Before driving
IS F_EE
CAUTION
Child restraint precautions
Never use a rear-facing child restraint system on the front passenger seat
when the airbag manual on-off switch is on. (P. 135)
In the event of an accident, the force of the rapid inflation of the front pas-
senger airbag can cause death or serious injury to the child.
A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. Always move the seat as far back
as possible, because the front passenger airbag could inflate with consid-
erable speed and force. Otherwise, the child may be killed or seriously
injured.
Do not allow the child to lean his/her head or any part of his/her body
against the door or the area of the seat, front pillar, rear pillar or roof side
rail from which the side airbags or curtain shield airbags deploy even if
the child is seated in the child restraint system. It is dangerous if the side
airbags and curtain shield airbags inflate, and the impact could cause
death or serious injury to the child.
Make sure you have complied with all installation instructions provided
by the child restraint manufacturer and that the system is properly
secured. If it is not secured properly, it may cause death or serious injury
to the child in the event of a sudden stop, sudden swerve or an accident.
When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
When the child restraint system is not in use
Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the restraint unsecured in the passenger compart-
ment.
If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the trunk. This will prevent it from injuring
passengers in the event of a sudden stop, sudden swerve or an accident.

If your vehicle needs to be towed
Before towing
The following may indicate a problem with your transmission.
Contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional, before towing.
The engine is running, but the vehicle will not move.
The vehicle makes an abnormal sound.
Emergency towing
If a tow truck is not available, in an emergency your vehicle may
be temporarily towed using a cable or chain secured to the emer-
gency towing eyelet. This should only be attempted on hard, sur-
faced roads for short distances at low speeds.
A driver must be in the vehicle to steer and operate the brakes. The
vehicle’s wheels, drive train, axles, steering and brakes must be in
good condition.
If towing is necessary, we recommend having your vehicle towed by
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, such as a commercial towing service, using a
lift-type truck or a flat bed truck.
Use a safety chain system for all towing, and abide by all state/provin-
cial and local laws.
If towing from the rear, the vehicle's front wheels and axles must be in
good condition. (P. 421)
If they are damaged, use a towing dolly or flat bed truck.

5-2. Steps to take in an emergency
When trouble arises
IS F_EE
CAUTION
Using the tire jack
Improper use of the tire jack may lead to death or serious injuries due to the
vehicle suddenly falling off the jack.
Do not use the tire jack for any purpose other than replacing tires or
installing and removing tire chains.
Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replac-
ing tires on this vehicle.
Always check that the tire jack is securely set to the jack point.
Do not put any part of your body under the vehicle while it is supported
by the jack.
Do not start or run the engine while your vehicle is supported by the jack.
Do not raise the vehicle while someone is in it.
When raising the vehicle, do not put an object on or under the jack.
Do not raise the vehicle to a height greater than that required to replace the
tire.
Use a jack stand if it is necessary to get under the vehicle.
Take particular care when lowering the vehicle to ensure that no one work-
ing on or near the vehicle may be injured.
Replacing a flat tire
Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the vehicle is moving.
Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, resulting in death or serious injury.
• Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing a
serious accident. Remove any oil or grease from the wheel bolts or
wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 103 N
•m (10.5
kgf
•m, 76 ft•lbf) as soon as possible after changing wheels.
