CAUTION
■Front passenger occupant classification system precautions
●If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
iminated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator still remain illuminated, either ask the pas-
senger to move to the rear seat, or if that is not possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a forward-facing child restraint system on the
front passenger seat, install the child restraint system on the front passenger seat
in the proper order. (→P. 1 5 2 )
●Do not modify or remove the front seat.
●Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction in the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Child restraint systems installed on the second seat should not contact the front
seatbacks.
●Do not use a seat accessory, such as a cushion and seat cover, that covers the
seat cushion surface.
●Do not modify or replace the upholstery of the front seat.

result:
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage
compartment etc.)
●When the road curves or when the lanes are narrow

■When lowering the vehicle
In order to prevent the vehicle height from rising as occupants leave the vehicle,
lowering control will occur for a short while after the engine has been stopped.
■The rear height control air suspension failure warning
●If a malfunction occurs in the rear height control air suspension, N mode is auto-
matically selected. However, the system may not switch to N mode depending
on the location of the malfunction.
●The warning message is displayed on the multi-information display, and the rear
height control air suspension cannot be activated until the malfunction is cor-
rected.
Stop the engine and start it again. If the warning message turns off, the system is
operating correctly. If the warning message continues to be displayed, have
your vehicle inspected by your Lexus dealer as soon as possible.
CAUTION
■The rear height control air suspension must be turned off when
In the following situations, the automatic leveling function may cause vehicle height
to change, resulting in an unexpected accident:
●When jacking up the vehicle, installing tire chains or tying the vehicle with chains/
wires for transportation via flat bed truck (Turn off the rear height control air sus-
pension and stop the engine.)
●When the vehicle must be towed or disconnecting a trailer (Put the vehicle height
in N mode and turn off the rear height control air suspension.)

Maintenance and care
GX460_CANADA (OM60F29U)
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to expose the
fabric or bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage
If you are not sure, consult with your Lexus dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not registered,
the tire pressure warning system will not work properly. After driving for about 20
minutes, the tire pressure warning light comes on after blinking for 1 minute to indi-
cate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even if they
have seldom or never been us ed or damage is not obvious.
■If the tread on snow tires wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of the tire as snow tires is lost.
■Maximum load of tire
Check that the number given by dividing the maximum load by 1.10 of the replace-
ment tire is greater than 1 /2 of the Gross Axle Weight Ratings (GAWR) of either
the front axle or the rear axle, whichever is greater.
For the GAWR, see the Certification Label.
For the maximum load of the tire, see the load
limit at maximum cold tire inflation pressure
mentioned on the sidewall of the tire.
