If the overheat warning is displayed with no sign of
steam:1. Turn the air conditioning off.
2. Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as
necessary.
3. In heavy traffic, let the engine idle in N (Neutral) while stopped. If it safe to do so, pull off the road,
shift to P (Park) or N (Neutral) and let the
engine idle.
If the temperature overheat gauge is no longer in the
overheat zone or an overheat warning no longer
displays, the vehicle can be driven. Continue to drive
the vehicle slow for about 10 minutes. Keep a safe
vehicle distance from the vehicle in front. If the warning
does not come back on, continue to drive normally.
If the warning continues, pull over, stop, and park the
vehicle right away.
If there is no sign of steam, idle the engine for
three minutes while parked. If the warning is still
displayed, turn off the engine until it cools down. Also,
see "Overheated Engine Protection Operating Mode"
next in this section.Overheated Engine Protection
Operating Mode
If an overheated engine condition exists and the
message ENGINE OVERHEATED STOP ENGINE
is displayed, an overheat protection mode which
alternates firing groups of cylinders helps prevent
engine damage. In this mode, you will notice a loss in
power and engine performance. This operating mode
allows your vehicle to be driven to a safe place in an
emergency. Driving extended miles (km) and/or towing
a trailer in the overheat protection mode should be
avoided.
Notice: After driving in the overheated engine
protection operating mode, to avoid engine damage,
allow the engine to cool before attempting any
repair. The engine oil will be severely degraded.
Repair the cause of coolant loss, change the oil
and reset the oil life system. See Engine Oil
on
page 6‑15.

Insuring Your Vehicle
Protect your investment in your GM vehicle with
comprehensive and collision insurance coverage. There
are significant differences in the quality of coverage
afforded by various insurance policy terms. Many
insurance policies provide reduced protection to your
GM vehicle by limiting compensation for damage
repairs by using aftermarket collision parts. Some
insurance companies will not specify aftermarket
collision parts. When purchasing insurance, we
recommend that you ensure that your vehicle will be
repaired with GM original equipment collision parts.
If such insurance coverage is not available from your
current insurance carrier, consider switching to another
insurance carrier.
If your vehicle is leased, the leasing company may
require you to have insurance that ensures repairs with
Genuine GM Original Equipment Manufacturer (OEM)
parts or Genuine Manufacturer replacement parts. Read
your lease carefully, as you may be charged at the end
of your lease for poor quality repairs.
If a Crash Occurs
If there has been an injury, call emergency services for
help. Do not leave the scene of a crash until all matters
have been taken care of. Move the vehicle only if its
position puts you in danger, or you are instructed to
move it by a police officer.Give only the necessary information to police and other
parties involved in the crash.
For emergency towing see
Roadside Service
on
page 8‑7.
Gather the following information:
.Driver's name, address, and telephone number
.Driver's license number
.Owner's name, address, and telephone number
.Vehicle license plate number
.Vehicle make, model, and model year
.Vehicle Identification Number (VIN)
.Insurance company and policy number
.General description of the damage to the other
vehicle
Choose a reputable repair facility that uses quality
replacement parts. See “Collision Parts”earlier in this
section.
If the airbag has inflated, see What Will You See After
an Airbag Inflates? on page 2‑62.
