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.

621-3. Opening, closing and locking the doors

Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication betw een the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start, wire-
less remote control and immobilize r system from operating properly.
(Ways of coping:  P. 7 8 1 )●
When the electronic key battery is depleted●
Near a TV tower, electric power plant, gas station, radio st ation, large display,
airport or other facility that generates strong radio waves or electrical noise●
When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication devices●
When the electronic key is in contact wi th, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs●
When multiple electronic keys are in the vicinity●
When another wireless key (that emits radio waves) is being used nearby●
When carrying the electronic key togeth er with the following devices that emit
radio waves
• Another vehicle's electronic key or a wireless key that emits radio waves
• Personal computers or person al digital assistants (PDAs)
• Digital audio players
• Portable game systems●
If window tint with a metallic content or metallic objects are attached to the rear
window

1401-8. Safety information
CAUTION■
SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury. ●
The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.●
The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many dr ivers can achieve the 10 in. (250 mm)
distance, even with the driver seat all the way forward, simply by reclining the
back of the seat somewhat. If reclining the back of your seat makes it hard to
see the road, raise yourself by using a firm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, ti lt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still main-
taining control of the foot pedals, steering wheel, and your view of the instrument
panel controls.
