2-4. Using other driving systems
CAUTION
■While driving
●This system should be used as a supplemental aid to help you see objects. Never
depend on this system only. Be sure to view objects with your own eyes.
●This system is designed to help you see objects better when driving in a flat area
with few curves in darkness. Use of this function in an area with many curves or
slopes or in a well-lit area could cause an accident.
■Conditions which may affect the Lexus night view system
●If the front bumper is deformed in a collision, etc., the performance of the near-
infrared floodlight will be affected. Have it repaired or replaced by your Lexus
dealer.
●If you notice the inner lens of the near-infrared camera is dirty, have it inspected
by your Lexus dealer.
●If the top of the windshield fogs up, the lens of the near-infrared camera will also
fog up, resulting in deterioration of the system performance. Defog the wind-
shield by pushing the windshield air flow button on the air conditioning.
●If the outside temperature is low, the head-up display may darken or it may take
time to display the image with the system on.
●The automatic light control sensor may not function properly if an object is placed
on the sensor, or anything that blocks the sensor is affixed to the windshield.
■To a v o i d i n j u r y
The near-infrared floodlight irradiates stro ng energy nut visible to the eyes. Do not
stare at the floodlight at close range for a long time.

2-5. Driving information
●Due to the added load of the trailer, your vehicle’s engine may overheat
on hot days (at temperatures over 85
F[30C] when driving up a long
or steep grade. If the engine coolant temperature gauge indicates
overheating, immediately turn off th e air conditioning (if in use), pull
your vehicle off the road and stop in a safe spot. (
P. 363)
● Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the pa rking brake firmly, and put the
transmission in P. Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel blocks under both the vehicle and
trailer wheels.
When the wheel blocks are in pl ace, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into “P” and turn off the engine.
● When restarting after parking on a slope:
With the transmission in the “P” position, start the engine. Be sure
to keep the brake pedal pressed.
Shift into 3, 2, 1, or “R” position (if reversing).
Release the parking brake and br ake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
