STARTING AND DRIVING

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.
ENGINE EXHAUST CAUTION
CAUTION
Avoid inhaling the engine exhaust. It contains carbon
monoxide, which is a colorless and odorless gas. It
can cause unconsciousness or even death.
Make sure the exhaust system has no holes or loose
connections. The system should be checked from
time to time. If you hit something, or notice a change
in the sound of the exhaust, have the system checked
immediately.
Do not run the engine in a garage or enclosed area
except for the time needed to drive the vehicle in or
out. The exhaust gases cannot escape, making this
a particularly dangerous situation.
Do not remain for a long time in a parked vehicle with
the engine running. If it is unavoidable, however, do
so only in an unconfined area and adjust the heating
or cooling system to force outside air into the vehicle.
Keep the trunk lid closed while driving. An open or
unsealed trunk lid may cause exhaust gases to be
drawn into the vehicle. If you must drive with the
trunk lid open to accommodate a large object, close
the windows, open all the dashboard vents and have
the heating or cooling system deliver fresh air into
the vehicle by turning the fan to high speed with the
air intake control button in the OUTSIDE AIR mode.
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.
STARTING AND DRIVING

(b) Using engine braking
To use the braking power of the engine, downshift the
transmission in the way described below:
1
Shift into the “3” position. The transmission will downshift
to the third gear.
2
Shift into the “2” position. The transmission will downshift
to the second gear when the vehicle speed is or becomes
lower than 134 km / h (83 mph) and more powerful engine
braking will be obtained.
3
Shift into the “L” position. The transmission will downshift
to the first gear when the vehicle speed is or becomes
lower than 73 km / h (45 mph) and maximum engine
braking will be applied.
CAUTION
Be careful when downshifting on a slippery surface. The
abrupt change in engine speed could cause the vehicle
to spin or skid.
NOTICE
Be careful not to overrev the engine. Watch the
tachometer to keep engine rpm from going into the
red zone. The approximate maximum allowable
speed for each position is given below for your
reference:
“2”... 134 km / h (83 mph)
“L”... 73 km / h (45 mph)
Do not continue hill climbing or hard towing for a long
time in the “2” or “L” position. This may cause severe
automatic transmission damage from overheating.
To prevent such damage, “3” position should be
used in hill climbing or hard towing.
