4-12 DRIVING YOUR VEHICLE
85Z03-03E
 Tires: They are vitally important to a
safe, trouble-free trip. Is the tread good
enough for long-distance driving? Are
the tires all inflated to the recommended
pressure?
 Weather Forecasts: What’s the weather
outlook along your route? Should you
delay your trip a short time to avoid a
major storm system?
 Maps: Do you have up-to-date maps?Highway HypnosisIs there actually such a condition as “high-
way hypnosis”? Or is it just plain falling
asleep at the wheel? Call it highway hyp-
nosis, lack of awareness, or whatever.
There is something about an easy stretch
of road with the same scenery, along with
the hum of the tires on the road, the drone
of the engine, and the rush of the wind
against the vehicle that can make you
sleepy. Don’t let it happen to you! If it does,
your vehicle can leave the road in less than
a second, and you could crash and be
injured.
What can you do about highway hypnosis?
First, be aware that it can happen.
Then here are some tips:
 Make sure your vehicle is well ventilated,
with a comfortably cool interior.
 Keep your eyes moving. Scan the road
ahead and to the sides. Check your rear-
view mirrors and your instruments fre-
quently. If you get sleepy, pull off the road into a
rest, service or parking area and take a
nap, get some exercise, or both. For
safety, treat drowsiness on the highway
as an emergency.
Hill and Mountain RoadsDriving on steep hills or mountains is differ-
ent from driving in flat or rolling terrain.
If you drive regularly in steep country, or if
you’re planning to visit there, here are
some tips that can make your trips safer
and more enjoyable.
 Keep your vehicle in good shape. Check
all fluid levels and also the brakes, tires,
cooling system and transmission. These
parts can work hard on mountain roads.
 Know how to go down hills. The most
important thing to know is this: let your
engine do some of the slowing down.Shift to a lower gear when you go down
a steep or long hill.
 Know how to go uphill. You may want to
shift down to a lower gear. The lower
gears help cool your engine and trans-
mission, and you can climb the hill bet-
ter.
 Stay in your own lane when driving on
two-lane roads in hills or mountains.
Don’t swing wide or cut across the cen-
ter of the road. Drive at speeds that let
you stay in your own lane.
WARNING
If you don’t shift down, your brakes
could get so hot that they wouldn’t
work well. You would then have poor
braking or even none going down a
hill. You could crash. Shift down to let
your engine assist your brakes on a
steep downhill slope.
WARNING
Coasting downhill in NEUTRAL (N) or
with the ignition off is dangerous.
Your brakes will have to do all the
work of slowing you down. They
could get so hot that they wouldn’t
work well. You would then have poor
braking or even none going down a
hill. You could crash. Always have
your engine running and your vehicle
in gear when you go downhill.

Hydraulic ClutchThere is one reservoir for both the brake
and the hydraulic clutch fluid. See “Brakes”
in this section for more information.
The hydraulic clutch linkage in your vehicle
is self-adjusting. The master cylinder res-
ervoir is filled with hydraulic fluid.
A fluid loss in this system could indicate a
problem. Have the system inspected and
repaired.
When to Check and What to Use
Refer to the Maintenance Schedule to
determine how often you should check the
fluid level and for the proper fluid. See sec-
tion 6.
How to Check and Add Fluid
To check the fluid level, look on the side of
the reservoir. If the fluid level is betweenthe MIN and the MAX marks on the reser-
voir, the fluid level is correct. The reservoir
is located near the back of the engine com-
partment on the driver’s side of the vehicle.
See “Engine Compartment Overview” in
this section for more information on loca-
tion.
Engine CoolantThe following explains your cooling system
and how to add coolant when it is low. If
you have a problem with engine overheat-
ing, see “Engine Overheating” in this sec-
tion.
What to Use
The cooling system in your vehicle is
designed to use either Dex-cool coolant,
which is red in color, or silicate based cool-
ant, which is blue. These two types of cool-
ant are not compatible with each other and
should never be mixed. Therefore, if the
original coolant in your vehicle’s cooling
system was red, then you should use only
Dex-cool coolant for the life of your vehicle.
If the original coolant in your vehicle's cool-
ing system was blue, then you should use
only silicate based coolant for the life of
your vehicle. Even if the cooling system
has been completely drained before a refill,
do not switch types of coolant.Use a 60/40 mixture of clean, drinkable
water and engine coolant which won’t
damage aluminum parts. If another type of
coolant is used, aluminum parts might be
subject to corrosion.
You can also use a recycled coolant with a
complete coolant flush and refill. If you use
this coolant mixture, you don’t need to add
anything else.
A 60/40 mixture of clean, drinkable water
and proper coolant will:
 Give freezing protection down to –33°F
(–36°C).
 Give boiling protection up to 268°F
(131°C).
 Protect against rust and corrosion.
 Help keep the proper engine tempera-
ture.
 Let the warning lights and gauges work
as they should.
For protection in extremely cold weather
conditions, use a 50/50 mixture of clean,
drinkable water and proper coolant.
WARNING
Do not mix Dex-cool and silicate
based coolant in your coolant sys-
tem.
The mixture can damage the cooling
system.

If you have to add coolant more than four
times a year, have your SUZUKI dealer
check your cooling system.Checking Coolant
The engine coolant surge tank is located
on the driver’s side of the engine compart-
ment. See “Engine Compartment Over-
view” in this section for more information
on location.The vehicle must be on a level surface.
When your engine is cold, the coolant level
should be between MAX and MIN mark on
the coolant surge tank. The level rises at
engine operation temperature and drops
again when the engine cools down.
Adding Coolant
If the level falls below the MIN mark, add
the proper coolant mixture at the surge
tank, but only when the engine is cool. If
the surge tank is empty, a special fill proce-
dure is necessary. See “Cooling System”
in this section for instructions on “How to
Add Coolant to the Coolant Surge Tank”.
WARNING
Adding only plain water to your cool-
ing system can be dangerous. Plain
water, or some other liquid such as
alcohol, can boil before the proper
coolant mixture will. Your vehicle’s
coolant warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, your
engine could get too hot but you
wouldn’t get the overheat warning.
Your engine could catch fire and you
or others could be burned. Use a 60/
40 mixture of clean, drinkable water
and the proper coolant.
CAUTION
If you use an improper coolant mix-
ture, your engine could overheat and
be badly damaged. The repair cost
wouldn’t be covered by your war-
ranty. Too much water in the mixture
can freeze and crack the engine, radi-
ator, heater core and other parts.
CAUTION
If you use the proper coolant, you
don’t have to add extra inhibitors or
additives which claim to improve the
system. These can be harmful.
WARNING
Never turn the surge tank pressure
cap – even a little – when the engine
and radiator are hot.
Loosening the surge tank pressure
cap when the engine and radiator are
hot can allow steam and scalding liq-
uids to blow out and burn you badly.
WARNING
Don’t spill coolant on a hot engine.
You can be burned if you spill coolant
on hot engine parts. Coolant con-
tains ethylene glycol, and it will burn
if the engine parts are hot enough.
