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.

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.

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.

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.

DRIVING TIPS
322
Brakes and safety chains
Lexus recommends trailers with brakes that conform to
any applicable federal and state/provincial regulations.
 A safety chain must always be used between the towing
vehicle and the trailer. Leave sufficient slack in the
chain for turns. The chain should cross under the
trailer tongue to prevent the tongue from dropping to
the ground in case it becomes damaged or separated.
For correct safety chain procedures, consult your
Lexus dealer.
CAUTION
If the total trailer weight exceeds 453 kg (1000 lb.),
trailer brakes are required.
 Never tap into your vehicle’s hydraulic system as it
will lower its braking effectiveness.
 Never tow a trailer without using a safety chain
securely attached to both the trailer and the vehicle.
If damage occurs to the coupling unit or hitch ball,
there is possible danger of the trailer wandering over
into another lane.
Tires
Ensure that your vehicle’s tires are properly inflated. Adjust
the tire inflation pressure to the recommended cold tire
inflation pressure indicated below:
Tire inflation pressure, kPa (kgf/cm
2 or bar, psi)
Front 220 (2.2, 32)
Rear 240 (2.4, 35)
 The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the
total trailer weight.

DRIVING TIPS
324
Disconnecting a trailer
Stop your vehicle and a trailer in line and perform the following:
1. Put the active height control suspension in the “LO” mode.
(Make sure the vehicle height is in the “LO” mode by pushing
the height select switch on the “
”side.)
2. Turn the ignition switch off or push the height control switch
to turn off the active height control suspension.
3. Set the supporting leg of a trailer on the ground and raise the
hitch by 100 mm (4 in.).
4. Turn the ignition switch on or push the height control switch
to turn on the active height control suspension.
5. Wait for about 20 seconds until the rear vehicle height is
lowered by the automatic leveling function.
6. Make sure the hitch is disconnected. If not, raise the hitch
higher and repeat steps 2 through 5.
7. Move the vehicle forward in the “LO” mode where the hitch
does not touch anything in the “N” mode.
8. Put the active height control suspension in the “N” mode.
Pretowing safety check
 Check that your vehicle remains level when a loaded or
unloaded trailer is hitched. Do not drive if the vehicle has
an abnormal nose −up or nose− down condition, and check
for improper tongue load, overload, worn suspension or
other possible causes.
 Make sure the trailer cargo is securely loaded so that it
cannot shift.
 Check that your rear view mirrors conform to any federal,
state/provincial or local regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.

DRIVING TIPS
329
Towing capacity:2948 kg (6500 lb.)
Towing capacity means the maximum gross trailer
weight (trailer weight plus its cargo weight) that your
vehicle is able to tow.
Cargo capacity
Cargo capacity may increase or decrease depending on
the size (weight) and the number of occupants. For
details, see “Capacity and distribution” that follows.
CAUTION
Do not apply the load more than each load limit.
That may cause not only damage to the tires, but
also deterioration to the steering ability and
braking ability, which may cause an accident.
CARGO AND LUGGAGE
Stowage precautions
When stowing cargo and luggage in or on the
vehicle, observe the following:
 Put cargo and luggage in the luggage compartment
when at all possible. Be sure all items are secured in
place.
 Be careful to keep the vehicle level. Placing the
weight as far forward as possible helps maintain
vehicle balance.
 For better fuel economy, do not carry unnecessary
weight.
CAUTION
To prevent cargo and luggage from sliding
forward during braking, do not stack anything
in the luggage compartment higher than the
seatbacks. Keep cargo and luggage low, as
close to the floor as possible.

IN CASE OF AN EMERGENCY
340
Stop the vehicle on a level firm ground, firmly
set the parking brake and put the transmission
in “P”. Block the wheel diagonally opposite to
the one being changed if necessary.
 Make sure to set the jack properly in the jack
point. Raising the vehicle with jack improperly
positioned will damage the vehicle or may allow
the vehicle to fall off the jack and cause
personal injury.
 Never get under the vehicle when the vehicle is
supported by the jack alone.
 Use the jack only for lifting your vehicle during
wheel changing.
 Do not raise the vehicle with someone in the
vehicle.
 When raising the vehicle, do not place any
objects on top of or underneath the jack.
 Raise the vehicle only high enough to remove
and change the tire.
NOTICE
Do not continue driving with a deflated tire.
Driving even a short distance can damage a tire
and wheel beyond repair.
