138 Driving and Operating
To rock the vehicle back and forth to get
out of snow, ice, or sand without damaging
the transmission, seeIf the Vehicle Is Stuck
0 126.
N : In this position, the engine does not
connect with the wheels. To restart when
you are already moving, use N (Neutral)
only. Also, use N (Neutral) when the vehicle
is being towed.
{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.
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

Caution (Continued)
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 0123.
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

GMC Savana Owner Manual (GMNA-Localizing-U.S./Canada-15555961) -
2022 - CRC - 4/14/22
Driving and Operating 139
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 0139.
1 : This position reduces vehicle speed
without using the brakes. You can use it for
major/severe downgrades where the vehicle
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 0139.
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 0140 and
Cruise Control 0144.
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.

2022 - CRC - 4/14/22
140 Driving and Operating
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. SeeTow/Haul
Mode 0140.
While using Range Selection Mode, cruise
control and the Tow/Haul Mode can
be used.
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.
Tow/Haul Mode
If equipped, Tow/Haul Mode adjusts the
transmission shift pattern to reduce shift
cycling, providing increased performance,
vehicle control, and transmission cooling
when towing or hauling heavy loads. Turn the Tow/Haul Mode on and off by
pressing the button on the instrument
panel. When Tow/Haul is on, a light on the
instrument cluster will come on.
See
Tow/Haul Mode Light 079.

Tow/Haul Mode Grade Braking
Tow/Haul Mode Grade Braking is only
enabled while the Tow/Haul Mode is
selected and the vehicle is not in the Range
Selection Mode. See “Tow/Haul Mode”listed
previously and Manual Mode0139. Tow/
Haul Mode Grade Braking assists in
maintaining desired vehicle speeds when
driving on downhill grades by using the
engine and transmission to slow the vehicle.
To disable or enable Tow/Haul Mode Grade
Braking within the current ignition key cycle,
press and hold the Tow/Haul button for
three seconds.

188 Vehicle Care
If the overheat warning is displayed with no
sign of steam:1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan
speed. Open the windows as necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) and
let the engine idle.
If the engine coolant temperature gauge is
no longer in the overheat zone or an
overheat warning no longer displays, the
vehicle can be driven. Continue to drive the
vehicle slowly for about 10 minutes. Keep a
safe vehicle distance from the vehicle in
front. If the warning does not come back on,
continue to drive normally and have the
cooling system checked for proper fill and
function.
If the warning continues, pull over, stop, and
park the vehicle right away.
If there is still no sign of steam, push down
the accelerator until the engine speed is
about twice as fast as normal idle speed for
at least three minutes while parked. If the
warning is still on, turn off the engine until
it cools down. If the decision is made not to lift the hood,
get service help right away.
Engine Fan
The vehicle has a clutched engine cooling
fan. When the clutch is engaged, the fan
spins faster to provide more air to cool the
engine. In most everyday driving conditions,
the fan is spinning slower and the clutch is
not fully engaged. This improves fuel
economy and reduces fan noise. Under
heavy vehicle loading, trailer towing, and/or
high outside temperatures, the fan speed
increases as the clutch more fully engages,
so an increase in fan noise may be heard.
This is normal and should not be mistaken
as the transmission slipping or making extra
shifts. It is merely the cooling system
functioning properly. The fan will slow down
when additional cooling is not required and
the clutch partially disengages.
This fan noise may be heard when starting
the engine. It will go away as the fan clutch
partially disengages.
Power Steering Fluid
The power steering fluid reservoir is in the
engine compartment on the driver side of
the vehicle. See
Engine Compartment
Overview 0176 for reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power
steering fluid unless there is a leak
suspected in the system or an unusual noise
is heard. A fluid loss in this system could
indicate a problem. Have the system
inspected and repaired.
How to Check Power Steering Fluid
To check the power steering fluid:
1. Turn the key off and let the engine compartment cool down.
2. Wipe the cap and the top of the reservoir clean.
3. Unscrew the cap and wipe the dipstick with a clean rag.

.The TPMS sensor matching process was
not done or not completed successfully
after rotating the tires. The malfunction
light and the DIC message should go off
after successfully completing the sensor
matching process. See "TPMS Sensor
Matching Process" later in this section.
.One or more TPMS sensors are missing or
damaged. The malfunction light and the
DIC message should go off when the
TPMS sensors are installed and the sensor
matching process is performed
successfully. See your dealer for service.
.Replacement tires or wheels do not match
the original equipment tires or wheels.
Tires and wheels other than those
recommended could prevent the TPMS
from functioning properly. SeeBuying
New Tires 0217.
.Operating electronic devices or being near
facilities using radio wave frequencies
similar to the TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning properly, it
cannot detect or signal a low tire pressure
condition. See your dealer for service if the
TPMS malfunction light and DIC message
come on and stay on.
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification code
needs to be matched to a new tire/wheel
position after rotating the vehicle’s tires or
replacing one or more of the TPMS sensors.
Also, the TPMS sensor matching process
should be performed after replacing a spare
tire with a road tire containing the TPMS
sensor. The malfunction light and the DIC
message should go off at the next ignition
cycle. The sensors are matched to the tire/
wheel positions, using a TPMS relearn tool,
in the following order: driver side front tire,
passenger side front tire, passenger side rear
tire, and driver side rear. See your dealer for
service or to purchase a relearn tool.
A TPMS relearn tool can also be purchased.
See Tire Pressure Monitor Sensor Activation
Tool at www.gmtoolsandequipment.com or
call 1-800-GM TOOLS (1-800-468-6657).
There are two minutes to match the first
tire/wheel position, and five minutes overall
to match all four tire/wheel positions. If it
takes longer, the matching process stops
and must be restarted.
The TPMS sensor matching process is: 1. Set the parking brake. 2. Turn the ignition on without starting the
vehicle. See Ignition Positions 0130.
3. Press the Remote Keyless Entry (RKE) transmitter's
QandKbuttons at the
same time for approximately
five seconds. The horn sounds twice to
signal the receiver is in relearn mode
and TIRE LEARNING ACTIVE message
displays on the DIC screen.
If the vehicle does not have RKE, press
the Driver Information Center (DIC)
vehicle information button until the
PRESS VTO RELEARN TIRE POSITIONS
message displays. The horn sounds twice
to signal the receiver is in relearn mode
and TIRE LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall, near the valve stem. Then press
the button to activate the TPMS sensor.
A horn chirp confirms that the sensor
identification code has been matched to
this tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
