DOES YOUR VEHICLE NEED
REPAIRING?
Be on the alert for changes in performance and sounds, and
visual tip-offs that indicate service is needed. Some important
clues are:
D Engine missing, stumbling, or pinging
D Appreciable loss of power
D Strange engine noises
D A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)
D Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)
D Flat-looking tires, excessive tire squeal when cornering,
uneven tire wear
D Vehicle pulls to one side when driving straight on a level
road
D Strange noises related to suspension movement
D Loss of brake effectiveness, spongy feeling brake pedal,
pedal almost touches floors, vehicle pulls to one side when
braking
D Engine coolant temperature continually higher than normal
If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or
repair.
