The symbol on a child restraint system indicates the presence
of a lower connector system.
If your child restraint system has a top strap, it should be
anchored. (For the installation of the top strap, see “Using a top
strap” on page 184.)
For installation details, refer to the instruction manual
equipped with each product.
CAUTION

When using the lower anchorages for the child
restraint system, be sure that there are no irregular
objects around the anchorages or that the seat belt is
not caught.
 Push and pull the child restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided by its
manufacturer.
 After securing the child restraint system, never
recline the seat.
 Do not install a child restraint system on the third
seat if it interferes with the lock mechanism of the
second seat. Otherwise, the child or second seat
occupant(s) may be killed or seriously injured in
case of sudden braking or a collision.

THE REAR VIEW MONITOR SYSTEM CAMERA
31x602b
The rear view monitor system camera is located on the back
door as shown in the illustration. The camera uses a special
lens. The distance of the image that appears on the screen
differs from the actual distance.
In the following cases, it may become difficult to see the images
on the screen, even when the system is functioning.

In the dark (for example, at night)
 When the temperature near the lens is extremely high or low
 When water droplets are adhering to the camera, or when
humidity is high (for example, when it rains)
 When foreign matter (for example, snow or mud) adheres
to the camera lens
 When the sun or the beam of headlights is shining directly
into the camera lens
31x603
Check surroundings for safety.
If a bright light (for example, sunlight reflected off the vehicle
body) is picked up by the camera, the smear effect* peculiar
to the camera may occur.
*: Smear effect — A phenomenon that occurs when a bright
light (for example, sunlight reflected off the vehicle body) is
picked up by the camera; when transmitted by the camera, the
light source appears to have a vertical streak above and below
it.

STARTING AND DRIVING
274In the following conditions, the image may not be clear or the
view of the road ahead may not be shown at all.

Driving on hills with many up and down slopes
 Driving on road with curves
 In severe weather conditions such as rain, fog or snow
 Strong near −infrared light emission, such as the light
coming from a vehicle running in the opposite lane, enters
the near− infrared camera (night view camera).
 An object or clothing of a pedestrian is made of a certain kind
of material (ex. leather).
 The windshield or the lens of the near −infrared floodlight
(night view projector) is dirty. (Always keep the windshield
and the lens clean.)
 Double vision of image reduces clarity in some situation.
 The top of the windshield fogs up.
If the top of the windshield fogs up, the glass in front of the lens
of the camera will also fog up, resulting in deterioration of the
system performance. Defog the windshield by pushing the
windshield air flow button on the air conditioning.
If you notice the inner lens of the near −infrared camera (night
view camera) is dirty, have it inspected at your Lexus dealer.
You cannot use this system to read a road sign or signboard.
If the outside temperature is low, the display may darken or it
may take time to display the image with the system on. The near
−infrared floodlight (night view projector) is installed
on the bumper. If the bumper is deformed in a collision, etc.,
the performance of the system will be affected. Have it
repaired or replaced at Lexus dealer.
CAUTION
The nearinfrared floodlight (night view projector)
irradiates strong energy not visible to the eyes. Do not
stare at the floodlight at close range for a long time.
Your eyes could be seriously injured.
NOTICE
 Do not put anything in front of the headup display
(night view display) shutter. It may hinder the
opening or closing of the shutter, resulting in a
malfunction of the system.
 Do not let drinks spill on the headup display. This
may cause a malfunction of the system.
 If an object gets caught in the shutter and it does not
close securely, it may cause a malfunction of the
system. Open the shutter with your hand and remove
the object. The shutter will function properly after
you turn the ignition off and then on.

Replacing tires and wheels
When replacing the tires and wheels, be sure to install tire
pressure warning valves and transmitters. ID codes on the tire
pressure warning valves and transmitters are registered on the
tire pressure warning ECU. When replacing a tire pressure
warning valve and transmitter, it is necessar y to register the ID
code of tire pressure warning valve and transmitter. Have the
ID code registered by your Lexus dealer.
If the ID code is not registered, the system will not work
properly. After about 1 hour, the tire pressure warning light
blinks to indicate a system malfunction.
NOTICE
When the tires or tire pressure warning valves and
transmitters must be replaced, have them replaced by
your Lexus dealer. The tire pressure warning valves
and transmitters will be affected by the installation or
removal of tires.
Tire pressure warning reset switch
31x612
When initializing the system, the present tire inflation pressure
is stored as standard. The tire pressure warning system
determines decreased air pressure by comparing the present
and the standard tire inflation pressures. When you change
the set tire inflation pressure, it is necessary to initialize the tire
pressure warning system.
 When rotating the tires on vehicles differing with front and
rear tire inflation pressures.
 When changing the tire inflation pressure by changing
traveling speed or load weight, etc.
 When changing the tire size.

DRIVING TIPS
313
Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.
 If you drive through deep water over about 500 mm
(20 in.) in depth, put the vehicle height in the HI (High)
mode with the active height select switch and then
turn off the active height control suspension by
pushing the height control switch. Drive your vehicle
at 30 km/h (19 mph) or lower speed.OFFROAD DRIVING PRECAUTIONS
When driving your vehicle off −road, please observe the
following precautions to ensure your driving enjoyment and to
help prevent the closure of areas to off −road vehicles.
a. Drive your vehicle only in areas where off −road vehicles are
permitted to travel.
b. Respect private property. Get owner’s permission before
entering private property.
c. Do not enter areas that are closed. Honor gates, barriers
and signs that restrict travel.
d. Stay on established roads. When conditions are wet,
driving techniques should be changed or travel delayed to
prevent damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your
vehicle off −road, consult the following organizations.
 State and Local Parks and Recreation Departments
 State Motor Vehicle Bureau
 Recreational Vehicle Clubs
 U.S. Forest Service and Bureau of Land Management

Hitches
If you wish to install a trailer hitch, you should consult with
your Lexus dealer.
 Use only a hitch recommended by the hitch manufacturer
and the one which conforms to the total trailer weight
requirement.
 The hitch must be bolted securely to the vehicle frame and
installed according to the hitch manufacturer’s instructions.
 The hitch ball and king pin should have a light coat of
grease.
 Lexus recommends removing the trailer hitch whenever
you are not towing a trailer to reduce the possibility of
additional damage caused by the hitch if your vehicle is
struck from behind. After removing the hitch, seal any
mounting holes in the vehicle body to prevent entry of
pollutants such as exhaust fumes, dirt, water, etc.
NOTICE
Do not use axlemounted hitches as they can cause
damage to the axle housing, wheel bearings, wheels or
tires. Also, never install a hitch which may interfere with
the normal function of an Energy Absorbing Bumper, if
so equipped.
Trailer ball
Follow these easy steps to properly determine the correct
trailer ball for your application:
1. Determine the correct trailer ball size for the trailer coupler.
Most couplers are stamped with the required trailer ball size.
The sizes you’ll most likely find stamped on the coupler are:
Trailer Class
Typical Trailer Ball Size
III 2 in.
II 2 in.
I 1 7/8 in.
2. Select the appropriate trailer ball to match or exceed the
gross trailer weight rating of the trailer. The trailer ball load
rating should be printed on the top of the ball.
