CAUTION
■If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS airbag warning lights not
come on when you start the engine, this could mean that these systems are not
available to help protect you in an accident, which could result in death or serious
injury. Have the vehicle inspected by your Lexus dealer immediately if this occurs.
■Warning lights
Warning lights inform the driver of malfunctions or suspected prob-
lem in any of the vehicle’s systems. ( oP. 4 3 9 )
*: These lights turn on when the “ENGINE START STOP” switch is turned
to IGNITION ON mode to indicate that a system check is being per-
formed. They will turn off after the engine is started, or after a few sec-
onds. There may be a malfunction in a system if a light does not come on,
or if the lights do not turn off. Have the vehicle inspected by your Lexus
dealer.

■The windshield wiper and washer can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■Rain drop sensor
●If the temperature of the raindrop sensor is 194qF (90 qC) or higher, or 5 qF
( -1 5 qC) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO”,
■AUTO mode
If the wiper switch is turned to AUTO position while the “ENGINE START STOP”
switch is in IGNITION ON mode, the wiper will operate once to show that AUTO
mode is activated.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
Wash/wipe operation
Wipers operate automatically.
(With “AUTO” selected, after
operating several times, the wip-

a short delay to prevent drip-
ping.)
●The sensor judges the amount of raindrops.

■Before towing
●Ensure that your vehicle’s tires are properly inflated. (oP. 396)
●Trailer tires should be inflated according to the trailer manufacturer's recom-
mendation.
●All trailer lights work to be legal.
●Confirm all lights work each time you connect them.
●Check that your vehicle remains level when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle is not level, and check for improper tongue
load, overloading, worn suspension, or other possible causes.
●Make sure the trailer cargo is securely loaded.
●Check that your rear view mirrors conform to any federal, state/provincial or
local regulations. If they do not, install rear view mirrors appropriate for towing
purposes.
■Break-in schedule
Lexus recommends that you do not use a new vehicle or a vehicle with any new
power train components (engine, transmission, differential, wheel bearings, etc.) to
tow a trailer for the first 500 miles (800 km) of driving.
■Maintenance
●If you tow a trailer, your vehicle will require more frequent maintenance due to
the additional load. (See “Warranty and Services Guide/Owner's Manual Sup-
plement/ Scheduled Maintenance”.)
●Retighten the fixing bolts of the towing ball and bracket after approximately
600 miles (1000 km) of trailer towing.
CAUTION
■To avoid accident or injury
●The total trailer weight (trailer weight plus the weight of cargo) must not exceed
1000 lb. (450 kg).
●Do not exceed the trailer hitch assembly weight, gross vehicle weight, gross axle
weight and trailer tongue load capacities.
●Never load more weight in the back than in the front of the trailer. About 60% of
the load should be in the front half of the trailer, and the remaining 40% in the
r e a r.

When driving
ES350_U●
Avoid sudden braking as you may skid, resulting in jackknifing and loss
of control. This is especially true on wet or slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making a
turn.
● Note that when making a turn, the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. Compensate by making a
larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway. Periodically check the rear to prepare
for being passed by large trucks or buses, which may cause your vehi-
cle and trailer to sway. If swaying occurs, firmly grip the steering wheel,
reduce speed immediately but gradually, and steer straight ahead.
Never increase speed. If you make no extreme correction with the
steering or brakes, your vehicle and trailer will stabilize.
● Take care when passing other vehicles. Passing requires considerable
distance. After passing a vehicle, do not forget the length of your
trailer, and be sure you have plenty of room before changing lanes.
● In order to maintain efficient engine braking and electrical charging
performance, do not use overdrive. Transmission shift range position
must be in 4, in the S mode.
● Due to the added load of the trailer, your vehicle's engine may over-
heat on hot days (at temperatures over 85°F [30°C]) when driving up
a long or steep grade. If the engine coolant temperature gauge indi-
cates overheating, immediately turn off the air conditioning (if in use),
pull your vehicle off the road and stop in a safe spot. See “If you vehicle
overheats”. ( oP. 480)
