Windshield Washer
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
LQ(Washer Fluid):There is a paddle marked
with the windshield washer symbol at the top of
the multifunction lever. Push the paddle to spray
washer uid on the windshield. The wipers will clear
the window and then either stop or return to the
preset speed.
_(Heated Washer Fluid):If your vehicle has the
heated windshield washer uid system, it is used
to help clear ice, snow, tree sap, or bugs from your
windshield.To activate Automatic mode for de-icing, press the
heated washer button located to the left of the
steering wheel below the instrument panel brightness
control knob. Pushing the heated washer uid button
activates the heated windshield washer uid system.
This activation will initiate four heated wash/wipe cycles.
The rst heated wash/wipe cycle may take up to
40 seconds to occur, depending on outside temperature.
After the rst wash/wipe cycle, it may take up to
20 seconds for each of the remaining cycles. The heated
windshield washer uid system may be turned off at
any time by pushing the button again prior to the
completion of 4 wash/wipe cycles.
When the heated windshield washer uid system is
activated under certain outside temperature conditions,
steam may ow out of the washer nozzles for a short
period of time before washer uid is sprayed. This is
a normal condition. A message will be displayed on
the Driver Information Center (DIC) when the washer
uid is low. SeeDIC Warnings and Messages on
page 3-56.
3-10

Cruise Control
{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.
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained 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).
When you apply your brakes, cruise control is turned off.If your vehicle has the StabiliTrak
®system or Traction
Control system (TCS) and begins to limit wheel spin
while you are using cruise control, the cruise control will
automatically disengage. SeeStabiliTrak
®System on
page 4-7orTraction Control System (TCS) on page 4-5.
When road conditions allow you to safely use it again,
you can turn the cruise control back on.
The cruise control buttons
are located on the left side
of the steering wheel.
T(On/Off):This button can both activate and turn
off the system. The indicator light on the button turns
on when cruise control is on and turns off when
cruise control is off.
3-12

+ RES (Resume/Accelerate):Press this button to
make the vehicle accelerate or resume to a previously
set speed.
SET−(Set/Coast):Press this button to set the speed
or make the vehicle decelerate.
[(Cancel):Press this button to cancel cruise control
without erasing the set speed from memory.
Setting Cruise Control
Cruise control will not work if your parking brake is set
or if the master cylinder brake uid level is low.
The cruise control light on the instrument panel cluster
will come on after the cruise control has been set to
the desired speed.
{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. Press the cruise control On/Off button.
2. Get up to the desired speed.
3. Press the SET−button located on the steering
wheel and release it.
4. Take your foot off the accelerator.
3-13

Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This shuts off
the cruise control. But you do not need to reset it.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on the steering wheel.
The vehicle will return to the previously set speed
and stay there.
Increasing Speed While Using
Cruise Control
To increase the cruise speed while using cruise control:
Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
To increase vehicle speed in small increments,
press the +RES button. Each time this is done,
the vehicle will go about 1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
To reduce the vehicle’s speed while using
cruise control:
Press and hold the SET– button on the
steering wheel until the desired lower
speed is reached, then release it.
To slow down in very small amounts,
press the SET– button on the steering
wheel briey. Each time this is done, the
vehicle will go about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle’s
speed. When you take your foot off the pedal,
the vehicle will slow down to the previously set
cruise speed.
