your keys inside the vehicle or trunk.
Insert your flat key in its key case as shown. We
recommend that you always carry this with you for
emergency use. Do not leave it in your vehicle.

A forward±facing child restraint system should
be put on the front seat only when it is
unavoidable. Always move the seat as far back
as possible, because the force of a deploying
airbag could cause death or serious injury to
the child. Do not allow the child to lean over the
front door or around the front door even if the
child is seated in a child restraint system. It is
dangerous if the side airbag inflates, and the
impact could cause death or serious injury to
the child.
 After installing the child restraint system, make
sure it is secured in place according to the
manufacturer's instructions. If it is not
restrained securely, it may cause death or
serious injury to the child in the event of a
sudden stop or accident.
When not using the child restraint system, keep it
secured with the seat belt or place it in the trunk or
somewhere other than in the passenger compartment.
This will prevent it from injuring passengers in the event
of a sudden stop or accident.
Your vehicle has anchors for securing the top strap of a
child restraint system. The anchor nuts are welded
beneath the sheet metal to permit installation of an
anchor bracket for a child restraint system. To install an anchor bracket, use an 8 mm X 30 mm X
1.25 mm coarse thread metric bolt and a 15 mm (0.6 in.)
spacer
for the outer anchors or a 10 mm (0.4 in.) spacer
for the center anchor. Note that the bolts accompanying
many child restraint systems are not metric. You can
damage the anchor nuts on your vehicle if you force
bolts with different thread into the anchor nuts.
For instructions about how to install the anchor bracket,
see ºTop strap anchors and locationsº.
If your child restraint system does not provide any of the
necessary parts, you can purchase the following items
from your Lexus dealer.
 CRS installation kit (Part No. 04731±22012)
± contains 1 bolt, 3 types of spacer and 1 locking clip.

DRIVING TIPS

HOW TO SAVE FUEL AND
MAKE YOUR VEHICLE LAST LONGER
Getting more kilometer/mileage from a liter/gallon of fuel
is easy ± just take it easy. It will help make your vehicle
last longer, too. Here are some specific tips on how to
save money on both fuel and repairs:
 Keep your tires inflated at the correct pressure.
Check the pressure every two weeks, or at least once
a month. Underinflation causes tire wear and wastes
fuel.
 Do not carry unneeded weight in your vehicle.
Excess weight puts a heavier load on the engine,
causing greater fuel consumption.
 Avoid lengthy warm±up idling. Once the engine is
running smoothly, begin driving ± but gently.
Remember, however, that on cold winter days this
may take a little longer.
 Accelerate slowly and smoothly. Avoid jackrabbit
starts.
 Avoid long engine idling. If you have a long wait
and you are not in traffic, it is better to turn off the
engine and start again later.
 Avoid engine overrevving. Use a gear position
suitable for the road on which you are traveling. 
Avoid continuous speeding up and slowing
down. Stop±and±go driving wastes fuel.

IN CASE OF AN EMERGENCY

B: If no steam is coming from your engine:
Leave the engine running and turn off the air
conditioning. Check the following.

Is the cooling fan operating?
 Is the coolant in the acceptable range?
 Is the engine drive belt O.K.?
CAUTION
When the engine is running, keep hands and clothing
away from the moving fan and engine drive belt.
 Do not attempt to remove the radiator cap when the
engine and radiator are hot. Serious injury could
result from scalding hot fluid and steam blown out
under pressure.
If the cooling fan is not operating or the coolant is not in
the acceptable range, turn off the engine and call your
Lexus dealer.
If both conditions are O.K., after the engine coolant
temperature has cooled to normal, continue driving your
vehicle.
If the engine coolant temperature does not cool down, or
your vehicle overheats again, have it checked as soon
as possible by your Lexus dealer.IF YOU HAVE A FLAT TIRE
