Driving
or move a wiper that is frozen. Pour
warm water over the frozen area to
melt the ice. Wipe away the water
immediately to prevent it from
freezing.
 To ensure proper operation of the
climate control system fan, remove
any snow that has accumulated on
the air inlet vents in front of the
windshield.
 Check for and remove any excess
ice or snow that may have accumu-
lated on the exterior lights, vehicle’s
roof, chassis, around the tires or on
the brakes.
 Remove any snow or mud from the
bottom of your shoes before getting
in the vehicle.
Accelerate the vehicle slowly, keep a
safe distance between you and the
vehicle ahead, and drive at a reduced
speed suitable to road conditions.
 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.140)
 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 with out depressing the
brake pedal. If the shift lever can be
shifted from P, ther e may be a problem
with the shift lock sy stem. Have the vehi-
cle inspected by your Lexus dealer
immediately.

 Wipe away any water.
 Wax the vehicle when the water-
proof coating deteriorates.
If water does not bead on a clean surface,

■Black stainless steel window moldings
(IS500)
The stainless steel window moldings are
made of black oxide coated stainless steel.
When cleaning the vehicle, do not scrub the

ing that is resistant to small surface
scratches caused in a car wash etc.
●The coating lasts for 5 to 8 years from
when the vehicle is delivered from the

●The restoration time differs depending on
the depth of the scratch and outside tem-
perature.
The restoration time may become
shorter when the coating is warmed by
applying warm water.

etc. cannot be restored.
