5-2. Steps to take in an emergency
If the retractable hardtop does not close
Unlock the trunk. (P. 5 1 )
Open the trunk fully.
If the retractable hardtop does not clos e when the switch is pressed, check
that all operating conditions are met. ( P. 9 1 )
If the retractable hardtop will not cl ose even though all operating condi-
tions have been met, there may be a malfunction. Immediately have the
vehicle inspected by your Lexus dealer.
As a temporary measure, the following procedure can be performed to
manually close the retractable hardtop.
■ Notes for manually closing the retractable hardtop
●This procedure requires 2 people.
● There is some risk of damage to the vehicle during the procedure,
such as when applying consi derable force or removing and
installing various parts. If you are unsure of how to perform this
procedure properly, it is recommended that you contact your
Lexus dealer.
● Protect your hands with gloves etc. when placing them in narrow
spaces.
● Before starting the procedure, turn the “ENGINE START STOP”
switch off.

■When manually closing the retractable hardtop
Observe the following precautions:
●Stop the vehicle on a flat surface in a safe place.
●Set the parking brake and shift the shift lever to P.
●Ensure that there are no occupants inside the vehicle.
●Do not perform this procedure while there are strong winds blowing.
●Turn the “ENGINE START STOP” switch off.
●Be careful not to catch any part of your body or clothing in the moving parts.
●Some parts of this procedure may result in an injury if performed with bare hands.
Protect your hands with gloves or a piece of cloth when performing the proce-
dure.
NOTICE

5-2. Steps to take in an emergency
If your vehicle has to be stopped in an emergency
CAUTION
■If the engine has to be turned off while driving
Power assist for the brakes and steering wheel will be lost, making the brake pedal
harder to depress and the steering wheel heavier to turn. Decelerate as much as
possible before turning off the engine.
Only in an emergency, such as if it becomes impossible to stop the vehicle
in the normal way, stop the vehicle using the following procedure:
Steadily step on the brake pe dal with both feet and firmly
depress it.
Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N After slowing down, stop the vehicl e in a safe place by the road.
Stop the engine.
If the shift lever cannot be shifted to N Keep depressing the brake pedal with both feet to reduce vehi-
cle speed as much as possible.
Stop the engine by pressing and
holding the “ENGINE START
STOP” switch for 3 consecutive
seconds or more.
Stop the vehicle in a safe place by the road.

Vehicle identification■ Vehicle identification number
The vehicle identification number (V IN) is the legal identifier for your
vehicle. This is the primary identification number for your Lexus. It is used
in registering the ownership of your vehicle.
This number is stamped on the top left of the instrument panel and in the
engine compartment.
This number is also on the Certifi-
cation Label.

■ Engine oil selection
IS250C
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced with
SAE 0W-20 at the next oil
change.

Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows coldstartability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscos ity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubrican t Standardization and Approval
Committee) Certification Mark is added to some oil containers to help
you select the oil you should use.

“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the follow-
ing grade and viscosity.
Oil grade: ILSAC multigrade engine oil
Recommended viscosity: SAE 5W-30
SAE 5W-30 is the best choice for
good fuel economy and good
starting in cold weather.
If SAE 5W-30 is not available,
SAE 10W-30 oil may be used.
However, it should be replaced
with SAE 5W-30 at the next oil
change.
Oil viscosity (5W-30 is explained here as an example):
• The 5W in 5W-30 indicates the characteristic of the oil which allows coldstartability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 30 in 5W-30 indicates the viscos ity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
