202 Driving and Operating
the engine starts, let go of the
accelerator. If the vehicle starts briefly
but then stops again, repeat these steps.
This clears the extra gasoline from the
engine.
Caution
Cranking the engine for long periods of
time, by returning the ignition to the
START position immediately after
cranking has ended, can overheat and
damage the cranking motor, and drain
the battery. Wait at least 15 seconds
between each try, to let the cranking
motor cool down.
Stopping the Engine
If the vehicle has an automatic transmission,
move the shift lever to P (Park) and press
and hold ENGINE START/STOP on the
instrument panel, until the engine shuts off.
If the shift lever is not in P (Park), the
engine shuts off and the ignition goes to
ACC/ACCESSORY. The DIC displays SHIFT TO
PARK. Once the shift lever is moved to
P (Park), the vehicle turns off.
If the vehicle has a manual transmission,
before getting out of the vehicle, shift to
1 (First) or R (Reverse) and apply the parkingbrake. Then turn off the ignition off by
pressing ENGINE START/STOP and release
the clutch pedal when the engine has
stopped.
If the RKE transmitter is not detected inside
the vehicle when it is turned off the DIC
displays a message.
Engine Heater
{Warning
Do not plug in the engine block heater
while the vehicle is parked in a garage or
under a carport. Property damage or
personal injury may result. Always park
the vehicle in a clear open area away
from buildings or structures.
If equipped, the engine heater can help in
cold weather conditions at or below −18 °C
(0 °F) for easier starting and better fuel
economy during engine warm-up. Plug in
the coolant heater at least four hours before
starting the vehicle. An internal thermostat
in the plug end of the cord will prevent
engine heater operation at temperatures
above −18 °C (0 °F).
Using the Engine Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord.
The electrical cord is on the passenger
side of the engine compartment, next to
the engine compartment fuse block.
Check the heater cord for damage. If it is
damaged, do not use it. See your dealer
for a replacement. Inspect the cord for
damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.

Driving and Operating 211
To stop, let up on the accelerator pedal and
press the brake pedal. Just before the
vehicle stops, press the clutch pedal and the
brake pedal, and shift to Neutral.
Neutral :Use this position when starting or
idling the engine. The shift lever is in
Neutral when it is centered in the shift
pattern, not in any gear.
R : To back up, press the clutch pedal to the
floor and shift into R (Reverse). Let up on
the clutch pedal slowly while pressing the
accelerator pedal.
One to Four Shift Message (V8 Only)
When this message comes on, the vehicle
can only be shifted from 1 (First) to
4 (Fourth) instead of 1 (First) to 2 (Second).
The message will display in the Driver
Information Center (DIC).
Complete the shift into 4 (Fourth) to turn off
this feature. This helps to get the best
possible fuel economy.
After shifting to 4 (Fourth), downshift to a
lower gear, if desired.
Caution
Forcing the shift lever into any gear
except 4 (Fourth) when the 1-4 SHIFT
message comes on may damage the
transmission. Shift only from 1 (First) to
4 (Fourth) when the message comes on.
This message will come on when:
.The engine coolant temperature is higher
than 76 °C (169 °F).
.The vehicle is accelerating from a stop
and going 24 to 31 km/h (15 to 19 mph).
.The vehicle is at 33% throttle or less.
Once displayed, the message will remain in
the DIC for two seconds, even if the
conditions for skip shift are no longer
satisfied. Vehicles equipped with a Head-Up Display
(HUD) may also have performance shift
timing lights across the top of the display.
The rows of lights get closer together as the
maximum shift point gets closer. Shift the
transmission before the lights come together
in the display. Shift immediately if the lights
are flashing.
See
Head-Up Display (HUD) 0100.
Active Rev Match
Vehicles equipped with a V8 engine and a
manual transmission have Active Rev Match
(ARM). ARM aids in smoother shifting by
matching the engine speed to the next
selected gear. By monitoring shift lever and
clutch operation, ARM adjusts engine speed
to match a calibrated value based on gear
selection. On upshifts and downshifts,
engine speed will be decreased and
increased to match vehicle road speed and
transmission gear position. ARM is
maintained while the clutch pedal is pressed,
but will deactivate if the shift lever is left in
the Neutral position.

212 Driving and Operating
The system is activated and deactivated by
pressing either of the paddles marked REV
MATCH on the steering wheel. The system
must be activated with each new ignition
cycle.
A gear indicator in the instrument cluster
displays the current gear selected:
.When ARM is activated, the gear number
is amber.
.When ARM is deactivated, the gear
number is white.
.If no gear number is displayed while the
shift lever is in gear, service is required.
ARM will be disabled, and the malfunctionindicator lamp will be on. See
Malfunction
Indicator Lamp 091. The clutch and
manual transmission will continue to
operate normally.
ARM will also:
.Only be active above 25 km/h (16 mph).
.Only match engine speed up to
5400 rpm.
.Not operate when the accelerator pedal is
applied.
.Be disabled when the coolant
temperature is below 0 °C (32 °F).
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. See Antilock Brake System
(ABS) Warning Light 094.
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.

{Warning
An underhood electric fan can start up
even when the engine is not running and
can cause injury. Keep hands, clothing,
and tools away from any underhood
electric fan.
{Warning
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The cooling system in the vehicle is filled
with DEX-COOL engine coolant. See
Maintenance Schedule 0304 and
Recommended Fluids and Lubricants 0313.
The following explains the cooling system
and how to check and add coolant when it
is low. If there is a problem with engine
overheating, see Engine Overheating 0252.
What to Use
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or
the wrong mixture, the engine could get
(Continued)
Warning (Continued)
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
Use a 50/50 mixture of clean drinkable
water and DEX-COOL coolant. This mixture:
.Gives freezing protection down to −37 °C
(−34 °F), outside temperature
.Gives boiling protection up to 129 °C
(265 °F), engine temperature
.Protects against rust and corrosion
.Will not damage aluminum parts
.Helps keep the proper engine
temperature
Caution
Do not use anything other than a mix of
DEX-COOL coolant that meets GM
Standard GMW3420 and clean, drinkable
water. Anything else can cause damage
to the engine cooling system and the
vehicle, which would not be covered by
the vehicle warranty.
Never dispose of engine coolant by putting
it in the trash, pouring it on the ground,
or into sewers, streams, or bodies of water.
