STARTING AND DRIVING
341 Avoid racing the engine.
Do not push−start or pull−start your vehicle.
Do not turn off the engine while the vehicle is moving.
Keep your engine in good running order.
Malfunctions in the engine electrical system,
electronic ignition system or fuel system could cause
an extremely high three−way catalytic converter
temperature.
If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check−up as
soon as possible. Remember, your Lexus dealer
knows your vehicle and its three−way catalytic
converter system best.
To ensure that the three−way catalytic converter and
the entire emission control system operate properly,
your vehicle must receive the periodic inspections
required by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to the
“Owner’s Manual Supplement / Scheduled
Maintenance”.
ENGINE EXHAUST CAUTION
CAUTION
Avoid inhaling the engine exhaust. It contains
carbon monoxide, which is a colorless and odorless
gas. It can cause unconsciousness or even death.
Make sure the exhaust system has no holes or loose
connections. The system should be checked from
time to time. If you hit something, or notice a change
in the sound of the exhaust, have the system checked
immediately.
Do not run the engine in a garage or enclosed area
except for the time needed to drive the vehicle in or
out. The exhaust gases cannot escape, making this
a particularly dangerous situation.
Do not remain for a long time in a parked vehicle with
the engine running. If it is unavoidable, however, do
so only in an unconfined area and adjust the heating
or cooling system to force outside air into the vehicle.
Keep the trunk lid closed while driving. An open or
unsealed trunk lid may cause exhaust gases to be
drawn into the vehicle.

To allow proper operation of your vehicle’s
ventilation system, keep the inlet grilles in front of the
windshield clear of snow, leaves, or other
obstructions.
If you smell exhaust fumes in the vehicle, drive with
the windows open and the trunk lid closed. Have the
cause immediately located and corrected.OPERATING THE ENGINE SWITCH

CAUTION
Never depend on the rear view monitor system
entirely when backing up. Always make sure your
intended path is clear.
Use caution just as you would when backing up any
vehicle.
Never back up while looking only at the screen. The
image on the screen is different from actual
conditions. Depicted distances between objects and
flat surfaces will differ from actual distances. If you
back up while looking only at the screen, you may hit
a vehicle, a person or an object. When backing up, be
sure to check behind and all around the vehicle
visually and with mirrors before proceeding.
Do not use the system when the trunk is not
completely closed.
If the back of the vehicle is hit, the position and
mounting angle of the camera may change. Be sure
to have the camera’s position and mounting angle
checked at your Lexus dealer.
If the temperature changes rapidly, such as when hot
water is poured on the vehicle in cold weather, the
system may not operate normally.
If the camera lens becomes dirty, it cannot transmit
a clear image. If water droplets, snow, or mud adhere
to the lens, rinse with water and wipe with a soft cloth.
If the lens is extremely dirty, wash it with a mild
cleanser and rinse.
Use your own eyes to assure rearward clearance, as
the displayed image may become faint or darker, and
moving images will be distorted or not entirely visible
when outside temperature is cold. When backing up,
be sure to check behind and all around the vehicle
visually and with mirror before proceeding.

STARTING AND DRIVING
391 REAR VIEW MONITOR SYSTEM CAMERA
G31078
The rear view monitor system camera is located on the trunk
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
31L357
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

CAUTION
Under certain conditions where the vehicle in front
slows drastically, or is stopped, the dynamic radar
cruise control will neither warn you nor decelerate. The
driver must depress the brake pedal to slow down,
ensuring collision avoidance or that sufficient
vehicle−to−vehicle distance is maintained.
When vehicle−to−vehicle distance control mode is activated,
you must still be attentive to road and traffic conditions. Should
your vehicle speed decrease below about 40 km/h (25 mph),
the dynamic radar cruise control will shut off, requiring you to
apply the brakes to slow. When a vehicle ahead slows
suddenly, stops or a vehicle cuts in front, the system may slow
your vehicle abruptly, but the automatic braking will cease if the
speed decreases below about 40 km/h (25 mph) requiring the
driver’s manual application of brakes.
CAUTION
Certain conditions make vehicle detection difficult or
impossible.
As this system operates by detecting primarily the
reflected wave from the rear end of the vehicle ahead,
the distance cannot be accurately detected in the
following cases, resulting in improper
vehicle−to−vehicle distance.
♦The rear section of the vehicle ahead is extremely
small such as an unloaded trailer.
♦The vehicle ahead or other vehicles around you
are flinging up water or snow.
♦Heavy luggage which is loaded in your trunk or on
top of your rear seats is raising up the nose of your
vehicle.
The millimeter wave radar sensor automatically
detects dirt if it is sticking to the front of the sensor
or cover of your vehicle, and if detected, a message
appears on the multi−information display. However,
if the sensor or cover is covered with a metallic vinyl
bag, icicle, snowflakes, etc., dirt may not be detected,
resulting in improper vehicle−to−vehicle distance.
Continue driving with due care to the vehicle ahead.
If dirt is detected, the dynamic radar cruise control
function is automatically cancelled. Always keep the
sensor and cover clean.
