Before driving
CAUTION
nSRS airbag precautions
lDo not place anything, such as a cushion, on the front passenger's seat. Doing so
will disperse the passenger's weight, which prevents the sensor from detecting
the passenger's weight properly. As a result, the SRS front passenger airbag may
not deploy in the event of a collision.
nModification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications with-
out consulting your Lexus dealer.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing death or
serious injury.
lInstallation, removal, disassembly and repair of the SRS airbags
lRepairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side
rails
lRepairs or modifications of the front fender, front bumper, or side of the occupant
compartment
lInstallation of snow plows, winches, etc. to the front grille (bull bars or kangaroo
bar etc.)
lModifications to the vehicle's suspension system
lInstallation of electronic devices such as mobile two-way radios or CD players
lModifications to your vehicle for a person with a physical disability

When driving
CAUTION
nOff-road driving precautions
Always observe the following precautions to minimize the risk of death or serious
injury or damage to your vehicle:
lDrive carefully when off the road. Do not take unnecessary risks by driving in
dangerous places.
lDo not grip the steering wheel spokes when driving off-road. A bad bump could
jerk the wheel and injure your hands. Keep both hands and especially your
thumbs on the outside of the rim.
lAlways check your brakes for effectiveness immediately after driving in sand,
mud, water or snow.
lAfter driving through tall grass, mud, rock, sand, water, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped to the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these
materials trapped or adhering to the underbody, a breakdown or fire could occur.
lWhen driving off-road or in rugged terrain, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control or vehi-
cle rollover causing death or serious injury. You are also risking expensive dam-
age to your vehicle’s suspension and chassis.
NOTICE
nTo prevent water damage
Take all necessary safety measures to ensure that water damage to the engine or
other components does not occur.
lWater entering the engine air intake will cause severe engine damage.
lWater entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
lWater 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.
