WARNING
■
Replacing light bulbs
●
Turn off the lights. Do not attempt to
replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may
cause burns.
●
Do not touch the glass portion of the
light bulb with bare hands. When it is
unavoidable to hold the glass portion,
use and hold with a clean dry cloth to
avoid getting moisture and oils on the
bulb.
Also, if the bulb is scratched or
dropped, it may blow out or crack.
●
Fully install light bulbs and any parts
used to secure them. Failure to do so
may result in heat damage, fire, or
water entering the headlight unit. This
may damage the headlights or cause
condensation to build up on the lens.
■
To prevent damage or fire
●
Make sure bulbs are fully seated and
locked.
●
Check the wattage of the bulb before
installing to prevent heat damage.

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.
(
If they are damaged, use a towing
dolly or flatbed truck.
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.
324
7-2. Steps to take in an emergency
The following may indicate a problem
with the drivetrain. 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 eyelet to the vehicle
Make sure that towing eyelet is installed
securely.
If not securely installed, towing eyelet
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. (

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.
1
Take out the wheel bolt wrench,
flathead screwdriver and towing
eyelet. (
2
Remove the eyelet cover using a
flathead screwdriver.
To protect the bodywork, place a rag
between the screwdriver and the vehicle
body as shown in the illustration.
