Not all manual downshift requests will be allowed
by the transmission. To prevent excessive
engine RPMs, each gear has a maximum vehicle
speed associated with it. Any downshift request
above this speed is not allowed by the
transmission.
If shifting is prevented for any reason, the current
gear ashes multiple times in the Driver
Information Center (DIC), indicating that the
transmission has not shifted gears.
Some automatic downshifts can occur to maintain
minimum engine speed. This only happens if the
vehicle is left in too high of a gear for the vehicle’s
speed. For example, if you have been driving in
sixth gear range and come to a stop without
manually downshifting, the transmission
automatically downshifts to rst gear and displays
rst gear on the HUD. As you begin to drive and
accelerate, the transmission remains in rst gear
until the driver selects a downshift.DSC can be used while using cruise control, but
transmission shifting is different while the
cruise control is on. This is not a malfunction and
is necessary to let proper operation of the
cruise control.
To return to fully automatic operation, move the
shift lever to the right and back into DRIVE (D).
When accelerating your vehicle from a stop
in snowy and icy conditions, you may want to shift
into second gear. A higher gear lets you gain
more traction on slippery surfaces.
In higher gears, on the XLR only, an automatic
downshift occurs if you press the accelerator pedal
to the oor. This feature provides adequate
acceleration capabilities if you forget to downshift
manually. Tap the shifter forward and the
vehicle upshifts.

Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions
allow you to signal a turn or a lane change.
To signal a turn, move the multifunction lever all
the way up or down. When the turn is nished, the
lever will return automatically.
An arrow on the
instrument panel cluster
will ash in the
direction of the turn or
lane change.To signal a lane change, just raise or lower the
lever until the arrow starts to ash. Hold it
there until you complete your lane change. The
lever will return by itself when you release it.
If you signal a turn or a lane change and
the arrows ash faster than normal, a signal bulb
may be burned out. Other drivers will not see
the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. If the arrows do not go on at all
when you signal a turn, check the fuses and check
for burned-out bulbs. SeeFuses and Circuit
Breakers on page 453.
Turn Signal on Chime
A chime will remind you if you leave the turn
signal on for more than 3/4 mile (1.2 km) of driving.
If you need to leave the turn signal on for more
than 3/4 mile (1.2 km), turn off the signal and then
turn it back on.
142
Cruise Control
Your vehicle has cruise control.
9(Off):This position
turns the system off.
R(On):This position turns the system on.
+ (Resume/Accelerate):This position makes the
vehicle accelerate or resume to a previously
set speed.
T(Set):Press this button at the end of the
lever to set the speed.
With cruise control, you can maintain a speed of
about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can
really help on long trips. Cruise control does not
work at speeds below about 25 mph (40 km/h).Cruise control will not work if the parking brake is
set, or if the master cylinder brake uid level is low.
{CAUTION:
Cruise control can be dangerous where
you cannot drive safely at a steady speed.
So, do not use your 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 your vehicle has the traction control system and
it begins to limit wheel spin while cruise control
is on, the cruise control will automatically
disengage. SeeTraction Control System (TCS) on
page 329. When road conditions allow you to
safely use it again, you may turn cruise control
back on.
147
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do
not want to. You could be startled and
even lose control. Keep the cruise control
switch off until you want to use cruise
control.
1. Move the cruise control switch to on.
2. Get up to the speed desired.
3. Press the set button at the end of the lever
and release it.
4. Take your foot off the accelerator pedal.The cruise symbol on
the instrument panel
cluster will be lit
when the cruise control
is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This
disengages the cruise control. But it does not
need to be reset.
Once you are going about 25 mph (40 km/h) or
more, you can move the cruise control switch
brie y from on to resume/accelerate.
You will go right back up to your chosen speed
and stay there.
If you hold the switch at resume/accelerate the
vehicle will keep going faster until you release the
switch or apply the brake. Do not hold the
switch at resume/accelerate, unless you want the
vehicle to go faster.
148
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the
lever, then release the button and the
accelerator pedal. You will now cruise at the
higher speed. If the accelerator pedal is
held longer than 60 seconds, cruise control
will turn off.
Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the
desired speed, and then release the switch. To
increase your speed in very small amounts,
move the switch brie y to resume/accelerate.
Each time you do this, your vehicle will go
about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
Press and hold the set button until you reach
the lower speed desired, then release it.
To slow down in very small amounts, brie y
press the set button. Each time you do this,
your vehicle will go about 1 mph (1.6 km/h)
slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your
vehicle will slow down to the cruise control speed
you set earlier.
149
Using Cruise Control on Hills
How well your cruise control works on hills
depends upon your speed, load and the steepness
of the hills. When going up steep hills, you
might have to step on the accelerator pedal to
maintain your speed. When going downhill,
you might have to brake or shift to a lower gear to
keep your vehicle’s speed down. Of course,
applying the brake turns off the cruise control.
Many drivers nd this to be too much trouble and
do not use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal
Move the cruise control switch to off
Erasing Speed Memory
Turning off the cruise control or the ignition, will
erase your cruise control set speed memory.
