Hill-start assist control
■Hill-start assist control can be operated when
●The shift lever is in a position other than P.
●The parking brake is not applied.
●The accelerator pedal is not depressed.
■Hill-start assist control
●While hill-start assist control is operating, the brakes remain automatically
applied after the driver releases the brake pedal. The stop lights and the high
mounted stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal is
released.
●If the slip indicator does not flash and the buzzer does not sound when the brake
pedal is further depressed, slightly reduce the pressure on the brake pedal (do
not allow the vehicle to roll backward) and then firmly depress it again. If the sys-
tem still does not operate, check if the operating conditions explained above
have been met.
Hill-start assist control helps to prevent the vehicle from rolling backwards
when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is activated.
The slip indicator will also start
flashing.

■Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
●On roads with sharp bends or uneven surfaces
●If a vehicle suddenly moves in front of your vehicle, such as at an intersection
●If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●In inclement weather such as heavy rain, fog, snow or sand storms
●When your vehicle is skidding with the VSC system off
●When an extreme change in vehicle height occurs
●When the axis of the radar is out of adjustment
■Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-crash safety system will be auto-
matically disabled. In this case, the system will not activate even if there is a collision
possibility.
■When there is a malfunction in the system, or if the system is temporarily unus-
able
Warning lights and/or warning messages will turn on or flash. (→P. 5 4 3 , 5 5 2 )

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.

■Tire info rmat ion
●Ensure that your vehicle’s tires are properly inflated. Adjust the tire pressure to
the recommended pressure. (→P. 6 1 7 )
●Increase the air pressure of the trailer tires in accordance with the total trailer
weight and according to the values recommended by the manufacturer of your
trailer.
■Trailer lights
●Check that the turn signal lights and stoplights are operating correctly every
time you hitch up the trailer. Directly wiring up to your vehicle may damage the
electrical system and stop the lights from functioning correctly.
●Please consult at any authorized dealer or repairer, or another duly qualified
and equipped professional when installing trailer lights, as incorrect installation
may cause damage to the vehicle’s lights. Please take care to comply with your
state’s laws when installing trailer lights.
■Break-in schedule
Lexus recommends that vehicles fitted with new power train components should
not be used for towing trailers for the first 800 km (500 miles).
■Safety checks before towing
●Check that the maximum load limit for the towing hitch/bracket hitch ball is not
exceeded. Bear in mind that the coupling weight of the trailer will add to the
load exerted on the vehicle. Also make sure that you will not be towing a load
that exceeds the maximum permissible axle capacity.
●Ensure that the trailer load is secure.
●Supplementary outside rear view mirrors should be added to the vehicle if the
traffic behind cannot be clearly seen with standard mirrors. Adjust the extend-
ing arms of these mirrors on both sides of the vehicle so that they always provide
maximum visibility of the road behind.
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight burden placed on the vehicle compared to
normal driving.
●Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).

When driving
RX350/270_EE
Guidance
Your vehicle will handle differently when towing a trailer. In order to avoid
accident, death or serious injury, keep the following in mind when towing:
■Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection between
the trailer and lights after driving for a brief period as well as before
starting off.
■Practicing driving with a coupled trailer
●Get the feel for turning, stopping and reversing with the trailer cou-
pled by practicing in an area with no or light traffic.
●When reversing with a coupled trailer, hold the section of the steer-
ing wheel nearest to you and rotate clockwise to turn the trailer left
or counterclockwise to turn it right. Always rotate a little at a time to
prevent steering error. Have someone guide you when reversing to
lessen the risk of an accident.
■Increasing vehicle-to-vehicle distance
At a speed of 10 km/h (6 mph), the distance to the vehicle running
ahead of you should be equivalent to or greater than the combined
length of your vehicle and trailer. Avoid sudden braking that may cause
skidding. Otherwise, the vehicle may spin out of control. This is espe-
cially true when driving on wet or slippery road surfaces.
■Sudden acceleration/steering input/cornering
Executing sharp turns when towing may result in the trailer colliding
with your vehicle. Decelerate well in advance when approaching turns
and take them slowly and carefully to avoid sudden braking.
