Warning (Continued)
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering. Always have the
engine running and the vehicle
in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills;
something could be in your lane
(e.g., stalled car, accident). .
Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0177.
. The Antilock Brake System
(ABS) improves vehicle stability
during hard stops, but the
brakes should be applied sooner than when on dry pavement.
See
Antilock Brake System
(ABS) 0175.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0299. To get
help and keep everyone in the
vehicle safe:
. Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.

174 Driving and Operating
Operating Modes
The transmission may operate in a
lower gear than normal to improve
vehicle performance. The engine
speed may be higher and there may
be an increase in noise during the
following conditions:
.When climbing a grade.
. When driving downhill.
. When driving in hot
temperatures or at high altitude.
Manual Mode
Electronic Range Select
(ERS) Mode
ERS or manual mode allows for the
selection of the range of gear
positions. Use this mode when
driving downhill or towing a trailer to
limit the top gear and vehicle speed.
The shift position indicator within the
Driver Information Center (DIC) will
display a number next to the M
indicating the highest available gear
under manual mode and the driving
conditions when manual mode was
selected. To use this feature:
1. Move the shift lever to M (Manual Mode).
2. Press the plus/minus button on the shift lever, to increase or
decrease the gear range
available.
When shifting to M (Manual Mode),
the transmission will shift to a preset
lower gear range. For this preset
range, the highest gear available is
displayed next to the M in the DIC.
See Driver Information Center (DIC)
0 115 for more information. All gears
below that number are available to
use. For example, when 4 (Fourth)
is shown next to the M, 1 (First)
through 4 (Fourth) gears are shifted
automatically. To shift to 5 (Fifth)
gear, press the + (Plus) button or
shift into D (Drive).
M (Manual Mode) will prevent
shifting to a lower gear range if the
engine speed is too high. If vehicle
speed is not reduced within the time
allowed, the lower gear range shift
will not be completed. Slow the vehicle, then press the
−(Minus)
button to the desired lower gear
range.
While using the ERS, cruise control
can be used.
Fuel Economy Mode
Vehicles with a 2.4L engine have a
Fuel Economy Mode. When
engaged, Fuel Economy Mode can
improve the vehicle's fuel economy.

178 Driving and Operating
vehicle wheel brakes to assist the
driver in keeping the vehicle on the
intended path.
If cruise control is being used and
traction control or StabiliTrak begins
to limit wheel spin, cruise control will
disengage. Cruise control may be
turned back on when road
conditions allow.
Both systems come on
automatically when the vehicle is
started and begins to move. The
systems may be heard or felt while
they are operating or while
performing diagnostic checks. This
is normal and does not mean there
is a problem with the vehicle.
It is recommended to leave both
systems on for normal driving
conditions, but it may be necessary
to turn TCS off if the vehicle gets
stuck in sand, mud, ice, or snow.
SeeIf the Vehicle Is Stuck 0160
and “Turning the Systems Off and
On” later in this section.
The indicator light for both systems
is in the instrument cluster. This
light will:
.
Flash when TCS is limiting
wheel spin.
. Flash when StabiliTrak is
activated.
. Turn on and stay on when either
system is not working.
If either system fails to turn on or
to activate, a message displays in
the Driver Information Center (DIC),
and
dcomes on and stays on to
indicate that the system is inactive
and is not assisting the driver in
maintaining control. The vehicle is
safe to drive, but driving should be
adjusted accordingly. If
dcomes on and stays on:
1. Stop the vehicle.
2. Turn the engine off and wait 15 seconds.
3. Start the engine.
Drive the vehicle. If
dcomes on
and stays on, the vehicle may need
more time to diagnose the problem.
If the condition persists, see your
dealer.
Turning the Systems Off

Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
cruise control on winding roads or
in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If equipped with the StabiliTrak
®
system, the system may begin to
limit wheel spin while you are using
cruise control. If this happens, the
cruise control will automatically

briefly. For each press, the
vehicle goes about 1.6 km/h
(1 mph) faster.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster 0102.
The increment value used depends
on the units displayed.
Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
. Move the thumbwheel toward
SET/− and hold until the desired
lower speed is reached, then
release it.
. To decrease the vehicle speed in
small increments, move the

Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the previously
set cruise control speed. While
pressing the accelerator pedal or
shortly following the release to
override cruise control, briefly
moving the thumbwheel toward
SET/−
will result in cruise set to the
current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
speed, load, and the steepness of
the hills. When going up steep hills,
you might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied, the cruise control is
disengaged. Ending Cruise Control
There are four ways to end cruise
control:
.
Step lightly on the brake pedal.
. Press
n.
. Shift the transmission to
N (Neutral).
. To turn off cruise control,
press

Warning (Continued)
animals, signs, guardrails,
bridges, construction barrels,
or other objects. Be ready to take
action and apply the brakes. See
Defensive Driving0150.
FCA can be disabled with the FCA
steering wheel control.
Detecting the Vehicle Ahead
FCA warnings will not occur unless
the FCA system detects a vehicle
ahead. When a vehicle is detected,
the vehicle ahead indicator will
display green. Vehicles may not be
detected on curves, highway exit
ramps, or hills, due to poor visibility;
or if a vehicle ahead is partially
blocked by pedestrians or other objects. FCA will not detect another
vehicle ahead until it is completely
in the driving lane.
{Warning
FCA does not provide a warning
to help avoid a crash, unless it
detects a vehicle. FCA may not
detect a vehicle ahead if the FCA
sensor is blocked by dirt, snow,
or ice, or if the windshield is
damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
When your vehicle approaches
another detected vehicle too rapidly,
the red FCA display will flash and
sound several high-pitched beeps
from the front. When this Collision
Alert occurs, the brake system may
prepare for driver braking to occur
more rapidly which can cause a
brief, mild deceleration. Continue to
apply the brake pedal as needed.
Cruise control may be disengaged
when the Collision Alert occurs.
Tailgating Alert
The red Collision Alert display will
stay continuously illuminated when
following a detected vehicle ahead
much too closely.
