Trip information■ Driving range
■ Average fuel consumption after refueling
■ Current fuel consumption
■ Average vehicle speed Displays the estimated maximum distance that can
be driven with the quantity of fuel remaining.
This distance is computed based on your average fuel
consumption. As a result, the actual distance that can be
driven may differ from that displayed.
Displays the average fuel
consumption since the
vehicle was last refueled.
Displays the current rate of fuel consumption.
Displays the average vehicle speed since the engine
was started or the function was reset.
The function can be reset by pushing the “DISP” switch
for longer than 1 second when the average vehicle
speed is displayed.

■Barometer
■ Altimeter
■ Current fuel consumption
Displays the atmospheric pressure in the vehicle.
The displayed atmospheric pressure ranges from 17.8
IN.HG (600 hPa) up to 31.0 IN.HG (1050 hPa).
Displays the approximate altitude.
The displayed altitude ranges from -1500 ft. (-500 m)
up to 13000 ft. (4000 m).
Displays the elapsed time after the engine starts.
When the engine is started, driving time is counted
from 0:00.
Up to 19:59 (19 hours, 59 minutes) can be displayed.
■Altimeter mode
The indicated altitude of a single position may deviate according to the atmospheric
pressure and temperature.
While the altitude mode is displayed, push the “ ▲” or “▼ ” button to increase/
decrease the altitude by 50 ft. (or 10 m).
To reset the adjusted altitude, push and hold the “RESET” button for more than 1
second.
CAUTION

■Daytime running light system
To make your vehicle more visible to other drivers, the front turn signal lights turn on
automatically whenever the engine is started and the parking brake is released.
■Headlight control sensor
■Automatic light off system
The headlights and tail lights turn off 30 seconds after a door is opened or closed if
the ignition switch is turned to the “ACC ” or “LOCK” position while the headlights
are turned on. (The lights turn off immedi ately if the “LOCK” button on the key is
pressed after all doors are locked.)
To turn the lights on again, turn the igniti on switch to the “ON” position, or turn the
light switch “OFF” once and th en back to the or position.
■Customization
Settings (e.g. light sensor sensitivity) can be changed. ( P. 400)
NOTICE
■To prevent battery discharge
Do not leave the lights on longer than necessary when the engine is not running.
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.

Height control indicator lightsIf you change the vehicle height mode, the indicator lights change as fol-
lows: • The current mode indicator light w ill turn off, and the selected mode
indicator light will begin flashing.
• Once the change in vehicle height is complete, the selected mode indicator light will change from flashing to continuously lit.
■Operating conditions
●The engine must be running.
●Vehicle speed must be within the acce ptable range for the selected mode.
■Automatic change in vehicle height
If the vehicle speed exceeds 19 mph (30 km/h) when in the high mode, or 7 mph
(12 km/h) when in the low mode, norm al mode is automatically selected.
■Turning off the rear height control air suspension
●The system will remain off until the switch is pushed again, even if the ignition is
turned off.
●Even if the rear height control air suspen sion is turned off, the system automati-
cally selects the normal mode if the vehicle’s speed exceeds 19 mph (30 km/h).
■Automatic leveling function
The vehicle is adjusted to a fixed height for each mode, regardless of the number of
occupants and the luggage load.

■If the vehicle height does not change
If the area around the rear suspension is coated with ice, or the undercarriage has
come into contact with the road surface, the rear height control suspension will not
operate. In this case, the indicator lights will change as follows:
●The current mode indicator light will turn off, and the target mode indicator light
will begin flashing.
●The target mode indicator light will turn off, and the original mode indicator light
will be lit once more. (The vehicle height does not change.)
If the rear height control air suspension cannot be operated even after removing
the ice or progressing to a smooth driving surface, turn off and restart the engine.
■ Parking and stopping tips
●If you immediately stop the engine after of f-road driving, or park the vehicle for
a long time, the vehicle height may gradually lower. When parking, make sure
there is nothing under the vehicle that may come in contact with the underbody.
The vehicle will return to the set height when the engine is started.
●The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.
■When lowering the vehicle
Even if the engine is stopped while the ve hicle height is being lowered, operation
will continue for up to 25 seconds. If any of the side doors or the back door is
opened within this 25 seconds, operatio n will continue for a further 15 seconds.
■ Rear height control failure warning
●If a malfunction occurs in the rear height control air suspension, normal mode is
automatically selected.
The height control “OFF” indicator will blink, and the vehicle height control can-
not be activated until the malfunction is corrected. Have the vehicle checked at
your Lexus dealer as soon as possible.
●If the height control “OFF” indicator li ght does not come on when the ignition
switch is turned to the “ON” position, there is a malfunction in the rear height
control air suspension. You can continue normal driving, however have the vehi-
cle checked by your Lexus dealer as soon as possible.

When driving
CAUTION
Failure to observe the following precautions may result in an accident.
■ Using the high mode
This modes should only be used for rough off-road conditions. Because the vehi-
cle’s center of gravity is higher when in the high mode, the vehicle may become
unstable when turning abruptly.
■When jacking up the vehicle or installing tire chains
Turn off the rear height control air suspension and stop the engine, otherwise the
vehicle height may change due to the automatic leveling function.
■ When driving through water deeper than 2.3 ft. (0.7 m)
Select the “HI” (high) mode and turn off rear height control air suspension. Drive at
19 mph (30 km/h) or lower. Otherwise, the vehicle height may change due to the
automatic leveling function.
■If your vehicle must be towed
Put the vehicle height in the normal mode and turn off the rear height control air
suspension, otherwise the vehicle height may change due to the automatic leveling
function.
■If your vehicle becomes stuck in a ditch
Turn off the rear height control air susp ension, otherwise the vehicle height may
change due to the automatic leveling function.

NOTICE
■To avoid damage to the vehicle
●If in the low mode, the vehicle automatically shifts to the normal mode (vehicle
height is raised) when the engine is started. Take care when overhead height is
limited.
●After unloading, the vehicle height may be slightly higher than normal. Take care
when overhead height is limited.
●Before lowering the vehicle height, check that no-one is under the vehicle and
the area is free of obstructions. Also check that the underbody of the vehicle will
not touch the ground.
●Do not select the low mode when drivin g on bumpy roads, as the underbody of
the vehicle may contact the road surface.
■ Avoid rapid changes to the vehicle height when the vehicle is heavily loaded
As the compressor may overheat, causing the vehicle height adjustment operation
to stop.

wheels spin, the slip indicator light
flashes to indicate that the VSC/
TRAC/hill-start assist control sys-
tems have been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
The stop lights and high mounted
stoplight turn on when the hill-start
assist control system is operating.
The slip indicator light flashes as
well when ABS is operating.

control systems
●A sound may be heard from the engi ne compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
