depressed.
■Avoiding damage to vehicle parts
●Do not turn the steering wheel fully in either direction and hold it there for a long
time.
Doing so may damage the power steering pump.
●When driving over bumps in the road, drive as slowly as possible to avoid damag-
ing the wheels, underside of the vehicle, etc.
■If you hear a squealing or scraping no ise (brake pad wear limit indicators)
Have your Lexus dealer check and replac e the brake pads as soon as possible.
The rotor damage can result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads and/or
that of the brake discs are exceeded.

Vehicle height modesPress “ ▲” to step up one height mode, and “▼ ” to step down one height
mode. (Ex. When in the lo w height mode, press “▲” once to switch to the
normal height mode, and twice to sw itch to the high height mode.)
■ “HI” (high) height mode
Vehicle height is 1.6 in. (40 mm) higher at the front, and 2.0 in. (50
mm) higher at the rear than the normal mode height.
This mode is suitable when driving on bumpy roads or through water.
High height mode is only available when the vehicle speed is under 19
mph (30 km/h).
■ “N” (normal) height mode
The standard vehicle height. This mode is suitable for ordinary driving.
■ “LO” (low) height mode
Vehicle height is 2.0 in. (50 mm) lower at the front, and 1.6 in. (40 mm)
lower at the rear than the normal mode height.
This mode allows easy access to the vehicle.
Low height mode is only availabl e when the vehicle is stopped. When
you start the vehicle, normal height mode is automatically selected.
Conditions for changing the vehicle height mode
Some modes may not be selectable depending on the vehicle speed
when the four-wheel drive control lev er is in the “H” position. Refer to the
following table.

2-4. Using other driving systems
AHC 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 fr om flashing to continuously lit.
If you press the height control switch while AHC is off, the current mode
indicator light will turn on and the selected mode indicator light will begin
flashing while the system starts up.
Once the system has star ted, the current mode indi cator light will turn off.
■Operating conditions
●The engine must be running.
●All side doors and the back door must be closed.
■Automatic change in vehicle height when in the high mode
●If the vehicle speed exceeds 19 mph (30 km/h) with the four-wheel drive con-
trol lever in the “H” position, normal mode is automatically selected.
●If the vehicle speed exceeds 30 mph (50 km/h) with the four-wheel drive con-
trol lever in the “L” position, the vehicle height is lowered to 1.0 in. (25 mm)
higher than the normal mode height. If the vehicle speed drops to 12 mph (20
km/h) or less, high mode is automatically resumed.

When driving
■Extra high mode
If the vehicle becomes stuck, extra high mode may be automatically selected when
the vehicle height is in high mode with the four-wheel drive control lever in the “L”
position.
The vehicle height is raised to 2.8 in. (70 mm) higher than the normal mode height,
or slightly higher.
Extra high mode will change back to high mode when:
• The vehicle is no longer stuck
• The four-wheel drive control lever is shifted to a position other than “L”
●If you push “ ▼” when in extra high mode, normal mode is selected.
●Extra high mode cannot be manually selected.
■Turning off the active height control suspension
●The system will remain off until the switch is pushed again, even if the ignition is
turned off.
●Even if AHC is turned off, the system automatically 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.
●However the vehicle cannot be raised if the vehicle load exceeds the following
limits:
• Up to 4 occupants* plus approximately 661 lb. (300 kg) in the normal mode
• Up to 4 occupants* plus approximatel y 375 lb. (170 kg) in the high mode
*: average weight 150 lb. (68 kg) per person
●If the vehicle height cannot be raised when in the normal mode, and “LO” is lit
on the height mode indicator, the vehicle is loaded too heavily. Take extra care
when driving in this condition.
If the vehicle height cannot be raised even after unloading the vehicle, press
“ ▼ ” then “ ▲” on the height mode select switch. If the vehicle height still cannot
be raised, turn the ignition off th en on again, then try once more.

2-4. Using other driving systems
■If the vehicle height does not change
If the vehicle is loaded too heavily, or the undercarriage has come into contact with
the road surface, the vehicle height cannot be raised/lowered. In this case, the indi-
cator 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.)
■In the following cases AHC will not operate
●The brake pedal has been depressed for longer than 5 seconds while the vehi-
cle is stopped.
●The suspension fluid temperature is lower than -22°F (-30°C).
●Driving on bumpy roads which may cause the suspension to fully elongate.
●If the steering wheel is abruptly turned more than 3/4 of a revolution with the
center differential lock system activated.
■Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid tempera-
ture drops below -5°F (-15°C).
AHC does not operate when the suspension fluid temperature drops below -22°F
(-30°C).
●In this case, the selected height mode indicator light will flash when the height
mode select switch is pressed, however the vehicle height will not change.
Once the engine has warmed the suspension fluid to within normal operating
limits, AHC will begin operating and the vehicle height will automatically
change to the selected mode.
●When the suspension fluid is around -22°F (-30°C), the vehicle height may not
be able to be raised, even if AHC is operating. In this case, push “ ▼” then “▲ ”
on the height mode select switch after further warming the engine to select the
desired vehicle height.

2-4. Using other driving systems
AVS (Adaptive Variable Suspension)
■Driving mode
●Mode is suitable for ordinary driving.
●Mode or is suitable for heavy load or driving on a unpaved road.
●With the four-wheel drive control lever at “L”, the damping effect suitable for off-
road driving will be provided.
AVS controls the suspension according to the road and driving conditions.
Selecting an optimum driving mode allows good riding comfort and stabil-
ity.
For driving on a bumpy road
For ordinary driving such as
in the city traffic
For moderate high speed
driving
For sporty type driving such
as on winding mountain
roads and high speed driving
