LUGGAGE STOWAGEPRECAUTIONS
When stowing luggage or cargo in the vehicle, observe
the following:
Put luggage or cargo in the trunk when at all possible. Be
sure all items are secured in place.
 Be careful to keep the vehicle level. Placing the weight as
far forward as possible helps maintain vehicle balance.
 For better fuel economy, do not carry unnecessary weight.
CAUTION
Do not place anything on the package tray behind the
rear seatback. Such items may be thrown about and
possibly injure people in the vehicle during sudden
braking or in an accident.
 Do not drive with objects left on top of the instrument
panel. They may interfere with the driver's field of
view. Or they may move during sharp vehicle
acceleration or turning, and impair the driver's
control of the vehicle. In an accident they may injure
the vehicle occupants.
NOTICE
Do not load the vehicle beyond the vehicle capacity
weight specified on the tire pressure label.

Luggage security system
SS15013
After closing the trunk lid, insert the master key and turn
it counterclockwise to deactivate the lock release lever.
At this time, the trunk lid can be opened only by the
phosphorescent handle lever inside the trunk.
FUEL TANK CAP
SS15008
1. To open the fuel filler door, pull the lever up.
When refueling, turn off the engine.
CAUTION
Do not smoke, cause sparks or allow open flames
when refueling. The fumes are flammable.
 When opening the cap, do not remove the cap
quickly. In hot weather, fuel under pressure could
cause injury by spraying out of the filler neck if the
cap is suddenly removed.

EXTERIOR EQUIPMENT

SV15009
2. To remove the fuel tank cap, turn the cap slowly
counterclockwise, then pause slightly before removing it.
After removing the cap, hang the tether as shown in the
illustration.
It is not unusual to hear a slight swoosh when the cap is
opened. When installing the cap, turn the cap clockwise until
you hear a click.
If the cap is not tightened securely, the malfunction indicator
lamp comes on. Make sure the cap is tightened securely.
The indicator lamp goes off after driving several times. If the
indicator lamp does not go off, contact your Lexus dealer as
soon as possible.
CAUTION
 Make sure the cap is tightened securely to prevent
fuel spillage in case of an accident.
 Use only a genuine Lexus fuel tank cap for
replacement. It is designed to regulate fuel tank
pressure.
Refueling the vehicle
As soon as the correctly operated nozzle switches off
automatically for the first time, the tank is full. Do not try
to add more fuel, because fuel may spill out.

DRIVING TIPS

TRAILER TOWING
SV32001
Lexus does not recommend towing a trailer with your
vehicle. It is not designed for trailer towing.
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.

NOTICE
Do not use gasohol other than stated above. It willcause fuel system damage or vehicle performanceproblems.
If driveability problems are encountered (poor hotstarting, vaporizing, engine knock, etc.), discontinueits use.
Take care not to spill gasohol during refueling.Gasohol may cause paint damage.

FACTS ABOUT ENGINE OIL CONSUMPTION
Functions of engine oil
Engine oil has the primary function of lubricating and cooling
the inside of the engine, and plays a major role in maintaining
the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume some engine
oil during normal engine operation. The causes of oil
consumption in a normal engine are as follows.
Oil is used to lubricate pistons, piston rings and cylinders.
A thin film of oil is left on the cylinder wall when a piston
moves downwards in the cylinder. High negative pressure
generated when the vehicle is decelerating sucks some of
this oil into the combustion chamber. This oil as well as
some part of the oil film left on the cylinder wall is burned by
the high temperature combustion gases during the
combustion process.
 Oil is also used to lubricate the stems of the intake valves.
Some of this oil is sucked into the combustion chamber
together with the intake air and is burned along with the fuel.
High temperature exhaust gases also burn the oil used to
lubricate the exhaust valve stems.

CAUTION
The reservoir may be hot so be careful not to burn
yourself.
NOTICE
Avoid overfilling, or the power steering could bedamaged.
When adding the power steering fluid, avoid spillingit. The generator under the power steering reservoircould be damaged if fluid is spilled on it.
CHECKING TIRE PRESSURE
SV61004
The recommended cold tire pressures, tire size and the
vehicle capacity weight are given on the label.
You should check the tire pressures every two weeks, or at
least once a month. And don't forget the spare! The pressure
for the spare tire should be the same with that for the standard
tire. (See page 250.) Incorrect tire pressure can reduce tire
life and make your vehicle less safe to drive.
Low tire pressure results in excessive wear, poor handling,
reduced fuel economy, and the possibility of blowouts from
overheated tires. Also, low tire pressure can cause poor
sealing of the tire bead. If the tire pressure is excessively low,
there is the possibility of wheel deformation and/or tire
separation. So keep your tire pressures at the proper level.
If a tire needs frequent refilling, have it checked by your Lexus
dealer.
