Tire information
Increase the tire inflation pressure to 20.0 kPa (0.2 kgf/cm2 or bar, 3 psi) greater
than the recommended value when towing. (P. 570)
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.
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 pro-
vide 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 nor-
mal driving.
Retighten all bolts securing the hitching ball and bracket after towing for
approximately 1000 km (600 miles).
NOTICE
When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that area.
When steel and aluminum come into contact, there is a reaction similar to cor-
rosion, which will weaken the section concerned and may result in damage.
Apply a rust inhibitor to parts that will come in contact when attaching a steel
bracket.

Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily
canceled. The functions will resume after the necessary operating conditions
have returned.
The turn signal lever is operated.
The vehicle speed deviates from the operating range of the LDA system func-
tions.
When the lane lines cannot be recognized while driving.
When the lane departure warning sounds.
The lane departure warning function will not operate again for a several sec-
onds after it has been activated, even if the vehicle leaves the lane again.
The lane departure warning
Depending on the audio system sound level or air conditioning fan noise while
the audio system or air conditioning system is in use, it may be difficult to hear
the warning sound.
After the vehicle has been parked in the sun
The LDA system may not be available and a warning message (P. 518) will be
displayed for a while after driving has started. When the temperature in the cabin
decreases and the temperature around the camera sensor (P. 264) becomes suit-
able for its operation, the functions will begin to operate.
If there are lane markers on only one side of the vehicle
The lane departure warning will not operate for the side on which lane markers
could not be recognized.
Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize lane
markers causing the lane departure warning function to operate incorrectly. How-
ever, this does not indicate a malfunction.
When driving through an area with no lane markers, such as a tollbooth, a
crossing or before a ticket checkpoint
When driving on a sharp curve
When lane markers are extremely narrow or extremely wide
When the vehicle leans to one side an unusual amount due to a heavy load or
improper tire inflation pressure
When the following distance between your vehicle and the vehicle ahead is
extremely short
When the lane markers are yellow (These may be more difficult for the system
to recognize compared to white markers.)
When the lane markers are broken, Botts’ dots (raised pavement markers) or
stones
When the lane markers are on a curb etc.
When lane markers are obscured or partially obscured by sand, dirt, etc.
When there are shadows on the road running parallel with lane markers, or if a
shadow covers the lane markers
When driving on a particularly bright road surface, such as concrete

CAUTION
The ABS does not operate effectively when
The limits of tire gripping performance have been exceeded (such as exces-
sively worn tires on a snow covered road).
The vehicle hydroplanes while driving at high speed on wet or slick roads.
Stopping distance when the ABS is operating may exceed that of normal condi-
tions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the fol-
lowing situations:
When driving on dirt, gravel or snow-covered roads
When driving with tire chains
When driving over bumps in the road
When driving over roads with potholes or uneven surfaces
TRC may not operate effectively when
Directional control and power may not be achievable while driving on slippery
road surfaces, even if the TRC system is operating.
Drive the vehicle carefully in conditions where stability and power may be lost.
Hill- start assist control does not operate effectively when
Do not overly rely on hill-start assist control. Hill-start assist control may not
operate effectively on steep inclines and roads covered with ice.
Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use hill-
start assist control to hold the vehicle on an incline, as doing so may lead to an
accident.
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. 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 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 specified size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the recom-
mended tire inflation pressure level.
The ABS, TRC 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 the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Air conditioning
Use the air conditioning only when necessary. Doing so can help
reduce excessive gasoline consumption.
In summer: When the ambient temperature is high, use the recirculated
air mode. Doing so will help to reduce the burden on the air condition-
ing system and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut out
until it and the interior of the vehicle are warm, it will consume fuel.
Fuel consumption can be improved by avoiding overuse of the heater.
Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently. Improper tire
inflation pressure can cause poor fuel economy.
Also, as snow tires can cause large amounts of friction, their use on dry
roads can lead to poor fuel economy. Use tires that are appropriate for
the season.
Luggage
Carrying heavy luggage can lead to poor fuel economy. Avoid carrying
unnecessary luggage. Installing a large roof rack can also cause poor
fuel economy.
Warming up before driving
Since the gasoline engine starts up and cuts out automatically when
cold, warming up the engine is unnecessary. Moreover, frequently
driving short distances will cause the engine to repeatedly warm up,
which can lead to excess fuel consumption.

CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or seri-
ous injury.
Use tires of the specified size.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit specified
for the snow tires being used.
Use snow tires on all, not just some wheels.
Driving with tire chains (except vehicles with 18-inch tires)
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely, and
may cause death or serious injury.
Do not drive in excess of the speed limit specified for the tire chains being
used, or 50 km/h (30 mph), whichever is lower.
Avoid driving on bumpy road surfaces or over potholes.
Avoid sudden acceleration, abrupt steering, sudden braking and shifting oper-
ations that cause sudden engine braking.
Slow down sufficiently before entering a curve to ensure that vehicle control
is maintained.
Do not use LDA (Lane Departure Alert) system.
NOTICE
Repairing or replacing snow tires
Request repairs or replacement of snow tires from Lexus dealers or legitimate
tire retailers.
This is because the removal and attachment of snow tires affects the operation
of the tire pressure warning valves and transmitters.
Fitting tire chains (except vehicles with 18-inch tires)
The tire pressure warning valves and transmitters may not function correctly
when tire chains are fitted.
