turned away from
you, the “Sport” indicator comes on.
■Operation of the air conditioning sys-
tem in Eco drive mode
Eco drive mode controls the heating/cool-
ing operations and fan speed of the air con-
ditioning system to enhance fuel efficiency.
To improve air condit ioning performance,
perform the following operations:
●Turn off eco air conditioning mode
(  P.257)
●Adjust the fan speed ( P.256)
●Turn off Eco drive mode ( P.202)
■Auto Glide Control
●While driving in Eco drive mode with D
position, selected, releasing the accelera-
tor pedal will activate Auto Glide Control
under certain conditions. (Auto Glide
Control may activate before the acceler-
ator pedal is fully released.)
When Auto Glide Control operates, the
electric motor (traction motor) will be
controlled, reducing the deceleration
force and allowing the vehicle to coast,
enhancing fuel economy.
When Auto Glide Control operates, the
AGC indicator light will illuminate.
●Auto Glide Control may not operate in
the following situations:
• When not in Eco drive mode
• When the brake pedal is depressed
• When a shift position other than D is selected
• When the vehicle speed is approximately 10 mph (15 km/h) or lower
• When the vehicle is accelerating on a downward slope
• When the PCS (Pre-Collision System) is operating
• When the dynamic radar cruise control with full-speed range is operating
• When the PKSB (Parking Support Brake) system is operating
• When the TRAC or VSC system is oper-
ating
• When the TRAC or VSC system is dis-
abled by pressing the switch
■Automatic deactivation of sport mode
If the power switch is turned off after driving
in sport mode, the drive mode will be
changed to normal mode.
■Driving mode pop-up display (12.3-inch
display model)
When the driving mode is changed, the
selected driving mode will be temporarily
displayed on the side display. ( P.249)

WARNING
●Do not use more than one compact
spare tire simultaneously.
●Replace the compact spare tire with a
standard tire as soon as possible.
●Avoid sudden acceleration, abrupt
steering, sudden braking and shifting
operations that cause sudden engine
braking.
■When the compact spare tire is
attached
The vehicle speed may not be correctly
detected, and the following systems may
not operate correctly:
• ABS & Brake assist
• VSC
• TRAC
• Dynamic radar cruise control with full- speed range
• PCS (Pre-Collision System)
• EPS
• LTA (Lane Tracing Assist)
• Panoramic view monitor (if equipped)
• Lexus parking assist monitor (if equipped)
• Intuitive parking assist (if equipped)
• Navigation system (if equipped)
• BSM (Blind spot monitor) (if equipped)
• Automatic high Beam
■Speed limit when using the compact
spare tire
Do not drive at speeds in excess of 50
mph (80 km/h) when a compact spare
tire is installed on the vehicle.
The compact spare tire is not designed
for driving at high speeds. Failure to
observe this precaution may lead to an
accident causing deat h or serious injury.
■After using the tools and jack
