NOTICE
■Conditions which may affect the rear view monitor system
●If the back of the vehicle has been hit, the camera’s position and mounting angle
may have changed. Have the vehicle inspected by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional.
●Rapid temperature changes, such as when hot water is poured on the vehicle in
cold weather, may cause the system to function abnormally.
●If the camera lens is dirty, it cannot transmit a clear image. Rinse with water and
wipe with a soft cloth. If extremely dirty, wash with a mild cleanser and rinse.
●The displayed image may be darker and moving images may be slightly distorted
when the system is cold.
■Camera precautions
●As the camera has a water proof construction, do not detach, disassemble or
modify it. This may cause incorrect operation.
●Do not subject the camera to a strong impact.
●If the camera lens becomes dirty, it cannot transmit a clear image. If water drop-
lets, 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. Do not rub hard.
●Do not allow organic solvent, car wax, window cleaner or glass coat to adhere to
the camera. If this happens, wipe it off as soon as possible.
●Do not strongly rub the camera lens. If the camera lens is scratched, it cannot

■When the message is displayed on the multi-information display showing that
TRC has been disabled even if the VSC off switch has not been pressed
TRC and hill-start assist control cannot be operated. Contact your any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
■Sounds and vibrations caused by the ABS, VSC, TRC and brake assist
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in any of these systems.
●Any of the following conditions may occur when the above systems are operat-
ing. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■Reactivation of the TRC/VSC systems
Turning off the engine after turning off the TRC/VSC systems will automatically
reactivate them.
■Reactivation of the TRC system linked to vehicle speed
When only the TRC system is turned off, the TRC system will turn on when vehicle
speed increases. However, when both TRC and VSC systems are turned off, the
systems will not turn on even when vehicle speed increases.
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from over-
heating when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from excessive
steering input or stop the vehicle and turn the engine off. The EPS system should
return to normal within 10 minutes.

CAUTION
■When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may cause
an accident, resulting in death or serious injury. Exercise particular care when the
indicator light flashes.
■When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road conditions. As
these are the systems to help ensure vehicle stability and driving force, do not turn
the TRC/VSC systems off unless necessary.
■Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total load
capacity. In addition, make sure that the tires are inflated to the recommended tire
inflation pressure level.
The ABS and VSC systems will not function correctly if different tires are installed
on the vehicle.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, for further information when replacing tires or wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect the driv-
ing assist systems, and may cause a system malfunction.

Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions.
■Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tempera-
tures.
• Engine oil
• Engine coolant
• Washer fluid
●Have a service technician inspect the condition of the battery.
●Have the vehicle fitted with four snow tires or purchase a set of
tire chains for the front tires.
Ensure that all tires are the same size and brand, and that chains match
the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing.
●To ensure proper operation of the climate control system fan,
remove any snow that has accumulated on the air inlet vents in
front of the windshield.
●Check for and remove any excess ice or snow that may have
accumulated on the exterior lights, vehicle's roof, chassis, around
the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before
getting in the vehicle.

2-5. Driving information
RX350/270_EE■Important points regarding turning
The wheels of the trailer will travel closer to the inside of the curve than
the wheels of the vehicle. To make allowance for this, take the turns
wider than you would normally do.
■Important points regarding stability
Vehicle movement resulting from uneven road surfaces and strong
crosswinds will affect handling. The vehicle may also be rocked by
passing buses or large trucks. Frequently check behind when moving
alongside such vehicles. As soon as such vehicle movement occurs,
immediately start to decelerate smoothly by slowly applying the
brakes. Always steer the vehicle straight ahead while braking.
■Passing other vehicles
Consider the total combined length of your vehicle and trailer and
ensure that the vehicle-to-vehicle distance is sufficient before execut-
ing lane changes.
■Transmission information
Refrain from driving in 6 range in S mode to maintain the effectiveness
of the engine brake and the charge performance of electrical compo-
nents.
■If the engine overheats
Towing a loaded trailer up a long, steep incline in temperatures
exceeding 30°C (85°F) may result in the engine overheating. If the
engine coolant temperature gauge indicates that the engine is over-
heating, turn the air conditioning off immediately, leave the road and
stop the vehicle in a safe place. (→P. 5 9 8 )
■When parking the vehicle
Always place wheel chocks under the wheels of both the vehicle and
trailer. Firmly set the parking brake and shift the shift lever to P.
