Driving and Operating
Here is an example of proper truck and
camper match:
cargo load should not exceed the truck's
cargo weight rating, and the camper's
center of gravity (1) should fall within
the truck's recommended center of
gravity zone (2) when installed.
exceed the vehicle's gross vehicle
weight rating (GVWR). These ratings are
given on the Certification/Tire label
attached to the B-pillar. See
“Certification/Tire Label” under Vehicle
Load Limits 0 204. If weight ratings are
exceeded, move or remove items to
bring all weights below the ratings.
Any accessories or other equipment
that are added to the vehicle must be
weighed. Then, subtract this extra
weight from the CWR. This extra weight
may shorten the center of gravity zone
of the vehicle.
See your dealer for more information
on curb weights, cargo weights, Cargo
Weight Rating, and the correct center of
gravity zone.
If the slide-in camper and its load
weighs less than the CWR, the center of
gravity zone for the vehicle may be
larger.

New Vehicle Break-In
Caution
During the first 800 km (500 mi) of
driving this vehicle, overall performance
will benefit by following these break-in
period recommendations:
1. Camper Center of Gravity
2. Recommended Center of Gravity
Location Zone
Secure loose items to prevent weight
shifts that could affect the balance of
the vehicle. When the truck-camper is
loaded, drive to a scale and weigh on
the front and on the rear wheels
separately to determine axle loads.
Individual axle loads should not exceed
either of the gross axle weight ratings
(GAWR). The total axle loads should not
When the truck is used to carry a
slide-in camper, the total cargo load of
the truck consists of the manufacturer's
camper weight figure, the weight of

The remote key must be in the vehicle for
the system to operate. If the pushbutton

near a strong radio antenna signal causing
interference to the Keyless Access system.
See Remote Key Operation 0 12.
Caution (Continued)
.
Avoid exceeding the following engine
speeds when accelerating or
downshifting to slow or brake the
vehicle:
Electrical systems will adapt and calibrate
during the break-in period. A one-time
occurrence of clicks and similar vehicle
noises is normal during this process.
Gasoline engines: 4000 rpm
Diesel engines: 3000 rpm
To shift out of P (Park), the vehicle must be
on and the brake pedal must be applied.
Normal driving charges the vehicle’s battery
to achieve the best operation of the vehicle,
including fuel economy and the Stop/Start
System. See Stop/Start System 0 214.
.
.
Avoid making hard stops for the first
300 km (200 mi). Hard stops with new
brake linings can result in premature
wear and earlier replacement. Follow
this guideline every time brake linings
are replaced.
Warning
{
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, only shut the
vehicle off in an emergency.
Ignition Positions
Do not tow a trailer. See Trailer
Towing 0 303 for the trailer towing
capabilities of the vehicle and more
information.
Stopping the Engine/LOCK/OFF (No Indicator
Lights) : When the vehicle is stopped, press
ENGINE START/STOP once to turn the
engine off.
After the break-in period, the engine
speed and load can be gradually
increased.
If the vehicle is in P (Park), the vehicle will
turn off, and Retained Accessory Power (RAP)
will remain active. See Retained Accessory
Power (RAP) 0 216.

Driving and Operating
If the vehicle is not in P (Park), the vehicle
will return to accessory mode and display
the message SHIFT TO PARK in the Driver
Information Center (DIC). When the vehicle is
shifted into P (Park), the vehicle will turn off.
2. Brake using a firm and steady pressure.
Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
With the vehicle off, pressing the ENGINE
START/STOP button one time without the
brake pedal applied will place the vehicle in
accessory mode.
3. Shift the vehicle to N (Neutral). This can
be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location.
The vehicle will switch from accessory mode
to off after five minutes to prevent battery
rundown.
The vehicle may have an electric steering
column lock. The lock is activated when the
ignition is turned off and driver door is
opened. A sound may be heard as the lock
actuates or releases. The steering column
lock may not release with the wheels turned
off center. If this happens, the vehicle may
not start. Move the steering wheel from left
to right while attempting to start the
vehicle. If this does not work, the vehicle
needs service.
ON/RUN/START (Green Indicator Light) : This
mode is for driving and starting. With the
vehicle off, and the brake pedal applied,
pressing ENGINE START/STOP button once
will turn the ignition on. Once engine
cranking begins, release the button. Engine
cranking will continue until the engine
starts. See Starting the Engine 0 213.
4. Come to a complete stop, shift to
P (Park), and make sure engine is off.
The shift lever must be in P (Park) to
turn the vehicle off.
5. Set the parking brake. See Electric
Parking Brake 0 236.
Service Mode
Unless an emergency exists, do not turn the
engine off when the vehicle is moving. This
will cause a loss of power assist in the brake
and steering systems and disable the
airbags.

This power mode is available for service and
diagnostics, and to verify the proper
operation of the malfunction indicator lamp

Service Mode. Press the ENGINE START/STOP
button again to turn the vehicle off.
Starting Procedure
1. The remote key must be in the vehicle.
Press ENGINE START/STOP with the brake
pedal applied. When the engine begins
cranking, let go of the button.
Starting the Engine
If the vehicle has a diesel engine, see the
Duramax diesel supplement.
The driver may observe a minor, and
temporary, brake pedal kickback when
starting the vehicle. This is normal.
2. If the engine does not start after five to
10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor and holding it there while
pressing ENGINE START/STOP for up to a
maximum of 15 seconds. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the button
and accelerator. If the vehicle starts
briefly but then stops again, do the
same thing. This clears the extra gasoline
from the engine. Do not race the engine
immediately after starting it. Operate
the engine and transmission gently until
the oil warms up and lubricates all
moving parts.
Caution
The idle speed will go down as the
engine gets warm. Do not race the
engine immediately after starting it.
Operate the engine and transmission
gently to allow the oil to warm up and
lubricate all moving parts.
If you add electrical parts or accessories,
you could change the way the engine
operates. Any resulting damage would
not be covered by the vehicle warranty.
See Add-On Electrical Equipment 0 328.
When the low fuel warning light is on
and the FUEL LEVEL LOW message is
displayed in the Driver Information
Center (DIC), press ENGINE START/STOP
to continue engine cranking.
Move the shift lever to P (Park) or
N (Neutral). To restart the engine when the
vehicle is already moving, use
N (Neutral) only.
Caution
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could
damage the transmission. Shift to P (Park)
only when the vehicle is stopped.
Cranking the engine for long periods of
time, by returning the ignition to the
START position immediately after
cranking has ended, can overheat and
damage the cranking motor, and drain
