252STARTING AND OPERATING
Automatic Transmission
Select the DRIVE (D) range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions, will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine
braking.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate
performance and avoids frequent down -
shifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Reduce
vehicle speed as necessary to avoid
extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi -
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission
overheating, take the following actions:
City Driving
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
engine idle speed. Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
SNOW PLOW
Snow plows, winches, and other aftermarket
equipment should
not be added to the front end
of your vehicle. The airbag crash sensors may
be affected by the change in the front end
structure. The airbags could deploy
unexpectedly or could fail to deploy during a
collision.
WARNING!
Do not add a snow plow, winches, or any
other aftermarket equipment to the front of
your vehicle. This could adversely affect the
functioning of the airbag system and you
could be injured.

NOTE:
Your vehicle may be transmitting data as
authorized by the subscriber.
Once a connection is made between the
vehicle’s SOS Call system and the SOS oper -
ator, the SOS operator may be able to open a
voice connection with the vehicle to deter -
mine if additional assistance is needed. Once
the SOS operator opens a voice connection
with the vehicle’s SOS Call system, the oper -
ator should be able to speak with you or other
vehicle occupants and hear sounds occurring
in the vehicle. The vehicle’s SOS Call system will attempt to
remain connected with the SOS operator
until the SOS operator terminates the
connection.
5. The SOS operator may attempt to contact appropriate emergency responders and
provide them with important vehicle
information and GPS coordinates.
WARNING!
ALWAYS obey traffic laws and pay attention to
the road. ALWAYS drive safely with your hands
on the steering wheel. You have full
responsibility and assume all risks related to
the use of the features and applications in
this vehicle. Only use the features and
applications when it is safe to do so. Failure
to do so may result in an accident involving
serious injury or death.
WARNING!
If anyone in the vehicle could be in danger
(e.g., fire or smoke is visible, dangerous
road conditions or location), do not wait for
voice contact from an Emergency Services
Agent. All occupants should exit the vehicle
immediately and move to a safe location.
Never place anything on or near the
vehicle’s operable network and GPS
antennas. You could prevent operable
network and GPS signal reception, which
can prevent your vehicle from placing an
emergency call. An operable network and
GPS signal reception is required for the SOS
Call system to function properly.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add
aftermarket electrical equipment to the
vehicle’s electrical system. This may
prevent your vehicle from sending a signal
to initiate an emergency call. To avoid inter -
ference that can cause the SOS Call system
to fail, never add aftermarket equipment
(e.g., two-way mobile radio, CB radio, data
recorder, etc.) to your vehicle’s electrical
system or modify the antennas on your
vehicle. IF YOUR VEHICLE LOSES BATTERY
POWER FOR ANY REASON (INCLUDING
DURING OR AFTER AN ACCIDENT), THE
UCONNECT FEATURES, APPS AND
SERVICES, AMONG OTHERS, WILL NOT
OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to
fail when you need it. You could be injured
if the air bag system is not there to help
protect you.

IN CASE OF EMERGENCY287
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the trans -
mission in NEUTRAL (N), but do not increase
the engine idle speed while preventing
vehicle motion with the brakes.
NOTE:
There are steps that you can take to slow down
an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
You can also turn the temperature control to
maximum heat, the mode control to floor and
the blower control to high. This allows the
heater core to act as a supplement to the
radiator and aids in removing heat from the
engine cooling system.
MANUAL PARK RELEASE
To move the vehicle in cases where the
transmission will not shift out of PARK (P) (such
as a depleted battery), a Manual Park Release
is available.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam coming
from under the hood, do not open the hood
until the radiator has had time to cool. Never
try to open a cooling system pressure cap
when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately and
call for service.
WARNING!
Always secure your vehicle by fully applying
the parking brake before activating the
Manual Park Release. In addition, you should
be seated in the driver’s seat with your foot
firmly on the brake pedal when activating the
Manual Park Release. Activating the Manual
Park Release will allow your vehicle to roll
away if it is not secured by the parking brake,
or by proper connection to a tow vehicle.
Activating the Manual Park Release on an
unsecured vehicle could lead to serious injury
or death for those in or around the vehicle.
