Selecting tire chains
Tire chains can be mounted on 16- and 17-inch tires. They cannot
be mounted on 18-inch tires. Use the correct tire chain size when
mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(3 mm [0.12 in.] in diameter)
Cross chain
(4 mm [0.16 in.] in diameter)
Regulations on the use of tire chains
Regulations regarding the use of tire chains vary according to
location and type of road. Always check local regulations before
installing chains.
Install the chains on the rear tires.
When driving the vehicle
Accelerate the vehicle slowly and drive at a reduced speed
suitable to road conditions.
When parking the vehicle
Park the vehicle and move the shift lever to P (automatic
transmission) or 1 or R (manual transmission) without setting
the parking brake. The parking brake may freeze up, prevent-
ing it from being released. If necessary, block the wheels to
prevent inadvertent sliding or creeping.

When driving
IS250/220d/200d_EEImportant points regarding turning
The wheels of the trailer will travel closer to the inside of the
curve than the wheels of the vehicle. To make allowance for this,
take the turns wider than you would normally.
Important points regarding stability
Vehicle movement resulting from uneven road surfaces and
strong crosswinds will affect handling. The vehicle may also be
rocked by passing buses or large trucks. Frequently check
behind when moving alongside such vehicles. As soon as such
vehicle movement occurs, immediately start to decelerate
smoothly by slowly applying the brakes. Always steer the vehi-
cle straight ahead while braking.
Passing other vehicles
Consider the total combined length of your vehicle and trailer
and ensure that the vehicle-to-vehicle distance is sufficient
before executing lane changes.
Transmission information
Refrain from driving in 6 (manual transmission) or 4 range in S
mode (automatic transmission) to maintain the effectiveness of
the engine brake and the charge performance of electrical com-
ponents.
If the engine overheats...
Towing a loaded trailer up a long steep incline in temperatures
exceeding 30C (85F) may result in the engine overheating. If
the engine coolant 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. (P. 525)
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 for automatic transmissions, and 1 or R for manual trans-
missions.

CAUTION
Observe the following precautions.
Failure to do so may cause the driver's floor mat to slip, possibly interfering
with the pedals while driving. An unexpectedly high speed may result or it
may become difficult to stop the vehicle, leading to a serious accident.
When installing the driver's floor mat
Do not use floor mats designed for other models or different model year
vehicles, even if they are Lexus Genuine floor mats.
Only use floor mats designed for the driver's seat.
Always install the floor mat securely using the retaining hooks (clips) pro-
vided.
Do not use two or more floor mats on top of each other.
Do not place the floor mat bottom-side up or upside-down.
Before driving
Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this check
after cleaning the floor.
With the engine stopped and the shift
lever in P (automatic transmission) or
N (manual transmission), fully depress
each pedal to the floor to make sure it
does not interfere with the floor mat.
