CAUTION
●If your vehicle needs to be towed, do so with front wheels raised. If the wheels
connected to the electric motor (traction motor) are on the ground when towing,
the motor may continue to generate electricity. This may cause an electricity
leakage leading to a fire. (
→P. 4 9 5 )
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked
onto the ground, the fuel system may have been damaged. Leave the vehicle as
soon as possible.
■Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improp-
erly, it is hazardous to the environment and there is a risk of severe burns and elec-
trical shock that may result in death or serious injury.
■Emergency shut off system
Carefully check to see if there are exposed high voltage parts or cables. Never
touch the parts or cables. (
→P. 3 0 )
NOTICE
■Hybrid battery air vent
●Do not put foreign objects near the air vent. The hybrid battery (traction battery)
may overheat and be damaged.
●Clean the air vent regularly to prevent the hybrid battery (traction battery) from
overheating.
●Do not wet or allow foreign substances to enter the air vent as this may cause a
short circuit and damage the hybrid battery (traction battery).
●Do not carry large amounts of water such as water cooler bottles in the vehicle. If
water spills onto the hybrid battery (traction battery), the battery may be dam-
aged. Have the vehicle inspected by your Lexus dealer.

If your vehicle needs to be towed
Before towingThe following may indicate a problem with your hybrid transmission.
Contact your Lexus dealer before towing.
● The hybrid system is operating but the vehicle will not move.
● The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency
towing eyelet(s). This should only
be attempted on hard surfaced
roads for short distances at under
18 mph (30 km/h).
A driver must be in the vehicle to
steer and operate the brakes. The
vehicle’s wheels, drive train, axles,
steering and brakes must be in
good condition.
If towing is necessary, we recommend having your vehicle towed by your
Lexus dealer or a commercial towing service, using a lift-type truck or a
flatbed truck.
Use a safety chain system for all towing, and abide by all state/provincial
and local laws.

●Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which would place excessive
stress on the emergency towing eyelets and the cables or chains. Always be cau-
tious of the surroundings and other vehicles while towing.
●Do not turn off the power switch.
This may lead to accidents as the parking lock will be engaged.
●If the hybrid system is off, the power assist for the brakes and steering will not
function, making steering and braking more difficult.

lead to accidents that cause serious injury or even death.
