NOTICE

■

When adding engine coolant

Wait until the engine has cooled down before adding engine coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot engine too
quickly can cause damage to the engine.

■

To prevent damage to the cooling system

Observe the following precautions:

●

Avoid contaminating the coolant with foreign matter (such as sand or dust
etc.).

●

Do not use any coolant additive.

5-2. Steps to take in an emergency

If the vehicle becomes stuck

■

Emergency hook

Carry out the following procedures if the tires spin or the vehicle

becomes stuck in mud, dirt, or snow.

Stop the engine. Set the parking brake and put the shift
lever in P.

Remove the mud, snow, or sand from around the stuck tire.

Place wood, stones or some other material to help provide
traction under the tires.

Restart the engine.

Shift the shift lever to D or R and carefully apply the accel-
erator to free the vehicle.

Turn off the TRAC and/or VSC systems if it is difficult to get out
because of TRAC and/or VSC operation. (

P. 142)

When your vehicle becomes stuck and
cannot move, the emergency hook is
used for another vehicle to pull your vehi-
cle out in an emergency. 
Your vehicle is not designed to tow
another vehicle.

5-2. Steps to take in an emergency

CAUTION

■

When attempting to free a stuck vehicle

If you choose to rock the vehicle back and forth to free it, make sure the sur-
rounding area is clear, to avoid striking other vehicles, objects or persons.
The vehicle may also lunge forward or lunge back suddenly as it becomes
free. Use extreme caution.

■

When shifting the shift lever

Be careful not to shift the shift lever with the accelerator pedal depressed. 
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.

NOTICE

■

To avoid damaging the transmission and other components

●

Avoid spinning the wheels and do not rev the engine.

●

If the vehicle remains stuck after trying these procedures, the vehicle may
require towing to be freed.

5-2. Steps to take in an emergency

If your vehicle has to be stopped in an emergency

Only in an emergency, such as if it becomes impossible to stop the

vehicle in the normal way, stop the vehicle using the following pro-

cedure:

Steadily step on the brake pedal with both feet and firmly
depress it.

Do not pump the brake pedal repeatedly as this will increase the
effort required to slow the vehicle.

Shift the shift lever to N.

If the shift lever is shifted to N

After slowing down, stop the vehicle in a safe place by the
road. 

Stop the engine.

If the shift lever cannot be shifted to N

Keep depressing the brake pedal with both feet to reduce
vehicle speed as much as possible.

Stop the engine by turning the
engine switch to the ACC
position.

Stop the vehicle in a safe place by the road.

318

5-2. Steps to take in an emergency

CAUTION

■

If the engine has to be turned off while driving

●

Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.

●

Never attempt to remove the key, as doing so will lock the steering wheel.

Engine oil selection

“Toyota Genuine Motor Oil” is used in your Scion vehicle. Use Scion
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the fol-
lowing grade and viscosity.

Oil grade: ILSAC GF-5 multigrade engine oil

Recommended viscosity: SAE 0W-20

SAE 0W-20 is the best choice for
good fuel economy and good
starting in cold weather.

If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which

allows cold startability. Oils with a lower value before the W allow
for easier starting of the engine in cold weather.

• The 20 in 0W-20 indicates the viscosity characteristic of the oil

when the oil is at high temperature. An oil with a higher viscosity
(one with a higher value) may be better suited if the vehicle is oper-
ated at high speeds, or under extreme load conditions.

How to read oil container label:
The International Lubricant Specification Advisory Committee
(ILSAC) Certification Mark is added to some oil containers to help
you select the oil you should use.

Fuel information

■

Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your Scion has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.

■

Gasoline quality

In very few cases, driveability problems may be caused by the brand of gas-
oline you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your Scion dealer.

■

Gasoline quality standards

●

Automotive manufacturers in the U.S.A., Europe and Japan have devel-
oped a specification for fuel quality called World-Wide Fuel Charter
(WWFC), which is expected to be applied worldwide.

●

The WWFC consists of four categories that are based on required emis-
sion levels. In the U.S., category 4 has been adopted.

●

The WWFC improves air quality by lowering emissions in vehicle fleets,
and improves customer satisfaction through better performance.

■

Recommendation of the use of gasoline containing detergent additives

●

Scion recommends the use of gasoline that contains detergent additives
to avoid build-up of engine deposits.

●

All gasoline sold in the U.S.A. contains minimum detergent additives to
clean and/or keep clean intake systems, per EPA’s lowest additives con-
centration program.

●

Scion strongly recommends the use of Top Tier Detergent Gasoline. For
more information on Top Tier Detergent Gasoline and a list of marketers,
please go to the official website www.toptiergas.com.

You must only use unleaded gasoline in your vehicle. 

Select octane rating 87 (Research Octane Number 91) or higher. Use

of unleaded gasoline with an octane rating lower than 87 may result

in engine knocking. Persistent knocking can lead to engine damage.

At minimum, the gasoline you use should meet the specifications
of ASTM D4814 in the U.S.A.

330

6-1. Specifications

■

Recommendation of the use of cleaner burning gasoline

Cleaner burning gasoline, including reformulated gasoline that contains oxy-
genates such as ethanol or MTBE (Methyl Tertiary Butyl Ether) is available in
many areas.

Scion recommends the use of cleaner burning gasoline and appropriately
blended reformulated gasoline. These types of gasoline provide excellent
vehicle performance, reduce vehicle emissions and improve air quality.

■

Non-recommendation of the use of blended gasoline

●

If you use gasohol in your vehicle, be sure that it has an octane rating no
lower than 87.

●

Scion does not recommend the use of gasoline containing methanol.

■

Non-recommendation of the use of gasoline containing MMT

Some gasoline contains an octane enhancing additive called MMT (Methyl-
cyclopentadienyl Manganese Tricarbonyl).

Scion does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.

The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your Scion dealer for service.

●

Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).

DO NOT use gasoline 
containing more than 
15% ethanol.

(30% ethanol)

(50% ethanol)

(85% ethanol)
