(n) Engine Oil Replacement Reminder Light
This light reminds you when to replace the engine oil.
This light will come on when the ignition key is turned to ONº
and will go off after about a few seconds.
When you drive for about 7200 km (4500 miles) after the
engine oil replacement, this light illuminates for about 3
seconds and then flashes for about 12 seconds with the
ignition key turned to ONº position. If you continue driving
without the engine oil replacement, and if the driving range
exceeds 8000 km (5000 miles), the light will come on after the
ignition key is turned to ONº position. The light will remain on
thereafter.
If the light is flashing, we recommend that you replace the
engine oil at an early opportunity depending on the driving and
road condition. If the light comes on, replace it as soon as
possible.
You need to reset the light after the engine oil replacement.
Reset the light by following the procedure below:
1. Turn the ignition key to the OFFº position with the odometer
reading shown. (For details, see Odometer and trip meterº on
page 57.)
2. Turn the ignition key to the ONº position while holding down
the trip meter reset knob.
Hold down the knob until the light goes off. Before the light
goes off, it illuminates for 3 seconds, flashes for 2 seconds and
illuminates for 1 second.
If the system fails to reset, the light will remain flashing. In this
case, return to step 1 and try again.
(o) Low Tire Pressure Warning Light
This light warns that the tire pressure of one or more of your
tires (including the spare tire) is low. The light comes on when
the ignition key is turned to the ONº position. It goes off after
a few seconds. This indicates that the tire pressure warning
system is functioning properly.
If the warning light comes on, stop your vehicle in a safe place
as soon as possible and check that the inflation pressure of all
tires (including the spare tire) is as specified on the tire and
loading information label. (See Checking tire inflation
pressureº on page 557.) The light should go off a few minutes
after the tire pressure is adjusted.
If the warning light blinks, the tire pressure warning system
may be malfunctioning. Contact your Lexus dealer.
For details, see Tire pressure warning systemº on page 417.
(p) Low Fuel Level Warning Light
This light comes on when the fuel level in the tank becomes
very low. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.
(q) Low Washer Fluid Warning Light
This light comes on when the fluid level in the tank becomes
very low. Fill the tank as soon as possible.

DRIVING TIPS
438
WINTER DRIVING TIPS
Make sure your coolant is properly protected against
freezing.
Only use Toyota Super Long Life Coolantº or similar high
quality ethylene glycol based non- silicate, non- amine,
non- nitrite, and non- borate coolant with long- life hybrid
organic acid technology.
See Checking the engine coolant levelº on page 545 for
details of coolant type selection.
Toyota Super Long Life Coolantº is a mixture of 50% coolant
and 50% deionized water. This coolant provides protection
down to about -35C (-31F).
NOTICE
Do not use plain water alone.
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 589 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 544 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 Ð they will be pleased to help.
Check the electronic ignition system for loose
connections or obvious damage.
Keep the door locks from freezing.
Squirt lock de-icer or glycerine into the locks to keep them from
freezing.

4. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the
vehicle.
Turn the wheel nuts counterclockwise to loosen them.
To get maximum leverage, fit the wrench to the nut
so that the handle is on the right side, as shown
above. Grab the wrench near the end of the handle
and pull up on the handle. Be careful that the wrench
does not slip off the nut.
Do not remove the nuts yet Ð just unscrew them
about one-half turn.
CAUTION
Never use oil or grease on the bolts or nuts.
The nuts may loose and the wheels may fall off,
which could cause a serious accident.

ENGINE
540The amount of engine oil consumed depends on the
viscosity of the oil, the quality of the oil and the way the
vehicle is driven.
More oil is consumed by high-speed driving and frequent
acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings
and cylinder walls have not become conditioned.
Oil consumption: Max. 1.0 L per 1000 km (1.1 qt./600 miles,
0.9 lmp. qt./600 miles)
When judging the amount of oil consumption, keep in
mind that the oil may have become diluted, making it
difficult to judge the true level accurately.
For example, if a vehicle is used for repeated short trips and
consumes a normal amount of oil, the dipstick may not show
any drop in the oil level at all, even after 1000 km (600 miles)
or more. This is because the oil is gradually becoming diluted
with fuel or moisture, making it appear that the oil level has not
changed.
The diluting ingredients evaporate out when the vehicle is then
driven at high speeds, as on an expressway, making it appear
that oil is excessively consumed after driving at high speeds.
Importance of engine oil level check
One of the most important points in proper vehicle
maintenance is to keep the engine oil at the optimum level so
that oil function will not be impaired. Therefore, it is essential
that the oil level be checked regularly. Lexus recommends that
the oil level be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to
serious engine trouble due to insufficient oil.
For detailed information on oil level check, see Checking the
engine oil levelº described below.USED ENGINE OIL
