2. Go to the front of thevehicle and locate the
secondary release lever
under the front center of
the hood. Push the
secondary hood release
lever to the right to
release. 3. After you have partially
lifted the hood, the gas
strut system will
automatically lift the hood
and hold it in the fully open
position.
To close the hood: 1. Before closing the hood, be sure all filler caps are on
properly, and all tools are
removed.
2. Pull the hood down until the strut system is no
longer holding up the hood.
3. Allow the hood to fall. Check to make sure the
hood is latched completely.
Repeat this process with
additional force if
necessary.
{Warning
Do not drive the vehicle if
the hood is not latched
completely. The hood could
open fully, block your vision,
and cause a crash. You or
others could be injured.
Always close the hood
completely before driving.

Engine Oil
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 0373.
.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
Overview0367 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.
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 engine
oil level on steep grades or
too soon after engine
shutoff can result in
incorrect readings. Accuracy
improves when checking a
cold engine prior to starting.
Remove the dipstick and
check the level.
.If unable to wait two hours,
the engine must be off for at
least 15 minutes if the

Warning (Continued)
you could be burned. Never
turn the cap when the
cooling system, including the
pressure cap, is hot. Wait for
the cooling system and
pressure cap to cool.
Caution
Failure to follow the specific
coolant fill procedure could
cause the engine to
overheat and could cause
system damage. If coolant is
not visible in the surge tank,
contact your dealer.
The coolant surge tank
pressure cap can be removed
when the cooling system,
including the surge tank
pressure cap and upper
radiator hose, is no longer hot.
Coolant Fill Instructions
(3.6L Engine Only)
1. Turn the pressure cap slowly counterclockwise.
If a hiss is heard, wait for
that to stop. A hiss means
there is still some
pressure left.
2. Keep turning the pressure cap slowly and remove it.
3. Fill the coolant surge tankwith the proper mixture to
the mark pointed to on the
front of the coolant
surge tank.
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

Bulb Replacement
LED Lighting
This vehicle has all LED lamps.
For replacement of any LED
lighting assembly, contact
your dealer.
Electrical System
Electrical System
Overload
The vehicle has fuses and
circuit breakers to protect
against an electrical system
overload.
When the current electrical
load is too heavy, the circuit
breaker opens and closes,
protecting the circuit until the
current load returns to normal
or the problem is fixed. This
greatly reduces the chance of
circuit overload and fire
caused by electrical problems.Fuses and circuit breakers
protect power devices in the
vehicle.
If there is a problem on the
road and a fuse needs to be
replaced, the same amperage
fuse can be borrowed. Choose
some feature of the vehicle
that is not needed to use and
replace it as soon as possible.
To check a fuse, look at the
band inside the fuse. If the
band is broken or melted,
replace the fuse. Be sure to
replace a bad fuse with a fuse
of the identical size and rating.
Replacing a Blown Fuse
1. Turn off the vehicle.
2. Locate the fuse puller in
the engine compartment
fuse block.

3. Use the fuse puller toremove the fuse from the
top or side, as shown
above. 4. If the fuse must be
replaced immediately,
borrow a replacement fuse
with the same amperage
from the fuse block.
Choose a vehicle feature
that is not needed to
safely operate the vehicle.
Repeat Steps 2-3.
5. Insert the replacement fuse into the empty slot of
the blown fuse.
At the next opportunity, see
your dealer to replace the
blown fuse.
Headlamp Wiring
An electrical overload may
cause the lamps to go on and
off, or in some cases to remain
off. Have the headlamp wiring
checked right away if the
lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats
due to heavy snow or ice, the
windshield wipers will stop
until the motor cools and will
then restart.
Although the circuit is
protected from electrical
overload, overload due to
heavy snow or ice may cause
wiper linkage damage. Always
clear ice and heavy snow from
the windshield before using
the windshield wipers.
If the overload is caused by an
electrical problem and not
snow or ice, be sure to get it
fixed.
Fuses and Circuit
Breakers
The wiring circuits in the
vehicle are protected from
short circuits by a combination
of fuses and circuit breakers.
This greatly reduces the
chance of damage caused by
electrical problems.

{Danger
Fuses and circuit breakers
are marked with
their ampere rating. Do not
exceed the
specified amperage rating
when replacing fuses and
circuit breakers. Use of an
oversized fuse or circuit
breaker can result in a
vehicle fire. You and others
could be seriously injured or
killed.
{Warning
Installation or use of fuses
that do not meet GM’s
original fuse specifications is
dangerous. The fuses could
fail, and result in a fire. You(Continued)

or others could be injured or
killed, and the vehicle could
be damaged.
See Accessories and
Modifications 0363 and
General Information 0363.
To check or replace a blown
fuse, see Electrical System
Overload 0390.
Engine Compartment
Fuse Block
The underhood fuse block is in
the engine compartment, on
the driver side of the vehicle.
Caution
Do not pull the engine
compartment fuse block
lever, since it is intended
only for service purposes.
If pulled, vehicle malfunction
may occur.
Caution
Spilling liquid on any
electrical component on the
vehicle may damage it.
Always keep the covers on
any electrical component.
