STARTING AND DRIVING
306To initialize the system, perform the following:
1. Park the vehicle in a safe place and turn the ignition switch
to the “OFF” position.
2. Adjust the pressure of all the installed tires to the specified
cold tire inflation pressure level. (See “Tire and wheels” on
page 420.)
3. Turn the ignition switch to the “ON” position.
4. Push and hold the tire pressure warning reset switch until
the tire pressure warning light blinks slowly three times.
5. Wait for a few minutes with the ignition switch “ON”, and
then turn the ignition switch to the “OFF” position.
If you push the tire pressure reset switch while the vehicle is
moving, initialization is not performed.
If you push the tire pressure reset switch accidentally and
initialization is performed, adjust the tire inflation pressure to
the specified level and initialize the system again.
31x609
If the tire pressure warning light does not blink slowly three
times when you push and hold the reset switch, initialization
has failed and the tire pressure warning system may not work
properly. In this case, initialize the system again. If
initialization
cannot be performed, have the system checked at
your Lexus dealer.
CAUTION
Do not push the reset switch without first adjusting the
tire inflation pressure to the specified level. Otherwise,
the tire pressure warning light may not come on even if
the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.

Tire pressure warning select switch

1Main position 22nd position
2 sets of tire pressure warning valve and transmitter ID codes
can be registered.
Once a second set of tires is registered at “2nd”, you can switch
between tire set settings simply by pressing the tire pressure
warning select switch.
There are 2 settings
“MAIN” position: The ID code of the tire pressure warning valve
and transmitter on the tires originally installed on the vehicle is
registered.
“2nd” position: The code is not registered. When you replace
a new set of tires, purchase tire pressure warning valves and
transmitters from your Lexus dealer and have the new ID code
registered by your Lexus dealer. If the tire pressure select switch is set to the wrong tire setting,
the system will not work properly. After about 1 hour, the tire
pressure
warning light blinks to indicate a system malfunction.

Brakes and safety chains
Lexus recommends trailers with brakes that conform to
any applicable federal and state/provincial regulations.
A safety chain must always be used between the towing
vehicle and the trailer. Leave sufficient slack in the
chain for turns. The chain should cross under the
trailer tongue to prevent the tongue from dropping to
the ground in case it becomes damaged or separated.
For correct safety chain procedures, consult your
Lexus dealer.
CAUTION
If the total trailer weight exceeds 453 kg (1000 lb.),
trailer brakes are required.
Never tap into your vehicle’s hydraulic system as it
will lower its braking effectiveness.
Never tow a trailer without using a safety chain
securely attached to both the trailer and the vehicle.
If damage occurs to the coupling unit or hitch ball,
there is possible danger of the trailer wandering over
into another lane.
Tires
Ensure that your vehicle’s tires are properly inflated. Adjust
the tire inflation pressure to the recommended cold tire
inflation pressure indicated below:
Tire inflation pressure, kPa (kgf/cm
2 or bar, psi)
Front 220 (2.2, 32)
Rear 240 (2.4, 35)
The trailer tires should be inflated to the pressure
recommended by the trailer manufacturer in respect to the
total trailer weight.

HOW TO SAVE FUEL AND MAKEYOUR VEHICLE LAST LONGER
Improving fuel economy 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 over revving. 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.
Avoid unnecessary stopping and braking. Maintain a
steady pace. Try to time the traf fic signals so you only need
to stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also
reduce wear on your brakes.
Avoid heavy traffic or traffic jams whenever possible.
Do not rest your foot on the brake pedal. This causes
premature wear, overheating and poor fuel economy.
Maintain a moderate speed on highways. The faster you
drive, the greater the fuel consumption. By reducing your
speed, you will cut down on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting
the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an
extra load on the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free from mud, etc.
This not only lessens weight but also helps prevent
corrosion.
