The relays are coded as follows:
Fuse/Relay Location Description
Relay 64 Trailer Tow (left turn)

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Spare tire information
The spare tire can be used as a spare or a regular tire. The spare is
identical to the other tires on your vehicle, although the wheel will not
match.
If your vehicle is equipped with 4WD or AWD, a spare tire of a
different size than the road tires should not be used. Such a tire
could result in damage to driveline components and make the
vehicle difficult to control.
