Radiator and condenser
Check the radiator and condenser and clear away any foreign
objects.
If either of the above parts is extremely dirty or you are not sure of
their condition, have your vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped
professional.
CAUTION
When the hybrid system is hot
Do not touch the radiator or condenser as they may be hot and cause serious
injuries, such as burns.
When the electric cooling fans are operating
Do not touch the engine compartment.
The electric cooling fans may keep rotating for about 3 minutes even after
the “POWER” switch is off.
With the “POWER” switch in ON mode, the electric cooling fans may auto-
matically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. Be sure the “POWER” switch is off when working near the
electric cooling fans or radiator grille.

Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
If recharging with the 12-volt battery installed on the vehicle, be sure to
disconnect the ground cable.
Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the 12-volt battery.
After recharging/reconnecting the 12-volt battery
Unlocking the doors using the smart entry & start system may not be
possible immediately after reconnecting the 12-volt battery. If this hap-
pens, use the wireless remote control or the mechanical key to lock/
unlock the doors.
Start the hybrid system with the “POWER” switch in ACCESSORY
mode. The hybrid system may not start with the “POWER” switch
turned OFF. However, the hybrid system will operate normally from the
second attempt.
The “POWER” switch mode is recorded by the vehicle. If the battery is
reconnected, the vehicle will return the “POWER” switch mode to the
status it was in before the battery was disconnected. Make sure to turn
off the power before disconnect the battery. Take extra care when con-
necting the battery if the “POWER” switch mode prior to discharge is
unknown.
Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.

After a fuse is replaced
If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (P. 534)
If the replaced fuse blows again, have the vehicle inspected by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
When replacing light bulbs
Lexus recommends that you use genuine Lexus products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.

CAUTION
Caution while towing
Use extreme caution when towing the vehicle.
Avoid sudden starts or erratic driving maneuvers which place excessive
stress on the emergency towing eyelets and the cables or chains. Always
be cautious of the surroundings and other vehicles while towing.
Do not turn the “POWER” switch off.
This may lead to an accident as the front wheels will be locked by the
parking lock.
If the hybrid system is off, the power assist for the brakes and steering will
not function, making steering and braking more difficult.
Installing towing eyelets to the vehicle
Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing. This
may lead to accidents that cause serious injury or even death.
NOTICE
To prevent damaging the vehicle
When raising the vehicle, ensure adequate ground clearance for towing at
the opposite end of the raised vehicle. Without adequate clearance, the vehi-
cle could be damaged while being towed.
To prevent causing serious damage to the hybrid transmission when towing
using a wheel-lift type truck
Never tow this vehicle from the front with the rear wheels on the ground.
To prevent body damage when towing with a sling-type truck
Do not tow with a sling-type truck, either from the front or rear.
To prevent causing serious damage to the hybrid transmission in emergency
towing
Never tow a vehicle from the rear with four wheels on the ground. This may
cause serious damage to the hybrid transmission.
