Roll sensing of curtain shield airbags off
switch
The roll sensing of curtain shield airbags off switch
(RSCA OFFº switch) can turn off the curtain shield
airbags and seat belt pretensioners in a vehicle rollover.
This switch should only be used if inflation is not desired
(such as extreme off-road driving).
When you push the RSCA OFFº switch for a few seconds with
the ignition switch on, the RSCA OFFº indicator light comes
on and the roll sensing function is turned off. When you push
the switch again, the indicator light goes off and the roll sensing
function is turned on. (For details about the roll sensing
function, see SRS side airbags and curtain shield airbagsº on
page 167.)
In a severe side impact, the curtain shield airbags on impacted
side will inflate even if the roll sensing function is turned off.
(For details about the curtain shield airbags, see SRS side
airbags and curtain shield airbagsº on page 167.)In a severe frontal impact, the seat belt pretensioners will work
even if the roll sensing function is turned off. (For details about
the seat belt pretensioners, see ÐSeat belt pretensionersº on
page 149.)
If the ignition switch is turned to ACCº or LOCKº with the roll
sensing function off and then the ignition switch is turned back
to ONº, the roll sensing function will turn back on
automatically.
CAUTION
Before normal driving, make sure the RSCA OFFº
indicator light is off.
When the roll sensing function is turned off (and the
RSCA OFFº indicator light is on), the curtain shield
airbags and seat belt pretensioners will not work in
a vehicle rollover. Turning off the curtain shield
airbags and seat belt pretensioners reduces
occupant protection which your vehicle safety
systems can provide in accidents and increase the
likelihood of death or serious injuries.

Automatic notifications
If an airbag deploys, an emergency signal is sent
automatically to the Lexus Link Call Center. In your vehicle, the
system announces Placing an emergency call to the Lexus
Link Center.º In response to the signal, Lexus Link Advisor will
attempt to communicate with you first. If the Advisor cannot get
any response from you, the Advisor will locate your vehicle
through the GPS, call the nearest emergency services
provider, describe the situation and your location. If necessary,
the Advisor will transfer your call to the emergency services
operator.If the theft deterrent system on your vehicle is activated,
the Lexus Link System on your vehicle will automatically call
the Lexus Link Call Center. The Advisor will attempt to contact
you to determine whether the alarm is valid.
If you report to the Lexus Link Call Center that your vehicle has
been stolen, the Advisor will locate, track and provide location
information to the appropriate law enforcement authority. To
protect subscriber privacy, the Lexus Link Call Center will not
provide the location of a vehicle to anyone other than a law
enforcement authority.
If you accidentally activate the vehicle alarm, push the
UNLOCKº button on the wireless remote control key within 55
seconds after the alarm was set off, or insert the key into the

FUEL PUMP SHUT OFF SYSTEM
The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to ACCº or LOCKº once and start it.
CAUTION
Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system that has been damaged and
it is in need of repair. In this case, do not restart the
engine.
FACTS ABOUT ENGINE OIL
CONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and cooling
the inside of the engine, and plays a major role in maintaining
the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine
oil during normal engine operation. The causes of oil
consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders.
A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder. High negative pressure
generated when the vehicle is decelerating sucks some of
this oil into the combustion chamber. This oil as well as
some part of the oil film left on the cylinder wall is burned by
the high temperature combustion gases during the
combustion process.
Oil is also used to lubricate the stems of the intake valves.
Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems.
