7-2.Steps to take in an emergency

If your vehicle needs to be
towed

If towing is necessary, we recom-
mend having your vehicle towed by
your Lexus dealer or commercial
towing service, using a wheel-lift
type truck or flatbed truck.

Use a safety chain system for all
towing, and abide by all state/pro-
vincial and local laws.

If towing your vehicle with a
wheel-lift type truck from the front,
the vehicle's rear wheels and axles
must be in good conditions.
(



P.288)

If they are damaged, use a towing
dolly or flatbed truck.

If towing your vehicle with a
wheel-lift type truck, use a towing
dolly. (



P.288, 287)

WARNING

Observe the following precautions.

Failure to do so may result in death or

serious injury.

■

When towing the vehicle



2WD models

Be sure to transport the vehicle with all

four wheels raised off the ground. If the

vehicle is towed with the tires contacting

the ground, the drivetrain and related

parts may be damaged or an accident

may occur due to a change in direction

of the vehicle.



AWD models

Be sure to transport the vehicle with all

four wheels raised off the ground. If the

vehicle is towed with the tires contacting

the ground, the drivetrain or related

parts may be damaged, the vehicle may

fly off the truck.

288

7-2. Steps to take in an emergency

The following may indicate a problem
with your transmission. Contact your
Lexus dealer or commercial towing
service before towing.



The engine is running but the vehi-
cle does not move.



The vehicle makes an abnormal
sound.



From the front

Use a towing dolly under the rear
wheels.

WARNING

■

While towing

●

When towing using cables or chains,

avoid sudden starts, etc. which place

excessive stress on the towing eyelets,

cables or chains. The towing eyelets,

cables or chains may become dam-

aged, broken debris may hit people,

and cause serious damage.

●

Do not turn the engine switch off.

There is a possibility that the steering

wheel is locked and cannot be oper-

ated.

■

Installing towing eyelets to the vehi-

cle

Make sure that towing eyelets are

installed securely.

If not securely installed, towing eyelets

may come loose during towing.

NOTICE

■

To prevent damage to the vehicle

when towing using a wheel-lift type

truck

●

Do not tow the vehicle from the rear

when the engine switch is off. The

steering lock mechanism is not strong

enough to hold the front wheels

straight.

●

When raising the vehicle, ensure ade-

quate ground clearance for towing at

the opposite end of the raised vehicle.

Without adequate clearance, the vehi-

cle could be damaged while being

towed.

■

To prevent damage to the vehicle

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

during emergency towing

Do not secure cables or chains to the

suspension components.

■

Recreational towing (behind motor

home, etc.)

Never dinghy tow your vehicle to pre-

vent causing serious damage to the

AWD system and transmission. (



From the rear

Use a towing dolly under the front
wheels.

When using a flat-bed truck to trans-
port the vehicle, use tire strapping
belts. Refer to the owner's manual of
the flat-bed truck for the tire strapping
method.
In order to suppress vehicle movement
during transportation, set the parking
brake and turn the engine switch off.

If a tow truck is not available in an
emergency, your vehicle may be tem-
porarily towed using cables or chains

secured to the emergency towing eye-
lets. This should only be attempted on
hard surfaced roads for at most 50
miles (80 km) 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.

To have your vehicle towed by another
vehicle, the towing eyelet must be
installed to your vehicle. Install the tow-
ing eyelet using the following proce-
dure.

Take out the wheel nut wrench, flat-
head screwdriver and towing eye-
let. (



P.305)

Remove the eyelet cover using a
flathead screwdriver.

To protect the bodywork, place a rag

between the screwdriver and the vehicle
