■Before towing
●Ensure that your vehicle’s tires are properly inflated. (→P. 3 3 4 )
●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_(L/O_0808)●
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”. ( →P. 4 1 6 )

2-5. Driving information
ES350_U_(L/O_0808)●
Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking 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 place, 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 the R position (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks.
Stop and apply the brakes.
Have someone retrieve the blocks.
CAUTION
■To avoid an accident
●Do not exceed 45 mph (72 km/h) or posted towing speed limit, whichever is
lower. As instability (swaying) of the towing vehicle-trailer combination increases
as speed increases, exceeding 45 mph (72 km/h) may cause loss of control.
●Slow down and downshift before descending steep or long downhill grades. Do
not make sudden downshifts.
●Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat and result in reduced braking efficiency.
