by the jack.
●Do not raise the vehicle while some-
one is inside.
●When raising the vehicle, do not put an
object on or under the jack.
●Do not raise the vehicle to a height
greater than that required to replace
the tire.
●Use a jack stand if it is necessary to get
under the vehicle.
●Make sure to disable all functions of
the vehicle height control of the elec-

4227-2. Steps to take in an emergency
In the following situations, it is not pos-
sible to be towed by another vehicle
using cables or chains, as the rear
wheels may be locked due to the park-
ing lock. Contact your Lexus dealer or
commercial towing service.
There is a malfunction in the P posi-
tion control system. ( P.177, 436)
 There is a malfunction in the engine
immobilizer system. ( P.64)

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.
●Make sure to disable all functions of
the vehicle height control of the elec-
tronically modulate d air suspension.
Otherwise, the vehicle height may
change and part of your body may be
caught under the vehicle, possibly
causing injury. (
P.303)
●Do not turn the engine switch off.
This may lead to an accident as the
rear wheels will be locked by the park-
ing lock.
■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.) (AWD models)
Never dinghy tow your vehicle to pre-
vent causing serious damage to the
AWD system and transmission. ( P.173)
