Caution:
To help avoid injury to you or others when raising or lowering the convertible top, keep your hands away from any hinges and linkage and close all

Before performing any repair procedures, verify with owner that proper convertible top operating procedures and conditions have been observed as
follows:
^
Never raise or lower the top while the car is moving. The wind could get under it and cause damage.
^
If automatic car washes are used, it is recommended that a soft cloth car wash be used and the vehicle climate control system should be set to
"vent" and the fan be set at its highest speed. This will prevent the high pressure water from entering around the convertible top.
^
Do not try to lower or raise the convertible top if your vehicle is out in cold weather, 41°F (5°C) or below. The cold can cause cracks and other
damage to the convertible top as it is being lowered or raised.
^
Do not lower the convertible top if it is damp or wet. After the convertible top is down, the trapped water can cause stains, mildew and damage to
the inside of the vehicle. Be sure to dry off the convertible top before you lower it.
^
Make sure there is nothing in the convertible top storage well (the area behind the rear seat where the convertible top will go) or under the well in
the trunk. Even a small item could damage the rear window or convertible top when it is lowered.
^
The convertible top is not designed to carry weight. Never let anyone sit on the convertible top, and do not put anything on top of it when it is up
or down, or it could be damaged.
^
All side windows must be partially lowered before lowering or raising convertible top to prevent weatherstrip and seal damage or displacement
which could result in water and/or wind leaks.
Gathering detailed information from the vehicle owner is a valuable tool in locating and repairing water leaks. It may be necessary to ask leading
questions to the location and conditions when water leaks occur. Some helpful questions may be asked as follows:
1.
What area of the vehicle does water appear?
2.
Does water leak occur when it rains?
3.
Does water leak occur when vehicle is washed?
4.
Is vehicle washed in an automatic car wash or is it washed by hand?
5.
Have seals or weatherstrips been serviced previously?
6.
Have door or quarter windows been serviced previously?
7.
Has vehicle been in a collision at any time?
