clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)

Flat-looking tires, excessive tire squeal when cornering,
uneven tire wear

Vehicle pulls to one side when driving straight on a level
road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking

Engine coolant temperature continually higher than normalIf you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.

CHECKING THE ENGINE COOLANT
LEVEL

1Reservoir cap2Fº (upper) line
3Lº (lower) line
Look at the see-through coolant reservoir when the
engine is cold. The coolant level is satisfactory if it is
between the Fº and Lº lines on the reservoir. If the level
is low, add the coolant. (For the coolant type, see Coolant
type selectionº described below.)
The coolant level in the reservoir will vary with engine
temperature. However, if the level is on or below the Lº line,
add coolant. Bring the level up to the Fº line.
