expansion and contraction of the propeller shaft. This does no t indicate a malfunc-
tion. ■

When driving
LX570_OM_OM60L21U_(U) CAUTION■
When switching the vehicle height mode
Before lowering the vehicle height, check that there are no people under or around
the vehicle, and check for obstacles.
If you do not do this, body parts may be caught in the vehicle, possibly leading to an
accident. ■
Using the high mode
The high mode should only be used wh en driving 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, result-
ing in an accident. ■
When jacking up the vehicle or installing tire chains
Turn off the height control and stop the engine, otherwise the vehicle height may
change due to the automatic leveling function and you may catch part of your body
in the vehicle, resulting in an accident. ■
When crossing rivers
Select the high mode and turn off the height control. Drive at 18 mph (30 km/h) or
lower. Otherwise the vehicle height may change due to the automatic leveling func-
tion, resulting in an accident. ■
If your vehicle must be towed
Put the vehicle height in the normal mode and turn off the height control, otherwise
the vehicle height may change due to the automatic leveling function and you may
catch part of your body in the vehicle, resulting in an accident. ■
If your vehicle beco mes stuck in a ditch
Turn off the height control, otherwise the vehicle height may change due to the
automatic leveling function, resulting in an accident. ■
When loading cargo on the roof luggage carrier
Do not switch to high mode. Sudden steeri ng could cause the vehicle to lose stabil-
ity due to the vehicle’s higher center of gravity, possibly leading to an accident.

not extend the vehicle’s performance limitations. Always thoroughly check the road
conditions, and drive safely. ■

fixed low speed, which may result in an accident: ●
Extremely steep inclines. ●
Extremely uneven surfaces. ●
Snow-covered roads, or other slippery surfaces.

When driving
LX570_OM_OM60L21U_(U) NOTICE■
To prevent the water damage
Take all necessary safety measures to en sure that water dama ge to the engine or
other components does not occur. ●
Water entering the engine air intake will cause severe engine damage. ●
Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age. ●
Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.■
When you drive through water
If driving through water, such as when crossing shallow streams, first check the
depth of the water and the bottom of the river bed for firmness. Drive slowly and
avoid deep water. ■
Inspection after off-road driving ●
Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components. ●
Always perform a maintenance inspection after each day of off-road driving that
has taken you through rough terrain, sand, mud, or water. For scheduled mainte-
nance information, refer to the “Warra nty and Services Guide/Owner’s Manual
Supplement/Schedul ed Maintenance”.
