3. Fill the coolant surge tank with the proper mixture to the
indicated level mark.
4. With the coolant surge tank pressure cap off, start the
engine, switch off the A/C and
let the engine run until the
upper radiator hose can be felt
getting hot. Watch out for the
engine cooling fan. By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
mixture to the coolant surge
tank until the level reaches the
indicated level mark.
5. Replace the pressure cap. Be sure the pressure cap is
hand-tight.

proper level when the system
cools down again, see your
dealer.
Caution
If the pressure cap is not tightly
installed, coolant loss and engine
damage may occur. Be sure the
cap is properly and tightly
secured.

318 Vehicle Care
Caution
If the vehicle is equipped with
195/65R15 or 205/55R16 size
tires, use tire chains only where
legal and only when necessary.
Use low profile chains that add no
more than 12 mm thickness to the
tire tread and inner sidewall. Use
chains that are the proper size for
the tires. Install them on the tires
of the front axle. Do not use
chains on the tires of the rear
axle. Tighten them as tightly as
possible with the ends securely
fastened. Drive slowly and follow
the chain manufacturer's
instructions. If the chains contact
the vehicle, stop and retighten
them. If the contact continues,
slow down until it stops. Driving
too fast or spinning the wheels
with chains on will damage the
vehicle.
If a Tire Goes Flat
It is unusual for a tire to blow out
while driving, especially if the tires
are maintained properly. SeeTires
0 298. If air goes out of a tire, it is
much more likely to leak out slowly.
But if there ever is a blowout, 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 off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and
may require the same correction as
used in a skid. Stop pressing the
accelerator pedal and steer to
straighten the vehicle. It may be
very bumpy and noisy. Gently brake
to a stop, well off the road,
if possible.{Warning
Driving on a flat tire will cause
permanent damage to the tire.
Re-inflating a tire after it has been
driven on while severely
underinflated or flat may cause a
blowout and a serious crash.
Never attempt to re-inflate a tire
that has been driven on while
severely underinflated or flat.
Have your dealer or an authorized
tire service center repair or
replace the flat tire as soon as
possible.
{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could

336 Vehicle Care
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to
suspension components. Use the
proper straps around the tires to
secure the vehicle.
Use only a flatbed tow truck for
towing a disabled vehicle. Never
use a sling type lift or damage will
occur. Use ramps to help reduce
approach angles if necessary.
A towed vehicle should have its
drive wheels off the ground.
Consult a professional towing
service if the disabled vehicle must
be towed.
Caution
Improper use of the tow eye can
cause vehicle damage. Use
caution and low speeds to
prevent damage to the vehicle.
If the vehicle is equipped with tow
eye, only use the tow eye to pull the
vehicle onto a flatbed car carrier
from a flat road surface. Do not use
the tow eye to pull the vehicle from
snow, mud or sand.
The tow eye is located underneath
the load floor, near the spare tire or
the compressor kit, if equipped.
Carefully open the cover in the
fascia by using the small notch that
conceals the tow eye socket.
Install the tow eye into the socket
and turn it until it is fully tightened.
When the tow eye is removed,
reinstall the cover with the notch in
the original position.
Recreational Vehicle
Towing
Recreational vehicle towing refers to
towing the vehicle behind another
vehicle, such as behind a motor
home. The two most common types
of recreational vehicle towing are
known as dinghy towing and dolly

the instrument panel fuse
block. See
Instrument Panel
Fuse Block 0295.
Remember to reinstall the fuses
once the destination has been
reached.
Caution
If 105 km/h (65 mph) is exceeded
while towing the vehicle, it could
be damaged. Never exceed
105 km/h (65 mph) while towing
the vehicle.
Caution
Towing the vehicle from the rear
could damage it. Also, repairs
would not be covered by the
vehicle warranty. Never have the
vehicle towed from the rear.

wheels on the ground and the front
wheels on a dolly: 1. Put the front wheels on a dolly.
