136 Driving and Operating
{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, turn off the
vehicle only in an emergency.
In an emergency, if the vehicle cannot be
pulled over and must be turned off while
driving: 1. Push the key all the way in toward the steering column, then turn the key to
ACC/ACCESSORY.
2. Brake using firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
3. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
Continue braking and steer the vehicle to
a safe location.
4. Come to a complete stop.
5. Shift to P (Park).
6. Continue to hold the brake pedal, then set the parking brake. See Parking Brake
0 146. 7. Push the key all the way in toward the
steering column, then turn the ignition
to LOCK/OFF.
8. Remove the key.
9. Release the brake pedal.
Caution
Use the correct key, make sure it is all
the way in —or pushed all the way in
toward the steering column when turning
off the vehicle —and turn it only with
your hand.
1 (ACC/ACCESSORY) : This position allows
features such as the infotainment system to
operate while the vehicle is off. It also
unlocks the steering column, if equipped
with a locking steering column. Use this
position if the vehicle must be pushed or
towed. See Retained Accessory Power (RAP)
0 138.
From ON/RUN, push the key all the way in
toward the steering column, then turn the
key to ACC/ACCESSORY.
If the key is left in ACC/ACCESSORY with the
engine off, the battery could drain and the
vehicle may not start. A warning chime will sound when the driver
door is opened and the key is in the
ignition.
2 (ON/RUN) :
This position can be used to
operate the electrical accessories and to
display some instrument cluster warning
and indicator lights. This position can also
be used for service and diagnostics, and to
verify the proper operation of the
malfunction indicator lamp as may be
required for emission inspection purposes.
The switch stays in this position when the
engine is running. The transmission is also
unlocked in this position.
If the key is left in ON/RUN with the engine
off, the battery could drain and the vehicle
may not start.
3 (START) : This is the position that starts
the engine. When the engine starts, release
the key. The ignition returns to ON/RUN for
driving.
Starting the Engine
If the vehicle has a diesel engine, see the
Duramax diesel supplement.
To place the transmission in the
proper gear:

GMC Savana Owner Manual (GMNA-Localizing-U.S./Canada-14583543) -

Driving and Operating 137
Move the shift lever to P (Park) or
N (Neutral). The engine will not start in any
other position. To restart the engine when
the vehicle is already moving, use
N (Neutral) only.
Caution
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.
SeeAdd-On Electrical Equipment 0176.
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.
Caution
If the steering wheel is turned until it
reaches the end of its travel, and is held
in that position while starting the vehicle,
damage may occur to the hydraulic
power steering system and there may be
loss of power steering assist. Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition key to START. When
the engine starts, let go of the key. The
idle speed will go down as your 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.
When the low fuel warning light is on
and the FUEL LEVEL LOW message is
displayed in the Driver Information
Center (DIC), the Computer-Controlled
Cranking System is disabled to prevent
possible vehicle component damage.
When this happens, hold the ignition
switch in the START position to continue
engine cranking.
Caution
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
(Continued)
Caution (Continued)
the battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down.
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 as you
hold the key in START for up to
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 key 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.

Engine Coolant Heater
If the vehicle has a diesel engine, see the
Duramax diesel supplement.
{Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport. Property damage or
personal injury may result. Always park
the vehicle in a clear open area away
from buildings or structures.
The engine coolant heater can provide easier
starting and better fuel economy during
engine warm-up in cold weather conditions
at or below −18 °C (0 °F). Vehicles with an
engine coolant heater should be plugged in
at least four hours before starting.
An internal thermostat in the plug end of
the cord may exist which will prevent
engine coolant heater operation at
temperatures above −18 °C (0 °F).
To Use the Engine Coolant Heater
1. Turn off the engine.

Driving and Operating 143
Caution
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.
Caution
A transmission hot message may display
if the automatic transmission fluid is too
hot. Driving under this condition can
damage the vehicle. Stop and idle the
engine to cool the automatic
transmission fluid. This message clears
when the transmission fluid has cooled
sufficiently.
D : 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. 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” underLoss of Control 0128.
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
compare key shift parameters to pre-programmed ideal shifts stored in the
transmission’s 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 the 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 :
This position lets drivers select the
range of gears appropriate for current
driving conditions. If the vehicle has this
feature, see “Range Selection Mode” under
Manual Mode 0144.
1 : This position reduces vehicle speed
without using the brakes. You can use it for
major/severe downgrades where the vehicle

GMC Savana Owner Manual (GMNA-Localizing-U.S./Canada-14583543) -

144 Driving and Operating
would otherwise accelerate due to steepness
of grade. When you shift to 1 (First) it
provides the lowest gear appropriate to
current road speed and continues to
downshift as the vehicle slows, eventually
downshifting to 1 (First) gear. The
transmission can be held in 1 (First) gear
using Range Selection Mode or the shift
lever. See“Range Selection Mode” under
Manual Mode 0144.
Caution
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 the
vehicle is stuck, do not spin the tires.
When stopping on a hill, use the brakes
to hold the vehicle in place.
Normal Mode Grade Braking
This mode is enabled when the vehicle is
started, but is not enabled in Range
Selection Mode. It assists in maintaining
desired vehicle speeds when driving on
downhill grades by using the engine and transmission to slow the vehicle. The first
time the system activates for each ignition
key cycle.
To disable or enable Normal Mode Grade
Braking within the current ignition key cycle,
press and hold the Tow/Haul button for
three seconds.
For other forms of grade braking, see
Tow/
Haul Mode 0145 and
Cruise Control 0149.
Manual Mode
Range Selection Mode
If equipped, Range Selection Mode helps
control the vehicle's transmission and vehicle
speed while driving downhill 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, the
transmission will downshift and a number
displays in the Driver Information
Center (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 on the shift lever is used to change
to the gear.
Grade Braking is not available when Range
Selection Mode is active. See Tow/Haul
Mode 0145.
While using Range Selection Mode, cruise
control and the Tow/Haul Mode can
be used.

that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Parking Brake
To set the parking brake:1. Hold the regular brake pedal down. 2. Firmly push the parking brake
pedal down.
3. The brake system warning light will come on, if the ignition is on. See Brake
System Warning Light 077.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0160.
To release the parking brake: 1. Hold the regular brake pedal down.
2. Pull the handle with the parking brake symbol located just above the parking
brake pedal.
3. The brake system warning light will turn off, if the ignition is on.
Caution
Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake
system parts. Make sure that the parking
brake is fully released and the brake
warning light is off before driving. Driving with the parking brake applied will
cause a warning chime to sound and a
Driver Information Center (DIC) message
may display. Release the parking brake or
stop the vehicle.
Brake Assist
Brake Assist detects rapid brake pedal
applications due to emergency braking
situations and provides additional braking to
activate the Antilock Brake System (ABS) if
the brake pedal is not pushed hard enough
to activate ABS normally. Minor noise, brake
pedal pulsation, and/or pedal movement
during this time may occur. Continue to
apply the brake pedal as the driving
situation dictates. Brake Assist disengages
when the brake pedal is released.
Hill Start Assist (HSA)
{Warning
Do not rely on the HSA feature. HSA does
not replace the need to pay attention
and drive safely. You may not hear or
feel alerts or warnings provided by this
system. Failure to use proper care when
