Windshield Wipers
Clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, gently
loosen or thaw them. Damaged wiper blades may not
clear the windshield well, making it harder to see
and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-62.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools down.

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. DRL
can be helpful in many different driving conditions, but
they can be especially helpful in the short periods after
dawn and before sunset. DRL lamps are required to
function at all times on all vehicles rst sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered.
The DRL system will make the low-beam headlamps
come on at reduced brightness when the following
conditions are met:
The ignition is on.
The exterior lamps control is off.
The parking brake is released.
While the DRL are on, only the vehicle’s low-beam
headlamps will be on at reduced brightness. The turn
signal, taillamps, sidemarker, and other lamps will not be
on. The instrument panel will not be lit up either.

oor outlets with some air directed toward the side
window outlets and a little air directed to the windshield.
In this mode, the system will automatically use outside
air. The air conditioning compressor will be engaged
unless the outside temperature is 40°F (4°C) or below.

Passenger Compartment Air Filter
The passenger compartment air lter is located in
the engine compartment below the air inlet grille, near
the passenger’s side windshield wiper arm. See
Engine Compartment Overview on page 5-12.
The lter traps most of the pollen from the air entering
the air conditioning module. The lter needs to be
changed periodically to keep the air conditioning working
at its best. For information on how often to change
the passenger compartment air lter, seeScheduled

system warning light is also on, your vehicle does not
have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
