Roof Rack System
{Warning
If something is carried on top of
the vehicle that is longer or wider
than the roof rack—like paneling,
plywood, or a mattress —the
wind can catch it while the vehicle
is being driven. The item being
carried could be violently torn off,
and this could cause a collision
and damage the vehicle. Never
carry something longer or wider
than the roof rack on top of the
vehicle unless using a GM
certified accessory carrier.
If equipped, the roof rack can be
used to load items. For roof racks
that do not have crossrails included,
GM Certified crossrails can be
purchased as an accessory. See
your dealer for additional
information.
{Caution
Loading cargo on the roof rack
that weighs more than 100 kg
(220 lb) or hangs over the rear or
sides of the vehicle may damage
the vehicle. Load cargo so that it
rests evenly between the
crossrails, making sure to fasten
cargo securely.
To prevent damage or loss of cargo
when driving, check to make sure
crossrails and cargo are securely
fastened. Loading cargo on the roof
rack will make the vehicle’ s center
of gravity higher. Avoid high speeds,
sudden starts, sharp turns, sudden
braking, or abrupt maneuvers,
otherwise it may result in loss of
control. If driving for a long distance,
on rough roads, or at high speeds,
occasionally stop the vehicle to
make sure the cargo remains in its
place. Do not exceed the maximum vehicle
capacity when loading the vehicle.
For more information on vehicle
capacity and loading, see
Vehicle
Load Limits on page 9-14.
A Center High-Mounted Stoplamp
(CHMSL) is located above the rear
window glass. Make sure items
loaded on the roof of the vehicle do
not block or damage the CHMSL.

Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Warning lights come on when there
could be a problem with a vehicle
function. Some warning lights come
on briefly when the engine is started
to indicate they are working.Gauges can indicate when there
could be a problem with a vehicle
function. Often gauges and warning
lights work together to indicate a
problem with the vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gauges
shows there may be a problem,
check the section that explains what
to do. Follow this manual's advice.
Waiting to do repairs can be costly
and even dangerous.

Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper-resistant
odometer. If the vehicle needs a
new cluster installed, the new
odometer is set to the mileage of
the old odometer. If this is not
possible, it is set at zero and a label
is put on the driver door to show the

Engine Coolant
Temperature Gauge
Metric
English
This gauge measures the
temperature of the vehicle's engine
coolant.
While driving under normal
operating conditions, if the needle
moves into the red warning area,
the engine is too hot. Pull off the
road, stop the vehicle, and turn off
the engine as soon as possible.
Voltmeter Gauge
When the ignition is on, this gauge
indicates the battery voltage.
When the engine is running, this
gauge shows the condition of the
charging system. The gauge can
transition from a higher to lower or a
lower to higher reading. This is
normal. If the vehicle is operating
outside the normal operating range,
the charging system light comes on.

voltmeter gauge may also read
lower when in fuel economy mode.
This is normal.
Readings outside the normal
operating range can also occur
when a large number of electrical
accessories are operating in the
vehicle and the engine is left idling
for an extended period. This
condition is normal since the
charging system is not able to
provide full power at engine idle. As
engine speeds are increased, this
condition should correct itself as
higher engine speeds allow the
charging system to create maximum
power.
The vehicle can only be driven for a
short time with the readings outside
the normal operating range. If the
vehicle must be driven, turn off all
accessories, such as the radio and
air conditioner.Readings outside the normal
operating range indicate a possible
problem in the electrical system.
Have the vehicle serviced as soon
as possible.
