Driving and Operating 195
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious—or even
fatal —collision if you drive after
drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
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.
Steering
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required. If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
If the steering assist is used for an
extended period of time while the
vehicle is not moving, power assist
may be reduced.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See your dealer if there is a
problem.
Curve Tips
.
Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.

198 Driving and Operating
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain.
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
electric drive unit.
. Keep the vehicle in gear when
going down steep or long hills.
{Warning
Coasting downhill in N (Neutral)
or with the vehicle turned off is
dangerous. The brakes will have
to do all the work of slowing down
the vehicle and could become too
hot. Hot brakes may not be able
to slow the vehicle enough to
maintain speed and control. You
could crash. Always have the
vehicle running and in gear when
going downhill. This will allow the
electric drive unit to assist in
slowing and maintaining speed.
. Drive at speeds to keep the
vehicle in its own lane. Do not
swing wide or cross the
center line.
. Be alert on top of hills.
Something could be in your lane
(e.g., stalled car, accident). .
Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Recommend using D (Drive) in
slippery conditions.
. Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on the Traction Control
System (TCS).

It is not necessary to regularly
check coolant unless a leak is
suspected or an unusual noise is
heard. A coolant loss could indicate
a problem. Have it inspected and
repaired by your dealer.
The following explains the cooling
systems and how to check coolant
levels.
.
High Voltage Battery
. Single Power Inverter Module
(SPIM), Accessory Power
Module (APM), and Charger
Module
. Cabin Heating
High Voltage Battery
During vehicle operation and also
during charging, the high voltage
battery cells in the vehicle are kept
within a normal operating
temperature range. If the
temperature rises above this
temperature, the battery cooling
system turns on the air conditioning
compressor and cools the coolant until the correct temperature is
reached. If the temperature falls
below this temperature, a high
voltage heater, located outside the
battery on a cradle, heats the
coolant until the correct temperature
is reached.
Single Power Inverter Module
(SPIM), Accessory Power
Module (APM), and Charger
Module
The SPIM, APM, and charger
module are cooled using a separate
coolant loop. These modules are
kept below a maximum temperature.
If the temperature rises above this
temperature, the electric cooling fan
will turn on to cool the coolant.
Cabin Heating
Cabin heating is maintained by
coolant heated by the Coolant
Heater Control Module (CHCM),
separate from the power electronics
and battery coolant loops. This
module heats the coolant based on
temperature inputs from the cabin
climate control systems.

Caution
.Do not use washer fluid that
contains any type of water
repellent coating. This can
cause the wiper blades to
chatter or skip.
. Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
. Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of the
washer system.
. When using concentrated
washer fluid, follow the
manufacturer instructions for
adding water.
. Fill the washer fluid tank
only three-quarters full when
it is very cold. This allows
(Continued)
Caution (Continued)
for fluid expansion if
freezing occurs, which could
damage the tank if it is
completely full.
Brakes
Disc brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or can
be heard all the time when the
vehicle is moving, except when
applying the brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications. See Capacities and
Specifications 0331.
Brake pads should be replaced as
complete sets.
Brake Pedal Travel
See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service may be required.

Vehicle Care 263
Replacing Brake System Parts
Always replace brake system parts
with new, approved replacement
parts. If this is not done, the brakes
may not work properly. The braking
performance expected can change
in many other ways if the wrong
replacement brake parts are
installed or if parts are improperly
installed.
Brake Fluid
The brake master cylinder reservoir
is filled with GM approved DOT 3
brake fluid as indicated on the
reservoir cap. SeeUnderhood
Compartment Overview 0259 for
the location of the reservoir. Checking Brake Fluid
With the vehicle in P (Park) on a
level surface, the brake fluid level
should be between the minimum
and maximum marks on the brake
fluid reservoir.
There are only two reasons why the
brake fluid level in the reservoir may
go down:
.
Normal brake lining wear. When
new linings are installed, the
fluid level goes back up.
. A fluid leak in the brake
hydraulic system. Have the
brake hydraulic system fixed.
With a leak, the brakes will not
work well.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it.
Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See
Brake System Warning
Light 0126.
Brake fluid absorbs water over time
which degrades the effectiveness of
the brake fluid. Replace brake fluid
at the specified intervals to prevent
increased stopping distance. See
Maintenance Schedule 0322.
What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0327.
{Warning
The wrong or contaminated brake
fluid could result in damage to the
brake system. This could result in
the loss of braking leading to a
possible injury. Always use the
proper GM approved brake fluid.

Caution
If brake fluid is spilled on the
vehicle's painted surfaces, the
paint finish can be damaged.
Immediately wash off any painted
surface.
Battery - North America
The original equipment battery is
maintenance free. Do not remove
the cap and do not add fluid.
This vehicle has a high voltage
battery and a standard 12-volt
battery.
{Warning
Damage to the high voltage
battery or high voltage system
can create a risk of electric shock,
overheating, or fire.
If the vehicle is damaged from a
moderate to severe crash, flood,
fire, or other event, the vehicle(Continued)
Warning (Continued)
should be inspected as soon as
possible. Until the vehicle has
been inspected, store it outside at
least 15 m (50 ft) from any
structure or anything that can
burn. Ventilate the vehicle by
opening a window or a door.
Contact Customer Assistance as
soon as possible to determine
whether an inspection is needed.
SeeCustomer Assistance Offices
0 334.
If the vehicle is in a crash, the
sensing system may shut down the
high voltage system. When this
occurs, the high voltage battery is
disconnected and the vehicle will
not start. The SERVICE VEHICLE
SOON message in the Driver
Information Center (DIC) will be
displayed. Before the vehicle can be
operated again, it must be serviced
at your dealer. See
“If a Crash Occurs” under
Collision Damage Repair 0339 for
additional information. If an airbag
has inflated, see What Will You See
after an Airbag Inflates? 075.
Only a trained service technician
with the proper knowledge and tools
should inspect, test, or replace the
high voltage battery. See your
dealer if either the 12-volt or high
voltage battery needs service. The
dealer has information on how to
recycle the high voltage battery.
There is also information available
at http://www.recyclemybattery.com.
Keep the vehicle plugged in, even
when fully charged, to keep the high
voltage battery temperature ready
for the next drive. This is important
when outside temperatures are
extremely hot or cold.
Propulsion power may be reduced
in extremely cold temperatures, or if
the high voltage battery is too cold.
