CAUTION
Keep people and combustible materials away from the
exhaust pipe while the engine is running. The exhaust gas
is very hot.
 Do not drive, idle or park your vehicle over anything that
might burn easily such as grass, leaves, paper or rags.
NOTICE
A large amount of unburned gases flowing into the
three±way catalytic converter may cause it to overheat
and create a fire hazard. To prevent this and other
damage, observe the following precautions:
Use only unleaded gasoline.
 Do not drive with an extremely low fuel level; running
out of fuel could cause the engine to misfire, creating
an excessive load on the three±way catalytic converter.
 Do not allow the engine to run at idle speed for more
than 20 minutes.
 Avoid racing the engine.
 Do not push±start or pull±start your vehicle.
Do not turn off the ignition while the vehicle is moving.
 Keep your engine in good running order.
Malfunctions in the engine electrical system,
electronic ignition system or fuel system could cause
an extremely high three±way catalytic converter
temperature.
 If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check±up as soon
as possible. Remember, your Lexus dealer knows your
vehicle and its three±way catalytic converter system
best.
 To ensure that the three±way catalytic converter and
the entire emission control system operate properly,
your vehicle must receive the periodic inspections
required by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to the
separate ºOwner's Manual Supplement/
Maintenance Scheduleº.

STARTING AND DRIVING
212
To allow proper operation of your vehicle's
ventilation system, keep the inlet grilles in front of
the windshield clear of snow, leaves, or other
obstructions.
 If you smell exhaust fumes in the vehicle, drive with
the windows open and the trunk lid closed. Have the
cause immediately located and corrected.
BEFORE STARTING THE
ENGINE
1. Check the area around the vehicle before entering it.
2. Adjust seat position, seatback angle, head restraint height
and steering wheel angle.
3. Adjust inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts.

Starting the engine
Before starting the engine, be sure to follow the instructions
in ºBefore crankingº.
Normal starting procedure
The multiport fuel injection system/sequential multiport fuel
injection system in your engine automatically controls the
proper air±fuel mixture for starting. You can start a cold or
hot engine as follows:1. With your foot off the accelerator pedal, crank the engine
by turning the key to ºSTARTº. Release it when the engine
starts.
2. After the engine runs for about 10 seconds, you are ready
to drive.
If the weather is below freezing, let the engine warm up for
a few minutes before driving. Do not leave the vehicle while
the engine is warming up.
If the engine stalls ...
Simply
restart it , using the correct procedure given in normal
starting.
If the engine will not start
See ºIf your vehicle will not startº on page 275.
NOTICE
 Do not crank for more than 30 seconds at a time. This
may overheat the starter and wiring systems.
 Do not race a cold engine.
 If the engine becomes difficult to start or stalls
frequently, have the engine checked immediately.

STARTING AND DRIVING
219
(a) Normal driving
1. Start the engine as instructed in ºHow to start the
engineº on page 216.
The transmission must be in ºPº or ºNº. The engine will not
start in any drive position even if the ignition key is turned to
ºSTARTº.

STARTING AND DRIVING
231
(a) Normal driving
1. Start the engine as instructed in ºHow to start the
engineº on page 216.
The transmission must be in ºPº or ºNº. The engine will not
start in any drive position even if the ignition key is turned to
ºSTARTº.

STARTING AND DRIVING
242In the power mode, the ºECT PWRº light in the instrument
cluster is on and the transmission is shifted up at higher
vehicle speeds and shifted down more responsively than in
the normal mode.
To return to the normal mode, push the driving pattern
selector switch lightly on the ºSNOWº side.
Snow mode: For slippery road surfaces such as in snow. In
this mode, the spinning of the rear wheels is controlled
appropriately.
When you push the driving pattern selector switch on the
ºSNOWº side, the snow mode is turned on and the ºECT
SNOWº light in the instrument cluster comes on.
To return to the normal mode, push the driving pattern
selector switch on the ºSNOWº side again.
When you turn the ignition switch off in the snow mode, the
mode automatically changes to the normal mode.
CRUISE CONTROL
The cruise control allows you to cruise the vehicle at a
desired
speed over 40 km/h (25 mph) with your foot off the
accelerator pedal.
Your cruising speed can be maintained although a slight speed
change may occur when driving up or down a gradient, within
the limits of engine performance. On steeper hills, a great
speed change will occur so it is better to drive without the
cruise control.
When the cruise control is on, the driving pattern of the
automatic transmission is fixed in the normal position,
regardless of the position of the selector switch.
CAUTION
 To help maintain maximum control of your vehicle, do not
use the cruise control when driving in heavy or varying
traffic, or on slippery (rainy, icy or snow±covered) or
winding roads.
 Avoid vehicle speed increases when driving downhill. If the
vehicle speed is too fast in relation to the cruise control set
speed, cancel the cruise control then downshift the
transmission to use engine braking to slow down.

STARTING AND DRIVING
243
Turning on the system
To operate the cruise control, push the main switch. This
turns the system on. The indicator light in the instrument
cluster shows that you can now set your desired cruising
speed. Another push on the switch will turn the system
completely off.
When the ignition key is turned off, the main switch is also
automatically turned off. To use the cruise control again, push
the main switch again to turn it on.
CAUTION
To avoid accidental cruise control engagement, keep the main
switch off when not using the cruise control.
