the position of the lower anchorages below the tag in the
seatback.
2. Latch the hooks of lower straps onto the anchorages
and tighten the lower straps.
Type B:
1. Widen the clearance at the lower seatback and confirm
the position of the lower anchorages below the tag in the

2. Latch the buckles onto the anchorages.
If your child restraint system has a top strap, it should be
anchored.
(For the installation of the top strap, see ºUsing a top
strapº on page 159 or 164.)
For the installation details, refer to the instruction manual
equipped with each product.
CAUTION
 When using the lower anchorages for the child
restraint system, be sure that there are no irregular
objects around the anchorages or that the seat belt is
not caught.
 Push and pull the child restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided by its
manufacturer.
 Do not put a child restraint system on the rear seat if
it interferes with the lock mechanism of the front
seats. This can cause death or severe injury to the
child and front passenger in case of sudden braking
or a collision.

DRIVING TIPS
260

Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.WINTER DRIVING TIPS
Make sure you have a proper freeze protection of engine
coolant.
Your coolant must contain ethylene±glycol type coolant for a
proper corrosion protection of aluminum components. Use
ºToyota Genuine Long Life Coolantº or equivalent. See
ºChecking the engine coolant levelº on page 319 for
instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60% solution
for your Lexus, to provide protection down to about ±50 C
(±58 F). Do not use more than 70% solution for better coolant
performance.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 348 tells you how to visually inspect the battery.
Your Lexus dealer and most service stations will be pleased to
check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold
weather.
See page 317 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call
your Lexus dealer ± they will be pleased to help.
