DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and down-
shifts, and the best fuel economy. The transmission
automatically upshifts through all forward gears. The
DRIVE position provides optimum driving characteris-
tics under all normal operating conditions.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading condi-
tions, in hilly terrain, traveling into strong head winds, or
while towing a heavy trailer), select TOW mode (refer to
“Selec-Track” in “Starting And Operating”) or use the
AutoStick shift control (refer to “AutoStick” in this
section for further information) to select a lower gear.
Under these conditions, using TOW mode or a lower
gear will improve performance and extend transmission
life by reducing excessive shifting and heat buildup.During extremely cold temperatures (-22°F [-30°C] or
below), transmission operation may be modified depend-
ing on engine and transmission temperature as well as
vehicle speed. Normal operation will resume once the
transmission temperature has risen to a suitable level.
MANUAL (M)
The MANUAL (M, +/-) position (beside the DRIVE
position) enables full manual control of transmission
shifting (also known as AutoStick mode; refer to
“AutoStick” in this section for further information). Tog-
gling the gear selector forward (-) or rearward (+) while
in the MANUAL (AutoStick) position will manually
select the transmission gear, and will display the current
gear in the instrument cluster.

When To Use TOW Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting oc-
curs, select TOW mode, using the rotary switch on the
center console. Selecting TOW mode will improve per-
formance and reduce the potential for transmission over-
heating or failure due to excessive shifting. Refer to
“Selec-Track” in “Starting And Operating” for further
information.
AUTOSTICK
AutoStick is a driver-interactive transmission feature
providing manual shift control, giving you more control
of the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This system
can also provide you with more control during passing,
city driving, cold slippery conditions, mountain driving,
trailer towing, and many other situations.
Operation
To activate AutoStick mode, move the shift lever into the
MANUAL (M) position (beside the DRIVE position), or
tap one of the shift paddles on the steering wheel.
Tapping the (-) shift paddle to enter AutoStick mode will
downshift the transmission to the next lower gear, while
tapping (+) to enter AutoStick mode will retain the
current gear. The current transmission gear will be dis-
played in the instrument cluster. In AutoStick mode, you
can use the shift lever (in the MANUAL position), or the
shift paddles, to manually shift the transmission. Tapping
the shift lever forward (-) while in the MANUAL (M)
position, or tapping the (-) shift paddle on the steering
wheel, will downshift the transmission to the next lower
gear. Tapping the lever rearward (+) (or tapping the (+)
shift paddle) will command an upshift.
NOTE:The shift paddles may be disabled (or re-enabled,
as desired) using Drive Modes.

WARNING!
•If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there may
not be enough brake pressure to hold both the
vehicle and the trailer on a hill when the brake
pedal is released. In order to avoid rolling down an

tivate the trailer brake or apply more vehicle brake
pressure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
• Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.

This feature can be turned on or turned off. To change the
current setting, proceed as follows:
506 STARTING AND OPERATING

Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle’s speed
are sufficient to potentially cause wheel lift, it then
applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM can only reduce the chance of wheel lift
occurring during severe or evasive driving maneuvers; it
cannot prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, or striking objects
or other vehicles.
NOTE:ERM is disabled anytime the ESC is in “Full Off”
mode (if equipped). Refer to “Electronic Stability Control
(ESC)” in this section for a complete explanation of the
available ESC modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. ERM cannot
prevent all wheel lift or roll overs, especially those
that involve leaving the roadway or striking objects
or other vehicles. The capabilities of an ERM-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize the
user’s safety or the safety of others.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. TSC will become
active automatically once an excessively swaying trailer
is recognized. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
5
STARTING AND OPERATING 513

follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in this section for further informa-
tion.
When TSC is functioning, the “ESC Activation/
Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being
applied to individual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC system is in
the “Partial Off” or “Full Off” modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time required to
reach full braking during emergency braking situations.It anticipates when an emergency braking situation may
occur by monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake system for a
panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking performance
in wet conditions. It will periodically apply a small
amount of brake pressure to remove any water buildup
on the front brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When Rain Brake
Support is active, there is no notification to the driver and
no driver interaction is required.
Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the ESC and EPS
modules that provides torque at the steering wheel for
certain driving conditions in which the ESC module is
detecting vehicle instability. The torque that the steering
wheel receives is only meant to help the driver realize

3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, andspare tires.
Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle. You
will not exceed the tire’s load carrying capacity if you
adhere to the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire and Loading
Information placard in “Vehicle Loading” in the “Starting
And Operating” section of this manual.
NOTE: Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and rear
axles must not be exceeded. For further information on
GAWRs, vehicle loading, and trailer towing, refer to
“Vehicle Loading” in the “Starting And Operating” sec-
tion of this manual. To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX lbs or
XXX kg” on the Tire and Loading Information placard.
The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never exceed
the weight referenced here.
Steps For Determining Correct Load Limit
1. Locate the statement “The combined weight of occu-
pants and cargo should never exceed XXX lbs or
XXX kg” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and pas- sengers from XXX lbs or XXX kg.
530 STARTING AND OPERATING

4. The resulting figure equals the available amount ofcargo and luggage load capacity. For example, if
“XXX” amount equals 1,400 lbs (635 kg) and there will
be five 150 lb (68 kg) passengers in your vehicle, the
amount of available cargo and luggage load capacity
is 650 lbs (294 kg) (since 5 x 150 lbs (68 kg) = 750 lbs
(340 kg), and 1400 lbs (635 kg) – 750 lbs (340 kg) =
650 lbs [294 kg]).
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not
safely exceed the available cargo and luggage load
capacity calculated in step 4. NOTE:
•
If your vehicle will be towing a trailer, load from your
trailer will be transferred to your vehicle. The follow-
ing table shows examples on how to calculate total
load, cargo/luggage, and towing capacities of your
vehicle with varying seating configurations and num-
ber and size of occupants. This table is for illustration
purposes only and may not be accurate for the seating
and load carry capacity of your vehicle.
• For the following example, the combined weight of
occupants and cargo should never exceed 865 lbs
(392 kg).

NOTE:The premium Tire Pressure Monitor System will
automatically locate the pressure values displayed in the
correct vehicle position following a tire rotation.
The suggested rotation method is the “rearward-cross”
shown in the following diagram.TIRE PRESSURE MONITOR SYSTEM (TPMS)
NOTE: For vehicles equipped with run flat tires — When
the TPMS indicates a tire pressure of 14 psi (96 kPa) or
lower, always check tire pressure and replace the tire at
the first opportunity. At inflation pressure of/or below 14
psi (96 kPa) the tire is in the run-flat mode of operation.
In this condition, it is recommended a vehicle maximum
speed of 50 mph (80 km/h) for a maximum distance of 50
miles (80 km). The manufacturer does not recommend
using the run flat feature while driving a vehicle loaded
at full capacity or towing a trailer.
The Tire Pressure Monitoring System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about 1
psi (7 kPa) for every 12°F (6.5°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
