Dashboard and Switches

SPEEDOMETER

 

The speedometer on USA and Canadian cars was calibrated in miles-per-hour (MPH) instead of km/h. Also, the stopping distance was calibrated in feet.

RADIOS

 

We will not go into a detailed review of the radios used on USA and Canadian SM's here since the Citroenvie website has an excellent article on SM radios:

However, perhaps the most common radio used on USA/Canadian SM’s is shown in the photo.

The most common radio found on USA/Canadian SM's

All USA/Canadian SM’s were equipped with electric antennas, as were Euro cars. But due to radio differences with Euro cars, USA/Canadian SM’s often had unique switches mounted on the dashboard to operate the antenna. A variety of switches showed up, usually on the central console gage binnacle, left of the fuel and temperature gages. Most were ugly plastic switches unbefitting of the interior quality of an SM. The only aesthetically acceptable antenna switch, which was common on 1973's, can be seen in the photo below.

 

Since the plethora of uglier antenna switches do not show up in the parts book, we suspect that they may have been installed by Citroën personnel after the cars were in North America.

HEADLIGHT SWITCH

Euro cars had a headlight switch labelled with dots and with functionality to turn on/off the inner turning lights (photos below).

The headlight switch was different on all USA cars per the following:

  • 1971 USA SM’s had a headlight switch labelled with dots and no functionality to turn on/off the inner lights.

  • 1972 and 1973 USA SM’s had a switch labelled with the word “LIGHTS” and no functionality to turn on/off the inner lights (part number 5412295). 

Canadian cars we have examined used two of the above headlight switches as follows:

  • All of the early Canadian SM's (with Euro headlights) that we have been able to examine had the Euro headlight switch installed, but one reader indicated that his Canadian car was equipped with the early USA headlight switch.

  • Later Canadian cars with the USA headlights (1973 models) had the later USA headlight switch (P/N 5412295).

 

The parts books do not reflect all of these switch configurations.

WIPER SWITCH

 

The wiper switch was different on 1972 and 1973 USA/Canadian SM’s. The USA/Canadian version (Gelbon part number 5419296) had the words “WASH” and “WIPE” on the switch rather than symbols. We believe that this was due to a USA requirement of the era. Note that DS’s had a similar wiper switch change in 1972. 

 

There were not many 1971 SM’s imported to North America, but 1971’s seem to have the Euro wiper switch installed.

TURN SIGNAL SWITCH

 

Turn signal configurations on US and Canadian SM's were as follows:

 

  • 1971, 1972, and perhaps early 1973 SM's in the USA and Canada had a non-cancelling turn signal switch that is different than that of Euro cars. The USA switch does not have the passing headlight flasher function. The symbol on the bottom face of the switch for the passing flasher function is present on USA cars, but is not painted in, since the functionality is absent. Apparently, the switch manufacturer used the same molded plastic part for both Euro and North American switches, but only painted in the flasher symbol on switches that had the internal switch guts to include the passing function. 

  • Partway through model year 1973, US and Canadian SM's received self-cancelling turn signals. This required a different turn signal switch and different steering column  components. According to the parts book, this change seems to have occurred in 11/72, which if correct, means that early 1973 SM's did not receive this change. US Federal Motor Vehicle Safety Standard (FMVSS) #108 has required self-cancelling turn signals for many years. We presume that it is this requirement was behind this design change.

HAZARD LIGHTS

 

The parts book suggest intermittent installation of Hazard lights on a few European SM's, but they were installed on all USA/Canadian cars. Hazard lights were a USA requirement stemming from the late 1960’s. The hazard light switch location is per the following:

 

  • On 1971 and 1972’s, the hazard light switch was on the center console gage binnacle, left of the fuel and temperature gages. The switch was labelled with either a triangle or “G2”.

 

  • On 1973’s, the hazard light switch was relocated to the main dash board facia, just to the right of the STOP warning light oval. The switch was usually labeled “G2”.

 

Hazard light switches on DS’s were labelled “HAZ” or “G1”. On SM’s the hazard switch was labelled “G2” or with a triangle symbol. On USA/Canadian SM's, the word HAZARD was printed on the plastic gage housing, next to the switch. North American regulations of the era were behind some of these changes, but the origin of the G1 and G2 labelling is unclear.

DOOR BUZZER

A door buzzer was incorporated on all USA/Canadian SM’s. The buzzer module, made by AXO, was hooked into the door switches and the ignition switch. Most them were disconnected many years ago due to the irritating noise they made when a door was open. The buzzer module was the same part that was used on ‘70-‘72 USA DS’s (P/N 5422812). The logic was:

 

Either door open + ignition key inserted = buzzer on

DEFROSTER LEVER LABELLING

 

The defroster control on the dash of USA/Canadian cars had the abbreviation “DEF” added on the facia on some cars.

Unfortunately, the parts book is of little assistance to help sort this out. However, based on observation, there appear to be three versions of the defroster lever used on US/Canadian cars:

  • There were not many 1971's sold in North America, but the few we have found have no specific labelling for the defroster other than the 'up' arrow that European SM's had. 

  • 1972 SM's in the US and Canada typically had the letters "DEF" printed on the black facia. 

  • 1973 SM's in the US and Canada typically had a back-lit window in the facia that had the letters DEF. 

 

Note that similar “DEF” letting was added to the DS defroster lever in the 1972 time-frame as well. We believe this to be a USA requirement of the era.

GLOVE BOX DOOR BUTTON

 

All USA/Canadian (and Swedish) cars had a different button to open the glove box door that was not lockable. Most Euro SM’s had a lockable glove box. It is unclear what drove this change.

CHOKE KNOB

 

The choke knob on all USA/Canadian cars was labelled with the word “CHOKE” in lieu of a symbol. We believe that this was a USA requirement of the era.  We have been advised that the CHOKE lettering was simply a sticker that was placed over the symbol on the euro choke knob. This sticker tended to fall off, thus explaining the lack of consistency if we look at the choke knobs on cars today.
