Making TurnsCaution
Turn more slowly and make wider
arcs when towing a trailer to
prevent damage to your vehicle.
Making very sharp turns could
cause the trailer to contact the
vehicle.
Make wider turns than normal when
towing, so trailer will not go over soft
shoulders, over curbs, or strike road
signs, trees, or other objects.
Always signal turns well in advance.
Do not steer or brake suddenly.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downhill grade. If the
transmission is not shifted down, the
brakes may overheat and result in
reduced braking efficiency. The vehicle can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts too
often under heavy loads and/or hilly
conditions.
When towing at higher altitudes,
engine coolant will boil at a lower
temperature than at lower altitudes.
If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle could show signs similar to
engine overheating. To avoid this,
let the engine run, preferably on
level ground, with the transmission
in P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating
0237.Parking on Hills
{Warning
To prevent serious injury or death,
always park your vehicle and
trailer on a level surface when
possible. When parking your vehicle and your
trailer on a hill:
1. Press the brake pedal, but do not shift into P (Park) yet. Turn
the wheels into the curb if
facing downhill or into traffic if
facing uphill.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, gradually release the
brake pedal to allow the chocks
to absorb the load of the trailer.
4. Reapply the brake pedal. Then apply the parking brake and
shift into P (Park).
5. Release the brake pedal.
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
.Start the engine.
. Shift into a gear.
. Release the parking brake.
2. Let up on the brake pedal.

Vehicle Care 241
{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 0123.
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 0301.
What to Add
Use only GM approved DOT 3
brake fluid from a clean, sealed
container. See Recommended
Fluids and Lubricants 0309.
{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 standard 12-volt
battery under the hood. See Engine
Compartment Overview 0225.
Refer to the replacement number shown on the original battery label
when a new 12-volt battery is
needed.
Stop/Start System
If equipped with the 2.5L L4 engine,
the vehicle has a Stop/Start system
to shut off the engine to help
conserve fuel. See
Starting the
Engine 0174.
Vehicles with Stop/Start have an
Absorbed Glass Mat (AGM) 12-volt
underhood battery. Installation of a
standard 12-volt battery will result in
reduced 12-volt battery life.
There is also an auxiliary AGM
battery behind the access panel in
the left rear of the trunk. This battery
is for managing the Stop/Start
auxiliary loads and is not to be used
for any other purpose. See your
dealer if the auxiliary battery needs
service.
When using a 12-volt battery
charger on the 12-volt AGM battery,
some chargers have an AGM
battery setting on the charger.

1. Turn the wrenchcounterclockwise to remove the
fastener.
2. Replace the fastener with the one provided in the foam.
3. Turn the wrench clockwise to tighten the fastener.
4. Replace the foam, jack and tools, and the tire.
5. Turn the retainer nut clockwise to secure the tire.
6. Place the floor cover on the wheel.
To store the compact spare tire, use
the shorter mounting bolt. The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the
vehicle. The compact spare tire is
designed for temporary use only. The vehicle will perform differently
with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of
the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area.
When using a compact spare tire,
the AWD (if equipped), ABS, and
Traction Control systems may
engage until the spare tire is
recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel,
and other parts of the vehicle.

Locks
Locks are lubricated at the factory.
Use a de-icing agent only when
absolutely necessary, and have the
locks greased after using. See
Recommended Fluids and
Lubricants 0309.
Washing the Vehicle
To preserve the vehicle's finish,
wash it often and out of direct
sunlight.
Caution
