Here are four things that some
owners ask about. None of these
show a problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge indicated the tank was
half full, but it actually took a
little more or less than half the
tank's capacity to fill the tank.
. The gauge moves a little while
turning a corner or speeding up.
. The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.Engine Coolant
Temperature Gauge

This gauge shows the engine
coolant temperature.
If the pointer moves toward the
warning area at the high end of the
gauge, the engine is too hot.
If the engine coolant has
overheated and the vehicle has
been operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible. See Engine

Manual regeneration can only be
used when the DPF has become at
least 90% full. At 100% full, it will
attempt to automatically self-clean if
proper driving conditions are met.
The DPF will clean itself if the
vehicle can be driven for about
30 minutes.
A DIC message displays when
manual regeneration is possible.
Scroll through the DIC pages to find
the Exhaust Cleaning menu.
Depending on whether the vehicle
has a base or uplevel cluster, it may
be under the Settings menu.
If the vehicle cannot be stopped
when the DIC message first
indicates cleaning is available,
automatic self-cleaning may have
begun. If conditions cannot be met
for self-cleaning to complete, and
manual regeneration is selected, it
may take up to four minutes for the
system to switch to manual
regeneration. When the switch
occurs, a DIC message prompts to
start the cleaning process.{Warning
Do not leave the vehicle during
the regeneration.
Make sure that there are no
flammable materials near the
muffler, DPF, and exhaust pipe
which may result in a fire.
The temperature of exhaust
gases is high enough to burn you.
You and others could be seriously
injured.
Before starting manual
regeneration, make sure all of the
following safety conditions are met:
. The vehicle is parked on level
ground, away from any
flammable materials.
. The vehicle is parked outdoors,
away from any walls or
buildings.
. The vehicle is at least 3 m (10 ft)
from any obstructions or
materials that may combust
or melt. .
The shift lever is in P (Park).
. The fuel tank is at least
one-eighth full.
. All fluids are at the proper level.

The vehicle can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts too
often under heavy loads and/or hilly
conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle could show signs similar to
engine overheating. To avoid this,
let the engine run, preferably on
level ground, with the transmission
in P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating0294.
Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and
trailer on a level surface when
possible. When parking your vehicle and your
trailer on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the
brake pedal to allow the chocks
to absorb the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.
. Shift into a gear.
. Release the parking brake.
2. Let up on the brake pedal. 3. Drive slowly until the trailer is
clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer
Towing
The vehicle needs service more
often when used to tow trailers. See
Maintenance Schedule 0368. It is
especially important to check the
automatic transmission fluid, engine
oil, axle lubricant, belts, cooling
system, and brake system before
and during each trip.
Check periodically that all nuts and
bolts on the trailer hitch are tight.

To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.
Use engine oil approved to the
proper specification and of the
proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
. Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil
Life System 0287.
. Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
Check the engine oil level regularly,
every 650 km (400 mi), especially
prior to a long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment Overview
0278 for the location.
{Warning
The engine oil dipstick handle
may be hot; it could burn you.
Use a towel or glove to touch the
dipstick handle.
If a low oil Driver Information Center
(DIC) message displays, check the
oil level. If the oil is not low and the
low oil message remains on, take
the vehicle to your dealer for
service.
Follow these guidelines:
. To get an accurate reading, park
the vehicle on level ground.
Check the engine oil level after
the engine has been off for at
least two hours. Checking the

{Warning
An underhood electric fan can
start up even when the engine is
not running and can cause injury.
Keep hands, clothing, and tools
away from any underhood
electric fan.
{Warning
Do not touch heater or radiator
hoses, or other engine parts.
They can be very hot and can
burn you. Do not run the engine if
there is a leak; all coolant could
leak out. That could cause an
engine fire and can burn you. Fix
any leak before driving the
vehicle.
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be at the
top rib on the middle of the tank. If it
is not, the vehicle may have a leak
at the radiator hoses, heater hoses,
radiator, water pump, or somewhere
else in the cooling system.
If there seems to be no leak, with
the engine on, check to see if the
electric engine cooling fan is
running. If the engine is overheating, the fan should be
running. If it is not, the vehicle
needs service. Turn off the engine.
Engine Coolant
The engine cooling system in the
vehicle is filled with DEX-COOL
engine coolant mixture. This coolant
needs to be checked and changed
at appropriate levels. See
Recommended Fluids and
Lubricants
0377 and
Maintenance Schedule 0368.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating 0294.
What to Use
{Warning
Plain water, or other liquids such
as alcohol, can boil before the
proper coolant mixture will. With
plain water or the wrong mixture,
the engine could get too hot but

292 Vehicle Care
Warning (Continued)
there would not be an overheat
warning. The engine could catch
fire and you or others could be
burned.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
. Gives freezing protection down
to−37 °C (−34 °F), outside
temperature.
. Gives boiling protection up to
129 °C (265 °F), engine
temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts.
. Helps keep the proper engine
temperature.
Caution
Do not use anything other than a
mix of DEX-COOL coolant that
meets GM Standard
GMW3420 and clean, drinkable
water. Anything else can cause
damage to the engine cooling
system and the vehicle, which
would not be covered by the
vehicle warranty.
Never dispose of engine coolant by
putting it in the trash, pouring it on
the ground, or pouring into sewers,
streams, or bodies of water. Have
the coolant changed by an
authorized service center, familiar
with legal requirements regarding
used coolant disposal. This will help
protect the environment and your
health.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level mark is not
visible, add a 50/50 mixture of
clean, drinkable water and
DEX-COOL coolant at the coolant
surge tank to the top rib on the
middle of the tank, but be sure the
cooling system is cool before this is
done. See Engine Overheating
0 294.

stop. This will allow any
pressure still left to be vented
out the discharge hose.
2. Keep turning the pressure cap slowly and remove it.
3. Fill the coolant surge tank withthe proper mixture to the
indicated level mark.
4. With the coolant surge tank pressure cap off, start the
engine and let it run until you
can feel the upper radiator
hose getting hot. Watch out for
the engine cooling fans. By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level reaches the
indicated level mark.
5. Replace the pressure cap tightly.
6. Verify coolant level after the engine is shut off and the
coolant is cold. If necessary,
repeat coolant fill procedure
Steps 1–6.
If the coolant still is not at the
proper level when the system
cools down again, see your
dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the
cap is properly and tightly
secured.
Engine Overheating
The vehicle has an engine coolant
temperature gauge on the
instrument cluster and overheat
messages in the Driver Information
Center (DIC) to warn of engine
overheating. See Engine Coolant
Temperature Gauge 0112.
The decision may be made not to lift
the hood when the engine coolant
temperature gauge is in the
overheat zone or an engine
overheat DIC message displays, but
instead to get service help right
away. See Roadside Assistance
Program 0389.
If the decision to lift the hood is
made, make sure the vehicle is
parked on a level surface. Then
check to see if the engine cooling
fan(s) are running. If the engine is
overheating, the fan(s) should be
running. If they are not, do not
continue to run the engine, and
have the vehicle serviced.
