CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
■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 eyelet and the cable or chain. Always be cautious of the
surroundings and other vehicles while towing.
●Gasoline vehicles: If the engine is not running, the power assist for the brakes and
steering will not function, making steering and braking more difficult.
Hybrid vehicles: 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 eyelet to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelet may come loose during towing.
NOTICE
■To prevent causing serious damage to the transmission when towing using a
wheel-lift type truck
Never tow this vehicle from the rear with the front wheels on the ground. This may
cause serious damage to the transmission.
■To prevent damage to the vehicle when towing using a wheel-lift type truck
When raising the vehicle, ensure adequate ground clearance for towing at the
opposite end of the raised vehicle. Without adequate clearance, the vehicle could
be damaged while being towed.
■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.

■Front passenger detection sensor, seat belt reminder and warning buzzer
●If luggage is placed on the front passenger seat, the front passenger detection sen-
sor may cause the warning light to flash and the warning buzzer to sound even if a
passenger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.
■If the malfunction indicator lamp comes on while driving
First check the following:
●Is the fuel tank empty?
If it is, fill the fuel tank immediately.
●Is the fuel tank cap loose?
If it is, tighten it securely.
The light will go off after several driving trips.
If the light does not go off even after several trips, contact your Lexus dealer as soon
as possible.
■When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch will not turn off the tire pressure warning light.

■Ceintures de sécurité
Avec un chiffon ou une éponge, nettoyez à l’aide d’un savon doux et de
l’eau tiède. Vérifiez aussi les ceintures régulièrement pour vous assurer
qu’elles ne présentent pas d’usure excessive, d’effilochage ou de cou-
pures.
Entretien et soin
ATTENTION
■Dommages et usure de la ceinture de sécurité
Vérifiez périodiquement le système de ceintures de sécurité. Assurez-vous qu’il
n’y a pas de coupures, d’effilochures ni de pièces desserrées. N’utilisez pas une
ceinture de sécurité endommagée avant qu’elle ne soit remplacée. Les ceintures
de sécurité endommagées ne peuvent pas protéger les occupants contre les bles-
sures graves, voire mortelles.
