2010 CHEVROLET IMPALA light

This light will flash when
the TCS is limiting
wheel spin.
The system may be heard or felt while it is working, but
this is normal.
If cruise control is being used when TCS begins to limit
wheel spin, the cruise control will automatically
disengage. Cruise control may be reengaged when road
conditions allow. SeeCruise Control on page 4-6.
The TCS operates in all transmission shift lever
positions. But the system can upshift the transmission
only as high as the shift lever position chosen, so
use the lower gears only when necessary. See
Automatic Transmission Operation on page 3-24.When the system is on,
this warning light comes
on and stays on if there is
a problem.
A SERVICE TRACTION CONTROL message also
appears on the DIC. When this warning light is on, the
system will not limit wheel spin. Adjust your driving
accordingly. SeeDIC Warnings and Messages
on page 4-44for more information.
To limit wheel spin, especially in slippery road
conditions, TCS should always be left on. But the
system can be turned off if needed. Turn the system off
if the vehicle gets stuck in sand, mud or snow and
rocking the vehicle is required. SeeRocking Your
Vehicle to Get It Out on page 5-20andIf Your Vehicle
is Stuck in Sand, Mud, Ice, or Snow on page 5-19
for more information.

To turn the system on or
off, press the Traction
Control button located on
the instrument panel.
When the system is turned off, the traction control
warning light comes on and TRACTION CONTROL OFF
appears on the DIC. If the traction control system is
limiting wheel spin when the button is pressed to turn the
system off, the warning light comes on and the system
will turn off right away.
Press the Traction Control button again to turn the
system back on. The Traction Control warning light
should go off.
Adding non-dealer/non-retailer accessories can affect
the vehicle’s performance. SeeAccessories and
Modifications on page 6-3for more information.
SteeringPower SteeringIf power steering assist is lost because the engine stops
or the system is not functioning, the vehicle can be
steered but it will take more effort.Steering TipsIt is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and vehicle speed. While in a curve, speed is
the one factor that can be controlled.
If there is a need to reduce speed, do it before entering
the curve, while the front wheels are straight.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait
to accelerate until out of the curve, and then accelerate
gently into the straightaway.

Off-Road RecoveryThe vehicle’s right wheels can drop off the edge of a
road onto the shoulder while driving.
If the level of the shoulder is only slightly below the
pavement, recovery should be fairly easy. Ease off the
accelerator and then, if there is nothing in the way, steer
so that the vehicle straddles the edge of the pavement.
Turn the steering wheel 8 to 13 cm (3 to 5 inches), about
one-eighth turn, until the right front tire contacts the
pavement edge. Then turn the steering wheel to go
straight down the roadway.
PassingPassing another vehicle on a two-lane road can be
dangerous. To reduce the risk of danger while passing:•
Look down the road, to the sides, and to crossroads
for situations that might affect a successful pass.
If in doubt, wait.
•
Watch for traffic signs, pavement markings, and
lines that could indicate a turn or an intersection.
Never cross a solid or double-solid line on your side
of the lane.
•
Do not get too close to the vehicle you want to
pass. Doing so can reduce your visibility.
•
Wait your turn to pass a slow vehicle.
•
When you are being passed, ease to the right.
Loss of ControlLet us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough friction
where the tires meet the road to do what the driver has
asked.
In any emergency, do not give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.

Driving at NightNight driving is more dangerous than day driving because
some drivers are likely to be impaired — by alcohol or
drugs, with night vision problems, or by fatigue.
Night driving tips include:•
Drive defensively.
•
Do not drink and drive.
•
Reduce headlamp glare by adjusting the inside
rearview mirror.
•
Slow down and keep more space between you and
other vehicles because headlamps can only light up
so much road ahead.
•
Watch for animals.
•
When tired, pull off the road.
•
Do not wear sunglasses.
•
Avoid staring directly into approaching headlamps.
•
Keep the windshield and all glass on your vehicle
clean — inside and out.
•
Keep your eyes moving, especially during turns or
curves.
No one can see as well at night as in the daytime.
But, as we get older, these differences increase.
A 50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.

Driving in Rain and on Wet RoadsRain and wet roads can reduce vehicle traction
and affect your ability to stop and accelerate. Always
drive slower in these types of driving conditions
and avoid driving through large puddles and
deep-standing or flowing water.
{
WARNING:
Wet brakes can cause crashes. They might not
work as well in a quick stop and could cause
pulling to one side. You could lose control of the
vehicle.
After driving through a large puddle of water or a
car/vehicle wash, lightly apply the brake pedal until
the brakes work normally.
Flowing or rushing water creates strong forces.
Driving through flowing water could cause your
vehicle to be carried away. If this happens, you
and other vehicle occupants could drown. Do not
ignore police warnings and be very cautious about
trying to drive through flowing water.
HydroplaningHydroplaning is dangerous. Water can build up under
your vehicle’s tires so they actually ride on the
water. This can happen if the road is wet enough and
you are going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.Other Rainy Weather TipsBesides 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. SeeTires
on page 6-51.
•
Turn off cruise control.

Repeat this until help arrives but only when you feel
really uncomfortable from the cold. Moving about
to keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery charged to restart
the vehicle and to signal for help with the headlamps.
Do this as little as possible to save fuel.If Your Vehicle is Stuck in Sand,
Mud, Ice, or SnowSlowly and cautiously spin the wheels to free the
vehicle when stuck in sand, mud, ice, or snow. See
Rocking Your Vehicle to Get It Out on page 5-20.
If the vehicle has a traction system, it can often help to
free a stuck vehicle. Refer to the vehicle’s traction
system in the Index. If stuck too severely for the traction
system to free the vehicle, turn the traction system off
and use the rocking method.
{
WARNING:
If the vehicle’s tires spin at high speed, they can
explode, and you or others could be injured. The
vehicle can overheat, causing an engine
compartment fire or other damage. Spin the
wheels as little as possible and avoid going above
55 km/h (35 mph) as shown on the speedometer.
For information about using tire chains on the vehicle,
seeTire Chains on page 6-73.
5-19

Rocking Your Vehicle to Get It OutTurn the steering wheel left and right to clear the
area around the front wheels. Turn off any traction
system. Shift back and forth between R (Reverse) and a
forward gear, spinning the wheels as little as possible.
To prevent transmission wear, wait until the wheels stop
spinning before shifting gears. Release the accelerator
pedal while shifting, and press lightly on the accelerator
pedal when the transmission is in gear. Slowly
spinning the wheels in the forward and reverse
directions causes a rocking motion that could free the
vehicle. If that does not get the vehicle out after a
few tries, it might need to be towed out. If the vehicle
does need to be towed out, seeTowing Your Vehicle on
page 5-26.
Loading the VehicleIt is very important to know how much weight your
vehicle can carry. Two labels on your vehicle
show how much weight it may properly carry, the
Tire and Loading Information label and the
Vehicle Certification label.
{
WARNING:
Do not load the vehicle any heavier than the
Gross Vehicle Weight Rating (GVWR), or
either the maximum front or rear Gross Axle
Weight Rating (GAWR). If you do, parts on the
vehicle can break, and it can change the way
your vehicle handles. These could cause you
to lose control and crash. Also, overloading
can shorten the life of the vehicle.

WARNING:
Fuel can spray out on you if you open the fuel cap
too quickly. If you spill fuel and then something
ignites it, you could be badly burned. This spray
can happen if the tank is nearly full, and is more
likely in hot weather. Open the fuel cap slowly and
wait for any hiss noise to stop. Then unscrew the
cap all the way.
Be careful not to spill fuel. Do not top off or overfill the
tank and wait a few seconds after you have finished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. SeeWashing
Your Vehicle on page 6-91.
When replacing the fuel cap, turn it clockwise until it
clicks. Make sure the cap is fully installed. The diagnostic
system can determine if the fuel cap has been left off or
improperly installed. This would allow fuel to evaporate
into the atmosphere. SeeMalfunction Indicator Lamp on
page 4-31.The TIGHTEN GAS CAP message displays on the
Driver Information Center (DIC) if the fuel cap is
not properly installed. SeeDIC Warnings and Messages
on page 4-44for more information.
{
WARNING:
If a fire starts while you are refueling, do not
remove the nozzle. Shut off the flow of fuel by
shutting off the pump or by notifying the station
attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get
the right type. Your dealer/retailer can get one
for you. If you get the wrong type, it may not fit
properly. This may cause the malfunction indicator
lamp to light and may damage the fuel tank and
emissions system. SeeMalfunction Indicator Lamp
on page 4-31.
