2011 CHEVROLET HHR brakes

Black plate (21,1)Chevrolet HHR Owner Manual - 2011
Ignition Positions
The ignition switch has four different positions.
In order to shift out of P (Park), the ignition must be in
ON/RUN or ACC/ACCESSORY and the brake pedal
must be applied.
Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer. 9(STOPPING THE ENGINE/LOCK/OFF):
When the
vehicle is stopped, turn the ignition switch to LOCK/OFF
to turn the engine off. Retained Accessory Power (RAP)
will remain active. See Retained Accessory Power
(RAP) on page 3‑24.
This position locks the steering column when the key is
removed. The key can only be removed in LOCK/OFF.
On vehicles with a manual transmission, the ignition
switch can be turned to LOCK/OFF in any shift lever
position.
Do not turn the engine off when the vehicle is moving.
This will cause a loss of power assist in the brake and
steering systems and disable the airbags.
In an emergency:
1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This may deplete
power assist, requiring increased brake pedal
force.
2. Shift the vehicle to neutral. This can be done while the vehicle is moving. After shifting to neutral,
firmly apply the brakes and steer the vehicle to a
safe location.

WARNING: (Continued)
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). SeeShifting Into
Park (Automatic Transmission)
on page 3‑31.
If you are pulling a trailer, see Towing a Trailer
(Automatic Transmission)
on page 5‑31or
Towing a Trailer (Manual Transmission)
on
page 5‑37
.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes first and then press the shift
lever button before the vehicle can shift from P (Park)
when the ignition key is in ON/RUN. If the vehicle
cannot shift out of P (Park), ease pressure on the shift
lever and push the shift lever all the way into P (Park)
as you maintain brake application. Then press the shift
lever button and then move the shift lever into another
gear. See Shifting Out of Park (Automatic Transmission)
on page 3‑33. R (Reverse):
Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock your vehicle back and forth to get out of snow,
ice, or sand without damaging the transmission, see If
Your Vehicle is Stuck in Sand, Mud, Ice, or Snow
on
page 5‑21.
N (Neutral): In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
3-27

Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle.
D (Drive): This position is for normal driving with the
automatic transmission. It provides the best fuel
economy. If you need more power for passing and
you are:
.Going less than about 55 km/h (35 mph), push the
accelerator pedal about halfway down.
.Going about 55 km/h (35 mph), push the
accelerator all the way down.
Downshifting the transmission in slippery road
conditions could result in skidding, see “Skidding”under
Loss of Control on page 5‑14.
I (Intermediate): This position is also used for normal
driving. However, it reduces vehicle speed without using
the brakes for slight downgrades where the vehicle
would otherwise accelerate due to steepness of grade.
If constant upshifting or downshifting occurs while
driving up steep hills, this position can be used to
prevent repetitive types of shifts. You might choose
I (Intermediate) instead of D (Drive) when driving on
hilly, winding roads and when towing a trailer, so that
there is less shifting between gears. PERFORMANCE SHIFTING:
If the vehicle has this
feature, it can detect a change in driving patterns while
in the Intermediate position. If you make an aggressive
driving maneuver, the vehicle's transmission
automatically shifts to the lowest possible gear to
maximize vehicle performance. The vehicle will
automatically return to normal operation when you
return to normal driving patterns.
L (Low): This position reduces vehicle speed more than
I (Intermediate) without actually using the brakes. You
can use it on very steep hills, or in deep snow or mud.
If the shift lever is put in L (Low), the transmission will
not shift into L (Low) until the vehicle is going slowly
enough.
Notice: Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator pedal
may damage the transmission. The repair will not be
covered by the vehicle warranty. If you are stuck, do
not spin the tires. When stopping on a hill, use the
brakes to hold the vehicle in place.

Setting Cruise Control
If the cruise button is on when not in use, it could get
bumped and go into cruise when not desired. Keep the
cruise control switch off when cruise is not being used.1. Press
Ito turn cruise control on. The indicator
light on the button comes on.
2. Get to the desired speed.
3. Press the SET− control button and release it. The
CRUISE ENGAGED message appears on the
Driver Information Center (DIC) to show the system
is engaged.
4. Take your foot off the accelerator pedal.
When the brakes are applied or the clutch pedal is
used, the cruise control is disengaged.
If the vehicle is in cruise control and the Traction
Control System (TCS) begins to limit wheel spin, the
cruise control automatically disengages. See Traction
Control System (TCS)
on page 5‑8and Enhanced
Traction System (ETS)on page 5‑10. When road
conditions allow, the cruise control can be used again.
Resuming a Set Speed
If the cruise control is set at a desired speed and then
the brakes are applied, the cruise control is disengaged
without erasing the set speed from memory.
Once the vehicle speed reaches about 40 km/h
(25 mph) or more, press the +RES button on the
steering wheel. The vehicle returns to the previous set
speed and stays there.
Increasing Speed While Using Cruise
Control
If the cruise control system is already activated,
.Press and hold the +RES button on the steering
wheel until the desired speed is reached, then
release it.
.To increase vehicle speed in small amounts, press
the +RES button. Each time this is done, the
vehicle goes about 1.6 km/h (1 mph) faster.

Reducing Speed While Using Cruise
Control
If the cruise control system is already activated,
.Press and hold the SET–button on the steering
wheel until the desired lower speed is reached,
then release it.
.To slow down in small amounts, press the
SET– button on the steering wheel briefly.
Each time this is done, the vehicle goes about
1.6 km/h (1 mph) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle
speed. When you take your foot off the pedal, the
vehicle will slow down to the previous set cruise speed.
Using Cruise Control on Hills
How well the cruise control works on hills depends upon
the vehicle speed, load and the steepness of the hills.
When going up steep hills, the accelerator pedal might
need to be applied to maintain the vehicle speed. When
going downhill, the brake might need to be applied or
the vehicle might have to be shifted to a lower gear to
keep the vehicle speed down. When the brakes are
applied the cruise control is disengaged.
Ending Cruise Control
There are two ways to end cruise control:
.To disengage cruise control; step lightly on the
brake pedal or the clutch pedal if the vehicle has a
manual transmission.
.To turn off the cruise control, pressIon the
steering wheel.
Erasing Speed Memory
The cruise control set speed is erased from memory by
pressing the
Ibutton or if the ignition is turned off.

Antilock Brake System (ABS)
Warning Light
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine is
started.
If it does not, have the vehicle serviced by your dealer.
If the system is working normally the indicator light then
goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on, the
vehicle does not have antilock brakes and there is a
problem with the regular brakes. See Brake System
Warning Light on page 4‑29.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages
on page 4‑40for all
brake related DIC messages.
Enhanced Traction System (ETS)
Indicator/Warning Light
For vehicles with the
Enhanced Traction
System (ETS), this light
serves as an indicator
and warning light.
This light comes on briefly while the engine is started.
If it does not, have the vehicle serviced by your dealer.
If the system is working normally the indicator light then
goes off.
If the indicator/warning light is on and not flashing, the
ETS system could have been disabled. Check all
related Driver Information Center (DIC) messages to
determine whether the system has been turned off or if
the system is not working properly and the vehicle
requires service. If the ETS has been disabled, wheel
spin is not limited.
If the indicator/warning light is on and flashing, the ETS
is actively working. The LOW TRACTION DIC message
also appears when the system is actively limiting
wheel spin.

For persons under 21, it is against the law in every
U.S. state to drink alcohol. There are good medical,
psychological, and developmental reasons for
these laws.
The obvious way to eliminate the leading highway
safety problem is for people never to drink alcohol and
then drive.
Medical research shows that alcohol in a person's
system can make crash injuries worse, especially
injuries to the brain, spinal cord, or heart. This means
that when anyone who has been drinking—driver or
passenger —is in a crash, that person's chance of
being killed or permanently disabled is higher than if
the person had not been drinking.
Control of a Vehicle
The following three systems help to control the vehicle
while driving —brakes, steering, and accelerator. At
times, as when driving on snow or ice, it is easy to ask
more of those control systems than the tires and road
can provide. Meaning, you can lose control of the
vehicle. See Traction Control System (TCS)
on
page 5‑8, Enhanced Traction System (ETS)on
page 5‑10, and Electronic Stability Control (ESC)on
page 5‑6.
Adding non‐dealer/non‐retailer accessories can affect
vehicle performance. See Accessories and
Modifications on page 6‑3.
Braking
See Brake System Warning Light on page 4‑29.
Braking action involves perception time and reaction
time. Deciding to push the brake pedal is perception
time. Actually doing it is reaction time.
Average reaction time is about three‐fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three‐fourths of a
second, a vehicle moving at 100 km/h (60 mph) travels
20 m (66 feet). That could be a lot of distance in an
emergency, so keeping enough space between the
vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement or
gravel; the condition of the road, whether it is wet, dry,
or icy; tire tread; the condition of the brakes; the weight
of the vehicle; and the amount of brake force applied.
Avoid needless heavy braking. Some people drive in
spurts, heavy acceleration followed by heavy braking,
rather than keeping pace with traffic. This is a mistake.
The brakes might not have time to cool between hard
stops. The brakes will wear out much faster with a lot of
heavy braking. Keeping pace with the traffic and
5-3

Black plate (4,1)Chevrolet HHR Owner Manual - 2011
allowing realistic following distances eliminates a lot of
unnecessary braking. That means better braking and
longer brake life.
If the engine ever stops while the vehicle is being
driven, brake normally but do not pump the brakes.
If the brakes are pumped, the pedal could get harder to
push down. If the engine stops, there will still 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.
If the vehicle has Electronic Stability Control (ESC) and
the 2.0L turbocharged engine, it also has a hydraulic
brake boost feature which supplements the power brake
system to maintain consistent brake performance under
conditions of low brake booster vacuum. Low brake
booster vacuum conditions can include initial start up
after the vehicle has been parked for several hours,
very frequent brake stops, or high altitude driving. When
hydraulic brake boost is active, minor brake pulsation or
movement might be felt but this is normal. If brake pedal
feel changes or the brake pedal feels hard to push, the
system might not be receiving the intended brake boost
and the SVC BRAKE SYSTEM DIC message may be
displayed.
Adding non‐dealer accessories can affect vehicle
performance. SeeAccessories and Modifications
on
page 6‑3.
Antilock Brake System (ABS)
The vehicle might have the Antilock Brake
System (ABS), an advanced electronic braking
system that helps prevent a braking skid.
If the vehicle has ABS,
this warning light on the
instrument panel comes
on briefly when the
vehicle is started.
When the engine is started, or when the vehicle begins
to drive away, ABS checks itself. A momentary motor or
clicking noise might be heard while this test is going on,
and it might even be noticed that the brake pedal
moves or pulses a little. This is normal.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that the wheels are slowing down.
If one of the wheels is about to stop rolling, the
computer will separately work the brakes at each wheel.
