response-center agent, who can help
with a wide range of needs, such as:
towing, flat tire, fuel delivery, etc. For a
description of the Roadside Assistance

Important! Read this information about
exposure to radio frequency signals
before using Safety Connect;
The Safety Connect system installed in
your vehicle is a low-power radio trans-
mitter and receiver. It receives and also
sends out radio frequency (RF) signals.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.
ANSI (American National Stan-
dards Institute) C95.1 [1992]
 NCRP (National Council on Radia-
tion Protection and Measurement)
Report 86 [1986]
 ICNIRP (International Commission
on Non-Ionizing Radiation Protec-
tion) [1996]
Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physi-
cians from universities, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com-
plies with the FCC guidelines in addi-
tion to those standards.

Before driving
nor “R”.
To set the mirror angle used when the vehi-
cle is reversing, adjust the mirror angle at a
desired position with the shift lever in R.
The adjusted angle will be memorized and
the mirror will automatically tilt to the mem-
orized angle whenever the shift lever is
shifted to R from next time.
The memorized downward tilt position of
the mirror is linked to the normal position
(angle adjusted with the shift lever in other
than R). Therefore, if the normal position is
changed after adjustment, the tilt position
will also change.
When the normal position is changed, read-
just the angle in reversing.
Push the mirror back in the direction of
the vehicle’s rear.
■Using the switch
Press the switch to fold the mirrors.
Press it again to extend them to the original
position.
■Setting automatic mode
Automatic mode allows the folding or
extending of the mirrors to be linked to
locking/unlocking of the doors.
Press the “AUTO” switch to set auto-
matic mode.
The indicator will come on.
Pressing the switch on ce more will return
to manual mode.
■When disconnecting and reconnecting
battery terminals (power type)
The automatic folding/extending mirror
function will return to off as default. To turn
the function on, press the switch again to
select on.
■Using automatic mode in cold weather
(if equipped)
When automatic mode is used in cold
weather, the door mirror could freeze up
and automatic stowing and return may not
be possible. In this case, remove any ice and
WARNING
■When the mirror defoggers are oper-
ating

gage load capacity calculated in Step
4.
(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
( P.164)
Vehicles without towing package: Lexus
does not recommend towing a trailer with
your vehicle. Your vehicle is not designed
for trailer towing.
Cargo capacity
Total load capacity (vehicle capac-
ity weight) ( P.452)
When 2 people with the combined
weight of A lb. (kg) are riding in your
vehicle, which has a total load capacity
(vehicle capacity weight) of B lb. (kg),
the available amount of cargo and lug-
gage load capacity will be C lb. (kg) as
follows:
B
*2 lb. (kg) - A*1 lb. (kg) = C*3 lb. (kg)
*1: A =Weight of people
*2: B =Total load capacity
*3: C =Available cargo and luggage load
In this condition, if 3 more passengers with
the combined weight of D lb. (kg) get on,
the available cargo and luggage load will
be reduced E lb. (kg) as follows:
C lb. (kg) - D*4 lb. (kg) = E*5 lb. (kg)
*4: D =Additional weight of people
*5: E =Available cargo and luggage load
As shown in the example above, if the
number of occupant s increases, the
cargo and luggage load will be
reduced by an amount that equals the
increased weight due to the additional
occupants. In other words, if an
increase in the number of occupants
causes an excess of the total load
capacity (combined weight of occu-
pants plus cargo and luggage load),
you must reduce the cargo and lug-
gage on your vehicle.

WARNING
■Things that must not be carried in the
luggage compartment

possibly causing an accident.
●Stow cargo and luggage in the lug-
gage compartment whenever possi-
ble.
