2010 CHEVROLET HHR transmission fluid

AUTO (Automatic) LIGHTS OFF
This message displays if the automatic headlamp
system is disabled with the headlamp switch. See
Automatic Headlamp System
on page 4‑12for more
information.
AUTO (Automatic) LIGHTS ON
This message displays if the automatic headlamp
system is enabled with the headlamp switch. See
Automatic Headlamp System
on page 4‑12for more
information.
BRAKE FLUID
This message displays, while the ignition is on, when
the brake fluid level is low. The brake system warning
light on the instrument panel cluster also comes on.
See Brake System Warning Light
on page 4‑30for
more information. Have the brake system serviced by
your dealer/retailer as soon as possible.
CHANGE OIL SOON
This message displays when the life of the engine oil
has expired and it should be changed.
When this message is acknowledged and cleared from
the display, the engine oil life system must still be reset
separately. See Engine Oil Life System
on page 6‑23andScheduled Maintenanceon page 7‑3for more
information.
CHECK GAS CAP
This message displays if the fuel cap has not been fully
tightened. Recheck the fuel cap to make sure that it is
on properly. A few driving trips with the cap properly
installed should turn the message off.
COMPETITIVE MODE
If your vehicle has this feature, this message displays
when the Competitive Driving mode is selected. The
Traction Control System (TCS) will not be operating
while in the Competitive Driving mode and the ESC/
TCS light on the instrument panel cluster will be on
solid. Adjust your driving accordingly. See Traction
Control System (TCS)
on page 5‑9, Electronic
Stability Control (ESC)on page 5‑6, and Electronic
Stability Control (ESC)/Traction Control System (TCS)
Indicator/Warning Light
on page 4‑33for more
information.
COOLING MODE ON
This message may display on some vehicles. Under
severe conditions, hot ambient temperatures, steep
grades, and towing, your vehicle may experience more
transmission shifting. This is temporary and normal
under these conditions. This does not require engine or
transmission service.

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.
.Going down steep or long hills, shift to a
lower gear.
{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.
.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.
.Top of hills: Be alert—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.

Maintenance When Trailer Towing
The vehicle needs service more often when pulling a
trailer. See this manual's Maintenance Schedule or
Index for more information. Things that are especially
important in trailer operation are automatic transmission
fluid, engine oil, axle lubricant, belts, cooling system
and brake system. It is a good idea to inspect these
before and during the trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
The cooling system may temporarily overheat during
severe operating conditions. SeeEngine Overheating
on page 6‑34.
Towing a Trailer
(Manual Transmission)
Do not tow a trailer if the vehicle is equipped with a
manual transmission.

To inspect or replace the filter, do the following:1. Remove the screws that hold the housing and cover together and lift off the cover.
2. Inspect or replace the engine air cleaner/filter.
3. Reverse the steps to reinstall the system. Be sure to reinstall the housing tightly.
{WARNING:
Operating the engine with the air cleaner/filter off
can cause you or others to be burned. The air
cleaner not only cleans the air; it helps to stop
flames if the engine backfires. Use caution when
working on the engine and do not drive with the
air cleaner/filter off.
Notice: If the air cleaner/filter is off, dirt can easily
get into the engine, which could damage it. Always
have the air cleaner/filter in place when you are
driving.
Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take your vehicle to a dealer/
retailer and have it repaired as soon as possible.
Change the fluid and filter at the intervals listed in the
Maintenance Schedule. See Scheduled Maintenance
on page 7‑3. Be sure to use the transmission fluid
listed in Recommended Fluids and Lubricantson
page 7‑10.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑10.
6-27

Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to a
dealer/retailer for service. Have it repaired as soon as
possible. You may also have the fluid level checked
by your dealer/retailer when the oil is changed. See
Recommended Fluids and Lubricants
on page 7‑10for
the proper fluid to use.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. This system does not have its own
reservoir. It receives fluid from the brake master
cylinder reservoir.
See Brakes
on page 6‑37for more information.
Cooling System
The Cooling System allows the engine to maintain the
correct working temperature.
A. Pressure Cap
B. Coolant Recovery Tank
C. Electric Engine Cooling Fan

Brakes
Brake Fluid
The brake master cylinder and, on manual transmission
vehicles, the clutch hydraulic system use the same
reservoir. SeeEngine Compartment Overview
on
page 6‑16for the location of the reservoir. The
reservoir is filled with DOT 3 brake fluid.
There are only two reasons why the brake fluid level in
the reservoir might go down:
.The brake fluid level goes down because of
normal brake lining wear. When new linings are
installed, the fluid level goes back up.
.A fluid leak in the brake and/or clutch hydraulic
system can also cause a low fluid level. Have the
brake and/or clutch hydraulic system fixed, since a
leak means that sooner or later the brakes and/or
clutch will not work well. Do not top off the brake/clutch fluid. Adding fluid does
not correct a leak. If fluid is added when the brake
linings are worn, there will be too much fluid when new
brake linings are installed. Add or remove fluid, as
necessary, only when work is done on the brake/clutch
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 and/or clutch hydraulic system.
When the brake fluid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 4‑30.
