To turn off the DRL, turn the exterior
lamp control to
Oor shift into
P (Park). The DRL will stay off until
the control is toggled again or the
transmission is shifted out of
P (Park).
For vehicles first sold in Canada,
the DRL can only be turned off
when the vehicle is parked.
Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps and parking
lamps come on automatically.
There is a light sensor on top of the
instrument panel. Do not cover the
sensor, otherwise the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps and parking lamps when
driving through a parking garage or
tunnel.
If the vehicle is started in a dark
garage, the automatic headlamp
system comes on immediately. If it
is light outside when the vehicle
leaves the garage, there is a slight
delay before the automatic
headlamp system changes to the
DRL. During that delay, the
instrument cluster may not be as
bright as usual. Make sure the
instrument panel brightness control
is in the full bright position. See
Instrument Panel Illumination
Control 0143.
When it is bright enough outside,
the headlamps and parking lamps
will turn off or may change to
Daytime Running Lamps (DRL). The automatic headlamp system
turns off when the exterior lamp
control is turned to
Oor the ignition
is off.
To turn automatic headlamp system
back on, turn the band to
Oagain,
then release it.
If the automatic headlamp system
has the headlamps turned on and
you turn the ignition off, the
headlamps will turn off. When the
driver door is opened the
headlamps and parking lamps will
illuminate for a period of time.
The length of the delayed
illumination period can be changed.
See “Exit Lighting” underVehicle
Personalization 0128.
The regular headlamp system
should be turned on when needed.
Lights On with Wipers
If the windshield wipers are
activated in daylight with the engine
on and the exterior lamp control is in
AUTO, the headlamps, parking
lamps, and other exterior lamps will
come on. The time it takes for the

Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter reduces dust, pollen, and other
airborne irritants from outside air
that is pulled into the vehicle.
Reductions in airflow, which may
occur more often in dusty areas,
indicate that the filter may need to
be replaced. See Maintenance
Schedule 0312.
Caution
Driving without a passenger
compartment air filter in place can
cause water and small particles,
like paper and leaves, to be
pulled into your climate control
system which may cause damage
to it. Make sure you always
replace the old filter with a
new one. The passenger compartment air
filter is on the passenger side of the
engine compartment near the
coolant surge tank. See
Engine
Compartment Overview 0225.
To check or replace the air filter:
1. Release the retainer clips from the passenger compartment air
filter cover. The PVC hoses
may need to be held out of the
way briefly to access the air
filter cover.
2. Remove the cover.

{Warning
Taking your eyes off the road too
long or too often could cause a
crash resulting in injury or death.
Focus your attention on driving.
Refer to the infotainment manual for
more information on using that
system and the navigation system,
if equipped, including pairing and
using a cell phone.
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
the seat belt. See Seat Belts066.
. Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready.
. Allow enough following distance
between you and the driver in
front of you. .
Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious —or even
fatal —collision if you drive after
drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and accelerating
are important factors in helping to
control a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is
about three-quarters of a second. In
that time, a vehicle moving at
100 km/h (60 mph) travels 20 m
(66 ft), which could be a lot of
distance in an emergency.
Helpful braking tips to keep in mind
include:
. Keep enough distance between
you and the vehicle in front
of you.
. Avoid needless heavy braking.
. Keep pace with traffic.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. Doing so could make the
pedal harder to push down. If the
engine stops, there will be some
power brake assist but it will be
used when the brake is applied.

162 Driving and Operating
vehicle for racing or other
competitive driving. SeeCompetitive
Driving Mode 0203.
A manual transmission is
recommended for extended track
usage at higher ambient
temperatures. Consult the Track
Preparation Guide for additional
information. See your dealer.
Be sure to follow all service
procedures before driving the
vehicle at track events or
competitively.
Prior to each track event and again
before re-entering the public road
system, tighten the wheel nuts with
a torque wrench to the proper
torque specification. See Capacities
and Specifications 0326.Engine Sound Management
Setting
Caution
Do not place the vehicle in
Engine Sound Management –
Stealth mode. Damage could
result to exhaust valve actuators.
Engine Oil
Caution
If the vehicle is used for track
events and competitive driving,
the engine may use more oil than
it would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil0232.
The engine is factory filled with
0W-40 dexos2 oil. For LT1 and LT4
engines only, 0W-40 dexos2 engine
oil is approved for both track and
street use. 15W-50 full synthetic engine oil may also be used for
track use, but after track use must
be changed back to 0W-40 dexos2
for street use. If 0W-40 dexos2 oil is
not available, 5W-30 dexos1 full
synthetic engine oil may be used for
street use. If 5W-30 dexos1 is used,
it must be changed to 0W-40
dexos2 or 15W-50 full synthetic
engine oil for track use.
For the LT5 engine, SAE 15W-50
full synthetic engine oil must be
used for track use, but after track
use must be changed back to
0W-40 dexos2 for street use.
Z51 Performance Package, Grand
Sport, Z06, and ZR1: Check the oil
level often during track events and
competitive driving and keep the
level at or near 0.5 L (0.5 qt) above
the upper mark that shows the
proper operating range on the
engine oil dipstick. After the
competitive driving, remove excess
oil so that the level on the dipstick is
not above the upper mark that
shows the proper operating range.
