A Bluetooth system can use a Bluetooth‐capable cell phone with a Hands‐Free Profile to make and receive phone calls. The system can be used while the key is in the ON/RUN or ACC/ACCESSORY position. The range of the Bluetooth system can be up to 9.1 m (30 ft). Not all phones support all functions, and not all phones work with the in-vehicle Bluetooth system. See www.gm.com/bluetooth for more information on compatible phones. Voice Recognition The Bluetooth system uses voice recognition to interpret voice commands to dial phone numbers and name tags. For additional information, say “Help” while you are in a voice recognition menu.
Noise: Keep interior noise levels to a minimum. The system may not recognize voice commands if there is too much background noise. When to Speak: A short tone sounds after the system responds indicating when it is waiting for a voice command. Wait until the tone and then speak. How to Speak: Speak clearly in a calm and natural voice. Audio System When using the in‐vehicle Bluetooth system, sound comes through the vehicle's front audio system speakers and overrides the audio system. Use the audio system volume knob, during a call, to change the volume level. The adjusted volume level remains in memory for later calls. To prevent missed calls, a minimum volume level is used if the volume is turned down too low.

Driving Information
Distracted Driving Distraction comes in many forms and can take your focus from the task of driving. Exercise good judgment and do not let other activities divert your attention away from the road. Many local governments have enacted laws regarding driver distraction. Become familiar with the local laws in your area. To avoid distracted driving, always keep your eyes on the road, hands on the wheel, and mind on the drive. . Do not use a phone in
demanding driving situations. Use a hands-free method to place or receive necessary phone calls.
. Watch the road. Do not read,
take notes, or look up information on phones or other electronic devices.
. Designate a front seat
passenger to handle potential distractions.
. Become familiar with vehicle
features before driving, such as programming favorite radio stations and adjusting climate control and seat settings. Program all trip information into any navigation device prior to driving.
. Wait until the vehicle is parked
to retrieve items that have fallen to the floor.
. Stop or park the vehicle to tend
to children.
. Keep pets in an appropriate
carrier or restraint.
. Avoid stressful conversations while driving, whether with a passenger or on a cell phone.

Defensive Driving Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear the safety belt. See Safety Belts on page 3‑14. . Assume that other road users
(pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they might do and be ready.
. Allow enough following distance
between you and the driver in front of you. Focus on the task of driving.
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.
Chevrolet Silverado Owner Manual - 2012
Black plate (4,1)
9-4
Driving and Operating
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. 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
Hydraulic Power Steering Your vehicle has hydraulic power steering. It may require maintenance. See Power Steering Fluid Power Steering Fluid on page 10‑28. If power steering assist is lost because the engine stops or the power steering system is not functioning, the vehicle can be steered but may required increased effort. See your dealer if there is a problem. If the vehicle is a hybrid, see the hybrid supplement for more information.
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.
. Antilock Brake System (ABS) allows steering while braking.
Chevrolet Silverado Owner Manual - 2012

Off-Road Recovery
The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips: 1. Ease off the accelerator and then, if there is nothing in the way, steer the vehicle so that it straddles the edge of the pavement.
2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge.
3. Then turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding There are three types of skids that correspond to the vehicle's three control systems: . Braking Skid — wheels are not
rolling.
. Steering or Cornering
Skid — too much speed or steering in a curve causes tires to slip and lose cornering force. . Acceleration Skid — too much
throttle causes the driving wheels to spin.
Driving and Operating
9-5
Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. If the vehicle starts to slide, follow these suggestions: . Ease your foot off the
accelerator pedal and quickly steer the way you want the vehicle to go. The vehicle may straighten out. Be ready for a second skid if it occurs.
. Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt.

Driving and Operating
Try to avoid sudden steering, acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide.
Remember: Antilock brakes help avoid only the braking skid.
Off-Road Driving Four-wheel-drive vehicles can be used for off-road driving. Vehicles without four-wheel drive and vehicles not equipped with All Terrain (AT) or On-Off Road (OOR) tires must not be driven off-road except on a level, solid surface. To contact the tire manufacturer for more information about the original equipment tires, see the Limited Warranty and Owner Assistance Information manual. Controlling the vehicle is the key to successful off-road driving. One of the best ways to control the vehicle is to control the speed.
{ WARNING
When driving off-road, bouncing and quick changes in direction can easily throw you out of position. This could cause you to lose control and crash. You and your passengers should always wear safety belts.
Before Driving Off-Road . Have all necessary maintenance
and service work completed. Fuel the vehicle, fill fluid levels, and check inflation pressure in all tires, including the spare, if equipped.
. Read all the information about
four-wheel-drive vehicles in this manual.

For more information about loading the vehicle, see Vehicle Load Limits and Tires. Environmental Concerns . Always use established trails,
roads, and areas that have been set aside for public off-road recreational driving and obey all posted regulations.
. Do not damage shrubs, flowers,
trees, or grasses or disturb wildlife.
. Do not park over things that
burn. See Parking Over Things that Burn.
. Make sure all underbody
shields, if equipped, are properly attached.
. Know the local laws that apply to
off-road driving.
To gain more ground clearance if needed, it may be necessary to remove the front fascia lower air dam. Notice: Operating the vehicle for extended periods without the front fascia lower air dam installed can cause improper air flow to the engine. Re‐attach the front fascia air dam after off-road driving.
Loading the Vehicle for Off-Road Driving
{ WARNING
. Unsecured cargo on the load
floor can be tossed about when driving over rough terrain. You or your passengers can be struck by flying objects. Secure the cargo properly.
. Keep cargo in the cargo area as far forward and as low as possible. The heaviest things should be on the floor, forward of the rear axle.
. Heavy loads on the roof raise the vehicle's center of gravity, making it more likely to roll over. You can be seriously or fatally injured if the vehicle rolls over. Put heavy loads inside the cargo area, not on the roof.

Driving on Hills Driving safely on hills requires good judgment and an understanding of what the vehicle can and cannot do.
{ WARNING
If the vehicle has the two‐speed automatic transfer case, shifting the transfer case to N (Neutral) can cause your vehicle to roll even if the transmission is in P (Park) for an automatic transmission or any gear position for a manual transmission. This is because the N (Neutral) position on the transfer case overrides the transmission. You or someone else could be injured. If leaving the vehicle, set the parking brake and shift the transmission to P (Park) for an automatic transmission or any gear position for a manual transmission. Shift the transfer case to any position but N (Neutral).
Before driving on a hill, assess the steepness, traction, and obstructions. If the terrain ahead cannot be seen, get out of the vehicle and walk the hill before driving further. When driving on hills: . Use a low gear and keep a firm
grip on the steering wheel.
. Maintain a slow speed. . When possible, drive straight up
or down the hill.
. Slow down when approaching
the top of the hill.
. Use headlamps even during the
day to make the vehicle more visible.
{ WARNING
Driving to the top of a hill at high speed can cause an accident. There could be a drop-off, embankment, cliff, or even another vehicle. You could be seriously injured or killed. As you near the top of a hill, slow down and stay alert.
. Never go downhill forward or
backward with either the transmission or transfer case in N (Neutral). The brakes could overheat and you could lose control.

Driving and Operating
9-9
Never try to turn the vehicle around. If the hill is steep enough to stall the vehicle, it is steep enough to cause it to roll over. If you cannot make it up the hill, back straight down the hill. Never back down a hill in N (Neutral) using only the brake. The vehicle can roll backward quickly and you could lose control. If driving downhill when the vehicle stalls, shift to a lower gear, release the parking brake, and drive straight down the hill.
{ WARNING
{ WARNING
If the vehicle has the two‐speed automatic transfer case, shifting the transfer case to N (Neutral) can cause your vehicle to roll even if the transmission is in P (Park). This is because the N (Neutral) position on the transfer case overrides the transmission. You or someone else could be injured. If leaving the vehicle, set the parking brake and shift the transmission to P (Park). Shift the transfer case to any position but N (Neutral).
. When driving down a hill, keep
the vehicle headed straight down. Use a low gear because the engine will work with the brakes to slow the vehicle and help keep the vehicle under control.
Heavy braking when going down a hill can cause your brakes to overheat and fade. This could cause loss of control and you or others could be injured or killed. Apply the brakes lightly when descending a hill and use a low gear to keep vehicle speed under control.
If the vehicle stalls on a hill: 1. Apply the brakes to stop the vehicle, and then apply the parking brake.
2. Shift into P (Park) for an
automatic transmission or 1 (First) for a manual transmission and then restart the engine.
If driving uphill when the vehicle stalls, shift to R (Reverse), release the parking brake, and back straight down.

3.
If the vehicle cannot be restarted after stalling, set the parking brake, shift an automatic transmission into P (Park) or a manual transmission into 1 (First), and turn the vehicle off. 3.1. Leave the vehicle and
seek help.
3.2. Stay clear of the path the
vehicle would take if it rolled downhill.
. Avoid turns that take the vehicle
across the incline of the hill. A hill that can be driven straight up or down might be too steep to drive across. Driving across an incline puts more weight on the downhill wheels which could cause a downhill slide or a rollover.
. Surface conditions can be a
problem. Loose gravel, muddy spots, or even wet grass can cause the tires to slip sideways, downhill. If the vehicle slips sideways, it can hit something that will trip it – a rock, a rut, etc. – and roll over.
. Hidden obstacles can make the
steepness of the incline more severe. If a rock is driven across with the uphill wheels, or if the downhill wheels drop into a rut or depression, the vehicle can tilt even more. If an incline must be driven across, and the vehicle starts to slide, turn downhill. This should help straighten out the vehicle and prevent the side slipping.
{ WARNING
Getting out of the vehicle on the downhill side when stopped across an incline is dangerous. If the vehicle rolls over, you could be crushed or killed. Always get out on the uphill side of the vehicle and stay well clear of the rollover path.
Driving in Mud, Sand, Snow, or Ice Use a low gear when driving in mud – the deeper the mud, the lower the gear. Keep the vehicle moving to avoid getting stuck. Traction changes when driving on sand. On loose sand, such as on beaches or sand dunes, the tires tend to sink into the sand. This affects steering, accelerating, and braking. Drive at a reduced speed and avoid sharp turns or abrupt maneuvers.
Chevrolet Silverado Owner Manual - 2012
Black plate (11,1)
Traction is reduced on hard packed snow and ice and it is easy to lose control. Reduce vehicle speed when driving on hard packed snow and ice.
{ WARNING
Driving on frozen lakes, ponds, or rivers can be dangerous. Ice conditions vary greatly and the vehicle could fall through the ice; you and your passengers could drown. Drive your vehicle on safe surfaces only.
Driving and Operating
9-11
Driving in Water
{ WARNING
Driving through rushing water can be dangerous. Deep water can sweep your vehicle downstream and you and your passengers could drown. If it is only shallow water, it can still wash away the ground from under your tires. Traction could be lost, and the vehicle could roll over. Do not drive through rushing water.
Notice: Do not drive through standing water if it is deep enough to cover the wheel hubs, axles or exhaust pipe. Deep water can damage the axle and other vehicle parts. If the standing water is not too deep, drive slowly through it. At faster speeds, water splashes on the ignition system and the vehicle can stall. Stalling can also occur if you get the exhaust pipe under water.
While the exhaust pipe is under water, you will not be able to start the engine. When going through water, the brakes get wet, and it might take longer to stop. See Driving on Wet Roads. After Off-Road Driving Remove any brush or debris that has collected on the underbody or chassis, or under the hood. These accumulations can be a fire hazard. After operation in mud or sand, have the brake linings cleaned and checked. These substances can cause glazing and uneven braking. Check the body structure, steering, suspension, wheels, tires, and exhaust system for damage and check the fuel lines and cooling system for any leakage. More frequent maintenance service is required. Refer to the Maintenance Schedule for more information.

Driving on Wet Roads Rain 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.
(Continued)
WARNING (Continued)
Flowing or rushing water creates strong forces. Driving through flowing water could cause the 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.
Hydroplaning Hydroplaning is dangerous. Water can build up under the 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 the 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 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. See Tires on page 10‑57. Turn off cruise control.
Highway Hypnosis Always be alert and pay attention to your surroundings while driving. If you become tired or sleepy, find a safe place to park the vehicle and rest. Other driving tips include: . Keep the vehicle well ventilated. . Keep the interior temperature cool.

. Stay in your own lane. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane.
. Be alert on top of hills;
something could be in your lane (stalled car, accident).
. Pay attention to special road
signs (falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action.
. Keep your eyes moving — scan the road ahead and to the sides.
. Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips for driving in these conditions include: . Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and transmission.
. Shift to a lower gear when going
down steep or long hills.
{ WARNING
If you do not shift down, the brakes could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let the engine assist the brakes on a steep downhill slope.
{ WARNING
Coasting downhill in N (Neutral) or with the ignition off is dangerous. The brakes will have to do all the work of slowing down and they could get so hot that they would not work well. You would then have poor braking or even none going down a hill. You could crash. Always have the engine running and the vehicle in gear when going downhill.

Winter Driving
Driving on Snow or Ice Drive carefully when there is snow or ice between the tires and the road, creating less traction or grip. Wet ice can occur at about 0°C (32°F) when freezing rain begins to fall, resulting in even less traction.
