■

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.

■

Trailer Sway Control precaution

The Trailer Sway Control system is not

able to reduce trailer sway in all situa-

tions. Depending on many factors such

as the conditions of the vehicle, trailer,

road surface and driving environment,

the Trailer Sway Control system may not

be effective. Refer to your trailer owner’s

manual for information on how to tow

your trailer properly.

■



Park the vehicle and move the shift
lever to P without setting the park-
ing brake. The parking brake may
freeze up, preventing it from being
released. If the vehicle is parked
without setting the parking brake,
make sure to block the wheels.
Failure to do so may be dangerous
because it may cause the vehicle to

move unexpectedly, possibly lead-
ing to an accident.

When the parking brake is in automatic
mode, release the parking brake after shift-
ing the shift lever to P. (



P.171)



If the vehicle is left parked with the
brakes damp in cold temperatures,
there is a possibility of the brakes
freezing.



If the vehicle is parked without set-
ting the parking brake, confirm that
the shift lever cannot be moved out
of P

: The shift lever will be locked if it is

attempted to be shifted from P to any
other position without depressing the
brake pedal. If the shift lever can be
shifted from P, there may be a problem
with the shift lock system. Have the vehi-
cle inspected by your Lexus dealer
immediately.

Use the correct tire chain size when
mounting the tire chains. Chain size is
regulated for each tire size.
