cle is reversing, adjust the mirror angle at a
desired position with the shift position in R.
The adjusted angle will be memorized and
the mirror will automatically tilt to the mem-
orized angle whenever the shift position is
shifted to R from next time.
The memorized downward tilt position of
the mirror is linked to the normal position
(angle adjusted with the shift position in

and the road surface, preventing the
steering and brakes from operating prop-
erly.

Driving procedure

162 4-1. Before driving
LS500h_OM_OM50F42U_(U) WARNING■
When the vehicle is parked●
Do not leave glasses, cigarette lighters,
spray cans, or soft drink cans in the
vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter
or spray can, and may lead to a fire.
• The temperature inside the vehicle
may cause the plastic lenses and plas-
tic material of glasses to deform or
crack.
• Soft drink cans may fracture, causing
the contents to spray over the interior
of the vehicle, and may also cause a
short circuit in the vehicle’s electrical
components.●
Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a
place such as the glove box or on the
floor, it may be lit accidentally when
luggage is loaded or the seat is
adjusted, causing a fire.●
Do not attach adhesive discs to the
windshield or windows. Do not place
containers such as air fresheners on
the instrument pane l or dashboard.
Adhesive discs or containers may act
as lenses, causing a fire in the vehicle.
●
Do not leave a door or window open if
the curved glass is coated with a met-
allized film such as a silver-colored
one. Reflected sunlight may cause the
glass to act as a lens, causing a fire.
●
Always apply the parking brake, shift
the shift position to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended
while the “READY” indicator is illumi-
nated.
●
Do not touch the exhaust pipes while
the “READY” indicator is illuminated
or immediately after turning the hybrid
system off.
Doing so may cause burns. ■
When taking a nap in the vehicle
Always turn the hybrid system off. Other-
wise, if you accident ally move the shift
lever or depress the accelerator pedal,
this could cause an accident or fire due
to hybrid system overheating. Addition-
ally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may col-
lect and enter the vehicle, leading to
death or a serious health hazard. ■
When braking ●
When the brakes are wet, drive more
cautiously.
Braking distance in creases when the
brakes are wet, and this may cause one
side of the vehicle to brake differently
than the other side. Also, the parking
brake may not securely hold the vehi-
cle. ●
If the electronically controlled brake
system does not operate, do not follow
other vehicles closely and avoid hills or
sharp turns that require braking.
In this case, braking is still possible, but
the brake pedal should be depressed
more firmly than usual. Also, the brak-
ing distance will in crease. Have your
brakes fixed immediately. ●
The brake system consists of 2 or more
individual hydraulic systems; if one of
the systems fails, the other(s) will still
operate. In this case, the brake pedal
should be depressed more firmly than
usual and the braking distance will
increase. Have your brakes fixed
immediately.
■
If the vehicle becomes stuck
Do not spin the wheels excessively when
a driven wheel is up in the air, or the vehi-
cle is stuck in sand, mud, etc. This may
damage the driveline components or
propel the vehicle forward or backward,
causing an accident.
