Coolant temperature
Modern engines are highly
susceptible to damage
from overheating—damage
that may not be immediately apparent.
Ask your AARS mechanic for a cooling
system pressure test, as well as an
operational test of the cooling fans.
Attention assist
Some vehicles recognize
signs of driver drowsiness
or inattention and
signal concern with a warning light.
Mercedes, for example, responds to
lapses in attention by displaying the
image of a coffee cup. If you’re feeling
tired, pull over at the nearest rest stop
or ask a passenger to take the wheel.

Dashboard Decoder
a guide to deciphering your vehicle’s warning lights
Today’s high-Tech dashes can display
up to 60 icons, like a puzzling set of
modern-day hieroglyphics. When
a dashboard warning light pops
up, it can unsettle even the most
seasoned driver. CAA Manitoba’s Dan
Messner—a manager in Automotive
Services with four decades of industry
experience—illuminates the subject.
Brakes
Depending on the vehicle,
this light may indicate
that the parking brake is
on, brake fluid level is low or there’s
a problem in the brake hydraulic
system. In most cases, a thorough
brake inspection is advisable.
Tire pressure monitor
It typically signals low air
pressure in one or more of
your tires. Check/adjust the
pressures, and inspect tires for punc-
tures, treadwear, sidewall bulges and
other signs of damage that may require
tire repair or replacement. When filling
tires, it’s important to be gentle with the
valve stems, as they can break easily.
Charging system
Usually indicates a bad
alternator or an electrical
wiring problem, some-
times accompanied by a defective
battery. Your nearest CAA Approved
Auto Repair Service (AARS) facility
can perform a thorough charging,
starting and battery test to isolate
the problem.
Oil pressure
This light usually means
bad news. An engine that
has run for almost any
amount of time with the oil pressure
warning light on has likely suffered
significant internal damage and
possibly complete destruction. If
this light comes on, shut your vehicle
off immediately and call CAA for a
tow to a repair shop.
Check engine
This light could mean a
number of things, from a
loose gas cap (a common
issue) or something more major that
requires an urgent fix. It could also
mean nothing at all (an unanticipated
driving condition, like ascending a
steep hill, could trigger the light). To
be safe, it’s best to get a proper diag-
nosis from a mechanic.
Traction control
Illuminates when the
vehicle’s electronic stability
system is in use. Typically
indicates slippery conditions. Proceed
with caution.
Air bags
This light may come on
when you first start your
car and disappear after
a second or two—that’s a good sign.
It means your bags are packed and
fully functioning. If, however, the
light comes on and stays on, it
means the air bag may not deploy
in a collision. Get it checked out as
soon as possible to ensure these
potential lifesavers are always at
the ready.
