Be on the alert for changes in performance, sounds, and visual tip-offs that indicate service is needed. Some important clues are as follows:

• Engine missing, stumbling, or pinging.
• Appreciable loss of power.
• Strange engine noises.
• A leak under the vehicle (however, water dripping from the air conditioner 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 tyre; excessive tyre squeal when cornering; uneven tyre 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 or clutch pedal; pedal almost touches floor; vehicle pulls to one side when braking.
• Engine temperature continually higher than normal.
• Engine continually runs hot; oil pressure gauge stays low.

CAUTION: Do not continue driving with the vehicle unchecked. It could result in serious vehicle damage and possibly personal injury.
