4-1. Before driving
cle straight ahead while braking.
Q Passing other vehicles
Consider the total combined length of
your vehicle and trailer and ensure that
the vehicle-to-vehicle distance is suffi-
cient before executing lane changes.
Q Transmission information
To maintain engine braking efficiency,
when using engine braking, do not use
the transmission in D.
If in the M mode, the transmission shift
range position must be in 7 or lower.
(oP.236)
Q If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures exceed-
ing 30°C (85°F) may result in the
engine overheating. If the engine cool-
ant temperature gauge indicates that
the engine is overheating, turn the air
conditioning off immediately, leave the
road and stop the vehicle in a safe
place. (oP.616)
Q 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.
Q 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).
Q If trailer sway occurs
One or more factors (crosswinds, passing
vehicles, rough roads, etc.) can adversely
affect handling of your vehicle and trailer,
causing instability.
O If trailer swaying occurs:
• Firmly grip the steering wheel. Steer
straight ahead.
Do not try to control trailer swaying by
turning the steering wheel.
• Begin releasing the accelerator pedal
immediately but very gradually to reduce
speed.
Do not increase speed. Do not apply
vehicle brakes.
If you make no extreme correction with the
steering or brakes, your vehicle and trailer
should stabilize (if enabled, Trailer Sway
Control can also help to stabilize the vehi-
cle and trailer.).
O After the trailer swaying has stopped:
• Stop in a safe place. Get all occupants
out of the vehicle.
• Check the tires of the vehicle and the
trailer.
• Check the load in the trailer.
Make sure the load has not shifted.
Make sure the tongue weight is appropri-
ate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not overloaded
after occupants get in.
If you cannot find any problems, the speed
at which trailer swaying occurred is beyond
the limit of your particular vehicle-trailer
combination. Drive at a lower speed to pre-
vent instability. Remember that swaying of
the towing vehicle-trailer increases as
speed increases.
