Maintenance and care 5
When trouble arises

381-1. Hybrid system
CAUTION●
If your vehicle needs to be towed, do so with all front wheels (for 2WD models) or
four wheels (for AWD models) raised. If the wheels connected to the electric
motor (traction motor) are on the ground when towing, the motor may continue
to generate electricity. This may cause an electricity leakage leading to a fire.
(
 P. 7 2 5 )●
Carefully inspect the ground under the vehicle. If you find that liquid has leaked
onto the ground, the fuel system may have been damaged. Leave the vehicle as
soon as possible.■
Nickel-metal hydride battery
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improp-
erly, it is hazardous to the environment and there is a risk of severe burns and elec-
trical shock that may result in death or serious injury.■
Emergency shut off system
Carefully check to see if there are exposed high voltage parts or cables. Never
touch the parts or cables. (
 P. 3 4 )
NOTICE■
Hybrid battery air vents ●
Do not put foreign objects over the air vents. The hybrid battery (traction battery)
may overheat or lose power and be damaged. ●
Clean the air vents regularly to prevent the hybrid battery (traction battery) from
overheating.●
Do not wet or allow foreign substances to enter the air vents as this may cause a
short circuit and damage the hybrid battery (traction battery).●
Do not carry large amounts of water such as an aquarium into the vehicle. If water
spills onto the hybrid battery (tractio n battery), the battery may be damaged.
Have the vehicle inspected by your Lexus dealer.
