Turn the end of the windshield wiper
lever to operate the rear window
wiper/washer.
OFF :Turns the system off.
INT : Intermittent wipes.
ON : Slow wipes.
1:Push the windshield wiper
lever forward to spray washer fluid
on the rear window. The lever
automatically returns to its original
position when released.
{Warning
In freezing weather, do not use
the washer until the windshield is
warmed. Otherwise the washer
fluid can form ice on the
windshield, blocking your vision.
Rear Wiper Arm Assembly
Protection
When using an automatic car wash,
move the rear wiper control to OFF
to disable the rear wiper. In some
vehicles, if the transmission is in
N (Neutral) and the vehicle speed is
very slow, the rear wiper will
automatically park.
The wiper operations return to
normal when the transmission is no
longer in N (Neutral) or the vehicle
speed has increased.
Reverse Gear Wipes
If the rear wiper control is off, the
rear wiper will automatically operate
continuously when the transmission
is in R (Reverse), and the front
windshield wiper is performing low or high speed wipes. If the rear
wiper control is off, the transmission
is in R (Reverse), and the front
windshield wiper is performing
interval wipes, then the rear wiper
automatically performs interval
wipes.
This feature can be turned on or off.
See
Vehicle Personalization 0142.
The windshield washer reservoir is
used for the windshield and rear
window. Check the fluid level if
either washer is not working. See
Washer Fluid 0282.
Compass
The vehicle may have a compass
display on the Driver Information
Center (DIC). The compass receives
its heading and other information
from the Global Positioning
System (GPS) antenna, StabiliTrak,
and vehicle speed information.
The compass system is designed to
operate for a certain number of
miles or degrees of turn before
needing a signal from the GPS
satellites. When the compass

or in pounds per square inch (psi).
Oil pressure can vary with engine
speed, outside temperature, and oil
viscosity. On some models, the oil
pump will vary engine oil pressure
according to engine needs. Oil
pressure may change quickly as the
engine speed or load varies. This is
normal. If the oil pressure warning
light or Driver Information Center
(DIC) message indicates oil
pressure outside the normal
operating range, check the vehicle's
oil as soon as possible.
Vehicle Messages

indicate the status of the vehicle or
some action that may be needed to
correct a condition. Multiple
messages may appear one after
another.
The messages that do not require
immediate action can be
acknowledged and cleared by
pressing
V. The messages that
require immediate action cannot be
cleared until that action is
performed.
All messages should be taken
seriously; clearing the message
does not correct the problem.

172 Driving and Operating
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.
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. Doing so could make the
pedal harder to push down. If the
engine stops, there will be some
power brake assist but it will be
used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the
brake pedal will be harder to push.
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. .
Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.
. Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. The Antilock Brake System
(ABS) allows steering while
braking.

Caution (Continued)
fuel system and engine, and
damages would not be covered
by the vehicle warranty.
Caution
Do not use blends containing
more than 20% biodiesel. Any
engine, fuel system, or exhaust
after-treatment system damage
would not be covered by the
vehicle warranty.
Biodiesel fuel quality degrades with
time and exposure to high
temperature quicker than Ultra Low
Sulfur Diesel fuel. More frequent
refueling provides the best
opportunity to have a supply of fresh
fuel. Storage at hot ambient
temperatures will accelerate
biodiesel degradation.
Owners who use very little fuel,
or who have vehicles stored for
extended periods of time, should avoid the use of biodiesel blended
fuels above 5% by volume. When
vehicles are stored for longer than
one month, they should be run out
of biodiesel to below one-quarter
tank, refueled with Ultra Low Sulfur
Diesel fuel, and driven at least
32 km (20 mi) before storage.
At temperatures below 0 °C (32 °F),
it is recommended to switch to Ultra
Low Sulfur Diesel fuel with no
biodiesel content, or to blends with
biodiesel containing less than 5% by
volume. At these extreme cold
temperatures, biodiesel blends
higher than 5% by volume may
cause fuel filter plugging and
system gelling, which can lead to
vehicle operability problems.
Fuels improperly blended for cold
temperature operation may result in
restricted fuel filters and degraded
vehicle performance. GM diesel
vehicles are equipped with a fuel
heating system to provide an extra
level of protection against filter
plugging from gelling or waxing of
conventional diesel fuel and
biodiesel blends. If the operating
temperature is far below the
temperature at which gelling or
waxing of the fuel occurs, the
system cannot prevent all cases of
filter plugging.
If the vehicle experiences a fuel
filter restriction, the on-board
monitoring system will alert the
driver that the fuel filter requires
service. The fuel filter, however, will
not prevent all damage caused by
poor quality biodiesel.
Cold Weather Operation
(Diesel)
In cold weather, the fuel filter may
become clogged by wax naturally
present in the fuel. To unclog it,
move the vehicle to a warm garage
area and allow the filter to warm up.
The fuel filter may need to be
replaced. See
Fuel Filter
Replacement (Diesel) 0246.
At temperatures below 0 °C (32 °F),
it is recommended to avoid using
biodiesel blends above 5% blend.
This blend may cause fuel filter
plugging, system gelling, and

installed. Add or remove fluid, as
necessary, only when work is done
on the brake hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid 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 0129.
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 0353. What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See
Recommended
Fluids and Lubricants 0361.{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.
Refer to the replacement number
shown on the original battery label
when a new battery is needed. See
Engine Compartment Overview
0264 for battery location.
The vehicle has an Absorbing Glass
Mat (AGM) 12-volt battery.
Installation of a standard 12-volt
battery will result in reduced 12-volt
battery life. When using a 12-volt
battery charger on the 12-volt AGM
battery, some chargers have an
AGM battery setting on the charger.
If available, use the AGM setting on
the charger, to limit charge voltage
to 14.8 volts. Follow the charger
manufacturer's instructions.
