5-1. Essential information
Using a flat bed truckIf your Lexus is transported by a
flat bed truck, it should be tied
down at the locations shown in the
illustration.
If you use chains or cables to tie
down your vehicle, the angles
shaded in black must be 45 .
Do not overly tighten the tie downs
or the vehicle may be damaged.
NOTICE
■To prevent causing serious damage to the transmission and transfer (AWD mod-
els) when towing using a wheel-lift type truck
2WD models: Never tow this vehicle from the front with the rear wheels on the
ground.
AWD models: Never tow this vehicle with any of the wheels in contact with the
ground.
■To prevent damaging the vehicle
●Do not tow the vehicle from the rear with the “ENGINE START STOP” switch
OFF.
The steering lock mechanism is not st rong enough to hold the front wheels
straight.
●When raising the vehicle from the rear, ensure adequate ground clearance for
towing at the opposite end of the raised vehicle. Without adequate clearance, the
vehicle could be damaged while being towed from the rear.

5-2. Steps to take in an emergency
CAUTION
■When the electric power steering warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, firmly hold and
operate it using more force than usual.
■If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately.
●If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat ti re. Check the tires. If the tire is flat,
change to the spare tire and have the flat tire repaired by the nearest Lexus
dealer.
●Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.
■If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

5-2. Steps to take in an emergency
If your vehicle has to be stopped in an emergency
CAUTION
■If the engine has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the brake pedal
harder to depress and the steering wheel heavier to turn. Decelerate as much as
possible before turning off the engine.
Only in an emergency, such as if it becomes impossible to stop the vehicle
in the normal way, stop the vehicle using the following procedure:
Steadily step on the brake pe dal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N After slowing down, stop the vehicl e in a safe place by the road.
Stop the engine.
If the shift lever cannot be shifted to N Keep depressing the brake pedal with both feet to reduce vehi-
cle speed as much as possible.
Stop the engine by pressing and
holding the “ENGINE START
STOP” switch for 2 consecutive
seconds or more, or press it
briefly 3 times or more in suc-
cession.
Stop the vehicle in a safe place by the road.

Vehicle specifications
■Temperature A, B, C
The temperature grades are A (the hi ghest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissipate
heat when tested under controlled conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive temperature can lead to sudden tire fail-
ure.
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federal Mo tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of performance on the laboratory
test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a tire that
is properly inflated and not overloaded.
Excessive speed, underinflation, or excess ive loading, either separately or in
combination, can cause heat build up and possible tire failure.
