Cruise Control
With cruise control, a speed of
about 40 km/h (25 mph) or more
can be maintained without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. Do not use
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 equipped with a manual
transmission, the cruise control will
remain active when the gears are shifted. The cruise is disengaged if
the clutch is pressed for several
seconds.
If the Traction Control System (TCS)
begins to limit wheel spin while you
are using cruise control, the cruise
control automatically disengages.
See
Traction Control/Electronic
Stability Control on page 9-38.
When road conditions allow for
using safely again, cruise control
can be turned back on.
If the brakes are applied, cruise
control disengages.
1(On/Off): Press to turn cruise
control on or off. A white indicator
comes on in the instrument cluster
when cruise is turned on.
RES/+ (Resume/Accelerate): If
there is a set speed in memory,
press briefly to resume to that
speed or press and hold to
accelerate. If cruise control is
already active, use to increase
vehicle speed.
SET/– (Set/Coast): Press briefly to
set the speed and activate cruise
control. If cruise control is already
active, use to decrease vehicle
speed.
*(Cancel): Press to disengage
cruise control without erasing the
set speed from memory.

9-50 Driving and Operating
Setting Cruise Control
If the
1button is on when not in
use, SET/– or RES/+ could get
pressed and go into cruise when not
desired. Keep the
1button off
when cruise is not being used.
1. Press the
1button to turn the
cruise system on.
2. Get up to the desired speed.
3. Press and release the SET/– button on the steering wheel.
4. Remove foot from the accelerator.
The cruise control indicator on the
instrument cluster turns green after
cruise control has been set to the
desired speed. See Instrument
Cluster on page 5-7.
Resuming a Set Speed
If the cruise control is set at a
desired speed and then the brakes
are applied or
*is pressed, the
cruise control is disengaged without
erasing the set speed from memory. Once the vehicle reaches about
40 km/h (25 mph) or more, briefly
press the RES/+ button. The vehicle
returns to the previous set speed.
Increasing Speed While Using
Cruise Control
If the cruise control system is
already activated,
.Press and hold RES/+ until the
desired speed is reached, then
release it.
.To increase vehicle speed in
small increments, briefly press
RES/+. For each press, the
vehicle goes about 1.6 km/h
(1 mph) faster.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on
page 5-7. The increment value used
depends on the unites displayed. Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
.Press and hold SET/–
until the
desired lower speed is reached,
then release it.
.To decrease the vehicle speed in
small increments, briefly press
SET/–. For each press, the
vehicle goes about 1.6 km/h
(1 mph) slower.
The speedometer reading can be
displayed in either English or metric
units. See Instrument Cluster on
page 5-7. The increment value used
depends on the unites displayed.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle will slow down to the
previously set cruise speed.

Driving and Operating 9-51
While pressing the accelerator pedal
or shortly following the release to
override cruise control, briefly
pressing SET/–will result in cruise
set to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control works
on hills depends upon the vehicle
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 speed
down. If the brake pedal is applied,
cruise control will disengage.
Cruise Control in Manual Paddle
Shift Gear Selection
When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are not being used, cruise
control operates in the same
manner as D (Drive). When the vehicle is in M (Manual
Mode) and the manual paddle shift
controls are being used, cruise
control operates as follows:
.If cruise control is active and a
gear is selected with the manual
paddle shift controls, the vehicle
speed is maintained in the driver
selected gear and will not
automatically upshift or
downshift the transmission while
the driver
’s gear selection is
active.
.If driving in hilly terrain, cruise
control may not be able to
maintain vehicle speed if an
upshift or downshift is not
selected by the driver. While
driving on hilly terrain and cruise
control is active with a manual
paddle shift gear selection, the
driver must select the proper
gear for the terrain or select D
(Drive) on the gear range
selector for full automatic
transmission operation. Ending Cruise Control
.Step lightly on the brake pedal.
.If equipped with a manual
transmission, press the clutch
pedal for several seconds or
shift to Neutral to disengage
cruise control.
.Press*.
.To turn off cruise control,
press
1.
Erasing Speed Memory
The cruise control set speed is
erased from memory if
1is pressed
or if the ignition is turned off.

Also, seeAdding Equipment to the
Airbag-Equipped Vehicle on
page 3-25.Lifting the Vehicle
{Warning
Lifting a vehicle can cause an
injury. The vehicle can slip off the
jack and roll over you or other
people. You and they could be
badly injured. Find a level place
to lift your vehicle. To help
prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission in P (Park) or a
manual transmission in
1 (First) or R (Reverse).
3. Turn off the engine.
To be even more certain the
vehicle will not move, put blocks
in front of and behind the wheels.
{Warning
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack,
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle or the vehicle
may fall and cause injury to you
or others.
If a jack is used to lift the vehicle,
follow the instructions that came
with the jack, and be sure to use the
correct lifting points to avoid
damaging the vehicle.

Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10-18.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil (Except
Z51 and Z06)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away. See
Engine Oil Messages on page 5-37.
Check the engine oil level regularly.
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
on page 10-7 for the location of the
engine oil dipstick.
