Exterior Lighting
Exterior Lamp Controls
The exterior lamp control is on the
instrument panel to the left of the steering
wheel.
There are four positions:
O: Briefly turn the control to this position
to turn the automatic headlamps and
Daytime Running Lamps (DRL) off or
back on.
For vehicles first sold in Canada, the off
position only works for vehicles that are
shifted into the P (Park) position.
AUTO : Automatically turns the exterior
lamps on and off, depending on outside
lighting.
;: Turns on the parking lamps including
all lamps, except the headlamps.
2: Turns on the headlamps together with
the parking lamps and instrument panel
lights.
If the headlamps are turned on while the
vehicle is on, the headlamps turn off
automatically 10 minutes after the ignition
is turned off. If the headlamps are turned on
while the vehicle is off, the headlamps will
continue to stay on. To prevent the battery
from being drained, turn the control to the
Oposition.
A warning chime sounds if the driver door is
opened while the ignition switch is off and
the headlamps are on.
To change the headlamps from low beam to
high beam, pull the turn signal lever all the
way toward you. Then release it.
Exterior Lamps Off Reminder
If a door is open, a reminder chime sounds
when the headlamps or parking lamps are
manually turned on and the key is out of
the ignition. To turn off the chime, turn the
headlamp switch to
Oor AUTO and then
back on, or close and re-open the door. In

92 Lighting
The vehicle has a light sensor on the top of
the instrument panel. Do not cover the
sensor; otherwise the system will come on
whenever the ignition is on.
The system may also turn on the headlamps
when driving through a parking garage or
tunnel.
There is a delay in the transition between
the daytime and nighttime operation of the
Daytime Running Lamps (DRL) and the
automatic headlamp system so that driving
under bridges or bright overhead street
lights does not affect the system. The DRL
and automatic headlamp system are only
affected when the light sensor sees a
change in lighting lasting longer than the
delay.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. Once the vehicle leaves the
garage, it takes approximately 30 seconds
for the automatic headlamp system to
change to DRL if it is light outside. 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. SeeInstrument Panel
Illumination Control 093. To idle the vehicle with the automatic
headlamp system off, turn the control off.
The headlamps will also stay on after
exiting the vehicle. This feature may be
programmable. See
Vehicle Personalization
0 86.
If the feature is not programmable, exit
lighting is automatic. When it is dark
enough outside, the exterior lamps remain
on for 30 seconds after the ignition is
turned off.
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 come on. The transition time
for the lamps coming on varies based on
wiper speed. When the wipers are not
operating, these lamps turn off. Move the
exterior lamp control to
Por;to
disable this feature.
Hazard Warning Flashers
|: Press this button 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.
When the hazard warning flashers are on,
the vehicle's turn signals will not work.

126 Driving and Operating
Driving Information
Driving for Better Fuel Economy
Driving habits can affect fuel mileage. Here
are some driving tips to get the best fuel
economy possible:
.Set the climate controls to the desired
temperature after the engine is started,
or turn them off when not required.
.Avoid fast starts and accelerate smoothly.
.Brake gradually and avoid abrupt stops.
.Avoid idling the engine for long periods
of time.
.When road and weather conditions are
appropriate, use cruise control.
.Always follow posted speed limits or
drive more slowly when conditions
require.
.Keep vehicle tires properly inflated.
.Combine several trips into a single trip.
.Replace the vehicle's tires with the same
TPC Spec number molded into the tire's
sidewall near the size.
.Follow recommended scheduled
maintenance.
Distracted Driving
Distraction comes in many forms and can
take your focus from the task of driving.
Exercise good judgment and do not let other
activities divert your attention away from
the road. Many local governments have
enacted laws regarding driver distraction.
Become familiar with the local laws in
your area.
To avoid distracted driving, keep your eyes
on the road, keep your hands on the
steering wheel, and focus your attention on
driving.
.Do not use a phone in demanding driving
situations. Use a hands-free method to
place or receive necessary phone calls.
.Watch the road. Do not read, take notes,
or look up information on phones or
other electronic devices.
.Designate a front seat passenger to
handle potential distractions.
.Become familiar with vehicle features
before driving, such as programming
favorite radio stations and adjusting
climate control and seat settings. Program
all trip information into any navigation
device prior to driving.
.Wait until the vehicle is parked to
retrieve items that have fallen to the
floor.
.Stop or park the vehicle to tend to
children.
.Keep pets in an appropriate carrier or
restraint.
.Avoid stressful conversations while
driving, whether with a passenger or on a
cell phone.
{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 section 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 Belts 028.

14583525) - 2021 - CRC - 12/9/20
Driving and Operating 127
.Assume that other road users
(pedestrians, bicyclists, and other drivers)
are going to be careless and make
mistakes. Anticipate what they may do
and be ready.
.Allow enough following distance between
you and the driver in front of you.
.Focus on the task of driving.
Impaired Driving
Death and injury associated with impaired
driving is a global tragedy.
{Warning
Drinking alcohol or taking drugs and then
driving is very dangerous. Your reflexes,
perceptions, attentiveness, and judgment
can be affected by even a small amount
of alcohol or drugs. You can have a
serious—or even fatal —collision if you
drive after drinking or taking drugs.
Do not drive while under the influence of
alcohol or drugs, or ride with a driver
who has been drinking or is impaired by
drugs. Find alternate transportation
home; or if you are with a group,
designate a driver who will remain sober.
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. Once the power assist is used up, it
can take longer to stop and the brake pedal
will be harder to push.
Steering
Caution
To avoid damage to the steering system,
do not drive over curbs, parking barriers,
or similar objects at speeds greater than
3 km/h (1 mph). Use care when driving
over other objects such as lane dividers
and speed bumps. Damage caused by
misuse of the vehicle is not covered by
the vehicle warranty.
