If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission.
Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional, before towing.
The engine is running, 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 emer-
gency towing eyelet(s). This should only be attempted on hard,
surfaced roads for short distances at low speeds.
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
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, such as a commercial towing service, using a
lift-type truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.
If towing from the rear, the vehicle's front wheels and axles must be in
good condition. (P. 463)
If they are damaged, use a towing dolly or flat bed truck.

Release the parking brake.
Shift the shift lever to N.
Put the “ENGINE START STOP” switch in ACCESSORY mode
or IGNITION ON mode.
CAUTION
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 engine is not running, the power assist for the brakes and steering
will not function, making steering and braking more difficult.
NOTICE
To prevent causing serious damage to the transmission
(vehicles with an automatic transmission)
Never tow this vehicle from the front with the rear wheels on the ground.
This may cause serious damage to the transmission.
When towing a vehicle without using a towing dolly
(vehicles with a manual transmission)
The “ENGINE START STOP” switch must not be OFF.

Using a flat bed truck
If 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 damaging the vehicle
Do not tow the vehicle from the rear with the “ENGINE START STOP”
switch OFF.
The steering lock mechanism is not strong enough to hold the front wheels
straight.
When raising the vehicle, 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.
