7-2. Steps to take in an emergency
If your vehicle needs to be towed
The following may indicate a problem with your transmission. Contact
your Lexus dealer before towing.
●The hybrid system is operating but the vehicle will not move.
●The vehicle makes an abnormal sound.
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. 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 flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.

■Before emergency towingRelease 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.

Be sure to transport the vehicle with the rear
wheels raised or with all four wheels raised
off the ground. If the vehicle is towed with the
rear wheels contacting the ground, the driv-
etrain and related parts may be damaged or
the motor may generate electricity. If the
motor generates electricity, depending on
the state of the damage or malfunction, a fire
may occur due to a short circuit.

When trouble arises
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
●Do not tow the vehicle from the rear with the power switch off. The steering 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.
