nIf 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 vehicle will operate as if the shift lever is in D.)
nAI-SHIFT
The AI-SHIFT automatically shifts the gear to the optimal position according to the
driver performance and driving conditions.
The AI-SHIFT automatically operates when the shift lever is in the D position. How-
ever, operating the “-” shift paddle switch will restrict the function’s operation. (Shift-
ing the shift lever to the S position cancels the function.)
CAUTION
nWhen driving on slippery road surfaces
Be careful of downshifting and sudden acceleration, as this could result in the vehi-
cle skidding to the side or spinning.

nGear position display
(vehicles with an automatic transmission only)
Indicates the current gear, and the range of gears
that is available when the shift lever is in the D or S
position. the gear range is shown by the number of
dots (•) and the current gear is shown as a number.
The transmission automatically selects the gears
within the driver selected gear range.
In the illustration to the left, a range of 6 available gears
(1 through 6) has been selected by the driver. (The shift
lever is in the D or S position with 6 ranges enabled) It is
possible for the transmission to automatically select
between all 6 of the gears. In this case, the transmission
has selected third gear.
nSystem check display
After switching the “ENGINE START STOP” switch to IGNITION ON mode,
“CHECK” is displayed while system operation is checked. When the system check
is complete, “COMPLETED” is displayed before returning to the normal screen.
nOutside temperature display
In the following situations, the correct outside temperature may not be displayed, or
the display may take longer than normal to change.
lWhen stopped, or driving at low speeds (less than 12 mph [20 km/h])
lWhen the outside temperature has changed suddenly (at the entrance/exit of a
garage, tunnel, etc.)

[1.6 km/h]) can be made by
lightly pressing the lever up or
down and releasing it.
nCanceling and resuming regular acceleration

2-4. Using other driving systems
nCruise control can be set when
lVehicles with an automatic transmission: the shift lever is in the D position or S
position. However, it cannot be set if any of the ranges 1 through 3 has been
selected.
lVehicle speed is between approximately 25 mph (40 km/h) and 125 mph
(200 km/h).
nAccelerating
The vehicle can be accelerated normally.
nAutomatic cruise control cancellation
The set speed is automatically cancelled in any of the following situations.
lActual vehicle speed falls more than 10 mph (16 km/h) below the preset vehicle
speed
At this time, the memorized set speed is not retained.
lActual vehicle speed is below 25 mph (40km/h)
lVSC is activated
nIf the cruise control indicator light flashes
Turn the “ON-OFF” button off once, and then 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 your Lexus dealer.

2-4. Using other driving systems
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.
nABS (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.
nBrake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
nVSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces.
nTRAC (Traction Control)
Maintains drive power and prevents the rear wheels (2WD models) or all
wheels (AWD models) from spinning when starting the vehicle or acceler-
ating on slippery roads.
nHill-start assist control (vehicles with an automatic transmission)
Prevents the vehicle from rolling backwards when starting on an incline or
slippery slope.
nEPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel.
