Daytime Running Lamps
(DRL)/Automatic
Headlamp System
Daytime Running Lamps (DRL) can
make it easier for others to see the
front of your vehicle during the day.
Fully functional daytime running
lamps are required on all vehicles
first sold in Canada.
The DRL system makes either the
low-beam headlamps come on at a
reduced brightness or the DRL
lights, for vehicles with High
Intensity Discharge (HID)
headlamps when the following
conditions are met:
.The ignition is in the ON/RUN
position.
.The exterior lamps control is
in AUTO.
.The engine is running.When the DRL are on, the regular
headlamps, taillamps, sidemarker,
and other lamps will not be on. The
instrument panel and cluster will
also not be lit.
For vehicles with HID headlamps,
if the DRL are on and the left or
right turn signal lamp is turned on,
the left or right DRL will go off.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings. The
other lamps that come on with the
headlamps will also come on.
When it is bright enough outside,
the headlamps will go off and the
DRL will come on.
The regular headlamp system
should be turned on when needed.
Do not cover the light sensor on top
of the instrument panel because it
works with the DRL.
Hazard Warning Flashers

Hazard Warning Flasher:
Press this button located on the
instrument panel below the audio
system, to make the front and rear
turn signal lamps flash on and off.
This warns others that you are
having trouble. Press again to turn
the flashers off.
The turn signals do not work while
the hazard warning flashers are on.

Driving and Operating 9-3
Medical research shows that alcohol
in a person's system can make
crash injuries worse, especially
injuries to the brain, spinal cord,
or heart. This means that when
anyone who has been
drinking—driver or passenger —is
in a crash, that person's chance of
being killed or permanently disabled
is higher than if the person had not
been drinking.
Control of a Vehicle
The following three systems help to
control the vehicle while
driving —brakes, steering, and
accelerator. At times, as when
driving on snow or ice, it is easy to
ask more of those control systems
than the tires and road can provide.
Meaning, you can lose control of the
vehicle. See StabiliTrak System
on
page 9‑28.
Adding non-dealer/non-retailer
accessories can affect vehicle
performance. See Accessories and
Modifications on page 10‑3.
Braking
See Brake System Warning Lighton page 5‑19.
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average reaction time is about
three-fourths of a second. But that is
only an average. It might be less
with one driver and as long as two
or three seconds or more with
another. Age, physical condition,
alertness, coordination, and
eyesight all play a part. So do
alcohol, drugs, and frustration. But
even in three-fourths of a second, a
vehicle moving at 100 km/h
(60 mph) travels 20 m (66 ft). That
could be a lot of distance in an
emergency, so keeping enough
space between the vehicle and
others is important.
And, of course, actual stopping
distances vary greatly with the
surface of the road, whether it is pavement or gravel; the condition of
the road, whether it is wet, dry,
or icy; tire tread; the condition of the
brakes; the weight of the vehicle;
and the amount of brake force
applied.
Avoid needless heavy braking.
Some people drive in
spurts
—heavy acceleration
followed by heavy braking —rather
than keeping pace with traffic. This
is a mistake. The brakes might not
have time to cool between hard
stops. The brakes will wear out
much faster with a lot of heavy
braking. Keeping pace with the
traffic and allowing realistic following
distances eliminates a lot of
unnecessary braking. That means
better braking and longer brake life.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. If the brakes are pumped,
the pedal could get harder to push
down. If the engine stops, there will
still be some power brake assist but
it will be used when the brake is

9-6 Driving and Operating
tires to slip and lose cornering force.
And in the acceleration skid, too
much throttle causes the driving
wheels to spin.
If the vehicle starts to slide, ease
your foot off the accelerator pedal
and quickly steer the way you want
the vehicle to go. If you start
steering quickly enough, the vehicle
may straighten out. Always be ready
for a second skid if it occurs.
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
slow down and adjust your driving to
these conditions. It is important to
slow down on slippery surfaces
because stopping distance is longer
and vehicle control more limited.
While driving on a surface with
reduced traction, try your best to
avoid sudden steering, acceleration,
or braking, including reducing
vehicle speed by shifting to a lowergear. Any sudden changes could
cause the tires to slide. You might
not realize the surface is slippery
until the vehicle is skidding. Learn to
recognize warning clues
—such as
enough water, ice, or packed snow
on the road to make a mirrored
surface —and slow down when you
have any doubt.
Remember: Any Antilock Brake
System (ABS) helps avoid only the
braking skid.
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep-standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause your
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
