Engine Coolant
Temperature Gauge
Metric
English
This gauge shows the engine
coolant temperature. Under normal
driving conditions the gauge will
read 100°C (210°F) or less. If the
gauge pointer is near 125°C
(260°F), the engine is too hot.
It means that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible.
See Engine Overheating on
page 10-16 for more information.
Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts.
When the engine is running, this
gauge shows the condition of the
charging system. The vehicle's
charging system regulates voltage
based on the state of charge of the
battery. The voltmeter may fluctuate.
This is normal. Readings between
the low and high warning zones
indicate the normal operating range.

0(Defrost):Press to turn the
defrost on or off. This mode quickly
clears the windshield of fog or frost.
Air is directed to the windshield,
side window, and floor vents. In this
mode, outside air is pulled inside
the vehicle. The air conditioning
system runs automatically in this
setting, unless the outside

Air Conditioning
A/C (Air Conditioning): Press to
turn the air conditioning on and off.
An indicator light comes on when
A/C is on.
The A/C does not work when the
outside temperature is below 4°C
(40°F). If A/C is pressed the
indicator flashes three times and turns off to show that the A/C mode
is not available. If the A/C is on and
the outside temperature drops
below a temperature which is too
cool for air conditioning to be
effective, the A/C indicator turns off
to show that the A/C mode has
been canceled.
On hot days, open the windows
briefly to let hot inside air escape.
This helps reduce the time it takes
for the interior of the vehicle to
cool down.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.@(Recirculation):
Press to
alternate between recirculating air
inside the vehicle or pulling in
outside air. An indicator light comes
on when recirculation mode is
active. With each ignition cycle, the
recirculation mode is reset to
automatic. When the engine is turned on, outside air or
recirculation is automatically
selected for better performance.
When recirculation is activated, the
air conditioning compressor comes
on and helps to quickly cool the air
inside the vehicle. This mode also
helps to reduce the outside air and
odors that may enter the vehicle.
The recirculation mode cannot be
used with floor, defog, or defrosting
modes. If recirculation is selected in
these modes, the indicator flashes
three times and turns off. While in
recirculation mode the windows can
fog when the weather is cold and
damp. To clear the fog, select either
the defog or defrost mode and
increase the fan speed.

.Be alert on top of hills;
something could be in your lane
(stalled car, accident).
.Pay attention to special road
signs (falling rocks area, winding
roads, long grades, passing or
no-passing zones) and take
appropriate action.
Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip. Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.
Traction Control should be turned
on. See
Traction Control/Electronic
Stability Control on page 9-28.
The Antilock Brake System (ABS)
improves vehicle stability during
hard stops on slippery roads, but
apply the brakes sooner than when
on dry pavement. See Antilock
Brake System (ABS) on page 9-26.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
