Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a
wet road, you cannot stop, accelerate, or turn as
well because your tire-to-road traction is not as
good as on dry roads. And, if your tires do not have
much tread left, you will get even less traction.It is always wise to go slower and be cautious if rain
starts to fall while you are driving. The surface may
get wet suddenly when your reexes are tuned for
driving on dry pavement.
The heavier the rain, the harder it is to see. Even if
your windshield wiper blades are in good shape, a
heavy rain can make it harder to see road signs and
traffic signals, pavement markings, the edge of the
road, and even people walking.
It is wise to keep your windshield wiping equipment
in good shape and keep your windshield washer
uid reservoir lled with washer uid. Replace your
windshield wiper inserts when they show signs of
streaking or missing areas on the windshield,
or when strips of rubber start to separate from
the inserts.

Before changing lanes, check your mirrors.
Then use your turn signal.
Just before you leave the lane, glance quickly
over your shoulder to make sure there is not
another vehicle in your blind spot.
Once you are moving on the freeway, make
certain you allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your
exit, do not, under any circumstances, stop and
back up. Drive on to the next exit.
The exit ramp can be curved, sometimes quite
sharply. The exit speed is usually posted. Reduce
your speed according to your speedometer, not
to your sense of motion. After driving for any
distance at higher speeds, you may tend to think
you are going slower than you actually are.Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such as
after a day’s work — do not plan to make too
many miles that rst part of the journey. Wear
comfortable clothing and shoes you can easily
drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will nd experienced and able service experts
in GM dealerships all across North America. They
will be ready and willing to help if you need it.

1. Remove the Intercooler System pressure cap
when the Intercooler System, including the
upper intercooler hoses, are no longer
hot. Turn the pressure cap slowly
counterclockwise about one-quarter of a turn.
If you hear a hiss, wait for that to stop.
This allows any pressure still left to be vented.
2. Then keep turning the pressure cap slowly,
and remove it.3. Add the proper DEX-COOL
®coolant mixture
to the ll neck, until the coolant reaches the
COLD FILL line on the ll neck.
4. With the Intercooler System pressure cap off,
start the engine and let it run for a couple of
minutes. Then turn the engine off. By this time,
the coolant level inside the ll neck may be
lower. If the level drops to where coolant is no
longer visible in the horizontal tube section
of the ll neck, with the engine off add more of
the DEX-COOL
®coolant mixture to the ll
neck until the level is again visible in the
horizontal tube section.
5. Then replace the pressure cap. Be sure the
pressure cap is hand-tight and fully seated.
If the coolant is not at the proper level
when the system cools down again, see
your dealer.

The tire pressure warning light may come on in
cool weather when the vehicle is rst started, and
then turn off as you start to drive. This could
be an early indicator that the tire pressures are
getting low and need to be inated to the
proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)As an added safety
feature, your vehicle has
been equipped with a
tire pressure monitoring
system (TPMS) that
illuminates a low tire
pressure telltale when
one or more of your tires
is signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inate them to the
proper pressure. Driving on a signicantly
under-inated tire causes the tire to overheat and
can lead to tire failure. Under-ination also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate your vehicle’s tires,
the identication codes will need to be matched to
the new tire/wheel position. The sensors are
matched to the tire/wheel positions in the following
order: driver side front tire, passenger side front
tire, passenger side rear tire, and driver side
rear tire using a TPMS diagnostic tool. See your
GM dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall. If
using this method to match TPMS sensors, the
complete procedure outlined below must be
performed within 15 minutes of the vehicle being
stationary.You will have one minute to match the rst
tire/wheel position, and ve minutes overall, to
match all four tire/wheel positions. If it takes longer
than one minute to match the rst tire and
wheel, or more than ve minutes to match all
four tire/wheel positions, the matching process
stops and you will need to start over.
The TPM matching process is outlined below:
1. Set the parking brake.
2. Press the push-button ignition switch to Acc.
(Off/Accessory).
3. Using the Keyless Access transmitter, lock
and unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the
same time, on the Keyless Access
transmitter. A single horn chirp will sound,
indicating that the TPMS is ready, and
the sensor matching process can begin.
5. Start with the driver’s side front tire.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 78.
Headlamp Wiring
The headlamp wiring is protected by fuses in the
fuse block. An electrical overload will cause
the lamps to turn off. If this happens, have your
headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker. If the wiper motor
overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
