STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts. Start the engine with the gear selector in the
NEUTRAL or PARK position. Apply the brake
before shifting to any driving range.
Normal Starting

1. Do not press the accelerator.

2. Use the fob with Integrated Key to briefly turn the ignition switch to the START
position and release it as soon as the
starter engages. The starter motor will
continue to run, and it will disengage
automatically when the engine is running.
3. If the engine fails to start, the starter will disengage automatically in 10 seconds. If
this occurs, turn the ignition switch to the
OFF position, wait 10 to 15 seconds, then
repeat the “Normal Starting” procedure
(Steps 1–3 above).
NOTE:
This vehicle is equipped with a transmission
shift interlocking system. The brake pedal must
be pressed to shift out of PARK.
WARNING!
When exiting the vehicle, always remove
the key fob from the vehicle and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the transmission gear
selector.
Do not leave the key fob in or near the
vehicle, or in a location accessible to chil-
dren, and do not leave the ignition in the
ACC or ON/RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.

Cold Weather Operation
(Below –22°F Or −30°C)
To ensure reliable starting at these
temperatures, use of an externally powered
electric engine block heater (available from an
authorized dealer) is recommended.
After Starting — Warming Up The Engine
The idle speed is controlled automatically and it
will decrease as the engine warms up.
If Engine Fails To Start ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and
permits quicker starts in cold weather. Connect
the cord to a standard 110-115 Volt AC
electrical outlet with a grounded, three-wire
extension cord.
The engine block heater must be plugged in at
least one hour to have an adequate warming
effect on the engine.
The engine block heater cord is routed under
the hood on the driver's side of the vehicle. It
has a removable cap that is located on the
driver side of the Integrated Power Module.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle) in
your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
While cruising, brief full-throttle acceleration
within the limits of local traffic laws contributes
to a good break-in. Wide-open throttle
acceleration in low gear can be detrimental and
should be avoided.
WARNING!
Never pour fuel or other flammable liquid
into the throttle body air inlet opening in an
attempt to start the vehicle. This could
result in flash fire causing serious personal
injury.
Do not attempt to push or tow your vehicle
to get it started. Vehicles equipped with an
automatic transmission cannot be started
this way. Unburned fuel could enter the
catalytic converter and once the engine has
started, ignite and damage the converter
and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a
start from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly. Refer to
“Jump Starting Procedure” in “In Case Of
Emergency” for further information.
WARNING! (Continued)WARNING!
Remember to disconnect the engine block
heater cord before driving. Damage to the
110-115 Volt electrical cord could cause
electrocution.

164STARTING AND OPERATING
The engine oil installed in the engine at the
factory is a high-quality energy conserving type
lubricant. Oil changes should be consistent with
anticipated climate conditions under which
vehicle operations will occur. For the
recommended viscosity and quality grades,
refer to “Dealer Service” in “Servicing And
Maintenance”.
NOTE:
A new engine may consume some oil during its
first few thousand miles (kilometers) of
operation. This should be considered a normal
part of the break-in and not interpreted as a
problem.
PARK BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK position. The foot operated parking brake is positioned
below the lower left corner of the instrument
panel. To apply the park brake, firmly push the
park brake pedal fully. To release the parking
brake, press the park brake pedal a second
time and let your foot up as you feel the brake
disengage.

Parking Brake

When the parking brake is applied with the
ignition switch in the ON position, the “Brake
Warning Light” in the instrument cluster will
illuminate. NOTE:
When the parking brake is applied and the
automatic transmission is placed in gear, the
“Brake Warning Light” will flash. If vehicle
speed is detected, a chime will sound to alert
the driver. Fully release the parking brake
before attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application.
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill
grade and away from the curb on an uphill
grade. For vehicles equipped with an automatic
transmission, apply the parking brake before
placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism
may make it difficult to move the gear selector
out of PARK. The parking brake should always
be applied whenever the driver is not in the
vehicle.CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

AUTOMATIC TRANSMISSIONWARNING!
When exiting the vehicle, always remove
the key fob from the ignition and lock your
vehicle.
Never leave children alone in a vehicle, or
with access to an unlocked vehicle.
Allowing children to be in a vehicle unat
-
tended is dangerous for a number of
reasons. A child or others could be seriously
or fatally injured. Children should be
warned not to touch the parking brake,
brake pedal or the gear selector.
Do not leave the key fob in or near the
vehicle (or in a location accessible to chil -
dren), and do not leave the ignition in the
ACC or ON/ RUN mode. A child could
operate power windows, other controls, or
move the vehicle.
Be sure the parking brake is fully disen -
gaged before driving; failure to do so can
lead to brake failure and a collision.
Always fully apply the parking brake when
leaving your vehicle, or it may roll and
cause damage or injury. Also be certain to
leave the transmission in PARK. Failure to
do so may allow the vehicle to roll and
cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on
with the parking brake released, a brake
system malfunction is indicated. Have the
brake system serviced by an authorized
dealer immediately.
WARNING! (Continued)
WARNING!
It is dangerous to shift out of PARK or
NEUTRAL if the engine speed is higher than
idle speed. If your foot is not firmly pressing
the brake pedal, the vehicle could accel -
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and your
foot is firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As with
all vehicles, you should never exit a vehicle
while the engine is running. Before exiting a
vehicle, always come to a complete stop,
then apply the parking brake, shift the
transmission into PARK, turn the engine
OFF, and remove the key fob. When the
ignition is in the LOCK/OFF (key removal)
position, the transmission is locked in
PARK, securing the vehicle against
unwanted movement.

STARTING AND OPERATING167
Fuel Economy (ECON) Mode
The Fuel Economy (ECON) mode can improve
the vehicle's overall fuel economy during
normal driving conditions. Push the “econ”
switch in the center stack of the instrument
panel and a green light will indicate the ECON
mode is engaged.

Fuel Economy Mode Switch

When the Fuel Economy (ECON) Mode is
enabled, the vehicle control systems will
change the following:
The transmission will upshift sooner and
downshift later.
The transmission will skip select gears during
shifts to allow the engine to operate at lower
speeds.
The torque converter clutch may engage at
lower engine speeds and remain on longer.
The engine idle speed will be lower.
The overall driving performance will be more
conservative.
Some ECON mode functions may be tempo -
rarily inhibited based on temperature and
other factors.
Six-Speed Automatic Transmission
The transmission gear position display (located
in the instrument cluster) indicates the
transmission gear range. You must press the
brake pedal to move the gear selector out of
PARK refer to “Brake/Transmission Shift
Interlock System” in this section. To drive, move
the gear selector from PARK or NEUTRAL to the
DRIVE position.
The electronically-controlled transmission
provides a precise shift schedule. The
transmission electronics are self-calibrating;
therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal
condition, and precision shifts will develop
within a few hundred miles (kilometers).
Gear Selector

Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and the
vehicle is stopped. Be sure to keep your foot on
the brake pedal when shifting between these
gears.
The transmission gear selector has only PARK,
REVERSE, NEUTRAL, and DRIVE shift positions.
Manual downshifts can be made using the
Electronic Range Select (ERS) shift control refer
to “Electronic Range Select (ERS) Operation” in
this section for further information. Moving the
gear selector to the left or right (–/+) while in
the DRIVE position will select the highest
available transmission gear, and will display
that gear in the instrument cluster as 1, 2, 3,
etc.5

20_RT_OM_EN_USC_t.book Page 167

170STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and
highway driving. It provides the smoothest
upshifts and downshifts, and the best fuel
economy. The transmission automatically
upshifts through all forward gears. The DRIVE
position provides optimum driving character -
istics under all normal operating conditions.
When frequent transmission shifting occurs
(such as when operating the vehicle under
heavy loading conditions, in hilly terrain,
traveling into strong head winds, or while towing
a heavy trailer), use the Electronic Range Select
(ERS) shift control refer to "Electronic Range
Select (ERS) Operation" in this section for
further information to select a lower gear range.
Under these conditions, using a lower gear range will improve performance and extend
transmission life by reducing excessive shifting
and heat buildup.
During cold temperatures, transmission
operation may be modified depending on
engine and transmission temperature as well
as vehicle speed. This feature improves warm
up time of the engine and transmission to
achieve maximum efficiency. Engagement of
the torque converter clutch is inhibited until the
transmission fluid is warm refer to the “Note”
under “Torque Converter Clutch” in this section.
During extremely cold temperatures (-16°F
[-27°C] or below), operation may briefly be
limited to third gear only. Normal operation will
resume once the transmission temperature has
risen to a suitable level.
Transmission Limp Home Mode
Transmission function is monitored electron
-
ically for abnormal conditions. If a condition is
detected that could result in transmission
damage, Transmission Limp Home Mode is
activated. In this mode, the transmission
remains in THIRD gear regardless of which
forward gear is selected. PARK, REVERSE, and
NEUTRAL will continue to operate. The
Malfunction Indicator Light (MIL) may be illuminated. Limp Home Mode allows the
vehicle to be driven to an authorized dealer for
service without damaging the transmission.
In the event of a momentary problem, the
transmission can be reset to regain all forward
gears by performing the following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.
3. Turn the ignition OFF.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the
problem is no longer detected, the
transmission will return to normal
operation.
NOTE:
Even if the transmission can be reset, we
recommend that you visit an authorized dealer
at your earliest possible convenience. An
authorized dealer has diagnostic equipment to
assess the condition of your transmission.
If the transmission cannot be reset, authorized
dealer service is required.
CAUTION!
Towing the vehicle, coasting, or driving for any
other reason with the transmission in
NEUTRAL can cause severe transmission
damage. Refer to “Recreational Towing” in
“Starting And Operating” and “Towing A
Disabled Vehicle” in “What To Do In
Emergencies” for further information.

20_RT_OM_EN_USC_t.book Page 170

STARTING AND OPERATING171
Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control
allows the driver to limit the highest available
gear when the transmission is in DRIVE. For
example, if you set the transmission gear limit
to 4 (FOURTH gear), the transmission will not
shift above FOURTH gear (except to prevent
engine overspeed), but will shift through the
lower gears normally.
You can switch between DRIVE and ERS mode
at any vehicle speed. When the gear selector is in the DRIVE position, the transmission will
operate automatically, shifting between all
available gears. Tapping the gear selector to the
left (-) will activate ERS mode, display the
current gear in the instrument cluster, and set
that gear as the top available gear. Once in ERS
mode, tapping the gear selector to the left (-) or
right (+) will change the top available gear.
To exit ERS mode, simply hold the gear selector
to the right (+) until the gear limit display
disappears from the instrument cluster.
NOTE:
To select the proper gear position for maximum deceleration (engine braking), tap the gear selector to the left (-) repeatedly as the vehicle slows. The
transmission will shift to the range from which the vehicle can best be slowed down.WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the vehicle
could skid, causing a collision or personal
injury.

172STARTING AND OPERATING
Overdrive Operation
The automatic transmission includes an
electronically controlled Overdrive (SIXTH gear).
The transmission will automatically shift into
Overdrive if the following conditions are
present:
The gear selector is in the DRIVE position.
The transmission fluid has reached an
adequate temperature.
The engine coolant has reached an adequate
temperature.
The vehicle speed is sufficiently high.
The driver is not heavily pressing the
accelerator.
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic
transmission on your vehicle. A clutch within the
torque converter engages automatically at
calibrated speeds. This may result in a slightly
different feeling or response during normal
operation in the upper gears. When the vehicle
speed drops or during some accelerations, the
clutch automatically disengages. NOTE:
The torque converter clutch will not engage until
the transmission fluid and engine coolant are
warm [usually after 1 to 3 miles (2 to 5 km) of
driving]. Because the engine speed is higher
when the torque converter clutch is not
engaged, it may seem as if the transmission is
not shifting into Overdrive when cold. This is
normal. Using the Electronic Range Select (ERS)
shift control, when the transmission is
sufficiently warm, will demonstrate that the
transmission is able to shift into and out of
Overdrive.
POWER STEERING
The standard Power Steering system will give
you good vehicle response and increased ease
of maneuverability in tight spaces. The system
will provide mechanical steering capability if
power assist is lost.
If for some reason the power assist is
interrupted, it will still be possible to steer your
vehicle. Under these conditions, you will
observe a substantial increase in steering
effort, especially at very low vehicle speeds and
during parking maneuvers.
NOTE:
Increased noise levels at the end of the
steering wheel travel are considered normal
and do not indicate that there is a problem
with the power steering system.
Upon initial start-up in cold weather, the
power steering pump may make noise for a
short amount of time. This is due to the cold,
thick fluid in the steering system. This noise
should be considered normal, and it does not
in any way damage the steering system.
CAUTION!
Prolonged operation of the steering system at
the end of the steering wheel travel will
increase the steering fluid temperature and it
should be avoided when possible. Damage to
the power steering pump may occur.

Trailer Towing Weights (Maximum Trailer Weight Ratings)
The following chart provides the maximum trailer weight ratings towable for your given drivetrain:
NOTE:
The trailer tongue weight must be considered as
part of the combined weight of occupants and
cargo, and should never exceed the weight
referenced on the Tire and Loading Information
placard. Refer to “Tire Safety Information” in
“Servicing and Maintenance” for further
information.
Trailer And Tongue Weight
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.

*Refer to local laws for maximum trailer towing speeds.
CAUTION!
Always load a trailer with 60% of the weight in
the front of the trailer. This places 10% of the
GTW on the tow hitch of your vehicle. Loads
balanced over the wheels or heavier in the
rear can cause the trailer to sway severely
side to side which will cause loss of control of
the vehicle and trailer. Failure to load trailers
heavier in front is the cause of many trailer
collisions.

190STARTING AND OPERATING
Automatic Transmission
The DRIVE range can be selected when towing.
However, if frequent shifting occurs while in
DRIVE, use the Electronic Range Select (ERS)
shift control to manually select a lower gear
range.
NOTE:
Using a lower gear range 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.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then
change the transmission fluid and filter as
specified for "police, taxi, fleet, or frequent
trailer towing." Refer to the “Maintenance Plan”
for the proper maintenance intervals. Electronic Range Select (ERS)When using the ERS shift control, select the
highest gear that allows for adequate perfor
-
mance and avoids frequent downshifts. For
example, choose “4” if the desired speed can
be maintained. Choose “3” or “2” 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 range 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, but do not increase
engine idle speed.
Highway Driving
Reduce speed.
Temporarily turn off air conditioning.
