GMC Acadia/Acadia Denali Owner Manual (GMNA-Localizing-U.S./Canada/
Mexico-9803770) - 2017 - crc - 7/12/16
356 Vehicle Care
For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components.
To tow the vehicle from the front
with all four wheels on the ground:1. Position the vehicle that will be towed and secure it to the
towing vehicle.
2. Remove the shift lever boot bypulling up on the rear of the
trim plate. 3. Use a small screwdriver or tool
to press and hold the manual
release button on the rear right.
4. Put the vehicle in N (Neutral).
Caution
If the vehicle is towed without
performing each of the steps
listed under “Dinghy Towing,” the
automatic transmission could be
damaged. Be sure to follow all
steps of the dinghy towing
procedure prior to and after
towing the vehicle.
Caution
If 105 km/h (65 mph) is exceeded
while towing the vehicle, it could
be damaged. Never exceed
105 km/h (65 mph) while towing
the vehicle.
Once the destination has been
reached: 1. Shift the vehicle to P (Park). 2. Reinstall the shift lever boot by
inserting the front edge and
pressing the rear of the trim
plate until it snaps into place.
3. Start the engine and let it idle for more than three minutes
before driving the vehicle.
Caution
Too much or too little fluid can
damage the transmission. Be
sure that the transmission fluid is
at the proper level before towing
with all four wheels on the
ground.
Caution
Do not tow a vehicle with the front
drive wheels on the ground if one
of the front tires is a compact
spare tire. Towing with two
different tire sizes on the front of
the vehicle can cause severe
damage to the transmission.
