1994 BUICK CENTURY ECU

If you need to replace any of your wheels, wheel bolts,
or wheel nuts, replace them only with new
GM original
equipment parts. This way,
you will be sure to have the
right wheel, wheel bolts, and wheel nuts for your Buick
model.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer/odometer
calibration, headlight aim, bumper height, vehicle
ground clearance, and tire
or tire chain clearance
to the body and chassis.
Used Replacement Wheels
Tire Chains
NOTICE:
Use tire chains only where legal and only when
you must. Use only
SAE Class “S” type chains
that are the proper size for your tires. Install
them on the front tires and tighten them as
tightly
as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions.
If you can hear the
chains contacting your vehicle, stop and
retighten them.
If the contact continues, slow
down
until it stops. Driving too fast with chains
on will damage your vehicle.
