■
■Washing the vehicle
To prevent paint deterioration and corrosion on the body and components (wheels
etc.), wash the vehicle immediately if it becomes dirty. Hand washing is recommended
to preserve the paint finish.
1 Working from top to bottom, liberally apply water to the vehicle body, wheel wells
and underside of the vehicle to remove any dirt and dust.
2 Wash the vehicle body using a sponge or soft cloth, such as a chamois.
3 For hard-to-remove marks, use a neutral detergent and rinse thoroughly with
water.
4 Wipe away any water.
Maintaining the vehicle’s exterior

92
Refer to the following points in order to preserve the performance and appearance
of the LFA during long-term storage. These points are only guidelines. To ensure that
appropriate steps are taken in consideration of the storage duration and environment,
consult your Lexus dealer in advance.
■
■Storage environment
A dry, covered, flat location away from natural elements such as wind, rain and direct
sunlight is ideal.
Exposure to the elements can cause corrosion and scratches, while long-term
exposure to direct sunlight can cause the interior and exterior finish to fade or become
discolored. Additionally, as moisture from the ground may cause corrosion even if the
vehicle is stored in a covered location, a dry place is ideal.
■
■Cleaning
As dirt becomes harder to remove with time, both the vehicle’s interior and exterior
should be cleaned before the vehicle is put into long-term storage.
■
■Tires
Inflate the tires to approximately 44 psi (300 kPa, 3.0 kgf/cm2 or,bar,) and use wheel
chocks to prevent the vehicle from moving.
In order to help reduce flat spots from occurring during storage, regularly rotate the
tires so that the same point is n’ot always resting on the ground. Additionally, if the
tires develop flat spots during the storage interval, drive the vehicle slowly until any flat
spot-induced vibrations are no longer felt before resuming normal use.
■
■Parking brake
Use wheel chocks to prevent the vehicle from moving as it should be stored with the
parking brake disengaged.

Use a flatbed truck suitable for vehicles with low ground clearance. To prevent body
damage, do not tow with a wheel-lift or sling type truck. We recommend having your
Lexus dealer or a commercial towing service load and unload the vehicle whenever
possible.
Please refer to the following dimensions when choosing an appropriate tow/transport
vehicle.
