MAINTENANCE
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
D Engine continually runs hot; oil pressure gauge stays low.

If you notice any of these clues, take your vehicle to your Lexus
dealer as soon as possible. It probably needs adjustment or repair.
CAUTION
Do not continue driving with the vehicle unchecked. It could
result in serious vehicle damage and possibly personal injury.
