Kickdown Mode
If equipped, the accelerator pedalprovides an additional downshiftafter pressing through the kickdownfeature.
It requires extra pedal pressure nearthe end of its travel to engage.
Manual Mode
Range Selection Mode
If equipped, Range Selection Modehelps control the vehicle'stransmission and vehicle speedwhile driving downhill or towing atrailer by letting you select a desiredrange of gears.
To u s e t h i s f e a t u r e :
1. Move the shift lever toL(ManualMode).
2. Press the plus/minus buttonson the shift lever to select thedesired range of gears forcurrent driving conditions.
With an 8-speed automatictransmission, hold the plus/minusbuttons on the shift lever to selectthe highest or lowest rangeavailable for the current vehiclespeed.
When the shift lever is moved fromD(Drive) to L(Manual Mode), anumber displays next to the L,indicating the current transmissionrange.
This number is the highest gear thatthe transmission will command whileoperating in L (Manual Mode). Allgears below that number areavailable. As driving conditionschange, the transmission canautomatically shift to lower gears.For example, when L5 is selected,1(First) through 5(Fifth) gears areautomatically shifted by thetransmission, but 6 (Sixth) cannot beused until the plus/minus button onthe shift lever is used to change tothe range.

282 Driving and Operating
If the vehicle has an exhaust brake,it can also be used, but will notautomatically downshift thetransmission. See“Exhaust Brake”in the Duramax diesel supplement.
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 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
If equipped, Low Traction Modeassists in vehicle acceleration whenroad conditions are slippery, suchas with ice or snow. While thevehicle is at a stop, select L2 usingRange Selection Mode. This willlimit torque to the wheels and helpto prevent the tires from spinning.
Tow/Haul Mode
Vehicles with an automatictransmission have a Tow/HaulMode. The Tow/Haul Mode adjuststhe transmission shift pattern toreduce shift cycling. This providesincreased performance, vehiclecontrol, and enhanced transmissionand engine cooling when drivingdown steep hills or mountaingrades, when towing, or whenhauling heavy loads.
The selector button is on the end ofthe shift lever. Turn the Tow/HaulMode on and off by pressing the
button. When the Tow/Haul Mode isenabled, a light on the instrumentcluster will come on.
For an eAssist vehicle, the Stop/Start function will becomeunavailable when Tow/Haul Mode isactive.
For an eAssist vehicle, theRegenerative Braking functionality isdisabled when using the Tow/HaulMode. See the eAssist supplement.

Shift Speeds
{Warning
If you skip a gear when
downshifting, you could lose
control of the vehicle. You could
injure yourself or others. Do not
shift down more than one gear at
atimewhendownshifting.
Drive Systems
Four-Wheel Drive
If equipped, four-wheel driveengages the front axle for extratraction. Read the appropriatesection for transfer case operationbefore using.
Caution
Do not drive on clean, dry
pavement in 4mand 4n(if
equipped) for an extended period
of time. These conditions may
cause premature wear on the
vehicle’spowertrain.
Driving on clean, dry pavement in4HI or 4LO may:
.Cause a vibration to be felt inthe steering system.
.Cause tires to wear faster.
.Make the transfer case harder toshift, and cause it to run noisier.

.Shift in one continuous motion.
.Shifting while the vehicle is inmotion may require thatmoderate force be applied to the
shift lever before 4mcan be
engaged, especially in coldweather.
.In extremely cold weather, it maybe necessary to slow or stop thevehicle to shift.
.While in 4m,thevehiclecanbe
driven at any posted legal speedlimit.
Shifting In or Out of 4n
Caution
Shifting the transfer case into 4n
while moving at speeds faster
than 5 km/h (3 mph) may cause
premature wear to the transfer
case, and may cause the gears to
grind.
1. If possible, shift with thevehicle moving 5 km/h (3 mph)or less.
2. Shift the transmission intoN(Neutral).
3. Shift the transfer case shiftlever in one continuous motion.
4. Shifting with the vehicle at astop may be more difficult. It ispossible that the shift will notcomplete and the transfer casewill remain in N (Neutral). Thisis normal. To complete theshift, with the engine running,shift the transmission to
D(Drive) and back toN(Neutral), and reattempt thetransfer case shift.
Shifting In or Out of N (Neutral)
1. Have the engine running.
