2010 GMC YUKON HYBRID warning

WARNING: (Continued)
Battery fluid contains acid that can burn you.
Do not get it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
{WARNING:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.6. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) goes to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a
heavy, unpainted metal engine part or a solid
engine ground.
Do not connect positive (+) to negative (−) or you
will get a short that would damage the battery and
maybe other parts too. Do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.
7. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead
battery. Use a remote positive (+) if the vehicle
has one.

When to Check
Check your tires once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure. You cannot tell if your tires are properly
inflated simply by looking at them. Radial tires may look
properly inflated even when they're underinflated.
Check the tire's inflation pressure when the tires are
cold. Cold means your vehicle has been sitting for at
least three hours or driven no more than 1 mile (1.6 km).
Remove the valve cap from the tire valve stem. Press
the tire gage firmly onto the valve to get a pressure
measurement. If the cold tire inflation pressure matches
the recommended pressure on the tire and loading
information label, no further adjustment is necessary.
If the pressure is low, add air until you reach the
recommended amount.
If you overfill the tire, release air by pushing on the
metal stem in the center of the tire valve. Recheck the
tire pressure with the tire gage.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly. The TPMS
sensors monitor the air pressure in the vehicle's tires
and transmit the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS will illuminate the
low tire pressure warning
symbol located on the
instrument panel cluster.
At the same time a message to check the pressure
in a specific tire appears on the Driver Information
Center (DIC) display. The low tire pressure warning
light and the DIC warning message come on at
each ignition cycle until the tires are inflated to
the correct inflation pressure. Using the DIC, tire
pressure levels can be viewed by the driver. For
6-29

additional information and details about the DIC
operation and displays seeDIC Warnings and
Messages
on page 4‑12. Also, see “DIC Operation and
Displays” in the Index of the owner manual for more
information.
The low tire pressure warning light may come on in cool
weather when the vehicle is first started, and then turn
off as you start to drive. This could be an early indicator
that the air pressure in the tire(s) are getting low and
need to be inflated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle's original
equipment tires and the correct inflation pressure for
your vehicle's tires when they are cold. See “Loading
Your Vehicle” for an example of the Tire and Loading
Information label and its location on your vehicle.
Also see Inflation - Tire Pressure on page 6‑28. Your vehicle's TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. See
“Tire Inspection and Rotation” and
“Tires” in the Index of the owner manual for more
information.
Notice: Using non‐approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using an
incorrect tire sealant is not covered by the vehicle
warranty. Always use the GM approved tire sealant
available through your dealer/retailer.
Your vehicle, when new, included a factory‐installed
Tire Sealant and Compressor Kit. This kit uses a
GM approved liquid tire sealant. See Tire Sealant and
Compressor Kit (Without Selector Switch)
on
page 6‑35or Tire Sealant and Compressor Kit
(With Selector Switch) on page 6‑45.
6-30

TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of
the TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
flashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until
the problem is corrected. Some of the conditions that
can cause the malfunction light and DIC message to
come on are:
.The TPMS sensor matching process was started
but not completed or not completed successfully
after rotating the vehicle's tires. The DIC message
and TPMS malfunction light should go off once the
TPMS sensor matching process is performed
successfully. See“TPMS Sensor Matching
Process” later in this section.
.One or more TPMS sensors are missing or
damaged. The DIC message and the TPMS
malfunction light should go off when the TPMS
sensors are installed and the sensor matching
process is performed successfully. See your
dealer/retailer for service.
.Replacement tires or wheels do not match your
vehicle's original equipment tires or wheels.
Tires and wheels other than those recommended
for your vehicle could prevent the TPMS from
functioning properly. See “Buying New Tires”in
the Index of the owner manual.
.Operating electronic devices or being near facilities
using radio wave frequencies similar to the TPMS
could cause the TPMS sensors to malfunction.
If the TPMS is not functioning it cannot detect or signal
a low tire condition. See your dealer/retailer for service
if the TPMS malfunction light and DIC message comes
on and stays on.

Tire Chains
{WARNING:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle without
the proper amount of clearance can cause
damage to the brakes, suspension, or other
vehicle parts. The area damaged by the tire
chains could cause you to lose control of the
vehicle and you or others may be injured in a
crash. Use another type of traction device
only if its manufacturer recommends it for use
on the vehicle and tire size combination and
road conditions. Follow that manufacturer's
instructions. To help avoid damage to the vehicle,
drive slowly, re‐adjust or remove the device if it
is contacting the vehicle, and do not spin the
wheels. If you do find traction devices that will fit,
install them on the rear tires.
If a Tire Goes Flat
Your vehicle has a tire inflator kit. There is no spare tire,
no tire changing equipment, and no place to store a tire.
It is unusual for a tire to blow out while you are driving,
especially if you maintain your tires properly. If air goes
out of a tire, it is much more likely to leak out slowly.
But, if you should ever have a blow out, here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire creates a drag that pulls
the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blow out, particularly on a curve, acts much like a
skid and may require the same correction you would
use in a skid. In any rear blow out, remove your foot
from the accelerator pedal. Get the vehicle under
control by steering the way you want the vehicle to go.
It may be very bumpy and noisy, but you can still steer.
Gently brake to a stop, well off the road if possible.
6-34

If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place and stopping.
Then do this:1. Turn on the hazard warning flashers.
2. Park your vehicle. Set the parking brake firmly and put the shift lever in PARK (P).
3. Turn off the engine.
4. Inspect the flat tire.
If the tire has been separated from the wheel or has
damaged sidewalls or large tears that allow rapid air
loss, call a tire repair facility. See “Roadside Assistance
Program” in the Index of the owner manual.
If the flat tire is due to a slow leak caused by a nail or
other similar road hazard, the tire inflator kit may be
used to repair the damaged tire temporarily. The kit
uses a liquid tire sealant to seal small punctures in the
tread area of the tire.
After repairing a tire with the tire inflator kit, take your
vehicle to an authorized retailer to have the tire
inspected and repaired as soon as possible. The tire
sealant is a temporary repair only. See Tire Sealant
and Compressor Kit (Without Selector Switch)
on
page 6‑35or Tire Sealant and Compressor Kit
(With Selector Switch) on page 6‑45.

{WARNING:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains
Carbon Monoxide (CO) which cannot be seen or
smelled. It can cause unconsciousness and even
death. Never run the engine in an enclosed area
that has no fresh air ventilation. For more
information, see”Engine Exhaust” in the owner
manual.
{WARNING:
Over-inflating a tire could cause the tire to rupture
and you or others could be injured. Be sure to
read and follow the tire sealant and compressor
kit instructions and inflate the tire to its
recommended pressure. Do not exceed the
recommended pressure.
