Leaving the Vehicle with the
Engine Running
{WARNING
It can be dangerous to leave the
vehicle with the engine running.
It could overheat and catch fire.
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).
SeeShifting Into Park on
page 9‑19. If you are towing a
trailer, see Driving Characteristics
and Towing Tips on page 9‑47. If you have to leave the vehicle with
the engine running, be sure the
vehicle is in P (Park) and the
parking brake is firmly set. After the
shift lever is moved into P (Park),
hold the regular brake pedal down.
Then, see if you can move the shift
lever away from P (Park) without
first pulling it toward you. If you can,
it means that the shift lever was not
fully locked into P (Park).
Torque Lock
If you are parking on a hill and you
do not shift the transmission into
P (Park) properly, the weight of the
vehicle can put too much force on
the parking pawl in the
transmission. It might be difficult to
pull the shift lever out of P (Park).
This is called torque lock. To
prevent torque lock, set the parking
brake and then shift into P (Park)
properly before you leave the driver
seat. To find out how, see
Shifting
Into Park on page 9‑19. When you are ready to drive, move
the shift lever out of P (Park) before
releasing the parking brake.
If torque lock does occur, you might
need to have another vehicle push
yours a little uphill to take some of
the pressure from the parking pawl
in the transmission. Then you
should be able to pull the shift lever
out of P (Park).
Shifting out of Park
The vehicle has an automatic
transmission shift lock control
system. You have to fully apply the
brakes before you can shift from
P (Park) when the ignition is in ON/
RUN or ACC/ACCESSORY. See
Automatic Transmission (Six Speed)
on page 9‑22
orAutomatic
Transmission (Four Speed) on
page 9‑26.
The shift lock control system is
designed to do the following:
.Prevent the ignition key from
being removed unless the shift
lever is in P (Park).

WARNING (CONTINUED)
.There are holes or openings
in the vehicle body from
damage or aftermarket
modifications that are not
completely sealed.
If unusual fumes are detected or
if it is suspected that exhaust is
coming into the vehicle:
.Drive it only with the windows
completely down.
.Have the vehicle repaired
immediately.
Never park the vehicle with the
engine running in an enclosed
area such as a garage or a
building that has no fresh air
ventilation.
Running the Vehicle
While Parked
It is better not to park with the
engine running.
If the vehicle is left with the engine
running, follow the proper steps to
be sure the vehicle will not move.
See Shifting Into Park on page 9‑19
and Engine Exhaust on page 9‑21.
If parking on a hill and pulling a
trailer, see Driving Characteristics
and Towing Tips on page 9‑47.
Automatic
Transmission
Automatic Transmission
(Six Speed)
Vehicles with a six speed automatic
transmission have a shift position
indicator within the instrument
cluster.
There are several different positions
for the shift lever.
See “Range Selection Mode” under
Manual Mode on page 9‑28.
P (Park): This position locks the
rear wheels. It is the best position to
use when starting the engine
because the vehicle cannot move
easily. When parked on a hill,

Black plate (24,1)Chevrolet Express Owner Manual - 2013 - 1stPrintReady - 6/19/12
9-24 Driving and Operating
.Going about 55 km/h (35 mph) or
more, push the accelerator all
the way down.
By doing this, the vehicle shifts
down to the next gear and has
more power.
D (Drive) can be used when towing
a trailer, carrying a heavy load or
driving on steep hills. You might
want to shift the transmission to a
lower gear selection if the
transmission shifts too often.
Downshifting the transmission in
slippery road conditions could result
in skidding. See “Skidding”under
Loss of Control on page 9‑5.
The vehicle has a shift stabilization
feature that adjusts the transmission
shifting to the current driving
conditions in order to reduce rapid
upshifts and downshifts. This shift
stabilization feature is designed to
determine, before making an
upshift, if the engine is able to
maintain vehicle speed by analyzing
things such as vehicle speed,
throttle position, and vehicle load. If the shift stabilization feature
determines that a current vehicle
speed cannot be maintained, the
transmission does not upshift and
instead holds the current gear.
In some cases, this could appear to
be a delayed shift, however the
transmission is operating normally.
The transmission uses adaptive
shift controls. Adaptive shift controls
continually compares key shift
parameters to pre-programmed
ideal shifts stored in the
transmissions computer. The
transmission constantly makes
adjustments to improve vehicle
performance according to how the
vehicle is being used, such as with
a heavy load or when temperature
changes. During this adaptive shift
control process, shifting might feel
different as the transmission
determines the best settings.
The shift quality of a new vehicle
may not be ideal because the
Adaptive Shift Control process may
not have determined the best
settings for a particular shift or
condition. Shift quality will improve
with continued driving.
When temperatures are very cold,
the transmission's gear shifting
could be delayed providing more
stable shifts until the engine warms
up. Shifts could be more noticeable
with a cold transmission. This
difference in shifting is normal.
M (Manual Mode):
This position
lets drivers select the range of gears
appropriate for current driving
conditions. If the vehicle has this
feature, see “Range Selection
Mode” underManual Mode on
page 9‑28.
3 (Third): This position is also used
for normal driving. It reduces vehicle
speed more than D (Drive) without
using the brakes. You might choose
3 (Third) instead of D (Drive) when
driving on hilly, winding roads, when
towing a trailer, so there is less
shifting between gears and when

Driving and Operating 9-27
{WARNING
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
You could lose control and hit
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Notice: Shifting out of P (Park) or
N (Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle. D (Drive):
This position is for
normal driving. It provides the best
fuel economy. If you need more
power for passing, and you are:
.Going less than about 55 km/h
(35 mph), push the accelerator
pedal about halfway down.
.Going about 55 km/h (35 mph) or
more, push the accelerator all
the way down.
You will shift down to the next
gear and have more power.
Downshifting the transmission in
slippery road conditions could result
in skidding. See “Skidding”under
Loss of Control on page 9‑5.
3 (Third): This position is also used
for normal driving. However it
reduces vehicle speed more than
D (Drive) without using the brakes.
You might choose 3 (Third) instead
of D (Drive) when driving on hilly,
winding roads, when towing a trailer,
so there is less shifting between
gears and when going down a
steep hill. You should use 3 (Third) (or a lower
gear as needed) when towing a
trailer to minimize heat build-up and
extend the life of the transmission.
2 (Second):
This position reduces
vehicle speed even more than
3 (Third) without using the brakes.
You can use 2 (Second) on hills.
It can help control vehicle speed as
you go down steep mountain roads,
but then you would also want to use
the brakes off and on.
You may use this feature for
reducing torque to the rear wheels
when you are trying to start the
vehicle from a stop on slippery road
surfaces.
1 (First): This position reduces
vehicle speed even more than
2 (Second) without using the brakes.
You can use it on very steep hills,
or in deep snow or mud. If the shift
lever is put in 1 (First) while the
vehicle is moving forward, the
transmission will not shift into first
gear until the vehicle is going slowly
enough.

9-28 Driving and Operating
Notice:Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
Manual Mode
Range Selection Mode
The vehicle may have a Range
Selection Mode. The Range
Selection Mode helps control the
vehicle's transmission and vehicle
speed while driving down hill or
towing a trailer by letting you select
a desired range of gears. To use this feature:
1. Move the shift lever to
M (Manual Mode).
2. Press the +/− buttons on the
shift lever, to select the desired
range of gears for current driving
conditions.
When M (Manual Mode) is selected
a number displays in the DIC next to
the M indicating the current gear.
This number is the highest gear that
can be used. However, the vehicle
can automatically shift to lower
gears as it adjusts to driving
conditions. This means that all
gears below that number are
available. When 5 (Fifth) is selected,
1 (First) through 5 (Fifth) gears are
automatically shifted by the vehicle,
but 6 (Sixth) cannot be used until
the +/− button located on the
steering column lever is used to
change to the gear.
Grade Braking is not available when
Range Selection Mode is active.
See Tow/Haul Mode on page 9‑29. While using Range Selection Mode,
Cruise Control and the Tow/Haul
Mode can be used.
Notice:
Spinning the tires or
holding the vehicle in one place
on a hill using only the
accelerator pedal may damage
the transmission. The repair will
not be covered by the vehicle
warranty. If you are stuck, do not
spin the tires. When stopping on
a hill, use the brakes to hold the
vehicle in place.
Low Traction Mode
Low Traction Mode can assist in
vehicle acceleration when road
conditions are slippery. While the
vehicle is at a stop, select the
second gear range using Range
Selection Mode. This will limit
torque to the wheels after it detects
wheel slip, preventing the tires from
spinning.

suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.
Parking Brake
To set the parking brake, hold the
regular brake pedal, then push
down the parking brake pedal.
If the ignition is on, the brake
system warning light will come on.To release the parking brake, hold
the regular brake pedal down. Pull
the handle, located just above the
parking brake pedal, with the
parking brake symbol, to release the
parking brake.
If the ignition is on when the parking
brake is released, the brake system
warning light will go off.
Notice:
Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Verify that the parking
brake is fully released and the
brake warning light is off before
driving.
If you are towing a trailer and are
parking on a hill, see Driving
Characteristics and Towing Tips on
page 9‑47.

Driving Characteristics
and Towing Tips
Driving with a Trailer
When towing a trailer:
.Become familiar with the state
and local laws that apply to
trailer towing.
.Do not tow a trailer during the
first 800 km (500 mi) to prevent
damage to the engine, axle,
or other parts.
.Then during the first 800 km
(500 mi) of trailer towing, do not
drive over 80 km/h (50 mph) and
do not make starts at full throttle.
.Vehicles 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.
{WARNING
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the
liftgate, trunk/hatch, or rear-most
window is open.
When towing a trailer:
.Do not drive with the liftgate,
trunk/hatch, or rear-most
window open.
(Continued)
WARNING (CONTINUED)
.Fully open the air outlets on
or under the instrument
panel.
.Also adjust the Climate
Control system to a setting
that brings in only outside air.
See“Climate Control System”
in the Index.

Carbon Monoxide, see Engine
Exhaust on page 9‑21.
Towing a trailer requires a certain
amount of experience. The
combination you are driving is
longer and not as responsive as the
vehicle itself. Get acquainted with
the handling and braking of the rig
before setting out for the open road.
Before starting, check all trailer hitch
parts and attachments, safety
chains, electrical connectors, lamps,
tires, and mirrors. If the trailer has
electric brakes, start the
