Driving
■Driving on a downhill
On declines, there may be case where the vehicle shifts down automatically to obtain
engine braking. As a result of the down shifting, the engine speed may increase.
■Second start mode automatic deactivation
Second start mode is automatically deactivated if the engine is turned off after driving in
second start mode.
■S mode
When the shift range is 5 or lower, holding the shift lever toward “+” sets the shift range to
6.
■AI-SHIFT
AI-SHIFT automatically shifts the gear to the suitable position according to driver perfor-
mance 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.)
■When driving with the cruise contro l or dynamic radar cruise control
Engine braking will not occur in S mode, even when downshifting to 5 or 4.
( P. 229, 232)
■Shift lock system
The shift lock system is a system to prevent ac cidental operation of the shift lever in start-
ing.
The shift lever can be shifted from P only when the engine switch is in the IGNITION ON
mode and the brake pedal is being depressed.

■Daytime running light system
●The daytime running lights illuminate using th
e same lights as the parking lights and illu-
minate brighter than the parking lights.
●To make your vehicle more visible to other drivers during daytime driving, the daytime
running lights turn on automatically when a ll of the following conditions are met. (The
daytime running lights are not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the (type B only), or “AUTO”* position
*: When the surroundings are bright
The daytime running lights rema in on after they illuminate even if the parking brake is
set again.
●For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●Compared to turning on the headlights, the daytime running light system offers greater
durability and consumes less electricity, so it can help improve fuel economy.
■Headlight control sensor
■Automatic light off system
●When only the tail lights are on: All lights turn off if the engine switch is turned to
ACCESSORY mode or turned off and the driver’s door is opened.
●When the headlights are on: A ll lights turn off 30 seconds after a door or the glass
hatch is opened and closed.
To turn the lights on again, turn the engine switch to IGNITION ON mode, or turn the
light switch once and then back to or . The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

Constant speed control mode differs from vehicle-to-vehicle distance control
mode. When constant speed control mode is selected, your vehicle will maintain
a set speed regardless of whether or no t there are other vehicles in the lane
ahead.
Press the “ON-OFF” button to acti-
vate the cruise control.
Press the button again to deactivate the
cruise control.
Switch to constant speed control
mode. (Push the lever forward and
hold for approximately 1 second.)
Constant speed control mode indicator
will come on.
When in constant speed control mode, to re turn to vehicle-to-vehicle distance con-
trol mode, push the lever forward agai n and hold for approximately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-to-vehicle
distance control mode.
If the engine switch is turned off and then turned to IGNITION ON mode again, the
vehicle will automatically return to vehi cle-to-vehicle distance control mode.

■Dynamic radar cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Switching modes
The mode cannot be switched to constant sp
eed control mode if vehicle-to-vehicle dis-
tance control mode has been used. The mode also cannot be switched from constant
speed control to vehicle-to-vehicle distance control mode. Turn the system off by press-
ing the “ON-OFF” button, and turn it on again.
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes. How-
ever, during vehicle-to-vehicle distance control mode, the vehicle speed may decrease
below the set speed in order to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following situ-
ations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are operating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
●When second start mode is set.
●Bad weather causes the detection function to become extremely unstable.
●Multi-terrain mode is selected other than OFF.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
If vehicle-to-vehicle distance control drivin g is automatically canceled for any other rea-
son, there may be a malfunction in th e system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
●Actual vehicle speed is more than approxim ately 10 mph (16 km/h) below the set vehi-
cle speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.

CAUTION
■The rear height control air suspension must be turned off
Be sure to observe the following precautions. Otherwise, the automatic leveling func-
tion may cause vehicle height to change, an
d you may catch part of your body in the
vehicle, resulting in an accident:
●When jacking up the vehicle, installing tire chains or tying the vehicle with chains/
wires for transportation via flatbed truck, tu rn off the rear height control air suspen-
sion and stop the engine.
●When the vehicle must be towed or disconnect ing a trailer, put the vehicle height in N
mode and turn off the rear he ight control air suspension.
●When the vehicle is stuck, turn off the rear height control air suspension.
■Selecting the correct height mode
●HI mode should only be used when drivin g on rough roads, for example when driving
off-road.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Do not select HI mode when loading cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Before lowering vehicle height, check that there is no one under the vehicle.
NOTICE
■Be careful in any place where overhead space is limited
The vehicle height will rise when a higher mode is selected or cargo is unloaded. This
may cause damage to the vehicle.
■Do not select LO mode when driving on bumpy roads
If the underbody of the vehicle touches a rugged road surface, the vehicle may be
damaged.
■Changing vehicle height
Do not change vehicle height frequently.
The compressor may overhe at and stop operation.
■When on the extremely uneven roads with rocks
Sometimes the vehicle height is not adjusted because it is judged as uneven road driv-
ing.
