ECO mode GMC ACADIA 2009 Owner's Manual

You can move the height adjuster
up by pushing up on the shoulder
belt guide.
After the adjuster is set to the desired
position, try to move it down without
pushing the button to make sure it
has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for the front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety belts
during the early stages of a moderate
to severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met. And,
for vehicles with side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced, and
probably other new parts for the
vehicle’s safety belt system. See
Replacing Restraint System Parts
After a Crash on page 1-62.
Rear Safety Belt Comfort
Guides
Rear shoulder belt comfort guides
may provide added safety belt
comfort for older children who have
outgrown booster seats and for
some adults. When installed on a
shoulder belt, the comfort guide
positions the shoulder belt away
from the neck and head.
There is a guide for each
outboard passenger position
in the second row seat and all
passenger positions in the third row.Here is how to install a comfort
guide to the safety belt:
1. For the outboard positions,
remove the guide from its storage
clip on the interior body.
For the third row center position,
locate the comfort guide which
is located in a storage pocket,
at the top of the seat, under
the headrest on the driver’s
side of the vehicle.Outboard Positions

Notice:The engine is designed
to work with the electronics
in the vehicle. If you add electrical
parts or accessories, you could
change the way the engine
operates. Before adding electrical
equipment, check with your
dealer/retailer. If you do not, the
engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. Some models
may have an internal thermostat in
the cord which will prevent
engine coolant heater operation at
temperatures above 0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
located on the driver side of the
engine compartment. It is
routed around the windshield
washer uid reservoir.
3. Plug the cord into a normal,
grounded 110-volt AC outlet.
{CAUTION
Plugging the cord into an
ungrounded outlet could cause an
electrical shock. Also, the wrong
kind of extension cord could
overheat and cause a re. You
could be seriously injured. Plug
the cord into a properly grounded
three-prong 110-volt AC outlet. If
the cord will not reach, use a
heavy-duty three-prong extension
cord rated for at least 15 amps.
4. Before starting the engine, be
sure to unplug and store the
cord as it was before to keep it
away from moving engine
parts. If you do not, it could be
damaged.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.

you continue to drive your vehicle
that way, you could damage the
transmission. Have your vehicle
serviced right away. You can drive
in LOW (L) when you are driving
less than 35 mph (56 km/h) and
DRIVE (D) for higher speeds
until then.
L (Low):This position gives you
access to gear ranges. This
provides more engine braking but
lower fuel economy than D (Drive).
You can use it on very steep
hills, or in deep snow or mud.
Electronic Range Select
(ERS) Mode
ERS mode allows you to choose
the top-gear limit of the transmission
and the vehicle’s speed while
driving down hill or towing a trailer.
The vehicle has an electronic
shift position indicator within the
