84 Instruments and Controls
Here are three things that some owners ask
about. None of these show a problem with
the fuel gauge:
.It takes a little more or less fuel to fill up
than the gauge indicated. For example,
the gauge indicated the tank was half
full, but it actually took a little more or
less than half the tank's capacity to fill
the tank.
.The gauge moves a little while turning a
corner, speeding up or braking.
.The gauge takes a few seconds to
stabilize after the ignition is turned on,
and goes back to empty when the
ignition is turned off.
Engine Coolant Temperature
Gauge
This gauge shows the engine coolant
temperature.
If the gauge pointer moves into the red
zone, the engine is too hot.This reading indicates the same thing as the
warning light. It means that the engine
coolant has overheated. If the vehicle has
been operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as soon as
possible. See
Engine Overheating 0245 for
more information.
Transmission Temperature Gauge
This gauge will display when the
transmission is experiencing abnormal
temperatures.
As the transmission begins to overheat, the
gauge fills to the right.
The Transmission Temperature Gauge
monitors all aspects of the transmission.
Elevated transmission temperatures may not
be reflected in the Transmission Fluid
Temperature cluster display gauge. Messages will display to indicate the
severity of the overheating. As the gauge
fills up there will be a reduction in vehicle
performance. Once full, the transmission is
overheated and a message to stop safely
will display. Do not drive the vehicle until
the message clears. See
Dual Clutch
Transmission 0195 for more information.
Seat Belt Reminders
Driver Seat Belt Reminder Light
There is a driver seat belt reminder light on
the instrument cluster.
When the vehicle is started, this light
flashes and a chime may come on to remind
the driver to fasten their seat belt.
Then the light stays on solid until the belt is
buckled. This cycle may continue several
times if the driver remains or becomes
unbuckled while the vehicle is moving.

to be replaced, use GM-approved brake pads.
If this is not done, the brake fade warning
system may not function properly.
Stage 1 :The Driver Information Center (DIC)
displays a “Reduce Braking to Avoid
Overheating” message and brake pedal
effort and travel is increased. When the
message displays, the driver should decrease
brake pedal pressure.
Stage 2 : The Driver Information Center
(DIC) displays a “Brakes Overheated Service
Now” message that the brake fluid
temperature is excessive and is about to
boil. The system increases brake pedal effort
and travel, and will also limit vehicle speed.
The driver should immediately start a cool
down lap if on the track. If this message
displays, take the vehicle to be serviced at
your dealer.
Brake Burnishing
New brake pads must be burnished before
racing or other competitive driving.
Caution
Performing the brake burnish procedure
on a base brake system can result in
brake damage.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnish procedure, otherwise damage
may occur to the powertrain/engine. See
New Vehicle Break-In 0189.
Caution
Brake pedal fade will occur during any
track burnish procedure and can cause
brake pedal travel and force to increase.
This could extend stopping distance until
the brakes are fully burnished.
When this procedure is performed as
instructed, it will not damage the brakes.
The brake pads will smoke and produce an
odor. The braking force and pedal travel
may increase. After the procedure, the brake
pads may appear white at the rotor contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation. Brake Burnishing Procedure
This brake burnish procedure should only be
run on vehicles with the J55 Z51 factory
equipped brake system.
1. Using the G-Force Gauge in the HUD display, apply the brakes 25 times
starting at 100 km/h (60 mph) to
50 km/h (30 mph) while decelerating at
0.4 g. See Head-Up Display (HUD) 094.
This is a medium brake application. Drive
for at least 1 km (0.6 mi) between
applying the brakes. This first step may
be skipped if there are more than
320 km (200 mi) on the brake pads.
2. Apply the brakes 25 times starting at 100 km/h (60 mph) to 25 km/h (15 mph)
while decelerating at 0.8 g. This is a hard
brake application without activating the
Antilock Brake System (ABS). Drive for at
least 1 km (0.6 mi) between applications.
Depending on conditions, some increase
in brake pedal travel and brake pedal
force may be experienced.
3. Cool down: Drive at 100 km/h (60 mph) for approximately 15 km (10 mi) without
using the brakes.

184 Driving and Operating
Warning (Continued)
vehicle occupants could drown. Do not
ignore police warnings and be very
cautious about trying to drive through
flowing water.
Caution
Driving through deep puddles or standing
water can cause water to come in
through the engine air intake and
damage the engine. If deep puddles or
standing water cannot be avoided,
proceed with caution and do not exceed
8 km/h (5 mph). Do not drive through
water that may come close to or cover
the vehicle’s underbody.
Hydroplaning
Hydroplaning is dangerous. Water can build
up under the vehicle's tires so they actually
ride on the water. This can happen if the
road is wet enough and you are going fast
enough. When the vehicle is hydroplaning, it
has little or no contact with the road.There is no hard and fast rule about
hydroplaning. The best advice is to slow
down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet weather
driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping equipment in
good shape.
.Keep the windshield washer fluid reservoir
filled.
.Have good tires with proper tread depth.
See
Tires 0259.
.Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through mountains
is different than driving on flat or rolling
terrain. Tips include:
.When driving downhill in D (Drive), the
vehicle may automatically downshift to
assist with speed control.
.A lower gear may also be selected to
provide further speed control.
{Warning
Using the brakes to slow the vehicle on a
long downhill slope can cause brake
overheating, can reduce brake
performance, and could result in a loss of
braking. Shift the transmission to a lower
gear 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. This can
cause overheating of the brakes and loss
of steering assist. Always have the engine
running and the vehicle in gear.
.Drive at speeds that keep the vehicle in
its own lane. Do not swing wide or cross
the center line.
.Be alert on top of hills; something could
be in your lane (e.g., stalled car, crash).
.Pay attention to special road signs (e.g.,
falling rocks area, winding roads, long
grades, passing or no-passing zones) and
take appropriate action.

Caution
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 driving.
Cooling System
The cooling system allows the engine to
maintain the correct working temperature.

{Warning
An underhood electric fan can start up
even when the engine is not running and
can cause injury. Keep hands, clothing,
and tools away from any underhood
electric fan.
{Warning
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
Engine Coolant
The cooling system in the vehicle is filled
with DEX-COOL engine coolant. See
Recommended Fluids and Lubricants0300.
The fluid requires changing at certain
intervals. See Maintenance Schedule 0292.
The following explains the cooling system
and how to check and add coolant when it
is low. If there is a problem with engine
overheating, see Engine Overheating 0245.
What to Use
{Warning
Plain water, or other liquids such as
alcohol, can boil before the proper
coolant mixture will. With plain water or

Vehicle Care 243
Warning (Continued)
the wrong mixture, the engine could get
too hot but there would not be an
overheat warning. The engine could catch
fire and you or others could be burned.
Use a mixture of 40% DEX-COOL coolant and
60% clean, drinkable water. If using this
mixture, nothing else needs to be added.
This mixture:
.Gives freezing protection down to −28 °C
(−18 °F), outside temperature.
.Gives boiling protection up to 129 °C
(265 °F), engine temperature.
.Protects against rust and corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
Caution
Do not use anything other than a mix of
DEX-COOL coolant that meets GM
Standard GMW3420 and clean, drinkable
water. Anything else can cause damage
to the engine cooling system and the
vehicle, which would not be covered by
the vehicle warranty. Never dispose of engine coolant by putting
it in the trash, pouring it on the ground,
or into sewers, streams, or bodies of water.
Have the coolant changed by an authorized
service center, familiar with legal
requirements regarding used coolant
disposal. This will help protect the
environment and your health.
If ambient temperatures are anticipated
below
−28 °C (−18 °F), make sure a proper
mixture ratio of 50% DEX-COOL coolant and
50% clean, drinkable water is used.
Checking Coolant
Be sure the cooling system is cool and that
the vehicle is on a level surface.
Check to see if coolant is visible in the
coolant surge tank. If the coolant inside the
coolant surge tank is boiling, do not do
anything else until it cools down. If coolant
is visible but the coolant level is not at or
above the cold fill line, add a mixture of
40% DEX-COOL coolant and 60% clean,
drinkable water at the coolant recovery
tank, but be sure the cooling system is cool
before this is done. See Engine Overheating
0 245. The surge tank is in the engine
compartment. See
Engine Compartment
Overview 0232.
When the engine is cold, the coolant level
should be at the COLD FILL indicator in the
coolant surge tank.
When the engine is hot, the level could be
higher than the COLD FILL indicator. If the
coolant is below the COLD FILL indicator
when the engine is hot, there could be a
leak in the cooling system.
If the coolant is low, add the coolant or take
the vehicle to your dealer for service.
