differential SUBARU WRX 2016 Owner's Manual

In case of emergency/Towing
Towing If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following
procedures for safety. WARNINGNever tow AWD models (both CVT
and MT models) with the front
wheels raised off the ground while
the rear wheels are on the ground,
or with the rear wheels raised off the
ground while the front wheels are on
the ground. This will cause the
vehicle to spin away due to the
operation or deterioration of the
center differential.
& Towing and tie-down hooks The towing hooks should be used only in
an emergency (e.g., to free a stuck vehicle
from mud, sand or snow).
CAUTION
. Use only the specified towing
hook and tie-down hook. Never
use suspension parts or other
parts of the body for towing or
tie-down purposes.
. To prevent deformation to the
front bumper and the towing
hook, do not apply excessive
lateral load to the towing hook. Front towing hook:
1. Take the towing hook, screwdriver and
wheel nut wrench out of the tool bucket.
2. Cover the tip of a flat-head screwdriver
with vinyl tape or cloth so that it will not
scratch the bumper. Insert the flat-head
screwdriver into the cutout of the cover
and pry open the cover.9-12
