2010 GMC TERRAIN cooling

Keys, Doors and Windows 1-5
Remote Vehicle Start
The vehicle may have this feature
that allows you to start the engine
from outside the vehicle.
/(Remote Vehicle Start):
This button will be on the RKE
transmitter if the vehicle has remote
start. To enable and disable remote
start, see “Remote Vehicle Start”
under Vehicle Personalization
on
page 4‑36.
Vehicles with an automatic climate
control system will default to a
heating or cooling mode depending
on the outside temperature during a
remote start. Once the key is turned
to ON/RUN, the system will turn on
at the setting the vehicle was last
set to.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
require a person using remote start
to have the vehicle in view. Check
local regulations for any
requirements. There are other conditions which
can affect the performance of the
transmitter, see
Remote Keyless
Entry (RKE) System
on page 1‑3for additional information.
Starting the Engine Using
Remote Start
To start the engine using the remote
start feature:
1. Press
Qon the RKE transmitter.
2. Press and hold /for about
two seconds. The turn signal
lamps will briefly flash to confirm
the vehicle has been started.
The parking lamps will turn on
and remain on as long as the
engine is running. The vehicle's
doors will be locked.
3. The key must be inserted and turned to ON/RUN before
driving.
The engine will shut off after
10 minutes unless a time
extension is done or the key is
inserted and turned to ON/RUN. Extending Engine Run Time
For a 10-minute extension, repeat
Steps 1 and 2 while the engine is
still running. The remote start can
be extended once.
When the remote start is extended,
the second 10 minutes will start
immediately.
For example, if the engine has been
running for five minutes, and
10 minutes are added, the engine
will run for a total of 15 minutes.
A maximum of two remote starts or
remote start attempts are allowed
between ignition cycles.
The vehicle's ignition switch must
be turned to ON/RUN and then back
to LOCK/OFF using the key, before
the remote start procedure can be
used again.

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, and
you could lose traction and roll
the vehicle over. Do not drive
through rushing water.
Heavy rain can mean flash flooding,
and flood waters demand extreme
caution. Find out how deep the water is
before driving through it. Do not try
it if it is deep enough to cover the
wheel hubs, axles, or exhaust
pipe
—you probably will not get
through. Deep water can damage
the axle and other vehicle parts.
If the 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
tailpipe under water. If the tailpipe is
under water, you will never be able
to start the engine. When going
through water, remember that when
the brakes get wet, it might take
longer to stop. See Driving on Wet
Roads on page 8‑18.
After Off-Road Driving
Remove any brush or debris that
has collected on the underbody,
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, axles,
and exhaust system for damage and
check the fuel lines and cooling
system for any leakage.
The vehicle requires more frequent
service due to off-road use. Refer to
the Maintenance Schedule for
additional information.

Driving and Operating 8-19
.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.
.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
(Continued)
WARNING (Continued)
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.

8-62 Driving and Operating
Leaving After Parking on a Hill
1. Apply and hold the brake pedal.
2. Start the engine.
3. Shift into a gear.
4. Release the parking brake.
5. Let up on the brake pedal.
6. Drive slowly until the trailer isclear of the chocks.
7. Stop and have someone pick up and store the chocks.
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. 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. See Engine Overheating
on page 9‑20.
Trailer Towing
Before pulling a trailer, there are
three important considerations that
have to do with weight:
.The weight of the trailer
.The weight of the trailer tongue
.The total weight on the vehicle's
tires
