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.

■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.

■Before towing
Check that the following conditions are met:
●The vehicle’s tires are properly inflated. (P. 3 0 2 )
●Trailer tires are inflated according to the trailer manufacturer’s recommenda-
tion.
●All trailer lights work.
●All lights work each time you connect them.
●The trailer ball is set up at the proper height for the coupler on the trailer.
●The vehicle remains level when a loaded or unloaded trailer is hitched. Do not
drive if the vehicle is not level, and check for improper tongue load, overloading,
worn suspension, or other possible causes.
●The trailer cargo is securely loaded.
●The rear view mirrors conform to all applicable federal, state/provincial or local
regulations. If they do not, install rear view mirrors appropriate for towing pur-
poses.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
power train components (engine, transmission, differential, wheel bearings, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide/ Owner’s Manual Sup-
plement/ Scheduled Maintenance”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.

2-5. Driving information
Trailer towing tipsYour vehicle will handle differently when towing a trailer. The 3 main
causes of vehicle-trailer accidents are driver error, excessive speed and
improper trailer loading. Keep the following in mind when towing.
● Before starting out, check the trailer lights and the vehicle-trailer con-
nections. Recheck after driving a short distance.
● Practice turning, stopping and reversing with the trailer attached in an
area away from traffic until you be come accustomed to the feel of the
vehicle.
NOTICE
■When installing a trailer hitch
●Use only the position recommended by your Lexus dealer. Do not install the
trailer hitch on the bumper; this may cause body damage.
●Do not use axle-mounted hitches, as they can cause damage to the axle housing,
wheel bearings, wheels or tires.
■Brakes
Lexus recommends trailers with brakes that conform to all applicable federal and
state/provincial regulations.
■Safety chain
A safety chain must always be used between the towing vehicle and the trailer.
Leave sufficient slack in the chain for turns. The chain should cross under the trailer
tongue to prevent the tongue from droppi ng to the ground in the case that it
becomes damaged or separated. For the correct safety chain installation proce-
dure, ask your Lexus dealer.
■Do not directly splice trailer lights
Directly splicing trailer lights may dama ge your vehicle’s electrical system and
cause a malfunction.
