Before emergency towing
Release the parking brake.
Shift the shift lever to N.
Turn the power switch to ACCESSORY (hybrid system off) or ON (hybrid
system operating) mode.
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When transporting the vehicle
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive stress
on the emergency towing eyelets and the cables or chains. Always be cautious
of the surroundings and other vehicles while towing.
If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.
Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.

NOTICE
To prevent causing serious damage to the transmission when towing using a
wheel-lift type truck
Never tow this vehicle from the front with the rear wheels on the ground.
To prevent damage to the vehicle when towing using a wheel-lift type truck

lock mechanism is not strong 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.
To prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
To prevent damage to the vehicle
Do not use the rear tie down hooks when your vehicle is towed.

*3: Seat belt warning buzzer:
The seat belt warning buzzer sounds to alert the driver, front passenger and
rear passengers that his or her seat belt is not fastened. The buzzer sounds for
30 seconds after the vehicle reaches a speed of 20 km/h (12 mph). Then, if the
seat belt is still unfastened, the buzzer will sound in a different tone for 90
more seconds.
Passenger detection sensor, seat belt reminder and warning buzzer
If luggage is placed on a passenger seat, the passenger detection sensor may
cause the warning light to flash and the warning buzzer to sound even if a pas-
senger is not sitting in the seat.
If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empty, refuel the vehicle immediately. The mal-
function indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as soon as
possible.
Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient of the voltage temporarily
drops, the electric power steering system warning light may come on and the
warning buzzer may sound.
When the tire pressure warning light comes on
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
Check the tire inflation pressure and adjust to the appropriate level.
If the warning light does not go out even after several minutes, check that the
tire inflation pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natu-
ral air leaks and tire inflation pressure changes caused by temperature. In this
case, adjusting the tire inflation pressure will turn off the warning light (after a
few minutes).

audio sound.
CAUTION
If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized Lexus

vehicle will become extremely unstable during braking, and the ABS system
may fail, which could cause an accident resulting in death or serious injury.

pressure immediately.
If the tire pressure warning light comes on even after tire inflation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If a tire is
flat, repair the flat tire by using emergency tire puncture repair kit.
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
Vehicles with run-flat tires
Decelerate to the lowest appropriate speed as soon as possible. Do not drive
over 60 km/h (37 mph).
Check and adjust the tire inflation pressure immediately.
