Transporting Pets
Airbags deploying in the front seat could harm your pet.
An unrestrained pet will be thrown about and possibly
injured, or injure a passenger during panic braking or in
a collision. Pets should be restrained in the rear seat in
pet harnesses or pet carriers that are secured by seat belts.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine in
your new vehicle.
Drive moderately during the first 300 miles (500 km).
After the initial 60 miles (100 km), speeds up to 50 or 55
mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration, within the
limits of local traffic laws, contributes to a good break-in.
Wide open throttle acceleration in low gear can be
detrimental and should be avoided.The engine oil installed in the engine at the factory is a
high quality energy conserving type lubricant. Oil
changes should be consistent with anticipated climate
conditions under which vehicle operations will occur.
The recommended viscosity and quality grades are
shown in Section 7 of this manual. NON-DETERGENT
OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
A new engine may consume some oil during its first few
thousand miles (kilometers) of operation. This should be
considered as a normal part of the break-in and not
interpreted as an indication of difficulty.

SAFETY TIPS
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO) which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO)
follow the safety tips below.
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas which can kill.
Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for a extended period. If the vehicle isstopped in an open area with engine running for more
than a short period, adjust the ventilation system to
force fresh, outside air into the vehicle.
•Guard against carbon monoxide with proper mainte-
nance. Have the exhaust system inspected every time
the vehicle is raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with all side
windows fully open.
•Always run the climate control in panel or floor mode
when driving with any windows open, even if only
slightly, to help keep fresh air circulating inside ve-
hicle. Otherwise poisonous gases could be drawn into
the vehicle.
68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

This system performs two functions. With the engine
running and the multi-function control lever in the A
(Auto) position, the headlights will turn on and off based
on the surrounding light levels.
Headlights On Automatically With Wipers
If your vehicle is equipped with Automatic Headlights it
also has this customer programmable feature. When your
headlights are in the automatic mode, and the engine is
running, they will automatically turn on when the wiper
system is on.
If your vehicle is equipped with a “Rain Sensitive Wiper
System,” and it is activated, the headlights will automati-
cally turn on after the wipers complete five wipe cycles
within approximately 1 minute, and they will turn off
approximately four minutes after the wipers completely
stop. Refer to “Windshield Wipers and Washers” in this
section for more information.NOTE:When your headlights come on during the
daytime, the instrument panel lights will automatically
dim to the lower nighttime intensity. Refer to “Instru-
ment Panel and Interior Lights” below for setting the
instrument panel lights to full daytime intensity.SmartBeams — If Equipped
The SmartBeam system provides increased forward light-
ing at night by automating high beam control through
the use of a digital camera mounted on the inside
rearview mirror. This camera detects vehicle specific light
and automatically switches from high beams to low
beams until the approaching vehicle is out of view.
NOTE:If the windshield or SmartBeam mirror is re-
placed, the SmartBeam mirror must be re-aimed to
ensure proper performance. See your local authorized
dealer.

“Off” position the instrument panel lighting is at the
lowest light level and may not be suitable for night
driving.
Daytime Running Lights — If Equipped
The high beam headlights come on at a low intensity
level whenever the engine is running, and the transmis-
sion is not in the P (Park) position. The lights remain on
until the ignition switch is turned OFF or the parking
brake is engaged. The headlight switch must be used for
normal night time driving.
Lights-On Reminder
If the headlights or parking lights are on after the ignition
is turned OFF, a chime will sound when the driver’s door
is opened.
Fog Lights — If Equipped
The fog light switch is located in the multi-
function control lever. To activate the fog lights,
turn on the park/turn lights, low beam headlights,
or “Auto” headlights and pull out the end of the multi-
function control lever. A light in the instrument cluster
shows when the fog lights are on.
NOTE:Turning on the high beam headlights turns off
the fog lights.
A front fog light is a lighting device providing illumina-
tion forward of the vehicle under conditions of fog, rain,
snow, or dust. Principally, the front fog light supplements
the lower beam of a standard headlight system.
NOTE:Proper aim and adjustments of the front fog
lights should be made to prevent excessive glare for other
drivers.

ELECTRONIC SPEED CONTROL
When engaged, this device takes over accelerator opera-
tions at speeds greater than 25 mph (40 km/h) for 5.7L
engines, and 30 mph (48 km/h) for 3.7L/4.7L engines.
The controls are mounted on the steering wheel and
consist of ON·OFF, SET, RES·ACCEL, CANCEL, and
DECEL controls.
To Activate
Press the ON·OFF button to turn the system ON. To turn
the system OFF, press the ON·OFF button again. The
system should be turned OFF when not in use. The
CRUISE indicator light in the instrument cluster will
illuminate when the system is ON.
To Set at a Desired Speed
When the vehicle has reached the desired speed, press
and release the SET button. Release the accelerator and
the vehicle will operate at the selected speed.
To Deactivate
A soft tap on the brake pedal, normal braking, or pressing
the CANCEL button will deactivate the Speed Control
without erasing the memory. Pressing the ON·OFF to
turn the system OFF or turning off the ignition erases the
memory.

To Resume Speed
To resume a previously set speed, press and release the
RES·ACCEL button. Resume can be used at any speed
above 25 mph (40 km/h) for 5.7L engines, and 30 mph (48
km/h) for 3.7L/4.7L engines.
To Vary the Speed Setting
When the Speed Control is ON, speed can be increased
by pressing and holding the RES·ACCEL button. When
the button is released, a new set speed will be estab-
lished.
Tapping the RES·ACCEL button once will result in a 2
mph (3 km/h) (3.7L/4.7L Models) or a 1 mph (2 km/h)
(5.7L Models) speed increase. Each time the button is
tapped, speed increases, so tapping the button three
times will increase speed by 6 mph (10 km/h) (3.7L/4.7L
Models) or 3 mph (5 km/h) (5.7L Models), etc.To decrease speed while Speed Control is ON and SET,
press and hold the DECEL button. Release the button
when the desired speed is reached, and the new speed
will be set.
To Accelerate for Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
NOTE:When driving uphill, at elevations above 2,000
feet (610 meters), or when the vehicle is heavily loaded
(especially when towing) the vehicle may slow below the
SET speed. If the vehicle speed drops below 25 mph (40
km/h) for 5.7L models, or 30 mph (48 km/h) for 3.7L/
4.7L models, the Speed Control will automatically disen-
gage. If this happens, you can push down on the accel-
erator pedal to maintain the desired speed.
Vehicles may exhibit several 4-3 downshifts under the
above conditions. To reduce the frequency of the down-
shifts and to improve vehicle performance, it is advisable

TCS (Traction Control System)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system functions similar to
a limited slip differential and controls the wheel spin
across a driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will apply the
brake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
This feature remains active even if TCS and ESP are in
either the “Partial Off” or “Full Off” modes. Refer to “ESP
(Electronic Stability Program)” in this section.
BAS (Brake Assist System)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.

WARNING!
BAS (Brake Assist System) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents. The capabilities of a BAS-
equipped vehicle must never be exploited in a reck-
less or dangerous manner which could jeopardize
the user’s safety or the safety of others.
ERM (Electronic Roll Mitigation)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicles speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers.
ERM can only reduce the chance of wheel lift occurring
during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors such as road
conditions, leaving the roadway or striking objects or
other vehicles.
