Automatic Collis ion Notification
In case of either airbag deployment or severe rear-end collision, the system is
designed to automatically call the response center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicle occu-
pants to assess the level of emergency. If the occupants are unable to commu-
nicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be se nt to the location.■
Stolen Vehicle Location
If your vehicle is stolen, Safety Connect can work with local authorities to
assist them in locating and recovering the vehicle. After filing a police report,
call the Safety Connect response center at 1-800-25-LEXUS
(1-800-255-3987) and follow the prompts for Safety Connect to initiate this
service.
In addition to assisting law enforcement with recovery of a stolen vehicle,
Safety-Connect-equipped vehicle location data may, under certain circum-
stances, be shared with third parties to locate your vehicle. Further informa-
tion is available at Lexus.com. ■
Emergency Assistance Button (“SOS”)
In the event of an emergency on the ro ad, push the “SOS” button to reach the
Safety Connect response center. Th e answering agent will determine your
vehicle’s location, assess the emergency, and dispatch the necessary assis-
tance required. If you accidentally press the “SOS” button, tell the response-center agent that you
are not experiencing an emergency.■
Enhanced Roadside Assistance
Enhanced Roadside Assistance adds GP S data to the already included war-
ranty-based Lexus roadside service.
Subscribers can press the “SOS” button to reach a Safety Connect response-
center agent, who can help with a wide range of needs, such as: towing, flat

the dipstick. ■
Checking the engine oil
Park the vehicle on level ground. After warming up the engine and turning
off the hybrid system, wait more than 5 minutes for the oil to drain back into
the bottom of the engine.
Holding a rag under the end, pull
the dipstick out.
Wipe the dipstick clean.
Reinsert the dipstick fully with its
protruding areas ( in the illus-
tration) pointing towards engine.

Adding engine oil
If the oil level is below or near the
low level mark, add engine oil of the
same type as that already in the
engine.
Make sure to check the oil type and prepare the items needed before adding
oil.
Remove the oil filler cap by turning it coun terclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise. ■
Engine oil consumption
A certain amount of engine oil will be consum ed while driving. In th e following situations,
oil consumption may increase, and engine o il may need to be refilled in between oil
maintenance intervals. ●
When the engine is new, for example directly after purchasing the vehicle or after
replacing the engine ●

Situations in which the tire pressure warning system may not operate properly ●
In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• Lock nuts are equipped.
• An auxiliary-supported run-flat tire is equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the wheels or wheel
housings.
• If the tire inflation pressure is extremely higher than the specified level.
• If wheel without the tire pressure warning valve and transmitter is used.
• If the ID code on the tire pressure warning valves and transmitters is not registered
in the tire pressure warning computer. ●
Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air-
port or other facility th at generates strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless ph one or other wireless
communication device ●
When the vehicle is parked, the time taken for the warning to start or go off could be
extended. ●
When tire inflation pressure declines rapidly for example when a tire has burst, the
warning may not function. ■
The initialization operation ●
Make sure to carry out initialization af ter adjusting the tire inflation pressure.
Also, make sure the tires are cold before carry ing out initialization or tire inflation pres-
sure adjustment. ●
If you have accidentally turned the power swit ch off during initializat ion, it is not neces-
sary to press the reset switch again as init ialization will restart automatically when the
power switch has been turned to ON mode for the next time. ●
If you accidentally press the reset switch when initialization is not necessary, adjust the
tire inflation pressure to the specified leve l when the tires are co ld, and conduct initial-
ization again. ■
Warning performance of the tire pressure warning system
The warning of the tire pressure warning syst em will change in accordance with the con-
ditions under which it was initialized. For this reason, the system may give a warning even
if the tire pressure does not reach a low enough level, or if the pressure is higher than the
pressure that was adjusted to when the system was initialized. ■
When initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases, the set-
tings have not been recorded and the system will not operate properly. If repeated
attempts to record tire inflation pressure settings are unsuccessful, have the vehicle
inspected by your Lexus dealer. ●
When operating the tire pressure warning reset switch, the tire pressure warning light
does not blink 3 times. ●
After carrying out the initializ ation procedure, the tire pres sure warning light blinks for
1 minute then stays on after driving for 20 minutes.

When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dangerous han-
dling characteristics, which may lead to an accident resultin g in death or serious injury.●
Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear. ●
Do not use tire sizes other than those recommended by Lexus. ●
Do not mix differently constructed tires (radial, bias-belted or bias-ply tires). ●
Do not mix summer, all season and snow tires. ●
Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously. ●
Vehicles with a compact spare tire: Do no t tow if your vehicle has a compact spare
tire installed. ■
When initializing the tire pressure warning system
Do not initializing tire inflation pressure wi thout first adjusting the tire inflation pressure
to the specified level. Otherwise, the tire pressure warning light may not come on even
if the tire inflation pressure is low, or it may come on when the tire inflation pressure is
actually normal. ■
Caution regarding interference with electronic devices
●
Users of any electrical medical device other than implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemakers or implantable cardioverter defibril-
lators should consult the ma nufacturer of the device for information about its opera-
tion under the influence of radio waves.
Radio waves could have unexpected effe cts on the operation of such medical
devices. ●
People with implantable cardiac pacemakers,
cardiac resynchronization therapypacemak-
ers or implantable cardioverter defibrillators
should not come within 17.7 in. (450 mm) of
the tire pressure warning system initiators.
The radio waves may affect the operation of
such devices.
