When driving
IS F_U
■Starting off on a hill
Hill-start assist control will operate. (→P. 2 0 1 )
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the windows
may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially
slippery.
●Refrain from high speeds when driving on an expressway in the rain, because
there may be a layer of water between the tires and the road surface, preventing
the steering and brakes from operating properly.
■Engine speed while driving
In the following conditions, the engine speed may become high while driving. This is
due to automatic up-shifting control or down-shifting implementation to meet driv-
ing conditions. It does not indicate sudden acceleration.
●The vehicle is judged to be driving uphill or downhill
●When the accelerator pedal is released
●With the F-sport mode total control swit ch activated, when the brake pedal is
depressed
■Breaking in your new Lexus
To extend the life of the vehicle, the following precautions are recommended to
observe:
●For the first 186 miles (300 km):
Avoid sudden stops.
●For the first 621 miles (1000 km):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in the low gears.
• Do not drive at a constant speed for extended periods.

■Rev indicator
■Downshift restrictions 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. (A buzzer will sound twice.)
■When driving with the cruise control or dynamic radar cruise control
Engine braking will not occur during shift range selection in the D position, even
when downshifting to range 7, 6, 5 or 4. (→P. 177, 181)
■Automatic deactivation of snow mode and “Sport” mode
If the “ENGINE START STOP” switch is turned OFF after driving in either snow
mode or “Sport” mode, the mode is automatically deactivated.
■If the shift lever cannot be shifted from P
→P. 5 0 3
●When the shift lever is in D (paddle shift
switches operated) or in M, an indicator on
the tachometer illuminates in 3 steps in the
case of high engine speeds to encourage
the driver to upshift.
●If the third (red) segment illuminates, a
buzzer will also sound.

■Indicators
The indicators inform the driver of the operating state of the vehi-
cle’s various systems.
*1: 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
your Lexus dealer.
*2: The light flashes to indicate that the system is operating.
*3: The light flashes when the system is turned off. The light flashes quicklyto indicate that the system is operating.

Driving assist systems
To help enhance driving safety and performance, the following systems
operate automatically in response to various driving situations. Be aware,
however, that these systems are supplementary and should not be relied
upon too heavily when operating the vehicle.
■ ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
■TRAC (Traction Control)
Helps to maintain drive power and prevent the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■Hill-start assist control
Helps to prevent the vehicle from rolling backwards when starting on an
incline or slippery slope.
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
■VDIM (Vehicle Dynamics Integrated Management)
Provides integrated control of the ABS, brake assist, TRAC, VSC, hill-start
assist control, and EPS systems.
Helps to maintain vehicle stability when swerving on slippery road sur-
faces by controlling the brakes, engine output and steering assist.
When the F-sport mode total control switch is pressed, “Sport” mode is
activated. ( →P. 2 0 3 )
■PCS (Pre-Collision System) (if equipped)
→ P. 2 0 7

Turning off TRAC and VSC
To turn the TRAC and VSC sys-
tems off, press and hold the switch
for 3 seconds or more while the
vehicle is stopped.
The “TRAC OFF” indicator light
and VSC off indicator light should
come on.
Push the switch again to turn the
system back on.
F-sport mode total control switch
Your vehicle is equipped with two types of control modes to accommo-
date various driving preferences. The control modes can be selected with
the F-sport mode total control switch. Normal mode allows secure and
smooth normal driving. When the switch is pressed, “Sport” mode is acti-
vated. Control characteristics such as the ECT, EPS, VSC and TRAC are
adjusted to afford maneuverability closer to what a driver may have imag-
ined, while a sense of security is retained. “Sport” mode/Normal mode
The “SPORT” indicator comes on
when in “Sport” mode.

■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.
■Automatic deactivation of “Sport” mode
When the “ENGINE START STOP” switch is turned off after driving in “Sport”
mode, the mode is automatically deactivated.
■If the slip indicator comes on
It may indicate a malfunction in the VSC, TRAC or hill-start assist control system.
Contact your Lexus dealer.
CAUTION
■The ABS does not operate effectively when
●The limits of tire gripping performance have been exceeded (such as excessively
worn tires on a snow covered road).
●The vehicle hydroplanes while driving at high speed on the wet or slick road.
■Stopping distance when the ABS is operating may exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always main-
tain a safe distance from the vehicle in front of you, especially in the following situa-
tions.
●When driving on dirt, gravel or snow-covered roads
●When driving over bumps in the road
●When driving over roads with potholes or roads with uneven roads
■TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slippery road
surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
