1
Before driving ■
When the fuel filler door cannot be opened by pressing the inside switch
Open the back door and li ft the deck board up. (  P. 6 6 4 )
With a compact spare tire only:
Remove the spare tire cover. (  P. 664)
Remove the 12-volt battery cover. (  P. 664)
Install the 12-volt battery cover using the clips. (  P. 6 6 7 )
Using the lever to open the fuel filler door may not allow for an adequate reduction
in fuel tank pressure before refueling. To prevent fuel from spilling out, turn the cap
slowly when removing it.
During refueling, fuel may spill out from the filler opening due to air being dis-
charged from inside the fuel tank. Therefore, fill the fuel tank carefully and slowly.■

1682-1. Driving procedures
■
Drum-in-disc type parking brake system
Your vehicle has a drum-in-disc type parking brake system. This type of brake sys-
tem needs bedding-down of the brake shoe s periodically or whenever the parking
brake shoes and/or drum are replaced. Have your Lexus dealer perform the bed-
ding down operation.■
Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability of the
correct fuel. (  P. 800)■
For efficient use ●
Shift the shift lever to D when driving.
In the N position, the gasoline engine op erates but electricity cannot be gener-
ated. The hybrid battery (traction battery) will discharge, requiring unnecessary
engine power to recharge.●
Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and decel-
eration will make more effective use of the electric motor (t raction motor) with-
out having to use gasoline engine power.●
Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving with
the accelerator pedal slightly released.●
Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time may dis-
charge the hybrid battery. The vehicle cannot run if the hybrid battery is dis-
charged.■
Eco-friendly driving
 P. 1 9 9
CAUTION
■
When starting the vehicle
Always keep your foot on the brake pe dal while stopped with the hybrid system
operating. This prevents the vehicle from creeping.

Do not expose the vehicle to direct sunlight for extended pe riods of time. Park
the vehicle in the shade, especially during summer.●
Do not place items made of vinyl, plastic, or that contain wax on the upholstery, as
they may stick to the leather surface if th e vehicle interior heats up significantly.■
Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio syst em may be damaged if water comes into
contact with electrical components under the floor of vehicle. Water may also
cause the body to rust.■
Cleaning the inside of the rear window ●
Do not use glass cleaner to clean the re ar window, as this may cause damage to
the rear window defogger heater wires or antenna. Use a cloth dampened with

Vehicle specifications ■
Lexus recommends the use of gasoline containing detergent additives ●
Lexus recommends the use of gasoline that contains detergent additives to
avoid build-up of engine deposits.●
All gasoline sold in the U.S.A. contains minimum detergent additives to clean
and/or keep clean intake systems, per EPA’s lowest additives concentration pro-
gram.●
Lexus strongly recommends the use of Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gasoline and a list of marketers, please go to
the official website www.toptiergas.com.■
Lexus recommends the use of cleaner burning gasoline
Cleaner burning gasoline, including reform ulated gasoline that contains oxygen-
ates such as ethanol or MTBE (Methyl Te rtiary Butyl Ether) is available in many
areas.
Lexus recommends the use of cleaner burning gasoline and appropriately blended
reformulated gasoline. These types of gasoline provide excellent vehicle perfor-
mance, reduce vehicle emissions and improve air quality.■
Lexus does not recommend blended gasoline
●
If you use gasohol in your Lexus, be sure that it has an octane rating no lower
than 87.
●
Lexus DOES NOT recommend the use of gasoline containing methanol. ●
Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).DO NOT use gasoline contain-
ing more than 15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)

8126-1. Specifications
■
Lexus does not recommend gasoline containing MMT
Some gasoline contains oc tane enhancing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus DOES NOT recommend the use of gasoline that contains MMT. If fuel con-
taining MMT is used, your emission control system may be adversely affected.
The malfunction indicator lamp on the inst rument cluster may come on. If this hap-
pens, contact your Lexus dealer for service.
NOTICE■
Notice on fuel quality ●
Do not use improper fuels. If improper fuels are used, the engine will be dam-
aged.●
Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic convert-
ers causing the emission control system to malfunction.●
Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance problems.●
Using unleaded gasoline with an octane number or rating lower than that stated
here will cause persistent heavy knocking.
At worst, this will lead to engine damage.■
Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor hot start-
ing, vaporization, engine knoc king, etc.), discontinue the use of that type of fuel.■
When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
