Turn and Lane-Change Signals
G:An arrow on the instrument cluster
flashes in the direction of the turn or lane
change.
To signal a turn, move the lever all the way
up or down.
To signal a lane change, raise or lower the
lever until the arrow starts to flash. The
turn signal automatically flashes three times
and if the Tow/Haul Mode is active it
flashes six times. Holding the turn signal
lever for more than one second causes the
turn signals to flash continually until the
lever is released. The lever returns to its starting position
when released.
If after signaling a turn or lane change the
arrow flashes rapidly or does not come on, a
signal bulb may be burned out.
Have any burned out bulbs replaced. If a
bulb is not burned out, check the fuse. See
Fuses and Circuit Breakers
0205.Turn Signal On Chime
If the turn signal is left on for more than
1.2 km (0.75 mi), a chime sounds at each
flash of the turn signal and the message
TURN SIGNAL ON also appears in the Driver
Information Center (DIC). To turn off the
chime and message, move the turn signal
lever to the off position.

The exterior lamps and dome lamp remain
on after the door is closed for a set amount
of time, then automatically turn off.
The exterior lamps turn off immediately by
turning the exterior lamp control off. The
exit lighting for exterior lights can be
changed. SeeVehicle Personalization 086.
Battery Load Management
The vehicle may have Electric Power
Management (EPM) that estimates the
battery's temperature and state of charge.
It then adjusts the voltage for best
performance and extended life of the
battery.
When the battery's state of charge is low,
the voltage is raised slightly to quickly bring
the charge back up. When the state of
charge is high, the voltage is lowered
slightly to prevent overcharging. If the
vehicle has a voltmeter gauge or a voltage
display on the Driver Information Center
(DIC), you may see the voltage move up or
down. This is normal. If there is a problem,
an alert will be displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for
all vehicles. This is because the generator (alternator) may not be spinning fast
enough at idle to produce all the power that
is needed for very high electrical loads.
A high electrical load occurs when several of
the following are on, such as: headlamps,
high beams, fog lamps, rear window
defogger, climate control fan at high speed,
heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory
power outlets.
EPM works to prevent excessive discharge of
the battery. It does this by balancing the
generator's output and the vehicle's
electrical needs. It can increase engine idle
speed to generate more power, whenever
needed. It can temporarily reduce the power
demands of some accessories.
Normally, these actions occur in steps or
levels, without being noticeable. In rare
cases at the highest levels of corrective
action, this action may be noticeable to the
driver. If so, a Driver Information Center
(DIC) message might be displayed, such as
SERVICE BATTERY CHARGING SYSTEM. If this
messages displays, it is recommended that
the driver reduce the electrical loads as
much as possible.
Battery Power Protection
This feature shuts off the interior lamps if
they are left on for more than 10 minutes
when the ignition is off. This helps to
prevent the battery from running down.
Exterior Lighting Battery Saver
The exterior lamps turn off about 10 minutes
after the ignition is turned off, if the parking
lamps or headlamps have been manually
left on. This protects against draining the
battery. To restart the 10-minute timer, turn
the exterior lamp control to the
Oposition
and then back to the
;or2position.
To keep the lamps on for more than
10 minutes, the ignition must be on or in
ACC/ACCESSORY.

144 Driving and Operating
constantly makes adjustments to improve
vehicle performance according to how the
vehicle is being used, such as with a heavy
load or when the temperature changes.
During this adaptive shift control process,
shifting might feel different as the
transmission determines the best settings.
The shift quality of a new vehicle may not
be ideal because the adaptive shift control
process may not have determined the best
settings for a particular shift or condition.
Shift quality will improve with continued
driving.
When temperatures are very cold, the
transmission's gear shifting could be
delayed, providing more stable shifts until
the engine warms up. Shifts could be more
noticeable with a cold transmission. This
difference in shifting is normal.
M :This position lets drivers select the
range of gears appropriate for current
driving conditions. If the vehicle has this
feature, see “Range Selection Mode” under
Manual Mode 0144.
1 : This position reduces vehicle speed
without using the brakes. You can use it for
major/severe downgrades where the vehicle
would otherwise accelerate due to steepness
of grade. When you shift to 1 (First) it provides the lowest gear appropriate to
current road speed and continues to
downshift as the vehicle slows, eventually
downshifting to 1 (First) gear. The
transmission can be held in 1 (First) gear
using Range Selection Mode or the shift
lever. See
“Range Selection Mode” under
Manual Mode 0144.
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 the
vehicle is stuck, do not spin the tires.
When stopping on a hill, use the brakes
to hold the vehicle in place.
Normal Mode Grade Braking
This mode is enabled when the vehicle is
started, but is not enabled in Range
Selection Mode. It assists in maintaining
desired vehicle speeds when driving on
downhill grades by using the engine and
transmission to slow the vehicle. The first
time the system activates for each ignition
key cycle. To disable or enable Normal Mode Grade
Braking within the current ignition key cycle,
press and hold the Tow/Haul button for
three seconds.
For other forms of grade braking, see
Tow/
Haul Mode 0145 and
Cruise Control 0149.
Manual Mode
Range Selection Mode
If equipped, Range Selection Mode helps
control the vehicle's transmission and vehicle
speed while driving downhill or towing a
trailer by letting you select a desired range
of gears.
To use this feature:
1. Move the shift lever to M (Manual Mode).
2. Press the +/− buttons on the shift lever
to select the desired range of gears for
current driving conditions.

146 Driving and Operating
Brakes
Antilock Brake System (ABS)
The Antilock Brake System (ABS) helps
prevent a braking skid and maintain steering
while braking hard.
ABS performs a system check when the
vehicle is first driven. A momentary motor
or clicking noise may be heard while this
test is going on, and the brake pedal may
move slightly. This is normal.
If there is a problem with ABS, this warning
light stays on. SeeAntilock Brake System
(ABS) Warning Light 078.
ABS does not change the time needed to
get a foot on the brake pedal and does not
always decrease stopping distance. If you
get too close to the vehicle ahead, there will
not be enough time to apply the brakes if
that vehicle suddenly slows or stops. Always
leave enough room ahead to stop, even
with ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down firmly. Hearing or feeling ABS
operate is normal.
Braking in Emergencies
ABS allows steering and braking at the same
time. In many emergencies, steering can
help even more than braking.
Parking Brake
To set the parking brake: 1. Hold the regular brake pedal down.
2. Firmly push the parking brake pedal down. 3. The brake system warning light will
come on, if the ignition is on. See Brake
System Warning Light 077.
If you are towing a trailer and parking on a
hill, see Driving Characteristics and Towing
Tips 0160.
To release the parking brake: 1. Hold the regular brake pedal down.
2. Pull the handle with the parking brake symbol located just above the parking
brake pedal.
3. The brake system warning light will turn off, if the ignition is on.
Caution
Driving with the parking brake on can
overheat the brake system and cause
premature wear or damage to brake
system parts. Make sure that the parking
brake is fully released and the brake
warning light is off before driving.
Driving with the parking brake applied will
cause a warning chime to sound and a
Driver Information Center (DIC) message
may display. Release the parking brake or
stop the vehicle.
